Over 40% of fatal crash victims had THC levels far above legal limits, showing cannabis use before driving remains widespread. The rate didn’t drop after legalization, suggesting policy changes haven’t altered risky habits. Experts warn that the lack of public awareness around marijuana’s dangers behind the wheel is putting lives at risk. Source link

MIT scientists uncovered direct evidence of unconventional superconductivity in magic-angle graphene by observing a distinctive V-shaped energy gap. The discovery hints that electron pairing in this material may arise from strong electronic interactions instead of lattice vibrations. Source link

In a remarkable blend of science and tradition, researchers have revived an old Balkan and Turkish yogurt-making technique that uses ants as natural fermenters. The ants’ bacteria, acids, and enzymes transform milk into a rich, tangy yogurt while showcasing the diversity and complexity lost in modern, industrialized yogurt strains. Source link

A team at the University of Stuttgart has engineered a compact short-pulse laser that achieves up to 80% efficiency—far surpassing current models. Their new multipass design reuses light within a small crystal, combining power and precision in a palm-sized system. It opens the door to portable, cost-effective lasers for medicine, analytics, and quantum science. Source link

Despite massive technological and industrial changes, American cities have stayed remarkably coherent in how their economies fit together. This hidden order governs how cities diversify, grow, and reinvent themselves without losing their economic identity. Source link

Researchers have discovered quantum oscillations inside an insulating material, overturning long-held assumptions. Their work at the National Magnetic Field Laboratory suggests that the effect originates in the material’s bulk rather than its surface. The finding points toward a “new duality” in materials science—where compounds may behave as both metals and insulators—offering a fascinating puzzle for future research. Source link

Researchers confirmed that Rapa Nui’s moai statues could “walk” upright using a rocking motion, aided by rope and just a few people. Experiments with replicas and 3D models revealed design features like a forward lean and curved bases that made movement possible. Concave roads across the island further supported this transport method. The findings celebrate the innovation and intelligence of the ancient islanders. Source link

Stanford scientists found that strontium titanate improves its performance when frozen to near absolute zero, showing extraordinary optical and mechanical behavior. Its nonlinear and piezoelectric properties make it ideal for cryogenic quantum technologies. Once overlooked, this cheap, accessible material now promises to advance lasers, computing, and space exploration alike. Source link

Men’s heavy drinking is fueling a hidden crisis affecting millions of women and children worldwide. The harms, from violence to financial instability, are especially severe where gender inequality is high. Experts warn that alcohol policies must include gender-responsive strategies to protect vulnerable families. They call for reforms combining regulation, prevention, and community action. Source link

NASA’s Cassini mission has revealed surprising heat flow at Enceladus’ north pole, showing the moon releases energy from both ends. This balance of heat could allow its subsurface ocean to remain liquid for billions of years, supporting conditions for life. The study also refined estimates of ice thickness, giving scientists a clearer picture of where to search next. Source link

Around 9,000 years ago, East Antarctica went through a dramatic meltdown that was anything but isolated. Scientists have discovered that warm deep ocean water surged beneath the region’s floating ice shelves, causing them to collapse and unleashing a domino effect of ice loss across the continent. This process created a “cascading positive feedback,” where melting in one area sped up melting elsewhere through interconnected ocean currents. Source link

Archaeologists in Saudi Arabia discovered over 170 ancient rock engravings that may be among the earliest monumental artworks in the region. Created between 12,800 and 11,400 years ago, the massive figures were carved when water and life returned to the desert. The art likely marked territories and migration routes, revealing social and symbolic sophistication. Artifacts found nearby show early Arabian peoples connected to distant Neolithic communities.

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest evidence yet for an evolving cosmic force. Source link

In Death Valley’s relentless heat, Tidestromia oblongifolia doesn’t just survive—it thrives. Michigan State University scientists discovered that the plant can quickly adjust its photosynthetic machinery to endure extreme temperatures that would halt most species. Its cells reorganize, its genes switch on protective functions, and it even reshapes its chloroplasts to keep producing energy. The findings could guide the creation of crops capable of withstanding future heat waves. Source link

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at different points, researchers can now watch damage flare up, track repair proteins rushing to the site, and see the moment the DNA is restored. Built from a natural protein that binds gently and briefly to damaged DNA, the sensor offers a true-to-life view of the cell’s internal emergency response. Source link

A University of Toronto study found that nearly one in four adults aged 60+ who reported poor well-being were able to regain optimal wellness within three years. The research highlights that physical activity, healthy weight, good sleep, and emotional and social support play crucial roles in recovery. Those with strong psychological wellness at the start were five times more likely to bounce back. Source link

Researchers discovered that raising the protein Sox9 can help the brain’s astrocytes clear out toxic plaque buildup linked to Alzheimer’s. In mouse models that already showed memory problems, activating these cells improved cognitive performance. The treatment also reduced plaque levels over time. The work points toward a natural, cell-based way to slow Alzheimer’s decline. Source link

Astronomers have discovered phosphine gas in the atmosphere of an ancient brown dwarf, Wolf 1130C, using the James Webb Space Telescope. The finding is puzzling because phosphine, a potential biosignature, has been missing from other similar objects. The detection may reveal how phosphorus behaves in low-metal environments or how stellar remnants like white dwarfs enrich their surroundings with this crucial element. Source link

Deep beneath the ocean, scientists uncovered thriving microbial life in one of Earth’s harshest environments—an area with a pH of 12, where survival seems nearly impossible. Using lipid biomarkers instead of DNA, researchers revealed how these microbes persist by metabolizing methane and sulfate. The discovery not only sheds light on deep-sea carbon cycling but also suggests that life may have originated in similar extreme conditions, offering a glimpse into both Earth’s past and the limits of life itself.

New research along Turkey’s Ayvalık coast reveals a once-submerged land bridge that may have helped early humans cross from Anatolia into Europe. Archaeologists uncovered 138 Paleolithic tools across 10 sites, indicating the region was a crucial migration corridor during the Ice Age. The findings challenge traditional migration theories centered on the Balkans and Levant, suggesting instead that humans used now-vanished pathways across the Aegean. Source link

From Cassini’s awe-inspiring flybys to cutting-edge simulations, scientists are decoding the secrets of Enceladus’s geysers. Supercomputer models show the icy moon’s plumes lose less mass than expected, refining our understanding of its mysterious interior.
