The scientist reports that MicroRNAs control gene expression in a single-celled alga Chlamydomonas reinhardtii the first single-celled organism in which microRNAs have been discovered.
I had mentioned earlier a number websites, that offer scientific videos
though many researchers have their own restriants when it comes to using technology whetehr it is open source or peer reviewd journal or blogs itself. Perhaps groups was the only social content driven concept that got off the ground when it comes to science and especially life science
but that certainly doesnt seem to deter more people coming up with new site that offer more web2.0 services to scientists
this time the new kid on the blck is http://www.labaction.com another science video sharing website
for more information on similar services and technology see my earlier posts
I was looking for an easy way to explain DNA, Gene splicing, SNP, Jumping genes, Transposons and such to a non biologist without using too much technical jargons. And then I came across a study by University of Cambridge about how human mind reacts and learns written text , JUst see if you can read the following text, They are sure not spelling mistkes but made by rearranging text in word by retaining the first and last letter in such a way that your mind still can read it
*I CAN READ IT! CAN YOU*
Cna yuo raed tihs? fi yuo cna raed tihs, yuo hvae a mnid to udrtsand DNA and why it is poisbssle for DNA to Evovle.
i cdnuolt blveiee taht I cluod aulaclty uesdnatnrd waht I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde inervtisy, it dseno’t mtaetr in waht oerdr the ltteres in a wrod are, the lny iproamtnt tihng is taht the frsit and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it whotuit a pboerlm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Azanmig huh? yaeh and I awlyas tghuhot slpeling was ipmorantt! now you can raed tihs
Did you read the text and were you able to understand the meaning and the message it contained, If so think about it if you can read the message even when the order at which it is written is changed, Our DNA is also evolving in a similar fashion,now go on read about Gene splicing, SNP, Jumping genes, Transposons you would understand them better.
I guess perhaps we can use the same to explain to students or non biologists many other features of DNA especially how it is possible for HSP genes to create different proteins from different structural arrangement or how more than one DNA can code for one protein

Another science website that seems to be as taking its cues from web2.0 anthology.
Faculty of 1000 Biology is the next generation literature awareness tool. It is a revolutionary new online research service that will comprehensively and systematically highlight and review the most interesting papers published in the biological sciences, based on the recommendations of a faculty of well over 1000 selected leading researchers.
Faculty of 1000 Biology will be run by scientists for scientists, and will provide a rapidly updated consensus map of the important papers and trends across biology.
Each Faculty is subdivided into 3-12 Sections, each run by two or three Section Heads and comprising between 10 and 50 Faculty Members. Faculty of 1000 Biology aims to invite the best scientists internationally in each field and to involve both experienced and younger investigators.
All in all an excellent website with lots of information which is peer reviewed
I would like to introduce you newly found SCIENTIFIC VIDEO site which
is www.DnaTube.com the scientific video site
In this site, you can upload and share your scientific videos, watch videos, experminets, animations and many otherinformation about biology, chemistry.
Thats not really a big surprise considering he himself is a scientist, Dr. Abdul Kalam Azad the President of India who is also the commander in chief of the Army,Navy and Airforce of India, and is key force for India’s nuclear and Space power and technology uses, yahoo answer so that he can listen and hear from his people, so what about our scientist ! especially in life sciencs and academicians. Recently I had posted about the similar attempts by US presidentail hopeful’s sudden rush to web2.0. and how youtube is helping the science
Dr. Kalam’s His thought provoking question, has garnered over 28000 answers in just 30 days. wow thats a response rate you could never expect in any other online forum asking for soutions to a scientific question or problem
chekout more visit his profile at http://in.answers.yahoo.com/my/profile?show=1e6b7ca835ee0cc4185b0ab950476c08aa
Some leading Indian figures like Sri Sri Ravishankar, Kiran Bedi, and Leander Paes have posted answers to Dr. Kalam’s question
less than 10% of people build content in an online community — in this case answer questions. The popular thumb-rule for online participation is 1% visitors would be hard-core contributors, 10% mild contributors, and 90% would be beneficiaries

Biotechnological methods can be used for cryptography. Here two different cryptographic approaches based on DNA binary strands are shown. The rst approach shows how DNA binary strands can be used for steganography to provide rapid encryption and decryption. It is shown that DNA steganogra- phy based on DNA binary strands is secure under the assumption that an interceptor has the same technological capabilities as sender and receiver of encrypted messages. The second approach shown here is based on steganography and a method of graphical subtraction of binary gel-images. It can be used to constitute a molecular checksum and can be combined with the rst approach to support encryption.
