    Early birds could achieve liftoff

    SALT LAKE CITY — Flying dinosaurs took off from the ground — no leap from the trees required.

    Ancient birds and some nonavian dinosaurs used their wings and powerful legs to launch themselves into the air, a new analysis of 51 winged dinos suggests. Paleontologist Michael Habib of the University of Southern California in Los Angeles reported the findings October 26 at the annual meeting...

    How to make a fish face, and other photo contest winners

    View slideshow

    This forlorn-looking face of a 4-day-old zebrafish embryo represents “a whole new avenue of research” for geneticist Oscar Ruiz, who studies how faces and facial abnormalities develop at the cellular level.  

    The research is possible thanks to a new method, developed by Ruiz and colleagues at the University of Texas MD Anderson Cancer Center in Houston, for mounting...

    Mars lander debris spotted

    The Schiaparelli Mars lander, missing in action since its October 19 descent, dinged the surface of the Red Planet. A black spot framed by dark rays of debris mark the lander’s final resting place, the European Space Agency reports online October 27. Its parachute, still attached to the rear heat shield, lies about 1.4 kilometers to the south, new images from the Mars Reconnaissance Orbiter...

    Ancient hookups gave chimps a smidge of bonobo DNA

    Like lipstick on a collar, new DNA evidence is pointing to ancient affairs between bonobos and chimpanzees.

    Chimps carry a small percentage of bonobo DNA, researchers report in the Oct. 28 Science. The conclusion comes from analysis of the genetic instruction books, or genomes, of 63 wild-born chimps, two captive chimps named Clint and Donald, and 10 wild-born bonobos. The apes came from...

    Scientists need to redraw picture of cell’s biggest organelle

    Textbook drawings of the cell’s largest organelle might need to be updated based on new images. Super-resolution shots of the endoplasmic reticulum reveal tightly packed tubes where previous pictures showed plain flat sheets, scientists report in the Oct. 28 Science.

    The finding helps explain how the endoplasmic reticulum, or ER, reshapes itself in response to changing conditions, says...

    Climate change shifts how long ants hang on to coveted real estate

    Heating small patches of forest shows how climate warming might change the winner-loser dynamics as species struggle for control of prize territories. And such shifts in control could have wide-ranging effects on ecosystems.

    The species are cavity-nesting ants in eastern North America. Normally, communities of these ant species go through frequent turnovers in control of nest sites. But...

    HIV came to NYC at least a decade before virus ID’d

    A genetic study of HIV viruses from the 1970s may finally clear the name of a man long identified as the source of the AIDS epidemic in the United States. HIV came to New York City between 1969 and 1973, long before the man known as Patient Zero became infected, researchers report October 26 in Nature.

    Using techniques developed to decipher badly degraded ancient DNA from fossils,...

    ‘Time crystal’ created in lab

    It may sound like science fiction, but it’s not: Scientists have created the first time crystal, using a chain of ions. Just as a standard crystal repeats in a regular spatial pattern, a time crystal repeats in time, returning to a similar configuration at regular intervals.

    “This is a remarkable experiment,” says physicist Chetan Nayak of Microsoft Station Q at the University of...

    Training for parents may lessen some autism symptoms in kids

    Training parents to better communicate with their children with autism spectrum disorder may lead to long-lasting improvements in certain symptoms, scientists report online in the Oct. 25 Lancet.

    The results are “very encouraging,” because they show long-term benefits for a relatively low-intensity treatment — one that’s delivered by parents, says clinical psychologist Geraldine Dawson,...

    With climate change, grizzly bears may hibernate less

    Rocky Mountain hikers might need to start packing more bear spray: Climate change may reduce the time that grizzly bears spend in hibernation — leaving them more time to scare the crap out of any humans wandering in their territory.

    Scientists aren’t really concerned about bear hibernation because of unwary hikers, of course. It’s because hibernation is an important time of year for a...
