Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria—the cell’s energy generators—can actively pull oxygen away from chloroplasts, the structures responsible for photosynthesis. This previously unknown interaction suggests mitochondria can effectively “drain” oxygen inside plant cells, altering photosynthesis and the production of reactive molecules that help plants respond to stress.View the full article

A prehistoric mass grave in Serbia reveals that more than 77 people—mostly women and children—were deliberately killed in a brutal act of violence about 2,800 years ago. Genetic evidence suggests the victims came from different communities, indicating the massacre may have been a calculated message during fierce territorial struggles in Iron Age Europe.View the full article

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of gravity, which explains the behavior of stars, planets, and the structure of the universe. Researchers at TU Wien have now taken a new step toward that goal by rethinking one of relativity’s core ideas: the paths particles follow through curved spacetime, known as geodesics. By creating a quantum version of these paths—called the q-desic equation—the team showed that particles moving through a “quantum” spacetime may deviate slightly from the paths predicted by classical relativity.View the full article

Engineers have discovered an unexpected link between two very different realms of physics: the behavior of electrons in graphene and magnetic waves in specially engineered materials. By designing a thin magnetic film with a hexagonal pattern of holes—similar to graphene’s structure—the researchers showed that magnetic “spin waves” can follow the same mathematical rules as graphene’s famously unusual electrons. The surprising overlap reveals a deeper connection between electronic and magnetic systems and gives scientists a powerful new way to study complex magnetic materials.View the full article

A Yale study found that lowering parent stress can help protect young children from obesity. When parents practiced mindfulness and stress-management skills, their kids showed healthier eating patterns and avoided the weight gain seen in families that only focused on diet and exercise.View the full article

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint “Lyman-alpha” light emitted by energized hydrogen, scientists used an advanced technique called line intensity mapping to capture not just the brightest galaxies but also the vast cosmic structures surrounding them.View the full article

A new brain-imaging study has revealed how ketamine produces its fast antidepressant effects in people with treatment-resistant depression. Researchers tracked changes in a critical brain receptor that helps neurons communicate and found that ketamine reshapes its activity in specific brain regions tied to mood and reward. These shifts strongly matched improvements in patients’ symptoms. The findings could help scientists develop better ways to predict who will benefit from ketamine therapy.View the full article

While exploring ancient seabeds in Morocco, scientists discovered strange wrinkle-like textures in deep-water sediments that shouldn’t have been there. These structures are usually made by sunlight-loving microbial mats in shallow waters. But the rocks formed far below the reach of light, suggesting a different explanation. Evidence points to chemosynthetic microbes—organisms powered by chemical reactions—creating the mats in the dark depths of an ancient ocean.View the full article

A massive UK study of more than 165,000 dementia patients has uncovered troubling new evidence about risperidone, a commonly used drug for severe agitation. Researchers found the antipsychotic increases stroke risk in dementia patients across the board—including those with no prior heart disease or stroke—challenging the long-held belief that some patients might be safer candidates than others. Because risperidone is the only drug of its type licensed for dementia, doctors often use it as a last resort when distressing symptoms become unmanageable.View the full article

A growing trend called “fibermaxxing” is putting dietary fiber in the spotlight—and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough fiber may even lower the risk of conditions like obesity, diabetes, and certain cancers.View the full article

Satellites are giving scientists a powerful new way to watch over the world’s bridges. Using radar imaging, researchers can detect millimeter-scale movements that may signal early structural problems long before inspectors notice them. The study found many bridges—especially in North America—are aging and increasingly vulnerable, but satellite monitoring could sharply reduce the number classified as high-risk. The approach could be especially valuable in regions where traditional monitoring barely exists.View the full article

Scientists are exploring a new way to harness the medical promise of psychedelic compounds without the mind-bending side effects. Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that still target key serotonin pathways linked to depression and other brain disorders but appear to cause far fewer psychedelic-like effects.View the full article

Scientists have uncovered a surprising new role for little-known brain cells called tanycytes that may influence the development of Alzheimer’s disease. These specialized cells appear to help remove toxic tau protein from the brain by transporting it from the cerebrospinal fluid into the bloodstream. When tanycytes become damaged or dysfunctional, tau can accumulate in the brain, a hallmark of Alzheimer’s.View the full article

