    Prosecco production takes a toll on northeast Italy’s environment

    Sorry to burst your bubbly, prosecco lovers, but skyrocketing demand for the sparkling wine might be sapping northeastern Italy’s vineyards of precious soil — 400 million kilograms of it per year, researchers report in a study posted online January 10 at bioRxiv.org

    That’s a lot of soil, but not an anomaly. Some newer vineyards in Germany, for example, have higher rates of soil loss,...

    Bacterial compounds may be as good as DEET at repelling mosquitoes

    Molecules made by bacteria keep mosquitoes at bay. The compounds are a newfound potential stand-in for DEET, a ubiquitous chemical used in most commercially available mosquito repellents in the United States.

    In lab tests, the molecules were as effective as DEET in stopping Aedes aegypti mosquitos, which can carry Zika, dengue and yellow fever, from snacking on artificial blood,...

    Here’s how the record-breaking government shutdown is disrupting science

    As the partial federal government shutdown enters its fourth week — on January 12 becoming the longest in U.S. history — scientists are increasingly feeling the impact. Thousands of federal workers who handle food safety and public health are furloughed. Countless projects researching everything from climate change to pest control to hurricane prediction are on hold.

    Among government...

    Poison toilet paper reveals how termites help rainforests resist drought

    It took hundreds of teabags and thousands of rolls of toilet paper for tropical ecologist Kate Parr and her colleagues to demonstrate that termites help tropical rainforests resist drought. Forests with more termites show more soil moisture, leaf litter decomposition and seedling survival during a drought than forests with fewer termites, the scientists report January 10 in Science.

    The...

    Beer today, gone tomorrow

    Rising temperatures and more frequent droughts could cut barley crop yields worldwide by the end of the century, leading to beer shortages and high prices, Jennifer Leman reported in “Add beer to the list of foods threatened by climate change” (SN: 11/10/18, p. 5).

    Online reader Jean Beaulieu was hopeful that scientists will figure out an easy way to grow...

    DNA tests of Lassa virus mid-outbreak helped Nigeria target its response

    When an outbreak of a viral hemorrhagic fever hit Nigeria in 2018, scientists were ready: They were already in the country testing new disease-tracking technology, and within weeks managed to steer health workers toward the most appropriate response.

    Lassa fever, which is transmitted from rodents to humans, pops up every year in West Africa. But 2018 was the worst season on record for...

    A new way to genetically tweak photosynthesis boosts plant growth

    A genetic hack to make photosynthesis more efficient could be a boon for agricultural production, at least for some plants.

    This feat of genetic engineering simplifies a complex, energy-expensive operation that many plants must perform during photosynthesis known as photorespiration. In field tests, genetically modifying tobacco in this way increased plant growth by over 40 percent. If...

    Poop provides a link in determining penguin diet from space

    The best way to find out what an Adélie penguin is eating is to catch it and make it regurgitate its meal. This is about as pleasant for bird and researcher as you might think. It’s also invasive, time-consuming and expensive to do on a large scale, so scientists need other ways to determine diet. Now they have one; it relies on images taken by Landsat satellites.

    The satellites don’t...

    This scientist watches meat rot to decipher the Neandertal diet

    WASHINGTON — Kimberly Foecke has a great relationship with her local butcher.

    Though she buys loads of meat, Foecke is not a chef or the owner of a small zoo. She’s a paleobiologist who studies what Neandertals ate. And that involves, in her words, “experimental putrefaction, which is a fancy way of saying, I rot meat, all day, every day.”

    Scientists know Neandertals ate a lot of...
