Physicists Explain Puzzling Particle Collisions

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.

Prominent UC San Diego Physicist and Dean Dies at 92

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.

Triton Rocket Club in Furious Race to Make Campus First University to Launch Rocket into Space

It’s Wednesday afternoon, and about a dozen students are hard at work trying to make history in the basement of Jacobs Hall. The students are building a 20-foot, two-stage rocket that they hope will make UC San Diego the first higher education institution to successfully send a rocket into space.

Galactic Blowout

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.

Viral Switches Share a Shape

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.

Cell membranes self-assemble

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.
