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.
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.
A biology professor at UC San Diego who heads a research institute that brings together scientists across the campus studying circadian rhythms, the internal “biological clock” that governs the daily activities in humans and other organisms, has been named by the Howard Hughes Medical Institute an…
Biologists at UC San Diego have found the “missing link” in the chemical system that enables animal cells to produce ribosomes—the thousands of protein “factories” contained within each cell that manufacture all of the proteins needed to build tissue and sustain life.
Videos featuring Rihanna, One Direction and Bruno Mars are, not surprisingly, among YouTube’s most viewed channels. Videos on physics? While some videos on physics have gained a cult-like following and hundreds of thousands of views, the subject that makes most people’s eyes glaze over still can’t…
An astronomer long fascinated with contacting civilizations beyond our solar system becomes involved in a government-funded project to search the heavens for extraterrestrial radio signals. When the federal government ends funding for her project, she continues the effort with private support, eventually…
Astrophysicists at UC San Diego have measured the minute gravitational distortions in polarized radiation from the early universe and discovered that these ancient microwaves can provide an important cosmological test of Einstein’s theory of general relativity.
UC San Diego neurobiologists discovered that the motor cortex of the brain plays an active role in learning new motor movements. In a series of experiments using mice, the researchers showed in detail how those movements are learned over time.
Two UC San Diego faculty members have been elected to the American Academy of Arts and Sciences, one of the nation’s most prestigious honorary societies, which includes accomplished leaders from academe, business, public affairs, the humanities and the arts.
