Farmers around the world are struggling with the impact of climate change, financial pressures and depleted soil—and industry experts say bringing consumers closer to the people who produce their food could provide a solution.
Chemical reactions at surfaces play a central role in many processes, including catalysis and materials synthesis. It is well known that the outcome of these reactions is influenced by the translational, vibrational and rotational motions of atoms and molecules. Now, a study shows that electron spin, another fundamental property of matter, also influences how chemical reactions at surfaces unfold.
Weather forecasts rely on many different kinds of data, including temperature, humidity and wind. For the first time, researchers, including those at the University of Tokyo, have demonstrated that a long-theorized improvement to weather models—adding data on water isotopes in the atmosphere—does work. They showed that incorporating satellite measurements of water vapor isotopes into weather models improves forecasts of atmospheric conditions for up to five days, including predictions of heavy rainfall in many regions.
Technology companies are stepping up their climate commitments but not fast enough to counter rapidly growing energy needs linked to the artificial intelligence boom, a report said Wednesday.
A rare trio of hurricanes were churning through the Pacific Ocean on Thursday, which scientists attributed to waters warmed by a historically strong El Niño phenomenon.
Researchers in Chile have designed an unlikely new garment for injured penguins—snug red vests threaded with copper and zinc that they hope will help the aquatic birds heal faster.
A study provides the first large-scale empirical evidence that seagrass meadows act as a critical safety net for millions of coastal people living in extreme poverty across the Indo-Pacific.
For children born with cleft lip and palate, repairing gaps in the jawbone often means waiting until they are 10 to 12 years old before undergoing invasive bone graft surgery. University of Sydney researchers have developed a biodegradable "nanobone" material that allows the body to harness its own healing properties to regrow bone, offering a potential future alternative to procedures that have changed little in more than 50 years.
A new report from the American Psychological Association warns that student engagement with educational technology is not the same as learning—and that generative AI tools pose particular risks by improving students' immediate performance without building their underlying knowledge or skills.
An updated analysis of U.S. homicide data has found that intimate partner violence (IPV) often precipitates mass homicide and is also frequently associated with multi-victim and single-victim deaths. The study categorizes homicides into single-victim, multi-victim (2–3 victims) and mass (4 or more victims, excluding the perpetrator) fatalities, revealing distinct demographics and circumstances. The findings of the study published in Annals of Epidemiology, can help inform the development of tailored strategies to prevent homicide.
