Scientists may have finally developed a sleeping pill that can knock you out without any weird side effects. Unlike traditional sleeping pills, which target the brain's GABA receptors, the new compound targets a totally different brain system and doesn't appear to impair cognition or memory.
When cancer cells escape into the blood, they can spread the disease throughout the body in a process called metastasis. Now, a new device called the CTC-iChip can sort through blood, detecting even a single rogue cancer cell in the bloodstream. The chip should allow doctors to catch metastasis early and potentially slow or even stop the process.
Fingerprints and DNA aren't the only things that can identify us—we also have unique "breathprints," according to a new study. These prints change throughout the day and reflect the chemical reactions going on inside our bodies. The technique could one day reveal more than just our identities and indicate drug use or even disease.
Don't blame hormones for behavioral issues. A new study shows that kids who had early onset puberty had a hard time in school and getting along with friends and as early as 4 or 5 years old, long before puberty hit. The results suggest that there are other unknown processes at play.
The controversial and hugely expensive Alpha Magnetic Spectrometer (AMS) aboard the International Space Station has detected an excess of antiparticles in space, a possible sign of dark matter. But scientists caution that the results may have a more mundane explanation. As AMS continues its work, some are wondering if it will indeed be possible to accurately identify the source of the antiparticle excess and thus confirm the existence of dark matter.
With thousands of unexplained dead pigs found floating in rivers and two confirmed deaths from a new bird flu strain, it's no wonder that rumors have been flying in China. So far, only one other person has been confirmed infected with H7N9 virus, and researchers say that the pig deaths, though mysterious, are likely unrelated.
