The lowering of the ocean's pH is making it harder for corals to grow their skeletons and easier for bioeroding organisms to tear them down. Erosion rates increase tenfold in areas where corals are also exposed to high levels of nutrients, according to a new study. As sea level rises, these reefs may have a harder time growing toward the ocean surface, where they get sunlight they need to survive.

Noninvasive brain scans have led to basic science discoveries about the human brain, but they've had only limited impacts on people's day-to-day lives. A review article highlights a number of recent studies showing that brain imaging can help predict an individual's future learning, criminality, health-related behaviors, and response to drug or behavioral treatments. The technology may offer opportunities to personalize educational and clinical practices.

Following cancer prevention guidelines from the American Cancer Society may modestly reduce your overall risk of developing cancer and have a greater impact on reducing your overall risk of dying early, a study of nearly a half-million Americans has found. Having a healthy body weight and staying active appeared to have the most positive impact.

Since the discovery of how DNA encodes genetic information, most research on the evolution of life has focused on genes. According to the 'selfish gene' theory, cells and organisms exist simply as packages to protect and transmit genes. New research challenges this idea, proposing instead that if anything is 'selfish' it must be the ribosome. That upends everything we think we know about the evolution of life and, in fact, the function of ribosomes themselves.

Our sense of belonging to the male or female gender is an inherent component of the human identity perception. As a general rule, gender identity and physical sex coincide. If this is not the case, one refers to trans-identity or transsexuality. In a current study, brain researchers were able to demonstrate that the very personal gender identity of every human being is reflected and verifiable in the cross-links between brain regions.
