    Pluto may have spots the size of Missouri

    A chain of enigmatic dark spots mark the surface of Pluto in recent New Horizons images, taken when the spacecraft was about 22 million kilometers from the dwarf planet. Each splotch is about 500 kilometers across and covers roughly the same area as the state of Missouri.

    The...

    Genetic tweak hints at why mammoths loved the cold

    A single genetic change may have made woolly mammoths fat, hairy and cold-loving.

    Researchers deciphered the genomes of two woolly mammoths that died about 20,000 and 60,000 years ago. When comparing the mammoths’ DNA to that from three Asian elephants, researchers noted that mammoths had different forms of some proteins involved in sensing temperature.

    The team produced one of the...

    Smell test may detect autism

    A 10-minute test could help doctors sniff out autism, a new study contends.

    Whether smelling roses or sour milk, children with autism inhale about the same amount of air, researchers report July 2 in Current Biology. In contrast, kids without the disorder breathe in pleasant scents more deeply than stinky ones.

    The...

    Science is heroic, with a tragic (statistical) flaw

    First of two parts

    Science is heroic. It fuels the economy, it feeds the world, it fights disease. Sure, it enables some unsavory stuff as well — knowledge confers power for bad as well as good — but on the whole, science deserves credit for providing the foundation underlying modern civilization’s comforts and conveniences.

    But for all its heroic accomplishments, science...

    Centipede discovered in caves 1,000 meters belowground

    A newly discovered centipede species takes extreme living to new depths.

    Scientists discovered Geophilus hadesi more than 1,000 meters underground in damp, nearly freezing caves in central Croatia. The centipede is just under 3 centimeters long and has 33 pairs of legs, plus unusually long antennae. Researchers...

    Your photos reveal more than where you went on vacation

    Summer is upon us and that means clichéd vacation photos are nigh. But that picture of your cousin holding up the leaning tower of Pisa or of Fred from accounting jumping in front of [insert national monument here] could be a data point in a bigger picture. Scientists are tapping into the vast repositories of photo sharing...

    Flatworm can self-fertilize by stabbing itself in the head

    Lonely hermaphroditic flatworms with needle-tipped male organs apparently inject themselves with sperm in whatever body region is easy to stab.

    If raised alone in the lab, a tiny Macrostomum hystrix flatworm ends up with sperm distributed oddly around its body, researchers report July 1 in ...

    Heat turns wild genetic male reptiles into functional females

    Some genetically male Australian bearded dragons are growing up as fully functional females in the wild — the first reptiles confirmed to reverse sex under natural conditions.

    Eleven of 131 Pogona vitticeps lizards caught at several sites in southeastern Australia during three years had female sex organs but the male ZZ set of sex chromosomes, says Clare Holleley of the...

    E-cigarette reports provide science that society craves

    For much of the last year, the most-read story on sciencenews.org was not about a faraway exoplanet or a cunning creature’s adaptations to an exotic locale. It was a short report, in some ways unsurprising. In 26 different weeks since it appeared in June 2014,...
