TRAPPIST-1e, an Earth-sized world in the system's habitable zone, is drawing scientific attention as researchers hunt for signs of an atmosphere--and potentially life-supporting conditions. Early James Webb observations hint at methane, but the ...

A sudden, unexplained mass die-off is decimating sea urchins around the world, including catastrophic losses in the Canary Islands. Key reef-grazing species are reaching historic lows, and their ability to reproduce has nearly halted in some regions. ...

Fossils from Qatar have revealed a small, newly identified sea cow species that lived in the Arabian Gulf more than 20 million years ago. The site contains the densest known collection of fossil sea cow bones, showing that these animals once thrived ...

Researchers discovered that nerve injuries can alter the immune system throughout the body, and males and females react very differently. Male mice showed strong inflammatory responses, while females showed none, yet both transmitted pain-inducing .. ...

Researchers found that eroded lava rubble beneath the South Atlantic can trap enormous amounts of CO2 for tens of millions of years. These porous breccia deposits store far more carbon than previously sampled ocean crust. The discovery reshapes how . ...

Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility ...

Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to maintain long, healthy telomeres. When RPA malfunctions, telomeres can shorten dangerously, leading to serious diseases.

Scientists tracking young Arizona Bald Eagles found that many migrate north during summer and fall, bucking the traditional southbound pattern of most birds. Their routes rely heavily on historic stopover lakes and rivers, and often extend deep into ...

A new economic modeling tool is helping Maine kelp farmers identify cost-saving strategies with remarkable precision. By analyzing farm design, weather, vessel types, and processing methods, it highlights how decisions ripple through overall ...

Scientists developed a high-performance hydrogen-production catalyst using lignin, a common waste product from paper and biorefinery processes. The nickel-iron oxide nanoparticles embedded in carbon fibers deliver fast kinetics, long-term durability, ...
