  • Reck-Peterson Named HHMI Investigator

    What drives your curiosity?

    Deciphering basic mechanisms in cell biology has led to many advances in medicine and agriculture. My curiosity to understand the mechanisms of intracellular transport is what drives me.” – Samara Reck-Peterson, new UC San Diego HHMI Investigator

  • Biology Undergraduates Honored for Research Achievements

    Two UC San Diego Biological Sciences undergraduates have been recognized for their outstanding research achievements.

    Sarah Medina and Jiayan Tan were selected to receive Dr. Milton H. Saier Sr. Memorial Awards for outstanding original research achievements in the biology of single-celled organisms known as prokaryotes.

  • Researchers Identify Gene That Helps Prevent Brain Disease

    Protein ‘proofreading’ errors lead to neurodegenerative disease

    Scientists know that faulty proteins can cause harmful deposits or “aggregates” in neurological disorders such as Alzheimer’s and Parkinson’s disease. Although the causes of these protein deposits remain a mystery, it is known that abnormal aggregates can result when cells fail to transmit proper genetic information to proteins. University of California San Diego Professor Susan Ackerman and her colleagues first highlighted this cause of brain disease more than 10 years ago. Now, probing deeper into this research, she and colleagues have identified a gene, Ankrd16, that prevents the protein aggregates they originally observed.

  • Scientists Find Missing Factor in Gene Activation

    Answer to decades-long mystery could play a part in cancer and other human diseases

    Until human genes are activated, they are blocked by structures known as nucleosomes, components that serve to package DNA inside cells.

  • Two Biology Graduate Students Receive National Science Foundation Fellowships

    Danielle Garshott and Homa Rahnamoun, graduate students in UC San Diego’s Division of Biological Sciences, have been awarded prestigious 2018 National Science Foundation (NSF) Graduate Research Fellowships.

  • A Drug Lord and the World’s Largest Invasive Animal

    At his infamous zenith in the 1990s, Pablo Escobar’s drug-fueled empire—a vast underworld syndicate built upon the United States’ insatiable appetite for cocaine—made him one of the wealthiest criminals in history.

  • Three UC San Diego Professors Elected to the American Academy of Arts and Sciences

    The American Academy of Arts and Sciences, one of the country’s most esteemed honorary societies and independent policy research centers, has elected three professors of the University of California San Diego as new members.

  • Jim Posakony Honored with 2018 UC San Diego Integrity Award

    Respect. Honesty. Fairness. Trust.

    Such qualities were highlighted across campus during UC San Diego’s 8th Annual Integrity Awards ceremony.

  • Researchers Uncover Mechanisms That Impair Immune System Defenses

    Core processes suppressing anti-viral immunity could be relevant in cancer attacks

    The human immune system maintains intricate defenses against a constant wave of attacks from pathogens, but such protections are not limitless. Eventually, these defenses lose their effectiveness or simply stop working against attacks from viruses, bacteria, parasites and even tumors.

  • Brain Activity Linked to Stress Changes Chemical Codes

    Findings may be relevant to other disorders, from autism to PTSD

    Five years ago, a team of University of California San Diego neurobiologists published surprising findings describing how rats’ brain cells adopted new chemical codes when subjected to significant changes in natural light exposure—much as humans suffer from “winter blues,” the type of depression known as seasonal affective disorder. A new study implicates a role for light-induced electrical activity in controlling chemical codes.

  • Researchers Develop First Gene Drive Targeting Worldwide Crop Pest

    Innovation establishes method to control invasive fly that deposits eggs in fruit crops, causing millions in damage

    Biologists at the University of California San Diego have developed a method of manipulating the genes of 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.
