When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate. Pinpointing the stressors that help trigger or accelerate replicative senescence has
Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as "triple-double" radio galaxies (TDRGs). Located nearly 7.5 billion light-years away, this unique
In a study published in The Anatomical Record, researchers have identified a new species of large-bodied gorgonopsian from the middle Permian. The discovery pushed back the known origins of when these apex predators began evolving large bodies and their unique later skull
Volcanoes are both captivating and disastrous. Most are likely familiar with the common short-term dangers associated with them: explosive forces, lava, and even atmospheric particles disrupting air traffic. But researchers also explore longer-term impacts of eruptions, as
Green roofs and green walls are no longer niche design features but proven, scalable nature-based solutions that can significantly enhance biodiversity, climate resilience, energy efficiency and human well-being in European cities. This is a central finding of a new knowledge
The rainforests of northern Australia are home to extraordinary ant colonies. Instead of dwelling in underground burrows, these ants inhabit canopies of trees, dozens of meters above the ground, inside hollow spheres they construct from tree leaves. During the building process,
The people who toiled night and day to put astronauts on the moon during Apollo are thrilled that NASA is finally going back. They just wish these Artemis moonshots had happened sooner while more of Apollo's workforce was still alive.
Infections of the BA.3.2 variant of the COVID-causing coronavirus are still at very low levels, but experts are concerned it may be resistant to immunity from vaccines or prior infection

Curtin University research has found farmers making small changes to how they give water to cattle in semi-arid regions could halt the spread of one of Australia's most damaging invasive species—all without disrupting farming operations. Published in Global Ecology and
Certain smaller sauropods could stand on their hind legs with surprising ease, giving them access to higher food and a defensive edge. Computer simulations show their bones handled stress better than those of their larger relatives. However, as they grew, the sheer weight made
A major analysis of nearly 10,000 patients shows that simple, non-drug treatments like knee braces, hydrotherapy, and exercise can significantly ease knee osteoarthritis symptoms. These approaches not only reduce pain and improve mobility, but also avoid the risks tied to
Astronomers have spotted a bizarre cosmic explosion that refuses to play by the rules—and it’s leaving scientists scrambling for answers. GRB 250702B, detected by NASA’s James Webb Space Telescope and a global network of observatories, lasted an astonishing seven hours—far
A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of light-years away. This could explain why some galaxies near early quasars appear
Douglas Adams told us the answer to life, the universe and everything is 42. If only cosmology were so straightforward. Astronomers have been arguing for years about a number every bit as fundamental, and they still can't agree on it.
Experiments by University of Leeds researchers, published in Earth's Future, have shown that thawing of permafrost makes it between 25 and 100 times more permeable, allowing more climate change forcing gases to escape.
Snakes that gain poisons from eating toads seem to know when they’re toxic by keeping track of what they last ate
Researchers have identified genetic material from a vast range of organisms contaminating the shroud, said to have wrapped Jesus's body, further complicating the question of the cloth's true origin

From color-changing skin to jet-propelled motion, squid and cuttlefish have long fascinated scientists. To understand the origins of their unique characteristics, many attempts have been made to define their evolutionary history. However, the limited fossil record and
The UN Convention on the Conservation of Migratory Species of Wild Animals (CMS) on Sunday approved the listing of 40 new species for international protection, including the snowy owl featured in the Harry Potter saga.
To survive in the human bloodstream, the African trypanosome parasite wears a "cloak" made of proteins known as a variant surface glycoprotein (VSG). The study, published in Nature Microbiology, identifies the protein that allows the parasite to fine-tune this "cloak."
Some Arctic regions regain their "greenness" within a decade of a sudden permafrost collapse, while others can take a century or more to recover, researchers report in a new study. The difference is directly related to each site's gross primary productivity, a measure of its
A humpback whale struggling in shallow waters off Germany's northern Baltic Sea coast has become stranded for a third time, experts said on Sunday, just hours after the animal had freed itself from a sandbank.
Desperate to help his sick dog, one Australian man went down the ultimate ChatGPT research hole, using artificial intelligence to design a personalized experimental treatment and finding top scientists to administer it.
NASA's Apollo moonshots are a tough act to follow, even after all this time.
A large U.S. study reveals that more than a quarter of people with hard-to-treat high blood pressure may have an overlooked hormone problem. Elevated cortisol—often linked to stress—was found in 27% of these patients, far higher than expected. This hidden condition could
A powerful cholesterol-lowering drug may be changing the rules of heart disease prevention. Researchers found that evolocumab, typically used for people who already have cardiovascular disease, can significantly cut the risk of first-time heart attacks and strokes in high-risk
Experiments on different kinds of milk have revealed that many plant-based milks are non-Newtonian fluids
An accounting of all the water that should have been and gone on Mars’s surface has come up with a discrepancy that shows just how little we understand the Red Planet’s hydrological history
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
