Magnetic materials have traditionally been classified as either ferromagnetic, like the decorative magnets on iron refrigerator doors that are seemingly always magnetic, or antiferromagnetic, like two bar magnets placed end-to-end with opposite poles facing each other, canceling each other out so that the material has no net magnetism. However, there appears to be a third class of magnetic materials exhibiting what in 2022 was dubbed altermagnetism. Microscopically, magnetism arises from a collection of tiny magnets associated with electrons, ...

Magnesium compounds are a common ingredient of many remedies designed to help people wind down and escape the stresses of modern life. However, a new study has shown it is not only humans that are using forms of the chemical as a way to help them survive challenging conditions. In tests conducted on beaches in Cornwall, and in the laboratory at the University of Plymouth, scientists confirmed the findings of previous studies which showed large sandhoppers (Talitrus saltator) increase the levels of magnesium ions in their bodies as temperatures fall. This slows them down so they are less active than they would be during the warmer months. However, the new study has shown for the first time ...

New Haven, Conn. — The capacity to adjust beliefs about one’s actions and their consequences in a constantly changing environment is a defining characteristic of advanced cognition. Disruptions to this ability, however, can negatively affect cognition and behavior, leading to such states of mind as paranoia, or the belief that others intend to harm us. In a new study, Yale scientists uncover how one specific region of the brain might causally provoke these feelings of paranoia.  Their novel approach — which involved aligning data collected from monkeys with human data — also offers ...

Sweaty cows may not sound like the most exciting company, but in a warming world, researchers can’t get enough of them. When cattle are too hot, they tend to stop eating, said Raluca Mateescu, University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) professor in the department of animal science. This affects the cattle’s health and growth and threatens the longevity of the food supply coming from that herd. Climate change is making it more difficult to raise cattle – growth and reproduction are affected by heat – so ...

Virginia Tech’s Audrey Ruple and Courtney Sexton, already deeply involved in data collection and analysis for dog health and connections to humans through the Dog Aging Project, are imploring fellow scientists to cast the net even wider for data on the shared environments of humans and dogs in a perspective piece that appears this month in the journal Science. “Human environments and the impacts of environmental factors can vary substantially, and this variation should be captured by future studies of dogs to more accurately assess exposure risks for different and vulnerable populations,” ...

(Santa Barbara, Calif.) — The countries of the world agreed: Our planet needs more protection from human activity. And with the globe facing an assortment of environmental crises, they realized the plan needed to be ambitious. Thirty-by-thirty was their proposal: protect 30% of the planet by 2030. But while conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Three researchers at UC Santa Barbara have proposed a market-based approach to achieving the 30x30 targets in the ocean. They tested whether a system that allowed countries to trade conservation ...

This year has already seen massive heatwaves around the globe, with cities in Mexico, India, Pakistan and Oman hitting temperatures near or past 50 degrees Celsius (122 degrees Fahrenheit).   As global temperatures and urban populations rise, the world’s cities have become “urban heat islands,” with tight-packed conditions and thermal radiation emitting from pavement and skyscraper trapping and magnifying these temperatures. With 68 percent of all people predicted to live in cities by 2050, this is a growing, ...

Oregon State University researchers found that U.S. adults are fairly confident in linking wildfires and heat to climate change, but less confident when it comes to other extreme weather events like hurricanes, flooding or tornadoes. The recent study found that politics and personal experience played significant roles in people’s responses: Self-identified Republicans were less likely than Democrats to attribute extreme weather events to climate change, though Republicans who had personally experienced negative impacts from extreme weather events were more likely to link them to climate change than those who hadn’t. Looking at ...

The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study by the University of Barcelona, published in the Journal of Animal Ecology, shows that the extreme heatwave of 2022 caused an “unprecedented” increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgrí Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are “alarming ...
