I spoke on "Big Data in Biology". The talk basically concentrates on how biology has affected big data and how big data has become a key player in biology. I have also covered how DNA storage can address long term archival storage.
● The data produced by the social
media in a single minute is
● All this data is stored and
analyzed for many obvious
● DNA carries all the genetic information
in our body.
● It drives the human body.
● Genome is an organism’s complete set
● It is an international scientific research project.
● The goal of the project is to determine the sequence of chemical base
pairs that make up human DNA.
● The project was successfully completed in 2003 and 90% of the human
genome was sequenced.
● This was just a start of a new era of sequencing.

Clouds are a solution, but they also throw up fresh challenges. Ironically, their proliferation
can cause a bottleneck if data end up parked on several clouds and thus still need to
be moved to be shared.
And clouds means entrusting valuable data to a distant service provider who may be
subject to power changes or other disruptions.
Scientists experiment with different constellations to suit their needs and trust levels.
Clouds can be used for both data storage and computing.
This reduces the overhead of transferring the data into a local machine and computing it on
● The information necessary to build and control any living organism is written in its
genome and it took 13 years to decipher.
● A single decade later sequencing a genome takes a few hours on a machine that fits on
● The tsunami of biological data generates new problems, it needs to be analysed
properly to unearth and retrieve the exciting knowledge it contains.
● Getting the most from the data requires interpreting them in light of all the relevant prior
● That means scientists have to store a large data sets, and analyse, compare and share
them - not simple tasks.
It is estimated that by 2025 , exabytes(1018) of genomics data will be produced globally
and will far exceed from twitter and facebook.
Moreover, the genomics data being produced roughly doubles every year and will
require new solutions in precision and accuracy for storage, analysis and sharing.
The European Bioinformatics Institute(EBI), UK, part of the European Molecular Biology
Laboratory and one of the world’s largest biology-data repositories, currently stores
20 petabytes(20*1015) of data and back-ups about genes, proteins and small
Genomic data accounts for 2 petabytes of that, a number that more than doubles every
Microsoft has already started storing some of its data using DNA.
The first phase of demonstration was successfully completed.
Microsoft partnered with the startup “Twist Bioscience” which produced oligonucleotides for
them and arranged them in the sequence specified.
One of the drawbacks of this storage is it cannot be commercialised.
