Explosive origins of 'secondary' ice and snow

Scientists publish new direct evidence that shattering drizzle droplets drive explosive 'ice multiplication' events. The findings have implications for weather forecasts, climate modeling, water supplies -- and even energy and transportation infrastructure.

What early-budding trees tell us about genetics, climate change

Late frosts have caused millions of dollars in losses for orchards over the years. Scientists are investigating the genes that tell trees when to bud out and blossom. A deep understanding of the genetics of bud-break enables scientists to modify or select crop varieties more resilient to late frost, warming winters, diseases and pests.

Ultra-sensitive flow microsensors

A team of scientists have developed the thinnest and most sensitive flow sensor, which could have significant implications for medical research and applications, according to new research.

How a lithium-metal electrode ages

Even when a device is turned off, its battery gradually loses its charge and eventually some of its capacity for storing energy. Scientists have now documented this aging process in next-gen lithium-metal electrodes.

Worth one's salt: An ancient Maya commodity

The first documented record of salt as an ancient Maya commodity at a marketplace is depicted in a mural painted more than 2,500 years ago at Calakmul, a UNESCO World Heritage site in the Yucatan Peninsula in Mexico. Salt cakes could have been easily transported in canoes along the coast and up rivers in southern Belize, according to archaeologists.

Researchers tackle the 'spiders' from Mars

Researchers have been shedding light on the enigmatic 'spiders from Mars', providing the first physical evidence that these unique features on the planet's surface can be formed by the sublimation of CO2 ice.

Electrode interphase formation

Batteries charge and recharge -- apparently all thanks to a perfect interplay of electrode material and electrolyte. However, for ideal battery function, the solid electrolyte interphase (SEI) plays a crucial role. Materials scientists have now studied nucleation and growth of this layer in atomic detail. The properties of anions and solvent molecules need to be well balanced.

Arctic methane release due to melting ice is likely to happen again

Beneath the cold, dark depths of the Arctic ocean sit vast reserves of methane. These stores rest in a delicate balance, stable as a solid called methane hydrates, at very specific pressures and temperatures. If that balance gets tipped, the methane can get released into the water above and eventually make its way to the atmosphere.

Researchers create map of potential undiscovered life

Less than a decade after unveiling the 'Map of Life,' a global database that marks the distribution of known species across the planet, researchers have launched an even more ambitious and perhaps important project -- creating a map of where life has yet to be discovered. For Walter Jetz, a professor of ecology and evolutionary biology at Yale who spearheaded the Map of Life project, the new...

Predicting who may do best with psychedelic-assisted therapy

As psychedelics gain ground as a potential therapy for mental health disorders, there remains a pressing concern that patients in clinical trials may have adverse effects to the drugs. New research identifies personality traits that have been associated with positive and negative experiences on psychedelics in previous studies, information that could help predict how future clinical trial...
