Fourth-year veterinary students matched—and experienced clinicians outperformed—an AI-enabled digital stethoscope in diagnosing heart murmurs and arrhythmias in cats and dogs, according to a new study from North Carolina State University. The study emphasizes the importance of
University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. 12, in The Journal of Immunology, offers a major step
Online conflict tends to advance social movements rather than undermine them, according to new research from McGill's Desautels Faculty of Management.
Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient option—if scientists can tame them.
A new study is offering insights into a crucial period of child development The post Loner Kids May Be Happier Than You Think appeared first on Nautilus .
Place-based decarbonization schemes designed to help communities become more sustainable must involve local people earlier and consider the range of different community responses in their development if they are to be successful and gain fuller community support, researchers
Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.
The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. However, as soon as nanoparticles come into
Before tropical cyclones can significantly strengthen, they generally must first become vertically aligned, with their rotating centers stacked through the atmosphere. New research using nearly three decades of NOAA Hurricane Hunter observations identifies four features that
River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make up less than 1% of Earth's total navigable waterways.
From the American West to Europe, droughts are drying up rivers, fueling destructive fires and reshaping ecosystems. They are also changing the spread of infectious diseases, leading to surges in illnesses like cholera and West Nile virus around the world.
Tropical forests store enormous amounts of carbon and harbor most of the world's terrestrial biodiversity, but scientists fear that increasingly severe droughts threaten their ability to survive and continue absorbing carbon from the atmosphere. A new study published in Nature
Little red dots have puzzled astronomers since their discovery in James Webb Space Telescope (JWST) data from the universe's deep past. Their "powering engines" might resemble a newly discovered phenomenon dubbed a "black hole star"—an early, rapidly growing black hole wrapped
Much like an indecisive single person on a dating app, female treefrogs struggle to pick the most desirable mates when they have too many options to choose from. According to a new study published Aug. 12 in the journal iScience, when female Cope's gray treefrogs gather around
In the lab, female frogs were less likely to choose preferred males as mating calls increased, potentially giving other males a better shot.
A new study of the Helix Nebula shows a never-before-seen detail of how dying stars recycle elements. Researchers found it by accident
There’s a million-dollar prize for proving the Riemann hypothesis. Claude couldn’t pull that off, but it made significant progress on a related problem
First glimpsed as “little red dots” in deep-space images from the James Webb Space Telescope, these giant, gas-shrouded black holes are full of surprises
In a rare study of snakes as nest predators, scientists found nesting birds were loath to strike rattlesnakes even though they likely had no previous experience with vipers.
The North Dakota Agricultural Weather Network—known as NDAWN—isn't just measuring precipitation amounts and temperatures across the state. It's also playing a role in developing tools for crop disease management.
According to new research, viewers often dismiss, trivialize or even romanticize signs of cat distress during "play" interactions, raising concerns for cat welfare.
Scientists at the Center for Molecular Medicine Cologne (CMMC) and the CECAD Cluster of Excellence on Aging Research have demonstrated in a biomedical study that ribosomes, the protein factories of our cells, face an unusually tough challenge when building large,
In the Arctic, weather plays a key role in determining how much ice covers the ocean. Arctic cyclones are one weather phenomenon with a significant influence, causing unusually warm and stormy conditions that typically lead to significant ice loss. These conditions last
A study involving the Cluster of Excellence ECONtribute at the Universities of Bonn and Cologne demonstrates that not only retail investors but also financial professionals often assess potential stock market returns differently from what standard financial economics models
A massive new first-of-its-kind study zooms into the neighborhood level The post There’s No Link Between Crime and Unauthorized Immigration appeared first on Nautilus .
An international team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has identified three actively accreting supermassive black holes in the galaxy J0148-4214. Matter is falling into the black holes from accretion disks surrounding them.

Quantum advantage refers to the point at which a quantum computer solves a clearly defined task faster or more efficiently than any classical computer—or makes it solvable in the first place. For many practical applications, this has not yet been demonstrated. Research
The Amish, a Christian denomination and a three-century-old ethnic group of German migrants known for its strict lifestyle standards, are one of the fastest-growing minority populations in the U.S. For more than a century, the number of Amish people—whose American lineage
You walk in a park. Children are playing, people are walking their dogs, and then you hear someone say, "Who's my little sweetie?" You turn around expecting to see a stroller. But someone is sitting beside a dog, speaking in the same voice they would use with a baby.
Most glues need a dry surface to stick properly. Bonding materials underwater is challenging because water forms a thin film on any surface, so instead of an adhesive touching a material directly, it touches a layer of water, which weakens the bond. But scientists from China
The surface of the moon is a bleak and forbidding place that could be hiding a lot of water ice within its dusty landscape. However, most possible ice deposits don't just stand out in an image. Scientists need specialized mapping to find those deposits, so they have devised
Bumblebees are able to learn to associate new odors with their colony's queen, instead of being preprogrammed to recognize the queen's pheromones from birth, according to a new study led by researchers at Penn State. For the study, published in the journal Communications
They may look like any ordinary species of flies buzzing around on any given day, but the New World screwworm is quite extraordinary. Screwworm flies are highly destructive parasitic flies that feed on the tissue of warm-blooded animals, including humans (though the risk to
The Western U.S. is experiencing periods of increasingly intense drought, and higher temperatures are exacerbating the issue by drawing even more moisture from plants and soils into the atmosphere. The results can be seen in the ever-expanding wildfire footprint, with many of
Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity at higher temperatures.

With extreme weather increasing around the world, scientists are working to help critical infrastructure, such as water management systems, adapt. On the U.S. West Coast, where both periods of prolonged drought and intense atmospheric river storms are common, effective water
A dangerous cocktail of tectonic positioning, loose earth and shoddy construction contributed to the unprecedented damage caused by Venezuela's twin earthquakes, experts say.
