A newly detected super-Earth just 20 light-years away is giving scientists one of the most promising chances yet to search for life beyond our solar system. The discovery of the exoplanet orbiting in the habitable zone of its star was made possible by advanced spectrographs designed at Penn State and by decades of observations from telescopes around the world.

Researchers engineered “gyromorphs,” a new type of metamaterial that combines liquid-like randomness with large-scale structural patterns to block light from every direction. This innovation solves longstanding limitations in quasicrystal-based designs and could accelerate advances in photonic computing. Read more ›

Bumble bees battling invasive Argentine ants may win individual fights but ultimately lose valuable foraging time, putting pressure on colonies already strained by habitat loss, disease, and pesticides. New research shows bees often avoid ant-occupied feeders, and while their size helps them win one-on-one clashes, these encounters trigger prolonged aggression that keeps them from collecting food.

Researchers have uncovered surprising evidence that anxiety may be controlled not by neurons but by two dueling groups of immune cells inside the brain. These microglia act like biological pedals—one pushing anxiety forward and the other holding it back. Read more ›

Scientists studying aging found that sensory inputs like touch and smell can cancel out the lifespan-boosting effects of dietary restriction by suppressing the key longevity gene fmo-2. When overactivated, the gene makes worms oddly indifferent to danger and food, suggesting trade-offs between lifespan and behavior. The work highlights how deeply intertwined the brain, metabolism, and environment are. These pathways may eventually be targeted to extend life without extreme dieting. Read more ›

Smoking, vaping, or using both products significantly increases the likelihood of developing prediabetes and diabetes, and the risk is even higher among Hispanic, Black, and low-income groups. Researchers found that vaping alone raises prediabetes risk, while combining cigarettes and e-cigarettes drives those odds up dramatically. Read more ›

Footprints preserved on ancient dunes show Neanderthals actively navigating, hunting, and living along Portugal’s coastline. Their behavior and diet suggest a far more adaptable and socially complex population than once assumed. Read more ›

Scientists have developed a new way to build rare-earth crystals that boosts quantum coherence to tens of milliseconds. This leap could extend quantum communication distances from city blocks to entire continents. The method uses atom-by-atom construction for unprecedented material purity. Read more ›

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and chemistry of chondrite meteorites found on Earth. The findings also help explain why Earth and the other rocky planets remained near 1 AU rather than plunging inward. Read more ›

Arctic sea ice is disappearing fast, and scientists have turned to an unexpected cosmic clue—space dust—to uncover how ice has changed over tens of thousands of years. By tracking helium-3–bearing dust trapped (or blocked) by ancient ice, researchers built a remarkably detailed history of Arctic coverage stretching back 30,000 years. Their findings reveal powerful links between sea ice, nutrient availability, and the Arctic food web, offering hints about how future... Read more ›

Researchers discovered that living horsetails act like natural distillation towers, producing bizarre oxygen isotope signatures more extreme than anything previously recorded on Earth—sometimes resembling meteorite water. By tracing these isotopic shifts from the plant base to its tip, scientists unlocked a new way to decode ancient humidity and climate, using both modern plants and fossilized phytoliths that preserve isotopic clues for millions of years.

Researchers have designed a smart drug that hunts down and breaks a little-known RNA that cancer cells depend on. The drug recognizes a unique fold in the RNA and triggers the cell to destroy it. Tests showed that removing this RNA slows cancer growth. The approach could lead to new treatments that attack cancer at its most fundamental level. Read more ›

Scientists have discovered strange microscopic structures in the blood of people with Long COVID—clusters of tiny microclots tangled together with sticky immune webs known as neutrophil extracellular traps, or NETs. These combined structures show up far more often in Long COVID patients, where they appear larger, denser, and more stubborn than in healthy blood. Read more ›

Colchicine, a cheap and widely used gout drug, may help prevent heart attacks and strokes in people with cardiovascular disease. Trials involving nearly 23,000 patients show meaningful reductions in risk with low doses. Side effects were mostly mild and short-lived. Researchers say this overlooked drug could become an accessible prevention tool pending further study. Read more ›

Scientists have identified a new crocodile precursor that looked deceptively dinosaur-like and hunted with speed and precision. Named Tainrakuasuchus bellator, the armored “warrior” lived 240 million years ago and occupied a powerful niche in the Triassic food chain. Its fossils reveal deep evolutionary links between South America and Africa. The find sheds light on a vibrant ecosystem that existed just before dinosaurs emerged. Read more ›

Scientists have uncovered a new environmental culprit behind liver disease: tetrachloroethylene (PCE), a chemical used in dry cleaning and household products. The study found that people with PCE exposure were three times more likely to develop severe liver scarring, even when traditional risk factors like alcohol or obesity were absent. The chemical is widespread in air, water, and consumer goods, making it a stealthy threat to public health. Read more ›

New research from the Technical University of Munich and Harvard Medical School reveals that popular GLP-1-based drugs, semaglutide (Ozempic) and tirzepatide (Mounjaro), not only promote weight loss but also significantly reduce the risk of heart attacks and strokes in patients with type 2 diabetes. Using real-world insurance data, the study found up to an 18% reduction in major cardiovascular events, confirming powerful heart-protective effects that appear to extend beyond weight... Read more ›

Boron arsenide has dethroned diamond as the best heat conductor, thanks to refined crystal purity and improved synthesis methods. This discovery could transform next-generation electronics by combining record-breaking thermal conductivity with strong semiconductor properties. Read more ›

Over 500 million years ago, the Cambrian Period sparked an explosion of skeletal creativity. Salterella, a peculiar fossil, defied conventions by combining two different mineral-building methods. After decades of confusion, scientists have linked it to the cnidarian family. The find deepens our understanding of how animals first learned to build their own skeletons. Read more ›

Scientists in Seoul have uncovered 15 gut bacterial species linked to coronary artery disease, showing that microbes can influence heart health far beyond digestion. Their findings reveal how shifts in gut microbial function — including inflammation, loss of protective species, and overactive metabolic pathways — may drive disease progression. Intriguingly, even “good” bacteria like Faecalibacterium prausnitzii and Akkermansia muciniphila can become harmful under certain conditions. Read more ›
