Long assumed to be destructive to tissues and cells, “free radicals” generated by the cell’s mitochondria—the energy producing structures in the cell—are actually beneficial to healing wounds. That’s the conclusion of biologists at UC San Diego who discovered that “reactive oxygen species”—chemically…
The evolution of worms, insects, vertebrates and other “bilateral” animals—those with distinct left and right sides—from less complex creatures like jellyfish and sea anemones with “radial” symmetry may have been facilitated by the emergence of a completely new "operating system" for controlling…
Four teams of scientists at UC San Diego will receive research grants from the National Institutes of Health that will help lay the groundwork for visualizing the circuits of the brain and how they work, the agency announced at a White House ceremony today.
Researchers at University of California, San Diego School of Medicine have identified a control mechanism for an area of the brain that processes sensory and emotive information that humans experience as “disappointment.”
Four scientists at UC San Diego are among 36 recipients nationwide who have been awarded early concept grants for brain research from the National Science Foundation, the agency announced today.
Researchers at the University of California, San Diego School of Medicine have evidence suggesting that neurons in the developing brains of mice are guided by a simple but elegant birth order rule that allows them to find and form their proper connections.
A study of juvenile rat brain cells suggests that the effects of a commonly used anesthetic drug on the connections between brain cells are temporary.
David Victor, UC San Diego School of International Relations and Pacific Studies professor and director of the Laboratory on International Law and Regulation, gave his first testimony to the U.S. Nuclear Regulatory Commission (NRC) Tuesday, July 15 as part of his role to help keep the public informed…
Let’s say you’re a bee and you’ve spotted a new and particularly lucrative source of nectar and pollen. What’s the best way to communicate the location of this prize cache of food to the rest of your nestmates without revealing it to competitors, or “eavesdropping” spies, outside of the colony?
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
