Dear readers,
Here we go again with a new issue
full of amazing contents. This month we
start with our contributor Alakananda
Mookerjee and a topic that is generating
huge discussion: should the Internet be
free? What would the pros and cons be?
A conversation is now starting to bubble
over novel modes of extending connec-
tivity to those parts of the world where
almost 4.5 million citizens remain uncon-
nected, by beaming it down from space.
Medicine is facing one of the most chal-
lenging problems of the century and the
message of the World Health Organization
could not be more clear: antibiotic resis-
tance will kill 300 million people by 2050
if we do not find and develop new anti-
biotics. Ellie Pownall has been taking the
pulse of the situation to bring some light;
what future is awaiting us?
Joe Baylis comes with a new energy
concept that has been gaining a great
deal of attention in the engineering com-
munity over the past year. Known as a
“solar road”, it would essentially turn our
transport infrastructure system into one
huge renewable power station. Find out
more in his article.
Anthroposophic Medicine is a holistic
therapy that treats the individual from an
integral approach. Anette Bopp, one of
the main experts in this field, has written
the article we bring you in this issue.
Finally, Olga Antczak, from the University
of Lodz, has kindly shared with our read-
ers her latest research about the extreme
habitats of dragonfly development, a
valuable scientific paper.
Thanks for reading. And remember: com-
ment, share and spread the word!

ust as it’s absurd for 21st cen-
tury citizens—at least in the
industrialized West—to read a
book in the flickering halo of
a gas lamp, it’s equally odd being
offline. The Internet, a seemingly
invisible tool, has become so intrinsic
to our lives that we’ve come to regard
it as vital as clean water and electric-
ity.

So, when in the middle of last
year, when the American Federal
Communications Commission,
under pressure from the internet
service provider lobby, proposed a
new set of rules wherein U.S. tele-
com giants like Verizon, Comcast,
AT&T, and Time Warner Cable would
be able to bifurcate the ‘information
highway’ into a so-called
‘fast lane’ and a
‘slow lane’, there
was an uproar.
P r o t e s t e r s
s h r i e k e d
that that’d
kill ‘network
n e u t ra l i t y ’,
the long-stand-
ing concept that
internet service
providers treat all data
equally and fairly, regardless of
whether it’s bits and bytes of The
New Yorker or a song on Spotify
or a banter on WhatsApp. They
shouldn’t play favorites with pack-
ets of data—they demanded. Under
the new arrangement, a company
like Netflix or Hulu would have to
pay a ‘toll’ to allow their content
to be streamed more speedily into
our tablets or televisions. And if
they paid more, they’d make us
pay more. Aside from fattening our
monthly bills, it’d also put a damp-
ener on innovations whose very
bedrock is the Internet.
Fortunately, the crisis
was averted. Nearly
4,000,000 letters
from consum-
ers and advo-
cacy groups
poured into
the federal
agency, cajol-
ing it to save
the Internet from
falling into the
hands of corporate profi-
teers. In response, in a statement
to WIRED, Mr. Tom Wheeler wrote,
“the Internet must be fast, fair, and
open”. And so it will remain—for
now and in the future. Yet, what we
perceive as an indispensable util-
ity, without which we find ourselves
isolated, lost, and bored, is a lux-
ury that 4,400,000,000 across the
“the Internet must be fast,
fair, and open”
world have no access
to. Not yet touched by
the hand of the internet
god, they don’t know
what is to be ‘connect-
ed’. But a conversation
is now starting to bub-
ble over novel modes of
extending connectivity
to them by beaming it
down from space—but
more on that later.
When you send an
e-mail, you casual-
ly tap on the ‘send’
button. Whoosh. And
like that, it’s gone. You
think nothing of it after
that, secure in the cer-
tainty that it’ll pop up
in another inbox, near,
far, or very, very far
away. You couldn’t be
sniggered at for think-
ing that it flew away on
the wingtips of a fire-
drake. After all, there’s
so little of this service
that we can see—noth-
ing beyond our laptop,
router, and modem.

In reality, the Internet
has a Cyclopean physi-
cal architecture, made
of a zoo of computers
and a dense mesh of
wires that girdle around
the globe. Once your
message leaves your
desk, say, in Chicago,
it’s broken down into
small pieces. And then
it hops from telephone
pole to telephone pole
until it reaches land’s
end.
Next, it journeys
through optical fibers—
each an incredibly thin
strand of glass or plastic
that serves as a path-
ways for information—
sealed in submarine
cables that run along
level stretches of the
seabed, carefully avoid-
ing coral reefs, sunken
ships, marine troughs
and ridges, and fish-
beds, before arriving
at its destination, say,
Beijing. The diameter
of a deep-water cable
is roughly that of a gar-
den hose (0.7 inches)
while those in shallow-
er waters are thicker,
about the cross-section
of a soda can (2.7 inch-
es). Similarly, when
someone in Los Angles
wants to read the life-
style section of the
leading English daily,
The Times, she keys
in its U.R.L. A request
to retrieve it goes out.
From wherever it is—
presumably, London—
it travels through the
7
cold, dark depths of the Atlantic to
her internet service provider’s ter-
minal. It’s a short hop from there
to her desktop. At this time, there
are 278 active cables. Together,
they loop around for some 555,000
miles under the sea, linking all the
continents, barring Antarctica and
a few island nations. (For perspec-
tive -- Mount Everest stands five
miles tall). And it is this aquatic
grid that powers the overwhelming
bulk of our internet.
While on the go, it can be reached
on a smartphone through a cell
phone tower. Reception is excel-
lent at a Starbucks, in New York’s
Time’s Square, but as you move
away from bustling urban pockets,
it tends to get sluggish and patchy,
until it dwindles to naught. Driving
along a rural section of Asia’s Grand
Trunk Road, your device will receive
hardly any signal at all. Worse still,
what if you’re in an area in the mid-
dle of nowhere, where there’s not
even a radio mast and an aerial in
the vicinity? Then, the only way to
log on is by means of telecom sat-
ellites. These are pieces of school
bus-size machinery that are placed
in what is known as a ‘geostation-
ary orbit’. As Earth spins, they spin
with it, in tandem, 22,236 miles
above the surface, in a circular
path, like a hoopla hoop, along the
plane of Earth’s midriff.
Cell Phone Tower
To an observer, looking out the
window, therefore, they’d appear to
be stationary, hovering at the same
position night after night. They’re
so placed such that ground-based
antennas, which ‘talk’ to them, don’t
have to keep rotating to keep track
of them. They serve as enormous
mirrors in space, capable of bounc-
ing off telephone calls, television
and radio broadcasts, and internet
content, from one sector of the
world to another. This is how they
work. You’re on a luxury liner, sail-
ing on the Aegean Sea, and you’d
like to call someone in Istanbul.
As you place your call, your phone
connects to the ship’s on-board,
‘transmitter’, which then beams it
up to a ‘receiver’ up on a satellite in
an ‘uplink’. The satellite’s transmit-
ter, in turn, sends it back down in
a ‘downlink’ to another receiver on
the Turkish coast, from where it’s
then routed to the recipient. The
entire process takes place within a
flash. But while it works wonderful-
ly for a standard, voice-only phone
call, it may not if you were trying
to tweet from the deck or download
‘War and Peace’ on your e-reader
from inside your cabin.
Presently, satellites are slowpokes
when it comes to providing entry to
the Internet. Signals from Earth—
in the form of radio waves, which
travel at the same speed as light—
take 0.25 seconds to make one
round-trip. While that may sound
like an infinitesimal time frame,
it’s not small enough to support a
real-time video call, made through
an application like Skype. As of
2006, satellites handled a surpris-
8
9
ing 1% of the volume
of all telecom traffic.
But that could change
if the vision of a couple
of Silicon Valley tech
tycoons materializes.
Elon Musk is the
founder of SpaceX, a
Hawthorne, California-
based private space
firm. Its spacecraft,
Dragon, made history
in May, 2012, when it
became the first com-
mercial vehicle to dock
with the International
Space Station. After
retiring the Space
Shuttle four years ago,
NASA handed it the
job of ferrying cargo to
the orbiting lab. (The
American crew, how-
ever, so far, still hitch
rides with the Russians,
aboard Soyuz). He
also has a finger in
other bleeding-edge
pies: Tesla (maker of
high-end electric cars);

solar power equip-
ment); Hyperloop (a
concept tube transport
that will hurtle passen-
gers from Los Angeles
to San Francisco in
roughly half an hour, at
a tearing 598 m.p.h.)
And now, he’s fallen
hard for the notion of
bringing high-speed
internet (repeat: high-
speed) to everyone,
everywhere, through a
swarm of 4,000 minia-
ture Sputniks, buzzing
around in low Earth
orbit—just 750 miles up
in the sky. Greg Wyler
of OneWeb has plans
to put up a smaller
fleet of 648. His proj-
ect is expected to be
up and running before
the end of the decade
and is expected to cost
$2 billion.
Keeping the satel-
lites wheeling closer to
home will reduce the
lag by a wide margin:
to a mere 0.006 sec-
onds. On the down-
side, the area covered
by each will be very
11
limited, about the size the New
Mexico. Their narrow reach, how-
ever, is compensated for by their
multitude. Sometimes, it’s hard to
put your imagination to work, if the
capital required to make it happen is
an astronomical sum (if you’ll par-
don the pun). But both these enter-
prises have attracted the pocket-
books of big-name players. Search-
engine titan Google and an inves-
tor, Fidelity, have plunked down $1
billion into Musk’s venture, which
carries a price tag of a staggering
$10 billion. Richard Branson’s Virgin
Galactic and Qualcomm, on the
other hand, are backing OneWeb.
The media splash made by these
recent announcements has eclipsed
the success of 03b, which has been
in the business since before all the
hoopla began.
The Channel Islands-based com-
pany (OneWeb) was the first to
offer broadband service to a size-
able geographic belt, running 45
degrees north and south of the
equator. By placing a constellation
of a dozen satellites at 5,000 miles,
it’s been able to cut the delay to
0.15 seconds, making connections
more energetic. The cost of put-
ting a satellite in orbit depends
on its size and how far away from
Earth it’ll be deployed. They can
weigh anywhere between one kilo-
gram (such as CubeSat) to over
1,000. O3b’s products are 700 kilo-
CubeSat satellites
12

(Google Loon launch event , June 2013)
grams when fully fueled. To make
the technology more feasible, it’s
imperative that satellites be built
more compactly and lighter so that
a single rocket launch can transport
a big batch. O3b has sent up four at
a time. While Google has invested
in Musk’s endeavor, it’s also fine-
tuning an experiment of its own to
haul service to the Internet boon-
docks in rural, far-flung regions.
‘Loon’, like the orbital propos-
als, is about delivering connectivity
from above but while also staying

Wi-Fi matrix that will offer 3G-like
speeds. In that serene ‘near-space’,
where the air is thin, dry, and nippy,
they’ll have no trucking with com-
mercial jets or weather-related tur-
bulence—but only different layers
of winds. These dirigibles will scud
away to wherever they’re needed
by hitchhiking on the back of a cold
stream, moving north, south, east,
or west. To test the program, 30
balloons were deployed above New
Zealand’s South Island, in June,
2013. Each unit can provide cover-
age to an area with a diameter of
25 miles. Below, in an apartment
complex, subscribers will be able
tap into it, using a bowl fixed on
their rooftop.
Not to be outshone,
Facebook, too, has
ambitions to develop
yet another kind of
network: a network of
massive drones that’ll
allow more people to
getonline.‘Connectivity
Lab’, unveiled in March
last year, envisions
hoisting sun-driven,
long-endurance fly-
ing machines that’ll
stay airborne uninter-
ruptedly for months.
At a recent Mashable-
hosted conference, Yael
Maguire, the project’s
director of engineer-
ing, said that they’d
be about the size of a
Boeing-747. Facebook
is yet to announce
when they’ll roll out.
Since the end of the
Cold War, we haven’t
seen fiercer competi-
tion in the aerospace
sphere. Only, this isn’t
a race between two
nations but among cor-
porations, all belonging
to one nation. Also, it’s
not a race to put up
weapons of destruc-
tion but instruments
of empowerment. Not
all of it is motivated
by altruism, of course.
Some of it is driven by
greed. There’s money
to be made and lots of
it. The more the eye-
balls, the more is the
advertising moolah.
But that’s not the end
of it. Mr. Musk intends
to channel that rev-

Antibiotic
Apocalypse
ince the likes of Sir Alexander
Fleming, the single greatest
contribution to medicine has
been necessary for all aspects
of health care; antibiotic’s. The reduc-
tion of risk in open wound surgery,
infections and cancer treatments has
been massive, not only prolonging the
lives of millions of people but also cre-
ating a spring board for new technol-
ogy and future discoveries. However,
we can ask ourselves how much pro-
gression have we made since the orig-
inal brilliance of Sir Fleming in 1928.

