Oct. 5, 2025 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 ...

Oct. 5, 2025 Stanford scientists found that aging disrupts the brain’s internal navigation system in mice, mirroring spatial memory decline in humans. Older mice struggled to recall familiar locations, while a few “super-agers” retained youthful brain patterns. Genetic clues suggest some animals, and people, may be naturally resistant to cognitive aging. The discovery could pave the way for preventing ...

Oct. 5, 2025 Researchers from Leeds found that overeating is driven more by what people believe about food than by its actual ingredients or level of processing. Foods perceived as fatty, sweet, or highly processed were more likely to trigger indulgence. Surprisingly, the “ultra-processed” label explained almost none of the difference in overeating behavior. The findings suggest that perception and ...

Oct. 5, 2025 Researchers have uncovered how a protein called MRAP2 acts as a key regulator of hunger. It helps move the appetite receptor MC4R to the cell’s surface, allowing it to send stronger “stop eating” signals. The discovery offers new hope for tackling obesity by targeting this natural hunger ...

Oct. 3, 2025 Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region untouched by current observatories. Built with optical resonators and atomic clocks, the compact detectors can fit on a lab table yet probe signals from exotic binaries and ancient cosmic events. Unlike LIGO, they’re relatively immune to seismic noise and could start working long ...

Sep. 30, 2025 A new boron-rich compound, manganese diboride, delivers much higher energy density than current solid-rocket materials while remaining stable until intentionally ignited. Its power comes from an unusual, strained atomic structure formed during ultra-hot synthesis, with promising uses beyond ...

Oct. 5, 2025 New research reveals that deep-sea mining could dramatically threaten 30 species of sharks, rays, and ghost sharks whose habitats overlap with proposed mining zones. Many of these species, already at risk of extinction, could face increased dangers from seafloor disruptions and sediment plumes caused by mining ...

Oct. 3, 2025 Billions of years ago, Earth’s atmosphere was hostile, with barely any oxygen and toxic conditions for life. Researchers from the Earth-Life Science Institute studied Japan’s iron-rich hot springs, which mimic the ancient oceans, to uncover how early microbes survived. They discovered communities of bacteria that thrived on iron and tiny amounts of oxygen, forming ecosystems that recycled ...

Oct. 2, 2025 In 2020, California’s Creek Fire became so intense that it generated its own thunderstorm, a phenomenon called a pyrocumulonimbus cloud. For years, scientists struggled to replicate these explosive fire-born storms in climate models, leaving major gaps in understanding their global effects. Now, a new study has finally simulated them successfully, reproducing the Creek Fire’s storm and others ...

Oct. 1, 2025 Fungi may have shaped Earth’s landscapes long before plants appeared. By combining rare gene transfers with fossil evidence, researchers have traced fungal origins back nearly a billion years earlier than expected. These ancient fungi may have partnered with algae, recycling nutrients, breaking down rock, and creating primitive soils. Far from being silent background players, fungi were ...
