Saber-toothed cats may be best known for their supersized canines, but they also had exceptionally strong forelimbs for pinning prey before delivering the fatal bite, says a new study.

New research shows that people with Alzheimer’s disease who have large heads have better memory and thinking skills than those with the disease who have smaller heads, even when they have the same amount of brain cell death due to the disease.

Physicists have been studying the Aharonov-Bohm effect — the interaction between electrically charged particles and magnetic fields — and how it relates to carbon nanotubes. While doing so, they came to the unexpected conclusion that magnetic fields can turn highly conductive nanotubes into semiconductors.
The efficacy of preimplantation genetic screening (PGS) has been one of the most hotly disputed subjects in assisted reproduction over the past few years. A new study has now shown, in its groundbreaking proof of principle study, that screening of polar bodies (small cells that are the by-product of egg development), is a reliable method [...]
Rearing juvenile salmon at the relatively high temperature of 16 C causes skeletal deformities in the fish. Researchers investigated both the magnitude and mechanisms of this effect, which occurs when salmon farmers use warmed water to increase fish growth rates.
It is predicted that 80 percent of active Internet consumers and Fortune 500 companies will have an avatar or presence in a virtual community, including social networks, by the end of 2011. A new article investigates the role avatars play in the virtual and consumer environment, how well avatars reflect the personality of their creators, [...]

The minute brains of flies process visual movements in only fractions of a second. Just how the brain of the fly manages to perceive motion with such speed and precision is predicted quite accurately by a mathematical model.
Nutrition experts have essentially “cured” laboratory mice of mild, diet-induced diabetes by stimulating the production of a particular enzyme.
