    How a small amount of rare earth metal shapes the environmental impact of magnets

    Magnets for electric cars and wind turbines contain only a small amount of the rare earth metal dysprosium. Yet, this metal is responsible for a large share of the environmental impact and costs, according to research by environmental scientists Stellina Samuel, Robert Istrate and René Kleijn. The study is published in the journal Sustainable Production and Consumption.

    Ancient altercations between musk turtles and alligator gar recorded in Florida's fossil record

    Sometime between 5.5 and 5.6 million years ago, two shell crushers squared off in the languid currents of an ancient Florida river. The fossils they left behind, discovered by paleontologists at the Florida Museum of Natural History, reveal the identity of the combatants and the outcome of their encounter.

    First-of-its-kind AI tool for translating life-saving weather warnings across the US advanced

    Nearly 69 million people in the United States speak a language other than English at home, yet weather warnings have long been issued almost exclusively in English. A new study documents how the National Weather Service is using artificial intelligence to change that, developing a comprehensive translation program that delivers life-saving forecasts and alerts in Spanish, Chinese, Vietnamese, Samoan, French and other languages.

    Antibiotic resistance turns up in Australian horses, raising new concerns about animal and human infections

    Research into a common environmental germ that can cause severe infections in people and animals has raised concern that horses are starting to develop antibiotic resistance towards it. The University of the Sunshine Coast study examined the prevalence of the bug P. aeruginosa in Australian wild birds, native wildlife, livestock and domestic animals.

    Twilight hunt reveals falcon feasting on unusual prey at Greek lagoon

    Falcons are lauded for their speed and agility. The Eurasian Hobby (Falco subbuteo), skilled at snagging birds and insects out of the air, is no exception. However, during twilight on one day in October, researcher Apostolos Christopoulos observed several hobbies feeding on something else in a protected wetland in Greece—bats from the genus Pipistrellus.

    'Mini-Neptune' exoplanets may have smoggy atmospheres similar to diesel exhaust

    The astronauts circling Earth on the Artemis mission sent back beautiful clear photos of the continents, clouds, and oceans. But we might be the exception. Many planets in the universe may be hazed in clouds of soot, according to a new study by University of Chicago scientists. Their analysis explains a curious trend seen by astronomers training telescopes on distant planets beyond our own solar system. Many of these worlds had atmospheres that returned strangely featureless readings.

    How a Richard Feynman formula could explain your dining habits in a new city

    One of the dilemmas facing anyone in a new and unfamiliar city is where to dine out. You might consult guides, speak to locals, check reviews, and ultimately, try your luck. But if you're there for a while, at some point you're going to be asking yourself whether to visit new eateries or stick to the ones you've already tried and liked.

    Atacama Desert's extreme aridity initiated 20 million years earlier than previously thought, study finds

    A collaborative study with the University of Cologne, recently published in Nature Communications, provides compelling evidence that the extreme aridity in the hyperarid core of the Atacama Desert began over 40 million years ago—significantly earlier than previously assumed. The findings require a reconsideration of how deserts form and offer a new perspective on the long-term evolution of Earth's most extreme environments. Researchers from SUERC Centre for the Isotope Sciences are co-authors of a study which casts new light on the history of Earth's driest region, the Atacama Desert in Chile.

    Modeling life beneath our feet: A step towards realistic soil ecology at the landscape scale

    As soil health becomes a defining goal of the EU Soil Strategy for 2030, researchers at Aarhus University are rethinking how we model what lives beneath our feet. Their new spatially explicit population model for the soil invertebrate Folsomia candida (springtails) marks a significant step beyond standard laboratory testing.

    The risk of relationship breakdown can be influenced by our genes

    Genetics influences who of us are more likely to experience a relationship breakdown, and who are more likely to remain together. But genes are not decisive, new research shows. "Our destiny does not lie in our genes, but if a relationship were a jigsaw puzzle, our genetics would make up some of the pieces that can influence the risk of a breakup," says sociologist Ruth Eva Jørgensen.

    Budget-friendly, lab-grown steak with realistic texture

    A team of Israeli scientists at the Hebrew University of Jerusalem has developed a novel method to significantly lower the production costs of cultivated meat. The new study demonstrates that preloading plant-derived cellulose scaffolds with growth factors supports the cost-efficient proliferation and differentiation of bovine stem cells. By binding these vital proteins directly to an anisotropic, directionally frozen framework instead of dispersing them in liquid media, this method achieves high-quality tissue development using up to 10 times fewer expensive factors. Upon multi-week cultivation and subsequent pan-frying, the cell-bound constructs show partially similar mechanical and visual responses to traditional sirloin cuts.

    From flat moss to forests and flowers: Protein discovery may explain how plants conquered land

    If plants had never learned to grow in multiple directions, our world would look very different. No trees, flowers, or other complex plants—and therefore no animals or humans. New research from the University of Copenhagen now suggests that a specific protein in moss may have been crucial for this key step in plant evolution—a step that made life on land possible.

    How Macau strengthened its typhoon resilience without massive seawalls

    Nonstructural disaster measures, including early warnings and evacuation systems, helped improve coastal resilience and reduce storm-surge impacts in Macau, report researchers at Science Tokyo. After analyzing the city's responses to three major typhoons, which included resident interviews, evaluations of early warning systems, evacuation procedures and other typhoon mitigation efforts, the study found that earlier issuance of typhoon warnings, color-coded storm-surge alerts and government-led evacuation guidance significantly improved public trust and reduced disaster impacts.

    Flatworms reveal exploding immune cells that kill surrounding tissue

    Stanford scientists have discovered a new type of immune cell that kills surrounding cells via explosion—a cellular detonation so fast and complete that the cell vanishes within minutes, leaving no trace behind. This discovery comes from an unlikely source: planarian flatworms. These aquatic, slithering pancake versions of worms are famous for their ability to survive dismemberment and grow whole new organisms from the sliced-up segments of their formerly unified body. Understanding how these flatworms' immune systems have managed to endure for hundreds of millions of years could hold important insights for modern medicine.

    Tiny membrane tethers revealed as key to plant cell survival in drought

    Water deficit resistance in plants has long been a topic of interest for cultivating reliable crops. Some plants can alter their above-ground structure to lock in moisture, while others develop deep, industrious roots that find hard-to-reach water sources. While such responses are obvious to the naked eye, we know little about how responses to environmental stress occur at the microscopic, cellular level.

    Predicting physics without parameter tuning: A faster computational approach

    Numerical simulations in physics often require estimating a multitude of parameters, making the process computationally expensive and complex. Researchers at University of Tsukuba have introduced a new method called the multiparameter eigenvalue-problem emulator, enabling reliable predictions based directly on relationships among known data by eliminating the need for parameter estimation. This innovation considerably reduces computational costs and enables systematic quantification of predictive uncertainty.
