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 ...
Medical Xpress / Long-term brain effects of COVID-19 vs. flu: Study reveals key differences
Even a mild case of COVID-19 or the flu can impact the body long after the fever and cough fade, according to new Tulane University research that may help explain why some people struggle to feel fully recovered weeks or ...
Phys.org / How many bee species exist? New global count puts the total near 26,000
The world has far more bees than anyone realized. Scientists have, for the first time, estimated just how many species of bees are out there on a global scale, offering a clearer look at how these vital pollinators are distributed ...
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 / Major gap in Earth's rock record likely due to tectonics—not glaciers
The Great Unconformity is a major gap in Earth's geologic record. The missing layer between Precambrian and Cambrian rocks represents a gap of around a billion years of history. Among much debate surrounding the cause of ...
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 / How AI can improve the quality of peer review
A new AI coach for scientists has been shown to significantly improve the quality of peer reviews, making them clearer and more helpful for authors. Peer review is essential to ensuring the integrity of scientific publications, ...
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 / 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 / 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 / Color-changing nanopigment sensor tracks pH one to ten with stable, repeatable readings
Chemists in South Korea have created a stable color-changing sensor that displays an easily quantifiable response to the pH of its surroundings. Published in Microsystems & Nanoengineering, Dong-Hwan Kim and colleagues at ...
Phys.org / Thunderstorms conjure ghostly coronae in treetops, observed outdoors for the first time
For the first time, researchers have observed and measured weak electrical discharges, known as coronae, on trees during thunderstorms. A new study describes the near-invisible sparkles appearing similarly on branches of ...
