    In cadaver caves, baby beetles grow better with parental goo

    Growing up inside a dead mouse could really stink, but not for some burying beetles. Their parents’ gut microbes keep the cadaver fresh, creating a nursery where the larvae can thrive.

    What burying beetle parents can do with a small dead animal is remarkable, says coauthor Shantanu Shukla of the Max Planck Institute for Chemical Ecology in Jena, Germany.  “It looks different. It smells...

    Add beer to the list of foods threatened by climate change

    Beer lovers could be left with a sour taste, thanks to the latest in a series of studies mapping the effects of climate change on crops.

    Malted barley — a key ingredient in beer including IPAs, stouts and pilsners — is particularly sensitive to warmer temperatures and drought, both of which are likely to increase due to climate change. As a result, average global barley crop yields could...

    How nectar bats fly nowhere

    Flying forward is hard enough, but flying nowhere, just hovering, is so much harder. Most bats and birds can manage the feat for only a few frantic seconds.

    Hovering means losing a useful aerodynamic shortcut, says aerospace engineer and biologist David Lentink of Stanford University. As a bat or bird flies forward, its body movement sends air flowing around the wings and providing some...

    We’re probably undervaluing healthy lakes and rivers

    For sale: Pristine lake. Price negotiable.

    Most U.S. government attempts to quantify the costs and benefits of protecting the country’s bodies of water are likely undervaluing healthy lakes and rivers, researchers argue in a new study. That’s because some clean water benefits get left out of the analyses, sometimes because these benefits are difficult to pin numbers on. As a result, the...

    Genealogy databases could reveal the identity of most Americans

    Protecting the anonymity of publicly available genetic data, including DNA donated to research projects, may be impossible.

    About 60 percent of people of European descent who search genetic genealogy databases will find a match with a relative who is a third cousin or closer, a new study finds. The result suggests that with a database of about 3 million people, police or anyone else with...

    The Neil Armstrong biopic ‘First Man’ captures early spaceflight's terror

    First Man is not a movie about the moon landing.

    The Neil Armstrong biopic, opening October 12, follows about eight years of the life of the first man on the moon, and spends about eight minutes depicting the lunar surface. Instead of the triumphant ticker tape parades that characterize many movies about the space race, First Man focuses on the terror, grief and heartache that led to...

    Hundreds of dietary supplements are tainted with potentially harmful drugs

    From 2007 to 2016, the U.S. Food and Drug Administration flagged nearly 800 over-the-counter dietary supplements as tainted with potentially harmful pharmaceutical drugs, a study shows. Fewer than half of those products were recalled by their makers, scientists found. 

    Researchers analyzed the FDA’s public database of tainted supplements, identifying both the type of contaminating...

    Self-driving cars see better with cameras that mimic mantis shrimp vision

    To help self-driving cars drive safely, scientists are looking to an unlikely place: the sea.

    A new type of camera inspired by the eyes of mantis shrimps could help autonomous vehicles better gauge their surroundings, researchers report October 11 in Optica. The camera — which detects polarized light, or light waves vibrating on a single plane —  has roughly half a million sensors that...

    The first observed wimpy supernova may have birthed a neutron star duo

    A faint, fleeting supernova may be the key to understanding how neutron star duos are born.

    Astronomers have spotted what seems to be an ultrastripped supernova: a massive star in its death throes after its outer layers of gas have been siphoned off slowly by a compact companion such as a neutron star or black hole.

    “This is the first of its kind: the first ultrastripped supernova...

    Gene editing creates mice with two biological dads for the first time

    For the first time, researchers have created mice with two dads. No female contributed to the rodents’ genetic makeup.

    This unusual reproduction took place in a lab where researchers gathered fathers’ stem cells, and used them to produce embryos that were implanted into surrogate mothers. The technique required scientists to edit the animals’ genes in order for the mice to mature enough...
