“A Major Conceptual Advance” on El Niño

The east-west shift of a warm blob of water in the equatorial Pacific Ocean has been the main characteristic of El Niño, but 2023 flipped the script, says a team of researchers led by Scripps Institution of Oceanography at UC San Diego.

Survey Shows Educational Impact of Antarctic Citizen Science Program Among Travelers

In a new study evaluating the impact of the FjordPhyto citizen science program, survey data showed that travelers visiting Antarctica expressed an appreciation for learning about ecosystems and climate change while feeling enriched by citizen science engagement.

Use of Metformin Associated with Exceptional Longevity Among Older Women

In a study of older adult women with diabetes, metformin, a widely used diabetes medication, was associated with a 30% lower risk of death before age 90 compared to use of sulfonylurea, another diabetes medication.

The Long Pathway to Cell Organization and Growth

Sterols are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic pathways. Researchers from UC San Diego have used a novel approach to show how they interact with other lipids that help cells self-organize.

Min Proteins for Max Efficiency During Cell Division

The Min protein system prevents abnormal cell division in bacteria, but is poorly understood. Researchers from UC San Diego have uncovered how engineered e.coli bacteria control protein levels for maximum efficiency.

High Cannabis Use Linked to Increased Mortality in Colon Cancer Patients

Researchers at the University of California San Diego School of Medicine have found that individuals with colon cancer and a documented history of high cannabis use were more than 20 times more likely to die within five years of diagnosis compared to those without such a history.

Using “Shallow Shadows” to Uncover Quantum Properties

Traditional methods of looking into quantum systems often require immense resources. Research from UC San Diego have developed a new approach that allows scientists to extract essential information more efficiently and accurately.

Human and HPV Genes Combine to Form Extrachromosomal DNA That Promotes Oropharyngeal Tumor Growth

HPV-associated oropharyngeal cancers are becoming more common. A new study finds that human and HPV DNA hybridize in cancer cells, creating extrachromosomal DNA which drives the growth of tumors.

Gene Identified That Blocks Healing after Spinal Cord Injury

With no approved therapies for spinal cord injuries, scientists are looking into the body’s healing mechanisms for clues on recovery. Researchers found that a gene named RYK inhibits wound healing, offering hope for new treatments for paralysis after spinal cord injury.

Advanced Imaging Reveals Mechanisms That Cause Autoimmune Disease

Those who suffer myasthenia gravis experience muscle weakness that can affect the muscles we use to blink, smile and move our bodies. Researchers at UC San Diego’s School of Biological Sciences used a cutting-edge imaging technique to uncover new details about the mechanisms underlying the disease.
