    Why kids may be at risk from vinyl floors and fire-resistant couches

    WASHINGTON — Home decor like furniture and flooring may not be notorious polluters like gas-guzzlers, but these indoor consumer products can also be significant sources of potentially dangerous chemicals.

    Kids who live in homes with all vinyl flooring or living room couches that contain flame retardants have much higher concentrations of chemicals called semivolatile organic compounds in...

    Climate change could increase foodborne illness by energizing flies

    Warmer springs and summers could make house flies friskier, spreading diarrhea-causing bacteria to more places. As a result, foodborne Campylobacter infections could increase with climate change, proposes epidemiologist Melanie Cousins of the University of Waterloo in Canada. 

    Cousins’ computer simulation, still a proof-of-concept version, focuses on how the warm weather surge in house...

    A rare, ancient case of bone cancer has been found in a turtle ancestor

    A 240-million-year-old case of bone cancer has turned up in a fossil of an extinct ancestor of turtles. Dating to the Triassic Period, the fossil is the oldest known example of this cancer in an amniote, a group that includes mammals, birds and reptiles, researchers report online February 7 in JAMA Oncology. 

    The fossilized left femur from the shell-less stem-turtle Pappochelys rosinae...

    In some cases, getting dengue may protect against Zika

    Previous infections with dengue virus may have protected some people in an urban slum in Brazil from getting Zika.

    In a study of more than 1,400 people in the Pau da Lima area of Salvador, those with higher levels of antibodies against a particular dengue virus protein were at lower risk of contracting Zika, researchers report in the Feb. 8 Science. “The higher the antibody, the higher...

    Pills equipped with tiny needles can inject a body from the inside

    For those of us who cringe at the sight of needles, there may someday be a less daunting alternative to getting a shot: swallowing a pill-sized device that delivers medication by painlessly pricking the inside of the stomach.

    A prototype of the device, described in the Feb. 8 Science, administers insulin. But similar ingestible capsules could also replace skin injections of antibodies...

    Why some children may get strep throat more often than others

    For kids, getting strep throat again and again is a pain. It’s also a problem little understood by scientists. Now a study that analyzed kids’ tonsils hints at why such repeat infections may happen.

    Children with recurrent strep infections had smaller immune structures crucial to the development of antibodies in their tonsils than kids who hadn’t had repeated infections, researchers...

    Gut connection

    Abnormal proteins tied to Parkinson’s disease may form in the gut before traveling through the body’s nervous system to the brain, Laura Beil reported in “A gut-brain link for Parkinson’s gets a closer look” (SN: 12/8/18, p. 22).

    The vagus nerve offers a connection between nerves in the gut and those in the brain. Beil reported on one study that showed that people who...

    Lack of sleep is tied to increases in two Alzheimer's proteins

    A sleep-deprived brain is awash in excess amounts of not one but two proteins whose bad behavior is implicated in Alzheimer’s disease.

    A new study finds excessive amounts of a protein called tau in the fluid that bathes the brain and spinal cord of extremely sleep-deprived adults. Tau, which is tied to nerve cell death, tangles and spreads throughout the brain during Alzheimer’s. An...
