Phys.org / Iron and blue LEDs synthesize natural molecules, cutting the need for expensive chiral components
Photocatalysts facilitate chemical reactions by absorbing light. Metal-based photocatalysts are widely used in organic synthesis due to their durability and the ability to tune their function by modifying the ligands attached ...
Phys.org / E-waste chemicals are appearing in dolphins and porpoises
Liquid crystal monomers (LCMs) are critical components of laptop, television, and smartphone screens. Given their ubiquity in the environment, these compounds are considered persistent pollutants, posing threats to marine ...
Phys.org / Ocean warming drives a nearly 20% annual decline in fish biomass, research confirms
According to a new study by the Museo Nacional de Ciencias Naturales (MNCN-CSIC) and the National University of Colombia, chronic ocean warming is driving a nearly 20% annual decline in fish biomass. However, the researchers ...
Phys.org / Heat relief means higher emissions: How air conditioning complicates 1.5°C goals
While air conditioning protects people from dangerous heat, it also significantly worsens global warming—by 2050, potentially producing more carbon dioxide than the current annual emissions of the United States, a new study ...
Phys.org / Celebrity dolphin of Venice doesn't need special protection—except from humans
Bottlenose dolphins usually live in small to medium-sized groups in coastal and open-sea waters, but every once in a while, a dolphin might leave its pod behind, flock to coastal areas and approach human settlements. While ...
Phys.org / Urine tests confirm alcohol consumption in wild African chimpanzees
Aleksey Maro knows far more than he cares to know about the urination habits of chimpanzees. But if you want to measure the alcohol intake of chimps in a Ugandan rain forest, where a breathalyzer is impractical, collecting ...
Phys.org / Quantum effect could power the next generation of battery-free devices
A new study has revealed how tiny imperfections and vibrations inside a promising quantum material could be used to control an unusual quantum effect, opening new possibilities for smaller, faster, and more efficient energy-harvesting ...
Phys.org / Surprise solar eruptions on sun's far side validate new forecasting method
A team of scientists from around the world has created the first system that can predict when and where extremely powerful solar storms, called superflares, are most likely to happen. These storms can disrupt power grids, ...
Phys.org / Why do female caribou have antlers? Arctic study points to nutrition
Biologists have long wondered why caribou are the only deer in the world in which females—like males—have antlers. A study of shed antlers collected from calving grounds in the Arctic National Wildlife Refuge provides ...
Phys.org / Canada's Magdalen Islands' peatlands hold vital clues about ancient Atlantic hurricanes
Eastern Canada has seen a rise in the number of hurricane- and near-hurricane strength events battering its maritime areas, with particularly violent storms in 2003 (Hurricane Juan), 2019 (Dorian) and 2022 (Fiona). While ...
Phys.org / Nine-city study finds richer neighborhoods get more sidewalk shade
One of the best forms of heat relief is pretty simple: trees. In cities, as studies have documented, more tree cover lowers surface temperatures and heat-related health risks. However, as a new study led by MIT researchers ...
Phys.org / Why do microbes team up? A new model explains nutrient sharing in fluctuating environments
Depending on others for something you need may feel like a risky proposition—and perhaps a human one. It is actually a survival strategy found in the microbial world, and far more frequently than one might expect. Discovering ...
