The Stardust mission, launched in February, will be the first mission since Apollo to return samples of space material to Earth for analysis. The spacecraft will encounter Wild 2, a comet that alters course among the inner planets, and trap small particles from its coma.
Scientists have created a synthetic peptide that blocks the formation of amyloid plaques in the brain, destroying existing plaques and preventing nerve cell death. This breakthrough may lead to a new therapy for Alzheimer's disease and other diseases caused by defective protein folding.
A panel of scientists concludes that some UFO sightings are accompanied by physical evidence deserving scientific study. While the panel was not convinced of an extraterrestrial explanation, it highlighted potential health risks and noted that rare natural phenomena can cause similar effects.
A team of researchers led by Dr. Joel Bennett has successfully developed a new technique to study the IIb/IIIa receptor, a key player in platelet aggregation. This breakthrough could pave the way for the creation of more potent anti-clotting drugs.
Research finds that voluntary HIV counseling and testing significantly reduce risk behaviors, including unprotected sex, in individuals and couples. The study, conducted in three developing countries, shows a 50% reduction in risk behavior among participants who received counseling and testing compared to those receiving standard healt...
University of Pittsburgh researchers discover that boosting CD8 T cells, also known as killer T cells, can establish long-term immunity against HIV-1. By treating dendritic cells with HIV-1 proteins and interleukin-12, the immune system can be trained to recognize and attack infected cells.
A multi-center study provides clear guidelines for genetic testing in women with breast cancer, identifying those at high risk of ovarian cancer. The study found that nearly 40% of participants had abnormalities in BRCA1 and BRCA2 genes, associated with a 10-fold increase in ovarian cancer risk.
