    Students Join Safe-Cracking Competition

    The Safe-Cracking Club at the Weber School in Sandy Springs (near Atlanta) was one of dozens of teams from all over the world to travel to the Weizmann campus and challenge other teams to break into their safes. But they were the only team to place first among Americans. The annual safecracking tournament challenges high schoolers to use physics to construct a secure safe.

  • Yizhar, Oren_lab
    Lighting Up the Mechanisms of Brain Disease

    In Issue No. 47 of Weizmann Views, serendipity leads Dr. Ofer Yizhar to his life’s work: pioneering the remarkable new field of optogenetics. Optogenetics combines optics – the branch of physics concerned with light – and genetics to offer previously unimaginable new ways of studying the brain. Dr. Yizhar's work has particular import for the understanding of autism.

    Explosive Material: The Making of a Supernova

    Weizmann scientists lead the team that observed - and measured - the earliest supernova explosion ever, an estimated three hours after it began. Tight coordination between multiple observatories and institutions enabled these unprecedented measurements, which were then analyzed by a global team.

    AJA Safecrackers Going to Israel

    As the Atlanta Jewish Times reports, students from the Atlanta Jewish Academy are taking part in the Weizmann Institute’s International Safe-Cracking Tournament for the second consecutive year. In the tournament, teams from all over the world use the principles of physics to build a safe, and try to break into each other's constructions.

    A Black Hole? Where?

    Guy Nir, a doctoral student at the Weizmann Institute, writes in The Jerusalem Post about black holes - e.g., what they are, how they are studied, and the like. This easy-to-read explanation sheds light on some of today’s greatest astrophysics discoveries.

    The Spectacular Aftermath of a Supernova Was Just Seen at Its Earliest Stage Ever

    The Washington Post reports on the remarkable recent observation of a supernova within just 3 to 10 hours of its explosion. A global network of astrophysicists - from California to Israel to Hawaii - collaborated in real time to take measurements of the supernova, the youngest ever witnessed. Weizmann’s Dr. Ofer Yaron was the lead scientist on the paper.

  • A Multiple-Impact Origin for the Moon

    While the predominant theory for the Moon’s existence was a single, massive impact with Earth, our satellite’s origins were still mysterious. Now, complex computer simulations by Prof. Oded Aharonson show that the more likely explanation is multiple impacts of varying sizes that produced many moonlets; over time, these joined to form the Moon we know today.

  • Burdick-TheManyMoonsTheory-800
    The Many-Moons Theory

    The New Yorker's Alan Burdick reports on the recent findings from Prof. Oded Aharonson's lab, which revealed that our moon was likely formed by multiple collisions, rather than the single-impact theory that prevails today.

  • Star Being Shredded Produces Unusual Super-Flash

    On June 14, 2015, astrophysicists around the world noted an extraordinarily bright flash of light that, puzzlingly, did not fit any of the usual explanations. Prof. Avishay Gal-Yam’s lab has now solved the mystery: it was the destruction of a star by the gravitational tides of a black hole at the center of its galaxy. This event is extremely rare, as a number of physics conditions must be satisfied.
