This 275-million-year-old animal had a twisted jaw like nothing alive today

16:40
Deep in a dried-up riverbed in Brazil, scientists uncovered a bizarre prehistoric mystery—twisted jawbones from a strange, long-lost animal unlike anything seen before. Dating back 275 million years, this creature, named Tanyka amnicola, belonged to an ancient lineage that should have already faded away, making it a kind of “living fossil” of its time.

This “Pink Floyd” spider hunts prey 6x its size and lives in walls

16:40
Scientists have uncovered a tiny wall-dwelling spider named Pikelinia floydmuraria, inspired by Pink Floyd. Despite its size, it’s a fierce predator that hunts ants much larger than itself and helps reduce common urban pests like mosquitoes and flies. Its clever strategy of building webs near lights makes it especially effective. The discovery also raises new questions about its mysterious link t…

You don’t need intense workouts to build muscle, new study reveals

16:40
Building muscle doesn’t have to mean exhausting workouts or soreness. Researchers found that slow, controlled “lowering” movements can boost strength more efficiently while requiring less effort. Even five minutes a day of simple exercises like chair squats or wall push-ups can make a real difference. It’s a smarter, easier way to get stronger—no gym required.

Oxford physicists achieve first-ever “quadsqueezing” breakthrough in quantum physics

16:40
Scientists have created a powerful new way to control quantum systems, achieving the first-ever demonstration of quadsqueezing—an elusive fourth-order quantum effect. By combining simple forces in a clever way, they made previously hidden quantum behaviors visible and usable, opening new frontiers for quantum technology.

This new aluminum could replace rare metals and cut costs dramatically

16:40
A team at King’s College London has created a powerful new aluminum compound capable of doing the work of expensive rare metals. Its unique triangular structure gives it remarkable stability and reactivity, allowing it to drive chemical reactions in ways never seen before. The discovery could lead to greener and far more affordable industrial processes. It may even enable the creation of entirely…

New treatment cuts bad cholesterol by nearly 50% without statins

11:20
A new breakthrough could change how high cholesterol is treated, offering a powerful alternative to traditional drugs. Researchers have developed tiny DNA-based molecules that shut down PCSK9—a key protein that keeps “bad” LDL cholesterol circulating in the blood. By blocking this protein, cells can absorb more cholesterol instead of letting it build up in arteries, dramatically lowering levels l…

Don’t toss cannabis leaves: Scientists found rare compounds with medical potential

10:16
Scientists have uncovered a surprising new layer of complexity in Cannabis, identifying dozens of previously unknown compounds—including the first-ever evidence of rare molecules called flavoalkaloids in its leaves. These compounds, prized for their potential health benefits, were hidden among a rich mix of plant chemicals that vary dramatically even between just a few strains.

Surprising obesity discovery rewrites decades of fat metabolism science

10:16
A key protein involved in fat metabolism has been found to do more than scientists once thought. Instead of just releasing fat, it helps maintain healthy fat tissue and balance in the body. When it’s missing or disrupted, the results can be surprisingly harmful. This finding reshapes how researchers think about obesity and metabolic disease.

Why drinking more water didn’t prevent kidney stones

10:16
Kidney stones are notoriously painful—and frustratingly common, with many people facing repeat episodes. A massive new study tested whether a high-tech hydration program—complete with smart water bottles, reminders, coaching, and even financial incentives—could help people drink enough water to stop stones from coming back.

Scientists finally explain how the Twelve Apostles rose from the ocean

10:16
Australia’s famous Twelve Apostles didn’t just erode into existence—they were slowly pushed up from the ocean floor by powerful tectonic forces over millions of years, new research reveals. Scientists discovered that these towering limestone stacks act like a natural time capsule, preserving clues about ancient climates, sea levels, and even life from up to 14 million years ago.

Your gut takes a “double hit” from stress and late-night eating

10:16
Chronic stress is already tough on your gut—but new research suggests late-night eating could make things even worse. Scientists analyzing thousands of people found that those under high stress who also ate a large portion of their calories after 9 p.m. were far more likely to suffer from constipation and diarrhea. The combination appears to hit the gut twice, not only disrupting digestion but al…

Hidden ocean heat is creeping toward Antarctica’s fragile ice shelves

10:16
Deep beneath the Southern Ocean, a quiet but alarming shift is underway: warm water is creeping closer to Antarctica, and scientists are now seeing it clearly for the first time. By combining decades of ship data with robotic float measurements and machine learning, researchers uncovered that a massive pool of heat—circumpolar deep water—has expanded and edged toward the continent over the past 2…

Scientists restore memory by blocking a single Alzheimer’s protein

30.dubna
Researchers have identified a new potential weapon against Alzheimer’s: blocking a protein called PTP1B. In mice, this approach boosted memory and helped brain immune cells clear harmful plaque buildup. Since PTP1B is also linked to diabetes and obesity—both risk factors for Alzheimer’s—it could offer a broader treatment strategy.

Scientists reveal the best exercise for knee arthritis pain relief

30.dubna
A major review of 217 trials shows that aerobic exercise is the most effective option for managing knee osteoarthritis. Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement. While alternatives like strength training and mind-body exercises help, they are best used alongside aerobic workouts. The findings also confirm that exercis…

This AI knew the answers but didn’t understand the questions

30.dubna
For decades, psychologists have debated whether the human mind can be explained by one unified theory or must be broken into separate parts like memory and attention. A recent AI model called Centaur seemed to offer a breakthrough, claiming it could mimic human thinking across 160 different cognitive tasks. But new research is challenging that bold claim, suggesting the model isn’t truly “thinkin…
