  1. Physics

    Laser kicks molecules into fastest ever spin

    The powerful kick of a laser has spun molecules faster than they’ve ever been spun before: 10 trillion rotations per second, or 600 trillion RPM.

  2. Particle Physics

    Exotic particle packs a foursome of quarks

    Tetraquarks could help physicists understand the universe’s first generations of matter.

  3. Cosmology

    Galaxy’s gamma-ray glow may expose dark matter

    An excess of gamma rays at the center of the Milky Way could be a signature of dark matter.

  4. Astronomy

    Neutrinos from space rain down from all directions

    Using Earth as a filter, scientists detect thousands of neutrinos from beyond the solar system.

  5. Cosmology

    Speed of early universe’s expansion determined

    The rate known as the Hubble constant is measured with great precision for the universe of 11 billion years ago.

  6. Astronomy

    This winter warrior made the gravitational waves discovery possible

    Engineer Steffen Richter played an important role in the recent gravitational waves discovery, wintering at the Amundsen-Scott research station at the South Pole and making daily treks to keep the BICEP2 telescope running.

  7. Materials Science

    Light filter lets rays through from only one direction

    Angle-sensitive light filter could improve photography, telescopes and solar energy harvesting.

  8. Physics

    A tractor beam reels in objects with sound

    A tractor beam of focused sound waves has pulled on an object as large as a Toblerone chocolate bar.

  9. Materials Science

    World’s thinnest material stretches, bends, twists

    Graphene, the thinnest known material at one carbon atom thick, can be manipulated under the microscope using tricks from a variety of paper-cutting origami called kirigami.

  10. Physics

    Shifting grains may explain earthquake lightning

    Mysterious lightning before or during earthquakes could get its spark from underground shifting.

  11. Materials Science

    Phosphorene introduced as graphene alternative

    Sheets of ultrathin phosphorus could lead to faster semiconductor electronics.

  12. Physics

    Material’s magnetism tuned by temperature

    Layered substance may lead to more reliable hard drives in the future.
