  • Mechanistic basis of oxygen sensitivity in...
    on October 30, 2020 at 1:30 pm

    Titanium is extremely sensitive to small amounts of oxygen, which can lead to markedly decreased ductility of the material. Materials scientists therefore aim to lower the costs of purifying titanium, while avoiding the poisoning effects of oxygen. In a new report now on Science Advances, Yan Chong, and a team of scientists in materials science and engineering at the University of California Berkeley and the Lawrence Berkeley National Laboratory in the U.S., detailed a systematic study on […]

    The LIGO Scientific Collaboration and Virgo Collaboration released a catalog of results from the first half of its third observing run (O3a), and scientists have detected more than three times as many gravitational waves than the first two runs combined. Gravitational waves were first detected in 2015 and are ripples in time and space produced by merging black holes and/or neutron stars. Several researchers from Rochester Institute of Technology's Center for Computational Relativity and […]

    A team of scientists including two physicists at the University of Sussex has found a way to circumvent a 178-year old theory which means they can effectively cancel magnetic fields at a distance. They are the first to be able to do so in a way which has practical benefits.

    Bots and conspiracy theorists have infested the Twitter chatter around the upcoming U.S. presidential election, USC researchers have found.

  • Topology gets magnetic: The new wave of...
    on October 28, 2020 at 4:00 pm

    The electronic structure of nonmagnetic crystals can be classified by complete theories of band topology, reminiscent of a "topological periodic table." However, such a classification for magnetic materials has so far been elusive, and hence very few magnetic topological materials have been discovered to date. In a new study published in the journal Nature, an international team of researchers has performed the first high-throughput search for magnetic topological materials, finding over 100 […]
