An international research team has identified a remarkable insect fossil from western Texas that could represent a crucial missing link in the story of insect evolution. The fossil, from the Late Mississippian period approximately 324 million years ago, belongs to a stem group of insects and may help scientists understand how these early insects transitioned from aquatic to terrestrial environments.

For years, conservationists have judged our impact on wildlife mostly by what we build: roads, farms, housing estates, fences. A sweeping new tracking study suggests that measure misses something important.

For years, the Dead Sea presented scientists with a genuine puzzle. Its upper waters, warmed by relentless sun and thickened by evaporation, seemed to shed salt each summer rather than accumulate it, while the lakebed far below kept gaining a fresh crust of crystals regardless of season.

Expired dairy products can become a disposal problem, but researchers have tested a different use for them. In a greenhouse experiment, scientists extracted protein-rich material from expired milk, yogurt and cheese, dried it into a powder and mixed it into sandy soil used to grow wheat.

Red dye moving through Missouri's Big Piney River has helped scientists visualise how genetic traces left by animals travel through flowing water. According to the U.S.

Between 2015 and 2017, researchers dropped four brightly coloured, food-grade dyes into five sinkholes scattered across the North Rim of the Grand Canyon and then waited to see where the water carrying them would resurface. Although researchers selected sinkholes known to funnel water underground, they did not know which springs the dyes would reach or how quickly they would travel.

Rather than predicting sudden apocalyptic bursts, scientists emphasise early warning systems, real-time lake-level monitoring, and controlled siphoning

In Canada, wood waste from logging and areas affected by wildfires is finding an unexpected fate. A new pilot in the country has begun converting this material into a lightweight, biodegradable wood foam designed to replace products made with plastic foam, according to information released by the University of British Columbia (UBC).

In the cool, wet upland streams of Queensland's Wet Tropics, several species of rainforest frog were pushed to the brink in the 1980s and 1990s by chytrid fungus, an aquatic pathogen that attacks frog skin and has driven extinctions worldwide. For decades, researchers lacked clear data on whether some of these species still persisted in remote creeks or had vanished entirely.

A fish pulled from a Minnesota lake turned out to be older than most great-grandparents. Scientists confirmed that a bigmouth buffalo, a species long dismissed by anglers as a nuisance, lived to age 112, making it the oldest verified freshwater bony fish on record.
