Male homosexuality doesn’t make complete sense from an evolutionary point of view. One possible explanation is what evolutionary psychologists call the “kin selection hypothesis.” What that means is that homosexuality may convey an indirect benefit by enhancing the survival prospects of close relatives.

New evidence that genetics play a significant role in some premature births may help explain why a woman can do everything right and still give birth too soon. Researchers have identified DNA variants in mothers and fetuses that appear to increase the risk for preterm labor and delivery.

Scientists in Texas are reporting that a technique used in the search for new drugs could also be used in the quest to discover new, environmentally friendly materials for fighting global warming. Such materials could be used to capture the greenhouse gas carbon dioxide from industrial smokestacks and other fixed sources before it enters the [...]

Children who were exposed to acetaminophen prenatally were more likely to have asthma symptoms at age five in a study of 300 African-American and Dominican Republic children living in New York City. This is the first study to demonstrate a direct link between asthma and an ability to detoxify foreign substances in the body.
Scientists in Poland are describing how a medical imaging technique has taken on a second life in revealing forgery of an artist’s signature and changes in inscriptions on paintings that are hundreds of years old.

Researchers have found that three different degenerative brain disorders are linked by a toxic form of the same protein. Elk-1 was found in clumps of misshaped proteins that are the hallmarks of Parkinson’s disease, Alzheimer’s disease, and Huntington’s disease. This suggests a molecular link between the presence of inclusions and neuronal loss that is shared [...]