The most recent discovery of a new
class of antibiotics was in the 1980’s1,
and there are only two companies left
(GlaxoSmithKline and AstraZeneca) in
a shrinking field of research into new
antibiotics which are slow and expen-
sive to develop2
.
Some journalistic publications such
as Nature Magazine, were able to shed
some light on the diminishing horizons
for the future of antibiotic’s, suggest-
ing that the key to the success of new
antibiotics is screening uncultured
bacteria - through which a new anti-
biotic, ‘Teixobactin’ has been found.
Teixobactin inhibits cell wall synthe-
sis by binding to a highly conserved
motif of lipid II (precursor of peptido-
glycan) and lipid III (precursor of cell
wall teichoic acid3). This development
arguably suggests a new path for the
discovery of antibiotic’s and only time
will tell how far this new method will
reproduce the diminishing support
behind new antibiotic progression.
16
17
A recent arti-
cle by the BBC
outlined that a
“terrible future
could be on the
horizon4
” and
this along with
warnings from
theWorldHealth
Organization
and The US cen-
tres of disease
control, states
there will be an
emergence of
“nightmare bacteria”
and an “apocalypse”
of disease. The anti-
biotics we use every
day are so valuable to
life, scientists question
what we will do with-
out them.
From the tinniest
scratch, to open sur-
gery, these operations
will be increasingly
risky. It seems a grave
future for the develop-
ment of antibiotic pro-
gression lies ahead;
the brilliance that was
nineteenth century sci-
entific bacterial discov-
eries has simmered to
an end and, whether
the technology needed
to discover new anti-
biotics is simply too
advanced or there is
no existing new strains
of antibiotic to discover
is debatable.
Developing antibiot-
ics poses problems -
both commercially and
economically: Dr Brad
Spellberg, one of the
authors of the 2004
IDSA report Bad Bugs,
No Drugs expresses:
“Antibiotics, in particu-
lar, have a poor return
on investment because
they are taken for a
short period of time
and cure their tar-
get disease. In con-
trast, drugs that treat
chronic illness, such as
high blood pressure,
are taken daily for
the rest of a patient’s
life. “Companies have
In 1928 Alexander Fleming (1881–1955) discovered
penicillin, made from the Penicillium notatum mold.
figured out that they
make a lot more money
selling the latter drugs
than they do selling
antibiotics,” Spellberg
says, “highlighting the
lack of incentive for
companies to develop
antibiotic”5
. The lack
of initiative to produce
new antibiotics is a
clear flaw in the plan
to revolutionise
a n t i b i o t i c
medicine.
While the
lack of
i n t e r e s t
in creat-
ing these
n e w
treatments is
clearly due to expense,
some companies how-
ever are still working
hard to improve this
technology.
Dr John H Rex, Head
of Infection and Global
MedicinesDevelopment
at AstraZeneca recent-
ly spoke about the dan-
gers of antimicrobial
resistance on National
Public Radio’s “To the
Point” show6
, during
which he noted that he
is terrified at the pros-
pect of returning to a
pre-antibiotic era. This
display of the true con-
cerns for the develop-
ment of antibiotics as
they are; hard to dis-
cover, hard to devel-
op, and the econom-
ics difficult to manage;
suggests scientists are
still working increas-
ingly hard to assist in
developing new strains
of antibiotic, even if
some corporations have
deemed it too expen-
sive.
The resistance against
antibiotics is commonly
described as the situ-
ation when the con-
centration of antibiotic
needed to kill the bacte-
ria cannot be achieved
at the site of infection.
However, if a bacteria is
resistant to one strain
of antibiotic this does
not mean it will be to
a new or differ-
ent type. This
highlights
the need
for new
a n t i b i o t-
ics to pre-
vent bacteria that is
resistant to multiple
types of treatment,
named ‘multi-resis-
tant’. There are many
works being done to
prevent the spread of
multi-resistant bac-
teria for example, “A
group of International
experts came togeth-
er through a joint ini-
18
19
tiative by the European Centre
for Disease Prevention and Control
(ECDC) and the centres for disease
Control and Prevention (CDC), to
create a standardized international
terminology with which to describe
acquired resistance profiles in
Staphylococcusaureus,Enterococus
spp, Enterobacteria (other than
salmonella and shigella), pseudo-
monas aeruginosa and
Acinetobacter spp.,
all bacteria often
responsible for
h e a l t h c a r e -
a s s o c i a t e d
i n f e c t i o n s
and prone
to multi-
drug resis-
tance7
”. The
result of
this was cre-
ating three
different sub-
categories for
Antibiotics to be
placed: MDR, XDR,
and PDR. These help to categorize
different antibiotics’ and determine
how they would be tested for each
relevant bacterium, how to define
resistance within an antimicrobial
category and be epidemiologically
meaningful. For example penicillin
using the antimicrobial agent ampi-
cillin, the bacterium Citrobacter
koseri (C. koseri) which contributes
to initiate brain abscess’s
during meningitis,
was found to be
resistant. It is
important to
subcategorise
and organise
the findings
of these
results to
e n s u r e
whichstrains
of resistance
are increasing
and eventual-
ly, how we will
prevent them. This
new way of categoriz-

ing antibi-
otic’s will
hopefully
decrease
the chanc-
es of an
antibiot-
ic apoca-
lypse by
enabling
scientists
to find
new tech-
niques to
d e v e l o p
the antibi-
otic’s that
h e a l t h
care sys-
tems and
s u r g e r y
practices can use to prevent the
spread of disease and risk of oper-
ations.
An article named “A new antibi-
otic kills pathogens without detect-
able resistance8
” by Dr. Lewis, out-
lines the development of sever-
al methods to grow uncultured
organisms by cultivation in-situ or
by using specific growth factors.
Texiocbactin, as previously stated,
was discovered in a screen of uncul-
tured bacteria. It states “This mol-
ecule, which we named teixobactin,
is an unusual depsipeptide which
contains enduracididine, methyl-
phenylalanine, and four D-amino
acids. The biosynthetic gene clus-
ter (GenBank accession number
KP006601) was identified using a
homology search (Supplementary
21
Discussion).” This shows the devel-
opment of homology searches and
the hope that future gene clusters
will contain new antibiotic informa-
tion that we can use and re-develop.
The article is optimistic, stating that
“Teixobactin has excellent activity
against Gram-Positive Pathogens,
including drug-resistant strains”.
This is vital for companies such as
GlaxoSmithKline and AstraZeneca
researching a new antibiotic to
replace resistant strains. The new
antibiotic is arguably a break in the
seemingly bleak period of scientific
discovery in this field. Scientists
suggest that “Inhibition of teichoic
acid synthesis by teixobactin would
help liberate autolysins, contribut-
ing to the excellent lytic and kill-
ing activity of this antibiotic”, sug-
gesting a stronger, more powerful
antibiotic will be developed and
available in the future. The devel-
opment of “teichoic acid synthesis”
is arguably a procedure which can
be used on future new develop-
ments of bacteria and therefore
improve the strength and stability
of this medicine in killing bacteria
in patients. Of course, one antibi-
otic will not change the course of
a scientific apocalypse in prevent-
ing patients from infections, and a
future of discovery will be needed
to prevent this outbreak of newly
resistant biotic strains.
The new field of resistance from the
body is an ideology which scientists
hope to erase, the CDC (Centres
for Disease Control and Prevention)
are fighting to produce clearer
patient instruction to reduce the
risk of antibiotic resistance. Many
aspects of antibiotic resistance rely
on the understanding of patients,
for example, if a patient were to
not finish the prescribed amount of
antibiotic. The NHS explains that
“Strains of bacteria can mutate,
over time, become resistant to a
specific antibiotic. The chance of
this increases if a person does not
finish the course of antibiotics as
some bacteria may be left to devel-
op resistance.”9
This highlights the
importance of the patient being
fully aware of the need to finish a
course of antibiotics and therefore
can prevent the urgency of the
need for new strains of antibiotics,
in some cases.
22
The Department of Microbiology,
Hospital Ramón y Cajal, Madrid,
Spain, suggest a theory of how
to minimize the development of
antibiotic resistance. Stating that
“Bacterial populations harbouring
determinants of antibiotic resis-
tance will be selected for by a
range of antibiotic concentrations
which are able to suppress or slow
the growth of susceptible popula-
tions.” Suggesting the new strain
of anti-biotic which will be produced
in the future, is a positive change
from previous antibiotic develop-
ments. This article describes how
the new development of antibi-
otic will regard both the interests
of the individual patient but also
the ecological impact of different
drugs and their delivery schedules.
This will be done by controlling the
concentrations within the human
body in a series of compartments,
This poster, for example, describes the correct measures to prevent a completely
resistant future for antibiotics. The development of patient information and guidance
is deemed just as important as the development of new antibiotics and anti-resistant
science.
23
where the potential selective power
will be roughly proportional to the
time of exposure of bacteria to the
drug (selective period). This will
make the antibiotic more powerful
and less likely to be resistant as
it won’t be in full contact with the
bacteria for a long period of time.

suggests these new antibiotic will
be able to fight against resistance
and therefore create a more eco-
nomic and effect pool of medicine.
However, there is still the case of
finding these new strains of antibi-
otic resistance in order to prevent
the growth of resistant bacterial
populations.
Overall, the existence of usable
antibiotics is slowly coming to an
end and it is up to scientists such
as Dr. Lewis and the department of
microbiology, to discover new ways

to find strains of antibiotic which
have not yet been discovered, in
order to restart the cycle of dis-
ease cured by antibiotic’s leading
to good health. The importance of
antibiotic development is seem-
ingly overlooked by funding pro-
grammes, however scientists con-
tinue to work excessively to develop
a way for antibiotic’s to function at
the same level of effectiveness as
previous discoveries. The rising of
‘Teixobactin’ holds a good lead for
future development. Although the
rate of development and discovery
of antibiotics is exceedingly slow,
the outcome will prevent bacterial
resistance and eventually, continue
the effectiveness of treatments in
diseases and infections.

