From the abstract, it's a Calcium-activated Potassium channel (BK) that leads to the smooth muscle relaxation.

agonist > TAS2R (a GPCR) > Gaq > plB > IP3 > ^Ca++ > open BK > hyperpolarization > close voltage-sensitive CaV channels > relaxation

Maybe this study explains the action of Vick's Vapor Rub or the eucalyptus oil ingredient.

Comment Re:Should read: Low res grainy 2D video (Score 1) 207

The 3-D video is still in Texas. Actually they probably haven't assembled it into a "glasses version". They are probably planning to let users "focus through" and select their z-depth and see the section there. They could also allow viewing from any angle. The voxels are all in the computer, they haven't hired on the producer to make the fancy version. The viewer has to be sitting at their computer choosing the POV and depth.

Resolution here refers to the distance between two resolvable features in the specimen, not the height of the viewing screen. They claimed it to be 6 micrometers, I'd guess that refers to all three directions. The whole heart sac is about 0.2 mm across so they have about 30 "grains" across the heart. Going to 4 micrometers in the z direction should be easy, just an expensive commercial laser upgrade. Going to 2 or better in the x-y direction depends on scanners, the a-d rate and the ability to dump it into ram. I don't think anyone is doing 2 micrometer z-resolved OCT.

Submission + - WHO declares H1N1 pandemic

juggledean writes: "The World Health Organization (WHO) has declared a global flu pandemic after holding an emergency meeting, according to reports.

It means the swine flu virus is spreading in at least two regions of the world with rising cases being seen in the UK, Australia, Japan and Chile. http://news.bbc.co.uk/2/hi/health/8094655.stm

"...there were people who believed we might be in a kind of apocalyptic situation and what we're really seeing now with H1N1 is that in most cases the disease is self-limiting,"

It will be interesting to see how the security community reacts."

Comment It will get worse (Score 1) 163

There is a company Academic Analytics http://www.academicanalytics.com/ that, for a price, will search the web and provide rankings to "help" Deans and Boards of Trustees to evaluate their graduate programs. The "better" programs have all ready been accused of search engine optimization. I guess it could also be seen as an opportunity.

At least with US&WR we all know how much they know about quality.

From the abstract "The gender gap has significantly narrowed over time in the U.S. and is not found among some ethnic groups and in some nations ... It correlates with several measures of gender inequality. Thus, it is largely an artifact of changeable sociocultural factors, not immutable, innate biological differences between the sexes." http://www.pnas.org/content/early/2009/06/01/0901265106.abstract The president of Harvard was changed for ignoring this equality.
