    • New Caltech Scholars Urged to Take Advantage of Research Opportunities
      Incoming students and postdoctoral scholars gathered with friends, family, and Caltech faculty and administrators at the 17th annual convocation ceremonyTogether on campus for the first time, Caltech's newest community members—undergraduate and graduate students and postdoctoral scholars—were formally welcomed to the Institute by Vice President for Student Affairs Joseph E. Shepherd and President Thomas F. Rosenbaum […]
    • What is in People's Minds When They Buy Stocks?
      When people buy stocks, they tend to have beliefs in place about how well the investments will perform and which ones are riskier bets. Economists would love to know what is going on in people's minds, but because that is not always possible, they instead come up with models to predict how people will behave. […]
    • New Polymer Heart Valve Implanted in First Patient
      Device devised by Caltech's Mory Gharib lasts longer with fewer complications than current  optionsCaltech researchers have helped to design a new generation of heart valves that are longer-lasting, cost less to manufacture, and are more biocompatible than options that are currently available to patients. As part of an FDA trial, one of the new valves […]
    • Caltech to Celebrate National Postdoc Appreciation Week September 16–20
      To celebrate the work of its postdoctoral scholars, Caltech will mark National Postdoc Appreciation Week from September 16–20 with events including workshops on public speaking and Title IX issues, a hike, and a picnic.Caltech Postdoc Association (CPA) chair Carolyn Ladd, a postdoctoral scholar in chemistry, says the week of events aims to recognize Caltech postdocs […]
    • Beyond the Limits of Nature: A Conversation with Kaihang Wang
      Bioengineer Kaihang Wang is pushing life's limits. As a recent addition to Caltech's faculty, the assistant professor studies how to create artificial life forms in his laboratory by designing and building genomes—the DNA blueprints for organisms—from scratch. We sat down with Wang to discuss synthetic biology and his goal of creating new forms of life.What […]
    • First Overtones "Heard" in the Ringing of a Black Hole
      When two black holes collide, they merge into one bigger black hole and ring like a struck bell, sending out ripples in space and time called gravitational waves. Embedded in these gravitational waves are specific frequencies, or tones, which are akin to individual notes in a musical chord.Now, researchers have detected two such tones for […]
    • New Metamaterial Morphs Into New Shapes, Taking on New Properties
      A newly developed type of architected metamaterial has the ability to change shape in a tunable fashion.While most reconfigurable materials can toggle between two distinct states, the way a switch toggles on or off, the new material's shape can be finely tuned, adjusting its physical properties as desired. The material, which has potential applications in […]
    • A Metal Unlike Itself
      One of the most fundamental rules physics students learn in college is that metals cannot possess an internal electric field. This makes metals, in a sense, opposite to "ferroelectrics," which are materials that spontaneously create their own electric fields. However, for nearly 50 years, scientists have wondered if perhaps a metal could act unlike itself […]
    • Caltech Faculty Honored with Breakthrough and New Horizons Prizes
      Caltech's Katherine L. (Katie) Bouman has been named a recipient of the 2020 Breakthrough Prize for Fundamental Physics as part of the Event Horizon Telescope (EHT) team that generated the first-ever image of a black hole, while Xie Chen and Xinwen Zhu have each received 2020 New Horizons prizes from the same foundation for their […]
    • Planetary Collisions Can Drop the Internal Pressures in Planets
      Researchers present a new paradigm for understanding how pressures in planets evolveA new study from Caltech shows that giant impacts can dramatically lower the internal pressure of planets, a finding that could significantly change the current model of planetary formation.The impacts, such as the one that is thought to have caused the formation of the […]
