The Reykjanes Peninsula at Iceland's southwestern edge is one of the country's most populated regions, and it is also one of the most volcanically active. In 2024, sensing technology developed at Caltech was deployed in the region to study the motion of subsurface magma and its eruption into lava on the surface.Using data from the […]

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of a variety of masses and speeds. The collisions may also produce entirely new particles not predicted by the standard model, the prevailing theory of fundamental […]

Sarah Reisman, Bren Professor of Chemistry and Norman Davidson Leadership Chair of the Division of Chemistry and Chemical Engineering at Caltech, has been elected as a fellow of the American Academy of Arts and Sciences (AAAS), one of the nation's oldest honorary societies. In addition, six Caltech alumni were elected to the AAAS in 2025, […]

This year, in an especially tight competition, 21 Caltech undergraduates and 14 current and incoming graduate students have been awarded graduate research fellowships by the National Science Foundation (NSF). These three-year fellowships fund graduate study "to help ensure the quality, vitality, and strength of the scientific and engineering workforce of the United States," according to […]

Caltech professor of medical engineering Wei Gao and his colleagues are envisioning a smart bandage of the future—a "lab on skin" that could not only help patients and caregivers monitor the status of chronic wounds but also deliver treatment and speed up the healing process for those cuts, incisions, scrapes, and burns that are slow […]

A new software algorithm developed at Caltech enables researchers to easily search for viruses in RNA sequence data, enabling scientists to detect viruses in samples and study how they impact biological functions.The number of individual viruses on Earth is nearly unfathomable: There are an estimated 10 million individual viruses for each star in the universe. […]

How do pathogens become resistant to the drugs used to treat them? On April 23, 2025, at 7:30 p.m. PDT in Caltech's Beckman Auditorium, Smruthi Karthikeyan, the Gordon and Carol Treweek Assistant Professor of Environmental Science and Engineering, and a William H. Hurt Scholar, will discuss the factors that drive antimicrobial resistance (AMR): clinical misuse […]

Eshaan Patheria, a Caltech graduate student in chemistry, is one of 30 young scientists from around the world to receive the inaugural Inflection Award, an honor celebrating early-career scientists working on solutions to address climate change. Patheria was recognized for his work in the lab of professor of chemistry Kimberly See, where he strives to […]

Caltech senior Yiyi Cai will be joining the 2025 class of Gates Cambridge Scholars at the University of Cambridge next year. Cai, who grew up in Beijing and came to the United States when she entered high school, will be pursuing an MPhil in advanced computer science.Cai's particular interest is in quantum computing, a field […]

More than 13,500 scientists who have worked on experiments at the Large Hadron Collider (LHC), based in Geneva, Switzerland, have been awarded the 2025 Breakthrough Prize in Fundamental Physics for "testing the modern theory of particle physics—the Standard Model—and other theories describing physics that might lie beyond it to high precision," according to the foundation's […]
