The study's findings suggest HIV positive men may be more suitable candidates for fertility treatments due to lower infection rates.
Duke University researchers found that exercise reduces potentially harmful cholesterol levels in the blood. The extent of this benefit depends on exercise amount and intensity, as well as gender. After a five-year trial, they discovered that high-intensity exercise led to sustained benefits in HDL cholesterol for both men and women.
Philip Morris advertised in gay media to 'own the market,' but quickly distanced itself from the community. The company ultimately settled a boycott by agreeing to financially support HIV/AIDS groups.
A new study examines how much of the nation's population lives within a certain distance of each county's center, revealing that areas in the South and West are making inroads. The leading edge of top-tier accessibility has inched southward from the Midwest and Northeast to include significant portions of North Carolina and Tennessee.
The study found that many HIV-infected gay and bisexual men tailor their sexual activity to reduce the risk of HIV transmission to casual partners they do not disclose to. Barriers to disclosure include stigma and fears of rejection, suggesting that public health efforts must address these concerns.
Researchers are conducting clinical trials at a new MIT facility dedicated to neutron capture therapy (NCT), which has shown promise in reducing damage to healthy tissues. The treatment involves administering a compound containing boron-10, followed by irradiation with epithermal neutrons, killing tumor cells while sparing healthy ones.

Researchers at Johns Hopkins University have identified a protease in the SARS virus genome, which could be a target for new drugs. The team is now working to characterize the protease's structure and properties to validate its value as a drug development target.
A study of over 570 children found that those who were breastfed had better math, spelling, and reading skills compared to bottle-fed children whose mothers smoked during pregnancy. The researchers suggest that long-chain polyunsaturated fatty acids in breast milk may promote brain development and counteract the negative effects of smo...
A study by Cornell University researchers found that listeriosis cases are more likely to occur in clusters, which can help identify the source of contamination. This new understanding has the potential to prevent outbreaks and save lives.
Researchers have developed the most effective commercially available black coating, NPL Super Black, with a low reflectance of 0.35% in the visible region. This breakthrough has significant implications for fields like radiometry, spectroscopy, and optical metrology, where stray light reduction is crucial.
A study found that regular indoor swimming pool attendance is associated with increased lung damage and a higher risk of childhood asthma. The researchers measured lung proteins in children who swam regularly at indoor pools, finding significant associations with cellular damage and respiratory issues.
Researchers found that nitrogenous bases could protect primordial RNA from UV radiation, leading to a selective advantage and increased stability. This mechanism may have driven the origin of life on Earth, turning high UV levels into a key factor in the process.
Research at Duke University Medical Center shows that physical inactivity leads to a significant increase in visceral fat, while high amounts of exercise can lead to significant decreases. The study also found that lower amounts of exercise prevented the accumulation of visceral fat but did not lead to improvements.
A nationwide study found that husbands and wives have significant differences in their reports of family finances, with men typically overestimating the couple's income and women overestimating the family's debts. These discrepancies may impact relationships and national economic statistics, according to Jay Zagorsky, author of the study.
