  • Biology Graduate Student Honored for EDI Leadership

    UC San Diego Division of Biological Sciences graduate student Chandler Puritty was honored on March 1 at a ceremony recognizing university leaders who are making a difference in improving equity, diversity and inclusion (EDI).

  • Yishi Jin Named to Junior Seau Endowed Faculty Chair in Traumatic Brain Injury

    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.

  • Susan Golden to Receive International Research Honor

    Renowned circadian rhythms scientist to be honored at ceremony in Japan

    Susan Golden, a distinguished biology professor at the University of California San Diego, has been named the winner of the 2018 Aschoff and Honma Prize for Biological Rhythm Research.

  • Taking Aim at Mosquitoes and Disease

    With trailblazing genetic technologies and a passion for a certain blood-sucking bug, a new UC San Diego biologist joins the campus' campaign against disease transmission

    Enter Omar Akbari’s insect zoo and it’s immediately clear that you’ve entered a different world. It’s not that you’ve passed through several layers of containment that keep the bugs securely locked away… nor the fact that the temperature has just escalated 20 degrees… nor that the room is kept at 60 percent humidity—just the way mosquitoes like it.

  • Surprise Finding Points to DNA’s Role in Shaping Cells

    Like air inflating a balloon, DNA plays an unexpected role in cell architecture

    As a basic unit of life, the cell is one of the most carefully studied components of all living organisms. Yet details on basic processes such as how cells are shaped have remained a mystery. Working at the intersection of biology and physics, scientists at the University of California San Diego have made an unexpected discovery at the root of cell formation.

  • Active Genetics Technology Opens New Horizons

    Research using the novel technology in fruit flies reveals unexpected features and provides new enabling tools for controlling genetic inheritance and genome engineering

    In 2015, University of California San Diego biologists Ethan Bier and Valentino Gantz developed a breakthrough technology known as “active genetics,” which results in parents transmitting a genetic trait to most of their offspring (instead of 50 percent receiving the trait under standard inheritance). Immediate targets of active genetics included gene-drive systems for immunizing mosquitoes against vector borne diseases such as malaria. Bier and Gantz also proposed using active genetics for a variety of other potential human health and agricultural benefits. 

  • Novel Technologies Reveal Key Information About Depleted East Pacific Green Sea Turtles

    New habitat data show turtles are spending more time offshore, increasing their risk as fishing bycatch

    Populations of green sea turtles living in the eastern region of the Pacific Ocean have rebounded in recent years, but their numbers remain dangerously depleted. Research by led by biologists at the University of California San Diego and NOAA’s National Marine Fisheries Service is offering previously unknown information about where these turtles live and how they use their habitats, key data that will aid future conservation efforts.

  • Discovery Offers New Genetic Pathway for Injured Nerve Regeneration

    Finding could pave road to regrowth after traumatic injuries, stroke and spinal damage

    On the hunt for genes involved in regenerating critical nerve fibers called axons, biologists at the University of California San Diego 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.

    UC San Diego Biological Sciences Assistant Project Scientist Kyung Won Kim, Professor Yishi Jin and their colleagues conducted a large-scale genetic screening in the roundworm C. elegans seeking ultimately to understand genetic influences that might limit nerve regrowth in humans. Unexpectedly, the researchers found the PIWI-interacting small RNA (piRNA) pathway—long believed to be restricted to function in the germline—plays an active role in neuron damage regeneration.

  • Biology Professors Named World’s Most Influential in Their Fields

    Three UC San Diego Division of Biological Sciences faculty members are among the world’s most influential researchers in their fields, based on their publications over the past decade.

  • Worldwide Importance of Honey Bees for Natural Habitats Captured in New Report

    Global synthesis of data reveals honey bees as world’s key pollinator of non-crop plants

    An unprecedented 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 first quantitative analysis of its kind, led by biologists at the University of California San Diego, is published Jan. 10 in Proceedings of the Royal Society B.
