Just a few minutes of getting out of breath each day could dramatically cut your risk of major diseases—including heart disease, dementia, and diabetes. A large study of nearly 100,000 people found that it’s not just how much you move, but how intensely you move that matters.
Scientists may have been unknowingly inflating microplastics pollution estimates, and the surprising source could be their own lab gloves. A University of Michigan study found that common nitrile and latex gloves release tiny particles called stearates, which closely resemble
Making babies in space may be more complicated than expected, as new research shows sperm struggle to navigate in microgravity. Scientists found that while sperm can still swim normally, they lose their sense of direction without gravity, making it harder to reach and fertilize
Far beneath the ocean near Japan, scientists have discovered that the magma system linked to the most powerful eruption of the Holocene is slowly rebuilding. By using seismic imaging, researchers mapped a large magma reservoir under the Kikai caldera and confirmed it is the
California's Bay Area may be a culinary hot spot for people, but food options for fish in the San Francisco Estuary have been limited and declining in recent decades. A new study from the University of California, Davis, shows there is a part of the estuary that is teeming with
Hygiene in everyday items that touch the body—such as clothing, masks, and toothbrushes—is critically important. The underlying principle of how graphene selectively eliminates only bacteria has now been revealed. In Advanced Functional Materials, a KAIST research team presents
Wildfire smoke is teeming with them. Researchers have employed them to develop energy-dense biofuels like rocket, marine, and jet fuels. Scientists have engineered rice paddies that interact differently with them, causing lower methane "burping." They can be used to extract
With artificial intelligence (AI) as an essential tool, San Diego State University researchers have discovered surprising similarities among ancient writing systems from Africa and the Caucasus region of Eurasia. Their study suggests that the Armenian alphabet may be more
Ribonucleic acids (RNAs) serve as messengers between DNA and protein production, and perform a wide variety of regulatory functions across different cellular processes. This makes them an interesting target for drug designers. Molecular genetics researcher Danny Incarnato
CERN scientists on Tuesday pulled off the unprecedented feat of transporting antiprotons by road, successfully test-driving the world's first antimatter delivery system, with an eye to one day supplying research labs across Europe.
While humans often struggle to find a partner who is both physically attractive and a reliable co-parent, yeast may already have cracked the formula for the perfect match. When choosing mates, these single-celled organisms tend to pick partners that may increase the chances of
Astronomers from the California Institute of Technology (Caltech) and elsewhere report the discovery of a binary system consisting of two brown dwarfs undergoing stable mass transfer. The detection of the system, designated ZTF J1239+8347, was made with the Zwicky Transient
For more than 40 years, the Golden State Killer haunted California. A serial rapist and murderer active in the 1970s and '80s, he eluded detectives for decades. By 2018, hope of identifying him was fading, until a woman—curious about her ancestry—spat into a plastic tube and
There is a place in northern Chile, 3,500 meters above sea level in the Andean Altiplano, where almost nothing survives. The Salar de Pajonales is a salt flat of savage extremes temperatures swinging from −23°C to 26°C, solar radiation among the highest measured anywhere on
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered an extrasolar planet orbiting TOI-4616—a nearby M-dwarf star. The newfound alien world, which received designation TOI-4616 b, is slightly larger than Earth. The
Neanderthals split into distinct regional groups that developed genetic differences far sooner than modern human populations typically did, according to a study published in Proceedings of the National Academy of Sciences. These findings were based on the analysis of a newly
Hair damaged by dyes, bleaching or harsh sunlight has just got special treatment. Green chemistry researchers at Flinders University are experimenting with plant-based oils to develop a promising new structural keratin-type repair application to reduce breakage and improve hair
The world is struggling to deal with ever-growing quantities of waste. A new World Bank Group report, What a Waste 3.0, shows that more than 2.6 billion tonnes of municipal solid waste (which includes rubbish from households, businesses and street cleaning) were generated in
Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some computationally demanding tasks. Despite their potential, as the size of quantum computers increases, reliably describing and measuring the
Some of the most ancient fossils collected to date were traced back to the Ediacaran period. This is the time interval ranging from around 635 to 541 million years ago, shortly before the time when scientists predict that a wide range of animals started appearing.
NASA is targeting April 1 to launch a crew of four astronauts on a journey around the moon that will set the tone for the agency’s lunar exploration ambitions
Neptune is the solar system's most distant planet, a cold, blue ice giant sitting nearly 30 times further from the sun than Earth. At that remote distance, temperatures plunge to nearly minus 200 degrees Celsius and a single year lasts 165 Earth years. Yet despite its
Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these devices work correctly and truly realize desired
More than 10,000 Starlink satellites currently orbit Earth. We see them crawling across dark skies, no matter how remote our location, and streaking through images from research telescopes.
Seals are carnivorous marine mammals that are well adapted to hunting for fish underwater, where visibility is poor. In such conditions, seals rely on their highly sensitive whiskers to detect tiny water movements left behind by swimming fish. Like rats and cats, seals also
One of the things astronomers find when they look around at galaxies is a correlation between a galaxy's mass and the mass of its supermassive black hole. Contrary to popular belief, these SMBH don't anchor their galaxies; they make up only a small portion of a galaxy's mass.
Scientists have finally found a hidden “critical point” in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal temperatures. The breakthrough was
A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in
Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests that the universe's rapid early expansion could have arisen naturally from a
General relativity stands as one of the bedrock theories in modern physics. Its strange view of relative time and space has been confirmed by countless experimental and observational tests, from rotational frame dragging to the radiation of gravitational waves. But there is
Every spring, Canadian beekeepers await the arrival of queen bees crucial to their industry. The queens that populate Canadian bee colonies through the season largely do not come from Canada at all.
In recent years, residents of Spain, France and the UK have looked up to see an eerie sight: deep orange sunrises and skies thick with a yellowish haze. These hazy skies often deposit "blood rain," rust-colored precipitation that leaves a fine grit on cars and windows.
Parks are vital public spaces. This is especially true if you're a parent with energetic children, or an office worker searching for a peaceful lunch spot.
Scientists have discovered that the ocean’s “missing” plastic hasn’t vanished—it has broken down into trillions of invisible nanoplastics now spread through water, air, and living organisms. These tiny particles may be everywhere, including inside our bodies, raising serious
A stranded humpback whale in Germany 's Baltic Sea looks weaker, and experts fear it won't be able to find its way back to the Atlantic despite several attempts at its rescue this week.
When an invisible entity making up 85% of the universe's mass stumps the greatest scientific minds of our time, awe is an understandable response.
As artificial intelligence (AI) tools become more common across government, new research from the University at Albany's Center for Technology in Government (CTG UAlbany) examines how agencies are using chatbots and what those tools are actually changing in practice.
Both winds and tides inject energy into the ocean. Much of that energy is then transported up to thousands of miles by internal waves: large-scale underwater waves that can travel between ocean basins. Quantifying the amount of energy transported by internal waves and assessing
This familiar phenomenon has puzzled researchers for centuries, but experiments are finally making sense of its unruly behaviors
After a stroke, the brain may do something surprisingly hopeful—it can “refresh” parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite, unaffected side can actually
A major new U.S. cholesterol guideline is shifting the focus toward earlier, more personalized prevention of heart disease. It urges people to start screening sooner—sometimes even in childhood—and highlights the importance of tracking not just LDL (“bad”) cholesterol but also
