Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank
Scientists at McGill University have found a way to supercharge the immune system’s natural killer (NK) cells, helping them break through the defenses tumors use to stay alive. By temporarily blocking two proteins, researchers turned these cells into far more effective cancer
Scientists at UT Southwestern have uncovered a surprising new “master switch” that helps control how much cholesterol the liver sends into the bloodstream. The newly identified protein, HELZ2, works by shutting down the genetic instructions needed to produce apoB — a key
Located in the middle of the North Pacific, between Japan and Canada, lies one of the world's largest oceanic plateaus, the so-called Hess Rise. The plateau is roughly T-shaped and extends over a length of about 1,000 kilometers. Due to its distance from the nearest mainland,
The Galápagos Islands off the coast of Ecuador are home to more than a thousand plant and animal species found nowhere else on Earth—things like marine iguanas and giant tortoises. In a new paper in the journal Zootaxa, scientists have announced the discovery of the newest
Thousands of holes are appearing in the Pennine hills, as part of efforts to improve carbon storage by restoring damaged peatland.
Imagine walking along Ipanema beach on a summer afternoon. The sand is golden, there's a cooling sea breeze, the shade of a parasol and a cold drink in hand. Now look up.
The buildup of a protein called 𝛂-synuclein (ASN) into toxic clumps is a hallmark of synucleinopathies, a group of neurodegenerative diseases that includes Parkinson's and multiple system atrophy (MSA). These aggregates are associated with cellular dysfunction and lead to
Women politicians are significantly more likely than their male colleagues to refrain from speaking out in public for fear of threats or harassment—particularly on issues relating to migration and gender equality. Politicians with an immigrant background are also more likely to
Magnetic switching processes are considered a prime example of controllable physics at the nanometer scale: in certain thin-film systems, a short electrical current pulse is sufficient to reverse the magnetization in a targeted way. The underlying effect is the so-called
The research, conducted by Wierikx at the Department of Industrial Engineering & Innovation Sciences, is based on more than 3,000 organizational assessments. The results reveal a consistent pattern: companies are relatively strong in setting circular ambitions, but face major
Many of the most exciting discoveries in science involve highly specialized knowledge and making connections between far-flung facts. Scientists must combine deep analysis with broad reasoning strategies.
Researchers at the University of Plymouth recently confirmed what board game fans and role-playing game (RPG) enthusiasts have known for decades: that tabletop games "enhance well-being, foster inclusion, and support learning, with strong evidence that games improve engagement."
Osaka Metropolitan University researchers have developed a light-driven technique that quickly amasses thousands of bacteria into a single spot, boosting detection speed and sensitivity. Their approach paves the way for earlier diagnosis of disease. The study is published in
It's getting crowded up there. Over the past few years, the advent of SpaceX's Starlink and other players in the mega-satellite constellation game are adding an exponential load of satellites and orbital debris to the low Earth orbit environment. But all that goes up, must
Three mathematicians have laid out proof that solves a long-standing problem in mathematics. Even the mathematician—an Abel prize winner—that first posed the problem didn't believe it would ever be solved. The solution provides insight into high-dimensional random structures
Marine microplastics affect algae's ability to grow and photosynthesize. Researchers have now calculated what impact this has on the greenhouse effect and the ocean's ability to absorb carbon dioxide.
Seismic waves traveling through Earth's interior often propagate at different speeds depending on their direction, a phenomenon known as seismic anisotropy. Such anisotropy is commonly detected beneath subduction zones, particularly near stagnant slabs in the mantle transition
With people increasingly adopting AI to help plan their vacations, hotels are working to make sure that you check them out—and check in.
Children from previous relationships growing up as siblings in a new family, couples adopting or fostering children: So-called patchwork families are a widespread way of life today. It is considered modern, but is in fact ancient, according to a recent analysis of human genetic
At least 16 people have died of heatstroke in southern India so far this summer, officials said Sunday, as a heat wave grips swathes of the country following official health warnings.
This teensy creature was discovered along a deep-sea mountain
When you look up at the sky on a sunny day, the sun might seem like a bright spot, unchanging in the sky. But the sun is a complex, dynamic celestial body, wrapped in electrical currents and magnetic fields that constantly move and tangle as it rotates. At times the sun's
Researchers found that adding bananas to berry smoothies can dramatically reduce the body’s ability to absorb healthy flavanols. The surprising discovery shows that even simple food combinations can change how much nutrition your body actually gets.
Scientists have cracked open the “black box” of feline cancer in a landmark study that genetically analyzed nearly 500 cat tumors from around the world. The research uncovered striking similarities between cancers in cats, dogs, and humans — including shared cancer-driving
Scientists have uncovered the oldest known hand-held wooden tools ever used by humans — and they’re an astonishing 430,000 years old. Buried for hundreds of thousands of years at an ancient lakeside site in Greece, the carefully carved wooden objects reveal that early humans
At the center of most large galaxies sits a supermassive black hole (SMBH). When these black holes are actively consuming material, they become incredibly luminous quasars. But some quasars appear wrapped in thick clouds of dust, making them hard to detect. In a new study,
Better algorithms, hardware and computing methods can lower AI’s power drain The post How to Tame AI’s Voracious Appetite for Energy appeared first on Nautilus .
For millions battling chronic nerve pain, even the softest touch can feel agonizing — but scientists may have uncovered a radically new way to stop it at the source. Researchers at Duke University found that damaged nerves can be revived by supplying them with healthy
By analyzing over 400,000 Reddit posts, researchers discovered that users of popular GLP-1 weight-loss drugs frequently discussed unexpected symptoms like menstrual irregularities, chills, and hot flashes. The findings suggest AI could turn social media into a powerful
A mysterious particle from deep space has scientists buzzing after the most energetic neutrino ever detected slammed through the Mediterranean Sea. Now, researchers think they may have identified the cosmic “culprits” behind it: blazars — supermassive black holes blasting jets
Scientists have directly watched angular momentum move through a crystal for the very first time — and discovered a bizarre twist along the way. Using ultra-powerful terahertz laser pulses, researchers triggered tiny atomic rotations inside a quantum material and found that the
Over the course of 13 expeditions and other efforts between mid-2025 and mid-2026, scientists found hundreds of previously undiscovered creatures living under the waves
A newly identified brain protein may play a major role in how the body ages. Researchers discovered that declining levels of Menin in the hypothalamus triggered inflammation, memory problems, bone loss, and other aging-related changes in mice. Restoring Menin reversed several
