Scientists Discover “Dimmer Switch” For Mood Disorders

September 18, 2014

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 UC San Diego Faculty Win ‘Early Concept’ Grants from Obama’s BRAIN Initiative

August 18, 2014

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.

Birthday Matters for Wiring-Up the Brain’s Vision Centers

July 31, 2014

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.

Study Suggests Disruptive Effects of Anesthesia on Brain Cell Connections Are Temporary

July 28, 2014

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.

Why ‘Whispers’ Among Bees Sometimes Evolve Into ‘Shouts’

July 7, 2014

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?

Discovery Provides Insights on How Plants Respond to Elevated CO2 Levels

July 6, 2014

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.

UC San Diego Biology Professor Named Prestigious HHMI Professor

June 30, 2014

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 HHMI professor.

Biologists Find ‘Missing Link’ in the Production of Protein Factories in Cells

June 22, 2014

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.

The Brain’s Balancing Act

June 22, 2014

Researchers at the University of California, San Diego School of Medicine have discovered a fundamental mechanism by which the brain maintains its internal balance. The mechanism, described in the June 22 advanced online publication of the journal Nature, involves the brain's most basic inner wiring and the processes that control whether a neuron relays information to other neurons or suppresses the transmission of information.
