Biologists at UC San Diego have found that rats experience more anxiety and depression when the days grow longer. More importantly, they discovered that the rat’s brain cells adopt a new chemical code when subjected to large changes in the day and night cycle, flipping a switch to allow an entirely different neurotransmitter to stimulate the same part of the brain.
Biologists at UC San Diego have identified eight genes never before suspected to play a role in wound healing that are called into action near the areas where wounds occur.
An international team of neuroscientists has described for the first time in exhaustive detail the underlying neurobiology of an amnesiac who suffered from profound memory loss after damage to key portions of his brain.
Ocean biology alters the chemical composition of sea spray in ways that influence its ability to form clouds over the ocean. That’s the conclusion of a team of scientists using a new approach to study tiny atmospheric particles called aerosols that can influence climate by absorbing or reflecting sunlight and seeding clouds.
Can scientists rid malaria from the Third World by simply feeding algae genetically engineered with a vaccine? That’s the question biologists at UC San Diego sought to answer after they demonstrated last May that algae can be engineered to produce a vaccine that blocks malaria transmission. In a follow up study, they got their answer: Not yet, although the same method may work as a vaccine against a wide variety of viral and bacterial infections.
U.S. Secretary of the Navy Ray Mabus announced the nation's newest research vessel will be named R/V Sally Ride, in honor of the former UC San Diego faculty member who was the first American female astronaut and the youngest American to fly in space.
