Two-Day ‘Hackathon for Startups’ Hopes to Spark Student Innovations

May 2, 2016

The new “Startup UCSD,” described as a two-day hackathon for startups, encourages the creative, innovative, and problem-solving students at UC San Diego to bring their ideas to a venue where workshops, professional advisors, and campus resources can help bring those ideas to fruition.

Weak Brain Circadian Rhythms Cause Depression-Like Behavior in Mice

May 2, 2016

When the master pacemaker that normally synchronizes circadian rhythms in the brain is disrupted, that disruption causes helplessness, behavioral despair, and anxiety-like behavior in mice, say scientists at the University of California San Diego.

Three Earth-Sized Planets Found Orbiting a Tiny Nearby Star

May 2, 2016

An international team of astronomers composed of UC San Diego astrophysicists has discovered three Earth-sized planets orbiting near the “habitable zone” of an ultracool dwarf star, the first planets ever discovered around such a tiny and dim star.

‘Adaptive Protein Crystal’ Could Form New Kind of Protective Material

May 2, 2016

Chemists at UC San Diego have created an “adaptive protein crystal” with a counterintuitive and potentially useful property: When stretched in one direction, the material thickens in the perpendicular direction, rather than thinning as familiar materials do. And when squeezed in one dimension, it shrinks in the other rather than expanding, and gets denser in the process.

How DNA Can Take on the Properties of Sand or Toothpaste

May 2, 2016

When does DNA behave like sand or toothpaste? When the genetic material is so densely packed within a virus, it can behave like grains of sand or toothpaste in a tube. That’s essentially what biophysicists at UC San Diego discovered when they began closely examining the physical properties of DNA jammed inside viruses.

SDSC Supercomputers, CIPRES Gateway Help Define New “Tree of Life”

April 25, 2016

An outline for a new tree of life, depicting the evolution of life on this planet that included more than 1,000 new types of bacteria and Archaea lurking in the Earth’s nooks and crannies, was made possible with the help of supercomputing resources and a phylogenetics “gateway” created at the San Diego Supercomputer Center (SDSC), based at the University of California San Diego.

Neuronal Structures Associated with Learning and Memory Sprout In Response to Novel Molecules

April 11, 2016

Chemists at the University of California San Diego have designed a set of molecules that promote microscopic, anatomical changes in neurons associated with the formation and retention of memories. These drug candidates also prevent deterioration of the same neuronal structures in the presence of amyloid-beta, a protein fragment that accumulates in the brains of people with Alzheimer's disease.

Breathing is a Rhythm for Life, and More

April 1, 2016

Respiration is more than just an essential rhythm for life. A new study has found that rhythmic neural patterns that control breathing also coordinate movements of muscles on the mouth and face that serve a variety of sensory, ingestive and social behaviors.

Two UC San Diego Professors Named Fellows to Prestigious Math Society

April 1, 2016

Two professors at UC San Diego have been named 2016 Fellows of the Society of Industrial and Applied Mathematics “for their distinguished contributions to the disciplines of applied mathematics, computational science and related fields.”

Electric Grid Monitoring Laboratory Opens at UC San Diego

March 24, 2016

Engineers from academia and industry will harness the power of control theory to help improve the way electric power grids are operated in San Diego and beyond in a new research laboratory that opened this month on the University of California, San Diego campus.
