  1. Materials Science

    Making metamaterials ‘digital’ could simplify invisibility cloaks

    The digital world of 1s and 0s has inspired a simpler way to make complex metamaterials.

  2. Quantum Physics

    Three photons entangled, not just two

    Physicists have found a way to entangle a trio of photons, but it works only once in every quadrillion attempts.

  3. Particle Physics

    Evidence for new Higgs-related particle fades away

    A close look at data from the Large Hadron Collider finds no evidence that the Higgs boson decays into a new, unknown particle.

  4. Tech

    Robot swarm takes many shapes

    One Kilobot is not very smart. But 1,000 can follow simple instructions to assemble into multiple shapes without human intervention.

  5. Materials Science

    Magnets get flipped by light

    Controlling magnetism with lasers could lead to faster computer hard drives.

  6. Environment

    Ups and downs in the quest for clean air

    Satellite views reveal good news on U.S. air pollution trends.

  7. Cosmology

    Cosmologist’s ‘Cosmic Cocktail’ is a refreshing read

    Katherine Freese shares her insights as a scientist studying dark matter and other mysterious components of the universe.

  8. Computing

    Brain-inspired computer chip mimics 1 million neurons

    By processing data in parallel, computer chips modeled after the human brain could perform certain tasks, such as pattern recognition, faster and more energy-efficiently than traditional computers.

  9. Quantum Physics

    Quantum Cheshire Cat experiment splits particles from their properties

    When facing a fork in the road, neutrons appear to go in one direction and their spins in the other.

  10. Materials Science

    Weird materials could make faster computers

    Topological insulators could speed up how computers switch between 1s and 0s.

  11. Astronomy

    Voyager may not have entered interstellar space, after all

    Two scientists argue that Voyager 1 space probe is still in solar bubble, despite NASA’s announcements to the contrary.

  12. Cosmology

    Lab version of early universe fails to solve lithium problem

    An experiment that imitated conditions from just after the Big Bang failed to explain why observed amounts of lithium don’t match those expected from theory.
