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

Maybe this study explains the action of Vick's Vapor Rub or the eucalyptus oil ingredient.
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.
You can eat kudzu leaves as salad or boiled greens. Goats will eat it as well.
Hearing that a 16 year old had found a supernova she pronounced "I could beat her".
Get a grip, it's only been about 400 years since the last turnover.
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.

The president of Harvard was changed for ignoring this equality.
"Spock, did you see the looks on their faces?" "Yes, Captain, a sort of vacant contentment."