You’d be forgiven for treating this
proposal with cynicism. It does
sounds like it’s too good to be
true. Indeed, several well-qualified
people have protested passionately
and pessimistically, ‘proving’ that
this idea will never work.
Worry not however! The pioneers
continue to push on, and more
recent developments late in 2014
have put things back on track.
But how bright is the future of
solar roads really? Will we ever
get the chance to literally walk on
sunshine? Let’s take a look at the
complicated journey the solar road
concept has taken so far, and the
pros and cons of the technology.
Back in 2006, Mr and Mrs Brusaw,
an engineering couple in Idaho,
USA, started work on the idea of
replacing roadways with hexagonal
smart solar panels strong enough
on which to drive the heaviest of
vehicles.
They developed their idea fur-
ther before, in 2014, announcing
to the world that it was time to
enter it into reality, in the form
of a boorishly attention-grabbing
YouTube video called Solar Freakin’
And they’re off!

funding campaign that
went on for two months
and managed to raise
2.2 million American
dollars - that’s twice
what they were aim-
ing for. To add to this,
the American Federal
Highway Administration
had previously invested
$750,000. This big idea
was obviously capturing
the public’s and state’s
attention.
And frankly, why
wouldn’t it? If you don’t
have the time or the
disposition to watch the
above video in full, then
here’s a brief list of the
proposed benefits:
•	 Production of
enough clean renewable
energy to supply the
USA with three times
its needs (assuming
the whole road network
was transformed). The
worries of global warm-
ing and our dependence

on dwindling fossil fuels
would be allayed.
•	 The surplus ener-
gy could then be sold
so that the solar pan-
els effectively pay for
themselves.
•	 Buildings would
plug directly into the
road, and electric cars
could be charged as
they drive.
•	 The panels are more
durable then tarmac
and so reduce mainte-
nance costs, especially
as repairs would simply
involve directly replac-
ing each damaged tile.
•	 The panels have
LEDs installed, meaning
that the road can light
up ahead of cars, flash
warning signals and
reconfigure at a touch
of a button (great for
car parks, playgrounds
and managing traffic
flow).
•	 The panels have
pressure sensors so
can warn drivers of
any obstructions in the
road ahead (especially
attractive for unlit roads
in regions where large
wildlife roam danger-
ously in the darkness).
•	 The panels contain
heating elements so can
clear the road of ice and
snow constantly, pre-
venting untold numbers
of accidents.
Of course, the pro-
cess of transforming
the whole US road net-

work would be a slow and gradual
one with large initial expenditures.
Nonetheless, most would agree
that the ideas presented are cer-
tainly very exciting.
As with any new and exciting
development, there are plenty of
people out there looking to debunk
this concept; armed with realism
(some may read pessimism), they
argue that the project is just far
too ambitious. Unfortunately for
the yea-sayers, these critics have
some valid points. The below is a
useful video:
h t t p s : / / w w w . y o u t u b e . c o m /
watch?v=H901KdXgHs4
The main argument is that, in the
absence of real data, the maths
simply does not add up, even with
some very generous assumptions
made. The solar panels alleged-
ly will never be able to produce
enough energy to power even their
own LEDs, let alone provide energy
to the grid, pay for themselves,
heat up and filter water. It is argued
that they will end up losing money.
This primary concern is made up of
the following problems:
•	 Thickness of glass. The pro-
posed glass has to be thick enough
to withstand huge pressure and
rough enough for added traction.
This means less light can reach the

solar panels underneath, reducing
their efficiency.
•	 The LEDs are unlikely to be vis-
ible during the day. What ramifica-
tions does this have for warning
systems and lane configurations?
•	 There is no information avail-
able regarding stopping distances
on this new glass surface. Of par-
ticular concern is stopping in wet
conditions.
•	 Dust, dirt and organic matter
mean the roads will need regular
cleaning for the solar cells to remain
efficient. Wear, tear and scratches
will also reduce the amount of light
reaching the cells. And most roads
are lined by large objects like trees,
preventing light from reaching the
surface.
•	 It is impossible to angle the
solar panels towards the sun as it
moves across the sky, as with other
solar panels, further reducing effi-
ciency.
The most efficient solar panels track the movement of the sun and have very thin, clear glass. Even these
take approximately a decade to ‘pay for themselves’
30
•	 The interlocking
nature of the tiles means
that varying loads will
displace each tile in dif-
ferent ways, creating
an uneven and danger-
ous road surface more
susceptible to weather-
ing.
•	 How will roads get
the energy in the win-
ter to melt ice when the
angle of the sun is low,
cloud cover is high and
snow is covering the
solar panels?
•	 The project
will be incredibly
expensive to get
off the ground.
C u t t i n g - e d g e
technology, com-
plex wiring and
solar panels do
not come cheap.
•	 How will such
high-tech com-
ponents fare

environments

of frost and
heat.
•	 What  about
the problem of
theft? Valuable
pieces of
equipment will
be placed in
remote areas – moni-
toring is nigh on impos-
sible.
•	 Car parks will be
useless given that they
are commonly covered
in cars during the day,
when all the sunlight is
around for business.

attacks be addressed?
This has the potential of
causing absolute havoc.
•	 What about light
pollution? This is already
proving to be an annoy-
ance around the world.
Laying down roads that
light up won’t exactly
help the situation.
Admittedly, it does
look like a worrying col-
lection of set-backs and
opponents simply say,
why not just cover the
millions of empty roofs
around the world with
proven, high efficiency
solar panels?
So, does this spell the
end of solar roadways?
I wouldn’t be so sure…
The Brusaws refuse
to take these criticisms
lying down and have
issued answers to many
FAQs. For example, their
embossed glass design
will not only create trac-
tion but also refract light
onto the sensors below,
apparently reducing the
problem of the changing
angle of the sun. Some
of these replies are a
little generic and wool-
ly though, so a direct
rebuttal to the critics,
with hard facts and fig-
ures, would be useful.
The FAQ section of their
website can be found in
the link below.
http://www.solarroad-
ways.com/faq.shtml
But it’s not all about
the Brusaws. This idea
is also being developed
in the Netherlands, with
the building of a solar
cycle path in the north-
ern town of Krommenie.
A 70 metre stretch of
road is actually current-
ly in use (something
that has been missing
from the Idaho cam-
paign) and supports
around 2000 cyclists a
day, cost 3million Euros
to build (half covered
by the government)
and, an extension of
100 metres, will power
three houses.
Initially developed by
TNO (a Dutch scien-
tific research compa-
ny), the design is called
SolaRoad, and is slight-
ly different to Solar
Freakin’ Roadways. One
variation for example,
is that the solar cells
are embedded in rect-
angular concrete slabs
rather than in a tessel-
lating pattern.
A step forward
33
The main difference though, is
that they have put more emphasis
on green energy rather than ‘extra
benefits’. The engineers behind this
project are hopeful it could be
expanded more to the main roads
to help power traffic lights and
cars in the future, but not to the
same outrageous extent as their
American cousins. This shift in
focus renders a lot of the criticisms
more irrelevant, which opponents
have acknowledged.
So, maybe this is 2-1 to the pio-
neers…
It is clear that we are still in
a period of trials and testing
for these solar roads, and the
Dutch example demonstrated
this in December 2014 (a month
after opening). Cold weather
caused the top layer to become
detached from its anchor and
so a metre section was deacti-
vated.
But, before the cynics pounce,
this is just par for the course for
any ground breaking project. It
wouldn’t be a trial without a few
tribulations.
The emergence of SolaRoad has
stifled protestations somewhat,
because it seems to be more of a
well thought out, sensible and real-
istic project. However, many are
indeed still focussing on the sheer
expense of such a project, which is
a fair point to some extent, espe-

cially if you live
in the dream-
land that is
Solar Freakin’
Roadways.
The Brusaws
and others say
that starting small will
generate capital to build
more, but even that doesn’t look
likely, considering how far off we
are from actually making a profit
on these things. As much as we’d
all love to believe that there will
still be energy left over to sell, the
compelling maths shown by crit-
ics shows that this is very far from
reality.
To give some kind of perspective,
one such astronomical estimate
of the total cost of Solar Freakin’
Roadways is 56 trillion dollars (or
around $20 million per mile), which
is just under four times the national
debt of the USA. This is admittedly
only an estimate, and is one of the
only ones available. The Brusaws
are yet to have offered an official
detailed quote, which is actually
quite worrying in itself.
the total cost of Solar Freakin’
Roadways is 56 trillion dollars (or
around $20 million per mile), which
is just under four times the national
debt of the USA.
On the other side of the Atlantic,
the Dutch SolaRoad, assuming it
will lengthen to 100m, will cost
around 3 million Euros (3.5 million
dollars), which seems expensive
considering that it will only pro-
duce enough energy to power three
houses. But that’s neither here nor
there. It is what this 3 million rep-
resents that is important – a step
towards a renewable and sustain-
able future.
Excitingly, many institutions and
organisations are commercial-
ly interested in this concept. For
example the Mayor of London, Boris
Johnson, has been mulling over the
possibility of installing these road-

ways in the UK’s capital. There is
one caveat here though - his focus
is currently on the Brusaws’ cam-
paign. I would urge him to remain
a little closer to home and look into
the Dutch offering first (especially
considering Boris’ obsession with
cycling).
Several critics of the solar road
concept do actually agree that it is
an attractive project and shouldn’t
necessarily be cast asunder. In
this world though, profitability is
a barrier to all things; if some-
thing doesn’t make money it won’t
become mainstream. This rules out
the all singing all dancing Solar
Freakin’ Roadways at least for now,
as we simply do not have the capi-
tal. However, it is important not to
squash the idea into the ground. To
shoot down pioneering work is to
halt the progression of the human
race. Let’s start at a grassroots
level and build from there.
Projects like the Dutch SolaRoad
are useful for smaller, more niche
applications like high-tech parks,
playgrounds, pavements and cycle
paths. And who knows, we may
see some serious developments in
the future. First, traffic lights may
be powered using this technology,
then streetlights, then cars, then
whole streets. Sooner or later who’s
to say we can’t end up with cities?
Research into renewable alterna-
tives to fossil fuels is essential. With
time, breakthrough will build upon
breakthrough and we will emerge
with a sustainable energy source
that will benefit the whole planet. It
is this goal that we must focus on.

Anthroposophic
Medicine
ore and more patients want to be
treated not only by conventional
therapies but also in a holistic
way with complementary meth-
ods and therapies. This is for good rea-
son: an individual is not simply a body;
there is also psyche and personality to be
taken into account as well. Furthermore,
every human being lives in a certain pro-
fessional, personal, and social context.
Anthroposophic medicine has occupied
this subject in a holistic-integrative man-
ner for more than 90 years.
37
Anthroposophic medi-
cine is not an ‘alter-
native medicine’. It
doesn’t seek to replace
conventional medicine.
On the contrary – it is an
extension of it, dealing
not only with the phys-
ical but also with the
soul and spirit. Based
on accepted medi-
cal science, it draws
on everything useful
that modern medicine
has to offer: medical
technology, laborato-
ry tests, medication,
operations, and inten-
sive care. But that’s
not the only benefit. In
addition, it assesses the
individual as a whole
entity, examining the
aspects that determine
a person’s uniqueness
according to anthro-
posophical norms. For
instance, this may
include physique and
body language, physi-
cal flow, handshake,
sleeping habits, sen-
sitivity to changes in
temperature, breath-
ing, and biorhythms.
Anthroposophic medi-
cine therefore attempts
to include the individu-
ality of the patient, as
well as the accepted
features of an illness,
in the treatment pro-
cess. For just as each
person is unique, so is
each treatment.
Anthroposophic medi-
cine is not pre-deter-
mined. It avoids pure
routine. Even if the
same disease pic-
tures constantly recur,
each illness mani-
fests itself differently
in each patient – a
manifestation insepa-
rable from the unique-
ness of the individual.
Anthroposophic medi-
cine therefore aims to
form a picture of the
physical, psychologi-
cal, and personal cir-
cumstances that have
paved the way for an
illness to take hold.
Taking such factors into
consideration during
diagnosis and therapy
and re-applying the
process to every new
patient, guided by sci-
entific findings, medi-
cal experience, per-
38
sonal discernment, and
intuition, is fundamen-
tal to anthroposophic
medicine. Any medi-
cine that ignores the
person as an individual
cannot claim to be true
human medicine.
Moreover, anthropo-
sophic medicine sup-
plements conventional
medicine with various
special forms of treat-
ment. These include
naturopathic medi-
cines, modified physi-
cal and palliative treat-
ments (involving baths,
compresses, bandages
and special [rhythmic]
massages) as well as
artistic forms of treat-
ment, such as sculp-
ture, painting, music
therapy, elocu-
tion, and euryth-
my therapy. The
aim of all artistic
forms of treat-
ment is that the
patient stimu-
lates the internal
healing process
of body and soul
under guidance
from their thera-
pist.

