    DNA data offer evidence of unknown extinct human relative

    VANCOUVER — Traces of long-lost human cousins may be hiding in modern people’s DNA, a new computer analysis suggests.

    People from Melanesia, a region in the South Pacific encompassing Papua New Guinea and surrounding islands, may carry genetic evidence of a previously unknown extinct hominid species, Ryan Bohlender reported October 20 at the annual meeting of the American Society of...

    Virus triggers immune proteins to aid enemy

    View the video

    Crucial immune system proteins that make it harder for viruses to replicate might also help the attackers avoid detection, three new studies suggest. When faced with certain viruses, the proteins can set off a cascade of cell-to-cell messages that destroy antibody-producing immune cells. With those virus-fighting cells depleted, it’s easier for the invader to persist...

    First peek under clouds reveals Jupiter’s surprising depths

    PASADENA, Calif. — Jupiter’s clouds have deep roots. The multicolored bands that wrap around the planet reach hundreds of kilometers down into the atmosphere, NASA’s Juno spacecraft reveals, providing an unprecedented peek into the giant planet’s interior.

    “Whatever’s making those colors and stripes still exists pretty far down,” planetary scientist Scott Bolton, head of the Juno mission...

    Blame bad incentives for bad science

    Most of us spend our careers trying to meet — and hopefully exceed — expectations. Scientists do too. But the requirements for success in a job in academic science don’t always line up with the best scientific methods. The net result? Bad science doesn’t just happen — it gets selected for.

    What does it mean to be successful in science? A scientist gets a job and funding by publishing a...

    Maps show genetic diversity in mammals, amphibians around the world

    View the slideshow

    Maps have long been used to show the animal kingdom’s range, regional mix, populations at risk and more. Now a new set of maps reveals the global distribution of genetic diversity.

    “Without genetic diversity, species can’t evolve into new species,” says Andreia Miraldo, a population geneticist at the Natural History Museum of Denmark in Copenhagen. “It...

    Warmer waters bring earlier plankton blooms

    Spring brings blooms, and not just on land. Warmer waters spur growth of a tiny ocean-dwelling bacteria. More than 10 years of data collected at an unusually high-tech ocean observatory reveal that the speedy growth of the phytoplankton Synechococcus is driven by an uptick in temperature. As spring’s warmth comes earlier, so does the phytoplankton’s annual growth spurt, resulting in a shift in...

    There’s a new way to stop an earthquake: put a volcano in its path

    A titanic volcano stopped a mega-sized earthquake in its tracks.

    In April, pent-up stress along the Futagawa-Hinagu Fault Zone in Japan began to unleash a magnitude 7.1 earthquake. The rupture traveled about 30 kilometers along the fault until it reached Mount Aso, one of Earth’s largest active volcanoes. That’s where the quake met its demise, geophysicist Aiming Lin of Kyoto University...

    Ancient armored fish revises early history of jaws

    A freaky fish with a head like a dolphin and a body like a tank may be to thank for human jaws.

    The discovery of a 423-million-year-old armored fish from China suggests that the jaws of all modern land vertebrates and bony fish originated in a bizarre group of animals called placoderms, researchers report in the Oct. 21 Science.

    Along with a different placoderm fossil from 2013,...

    Staph infections still a concern

    New hope for control of staph infections

    Staphylococcal infections — especially rampant in hospitals and responsible for … some fatal disorders — may be virtually stamped out. Researchers … have extracted teichoic acid from the bacteria’s cell wall and used it to protect groups of mice from subsequent massive doses of virulent staph organisms. — Science News, October 29, 1966

    Mars lander silent as mission scientists work out what went wrong

    The Schiaparelli Mars lander remains silent since its attempted landing October 19 on the Red Planet. All data transmitted by the lander during its descent have been relayed to Earth, and mission scientists are now in the thick of trying to figure out what went wrong.

    “I am extremely confident that we'll be able to fully understand what happened,” ESA spacecraft operations manager Andrea...
