Phys.org / Trees may store less carbon than expected in the future
It's intuitive to think that if a tree is photosynthesizing, it's also growing. But that's not necessarily so—and a new study of oak trees, published in the journal Science Advances, found that even as they photosynthesize ...
Phys.org / Cellulose films match plastic performance while enabling recycling or biodegradation
A new cellulose-based material platform developed in Finland responds to tightening regulatory requirements and industry pressure to both replace and reduce plastic in packaging, including emerging thresholds such as limiting ...
Phys.org / Rare deep-sea goblin sharks filmed in natural habitat for first time
The first published live observations of the rare goblin shark (Mitsukurina owstoni) in its natural deep-ocean habitat were reported in a new paper by a University of Hawai'i at Mānoa-led team of oceanographers. In the past, ...
Phys.org / Jurassic viral gene may have helped apple snails start laying eggs on land
Pomacea canaliculata, commonly known as the apple snail, is a pest commonly found in Hong Kong's wetlands and farmlands. It feeds on aquatic plants and produces toxic pink egg masses resembling miniature grapes that adhere ...
Medical Xpress / Shared recollections of events linked to similar brain activity patterns
People who attended or experienced the same event often remember it in completely different ways. For instance, one person might remember a family dinner as warm and enjoyable, while another might recall that the same dinner ...
Phys.org / Unique chromium beam experiment unlocks cosmic ray origins and galactic chemistry
When a star dies, it generates an explosion of elemental nuclei and hurls them into space. Those elements, called cosmic rays, travel at nearly the speed of light, and eventually some of them encounter manmade detectors. ...
Phys.org / Dragonfly and damselfly migrations crisscross planet, with 100 species confirmed
Migration flights of dragonflies and damselflies crisscross much of our planet, new research reveals. Scientists from the universities of Exeter and Lund reviewed global evidence and found 100 dragonfly and damselfly species ...
Medical Xpress / Our brains may be automatically filtering out negative words
We tend to assume that emotionally charged words are more likely to grab our attention. An insult shouted across a crowded room or a disturbing phrase overheard on television can seem impossible to ignore. But a new study ...
Phys.org / 'Selection shadow' may explain why longer lives bring more age-related disease
A review article now published in Nature Reviews Genetics brings together evolutionary theory, comparative genomics and large-scale human genetics to explain why we age and why aging rates differ among individuals and species. ...
Tech Xplore / New strategy enhances oxygen reduction in zinc-air batteries
Batteries are undergoing rapid advances. For example, modern zinc-air batteries have the remarkable ability to use oxygen as energy—but that oxygen isn't stored in the battery itself. Zinc-air batteries take in surrounding ...
Phys.org / One photon, two reactions—new catalyst converts CO₂ and biowaste simultaneously
Researchers have developed a solar-driven catalyst material that harnesses the energy of a single photon to reduce carbon dioxide and oxidize organic waste at the same time, producing valuable chemicals in both reactions.
Phys.org / Climate change is causing fish to move to cooler water—what if their escape route is blocked?
Around the world, ocean warming is causing fish to move poleward in search of cooler water.
