Study Shows Africanized Bees Continue to Spread in California

A study conducted by biologists at UC San Diego has found that the Africanized honey bee—an aggressive hybrid of the European honey bee—is continuing to expand its range northward since its introduction into Southern California in 1994.

The study, published in this week’s edition of the journal PLOS One, found that more than 60 percent of the foraging honey bees in San Diego County are Africanized and that Africanized bees can now be found as far north as California’s delta region.

Study Finds Black Bears in Yosemite Forage Primarily on Plants and Nuts

Black bears in Yosemite National Park that don’t seek out human foods subsist primarily on plants and nuts, according to a study conducted by biologists at UC San Diego who also found that ants and other sources of animal protein, such as mule deer, make up only a small fraction of the bears’ annual diet.

Life Sciences at UC San Diego Ranked 11th Best in World

The 2015 Academic Ranking of World Universities at Shanghai Jiao Tong University has ranked UC San Diego’s life sciences program as the 11th best in the world.

UC San Diego was ranked as the 14th best university in the world and the 12th best university nationally. The life sciences were the campus’s highest ranked program in the survey.

Study Provides Hope for Some Human Stem Cell Therapies

An international team of scientists headed by biologists at UC San Diego has discovered that an important class of stem cells known as human “induced pluripotent stem cells,” or iPSCs, which are derived from an individual’s own cells, can be differentiated into various types of functional cells with different fates of immune rejection.

Ipshita Zutshi Awarded HHMI International Student Fellowship

Ipshita Zutshi, a graduate student from India working in Stefan Leutgeb’s laboratory, has been selected by the Howard Hughes Medical Institute as one of selected 45 doctoral students from 18 countries to receive fellowships that will help them complete their graduate degrees in the life sciences. The awardees will receive $43,000 during each year of the fellowship.

Alumnus David Goeddel Funds Fellowship for Next Generation Scientists

When University of California, San Diego alumnus and biotechnology pioneer David Goeddel, ’72, pledged a gift of $400,000 to establish the David V. Goeddel Endowed Graduate Fellowship at UC San Diego, his goal was to support and foster the innovators and scientists of the future. The endowed fund, which will be matched in full by the UC San Diego Division of Biological Sciences, will annually support the research and scholarly activities of outstanding Biological Sciences graduate students.

Resolving Social Conflict Is Key to Survival of Bacterial Communities

Far from being selfish organisms whose sole purpose is to maximize their own reproduction, bacteria in large communities work for the greater good by resolving a social conflict among individuals to enhance the survival of their entire community.

It turns out that, much like human societies, bacterial communities benefit when they can balance opposing needs within the group.

Flatworms Could Replace Mammals for Some Toxicology Tests

Laboratories that test chemicals for neurological toxicity could reduce their use of laboratory mice and rats by replacing these animal models with tiny aquatic flatworms known as freshwater planarians.

Scientists Create Synthetic Membranes That Grow Like Living Cells

Chemists and biologists at UC San Diego have succeeded in designing and synthesizing an artificial cell membrane capable of sustaining continual growth, just like a living cell.

Gürol Süel Wins Scialog Award

Gürol Süel, an associate professor in the Section of Molecular Biology, has been awarded one of 13 grants given by The Gordon and Betty Moore Foundation and Research Corporation for Science Advancement to five teams of investigators as part of 2015 Scialog: Molecules Come to Life.