39
only as long as necessary. In cases
of acutely severe and life-threat-
ening illness, the use of allopathic
or conventional drugs (like antibi-
otics or cortisone, etc.) is usually
unavoidable. However, whenever
possible, symptoms are not sup-
pressed; instead the intention is to
activate powers of self-healing with
the aid of homeopathic and other
produced anthroposophic drugs and
to stimulate the body into finding
its own natural rhythm once more.
In this field, anthroposophic medi-
cine follows a holistic and pluralistic
approach.
A well-known example of a typi-
cal anthroposophic drug therapy is
mistletoe, which is used as medici-
nal plant in oncology. In Europe
it’s the most common and most
investigated drugs in integrative
oncology. More than one hundred
clinical studies have proved the
advantages in quality of life when
patients used mistletoe in addition
to, e.g., chemotherapy, radiation,
or other conventional cancer treat-
ments. Some studies even indicate
that there is also the possibility of
life extension.
With its synthesis of natural and
spiritual science anthroposoph-
ic medicine links the conventional
pathogenic approach (focusing on
the illness) to a salutogenic medical
perspective (focusing on health).
This produces a holistic apprecia-
tion of health, illness, and treat-
ment – and that’s exactly what
modern humanity needs. In this
day and age, patients don’t want to
be seen merely as an illness, but as
a person with an illness.
Anthroposophic medicine is
practised in more than 80 coun-
tries around the world: in Cape
Town and Helsinki, Moscow and
Los Angeles, Hamburg and Manila,
and Sao Paulo and Santiago de
Chile. The first anthroposoph-
ic hospital for acute care was
G e m e i n s c h a f t s k r a n k e n h a u s
Herdecke (www.gemeinschaftsk-
rankenhaus.de), founded in 1969.
It has a capacity of 471 beds for
all important medical departments
with 1250 employees and more than
50,000 patients a year (inpatients
40
and outpatients). Moreover, there
are another two big hospitals for
acute care in Berlin and Stuttgart
and eleven specialized hospitals,
rehabilitation clinics, or medical
departments. In addition, there are
professional associations for thera-
pists and nurses and a civil organ-
isations like GESUNDHEIT AKTIV
– Anthroposophic Medicine
(www.gesundheit-aktiv.de), which
stands for a holistic health system.

Abstract:
ypical biotopes inhabited
by the dragonflies’ larvae
are rivers, creeks, streams,
lakes, ponds, bogs, as well
as tanks in excavation pits. It turns
out, however, that there are species
of dragonflies resistant to severe
environmental conditions, capable
of living in very unusual habitats.
There are species inhabiting water-
falls, saline water or even tempo-
rary desert pools. Several tropical
species inhabit “plant-held waters”
- phytotelmata – water bodies in
leaves, roots, tree hollows. There
are also terrestrial or semi-terrestrial
dragonflies, which are adapted to
live in moss, on wet rocks or ground
litter. The diversity of habitats and
adaptations of dragonflies related to
these harsh conditions is enormous.
These dragonflies enrich the ecosys-
tems, as an important component of
food webs, and their presence cer-
tainly increases the aesthetic value
of the landscape. The importance
of protecting these extraordinary
developmental habitats is crucial in
context of the conservation of the
odonata fauna.

1.	
Introduction
Dragonflies (Odonata)
are widespread hemi-
metabolous insects.
They are amphibiotic -
their larvae are strong-
ly associated with the
aquatic environment,
while adults are flying
insects connected with
water throughout their
lives, especially during
oviposition.
According to the type
of inhabited micro-
habitat, there are two
groups of dragonflies’
larvae - one living on
sand or gravel as well
as decomposed organic
matter, and the second
one being phytophiles
living mainly among
macrophytes.
Those microhabitats
are mainly found in run-
ningwaters,bothnatural
and anthropogenic, like
rivers, streams, drain-
age ditches or channels.
Equally preferable are
different kinds of stand-
ing waters like lakes,
ponds, bogs, swamps,
as well as tanks in gravel
pits, quarries, clay and
peat excavations. But
in some cases, tiny and
temporary water reser-
voirs, like phytotelmata
seem to be enough.
2.	Discussion
What we call an
extreme place to live
is relative, but for this
review the extremely
challenging habitats,
which require special
adaptations from drag-
onflies living there,
were selected.
Thefirstspeciesissemi-
terrestrial Uropetala
carovei, which inhab-
its highland spring-fed
bogs in New Zealand
(Wolfe 1953, Corbet
1962, Silsby 2001). It
drills little burrows in the
seepage area, often with
two openings or sev-
eral ‘chambers’ on the
basis (Fig.1). However,
there was no case of
finding more than one
larva in single burrow
(Wolfe 1953). Larvae
live in the chambers
embedded in a fine silt
with their caudal plates
above. The burrows are
constructed in such a
way as to allow water
infiltration to the inside,
so that they are provid-
ed with the necessary
moisture to breathe
through their rectal gill.
Therefore, Uropetala
larvae can spend even
several months out of
the water (Wolfe 1953,
Corbet 1999). That
construction can take
various forms, depen-
dent on several factors.
Firstly the larva lives
just below the water
level, but older instars
are found at the great-
er depth (Wolfe 1953).
Uropetala dragonflies
also use their burrows
for hunting. They show
nocturnal activity, when
the entrances of their
burrows are even less
visible. The darkness is
used to hunt for small
arthropods by taking
them by surprise (Wolfe
1953, Winstanley &
Rowe 1980).
44
Fig. 1. The burrow of Uropetala
carovei – type with several
chambers (Wolfe 1953, modi-
fied)
Similar burrows are
drilled by the other
Petaluridae larvae,
for example Petalura
gigantea, which was
described by Tillyard
(1911).
In addition, a few fully
terrestrial species, like
Hawaiian Megalagrion
oahuense, are known.
Its habitat is a rhi-
zome mat of ferns like
Dicranopteris linearis or
Gleichenia sp. growing
on the steep hillsides
(Corbet 1962, Silsby
2001). The larvae
breathe using atmo-
spheric oxygen thanks
to the high humidity of
the air. Moreover, they
have a few morpho-
logical adaptations to
prevent excessive loss
of moisture - they are
stocky and hairy, their
body is strongly short-
ened and their caudal
lamellae are squat and
thickly covered with
setae (Corbet 1962).
	Larvae, which
inhabit reservoirs peri-
odically drying out,
have to deal with simi-
lar problems. Australian
Synthemis eustalacta
occupies summer-dry
pools and is able to
survive in shallow, dry
sand up to 10 weeks
without being moist-
ened. After this period
of time the larva is so
dry that in its first con-
tact with water it floats
on the surface (Tillyard
1910, Corbet 1999). It
is probably also caused
by the structure of the
hydrophobic wax cov-
ering the body sur-
face (Corbet 1999).
However, there are not
many drought-resis-
tant larvae. Common
adaptation for droughts
is a modification of
voltinism (Suhling et
al. 2004, Corbet et al.
2006). Odonata often
use the strategy of
accelerating the devel-
opment cycle in order
45
to emerge from the pool
before drying out. It is
an especially common
mechanism for the sea-
sonal-rainfall pools in
deserts (Corbet 1999,
Suhling et al. 2004). In
contrast, some dragon-
flies can withhold their
development by the
egg diapause. Indian
Potamarcha congener
can have the eggs in
that state up to 80
days (Corbet 1999).
During the temporary
zone larvae often get
buried in the wet sand
and when the pond gets
refilled by water, they
continue their devel-
opment (Corbet 1999,
Suhling et al. 2004).
Another species of
this genus, Megalagrion
amaurodytum (= M.
koelense) breeds in
the leaf axils of Astelia
and Freycinetia in the
wet upland forests of
Hawaii, although it is
able to survive with-
out the water (Corbet
1962). Studies of
Howarth and Watson
show that M. amau-
rodytum, as well as
Pseudocordulia spe-
cies, can even climb out
if placed in free water
(Corbet 1999). Williams
(1936) described also
other Megalagrion
larvae crawling in a
water-film on rocks. In
many species of this
genus the reduction of
gills and tracheae is
observed (Richards &
Davies 1977).
Worldwide 47 drag-
onfly species are known
to use phytotelmata as
a larval habitat (Corbet
1999). Lyriothemis tri-
color is an example of
development in tree
holes in India (Das et
al. 2013), whereas in
Borneo this is prob-
ably the most impor-
tant habitat in the for-
est ecosystem (Corbet
1999). Water in these
tanks is characterized
by specific physical and
chemical conditions,
such as low pH, high
content of dissolved
solids and nutrients,
and oxygen deficien-
cies. Therefore, the
larvae have to have
high tolerance to such
conditions. In addition,
there are even such
adaptations as canni-
balism. Megaloprepus
caerulatus appears to
be the best example
of this mechanism.
Only one larva can sur-
vive for 1-2 liters of
water in a tree hollow
(Fincke 1994, 2011).
In smaller habitats the
larva, which hatched
first, can patrol the
space, eating all newly
hatched larvae (Fincke
1996, 1999, 2011). In
the biggest hollows as
many as 30 larvae are
able to develop (Fincke
2011). This behavior
provides them sooner
emergence at a larger
size (Fincke 2011).
46
Mecistogaster orna-
ta larvae use a differ-
ent strategy to gain
the necessary quanti-
ty of dissolved oxygen
in tree hollow tanks –
some of them live in
symbiosis with algae
growing on the dorsal
surface of their body,
including caudal lamel-
lae. They face towards
the sunlight, enabling
the photosynthesis of
the algae (de la Rosa
& Ramirez-Ulate 1995,
Corbet 1999).
Despite the most often
occupied phytotelma-
ta by Odonata being
Bromeliaceae tanks as
well as leaf axils of
other plants and tree
cavities, there are also
species found in even
smaller water bodies,
like Hadrothemis cama-
rensis, which is able
to develop in bamboo
stamps (Corbet 1962).
Obviously, many of
these untypical micro-
h a b i t a t s
are fac-
u l t a t i ve ,
occupied
in case of
lack of the
more suit-
able sites
( C o r b e t
1 9 6 2 ,
S i l s b y
2001).
There
are also
s e v e r a l
d r a g o n -
flies, which ovipos-
it and develop solely
in ‘extreme’ habitats.
The larvae of the only
true marine species,
Erythrodiplax berenice,
is unable to develop
in freshwater (Wright
1943, Smith & Smith
1996), however in lab-
oratory studies they
have managed to live
in the tap water for one
month (Smith & Smith
1996). The natural
habitats of this dragon-
fly are rocky mangrove

flats and tidal marshes (Dunson
1980, Smith & Smith 1996, Corbet
1999). Optimal salinity for them is
around 36-38 ppt, although they
are able to live in sea water up to
260% thanks to osmoregulatory
abilities (Dunson 1980). Several
Odonata occupy brackish water of
varying salinity – on San Salvador
(the Bahamas) these ecosystems
are inhabited by Erythemis sim-
plicicollis, Orthemis ferruginea and
Pantala flavescens (Smith & Smith
1996).
	 Another interesting larval habi-
tat is waterfalls. The best known
example is the African dragonfly
Zygonyx natalensis. After copula-
tion, they fly in tandem through
the water spray and then a female
oviposits in the mats of roots, bryo-
zoans or moss in the spray zone
along a waterfall (Corbet 1962,
Martens 1991). In Panama and
Costa Rica Thaumatoneura inopina-
ta shows similar behavior (Calvert
1914, Silsby 1991). These larvae
are able to live on the wet vertical
rocks behind rapidly falling water
thanks to the dorsoventrally flat-
tened body and long powerful legs
with strong claws (Silsby 1991).

