A second-generation experimental anti-obesity and diabetes drug has shown promise in reducing body weight in rodents just as effectively as the predecessor rimonabant while avoiding the risk of psychiatric side effects that led to the withdrawal of rimonabant from the market and stopped further development of other brain-penetrating drugs of its type.

Biomolecular engineers have developed technology to artificially create spider dragline silk proteins that can be used to make ultra-strong synthetic fibers and bulletproof vests.

Scientists have shown that a variant form of a fluorescent protein originally isolated from a reef coral has excellent properties as a marker protein for super-resolution microscopy in live cells.

In Germany, several national health campaigns promote cancer screening by announcing that only one in five German men gets screened. This is supposed to motivate men to have an examination. But a new study finds that this well-meaning message has the exact opposite effect: it makes men less likely to choose to get screened.

Quantum cryptography is the safest way to encrypt data. It utilizes the fact that transmitted information can only be measured with a strictly limited degree of precision. Scientists have now discovered how the use of a quantum memory affects this uncertainty.

Advances in antiretroviral treatment have shown that the progressive immune system destruction caused by HIV infection, including AIDS, can be prevented, indicating the importance of beginning ART early, when a person with HIV infection is without symptoms, according to the 2010 recommendations of the International AIDS Society-USA Panel.

It was just a colour out of space--a frightful messenger from unformed realms of infinity beyond all Nature as we know it; from realms whose mere existence stuns the brain and numbs us with the black extra-cosmic gulfs it throws open before our frenzied eyes. [More]

Even in better neighborhoods, parents should be wary about letting teens gather with nothing to do and with no adult supervision, a new study suggests. In a long-term study of Chicago neighborhoods, researchers found that informal teen gatherings significantly increased the likelihood of violent behavior by the adolescents.

A treatment plan used to prevent potentially dangerous blood clots in recovering surgical patients can also benefit some patients immobilized by acute medical illness, doctors have found in a multi-institutional study.
