Scientists discover the body’s hidden “off switch” for inflammation16:28 A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules reduced pain faster and lowered harmful inflammatory cells. The discovery could pave the way for safer treatments for arthritis, heart disease, and oth… Atom-sized gates could transform DNA sequencing and neuromorphic computing16:28 Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough opens new possibilities for single-molecule sensing, neuromorphic computing, and studying how matter behaves in spaces barely larger than atoms. Scientists discover gene that could save bananas from deadly Panama disease16:28 A major breakthrough could help save the world’s bananas from a devastating disease. Scientists have discovered the exact genetic region in a wild banana that provides resistance to Fusarium wilt Subtropical Race 4 — a destructive strain that threatens Cavendish bananas worldwide. While this wild banana isn’t edible, the discovery gives breeders a powerful genetic roadmap to develop future banana… Scientists finally explain why chronic constipation treatments often fail15:16 A newly discovered bacterial duo may be the hidden cause of chronic constipation. The two microbes break down the colon’s protective mucus layer, leaving stool dry and hard — a problem traditional laxatives don’t fix. Parkinson’s patients, who often struggle with constipation years before tremors appear, have higher levels of these bacteria. Blocking the bacteria’s mucus-destroying enzyme prevent… Brain development may continue into your 30s, new research shows15:16 That viral claim that your frontal lobe “isn’t fully developed until 25” turns out to be more myth than milestone. Early brain scans showed that gray matter changes dramatically through the teen years, and because studies stopped around age 20, scientists estimated development might wrap up in the mid-20s. But newer, massive brain-imaging research paints a different picture: key wiring and networ… Ancient DNA solves 5,500 year old burial mystery in Sweden15:16 Ancient DNA from a Stone Age burial site in Sweden shows that families 5,500 years ago were more complex than expected. Many individuals buried together were not immediate family, but second- or third-degree relatives. One grave held a young woman alongside two children who were siblings—yet she wasn’t their mother. The discoveries hint at tight-knit communities where extended kin mattered deeply. The nearsightedness explosion may be fueled by dim indoor light, not just screens15:16 Myopia is skyrocketing around the world, often blamed on endless screen time — but new research suggests the real culprit may be something more subtle. Scientists at SUNY College of Optometry propose that it’s not just devices, but the combination of prolonged close-up focus and dim indoor lighting that may quietly strain the eyes. When we concentrate on nearby objects in low light, our pupils co… New map reveals where lethal scorpions are most likely to strike7:21 Scientists have developed a powerful new way to forecast where some of the world’s most dangerous scorpions are likely to be found. By combining fieldwork in Africa with advanced computer modeling, the team discovered that soil type is the strongest factor shaping where many lethal species live, while temperature patterns also play a key role. AI breakthrough could replace rare earth magnets in electric vehicles7:21 Scientists at the University of New Hampshire have unleashed artificial intelligence to dramatically speed up the hunt for next-generation magnetic materials. By building a massive, searchable database of 67,573 magnetic compounds — including 25 newly recognized materials that stay magnetic even at high temperatures — the team is opening the door to cheaper, more sustainable technologies. New sodium ion battery stores twice the energy and desalinates seawater7:21 A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among th… Ancient drought may have wiped out the real-life hobbits 61,000 years ago7:21 A massive, centuries-long drought may have driven the extinction of the “hobbits” of Flores. Climate records preserved in cave formations show rainfall plummeted just as the small human species disappeared. At the same time, pygmy elephants they depended on declined sharply as rivers dried up. With food and water vanishing, the hobbits may have been pushed out—and into their final chapter. Sugary drinks linked to rising anxiety in teens18.února Sugary drinks may be linked to more than just physical health problems in teens. A new review of multiple studies found a consistent association between high consumption of beverages like soda, energy drinks, sweetened juices, and flavored milks and increased anxiety symptoms in adolescents. Intermittent fasting fails to beat standard dieting for weight loss18.února Intermittent fasting has become one of the most talked-about weight loss trends in recent years, promising dramatic results with simple changes to when you eat. But a major Cochrane review suggests the reality may be far less exciting. After analyzing 22 clinical trials involving nearly 2,000 adults, researchers found that intermittent fasting did not produce significantly more weight loss than s… A spinning gyroscope could finally unlock ocean wave energy18.února Ocean waves are a vast and steady source of renewable energy, but capturing their power efficiently has long frustrated engineers. A researcher at The University of Osaka has now explored a bold new approach: a gyroscopic wave energy converter that uses a spinning flywheel inside a floating structure to turn wave motion into electricity. By harnessing gyroscopic precession—the subtle wobble of a … This reengineered HPV vaccine trains T cells to hunt down cancer18.února Northwestern researchers have shown that when it comes to cancer vaccines, arrangement can be just as important as ingredients. By repositioning a small fragment of an HPV protein on a DNA-based nanovaccine, the team dramatically strengthened the immune system’s attack on HPV-driven tumors. One specific design slowed tumor growth, extended survival in animal models, and unleashed far more cancer-… |