develop in such
harsh habitats?
very unusual and extraordinary lar-
val development habitats has been
described with probably plenty more
to be yet discovered.
3.	conclusion
	 Why do Odonata develop in such
harsh habitats? One of the answers
is definitely lack of other convenient
breeding sites. What is more impor-
tant, in most of such places there
are not many predators. Therefore,
the adaptations to the living in
extreme habitats, like high saline
waters and waterfalls, are
often the survival strat-
egy (Calvert 1914, Corbet
1999). In p hy t o -
telmata, for example, dragonfly
and damselfly larvae are known to
be the top predators (Fincke 1994).
	 Furthermore, relatively large
amounts of terrestrial and semi-
terrestrial Megalagrion damselflies
on Hawaii are most likely the result
of adaptive radiation. Jordan et al.
(2003) pointed out that high lev-
els of endemism and species rich-
ness can be correlated with islands’
ages. The emergence of the new
island allowed the larvae to colo-
nize the available ecological niche
by developing new adaptations
49
and thus, many different ecological
guilds were established (Jordan et
al. 2003). Consequently, species of
this genus inhabit equal amount of
habitats as all other damselflies in
the world combined (Simon 1987).
Moreover, the larvae had the pos-
sibility to colonize phytotelmata
and terrestrial habitats due to the
historical absence of mammals and
ants in Hawaii (Jordan et al. 2003).
	 Zimmerman (2001) presumes
that the terrestrial Megalagrion
oahuense larvae could, in the future,
be an ancestor for the new order
of insects, which would evolve in
Hawaii.
	 One thing is certain - the
survival of these extraordinary
Odonata depends in greater scale
on human activity. The ecosystems
inhabited by dragonflies are under
strong human pressure. It affects
mainly tropical habitats, which are
a hotspot of dragonfly biodiver-
sity. In addition, these dragonflies
are an essential component of the
food web in many ecosystems.
Therefore, there is an urgent need
for their protection.

This month we start with our contributor Alakananda Mookerjee and a topic that is generating huge discussion: should the Internet be free? What would the pros and cons be? A conversation is now starting to bubble over novel modes of extending connec- tivity to those parts of the world where almost 4.5 million citizens remain uncon- nected, by beaming it down from space. Medicine is facing one of the most chal- lenging problems of the century and the message of the World Health Organization could not be more clear: antibiotic resis- tance will kill 300 million people by 2050 if we do not find and develop new anti- biotics. Ellie Pownall has been taking the pulse of the situation to bring some light; what future is awaiting us? Joe Baylis comes with a new energy concept that has been gaining a great deal of attention in the engineering com- munity over the past year. Known as a “solar road”, it would essentially turn our transport infrastructure system into one huge renewable power station. Find out more in his article. Anthroposophic Medicine is a holistic therapy that treats the individual from an integral approach. Anette Bopp, one of the main experts in this field, has written the article we bring you in this issue. Finally, Olga Antczak, from the University of Lodz, has kindly shared with our read- ers her latest research about the extreme habitats of dragonfly development, a valuable scientific paper.

The Internet, a seemingly invisible tool, has become so intrinsic to our lives that we’ve come to regard it as vital as clean water and electric- ity.

  • 5. 4 So, when in the middle of last year, when the American Federal Communications Commission, under pressure from the internet service provider lobby, proposed a new set of rules wherein U.S. tele- com giants like Verizon, Comcast, AT&T, and Time Warner Cable would be able to bifurcate the ‘information highway’ into a so-called ‘fast lane’ and a ‘slow lane’, there was an uproar. P r o t e s t e r s s h r i e k e d that that’d kill ‘network n e u t ra l i t y ’, the long-stand- ing concept that internet service providers treat all data equally and fairly, regardless of whether it’s bits and bytes of The New Yorker or a song on Spotify or a banter on WhatsApp. They shouldn’t play favorites with pack- ets of data—they demanded. Under the new arrangement, a company like Netflix or Hulu would have to pay a ‘toll’ to allow their content to be streamed more speedily into our tablets or televisions. And if they paid more, they’d make us pay more. Aside from fattening our monthly bills, it’d also put a damp- ener on innovations whose very bedrock is the Internet. Fortunately, the crisis was averted. Nearly 4,000,000 letters from consum- ers and advo- cacy groups poured into the federal agency, cajol- ing it to save the Internet from falling into the hands of corporate profi- teers. In response, in a statement to WIRED, Mr. Tom Wheeler wrote, “the Internet must be fast, fair, and open”. And so it will remain—for now and in the future. Yet, what we perceive as an indispensable util- ity, without which we find ourselves isolated, lost, and bored, is a lux- ury that 4,400,000,000 across the “the Internet must be fast, fair, and open”

But a conversation is now starting to bub- ble over novel modes of extending connectivity to them by beaming it down from space—but more on that later. When you send an e-mail, you casual- ly tap on the ‘send’ button. Whoosh. And like that, it’s gone. You think nothing of it after that, secure in the cer- tainty that it’ll pop up in another inbox, near, far, or very, very far away. You couldn’t be sniggered at for think- ing that it flew away on the wingtips of a fire- drake. After all, there’s so little of this service that we can see—noth- ing beyond our laptop, router, and modem. 5
  • 7. 6 In reality, the Internet has a Cyclopean physi- cal architecture, made of a zoo of computers and a dense mesh of wires that girdle around the globe. Once your message leaves your desk, say, in Chicago, it’s broken down into small pieces. And then it hops from telephone pole to telephone pole until it reaches land’s end. Next, it journeys through optical fibers— each an incredibly thin strand of glass or plastic that serves as a path- ways for information— sealed in submarine cables that run along level stretches of the seabed, carefully avoid- ing coral reefs, sunken ships, marine troughs and ridges, and fish- beds, before arriving at its destination, say, Beijing. The diameter of a deep-water cable is roughly that of a gar- den hose (0.7 inches) while those in shallow- er waters are thicker, about the cross-section of a soda can (2.7 inch- es). Similarly, when someone in Los Angles wants to read the life- style section of the leading English daily, The Times, she keys in its U.R.L. A request to retrieve it goes out. From wherever it is— presumably, London— it travels through the
  • 8. 7 cold, dark depths of the Atlantic to her internet service provider’s ter- minal. It’s a short hop from there to her desktop. At this time, there are 278 active cables. Together, they loop around for some 555,000 miles under the sea, linking all the continents, barring Antarctica and a few island nations. (For perspec- tive -- Mount Everest stands five miles tall). And it is this aquatic grid that powers the overwhelming bulk of our internet. While on the go, it can be reached on a smartphone through a cell phone tower. Reception is excel- lent at a Starbucks, in New York’s Time’s Square, but as you move away from bustling urban pockets, it tends to get sluggish and patchy, until it dwindles to naught. Driving along a rural section of Asia’s Grand Trunk Road, your device will receive hardly any signal at all. Worse still, what if you’re in an area in the mid- dle of nowhere, where there’s not even a radio mast and an aerial in the vicinity? Then, the only way to log on is by means of telecom sat- ellites. These are pieces of school bus-size machinery that are placed in what is known as a ‘geostation- ary orbit’. As Earth spins, they spin with it, in tandem, 22,236 miles above the surface, in a circular path, like a hoopla hoop, along the plane of Earth’s midriff. Cell Phone Tower
  • 9. To an observer, looking out the window, therefore, they’d appear to be stationary, hovering at the same position night after night. They’re so placed such that ground-based antennas, which ‘talk’ to them, don’t have to keep rotating to keep track of them. They serve as enormous mirrors in space, capable of bounc- ing off telephone calls, television and radio broadcasts, and internet content, from one sector of the world to another. This is how they work. You’re on a luxury liner, sail- ing on the Aegean Sea, and you’d like to call someone in Istanbul. As you place your call, your phone connects to the ship’s on-board, ‘transmitter’, which then beams it up to a ‘receiver’ up on a satellite in an ‘uplink’. The satellite’s transmit- ter, in turn, sends it back down in a ‘downlink’ to another receiver on the Turkish coast, from where it’s then routed to the recipient. The entire process takes place within a flash. But while it works wonderful- ly for a standard, voice-only phone call, it may not if you were trying to tweet from the deck or download ‘War and Peace’ on your e-reader from inside your cabin. Presently, satellites are slowpokes when it comes to providing entry to the Internet. Signals from Earth— in the form of radio waves, which travel at the same speed as light— take 0.25 seconds to make one round-trip. While that may sound like an infinitesimal time frame, it’s not small enough to support a real-time video call, made through an application like Skype. As of 2006, satellites handled a surpris- 8

Elon Musk is the founder of SpaceX, a Hawthorne, California- based private space firm. Its spacecraft, Dragon, made history in May, 2012, when it became the first com- mercial vehicle to dock with the International Space Station. After retiring the Space Shuttle four years ago, NASA handed it the job of ferrying cargo to the orbiting lab.

And now, he’s fallen hard for the notion of bringing high-speed internet (repeat: high- speed) to everyone, everywhere, through a swarm of 4,000 minia- ture Sputniks, buzzing around in low Earth orbit—just 750 miles up in the sky. Greg Wyler of OneWeb has plans to put up a smaller fleet of 648. His proj- ect is expected to be up and running before the end of the decade and is expected to cost $2 billion. Keeping the satel- lites wheeling closer to home will reduce the lag by a wide margin: to a mere 0.006 sec- onds. On the down- side, the area covered by each will be very

Sometimes, it’s hard to put your imagination to work, if the capital required to make it happen is an astronomical sum (if you’ll par- don the pun). But both these enter- prises have attracted the pocket- books of big-name players. Search- engine titan Google and an inves- tor, Fidelity, have plunked down $1 billion into Musk’s venture, which carries a price tag of a staggering $10 billion. Richard Branson’s Virgin Galactic and Qualcomm, on the other hand, are backing OneWeb. The media splash made by these recent announcements has eclipsed the success of 03b, which has been in the business since before all the hoopla began. The Channel Islands-based com- pany (OneWeb) was the first to offer broadband service to a size- able geographic belt, running 45 degrees north and south of the equator. By placing a constellation of a dozen satellites at 5,000 miles, it’s been able to cut the delay to 0.15 seconds, making connections more energetic. The cost of put- ting a satellite in orbit depends on its size and how far away from Earth it’ll be deployed. They can weigh anywhere between one kilo- gram (such as CubeSat) to over 1,000.

