New treatment cuts bad cholesterol by nearly 50% without statins11:20 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 potential10:16 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 science10:16 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 stones10:16 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 ocean10:16 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 eating10:16 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 shelves10:16 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 protein30.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 relief30.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 questions30.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… A photon was teleported across 270 meters in stunning quantum breakthrough30.dubna Scientists have pulled off a first: teleporting a photon’s state between two separate quantum dots. This was done over a 270-meter open-air link, proving quantum information can travel between independent devices. The achievement marks a key step toward building quantum networks for ultra-secure communication. It also sets the stage for more advanced systems like quantum relays. Earth is splitting open beneath the Pacific Northwest, scientists say30.dubna For the first time, scientists have watched a subduction zone literally fall apart beneath the ocean floor. Using advanced seismic imaging, they found the Juan de Fuca plate splitting into fragments as it sinks beneath North America. Rather than collapsing all at once, the plate is tearing piece by piece, like a train slowly derailing. The finding helps explain ancient plate fragments and could r… A hidden map in your nose could explain how smell works30.dubna Scientists have finally cracked one of the biggest mysteries in the senses: how smell is organized. By mapping millions of neurons in mice, researchers discovered that smell receptors in the nose aren’t random at all—they’re arranged in neat, overlapping stripes based on receptor type, forming a hidden structure scientists never knew existed. Even more striking, this layout mirrors how smell info… First-ever 3D view shows how killer T cells destroy cancer30.dubna The body’s “killer” T cells don’t just attack—they strike with astonishing precision, forming a tiny, highly organized contact zone that lets them destroy dangerous cells without harming their neighbors. Now, scientists have captured this process in unprecedented detail, revealing a hidden world of molecular choreography. Bronze Age mines discovered in Spain may explain Scandinavian metal mystery30.dubna Archaeologists have uncovered six previously unknown Bronze Age mines in southwestern Spain, offering a striking new clue about where the metal in ancient Scandinavian artifacts may have come from. Found near Cabeza del Buey, the sites include everything from small extraction zones to larger mining operations—one even packed with around 80 stone axes used to crush ore. These mines contain copper,… |
