  • How scientists detected gravitational waves for the first time

    How scientists detected gravitational waves for the first time

    Scientists have announced the first detection of gravitational waves, a finding that will give astronomers an entirely new window to the universe. But how are these waves observed and why have we never seen them before? Gravitational waves are ripples in the space-time continuum first predicted...

    With a deft snip, potential treatment emerges for deadly childhood Duchenne Muscular Dystrophy

    Using cells from patients with Duchenne Muscular Dystrophy, a genetic disease that affects one in 5,000 boys, UCLA scientists have devised a strategy for creating "corrected" stem cells that could restore tissue under attack by the deadly muscle-wasting disorder. A gene-editing procedure described...

    Why scientists are so excited over first detection of gravitational waves

    Since humans first gazed at the heavens, they have observed the universe primarily through the window of the electromagnetic spectrum, including visible light waves, radio waves, and X-rays. But it turns out that using light in its various forms is not the only way to peer into space. Now, with...

    Plastic microbead pollution harms oysters, the ocean's critical ecosystem engineers, study finds

    Oysters eat by filtering the water around them and digesting anything small enough to trap, whether that’s algae, phytoplankton — or tiny pieces of plastic floating in the ocean. It stands to reason that the plastic isn't good for them. Now scientists know why: It takes such a toll on their digestive...
