In a Data storage breakthrough scientists have figured out how to save massive quantities of
information in a single molecule of DNA, which will store the data
safely for up to 1 million year The breakthrough could lead to digital archives of everything from
ancient texts to Wikipedia changes being stored in the form of DNA that
could in theory survive for hundreds of thousands of years without any
loss of data.
Genetic
information stored in DNA molecules makes life on Earth possible, but
what if humans could use the same kind of technology to store their own
data? Apparently, scientists have figured out how to save
massive quantities of information in a single molecule of DNA, which
will store the data safely for up to 1 million years.
The Swiss Federal Institute of Technology has “fossilized” DNA by encapsulating it in glass, to prolong the life of DNA that would store data. The
scientists also came up with a mathematical algorithm that lets them
decipher data written in DNA code. scientists are using the way DNA is built to store information. DNA is
based on sequences of four chemical building blocks, referred to as A,
C, T, and G, which are used to code information. Dr Grass said that his team has converted 83 kilobytes of text from the
medieval Swiss Federal Charter of 1291 and the Methods of Archimedes
from the 10th Century into the digital code of DNA based on sequences of
four chemical building blocks, the nucleotides A, C, T and G.
“A
little after the discovery of the double helix architecture of DNA,
people figured out that the coding language of nature is very similar to
the binary language we use in computers,” Dr. Robert Grass said. “On a
hard drive, we use zeros and ones to represent data, and in DNA we have
four nucleotides, A, C, T and G.”
Scientists
used a machine to synthesize DNA molecules, and they were heated to 71C
for a week, or the equivalent of being stored at 50C for 2,000 years.
An
ounce of DNA can fit on a penny, storing 300,000
terabytes of memory that can survive for up to 1 million years.
Comparatively, an external hard drive with a capacity of a few terabytes
can only last for up to 50 years.
The
problem with this discovery is that there’s no affordable way of
turning it into a commercial product just yet. Furthermore, reading
information from a DNA drive isn’t user-friendly. You could read the
entire thing, but you can’t pinpoint the location of individual data
blocks stored in DNA. That’s the next challenge for the Swiss team.
“Right
now, we can only read everything that’s in the drop. But I can’t point
to a specific place within the drop and read only one file,” Grass said.
just 1 gram of DNA is theoretically capable of holding 455
exabytes - enough for all the data held by Google, Facebook and every
other major tech company, with room to spare. It's also incredibly durable.
Everything from ancient texts to Wikipedia changes could be archived.

Bacteria are the most plentiful living organism on the Earth.They are the most smallest organism ,each consisting of a simple , single cell.A few types of bacteria ,called germs ,cause diseases in humans .But most bacteria are harmless, some are very useful.They used in making drugs and foods. Bacteria reproduce by binary fission(splitting in two). Reproduction by division means that bacteria can multiply very quickly,if the conditions...
