Clues in coral bleaching mystery Posted: 05 Sep 2013 10:40 AM PDT Coral reefs are tremendously important for ocean biodiversity. Unfortunately they have been in great decline in recent years, much of it due to the effects of global climate change. One such effect, called bleaching, occurs when the symbiotic algae that are essential for providing nutrients to the coral either lose their identifying photosynthetic pigmentation and their ability to perform photosynthesis or disappear entirely from the coral's tissue. Without a healthy population of these algae, the coral cannot survive.

What is the brain telling us about the diagnoses of schizophrenia? Posted: 05 Sep 2013 05:56 AM PDT We live in the most exciting and unsettling period in the history of psychiatry since Freud started talking about sex in public. On the one hand, the American Psychiatric Association has introduced the fifth iteration of the psychiatric diagnostic manual, DSM-V, representing the current best effort of the brightest clinical minds in psychiatry to categorize the enormously complex pattern of human emotional, cognitive, and behavioral problems. On the other hand, in new and profound ways, neuroscience and genetics research in psychiatry are yielding insights that challenge the traditional diagnostic schema that have long been at the core of the field.
