A quantum mystery that stumped scientists for decades is solved17:35 A long-standing physics mystery has been solved with the discovery of emergent photon-like behavior inside a strange quantum material. The finding confirms a true 3D quantum spin liquid and unlocks a new way to study deeply entangled matter. He ate a hamburger and died hours later. Doctors found a shocking cause15:48 A rare tick-borne allergy linked to red meat has now been confirmed as deadly for the first time. A healthy New Jersey man collapsed and died hours after eating beef, with later testing revealing a severe allergic reaction tied to alpha-gal, a sugar spread by Lone Star tick bites. Symptoms often appear hours later, making the condition easy to miss. Researchers warn that growing tick populations … New study reveals how kimchi boosts the immune system14:37 Kimchi may do far more than add flavor to meals—it could help fine-tune the human immune system. A clinical study using advanced single-cell genetic analysis found that regular kimchi consumption strengthens immune defenses while preventing harmful overreactions. Researchers observed improved activity in key immune cells, with effects varying depending on fermentation methods. A new test could reveal Alzheimer’s before symptoms appear12:50 Scientists at Northern Arizona University are developing a promising new way to detect Alzheimer’s disease earlier than ever before—by tracking how the brain uses sugar. Using tiny particles in the blood called microvesicles, researchers may soon be able to gather brain-specific information without invasive procedures. If successful, this approach could transform Alzheimer’s diagnosis, monitoring… A hidden star found where dust shouldn’t exist12:50 A mysterious cloud of ultra-hot dust around Kappa Tucanae A may finally have an explanation: a hidden companion star. The star’s extreme orbit carries it straight through the dust zone, strongly suggesting it plays a key role in keeping the dust alive. This finding could help astronomers untangle one of the biggest challenges in imaging Earth-like exoplanets. It also opens the door to discovering… Scientists reveal why some brains stop growing too soon12:50 Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small brains. Changes in actin disrupted the orientation of early brain cell divisions, causing crucial progenitor cells to disappear too soon. This reduced the brain’s ability to grow normally. The work offers a clear cellular explanation for microcephaly linked to Baraitser-Winte… A loud minority makes the Internet look far more toxic than it is12:50 People think online platforms are overflowing with toxic and misleading content, but the reality is far calmer. A small group of highly active users creates most of the harm, while the majority remain relatively civil. Still, many Americans assume the worst about each other because of this imbalance. Correcting that belief can noticeably improve how people feel about society. This 8,000-year-old art shows math before numbers existed7:45 Over 8,000 years ago, early farming communities in northern Mesopotamia were already thinking mathematically—long before numbers were written down. By closely studying Halafian pottery, researchers uncovered floral and plant designs arranged with precise symmetry and numerical patterns, revealing a surprisingly advanced sense of geometry. Scientists reveal a 1.5-million-year-old human face7:45 Scientists have digitally reconstructed the face of a 1.5-million-year-old Homo erectus fossil from Ethiopia, uncovering an unexpectedly primitive appearance. While its braincase fits with classic Homo erectus, the face and teeth resemble much older human ancestors. This discovery challenges long-held ideas about where and how Homo erectus evolved. It also hints at a complex web of migrations and… Ramanujan’s 100-year-old pi formula is still revealing the Universe5:30 Ramanujan’s elegant formulas for calculating pi, developed more than a century ago, have unexpectedly resurfaced at the heart of modern physics. Researchers at IISc discovered that the same mathematical structures behind these formulas also describe real-world phenomena like turbulence, percolation, and even black holes. What once seemed like pure mathematics now appears deeply intertwined with t… A simple turn reveals a 1,500-year-old secret on Roman glass16.prosince A museum visit sparked a revelation when a Roman glass cup was turned around and its overlooked markings came into focus. These symbols, once dismissed as decoration, appear to be workshop identifiers used by teams of skilled artisans. The findings challenge centuries of assumptions about how Roman glass was made. They also restore identity and agency to the anonymous makers behind these stunning… Living cells may generate electricity from motion16.prosince Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These signals could help drive ion transport and explain key biological functions. The work may also guide the design of intelligent, bio-inspired materials. Colon cancer is surging in younger adults and doctors are alarmed16.prosince Cases of colorectal cancer in younger adults are climbing worldwide, driven by lifestyle changes and inherited genetic risks. Diet, obesity, and lack of early screening are playing a major role in this shift. New genetic tests offer hope for earlier detection, but access and awareness lag behind. Health experts say urgent action is needed to reverse the trend. A new way to prevent gum disease without wiping out good bacteria16.prosince Scientists are uncovering a surprising way to influence bacteria—not by killing them, but by changing how they communicate. Researchers studying oral bacteria found that disrupting chemical signals used in bacterial “conversations” can shift dental plaque toward healthier, less harmful communities. The discovery could open the door to new treatments that prevent disease by maintaining a balanced … Physicists found a way to see heat in empty space16.prosince Physicists have found a clever way to detect the elusive Unruh effect without extreme accelerations. By using atoms that emit light cooperatively between mirrors, acceleration subtly shifts when a powerful light burst appears. That early flash acts like a timestamped signature of the effect. The method could make once-theoretical physics experimentally reachable. |
