RNAi scoops the Nobel

Andy Fire (now at Stanford) and Craig Mello (of the University of Massachusetts Medical School) are newly minted Nobel laureates. Just a few years back, they discovered a process called RNA interference ('RNAi') in the nematode worm C. elegans. Nature (free link) sums it up best:

RNAi, which occurs naturally in plants and animals, allows a gene to be specifically 'silenced'. This helps to regulate gene expression, and protects against viral infection and 'jumping genes' that can replicate and spread through the genome.

The process can also be induced experimentally by injecting tailor-made genetic sequences into cells, giving scientists a method for deliberately silencing a target gene. The method is now widely used as a basic genetic tool and is a promising candidate for future therapies.

These guys deserve it, and everybody knew they'd eventually win it. Personally, I'm still a little surprised some GFP folks haven't won yet (Roger Tsien, Douglas Prasher, Marty Chalfie). GFP is used everywhere, and some might argue that it has yielded more biological insights than has RNAi. Still, the RNAi guys did some great science, and I'm glad to see them win.

UPDATE: Aggie prof Jim Hu photoblogs the press conference at Stanford for Andy Fire. Nice work.

UPDATE: Of course, Berkeley is quick to note that Fire is a Berkeley alumn.

I find your blog very interesting and healthy. I read almost all articles in this category. Thank you for sharing your valuable time

I really enjoyed this great post and you are very talented and interesting. I really appreciate this excellent post.

A thoughtful insight and ideas I will use on my website. You've obviously spent a lot of time on this. Well done!

Meanwhile, Jason Wu is the next designer to partner with Target. His collection will be available in stores and online as of February 5, 2012.hongxinmaoyi114post.

If Missoni does collaborate with Macy's, the label will be following in the footsteps of designers including Karl Lagerfeld hongxinmaoyi114post.

"We have a lot of options because everyone is interested, but it has to be something that touches different categories…. The fact that you can put a zigzag on anything was part of the success at Target. People who wouldn’t wear a top would have a glass or a blanket.hongxinmaoyi114post.

Thanks a lot for sharing this amazing knowledge with us. This site is fantastic. I always find great knowledge from it.

Wow, nice post,there are many person searching about that now they will find enough resources by your post.Thank you for sharing to us.Please one more post about that..

n searching about that now they will find enough resources by your post.Thank you for sharing to us.Please one more

Great things are not done by impulse, but by a series of small things brought together.

Whatever is worth doing is worth doing well.

So this is what happened with me, anyways its a good effort, I appreciate it. Thanks

Worth sharing this with all

Let us face the reality, so that we are committed to our ideal.Some people want it to happen, some wish it would happen, others make it happen.

Don't worry too much about the ambiguous future, just make effort for explicit being present. We are what we repeatedly do. Excellence, then, is not an act, but a habit.

I also think so,Do you think the best in the webnet too? there were a good web for, you don't like, Never mind, much more:if you like, you can see
