    Ultrasmall engines bend second law of thermodynamics

    Car engines and batteries run because of the second law of thermodynamics, which appears to work, with just a little bending, for ultrasmall engines in the quantum realm as well.

    Physics

    Gravity waves from black holes verify Einstein’s prediction

    Gravitational waves, tremors in the cosmic fabric of space and time predicted by Einstein a century ago, have finally been detected, opening a new avenue for exploring the universe.

  3. tetraneutrons
    Particle Physics

    Physicists find signs of four-neutron nucleus

    Strong evidence of a tetraneutron, an atomic nucleus with four neutrons but no protons, defies physicists’ theoretical expectations.

    Quantum Physics

    Quantum histories get all tangled up

    Multiple versions of history may be quantum entangled just like particles, a new experiment suggests.

  5. Advanced LIGO in Livingston, Louisiana
    Astronomy

    As first run of gravitational wave search winds down, rumors abound

    Advanced LIGO has completed its first search for gravitational waves. Researchers are crunching the data as rumors swirl of a detection.

  6. hummingbird simulation
    Animals

    Capturing the wonders of hummingbird flight

    Recent computer simulations reveal how hummingbirds manipulate the air around them to aid in flight.

  7. Astronomy

    Clues left at a galactic hit-and-run

    Scientists may have discovered a dwarf galaxy that triggered a “galaxy quake” when it buzzed by the Milky Way a few hundred million years ago.

  8. red giant
    Astronomy

    Red giants map how the Milky Way grew

    A new catalog of the ages of our galaxy’s stars confirms that the Milky Way grew from the inside out.

  9. star explosion simulation
    Astronomy

    Newfound gas cloud may be graveyard of first stars

    A 12-billion-year-old gas cloud, rich in hydrogen and helium but nothing else, may house the remains of the universe’s first stars.

  10. black hole
    Physics

    At last, some details on Stephen Hawking’s solution to black hole problem

    Stephen Hawking and colleagues have finally provided more information about how black holes might preserve information.

  11. black hole
    Physics

    More details on Stephen Hawking’s solution to black hole problem

    Stephen Hawking and colleagues have finally provided more information about how black holes might preserve information.

  12. hydrogen squeezing experiment
    Chemistry

    Experiment offers glimpse at how to make hydrogen metallic

    A new phase of hydrogen could represent the stepping stone for transforming element 1 into a metal.
