In a new Nature Communications study, researchers developed a universal scaling framework for the strength of granular asteroids, showing that their tensile strength can be predicted from the size and shape of their constituent particles.
Animals fulfill a wide range of roles in human society. They provide food, contribute to scientific research, live alongside people as companion animals, and play important roles in education, conservation, research and public engagement through zoos.
Plastic is a wonder material that has molded itself to fit a wide variety of applications. But it comes with a host of drawbacks that aren't fully considered. That's why the United Nations has convened to hammer out a treaty to address plastic pollution.
Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists but true "flexitarians." A team led by microbiologists Bettina Glasl and Katharina Kitzinger from the University of Vienna, in collaboration with partners from Australia, has shown that, unlike
Wildfires in the Mediterranean region are becoming drastically more intense. The recent major fires in France, Spain and Greece show that firefighting efforts are reaching their limits.
Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common, these encounters compressed molecular gas, causing dense clouds to collapse under their own gravity and form new stars.
Governments across Australia have pledged hundreds of millions of dollars toward women's health services in recent months and years—but having more health services won't help if people don't know they're available or how to access them.
Augmented reality (AR) glasses, lenses thinner than a human hair, and holograms floating above your fingertips may sound like technologies from science fiction. At the heart of these emerging technologies, however, lies a nanoscale optical device known as a "metasurface."
Glassy polymers are those whose chains become immobilized below their glass transition temperature. The immobilized chains make them hard and stiff but also brittle, causing them to fracture when stretched. One promising strategy for overcoming this trade-off is to incorporate
Labor-intensive harvesting and complex processing make macadamias among the most expensive nuts in the world. This makes it all the more important to protect the trees from pests.
Some voting districts are tilted intentionally toward one party or another—a factor in the midterms. Geometry plays a critical role in gerrymandering
Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that are strong but slow or fast but weak. The trade-off
Revealing how proteins and end products of biological activity (metabolites) change within specific tissue functional units during development or in response to environmental factors is beneficial for understanding localized biological processes and the biological roles of
Two massive rock glaciers are creeping down mountain valleys in Alaska's Wrangell–St. Elias National Park. They sit only a few miles apart and formed under the same sky. One moves more than 5 feet (1.5 meters) a year. The other moves at less than half that pace.
For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, the team found that the giant star's inner atmosphere
The key to finding more critical minerals may lie in understanding how fluids and chemicals move through rock. As these fluids travel underground, they can dissolve, transport and concentrate valuable minerals in specific places.
The world is set to miss the 1.5°C global warming target, and plans are underway for U.N. climate talks in the Pacific and Turkey.

One Sunday morning, Juliet* woke up to a delivery driver with a large package that she had no recollection of ordering. She was quick to dismiss it as an e-commerce mistake before the card inside helped solve the mystery: "To Sober Juliet, from your friend, Drunk Juliet."
Experts say there is not enough evidence to support broadly screening men for testosterone without any symptoms
A new study led by researchers at the University of California, Santa Cruz, has overturned decades of assumptions about Miracinonyx trumani, the extinct predator popularly known as the American cheetah. By analyzing nuclear paleogenomes and stable isotopes from fossils found as
The majority of money laundering arrests involve people under 30, a new analysis has found.
Ancient DNA confirms Miracinonyx trumani was more closely related to modern pumas than cheetahs and had a more varied diet than previously thought.
And, unlike African cheetahs, it was a flexible carnivore The post The Extinct “American Cheetah” Wasn’t a Cheetah After All appeared first on Nautilus .
A private spacecraft that was supposed to supply a lifeline to NASA's Swift Observatory managed to get close to the sinking telescope and even snap photos more than a week after the rescue was abandoned.
Patents are far more than legal documents protecting intellectual property. They are a vast source of scientific information about chemicals under development, often years before they appear in products or in the environment. That makes patents a valuable data source for early
Fungi are major degraders of plant biomass, including leaves, stems and roots. Investigating the molecular mechanisms that control this process is essential for identifying ways to degrade and use lignocellulose, a recalcitrant waste-product residue from biofeedstocks and
Some of the most intriguing scientific breakthroughs happen when researchers aren't explicitly looking for them. Take, for example, the pygmy raccoon (Procyon pygmaeus), a critically endangered species that lives only on Cozumel Island, Mexico. Scientists were observing them
