Scientists decode DNA of pig, a research favorite - http://news.yahoo.com/s...
A.T., Fajar Nurdiansyah and Ruchira S. Datta liked this
"An international group of scientists has decoded the DNA of the domestic pig, research that may one day prove useful in finding new treatments for both pigs and people, and perhaps aid in efforts for a new swine flu vaccine for pigs. Pigs and humans are similar in size and makeup, and swine are often used in human research. Scientists say they rely on pigs to study everything from obesity and heart disease to skin disorders."

Pretty pictures but slight misunderstanding in the original blog post which didn't realize that the electron micrographs are false-colour images. Some of the plate images also look somewhat "enhanced" too.

Yes, I guess the blogger was just interested in the pretty colours, no matter if these were real or enhanced. Nice images, anyway...

The 2009 Nobel Prize in Physiology or Medicine has been awarded for the discovery "how chromosomes are protected by telomeres and the enzyme telomerase" published in 1982. It was not mentioned that the theory of telomere shortening was published a decade before by Olovnikov http://www.youtube.com/watch...

interesting & who is the person behind 'reflection'? Maybe that person knows Olovnikov himself. http://en.wikipedia.org/wiki...
- Attila Csordas
Is not it strange, that a person who is well-known as the author of the telomere theory is not even mentioned? He was nominated for the Nobel prize as well, so he could have been at least acknowledged. It means that doing theory is not rewarding?
- reflection
Agreed, this is strange. But it is typical of the Nobel process, which wants to make superstars and doesn't have much to do with actual science, and so it ignores the complex connections that actually drive discovery. Look at the Chemistry prize for "discovery of GFP" that went to three people OTHER than the actual discoverer.
- Bill Hooker
IMHO, Nobels should be granted for sustained and conclusive work in a field, so personally, I think they got it right... http://www.ncbi.nlm.nih.gov/sites...]

- Jason Winget
Bill, but I associate GFP with those other three people who really brought that to fruition. That's fine by me. In other words I agree with Andrew
- Deepak Singh
Actually I'm not even right about who *discovered* GFP... Shimomura found the protein, 20 years later Prasher cloned the gene. I still think Prasher got ripped off though, since it was only a couple of years after he made the clone available that it started to be widely used as a tag, whereas the protein was known for 20 years before that and no one could do anything with it. Not that...

I am thinking about the 1962 Nobel prize for the discovery of the molecular structure of DNA. The prize was awarded to the people who did theory. But that seems to be the only exception. Other than that, all prizes were awarded to the experimentalists.
- reflection
Also remember that it took till 1962 to award the prize because otherwise there would have been four. The issues over that were only resolved when Rosalind Franklin died because the prize is never given posthomously. In the case of DNA you might argue that Wilkins was the experimentalist of course
- Cameron Neylon
Interesting... from the book of Stephen S. Hall: "Cell paper confirmed the existence of telomerase and opened the door to one of the most productive areas of research in modern cell biology. It also confirmed Olovnikov's original hypotheses, but his train stil didn't arrive at the station, because Blackburn and Greider failed to mention his earlier theoretical work in their paper. "We...

"typical of the Nobel process, which wants to make superstars and doesn't have much to do with actual science".....hmmm......interesting perspective. Anyway, while discussing who was left out because of the three rule, S. Moncada is a recent one (NO).
- Maxine
Maxine, my take on this is, the people who got it usually deserved it, and we should begrudge them their efforts. What we need to make sure is that deserving folks don't get left out. The three rule is tough one especially when big science comes into play.
- Deepak Singh
Just as well science isn't literature or "peace" (aka politics!), where far more subjective elements come into play and the emotional reactions to the prizewinners seem to be far more extreme.

Science ponders 'zombie attack' (BBC News) - or modelling of an outbreak of "an unusual infection" - http://news.bbc.co.uk/2...
"If zombies actually existed, an attack by them would lead to the collapse of civilisation unless dealt with quickly and aggressively. That is the conclusion of a mathematical exercise carried out by researchers in Canada. In some respects, a zombie "plague" resembles a lethal, rapidly spreading infection. The researchers say the exercise could help scientists model the spread of unfamiliar diseases through human populations." (Scientific article downloadable under "Related internet links")

Computer models of response strategies to epidemics show that strategies are more effective in dense population centers than in rural a areas. http://www.eurekalert.org/pub_rel... #mathbio
Not only does their research show that rural residents may be more likely to maintain normal levels of social contact than urban residents, but the researchers said that the decreased access to hospitals and physicians also make rural areas especially vulnerable during an epidemic. Access to and propensity to use reliable and advanced communication technology is also an issue.
