Geekbench is great and all, but we want to know what really matters!
Submission + - Researchers accidentally discover how to turn off skin aging gene
BarbaraHudson writes: While exploring the effects of the protein-degrading enzyme Granzyme B on blood vessels during heart attacks, professor David Granville and other researchers at the University of British Columbia couldn’t help noticing that mice engineered to lack the enzyme had beautiful skin at the end of the experiment, while normal mice showed signs of age. The discovery pushed Granville’s research in an unexpected new direction.
The researchers built a mechanized rodent tanning salon and exposed mice engineered to lack the enzyme and normal mice to UV light three times a week for 20 weeks, enough to cause redness, but not to burn. At the end of the experiment, the engineered mice still had smooth, unblemished skin, while the normal mice were deeply wrinkled.
Granville is also continuing to examine the effects of Granzyme B on aneurysms, especially of the aorta, the largest blood vessel in the human body. "When we inhibit Granzyme B in that model we can affect the collagen organization and strength of collagen in the aorta and prevent rupturing".

Submission + - A New Law For Superconductors (mit.edu)
TaleSlinger writes: MIT researchers have discovered a new mathematical relationship — between material thickness, temperature, and electrical resistance — that appears to hold in all superconductors. They describe their findings in the latest issue of Physical Review B.
The result could shed light on the nature of superconductivity and could also lead to better-engineered superconducting circuits for applications like quantum computing and ultralow-power computing.
“We were able to use this knowledge to make larger-area devices, which were not really possible to do previously, and the yield of the devices increased significantly,” says Yachin Ivry, a postdoc in MIT’s Research Laboratory of Electronics, and the first author on the paper.
“None of the admitted theory up to now explains with such a broad class of materials the relation of critical temperature with sheet resistance and thickness,” says Claude Chapelier, a superconductivity researcher at France’s Alternative Energies and Atomic Energy Commission. “There are several models that do not predict the same things.”
Chapelier says he would like to see a theoretical explanation for that relationship. But in the meantime, “this is very convenient for technical applications,” he says, “because there is a lot of spreading of the results, and nobody knows whether they will get good films for superconducting devices. By putting a material into this law, you know already whether it’s a good superconducting film or not.”

Submission + - Spacecraft spots probable waves on Titan's seas (sciencemag.org)
sciencehabit writes: It’s springtime on Titan, Saturn’s giant and frigid moon, and the action on its hydrocarbon seas seems to be heating up. Near the moon’s north pole, there is growing evidence for waves on three different seas, scientists reported here today at a meeting of the American Geophysical Union. Researchers are also coming up with the first estimates for the volume and composition of the seas. The bodies of water appear to be made mostly of methane, and not mostly ethane as previously thought. And they are deep: Ligeia Mare, the second biggest sea with an area larger than Lake Superior, could contain 55 times Earth’s oil reserves.
