Researchers have discovered compounds in the bark of the pawpaw tree that show preliminary success in fighting some drug-resistant cancers. The compounds, called Annonaceous acetogenins, preferentially kill multidrug-resistant cells by inhibiting ATP production, pulling the plug on their energy source.
The Mars Global Surveyor mission will spend nearly two years collecting data as it maps Mars' surface and atmosphere. The spacecraft will use aerobraking to trim its path around the planet, allowing for a global portrait of Mars' topography, mineral composition, and interior.
A new study has uncovered the genetic wiring diagram underlying Candida's infectiousness, revealing two parallel genetic pathways that account for its ability to filament. Inactivating both pathways renders Candida harmless to macrophages and mice, offering new avenues for treating fungal infections.
A new international study has found a significant association between high levels of trans fatty acids and breast cancer in European women. The research suggests that reducing trans fatty acid consumption through dietary changes may help protect against breast cancer development.
A nationwide effort to find genes that determine susceptibility to rheumatoid arthritis has been launched, with researchers collecting medical information and genetic material from 1,000 families. The project aims to identify genetic regions shared by affected siblings, which may contain genes involved in the disease.
Scientists found that heart damage in Chagas' disease patients is due to the immune system's reaction to parasitic infections, contrary to previous thought. The study has significant implications for treatment and prevention strategies.
Researchers at Purdue University have developed an oral delivery method for insulin that may eventually treat human diabetes. The method uses a gel-like material to protect insulin from stomach enzymes, allowing it to release the drug in a location where it can work.
A prospective study conducted by researchers at the University at Buffalo found that surgery for endometriosis dramatically improves pain and discomfort in most women. The study also showed that women who had previously given birth were twice as likely to get pregnant again following surgery, while advancing age reduced fertility.
