Scientists have long known that the human body runs like clockwork, guided by a circadian system that responds to daily patterns of light and darkness. Now a team of researchers is developing a personal device to measure daily light intake and activity, which could allow them to predict optimal timing for light therapy to synchronize the circadian clock to the 24-hour solar day and relieve psychosocial stress.

A nanotechnology developed by a University at Buffalo professor has enabled researchers to identify a molecular signature common to both familial and sporadic cases of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease. It is the first time that a common molecular signature has been found in patients with both familial and sporadic cases, where no other family members have the disease, of ALS.

E-voting firms aren't having a particularly good week. Just days after research commissioned by the state of California showed vulnerabilities in many e-voting systems, a study commissioned by the state of Florida found serious security issues with Diebold's optical scan technology. While the article suggests that this is one of the first times the security has been questioned on optical scan machines (where there is still a paper trail, but these machines are used for counting the votes), there have actually been numerous studies pointing out the problems with Diebold's optical scanners, and how they can easily be hacked. Of course, what's amusing here is that some of the first tests that found the problems with Diebold's optical scanners were done two years ago by a "rogue" elections official in Florida. Of course, back then, the state of Florida didn't launch an immediate investigation. The state hung the elections official, Ion Sancho, out to dry, as the e-voting companies cracked jokes about the vulnerability and teamed up to conspire against him. So, now, years later, we find out that the security vulnerabilities he pointed out then are actually there is anyone apologizing? Doesn't sound like it. In fact, it sounds like Florida politicians are downplaying the security problems with these machines.

When using gestures to get their points across, orangutans rely on the same basic strategy that humans follow when playing the popular game and intentionally modify or repeat hand (or other) signals based on the success or failure of their first attempt.
