UC San Diego biologists have created the world’s first gene drive system—a mechanism for manipulating genetic inheritance—in Drosophila suzukii, an agricultural pest that has invaded much of the United States and caused millions of dollars in damage to high-value berry and other fruit crops.

Biologists have discovered evidence for a new path of evolution, and with it a deeper understanding of how quickly organisms such as viruses can adapt to their environment. Publishing in the journal Science, the researchers say their findings, which address longstanding mysteries of how genes acquire new functions and how mutations arise to ease transmission from one host to another, could be applied to investigations of viral diseases such as Zika, Ebola and bird flu.

The inaugural chair holder of the Junior Seau Foundation Endowed Chair in Traumatic Brain Injury at the University of California San Diego is Yishi Jin, Professor and Chair of the Section of Neurobiology in the Division of Biological Sciences. Jin’s research focuses on molecular genetic mechanisms underlying the development of the nervous system, and regeneration of wounded nervous systems, with the goal of better understanding human neurological disorders and brain injury.

Working at the intersection of biology and physics, scientists at UC San Diego have made a surprising discovery at the root of cell formation. They found that DNA executes an unexpected architectural role in shaping the cells of bacteria. Studying the bacterium Bacillus subtilis, the researchers used an array of experiments and technologies to reveal that DNA, beyond serving to encode genetic information, also “pumps up” bacterial cells.

Employing CRISPR/Cas9 advancements, UC San Diego researchers are using new active genetics technology to reveal new fundamental mechanisms that control gene activity. The authors also provide experimental validation for using active genetics as an efficient means for targeted gene insertion, or “transgenesis,” and single-step replacement of genetic control elements.

Using new technologies developed to extract life history information from bones, researchers at UC San Diego are learning more than ever about populations of green sea turtles living in the eastern region of the Pacific Ocean. While their numbers remain dangerously depleted, the new data show that green sea turtles are spending more time offshore, increasing their risk as fishing bycatch.

Researchers on the hunt for genes involved in regenerating critical nerve fibers came away with a surprise: The discovery of a new genetic pathway that carries hope for victims of traumatic injuries—from stroke to spinal cord damage. Although no cures exist for many nervous system injuries, if the damaged neurons do not die, “there is hope to find ways to make them stronger and help them regrow,” said senior author Yishi Jin.

An unprecedented UC San Diego study integrating data from around the globe has shown that honey bees are the world’s most important single species of pollinator in natural ecosystems and a key contributor to natural ecosystem functions. The report weaves together information from 80 plant-pollinator interaction networks.

The combined effects of pesticides and a lack of nutrition form a deadly one-two punch for animals, new research shows for the first time. Researchers studied how honey bees fared with exposure to pesticides and limited nutrient sources, scenarios found in agricultural areas. They were surprised to find that bee deaths increased by up to 50 percent more than they expected.
