A genetic mutation in the CCR5 gene provides protection against HIV infection, slowing the spread of AIDS in African populations. Studies suggest that this mutation may be more common in European populations due to historical epidemics.
The Tropical Rainfall Measuring Mission (TRMM) spacecraft will continue to provide vital data on global rainfall and climate change with its extended mission. Scientists anticipate improved climate predictions and a more robust record of rainfall patterns.
Experts analyze a study finding that religious involvement has the largest impact on early adolescent self-esteem. They caution against overlooking practical implications and highlight limitations of the study's explanations.
Researchers have discovered that a T arrangement in molecular electronic switches enables efficient communication between distant molecules, facilitating the on and off states of the switch. This finding broadens design possibilities for molecular photonics, solar energy conversion, and nanotechnology.
Researchers from UNC School of Medicine and Pharmacy have developed a new method to calculate protein stability, which could improve drug design and engineering. The approach uses computational manipulations to predict the effects of amino acid mutations on protein stability.
A national survey of eighth graders found that religious involvement has the largest influence on their self-esteem, with positive effects observed in African American girls and White male students. The study suggests that churches and families play a significant role in shaping young adolescents' self-evaluations.
The American College of Physicians-American Society of Internal Medicine has released a comprehensive guide for primary care doctors on obesity diagnosis and management. Obesity rates increased by 30% between 1980 and 1994, carrying significant direct health care costs for the United States. The guide addresses key aspects of medical a...
Research reveals that US nature reserves are unevenly distributed across ecological zones, leaving many plant and animal species unprotected. The study suggests that involving the private sector in conservation strategies can help preserve America's biodiversity.
A recent UCSF study found that fine needle biopsy (FNAB) accuracy can be significantly improved with formally trained physicians. The researchers analyzed 927 women's medical histories and tissue samples, finding that less-well-trained practitioners were more likely to miss cancers due to errors in sampling.
