Caltech Research News

  • Sneha Aenugu, a native of Hyderabad, India, is a detective of neural mysteries. Her path has led her to explore how humans learn, act, and make decisions in the real world. In the lab, Aenugu, a member of John O'Doherty's research group, designs experiments that set out to answer difficult questions using a familiar activity: […]
  • Microbes—tiny living things like bacteria and fungi, often made up of a single cell or a colony of cells—can be found everywhere from the tropics to the Arctic and Antarctic. They are as varied as they are numerous, and many perform functions that are vital to the health of ecosystems as well as our own […]
  • The American Chemical Society (ACS) has announced that it will honor Frances Arnold, the Linus Pauling Professor of Chemical Engineering, Bioengineering and Biochemistry and director of the Donna and Benjamin M. Rosen Bioengineering Center at Caltech, with the 2025 Priestley Medal, the society's highest honor.The ACS awards the Priestley Medal annually to a single individual […]
  • Mayday! SOS! Distress signals like these are used around the world to indicate an emergency.The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if there is a lack of important building blocks like amino acids, […]
  • Richard Andersen, the James G. Boswell Professor of Neuroscience and director and Leadership Chair of the Tianqiao and Chrissy Chen Brain-Machine Interface Center at Caltech, has been awarded the 2024 International Prize for Translational Neuroscience of the Gertrud Reemtsma Foundation. The Gertrud Reemtsma Foundation supports and recognizes outstanding achievements in basic neurological research. Andersen shares […]
  • In the Richard N. Merkin Center for Pure and Applied Mathematics high in Caltech Hall, the American Institute of Mathematics (AIM) gathers mathematicians to solve confounding puzzles, often using only chalk. AIM carried that analog approach outside to celebrate its 30th birthday with a free public math party on the lawn beside Caltech Hall on […]
  • Anima Anandkumar, Bren Professor of Computing and Mathematical Sciences, and Steven H. Low, the Frank J. Gilloon Professor of Computing and Mathematical Sciences and Electrical Engineering, have been selected to receive 2025 IEEE Technical Field Awards. Anandkumar will be honored with the 2025 IEEE Kiyo Tomiyasu Award for outstanding early- to mid-career contributions to technologies […]
  • The final components of the Caltech Submillimeter Observatory (CSO), including its foundation, silver geodesic dome, and on-site buildings, have been removed from a valley atop Maunakea in Hawai‘i, and the land at the site has been restored. This officially concludes the physical decommissioning of CSO, a process that was initiated in 2015 and began in […]
  • A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single supermassive black hole. The new computer simulation upends ideas about such disks that […]
  • For hundreds of years, the clarity and magnification of microscopes were ultimately limited by the physical properties of their optical lenses. Microscope makers pushed those boundaries by making increasingly complicated and expensive stacks of lens elements. Still, scientists had to decide between high resolution and a small field of view on the one hand or […]
