50k GB DVD!

Professor V Renugopalakrishnan of the Harvard Medical School in Boston claims to have developed a layer of protein made from genetically altered, light-sensitive microbe proteins which could store up to 50K GB or 50 terabytes. The light-activated protein, found in Halobacterium salinarum membrane, is also known as bacteriorhodopsin (bR). It captures and stores sunlight and converts it to chemical energy. When light shines on bR, it is converted to a series of intermediate molecules each with a unique shape and colour before returning to its 'ground state'.

By modifying the DNA that produces the bR protein, Prof Renugopalakrishnan and his colleagues were able to produce an intermediate that normally last for a few days to lasts for more than several years. They also engineered the bR protein to be more stable at the high temperatures generated by storing terabytes of data. They said the new technology will ultimately pave the way for a binary system to store data. "What this will do eventually is eliminate the need for hard drive memory completely," said Renugopalakrishnan.

Prof Renugopalakrishnan believes the protein layer could allow DVDs and other external devices to store terabytes of information.The new protein-based DVD will have advantages over current optical storage devices including next-gen DVD wannabe Bluray and HD-DVD because the information is stored in proteins that are only a few nanometres across.

"The protein-based DVDs will be able to store at least 20 times more than the Blue-ray and eventually even up to 50,000 gigabytes (about 50 terabytes) of information. You can pack literally thousands and thousands of those proteins on a media like a DVD, a CD or a film or whatever," he said at the International Conference on Nanoscience and Nanotechnology in Brisbane.

I wish I had a 50GB DVD... :D

shaon u got the thing wrong... its 50k GB which means 50teraByte DVD...1000 times larger than u wanted is expected to be available...:D

Dipu Nobody said...

50 TB DVD te ki thakte pare .. umm .. 50K 100 min. lenght vdo (rated -x)clip :P he he he ... yummy :D

tobe joto jai kos .. protein dia data storing .. sei rokom bepar separ .. ustaad manush !

aragorn said...

dipu eto boro collection korte gele 50k shuvor moto dedicated lok lagbe... ;))

nalumoni said...

more space to store my pics in!

50 wataByte?! I've never even heard of TeraBytes! However, I'm sure those DVD's will cost a lot, but if they're protein based or whatevr then maybe the price will go down to like 99cents! Whooppeee!

aragorn said...

nowal, u will need to snap ur pics all through ur lifetime to complete the dvd...:P...

BFOB... Tera= 1000 X Giga... Tera is also a mathematical term like giga...to make it more clear
1000 kilo = 1 Mega
1000 Mega = 1 Giga
1000 Giga = 1 Tera...
[feelin like teacher now...heh heh] and they sure will be cheap within years...:D

kier Tera .. I am dreaming for PetaByte .. :P

yeah Tareq Shuvo o pechgite poira jaibo etto hoile :O

our physics teacher made us memorize the prefixes on the very first day :D pe,te,gi,me,ki and fe,pi,na,ma,mi ... i don't know if u guys did that.. but this thing was like a trademark of Mintu sir's students :D ...

newho... when I started reading this article i thought they have made a high energy storing protein that you could inject in your body or something ... but then... my hope to get stronger got smashed *sniff*

50 TB DVD! man.. if i had one of those i would've thrown my stupid external {can't make it work :((} off the balcony right now!

audity one day ur dream about becoming stronger might come true.... addsense ta off korte hobe... kintu kotha korbo mone nai...:S
