Stealth Genetic Switch in Mosquitoes Halts Malaria Spread

July 23, 2025

Researchers have developed a system that blocks malaria transmission in mosquitoes, which continue to be the deadliest animals on Earth. The CRISPR-based gene-editing system changes a single molecule within mosquitoes, a tiny but effective change that stops the malaria-parasite transmission process.

Don’t Feed the Animals: Researchers Warn of Risks Tied to Wildlife Interactions

July 17, 2025

A study led by a UC San Diego scientist offers new warnings on the dangers of human interactions with wildlife. The new report, which focuses on elephants, indicates that human feeding of wild animals can lead to a range of problems and even result in the deaths of humans and animals.

Largest Cohort in UC San Diego Program’s History Receives Hellman Fellowships

July 15, 2025

Over 30 years ago, the Society of Hellman Fellows Program was founded at UC Berkeley and UC San Diego. The program awarded 10 Hellman Fellowships in 1995 at UC San Diego. This spring, 26 UC San Diego junior faculty members were selected to receive the crucial funding.

Neurobiology’s Terrence Sejnowski Elected to Royal Society and American Philosophical Society

July 14, 2025

Distinguished Professor Terrence Sejnowski, a pioneer in computational neuroscience who leads groundbreaking research on AI, has been selected to join two of the most prominent societies in the world: the Royal Society and the American Philosophical Society.

Voracious Honey Bees Threaten the Food Supply of Native Pollinators

July 7, 2025

A study led by UC San Diego biologists is calling attention to the availability of food for bees in the Southwestern U.S. Non-native honey bees, the study found, extract an overwhelming majority of pollen from regional flowers, posing a significant ecological threat to native bee species.

How Do We Reach Decisions? Researchers Pioneer AI Method to Uncover Cognitive Strategies

July 2, 2025

How do humans and animals make decisions? Researchers deployed AI in innovative ways to understand this process. By using tiny artificial neural networks, the researchers’ work illuminates in detail what drives an individual’s actual choices — regardless of whether those choices are optimal or not.

Living Materials Now Easier to Build with a Larger Palette of Ingredients

June 30, 2025

Sustainable materials—powered by sunlight and living microbes—that remove pollutants from water, release oxygen into a wound or heal themselves after damage could become simpler to create thanks to new research by a team of biologists and engineers at UC San Diego.

Neurobiology’s Matthew Lovett-Barron Selected for Prestigious 2025 McKnight Scholar Award

June 25, 2025

UC San Diego Assistant Professor Matthew Lovett-Barron has been selected to receive a 2025 McKnight Scholar Award, one of the most prestigious awards for junior neuroscience faculty members.

Molecule Linked to Metabolism Found to Boost Plant Growth

June 6, 2025

Researchers have completed the first comprehensive exploration of itaconate, a natural compound involved in metabolism, in plants. The researchers found that itaconate helps plants grow, a finding that offers new possibilities for maximizing crop growth to support growing global populations.
