  1. Physics

    Gravity waves detected at last!

    Albert Einstein predicted gravitational waves 100 years ago. Now scientists have detected them coming from the collision of two black holes.

  2. Physics

    Explainer: What are gravitational waves?

    Albert Einstein had predicted that large catastrophes, like colliding black holes, should produce tiny ripples in the fabric of space. In 2016, scientists reported finally detecting them

  3. Animals

    Why some penguin feathers never freeze

    Oil and tiny pores prevent the feathers on some penguins from freezing. The discovery could inspire new ways to keep ice off of airplane wings.

  4. Space

    New recipe for monster black holes

    The conventional idea for how black holes form would not easily allow for huge ones to develop in the early universe. Yet they did. Now a scientist offers a new view: galaxy mash-ups!

  5. Chemistry

    News Brief: 2016 brings four new elements

    U.S., Russian and Japanese scientists have just been credited with official discoveries of elements 113, 115, 117 and 118. Next up: Naming them.

  6. Physics

    Zombie stars: A source of gravitational waves?

    Scientists have found indirect evidence that the dense cores of dead stars are making ripples in space, known as gravitational waves. These waves have been predicted but never yet directly “seen.”

  7. Physics

    Particles that zip through matter snare Nobel

    Two scientists won the 2015 Nobel Prize in physics for their discovery that neutrinos, particles that can pass through almost all matter, have mass.

  8. Physics

    Stephen Hawking says his group has solved a black hole puzzle

    Physicist Stephen Hawking says light sliding along the outside of a black hole holds the key to understanding what’s inside.

  9. Materials Science

    Long-sought subatomic particle ‘seen’ at last

    Physicists have finally caught a brief glimpse of massless subatomic particles that were first predicted to exist 85 years ago. It’s the elusive Weyl fermion.

  10. Physics

    Bacteria help water effortlessly go with the flow

    By adding bacteria to water, scientists were able to make a fluid flow with almost no resistance.