To make the technology more feasible, it’s imperative that satellites be built more compactly and lighter so that a single rocket launch can transport a big batch. O3b has sent up four at a time. While Google has invested in Musk’s endeavor, it’s also fine- tuning an experiment of its own to haul service to the Internet boon- docks in rural, far-flung regions. ‘Loon’, like the orbital propos- als, is about delivering connectivity from above but while also staying put with- in Earth’s a t m o - s p h e r e .

In that serene ‘near-space’, where the air is thin, dry, and nippy, they’ll have no trucking with com- mercial jets or weather-related tur- bulence—but only different layers of winds. These dirigibles will scud away to wherever they’re needed by hitchhiking on the back of a cold stream, moving north, south, east, or west. To test the program, 30 balloons were deployed above New Zealand’s South Island, in June, 2013. Each unit can provide cover- age to an area with a diameter of 25 miles.

Not to be outshone, Facebook, too, has ambitions to develop yet another kind of network: a network of massive drones that’ll allow more people to getonline.‘Connectivity Lab’, unveiled in March last year, envisions hoisting sun-driven, long-endurance fly- ing machines that’ll stay airborne uninter- ruptedly for months. At a recent Mashable- hosted conference, Yael Maguire, the project’s director of engineer- ing, said that they’d be about the size of a Boeing-747. Facebook is yet to announce when they’ll roll out. Since the end of the Cold War, we haven’t seen fiercer competi- tion in the aerospace sphere. Only, this isn’t a race between two nations but among cor- porations, all belonging to one nation. Also, it’s not a race to put up weapons of destruc- tion but instruments of empowerment. Not all of it is motivated by altruism, of course. Some of it is driven by greed. There’s money to be made and lots of it. The more the eye- balls, the more is the advertising moolah. But that’s not the end of it. Mr. Musk intends to channel that rev- enue into funding a similar infrastructure 13

  • 16. 15 Antibiotic Apocalypse ince the likes of Sir Alexander Fleming, the single greatest contribution to medicine has been necessary for all aspects of health care; antibiotic’s. The reduc- tion of risk in open wound surgery, infections and cancer treatments has been massive, not only prolonging the lives of millions of people but also cre- ating a spring board for new technol- ogy and future discoveries. However, we can ask ourselves how much pro- gression have we made since the orig- inal brilliance of Sir Fleming in 1928. S by ellie pownall website www.ispectrummagazine.com
  • 17. The most recent discovery of a new class of antibiotics was in the 1980’s1, and there are only two companies left (GlaxoSmithKline and AstraZeneca) in a shrinking field of research into new antibiotics which are slow and expen- sive to develop2 . Some journalistic publications such as Nature Magazine, were able to shed some light on the diminishing horizons for the future of antibiotic’s, suggest- ing that the key to the success of new antibiotics is screening uncultured bacteria - through which a new anti- biotic, ‘Teixobactin’ has been found. Teixobactin inhibits cell wall synthe- sis by binding to a highly conserved motif of lipid II (precursor of peptido- glycan) and lipid III (precursor of cell wall teichoic acid3). This development arguably suggests a new path for the discovery of antibiotic’s and only time will tell how far this new method will reproduce the diminishing support behind new antibiotic progression. 16
  • 18. 17 A recent arti- cle by the BBC outlined that a “terrible future could be on the horizon4 ” and this along with warnings from theWorldHealth Organization and The US cen- tres of disease control, states there will be an emergence of “nightmare bacteria” and an “apocalypse” of disease. The anti- biotics we use every day are so valuable to life, scientists question what we will do with- out them. From the tinniest scratch, to open sur- gery, these operations will be increasingly risky. It seems a grave future for the develop- ment of antibiotic pro- gression lies ahead; the brilliance that was nineteenth century sci- entific bacterial discov- eries has simmered to an end and, whether the technology needed to discover new anti- biotics is simply too advanced or there is no existing new strains of antibiotic to discover is debatable. Developing antibiot- ics poses problems - both commercially and economically: Dr Brad Spellberg, one of the authors of the 2004 IDSA report Bad Bugs, No Drugs expresses: “Antibiotics, in particu- lar, have a poor return on investment because they are taken for a short period of time and cure their tar- get disease. In con- trast, drugs that treat chronic illness, such as high blood pressure, are taken daily for the rest of a patient’s life. “Companies have In 1928 Alexander Fleming (1881–1955) discovered penicillin, made from the Penicillium notatum mold.
  • 19. figured out that they make a lot more money selling the latter drugs than they do selling antibiotics,” Spellberg says, “highlighting the lack of incentive for companies to develop antibiotic”5 . The lack of initiative to produce new antibiotics is a clear flaw in the plan to revolutionise a n t i b i o t i c medicine. While the lack of i n t e r e s t in creat- ing these n e w treatments is clearly due to expense, some companies how- ever are still working hard to improve this technology. Dr John H Rex, Head of Infection and Global MedicinesDevelopment at AstraZeneca recent- ly spoke about the dan- gers of antimicrobial resistance on National Public Radio’s “To the Point” show6 , during which he noted that he is terrified at the pros- pect of returning to a pre-antibiotic era. This display of the true con- cerns for the develop- ment of antibiotics as they are; hard to dis- cover, hard to devel- op, and the econom- ics difficult to manage; suggests scientists are still working increas- ingly hard to assist in developing new strains of antibiotic, even if some corporations have deemed it too expen- sive. The resistance against antibiotics is commonly described as the situ- ation when the con- centration of antibiotic needed to kill the bacte- ria cannot be achieved at the site of infection. However, if a bacteria is resistant to one strain of antibiotic this does not mean it will be to a new or differ- ent type. This highlights the need for new a n t i b i o t- ics to pre- vent bacteria that is resistant to multiple types of treatment, named ‘multi-resis- tant’. There are many works being done to prevent the spread of multi-resistant bac- teria for example, “A group of International experts came togeth- er through a joint ini- 18
  • 20. 19 tiative by the European Centre for Disease Prevention and Control (ECDC) and the centres for disease Control and Prevention (CDC), to create a standardized international terminology with which to describe acquired resistance profiles in Staphylococcusaureus,Enterococus spp, Enterobacteria (other than salmonella and shigella), pseudo- monas aeruginosa and Acinetobacter spp., all bacteria often responsible for h e a l t h c a r e - a s s o c i a t e d i n f e c t i o n s and prone to multi- drug resis- tance7 ”. The result of this was cre- ating three different sub- categories for Antibiotics to be placed: MDR, XDR, and PDR. These help to categorize different antibiotics’ and determine how they would be tested for each relevant bacterium, how to define resistance within an antimicrobial category and be epidemiologically meaningful. For example penicillin using the antimicrobial agent ampi- cillin, the bacterium Citrobacter koseri (C. koseri) which contributes to initiate brain abscess’s during meningitis, was found to be resistant. It is important to subcategorise and organise the findings of these results to e n s u r e whichstrains of resistance are increasing and eventual- ly, how we will prevent them. This new way of categoriz- Photocredit:NationalInstituteofAllergyandInfectiousDiseases(NIAID) One form of Staphylococcus aureus bacteria known as methicillin-resistant Staphylococcus aureus, or MRSA, causes a range of illnesses, from skin and wound infections to pneumonia and bloodstream infections that can cause sepsis and death.

An article named “A new antibi- otic kills pathogens without detect- able resistance8 ” by Dr. Lewis, out- lines the development of sever- al methods to grow uncultured organisms by cultivation in-situ or by using specific growth factors. Texiocbactin, as previously stated, was discovered in a screen of uncul- tured bacteria. It states “This mol- ecule, which we named teixobactin, is an unusual depsipeptide which contains enduracididine, methyl- phenylalanine, and four D-amino acids. The biosynthetic gene clus- ter (GenBank accession number KP006601) was identified using a homology search (Supplementary
  • 22. 21 Discussion).” This shows the devel- opment of homology searches and the hope that future gene clusters will contain new antibiotic informa- tion that we can use and re-develop. The article is optimistic, stating that “Teixobactin has excellent activity against Gram-Positive Pathogens, including drug-resistant strains”. This is vital for companies such as GlaxoSmithKline and AstraZeneca researching a new antibiotic to replace resistant strains. The new antibiotic is arguably a break in the seemingly bleak period of scientific discovery in this field. Scientists suggest that “Inhibition of teichoic acid synthesis by teixobactin would help liberate autolysins, contribut- ing to the excellent lytic and kill- ing activity of this antibiotic”, sug- gesting a stronger, more powerful antibiotic will be developed and available in the future. The devel- opment of “teichoic acid synthesis” is arguably a procedure which can be used on future new develop- ments of bacteria and therefore improve the strength and stability of this medicine in killing bacteria in patients. Of course, one antibi- otic will not change the course of a scientific apocalypse in prevent- ing patients from infections, and a future of discovery will be needed to prevent this outbreak of newly resistant biotic strains. The new field of resistance from the body is an ideology which scientists hope to erase, the CDC (Centres for Disease Control and Prevention) are fighting to produce clearer patient instruction to reduce the risk of antibiotic resistance. Many aspects of antibiotic resistance rely on the understanding of patients, for example, if a patient were to not finish the prescribed amount of antibiotic. The NHS explains that “Strains of bacteria can mutate, over time, become resistant to a specific antibiotic. The chance of this increases if a person does not finish the course of antibiotics as some bacteria may be left to devel- op resistance.”9 This highlights the importance of the patient being fully aware of the need to finish a course of antibiotics and therefore can prevent the urgency of the need for new strains of antibiotics, in some cases.
  • 23. 22 The Department of Microbiology, Hospital Ramón y Cajal, Madrid, Spain, suggest a theory of how to minimize the development of antibiotic resistance. Stating that “Bacterial populations harbouring determinants of antibiotic resis- tance will be selected for by a range of antibiotic concentrations which are able to suppress or slow the growth of susceptible popula- tions.” Suggesting the new strain of anti-biotic which will be produced in the future, is a positive change from previous antibiotic develop- ments. This article describes how the new development of antibi- otic will regard both the interests of the individual patient but also the ecological impact of different drugs and their delivery schedules. This will be done by controlling the concentrations within the human body in a series of compartments, This poster, for example, describes the correct measures to prevent a completely resistant future for antibiotics. The development of patient information and guidance is deemed just as important as the development of new antibiotics and anti-resistant science.
  • 24. 23 where the potential selective power will be roughly proportional to the time of exposure of bacteria to the drug (selective period). This will make the antibiotic more powerful and less likely to be resistant as it won’t be in full contact with the bacteria for a long period of time. The department of Microbiology suggests these new antibiotic will be able to fight against resistance and therefore create a more eco- nomic and effect pool of medicine. However, there is still the case of finding these new strains of antibi- otic resistance in order to prevent the growth of resistant bacterial populations. Overall, the existence of usable antibiotics is slowly coming to an end and it is up to scientists such as Dr. Lewis and the department of microbiology, to discover new ways Dr. Kim Lewis (Northeastern University) Phototcredit:NortheasternUniversityBoston,Massachusetts
  • 25. 24 to find strains of antibiotic which have not yet been discovered, in order to restart the cycle of dis- ease cured by antibiotic’s leading to good health. The importance of antibiotic development is seem- ingly overlooked by funding pro- grammes, however scientists con- tinue to work excessively to develop a way for antibiotic’s to function at the same level of effectiveness as previous discoveries. The rising of ‘Teixobactin’ holds a good lead for future development. Although the rate of development and discovery of antibiotics is exceedingly slow, the outcome will prevent bacterial resistance and eventually, continue the effectiveness of treatments in diseases and infections. 1.Novel classes of antibiotics or more of the same? http://www.ncbi.nlm.nih.gov/pmc/articles/ PMC3085877/ 2.The Battle to Discover new Antibiotics http://www.telegraph.co.uk/finance/ newsbysector/pharmaceuticalsandchemi- cals/9010738/The-battle-to-discover-new- antibiotics.html 3.Uncultured Bacteria-The way forward http://www.nature.com/nature/journal/ v517/n7535/full/nature14098.html 4.BBC Article http://www.bbc.com/news/health-21702647 5.Bulletin of the World Health Organization- Race against time to develop new antibiotics 6.Bad News Bugs and The Need for New Antibiotics- Stephanie Fischer 7.Research into Multi-Resistant bacteria http://onlinelibrary.wiley.com/doi/10.1111/ j.1469-0691.2011.03570.x/full 8.A new antibiotic kills pathogens without detectable resistance- Losee L.

