ISRO Receives Gandhi Peace Prize 2014

The President, Shri Pranab Mukherjee, presented the "Gandhi Peace Prize 2014" to Indian Space Research Organisation (ISRO) in recognition of its services in transforming India through the use of space technology and space based services, at a special ceremony in Rashtrapati Bhavan.

The "Gandhi Peace Prize" for social, economic and political transformation through nonviolence was instituted in the year 1995 on the occasion of the 125th Birth Anniversary of Mahatma Gandhi as a tribute to his ideals.
Gandhi Peace Prize is presented annually by the President.

Hello friends,
So here's a new breakthrough thought that might interest you..
We all know that reliable data storage for future (especially important data) is a rising concern as the devices we have now need contraction in size for huge data around the globe and these devices have reliability for around 50 years only..
So, WHAT AFTER THAT ??

Now,we know that DNA contains and stores our genetic information.
THE IDEA:- Can we use DNA to store our huge data which can longlast thousands of years reliably ??
So,let us find it's answer by work of these scientists..
----------------------------------------------------------------------------------------------
What is DNA in brief ??
DNA or deoxyribonucleic acid is a long molecule that contains our unique genetic code or our genetic information. Like a recipe book it holds the instructions for making all the proteins in our bodies.

“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,” says Grass, who is with ETH Zurich.
“On a hard drive, we use 0s and 1s to represent data, and in DNA, we have four nucleotides A, C, T and G.”

ADVANTAGES of this technology OVER hard drives: size and durability. An external hard drive about the size of a paperback book can back up five terabytes of information and might last 50 years.
*In theory, a fraction of an ounce of DNA could store more than 300,000 terabytes. And, from archaeological finds, scientists know that DNA from hundreds of thousands of years ago can still be sequenced today.

RESEARCH WORK:-
A handful of research groups are exploring methods to take advantage of DNA’s storage potential.
Grass’ team has encoded DNA with 83 kb of text from the Swiss Federal Charter from 1291 and the Method of Archimedes from the 10th century. They encapsulated the DNA in silica spheres and warmed it to nearly 160 degrees Fahrenheit for one week, which is the equivalent of keeping it for 2,000 years at about 50 degrees. When they decoded it, it was error-free.

CHALLENGES FOR THIS TECH:-
1) Very costly
2) Absence of Data navigation and browsing capability on DNA.

FUTURE:-
Once it's need arises from both scientific community and user's side, it's drawbacks will be worked upon and we'll enter in a new era of infinite storage capabilities.

How to preserve fleeting digital information with DNA for future generations Robert N. Grass, Ph.D. ETH Zurich Hand-written letters and printed photos seem quaint in today’s digital age. But there’s one thing that traditional media ha...

A new scientific instrument promises to capture some of nature's speediest processes.
It uses a method known as ultrafast electron diffraction (UED) and can reveal motions of electrons and atomic nuclei within molecules that take place in less than a tenth of a trillionth of a second -- information that will benefit groundbreaking research in materials science, chemistry and biology.
----------------------------------------------------------------------------------------------
But how can scientists actually catch a glimpse of the interior of materials with particles like electrons?

ANSWER:- The method works because particles have a second nature: They also behave like waves.
When electron waves pass through a sample, they scatter off the sample's atomic nuclei and electrons. The scattered waves then combine to form a so-called diffraction pattern picked up by a detector.
The whole apparatus works like a high-speed camera, capturing differences in diffraction patterns over time that scientists use to reconstruct the sample's inner structure and how it changes.

IT'S FUTURE:- Ultrafast Electron Microscope
USE:-These advances could be used to investigate how ultrafast motions in tiny regions of materials are linked to magnetism and other material properties.

*Now this is how drawbacks or adverse effects of a system can be used as a solution to problems created by them.*

------------------------------------------------------------------------------------------------------

When hypersonic vehicles like spacecraft zips along at five or more times the speed of sound towards earth's atmosphere, an envelope of hot ionized air, called a plasma sheath, surrounds it.
This plasma sheath will reflect electromagnetic signals under most conditions, cutting off connection with anything outside of the vehicle leading to 'COMMUNICATION BLACKOUT' between earth station and spacecraft.

NOW THE IDEA:-However, under certain special conditions, a plasma sheath can actually enhance the radiation from a communication antenna.

They propose adding a "matched layer" to ordinary communication antennas to create the desired resonant conditions during normal hypersonic flight.

The matched layer works because it acts as like a capacitor -- a type of electrical energy storage unit -- in the antenna circuit, Gao explained.
The plasma sheath, on the other hand, acts like an inductor, which resists changes in an electric current passing through it. When a capacitor and an inductor are paired together, they can form a resonant circuit.

"Once the resonance is reached, the energy can be exchanged between them steadily and losslessly, like real capacitance and inductance do in a circuit," Gao said.

"As a result, the electromagnetic radiation can propagate through the matched layer and the plasma sheath like they do not exist."

Communicating with hypersonic vehicles in flight Routine communications blackouts, between a re-entry spacecraft and ground control, can cause anxiety, as there is no way to know or control the location and state of the spacecraft from the ground, but researchers have now proposed a new way to maintain communication with spacecraft as they re-ente…
