Even when women outnumber men, gender bias persists among science undergrads

Increasing gender diversity has been a long-sought goal across many of the sciences, and interventions and programs to attract more women into fields like physics and math often happen at the undergraduate level. But is representation enough to improve gender diversity in science? In a new study, researchers say there's more to the story: They've found that even when undergraduate women outnumber...

Array of radio telescopes reveals explosion on the surface of a hot dead star

An international group of researchers observed a source of variable gamma rays identified in 2010 by the NASA satellite Fermi. They used a technique called VLBI, that combines data from several radio telescopes on Earth, to produce the sharpest images to date. Surprisingly, the source of gamma rays was a symbiotic nova, a peculiar stellar system known to astronomers as V407 Cyg. The result, with...

Study finds gay and bisexual youth more likely to abandon churchgoing as they reach adulthood

Religious beliefs have shaped societal attitudes toward sexual minorities, with many religious denominations vocally opposing expanded sexual minority rights. Because of this stigmatization, lesbian, gay and bisexual individuals are less likely to affiliate with a religious group—but research from the University of Nebraska-Lincoln and Old Dominion University suggests they are not abandoning...

Closer threats inspire a more primitive kind of fear

But up close, your animal instincts jump into action and there isn't as much reasoning. And that is probably what makes it harder to extinguish the fear of a close-up threat and more likely that you'll have some long-term stress from the...
