Beneath Antarctica's Ross Ice Shelf lies one of the least measured oceans on Earth—a vast, dark cavity roughly twice the volume of the North Sea.
A new study reveals that people are far more emotionally affected by anticipating negative future outcomes than by imagining positive ones, helping to explain why many individuals avoid uncertainty and prefer decisions to be resolved sooner rather than later.

Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in global species conservation. This is the central finding of a new international
Physicists from University of Jyväskylä and Aalto University (Finland) have experimentally realized a two-dimensional topological crystalline insulator. This is a quantum material that has been theoretically predicted for more than a decade but had remained inaccessible due to

Type 2 diabetes becomes more dangerous to the heart the longer a person has it. Researchers found that after several years, red blood cells can begin interfering with healthy blood vessel function. This harmful shift was not present in newly diagnosed patients but emerged over
Giant ancestors of modern-day kangaroos—which previous research has estimated could weigh up to 250 kilograms—may have been able to hop in short bursts, according to research published in Scientific Reports.
Mining companies worldwide are expanding mineral extraction at existing mines, as the rate of opening new sites slows, to meet global demand driven mainly by the need for clean energy infrastructure.
Brain scans show a spot in the cerebellum attuned specifically to words, expanding on studies that point to the region's importance for language.
As America approaches its 250th anniversary of declaring independence, NASA's Artemis II mission will carry a host of mementos that reflect the nation's long tradition of exploration, innovation, and leadership in its official flight kit. The items will fly aboard the Orion
Every time we speak, we're improvising. "Humans possess a remarkable ability to talk about almost anything, sometimes putting words together into never-before-spoken or -written sentences," said Morten H. Christiansen, the William R. Kenan, Jr. Professor of Psychology in the
Lysosomes are membrane-bound organelles whose acidic lumen (pH 4.5–5.0) is required for degradation. This luminal acidity is known to regulate cytosolic-side functions such as membrane fusion/fission, movement, and membrane-contact site formation.
Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to scientists at the University of Surrey.
Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that this ring is too strict: on tidally locked worlds that keep one face in
Scientists have created 3D printed surfaces featuring intricate textures that can be used to bounce unwanted gas particles away from quantum sensors, allowing useful particles like atoms to be delivered more efficiently, which could help improve measurement accuracy.
Four in five women musicians have experienced sexual violence and harassment while working or taking part in the Scottish folk music scene, according to new survey findings.
A new blood test may reveal Crohn’s disease years before symptoms begin. The test detects an unusual immune response to gut bacteria in people who later develop the condition. By studying healthy relatives of Crohn’s patients, researchers identified early warning signals long
A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Their new study has revealed that Earth's massive drop in temperature after the dinosaurs went extinct could have been
Living walls—structures housing flowers and plants fitted to the outside of new and old buildings—can significantly enhance the biodiversity within urban environments, a new study has shown.
University of Queensland researchers say the discovery of a new stress reduction role for a naturally occurring molecule in the body could lead to new drugs and treatment for metabolic disorders and aging.
Despite being one of the most cooperative species on the planet, humans routinely fail to manage shared resources sustainably. We overfish from the oceans, burn fossil fuels, and over-prescribe antibiotics; behaviors that offer individualistic short-term benefits, but result in
A new study reveals that super agers over 80 have a distinct genetic edge. They are much less likely to carry the gene most associated with Alzheimer’s risk, even when compared with other healthy seniors. Researchers also found higher levels of a protective gene variant in this
Countries with a stronger market orientation may experience lower rates of homicide, according to a new study from the University of Georgia.
Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or flowers. And unlike trees, they had no true root
For 450 million years, plants and soil fungi have been trading partners. The fungi weave through plant roots, delivering phosphorus and other soil minerals in exchange for sugars and fats produced by the plant through photosynthesis. This ancient collaboration supports roughly
Scientists have long focused on quantifying fear and other negative emotions in animals. Now they’re trying to measure positive feelings — and it’s a challenge.
Scientists found that nasal cells act as a first line of defense against the common cold, working together to block rhinovirus soon after infection. A fast antiviral response can stop the virus before symptoms appear. If that response is weakened or delayed, the virus spreads
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet orbiting a sun-like star. The newfound alien world, designated TOI-3862 b, turns out to be a dense super-Neptune exoplanet. The finding is
