French firefighters face 'pyrocumulonimbus' for first time
The gigantic wildfire ravaging southwestern France has created an extremely dangerous "pyrocumulonimbus"—a phenomenon never before seen in the country—the spokesman for the country's National Firefighters Federation of France (FNSPF) told AFP.
Whales at risk, hungry pelicans: Marine heat wave hits California
On a boat off the coast of California, Sara Lesser gazes wistfully at dozens of dolphins playing in the vessel's wake. This summer, extreme heat is making such a scene increasingly rare.
France, Spain battle 'monster' wildfires with more heat on the way
Firefighters battled massive blazes tearing through forests across France and Spain on Monday, as authorities warned of a fresh heat wave set to engulf the scorched French wine-growing region around the major city of Bordeaux.
Saber-toothed cats' spinal tumors suggest inbred species struggled to survive
The fossilized spines of saber-toothed cats in the La Brea Tar Pits reveal evidence of an unexpectedly high prevalence of rare spinal nerve tumors, suggesting that the species became inbred just before extinction. These tumors, which cause significant pain and reduced limb
Spines of saber-toothed cats tell a tale of the doomed species
Remains pulled from the La Brea Tar Pits revealed deformed vertebrae and rare tumors, possible signs of inbreeding among now-extinct saber-toothed cats.
Tigray's old grapevines have survived against the odds: New research uncovers their genetic and historic value
The northern highlands of Ethiopia are among Africa's oldest agricultural landscapes. Some of the world's most important crops originated here, particularly pulses and grains, including teff. Yet another crop has a less well-known history in Ethiopia's Tigray region: the
Near a black hole, gravity changes a quantum circuit's readings, not its rules
Imagine holding one of our most precise quantum devices at a fixed position outside a black hole. A Josephson junction—two superconductors separated by an ultrathin barrier—can turn a voltage into a quantum oscillation with extraordinary precision. Would intense gravity change
Forest productivity, not rapid warming, shapes Northern Eurasia's carbon sink
Northern Eurasia contains about 20% of the world's forests and plays a crucial role in mitigating climate change by absorbing atmospheric carbon dioxide, thereby acting as a major carbon sink. However, understanding the region's carbon sink is challenging because it is
Twisted laser light distinguishes mirror-image molecules by their fragment counts
Many molecules exist in two mirror-image forms—like left and right hands—that look identical but can behave very differently, especially in biological systems and pharmaceuticals. Distinguishing between these enantiomers (also called chiral molecules) is a longstanding
When a teenager makes the 'stupid choice,' their brain is working exactly as designed
When an adult refuses to let an injustice pass—stands up to a bully or asserts their rights—we call it principle. When a 15-year-old retaliates to an insult thrown in a school corridor, risking detention, we call it a failure to think ahead. It's easy to ascribe this to a
Gamma-ray pulsations reveal extreme 3.2-millisecond pulsar 3,900 light-years away
By analyzing the data from NASA's Fermi gamma-ray space telescope, Chinese astronomers have investigated a recently identified millisecond pulsar known as PSR J0435+3233. As a result, they found that the pulsar exhibits gamma-ray pulsations. The discovery was detailed in a
Trace molecules emerge as chemical 'keystones' that steer life's communities
In nature, the rarest ingredient can be the one that holds everything together. In a new article published in Trends in Ecology & Evolution, Dr. Erika C. Freeman of the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin argues that a handful of scarce
A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous technologies, ranging from refrigerators to power
DNA vacuum captures animal traces from air to map Danish wildlife
Researchers have developed a DNA vacuum that can suck genetic traces from animals out of the air and reveal which animals live in an area. In two new studies, the researchers collected air samples in three natural areas in Denmark and showed that the method can be used to map
Jimothy the Raccoon Survived Against the Odds, a Testament to Sophisticated Brains and Devoted Mothers
Surviving in the wild is no small feat for animals, especially ones like Jimothy, with rare conditions and yet he persevered to viral celebration, thanks to an adaptable brain and a caring mother The post Jimothy the Raccoon Survived Against the Odds, a Testament to
Angola's oldest burials, including its only known ancient cremation, uncovered at a 15th-century site doomed by a dam
As the construction of a hydroelectric dam loomed, archaeologists raced to uncover Angola's earliest dated burials and its only known cremation at a 15th-century settlement before it vanished beneath the water.
As wildfires grip France and Spain, what are the risks from the smoke?
What dangers does smoke from wildfires pose? Who is most at risk? Here are some answers to health questions often asked, especially now with fires in France and Spain.
A hidden Alzheimer’s tipping point may decide who gets dementia
Scientists have identified a possible tipping point that helps determine whether Alzheimer’s-related brain changes lead to dementia. The key may lie in how the brain’s immune cells respond to plaques and tau, offering a promising new target for treatments designed to extend
550 years later, scientists claim to have solved what killed Botticelli’s muse
Italian Renaissance painter Sandro Botticelli painted Simonetta Vespucci as Venus rising from the waves. Now, scientists think they’ve solved how she died
Scotland declares 'major' wildfire in Cairngorms national park
Scottish firefighters fought a wildfire Saturday that was burning through Cairngorms National Park in the north, with authorities advising residents to evacuate.
Thousands crowd shelters as wildfires force exodus in France, Spain
Thousands crowded into emergency shelters in France and Spain on Sunday after wildfires drove more than 300,000 people to flee their homes and vacation accommodations.
