    New dolphin fossil makes a splash

    Six million years ago, a relative of modern river dolphins once frolicked along Panama's Carribbean shores, researchers report September 1 in PeerJ. Unearthed in 2011, the fossilized skull, teeth and jaw bones belong to a novel dolphin species (Isthminia panamensis). 

    Researchers originally rescued the fragile specimen from...

    Nanogenerators harvest body’s energy to power devices

    Ask not what your gadgets can do for you; ask what you can do for your gadgets.

    In the race to create bionic humans, researchers are nanometers away from turning people into device chargers. Instruments called nanogenerators can harvest energy from swinging limbs, jiggling skin and ballooning lungs. And that energy can power wearable and implantable gizmos, such as pacemakers, muscle...

    Some jellyfish sting deeper than others

    Jellyfish are best avoided, in my opinion. Though beautiful to watch in an aquarium, jellies are equipped with stingers that can be harmless — or cause pain or even kill. And it can be difficult to tell the difference without some research — which you don’t really have time for when one is heading...

    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...

    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...
