    Nearby quasar may be home to dynamic duo

    The closest quasar to Earth might harbor a rare pair of supermassive black holes. The dark duo is probably left over from a galaxy collision, researchers report, and offers a way to test theories about gravity and the growth of galaxies.

    Black hole couples should pop up in the center of pretty much every galaxy at some point, as galaxies grow by colliding with one another. This galactic...

    New microscope techniques give deepest view yet of living cells

    Two new microscopy techniques are helping scientists see smaller structures in living cells than ever glimpsed before.

    Scientists can now view structures just 45 to 84 nanometers wide, Nobel prize-winning physicist Eric Betzig of the Howard Hughes Medical Research...

    How dollhouse crime scenes schooled 1940s cops

    In November 1896, Lizzie Miller stumbled upon a shocking sight: The discolored body of her neighbor Maggie Wilson half-submerged in a bathtub, legs precariously dangling over the side. How did she die and who killed her?

    Wilson’s murder is fiction, though inspired by the work of...

    Life after Pluto: New Horizons to head for Kuiper belt boulder

    With Pluto receding in the rear view mirror, New Horizons now has its sights set on a second target. Pending final approval by NASA, an icy boulder dubbed 2014 MU69 — over 1 billion kilometers beyond Pluto — will be graced by the spacecraft’s presence on January 1, 2019, space agency officials...

    Volcanic activity convicted in Permian extinction

    The biggest catastrophe in the history of life on Earth resulted from one of the most titanic volcanic outpourings on record, new research concludes.

    At the close of the Permian period around 252 million years ago, more than 90 percent of all marine species and roughly 75 percent of all land species vanished. New high-precision analysis of ancient lavas determines this extinction...

    Coral competitor becomes ally in fight against starfish

    Coral and algae don’t get along. On reefs, algae compete with coral, reducing coral growth and survival. Scientists suspect that the algae may also promote harmful bacteria or coral-eating species, causing further coral damage.

    But coral have an even bigger worry: the crown-of-thorns starfish. These are large (up to about a third...

    New experiment verifies quantum spookiness

    It’s official: Quantum mechanics is spooky.

    A new experiment provides the best evidence yet that the common-sense concept of locality — that an event on Earth can’t immediately influence what happens on Mars, for instance — doesn’t apply in the quantum realm.

    Researchers have long thought that quantum theory is nonlocal. But airtight...

    The need to feed and eating for pleasure are inextricably linked

    You’ve already had a muffin. And a half. You know you’re full. But there they are, fluffy and delicious, waiting for the passersby in the office. Just thinking about them makes your mouth water.

    Maybe if you just slice one into quarters. I mean, that barely counts…

    And then we give in, our brains overriding our body’s better judgment. When I catch myself once again polishing off a...

    Vaccinated man excretes live poliovirus for nearly 3 decades

    A British man has been excreting live poliovirus for an estimated 28 years.

    An immune deficiency allowed weakened virus from oral polio vaccines to replicate and change within the man’s body. This case is not unique, but it’s the longest-lasting example of vaccine-derived poliovirus on record, researchers report August 27 in...

    Psychology results evaporate upon further review

    Psychologists have recently bemoaned a trend for provocative and sometimes highly publicized findings that vanish in repeat experiments. A large, collaborative project has now put an unsettling, and contested, number on the extent of that problem.

    Only 35 of 97 reports of statistically significant results published in three major psychology journals in 2008...