  • 27. 26 You’d be forgiven for treating this proposal with cynicism. It does sounds like it’s too good to be true. Indeed, several well-qualified people have protested passionately and pessimistically, ‘proving’ that this idea will never work. Worry not however! The pioneers continue to push on, and more recent developments late in 2014 have put things back on track. But how bright is the future of solar roads really? Will we ever get the chance to literally walk on sunshine? Let’s take a look at the complicated journey the solar road concept has taken so far, and the pros and cons of the technology. Back in 2006, Mr and Mrs Brusaw, an engineering couple in Idaho, USA, started work on the idea of replacing roadways with hexagonal smart solar panels strong enough on which to drive the heaviest of vehicles. They developed their idea fur- ther before, in 2014, announcing to the world that it was time to enter it into reality, in the form of a boorishly attention-grabbing YouTube video called Solar Freakin’ And they’re off!

To add to this, the American Federal Highway Administration had previously invested $750,000. This big idea was obviously capturing the public’s and state’s attention. And frankly, why wouldn’t it? If you don’t have the time or the disposition to watch the above video in full, then here’s a brief list of the proposed benefits: • Production of enough clean renewable energy to supply the USA with three times its needs (assuming the whole road network was transformed).

  • 30. 29 work would be a slow and gradual one with large initial expenditures. Nonetheless, most would agree that the ideas presented are cer- tainly very exciting. As with any new and exciting development, there are plenty of people out there looking to debunk this concept; armed with realism (some may read pessimism), they argue that the project is just far too ambitious. Unfortunately for the yea-sayers, these critics have some valid points. The below is a useful video: h t t p s : / / w w w . y o u t u b e . c o m / watch?v=H901KdXgHs4 The main argument is that, in the absence of real data, the maths simply does not add up, even with some very generous assumptions made. The solar panels alleged- ly will never be able to produce enough energy to power even their own LEDs, let alone provide energy to the grid, pay for themselves, heat up and filter water. It is argued that they will end up losing money. This primary concern is made up of the following problems: • Thickness of glass. The pro- posed glass has to be thick enough to withstand huge pressure and rough enough for added traction. This means less light can reach the Too good to be true How will LEDs be seen under conditions like this? Photo credit:homewaters-jim.blogspot.co.uk

What ramifica- tions does this have for warning systems and lane configurations? • There is no information avail- able regarding stopping distances on this new glass surface. Of par- ticular concern is stopping in wet conditions. • Dust, dirt and organic matter mean the roads will need regular cleaning for the solar cells to remain efficient. Wear, tear and scratches will also reduce the amount of light reaching the cells. And most roads are lined by large objects like trees, preventing light from reaching the surface. • It is impossible to angle the solar panels towards the sun as it moves across the sky, as with other solar panels, further reducing effi- ciency. The most efficient solar panels track the movement of the sun and have very thin, clear glass. Even these take approximately a decade to ‘pay for themselves’ 30
  • 32. • The interlocking nature of the tiles means that varying loads will displace each tile in dif- ferent ways, creating an uneven and danger- ous road surface more susceptible to weather- ing. • How will roads get the energy in the win- ter to melt ice when the angle of the sun is low, cloud cover is high and snow is covering the solar panels? • The project will be incredibly expensive to get off the ground. C u t t i n g - e d g e technology, com- plex wiring and solar panels do not come cheap. • How will such high-tech com- ponents fare in inhospitable environments e.g. the impact of frost and heat. • What about the problem of theft?

Laying down roads that light up won’t exactly help the situation. Admittedly, it does look like a worrying col- lection of set-backs and opponents simply say, why not just cover the millions of empty roofs around the world with proven, high efficiency solar panels? So, does this spell the end of solar roadways? I wouldn’t be so sure… The Brusaws refuse to take these criticisms lying down and have issued answers to many FAQs. For example, their embossed glass design will not only create trac- tion but also refract light onto the sensors below, apparently reducing the problem of the changing angle of the sun. Some of these replies are a little generic and wool- ly though, so a direct rebuttal to the critics, with hard facts and fig- ures, would be useful. The FAQ section of their website can be found in the link below. http://www.solarroad- ways.com/faq.shtml But it’s not all about the Brusaws. This idea is also being developed in the Netherlands, with the building of a solar cycle path in the north- ern town of Krommenie. A 70 metre stretch of road is actually current- ly in use (something that has been missing from the Idaho cam- paign) and supports around 2000 cyclists a day, cost 3million Euros to build (half covered by the government) and, an extension of 100 metres, will power three houses. Initially developed by TNO (a Dutch scien- tific research compa- ny), the design is called SolaRoad, and is slight- ly different to Solar Freakin’ Roadways. One variation for example, is that the solar cells are embedded in rect- angular concrete slabs rather than in a tessel- lating pattern. A step forward
  • 34. 33 The main difference though, is that they have put more emphasis on green energy rather than ‘extra benefits’. The engineers behind this project are hopeful it could be expanded more to the main roads to help power traffic lights and cars in the future, but not to the same outrageous extent as their American cousins. This shift in focus renders a lot of the criticisms more irrelevant, which opponents have acknowledged. So, maybe this is 2-1 to the pio- neers… It is clear that we are still in a period of trials and testing for these solar roads, and the Dutch example demonstrated this in December 2014 (a month after opening). Cold weather caused the top layer to become detached from its anchor and so a metre section was deacti- vated. But, before the cynics pounce, this is just par for the course for any ground breaking project. It wouldn’t be a trial without a few tribulations. The emergence of SolaRoad has stifled protestations somewhat, because it seems to be more of a well thought out, sensible and real- istic project. However, many are indeed still focussing on the sheer expense of such a project, which is a fair point to some extent, espe- Any word from the naysayers? ‘SolaRoad’ cells are embedded in concrete slabs, rather than tessellating panels Photocredit:Solaroad

The Brusaws and others say that starting small will generate capital to build more, but even that doesn’t look likely, considering how far off we are from actually making a profit on these things. As much as we’d all love to believe that there will still be energy left over to sell, the compelling maths shown by crit- ics shows that this is very far from reality. To give some kind of perspective, one such astronomical estimate of the total cost of Solar Freakin’ Roadways is 56 trillion dollars (or around $20 million per mile), which is just under four times the national debt of the USA. This is admittedly only an estimate, and is one of the only ones available. The Brusaws are yet to have offered an official detailed quote, which is actually quite worrying in itself. the total cost of Solar Freakin’ Roadways is 56 trillion dollars (or around $20 million per mile), which is just under four times the national debt of the USA. On the other side of the Atlantic, the Dutch SolaRoad, assuming it will lengthen to 100m, will cost around 3 million Euros (3.5 million dollars), which seems expensive considering that it will only pro- duce enough energy to power three houses. But that’s neither here nor there. It is what this 3 million rep- resents that is important – a step towards a renewable and sustain- able future. Excitingly, many institutions and organisations are commercial- ly interested in this concept. For example the Mayor of London, Boris Johnson, has been mulling over the possibility of installing these road- So… What’s next?

I would urge him to remain a little closer to home and look into the Dutch offering first (especially considering Boris’ obsession with cycling). Several critics of the solar road concept do actually agree that it is an attractive project and shouldn’t necessarily be cast asunder. In this world though, profitability is a barrier to all things; if some- thing doesn’t make money it won’t become mainstream. This rules out the all singing all dancing Solar Freakin’ Roadways at least for now, as we simply do not have the capi- tal. However, it is important not to squash the idea into the ground. To shoot down pioneering work is to halt the progression of the human race. Let’s start at a grassroots level and build from there. Projects like the Dutch SolaRoad are useful for smaller, more niche applications like high-tech parks, playgrounds, pavements and cycle paths. And who knows, we may see some serious developments in the future. First, traffic lights may be powered using this technology, then streetlights, then cars, then whole streets. Sooner or later who’s to say we can’t end up with cities? Research into renewable alterna- tives to fossil fuels is essential. With time, breakthrough will build upon breakthrough and we will emerge with a sustainable energy source that will benefit the whole planet. It is this goal that we must focus on.

  • 37. Literally integrative: by Anette Bopp M 36 Anthroposophic Medicine ore and more patients want to be treated not only by conventional therapies but also in a holistic way with complementary meth- ods and therapies. This is for good rea- son: an individual is not simply a body; there is also psyche and personality to be taken into account as well. Furthermore, every human being lives in a certain pro- fessional, personal, and social context. Anthroposophic medicine has occupied this subject in a holistic-integrative man- ner for more than 90 years.
  • 38. 37 Anthroposophic medi- cine is not an ‘alter- native medicine’. It doesn’t seek to replace conventional medicine. On the contrary – it is an extension of it, dealing not only with the phys- ical but also with the soul and spirit. Based on accepted medi- cal science, it draws on everything useful that modern medicine has to offer: medical technology, laborato- ry tests, medication, operations, and inten- sive care. But that’s not the only benefit. In addition, it assesses the individual as a whole entity, examining the aspects that determine a person’s uniqueness according to anthro- posophical norms. For instance, this may include physique and body language, physi- cal flow, handshake, sleeping habits, sen- sitivity to changes in temperature, breath- ing, and biorhythms. Anthroposophic medi- cine therefore attempts to include the individu- ality of the patient, as well as the accepted features of an illness, in the treatment pro- cess. For just as each person is unique, so is each treatment. Anthroposophic medi- cine is not pre-deter- mined. It avoids pure routine. Even if the same disease pic- tures constantly recur, each illness mani- fests itself differently in each patient – a manifestation insepa- rable from the unique- ness of the individual. Anthroposophic medi- cine therefore aims to form a picture of the physical, psychologi- cal, and personal cir- cumstances that have paved the way for an illness to take hold. Taking such factors into consideration during diagnosis and therapy and re-applying the process to every new patient, guided by sci- entific findings, medi- cal experience, per-

Moreover, anthropo- sophic medicine sup- plements conventional medicine with various special forms of treat- ment. These include naturopathic medi- cines, modified physi- cal and palliative treat- ments (involving baths, compresses, bandages and special [rhythmic] massages) as well as artistic forms of treat- ment, such as sculp- ture, painting, music therapy, elocu- tion, and euryth- my therapy. The aim of all artistic forms of treat- ment is that the patient stimu- lates the internal healing process of body and soul under guidance from their thera- pist.

