    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...

    Tropical songbirds get their growth spurt late

    Scientists have long puzzled over why tropical songbirds lay fewer eggs than their temperate-zone counterparts. A new study suggests that it may have to do with how baby birds grow.

    Thomas Martin of the University of Montana in Missoula compared nestling development in 72 songbird species from Arizona, Venezuela and Malaysia. While the Arizona birds grew quickly in the early days after...

    Decoy switches frogs’ mating call preference

    A trick that salesmen use to sell expensive cars may help average frogs snag mates.    

    Female túngara frogs often switch which of two mating calls they prefer upon hearing a third, unattractive mating call, researchers report in the Aug. 28 Science. This action resembles a human behavior known as the “...

    Mountains, craters revealed in latest images of dwarf planet Ceres

    Mountains, plains and craters take center stage in a new batch of images from the Dawn spacecraft, which has been in orbit around the dwarf planet Ceres since March 6. A 6-kilometer-high mountain and rippling terrain are just two of the...