Scientists have revealed how the body’s microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of “cool” works at the molecular level—and could inspire new treatments for pain and eye disorders.View the full article

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number of protons equals the number of neutrons. For decades, these strange regions—where atomic nuclei abandon their usual orderly structure and become strongly deformed—were thought to exist only in highly neutron-rich isotopes far from stability. But experiments on molybdenum isotopes revealed that molybdenum-84 behaves dramatically differently from its close neighbor molybdenum-86, even though they differ by just two neutrons.View the full article

Asteroids with tiny moons may be quietly trading material across space. Images from NASA’s DART mission revealed faint streaks on the moon Dimorphos—evidence of slow “cosmic snowballs” drifting from its parent asteroid, Didymos. The discovery provides the first direct visual proof that sunlight can spin asteroids fast enough to shed debris that lands on nearby companions. It also shows that near-Earth asteroids are much more active and constantly reshaped than scientists once believed.View the full article

Scrolling on your phone while sitting on the toilet might be doing more harm than you think. A new study found that people who use smartphones during bathroom visits had a 46% higher risk of hemorrhoids compared to those who don’t. Researchers discovered that phone users tend to spend significantly longer on the toilet, often getting distracted by news or social media, which may increase pressure on anal tissues.View the full article

A sweeping new study from Northwestern University reveals that scientific fraud is no longer just the work of a few rogue researchers—it has evolved into a global, organized enterprise. By analyzing massive datasets of publications, retractions, and editorial records, researchers uncovered networks involving “paper mills,” brokers, and compromised journals that systematically produce and sell fake research, authorship slots, and citations.View the full article

Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism. The study suggests that nitric oxide, a tiny signaling molecule normally involved in fine-tuning communication between brain cells, can sometimes trigger a cascade of changes inside neurons. When nitric oxide activity rises, it can alter a protective protein called TSC2, weakening an important cellular brake and allowing the mTOR pathway, which controls growth and protein production, to become overactive.View the full article

New research suggests seabird guano helped transform the Chincha Kingdom into one of the most prosperous societies in ancient Peru. Chemical clues in centuries-old maize show farmers fertilized their crops with guano gathered from nearby islands, dramatically boosting yields in the desert landscape. The resulting agricultural surplus fueled trade, population growth, and regional influence.View the full article

Solid-state batteries could be safer and more energy-dense than today’s lithium-ion technology, but finding materials that allow ions to move quickly through solid electrolytes has been difficult. Researchers developed a machine learning pipeline that predicts Raman spectra and identifies a distinctive low-frequency signal linked to liquid-like ion motion inside crystals. This signal appears when rapid ion movement temporarily disrupts a crystal’s symmetry. The approach could dramatically speed up the discovery of superionic materials for advanced batteries.View the full article

Scientists studying 1,300 golden retrievers have uncovered genetic clues explaining why some dogs are more anxious, energetic, or aggressive than others. Remarkably, several of the same genes linked to canine behavior are also tied to human traits like anxiety, depression, and intelligence. The discovery suggests dogs and humans share biological roots for emotions and behavior. Understanding these links could help owners better interpret their pets’ reactions and even improve training and veterinary care.View the full article

Mayo Clinic researchers have identified a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease. The mutation disrupts the liver’s ability to process fat, leading to inflammation, scarring, and potentially cirrhosis. The discovery began with a father and daughter who had the disease without typical risk factors. Large-scale genomic data suggests similar rare variants may quietly contribute to the disease in many more people.View the full article

Researchers in Sweden have engineered a cell-free cartilage scaffold that can guide the body to rebuild damaged bone. By removing the cells but preserving the structure and natural growth signals, the material acts as a blueprint for the body’s own repair process. In animal studies, it helped regenerate bone without triggering strong immune reactions. The team now plans to scale up production and begin testing the approach in humans.View the full article

A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, shutting down this protein stopped the damage before it could take hold. The finding could pave the way for treatments that protect vision before symptoms ever begin.View the full article
