Composite subatomic structures created by powerful collisions of protons have fallen apart in unexpected ways within a detector in the Large Hadron Collider called LHCb.
Marvin L. "Murph" Goldberger, an emeritus professor of physics who was dean of UC San Diego’s Division of Natural Sciences from 1994 to 1999, following a prominent career that included working on the Manhattan Project and serving as the president of Caltech, died Nov. 26 in La Jolla. He was 92.
Stars igniting at rates rarely seen in a distant, massive galaxy are blowing cold, dense gas tens of thousands of light years into space, depleting the galaxy's supply of stellar fuel. The loss will limit future star birth, a driver galactic aging for which evidence has been mounting.
A hinge in the RNA genome of the virus that causes hepatitis C works like a switch that can be flipped to prevent it from replicating in infected cells. Scientists have discovered that this shape is shared by several other viruses—among them one that kills cancer cells.
A self-driven reaction can assemble phospholipid membranes like those that enclose cells, a team of chemists at the University of California, San Diego, reports in Angewandte Chemie.
Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical signaling changes as a food reward drives learning, they report in Nature Methods online October 26.
Physicists have come up have with a mathematical explanation for moths’ remarkable ability to find mates in the dark hundreds of meters away.
Cosmologists have made the most sensitive and precise measurements yet of the polarization of the cosmic microwave background.
Physics majors at the University of California, San Diego will have the opportunity to gain experience and training on the same high-tech tools that industry researchers use, thanks to contributions from Quantum Design. The San Diego-based technology company—which has strong alumni ties to the campus—is…