  • 40. 39 only as long as necessary. In cases of acutely severe and life-threat- ening illness, the use of allopathic or conventional drugs (like antibi- otics or cortisone, etc.) is usually unavoidable. However, whenever possible, symptoms are not sup- pressed; instead the intention is to activate powers of self-healing with the aid of homeopathic and other produced anthroposophic drugs and to stimulate the body into finding its own natural rhythm once more. In this field, anthroposophic medi- cine follows a holistic and pluralistic approach. A well-known example of a typi- cal anthroposophic drug therapy is mistletoe, which is used as medici- nal plant in oncology. In Europe it’s the most common and most investigated drugs in integrative oncology. More than one hundred clinical studies have proved the advantages in quality of life when patients used mistletoe in addition to, e.g., chemotherapy, radiation, or other conventional cancer treat- ments. Some studies even indicate that there is also the possibility of life extension. With its synthesis of natural and spiritual science anthroposoph- ic medicine links the conventional pathogenic approach (focusing on the illness) to a salutogenic medical perspective (focusing on health). This produces a holistic apprecia- tion of health, illness, and treat- ment – and that’s exactly what modern humanity needs. In this day and age, patients don’t want to be seen merely as an illness, but as a person with an illness. Anthroposophic medicine is practised in more than 80 coun- tries around the world: in Cape Town and Helsinki, Moscow and Los Angeles, Hamburg and Manila, and Sao Paulo and Santiago de Chile. The first anthroposoph- ic hospital for acute care was G e m e i n s c h a f t s k r a n k e n h a u s Herdecke (www.gemeinschaftsk- rankenhaus.de), founded in 1969.

  • 43. T 42 Abstract: ypical biotopes inhabited by the dragonflies’ larvae are rivers, creeks, streams, lakes, ponds, bogs, as well as tanks in excavation pits. It turns out, however, that there are species of dragonflies resistant to severe environmental conditions, capable of living in very unusual habitats. There are species inhabiting water- falls, saline water or even tempo- rary desert pools. Several tropical species inhabit “plant-held waters” - phytotelmata – water bodies in leaves, roots, tree hollows. There are also terrestrial or semi-terrestrial dragonflies, which are adapted to live in moss, on wet rocks or ground litter. The diversity of habitats and adaptations of dragonflies related to these harsh conditions is enormous. These dragonflies enrich the ecosys- tems, as an important component of food webs, and their presence cer- tainly increases the aesthetic value of the landscape. The importance of protecting these extraordinary developmental habitats is crucial in context of the conservation of the odonata fauna.
  • 44. 43 1. Introduction Dragonflies (Odonata) are widespread hemi- metabolous insects. They are amphibiotic - their larvae are strong- ly associated with the aquatic environment, while adults are flying insects connected with water throughout their lives, especially during oviposition. According to the type of inhabited micro- habitat, there are two groups of dragonflies’ larvae - one living on sand or gravel as well as decomposed organic matter, and the second one being phytophiles living mainly among macrophytes. Those microhabitats are mainly found in run- ningwaters,bothnatural and anthropogenic, like rivers, streams, drain- age ditches or channels. Equally preferable are different kinds of stand- ing waters like lakes, ponds, bogs, swamps, as well as tanks in gravel pits, quarries, clay and peat excavations. But in some cases, tiny and temporary water reser- voirs, like phytotelmata seem to be enough. 2. Discussion What we call an extreme place to live is relative, but for this review the extremely challenging habitats, which require special adaptations from drag- onflies living there, were selected. Thefirstspeciesissemi- terrestrial Uropetala carovei, which inhab- its highland spring-fed bogs in New Zealand (Wolfe 1953, Corbet 1962, Silsby 2001). It drills little burrows in the seepage area, often with two openings or sev- eral ‘chambers’ on the basis (Fig.1). However, there was no case of finding more than one larva in single burrow (Wolfe 1953). Larvae live in the chambers embedded in a fine silt with their caudal plates above. The burrows are constructed in such a way as to allow water infiltration to the inside, so that they are provid- ed with the necessary moisture to breathe through their rectal gill. Therefore, Uropetala larvae can spend even several months out of the water (Wolfe 1953, Corbet 1999). That construction can take various forms, depen- dent on several factors. Firstly the larva lives just below the water level, but older instars are found at the great- er depth (Wolfe 1953). Uropetala dragonflies
  • 45. also use their burrows for hunting. They show nocturnal activity, when the entrances of their burrows are even less visible. The darkness is used to hunt for small arthropods by taking them by surprise (Wolfe 1953, Winstanley & Rowe 1980). 44 Fig. 1. The burrow of Uropetala carovei – type with several chambers (Wolfe 1953, modi- fied) Similar burrows are drilled by the other Petaluridae larvae, for example Petalura gigantea, which was described by Tillyard (1911). In addition, a few fully terrestrial species, like Hawaiian Megalagrion oahuense, are known. Its habitat is a rhi- zome mat of ferns like Dicranopteris linearis or Gleichenia sp. growing on the steep hillsides (Corbet 1962, Silsby 2001). The larvae breathe using atmo- spheric oxygen thanks to the high humidity of the air. Moreover, they have a few morpho- logical adaptations to prevent excessive loss of moisture - they are stocky and hairy, their body is strongly short- ened and their caudal lamellae are squat and thickly covered with setae (Corbet 1962). Larvae, which inhabit reservoirs peri- odically drying out, have to deal with simi- lar problems. Australian Synthemis eustalacta occupies summer-dry pools and is able to survive in shallow, dry sand up to 10 weeks without being moist- ened. After this period of time the larva is so dry that in its first con- tact with water it floats on the surface (Tillyard 1910, Corbet 1999). It is probably also caused by the structure of the hydrophobic wax cov- ering the body sur- face (Corbet 1999). However, there are not many drought-resis- tant larvae. Common adaptation for droughts is a modification of voltinism (Suhling et al. 2004, Corbet et al. 2006). Odonata often use the strategy of accelerating the devel- opment cycle in order
  • 46. 45 to emerge from the pool before drying out. It is an especially common mechanism for the sea- sonal-rainfall pools in deserts (Corbet 1999, Suhling et al. 2004). In contrast, some dragon- flies can withhold their development by the egg diapause. Indian Potamarcha congener can have the eggs in that state up to 80 days (Corbet 1999). During the temporary zone larvae often get buried in the wet sand and when the pond gets refilled by water, they continue their devel- opment (Corbet 1999, Suhling et al. 2004). Another species of this genus, Megalagrion amaurodytum (= M. koelense) breeds in the leaf axils of Astelia and Freycinetia in the wet upland forests of Hawaii, although it is able to survive with- out the water (Corbet 1962). Studies of Howarth and Watson show that M. amau- rodytum, as well as Pseudocordulia spe- cies, can even climb out if placed in free water (Corbet 1999). Williams (1936) described also other Megalagrion larvae crawling in a water-film on rocks. In many species of this genus the reduction of gills and tracheae is observed (Richards & Davies 1977). Worldwide 47 drag- onfly species are known to use phytotelmata as a larval habitat (Corbet 1999). Lyriothemis tri- color is an example of development in tree holes in India (Das et al. 2013), whereas in Borneo this is prob- ably the most impor- tant habitat in the for- est ecosystem (Corbet 1999). Water in these tanks is characterized by specific physical and chemical conditions, such as low pH, high content of dissolved solids and nutrients, and oxygen deficien- cies. Therefore, the larvae have to have high tolerance to such conditions. In addition, there are even such adaptations as canni- balism. Megaloprepus caerulatus appears to be the best example of this mechanism. Only one larva can sur- vive for 1-2 liters of water in a tree hollow (Fincke 1994, 2011). In smaller habitats the larva, which hatched first, can patrol the space, eating all newly hatched larvae (Fincke 1996, 1999, 2011). In the biggest hollows as many as 30 larvae are able to develop (Fincke 2011). This behavior provides them sooner emergence at a larger size (Fincke 2011).
  • 47. 46 Mecistogaster orna- ta larvae use a differ- ent strategy to gain the necessary quanti- ty of dissolved oxygen in tree hollow tanks – some of them live in symbiosis with algae growing on the dorsal surface of their body, including caudal lamel- lae. They face towards the sunlight, enabling the photosynthesis of the algae (de la Rosa & Ramirez-Ulate 1995, Corbet 1999). Despite the most often occupied phytotelma- ta by Odonata being Bromeliaceae tanks as well as leaf axils of other plants and tree cavities, there are also species found in even smaller water bodies, like Hadrothemis cama- rensis, which is able to develop in bamboo stamps (Corbet 1962). Obviously, many of these untypical micro- h a b i t a t s are fac- u l t a t i ve , occupied in case of lack of the more suit- able sites ( C o r b e t 1 9 6 2 , S i l s b y 2001). There are also s e v e r a l d r a g o n - flies, which ovipos- it and develop solely in ‘extreme’ habitats. The larvae of the only true marine species, Erythrodiplax berenice, is unable to develop in freshwater (Wright 1943, Smith & Smith 1996), however in lab- oratory studies they have managed to live in the tap water for one month (Smith & Smith 1996).

Optimal salinity for them is around 36-38 ppt, although they are able to live in sea water up to 260% thanks to osmoregulatory abilities (Dunson 1980). Several Odonata occupy brackish water of varying salinity – on San Salvador (the Bahamas) these ecosystems are inhabited by Erythemis sim- plicicollis, Orthemis ferruginea and Pantala flavescens (Smith & Smith 1996). Another interesting larval habi- tat is waterfalls. The best known example is the African dragonfly Zygonyx natalensis. After copula- tion, they fly in tandem through the water spray and then a female oviposits in the mats of roots, bryo- zoans or moss in the spray zone along a waterfall (Corbet 1962, Martens 1991). In Panama and Costa Rica Thaumatoneura inopina- ta shows similar behavior (Calvert 1914, Silsby 1991). These larvae are able to live on the wet vertical rocks behind rapidly falling water thanks to the dorsoventrally flat- tened body and long powerful legs with strong claws (Silsby 1991).

One of the answers is definitely lack of other convenient breeding sites. What is more impor- tant, in most of such places there are not many predators. Therefore, the adaptations to the living in extreme habitats, like high saline waters and waterfalls, are often the survival strat- egy (Calvert 1914, Corbet 1999). In p hy t o - telmata, for example, dragonfly and damselfly larvae are known to be the top predators (Fincke 1994). Furthermore, relatively large amounts of terrestrial and semi- terrestrial Megalagrion damselflies on Hawaii are most likely the result of adaptive radiation. Jordan et al. (2003) pointed out that high lev- els of endemism and species rich- ness can be correlated with islands’ ages. The emergence of the new island allowed the larvae to colo- nize the available ecological niche by developing new adaptations
  • 50. 49 and thus, many different ecological guilds were established (Jordan et al. 2003). Consequently, species of this genus inhabit equal amount of habitats as all other damselflies in the world combined (Simon 1987). Moreover, the larvae had the pos- sibility to colonize phytotelmata and terrestrial habitats due to the historical absence of mammals and ants in Hawaii (Jordan et al. 2003). Zimmerman (2001) presumes that the terrestrial Megalagrion oahuense larvae could, in the future, be an ancestor for the new order of insects, which would evolve in Hawaii. One thing is certain - the survival of these extraordinary Odonata depends in greater scale on human activity. The ecosystems inhabited by dragonflies are under strong human pressure. It affects mainly tropical habitats, which are a hotspot of dragonfly biodiver- sity. In addition, these dragonflies are an essential component of the food web in many ecosystems. Therefore, there is an urgent need for their protection.
