    • Caltech Mourns the Passing of Murray Gell-Mann (1929–2019)
      Murray Gell-Mann, Caltech's Robert Andrews Millikan Professor of Theoretical Physics, Emeritus, and a winner of the 1969 Nobel Prize in Physics, passed away on May 24, 2019. He was 89 years old.Gell-Mann helped bring order to the field of particle physics in the 1950s and 1960s—a time when a bewildering array of new particles was […]
    • Comet Inspires Chemistry for Making Breathable Oxygen on Mars
      Science fiction stories are chock full of terraforming schemes and oxygen generators for a very good reason—we humans need molecular oxygen (O2) to breathe, and space is essentially devoid of it. Even on other planets with thick atmospheres, O2 is hard to come by.So, when we explore space, we need to bring our own oxygen […]
    • "Neural Lander" Uses AI to Land Drones Smoothly
      Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often the […]
    • Shaw Prize in Astronomy Awarded to Ed Stone
      Edward (Ed) C. Stone, the David Morrisroe Professor of Physics at Caltech, and the project scientist for NASA's Voyager mission for the past 47 years, has been awarded the prestigious Shaw Prize in Astronomy "for his leadership in the Voyager project, which has, over the past four decades, transformed our understanding of the four giant […]
    • Caltech Undergrad Weighs in on Privacy Laws
      In 2018, then-California Governor Jerry Brown signed the California Consumer Privacy Act (CCPA), enhancing consumer privacy rights and protections. The CCPA stiffens penalties for companies if personal data that they hold are disclosed or stolen, prompting debate about how privacy should be regulated, and what level of government—state or federal—should be responsible for doing so.Caltech […]
    • Watson Lecture Preview: Linda Hsieh-Wilson
      Sugars, also called glycans, are one of the four major classes of macromolecules that make up living systems (along with proteins, nucleic acids, and lipids). Glycans assemble into complex structures on the surfaces of cells, forming a thick, fuzzy coating that surrounds cells and modulates the ability of cells to communicate (with other cells). In […]
    • Shayna Chabner Named Caltech's Chief Communications Officer
      Shayna Chabner, an experienced communications professional who has spent nearly a decade at Caltech, has been appointed the Institute's Chief Communications Officer. She will assume her new position on June 3.Chabner, who most recently served as the Senior Director of Strategy and Special Projects in the Office of Strategic Communications, will now lead Caltech's strategic communications […]
    • Anxious People Quicker to Flee Danger
      Fear and anxiety are both responses to danger but differ in timing. Fear strikes when something is an imminent threat: a tiger jumps over a fence, lunging at you. Anxiety, on the other hand, occurs when you have a moment to consider a threat: you spot a tiger in the distance and have time to […]
    • Dangerous Pathogens Use This Sophisticated Machinery to Infect Hosts
      Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance […]
    • Artist-in-Residence to Screen Experimental Film on Campus
      In the experimental film series Peggy and Fred in Hell, a pair of children wander through an apocalyptic world, the cultural remains of a lost society. They are like feral children raised by television and the sole survivors of an unspecified catastrophe. The surrealistic project, which includes 17 episodes filmed and produced over three decades, […]
