  • Brain activity that underlies risky choices

    When rats were trained to choose between high- and low-risk options while a circuit in their brains was monitored and manipulated, a specific signal in that circuit determined their choice.


  • Accelerating protein evolution

    A new tool enables researchers to test millions of mutated proteins in a matter of hours or days. The technology could speed the search for new medicines, industrial enzymes and biosensors.


  • A word with Karl Deisseroth

    Karl Deisseroth, MD, PhD, calls the human brain “the most complicated object in the universe.” The Stanford psychiatrist and bioengineer is well-known for developing two game-changing techniques — optogenetics and CLARITY.


  • Deisseroth wins $3 million prize

    Initiated in 2013 by Silicon Valley entrepreneurs, the annual award — the world’s largest in dollar terms — honors pioneers in life sciences, fundamental physics and mathematics.
