Why sex with a partner is better

A study by University of Oregon researchers found that nematode worms with partners were more resistant to genetic mutations and better adapted to changing environments. This suggests that having a mate provides an evolutionary advantage over self-fertilization, leading to longer lives for offspring.

'Killer' Southeast drought low on scale, says study

A new study finds that a 2005-2007 drought in the southeastern United States was not exceptional but rather part of a normal dry period, while population growth and poor planning are major contributors to water scarcity. The region's future droughts are uncertain and could strike at any time due to unpredictable weather patterns.

Native Americans descended from a single ancestral group, DNA study confirms

A DNA study confirms that Native Americans and Greenlanders share a common ancestral population, with the '9-repeat allele' present in all Native American populations and absent in other Asian groups. This evidence supports the single ancestral population theory, ruling out multiple mutations and natural selection hypotheses.

Model of pre-exposure prophylaxis against HIV forecasts benefits, potential cost-effectiveness

A new mathematical model predicts that pre-exposure prophylaxis (PrEP) could substantially reduce the lifetime risk of HIV infection, but its cost-effectiveness varies depending on target population and drug costs. With modest improvements, PrEP might be as effective as other public health interventions.
