    Weizmann Physics Discovery is a 2014 Breakthrough of the Year

    The magazine Physics World has announced that research by Weizmann Institute scientists that revealed a fundamental principle of particle physics is one of its ""10 highly commended breakthroughs"" of 2014. The work, by Dr. Roee Ozeri and colleagues, involves isolating the magnetic interactions of electrons – something scientists have been attempting for decades.

    Divine Secrets of the Ant Sisterhood

    Ants are altruistic and cooperative, but how do they communicate and assign roles? A Weizmann team is using tools from information theory, statistical and theoretical physics, computer science, systems biology, neuroscience, and biology to investigate.

    Super Supernovae

    Weizmann astrophysicist Dr. Avishay Gal-Yam writes in Scientific American about his hunt for supernovae, which resulted in, among other discoveries, finding a type of explosion more powerful than previously thought possible.

    Shedding Light on Dark Matter: Israeli, European and Arab Scientists Team Up

    It is theorized that dark matter comprises most of the universe – however, it has never been detected. Why not? As Weizmann's Dr. Ran Budnik tells <em>Haaretz</em>, ""about 100,000 dark matter particles pass through an area the size of a thumbnail each second."" But existing instruments aren't sensitive enough to identify the tiny particles. Enter XENON1T.

    When the Earth Shakes

    Using special techniques and materials, Dr. Einat Aharonov compresses long-term geophysical events, such as how the Earth is moved and how it is formed, so that they can be studied in her lab.

    Will Quantum Physics Revolutionize the Digital World?

    Under quantum theory, particles can be in different places, in different states, doing different things – at the same time. And computers based on these principles might complete, reasonably quickly, calculations that would take today's computers a million years. Weizmann scientists are leading the quest to develop the next generation of computers.

    XENON1T Dark Matter Experiment Launched

    What is dark matter, the unseen stuff that makes up most of our universe? No one knows – yet. Thanks to the new XENON1T experiment, just inaugurated at the Gran Sasso lab in Italy, an international team of scientists will be able to search for dark matter with unprecedented sensitivity. Dr. Ran Budnik heads the Weizmann Institute's pivotal XENON1T team.

  • How the Mighty Winds of Uranus and Neptune Blow

    Giant planets are dominated by winds that can reach supersonic speeds; however, just how deep those winds reached was unknown … until now. reports on how the Weizmann Institute's Dr. Yohai Kaspi and team resolved what ""has been an open question for the last 25 years.""

    Earth-Mass Planet Right Next Door

    A potentially habitable planet – Proxima Centauri b – has been found virtually next door to Earth: about four light years away. Dr. Aviv Ofir, who is in Prof. Oded Aharonson's lab, is a member of the "Pale Red Dot" project; the team found that the new planet likely has balmy temperatures and liquid water, albeit a fast orbit. Further research is underway.

    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.
