Study Discovers Fundamental Unit of Cell Size in Bacteria

April 13, 2017

By applying mathematical models to a large number of experiments in which bacterial growth is inhibited, a team of physicists, biologists and bioengineers from UC San Diego developed a “general growth law” that explains the relationship between the average cell size of bacteria and how fast they grow.

Six Professors at UC San Diego Named 2017 Sloan Research Fellows

February 21, 2017

Six early-career faculty members at the University of California San Diego 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

February 8, 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.

In Memoriam: Sheldon Schultz 1933-2017

February 7, 2017

Sheldon "Shelly" Schultz, one of the founding members of the physics faculty at UC San Diego, who received world-wide acclaim for his contributions to the discovery of “metamaterials," died on January 31 at his home in La Jolla, CA. He was 84.

UC San Diego Biologists Unlock Code Regulating Most Human Genes

January 24, 2017

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

January 17, 2017

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

January 12, 2017

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

January 12, 2017

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.

Biologists Watch Speciation in a Laboratory Flask

November 28, 2016

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.
