    Lab creates new, unexpected type of ‘firenadoes’

    A newly discovered type of fiery vortex burns hot and generates little soot. Scientists suspect it could be a solution to cleaning up oil spills at sea.

    Scientists Say: Aufeis

    Water keeps flowing underground even in the coldest Arctic winters. But when it comes to the surface, it chills out and forms large layers of ice — called aufeis.

    Algae embedded in sea ice drive the Arctic food web

    Scientists traced where zooplankton in the Arctic get their energy from. Many open ocean species rely on algae found in sea ice, which is disappearing.

    Scientists Say: Albedo

    To measure how much light reflects off an object, scientists measure its albedo.

    Oxygen-rich air emerged super early, new data show

    Scientists had thought animals were slow to emerge because they would have needed oxygen-rich air to breathe. A new study finds that plentiful oxygen may have developed early. So animals may have been late on the scene for another reason.

    The first farmers were two groups, not one

    The humans that began farming 10,000 years ago in the Fertile Crescent may have been two cultures living side-by-side.

    Scientists Say: Hoodoo

    When softer rocks are covered with a harder rock layer, weathering can wear away the softer stone. This will leave behind tall thin towers — hoodoos.

    Something in plastics may be weakening kids’ teeth

    The body can confuse some pollutants for a natural hormone. Researchers in France now find such pollutant exposures in childhood may lead cells to make defective tooth enamel.

    Non-scents: Pollution can confuse pollinators’ sniffers

    New research uses computers to predict how much longer it takes bees and other pollinating insects to sniff out lunch in a polluted environment.

    Climate closing the gender gap for this mountain flower

    Among valerian plants, males like it hotter than the females do. So a warming climate has been speeding their migration up once-cool mountainsides.

    Falling through Earth might be a long and fruitless trip

    A classic physics problem asks what would happen if you plunged through Earth’s center. A new study contends you could never make it to the other side.

    That’s no moon: Earth’s tiny tagalong

    A newly discovered asteroid appears to be orbiting Earth, like a new mini-moon. In fact, it’s really orbiting the sun.
