In a detailed study of the neurons linking the eyes and brains of mice, biologists at UC San Diego discovered that the ability of our brains and those of other mammals to figure out and process in our brains directional movements is a result of the activation in the cortex of signals that originate from the direction-sensing cells in the retina of our eyes.
Arthur M. Wolfe, an American astrophysicist who for a decade directed the Center for Astrophysics and Space Sciences at the University of California, San Diego and achieved widespread recognition for his discoveries about star formation and the early universe, died on February 17 following a battle with cancer in La Jolla, Calif. He was 74.
Biologists at UC San Diego have discovered an effective strategy that could prevent the human immune system from rejecting the grafts derived from human embryonic stem cells, a major problem now limiting the development of human stem cell therapies. Their discovery may also provide scientists with a better understanding of how tumors evade the human immune system when they spread throughout the body.
Using quantitative models of bacterial growth, a team of UC San Diego biophysicists has discovered the bizarre way by which antibiotic resistance allows bacteria to multiply in the presence of antibiotics, a growing health problem in hospitals and nursing homes across the United States.
Six professors at the University of California, San Diego have been named 2013 Fellows of the American Association for the Advancement of Science, the nation’s largest general science organization.
Most of us think of honey bees as having a bucolic, pastoral existence—flying from flower to flower to collect the nectar they then turn into honey. But while they’re capable of defending themselves with their painful stings, honey bees live in a world filled with danger in which predators seize them from the sky and wait to ambush them on flowers. Such fear drives bees to avoid food sources closely associated with predators and, interestingly, makes colonies of bees less risk-tolerant than individual bees, according to a study published in this week’s issue of the open-access journal PLOS ONE.
Species living in rain forest fragments could be far more likely to disappear than previously assumed, according to an international team of scientists that included biologists at the University of California, San Diego.
