Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine the benefits of the two existing types of magnetism, ferromagnetism and antiferromagnetism, ultimately reducing or
Some cynodonts may have been giving birth to live young much sooner in evolutionary history than previously assumed. A new Frontiers in Mammal Science study has offered the first compelling evidence that cynodonts may have been viviparous—a reproductive mode characterized by
Growth rings on a fossil bone suggest at least one mammal ancestor gave birth to live young rather than laying eggs 236 million years ago.
Every day, millions of liters of polluted water flow through many South African rivers and disappear into the sea.
New EU restrictions on toxic substances known as "forever chemicals" in food packaging kicked in Wednesday, along with broader rules aimed at cutting packaging waste in the bloc.
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising CO2 levels and shifting rainfall patterns are likely to
Scientists have crossed an important line in biological engineering. In a recent study, researchers used artificial intelligence to design complete sets of genetic instructions for bacteriophages, viruses that infect bacteria. Some of those computer-generated designs produced
Venous malformations are abnormally shaped veins that develop when the cells lining blood vessels grow too fast when they aren't supposed to. Children can be born with them, and as the child grows, the venous malformations can get bigger. Venous malformations are a type of
With approximately one-third of the world's population living within a day's walk of a coastline, sea-level rise poses a serious global threat. Every centimeter of sea-level rise could displace 1.5 million people, and current estimates range from half a meter (1.6 feet) to 2
A study involving more than 58,000 adolescents from 21 countries found that "unstructured free time"—defined as periods without adult supervision or activities guided by educational, cultural or athletic goals—is strongly associated with delinquent behavior and exposure to
Looking inside a newly discovered ancient tomb for the first time is both exciting and terrifying. I was fortunate to experience this recently as director of an international research team carrying out fieldwork in the Theban necropolis, a UNESCO World Heritage Site near the
MXenes are two-dimensional materials made of very thin layers of metals, measured on the atomic scale. They conduct electricity well and have surfaces that can easily interact with other materials, making them excellent candidates for advanced electronic devices, computers and
It's common to see images of astronauts on the International Space Station exercising, running on special treadmills and pedaling cycles designed for tight quarters.
Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for flexoelectricity, a phenomenon in which a material generates an electric charge when it bends unevenly. The findings are published in
Astronomers have captured an unprecedented image of a cosmic recycling project in progress—fragments of a dying star being busted up, stripped and absorbed into interstellar space.
Peatland fires in Indonesia pose a major threat to habitats, wildlife and people. That risk is exacerbated by the country's periodic El Niño warming phases, which bring prolonged drought.

The severe, drought-fueled fires now burning across much of the American West and Canada may be scorching forests so thoroughly that they cannot recover to the forests they once were, new research shows. A study by Colorado State University, Western Colorado University and
For many people, the fear of venomous snakes is linked to one thing: pain. Yet new research led by scientists at Bangor University suggests that, for Europe's vipers, at least, causing pain may never have been a driving force in the evolution of their venom.
University of Birmingham scientists who used green chemistry to make a next-generation metal-organic framework (MOF) for capturing heavy metals from wastewater have shown that it is cheaper and more resource-efficient to produce than a similar MOF processed conventionally.
Military leaders frequently underestimate how big the wars they engage in will get. Gen. Douglas MacArthur predicted U.S. troops could come home from the Korean War in time for Christmas, just months after the conflict started. But Chinese attacks that winter extended the war
In Nature Communications a research team led by Professor Tae-Hyun Bae of the KAIST Department of Chemical and Biomolecular Engineering introduced hydrogen-selective transport pathways at the angstrom scale inside polymer membranes and clarified their separation performance
The building blocks of rocky planets may have begun forming just 100 million years after the Big Bang—long before the first galaxies even existed—according to new research from the University of Portsmouth.
Most antibiotics used clinically are based on natural compounds produced by bacteria and other microorganisms. At the Helmholtz Institute for Pharmaceutical Research Saarland (HIPS), researchers are using soil-dwelling myxobacteria as a source of new active ingredients. They
Last year, we described Agrilo, an affordable "colorimetric" soil-testing system developed through research at MacEwan University. Using a smartphone camera to interpret color changes, Agrilo measures soil nutrients and can provide farmers with timely guidance to support
In a retrospective study, people taking estrogen-only hormone therapy for menopause were less likely to see signs of dementia
New research involving the University of Liverpool has provided comprehensive insights into the largest flood event in Europe over the past millennium—the flood traditionally known as "St. Mary Magdalene's Flood" of 1342.
The DNA of Asian elephants tells a concerning story. Although all four subspecies are under pressure, there are considerable differences in their genetic health. In an article published in the journal Genome Biology and Evolution, researchers show how whole-genome analyses can
Scorching heat waves, severe cold snaps and other extreme weather events are limiting where species can exist—and affecting biodiversity estimates—for more than 500 North American bird species, according to a new, Yale–led study. The issue is particularly acute in the Great
In collaboration with the University of Vienna, the Technical University of Munich (TUM), and Heidelberg University, researchers at the TUD Dresden University of Technology have developed an innovative tool that significantly simplifies lipid research. The new open-source

Researchers are developing biotechnological processes that enable microbes to produce proteins and vitamins for human consumption using basic chemical ingredients, such as carbon dioxide, hydrogen and oxygen—entirely bypassing livestock farming and agriculture. Because these
Municipal regulation of short-term rentals "is low-hanging fruit" that helps improve housing affordability, a new study by McGill researchers suggests. The research shows that rents were relatively lower in Canadian municipalities that imposed restrictions on when and how
From a partial eclipse over Berlin to totality over Spain, see some of the incredible images of the August 12 total solar eclipse
For dogs with heart disease, a fraction of a centimeter can make a life-changing difference. Veterinarians often rely on chest radiographs to monitor subtle changes in heart size that help determine when treatment should begin. But those measurements can vary from one doctor to
Ancient trees—those that are remarkably old for their species—are declining worldwide, raising concerns about the loss of the ecological and evolutionary history they represent. Their exceptional longevity has long encouraged the idea that they act as genetic reservoirs,
Spectacular images of lava flowing down the slopes of erupting Mount Etna have drawn flocks of tourists to the Italian volcano—to the concern of local guides.
Scientists from Brazil and other countries have discovered a new species of frog in the flooded forests of the western Amazon. They named it Adenomera varcena. This finding significantly advances our understanding of Amazonian biodiversity and cryptic diversity, or cases in
To date, close to 30,000 satellites have been launched into Earth's orbit, leading to mounting concerns over the debris created when they collide. In a new analysis posted to the preprint server arXiv, Hugh Lewis of the University of Birmingham shows that satellite
On the surface, credit rating agencies simply score a company's financial health. They look at a business's equity and debt and diagnose how risky it is for investors. They slap on a letter grade to show how likely it is to repay its debts.
One of nature's greatest spectacles—a rare total solar eclipse—cast its shadow on Wednesday, briefly turning day into night in Russia's remote Arctic north and western Iceland before heading toward mainland Europe.
More than 70% of massive stars are born in close binary systems, where gravitational tugs and mass transfer between companions dramatically alter their evolution. Yet once the interaction ends—whether through mass transfer, merger or the supernova explosion of one partner—the
