Ancient Biological Clockwork Revealed Using ‘Secret Sauce’

A new paper released in the prestigious journal Science explains how the labs of LiWang and his colleagues — Professor Carrie Partch in the Department of Chemistry and Biochemistry at UC Santa Cruz and Professor Susan Golden in the Division of Biological Sciences at UC San Diego — captured assemblies of the proteins that direct cyanobacterial circadian rhythms, or biological clocks, in large complexes and made spectroscopic “snapshots” of their different formations using X-ray crystallography and nuclear magnetic resonance (NMR) spectroscopy.

Sergey Kryazhimskiy Named 2017 Sloan Research Fellow

Sergey Kryazhimskiy, an assistant professor of biology, in the Division’s Section of Ecology, Behavior and Evolution is one of six-early career faculty members at UC San Diego who have won prestigious 2017 Sloan Research Fellowships for achievements that mark them as the nation’s future leaders in science and technology.

In Memoriam: Jonathan Singer 1924-2017

Jonathan Singer, one of the first members of the biology faculty at UC San Diego who helped build the campus into a world leader in molecular and cell biology, died on February 2 in La Jolla, CA. He was 92.

UC San Diego Biologists Unlock Code Regulating Most Human Genes

Molecular biologists at UC San Diego have unlocked the code that initiates transcription and regulates the activity of more than half of all human genes, an achievement that should provide scientists with a better understanding of how human genes are turned on and off.

Study Shows Signs of Hope for Endangered Sea Turtles

Bones from dead turtles washed up on Mexican beaches indicate that Baja California is critical to the survival of endangered North Pacific loggerhead sea turtles, which travel some 7,500 miles from their nesting sites in Japan to their feeding grounds off the coast of Mexico.

Biologists Discover How Viruses Hijack Cell’s Machinery

Biologists at UC San Diego have documented for the first time how very large viruses reprogram the cellular machinery of bacteria during infection to more closely resemble an animal or human cell—a process that allows these alien invaders to trick cells into producing hundreds of new viruses, which eventually explode from and kill the cells they infect.

Bacteria Recruit Other Species with Long-Range Electrical Signals

Biologists at UC San Diego who recently found that bacteria resolve social conflicts within their communities and communicate with one another like neurons in the brain have discovered another human-like trait in these apparently not-so-simple, single-celled creatures.

Candice Sy Wins First Gabriele Wienhausen Biological Sciences Scholarship

The Division of Biological Sciences celebrated Candice Sy as the inaugural winner of the Gabriele Wienhausen Biological Sciences Scholarship at a special event on Nov. 15, 2016. Named in honor of Gabriele Wienhausen, Ph.D., who served as Associate Dean of the Division for nearly eight years, the endowed award recognizes students who share her passion and dedication to the Division and UC San Diego.

Junior Seau Foundation Supports Brain Injury Studies and Education at UC San Diego

Matching funds will bring total support to $1 million for critical research and community outreach efforts

The Junior Seau Foundation has pledged $250,000 to support brain injury research and education at the University of California San Diego. The gift is made in memory of the beloved NFL Football Hall of Famer and longtime San Diego Charger, Junior Seau, who passed away in 2012 and was subsequently diagnosed with chronic traumatic encephalopathy (CTE), a neurodegenerative disease associated with repeated blows to the head. The funds will be used to establish the Junior Seau Endowed Faculty Fellowship in Traumatic Brain Injury (TBI), as well as the Junior Seau Lectureship Series to inform the community and K-12 students about the causes and risks associated with traumatic brain injury.

Biologists Watch Speciation in a Laboratory Flask

Biologists have discovered that the evolution of a new species can occur rapidly enough for them to observe the process in a simple laboratory flask.

In a month-long experiment using a virus harmless to humans, biologists working at the University of California San Diego and at Michigan State University documented the evolution of a virus into two incipient species—a process known as speciation that Charles Darwin proposed to explain the branching in the tree of life, where one species splits into two distinct species during evolution.
