    A chemistry card game forges bonds

    The new strategy-based card game Ion makes a game out of chemistry. It challenges players to group positively and negatively charged ions to form compounds. Players pass around ion and noble gas cards to build the compounds and collect sets of noble gases for points.

    New to chemistry? Never fear. The card game relies on basic arithmetic of positive and negative charges to create neutral...

    Pots from hunter-gatherer site in China tell tale of lifestyle shift

    East Asia’s first farmers didn’t transform ancient foraging cultures as much as researchers have traditionally thought. That’s because roving groups of foragers adopted sedentary living habits first.

    New evidence suggests that hunter-gatherers living on China’s central plain made pottery and formed permanent settlements between 10,500 and 10,000 years ago, hundreds of years before a...

    City- and country-dwelling microbes aren’t so different

    Deep breaths of country air might feel fresh and clean compared to the polluted city. But city or country, you’re probably sucking in similar microbes. 

    Citizen scientists in the Wild Life of Our Homes project took 1,200 dust swabs from outdoor doorways and sent them to scientists that the University of Colorado, Boulder. Researchers...

    Ritual cannibalism occurred in England 14,700 years ago

    A grisly ritual, at least by modern standards, played out in a British cave about 14,700 years ago.

    Hunter-gatherers took the bodies of at least six of their deceased comrades to what’s now called Gough’s Cave and ate them as part of a burial rite, say biological anthropologist Silvia Bello of the Natural History Museum in London and her colleagues. Microscopic analyses show that these...

    Sometimes it’s best to feed the trolls

    If you’ve been to the Internet, you’ve probably encountered a troll. That’s the nickname given to the people behind nasty or inflammatory posts in online outlets. Trolls seem to revel in sowing discord, provoking and tormenting other readers. “Don’t feed the trolls” is often considered the best response for dealing with such commenters, and data suggest that it’s effective: A recent Pew...

    To reduce stress and anxiety, make yourself invisible

    Turning someone invisible may still be the stuff of fiction, but what would invisibility feel like? Perhaps unsurprisingly, it makes people less anxious about social situations, researchers find April 23 in Scientific Reports.

    To create the sensation of being invisible, scientists designed a virtual environment that...

    Lit-up gas clouds hint at galaxies’ violent pasts

    Voorwerpje
    \FOHR-vehrp-yuh\ n.

    An intergalactic gas cloud still glowing after being blasted by ultraviolet radiation from a neighboring galaxy.

    Great globs of galactic gas are a fading reminder of a more vigorous past for some galaxies. Eight of these gas blobs, known as voorwerpjes (after the Dutch word for little objects), lie next to galaxies that show evidence of recent...

    Astronomers celebrating Hubble’s past focus on its future

    BALTIMORE — A technique for sniffing around in the atmospheres of supersized planets near super bright stars could also help the Hubble Space Telescope unravel the history of the universe.

    Hubble scientists developed a way to slowly scan the sky while collecting starlight so the telescope could explore the neighborhoods of stars that would otherwise be too bright for its sensitive...

    A peer-reviewed study finds value in peer-reviewed research

    The modern scientific process is guided and determined by peer review. A group of scientists in the field read and scrutinize a scientific manuscript before it is published. Committees of experts review plans for studies and determine whether they should be funded. The National Institutes of Health, National Science Foundation and the European Research Council distributed nearly $40 billion...

    Gene in human embryos altered by Chinese researchers

    Chinese researchers have genetically modified a gene in nonviable human embryos. The controversial work illustrates that many hurdles remain before gene editing to correct genetic diseases would be safe for clinical use, the team reports April 18 in Protein & Cell.

    The researchers used gene-editing...
