    This stick-on patch could keep tabs on stroke patients at home

    AUSTIN, Texas — Stretchy sensors that stick to the throat could track the long-term recovery of stroke survivors.

    These new Band-Aid‒shaped devices contain motion sensors that detect muscle movement and vocal cord vibrations. That sensor data could help doctors diagnose and monitor the effectiveness of certain treatments for post-stroke conditions like difficulty swallowing or talking,...

    Americans would welcome alien life rather than fear it

    AUSTIN, Texas — If alien microbes crash-land on Earth, they may get a warm welcome.

    When people were asked how they would react to the discovery of extraterrestrial microbial life, they give generally positive responses, researchers reported at a news conference February 16 at the annual meeting of the American Association for the Advancement of Science.

    This suggests that if...

    Ants practice combat triage and nurse their injured

    No wounded left behind — not quite. Ants that have evolved battlefield medevac carry only the moderately wounded home to the nest. There, those lucky injured fighters get fast and effective wound care.

    Insect colonies seething with workers may seem unlikely to stage elaborate rescues of individual fighters. Yet for Matabele ants (Megaponera analis) in sub-Saharan Africa — with a mere 1,...

    James Webb Space Telescope challenges artists to see in infrared

    With an astronomer’s toolkit and an artist’s eye, Zoltan Levay has transformed raw data from the Hubble Space Telescope into stunning space vistas for almost a quarter century (SN: 4/18/15, p. 4). He’s now preparing for a new challenge: Working with light not visible to human eyes.

    Levay’s next charge is the James Webb Space Telescope, set to launch in 2019. Unlike Hubble, which mostly...

    To hear the beat, your brain may think about moving to it

    If you’ve ever felt the urge to tap along to music, this research may strike a chord.

    Recognizing rhythms doesn’t involve just parts of the brain that process sound — it also relies on a brain region involved with movement, researchers report online January 18 in the Journal of Cognitive Neuroscience. When an area of the brain that plans movement was disabled temporarily, people...

    Strong winds send migrating seal pups on lengthier trips

    PORTLAND, Ore. — Native American fishermen in Alaska have long said that seal pups go with the wind rather than struggle against it. Now, a new study confirms that wisdom. Migrating northern fur seal pups travel hundreds of kilometers farther in blustery years than in milder years, researchers reported February 14 at the American Geophysical Union’s Ocean Sciences meeting. Those epic journeys...

    Household products make surprisingly large contributions to air pollution

    AUSTIN, Texas — To reduce your impact on air quality, you might expect to trade in your gas-guzzling clunker of a car — but you can also unplug those air fresheners. 

    In urban areas, emissions from consumer goods such as paint, cleaning supplies and personal care products now contribute as much to ozone and fine particulate matter in the atmosphere as do emissions from burning gasoline...

    Fossil footprints may put lizards on two feet 110 million years ago

    Fossilized footprints from an iguana-like reptile provide what could be the earliest evidence of a lizard running on two legs.

    The 29 exceptionally well-preserved lizard tracks, found in a slab of rock from an abandoned quarry in Hadong County, South Korea, include back feet with curved digits and front feet with a slightly longer third digit. The back footprints outnumber the front ones...

    In Borneo, hunting emerges as a key threat to endangered orangutans

    Orangutan numbers on the Southeast Asian island of Borneo plummeted from 1999 to 2015, more as a result of human hunting than habitat loss, an international research team finds.

    Over those 16 years, Borneo’s orangutan population declined by about 148,500 individuals. A majority of those losses occurred in the intact or selectively logged forests where most orangutans live,...

    Look to penguins to track Antarctic changes

    PORTLAND, Ore. — Penguins preserve records of Antarctic environmental change. The birds’ feathers and eggshells contain the chemical fingerprints of variations in diet, food web structure and even climate, researchers reported February 12 at the American Geophysical Union’s 2018 Ocean Sciences Meeting.

    The Antarctic environment has changed dramatically in recent decades. Overfishing has...
