Phys.org / End of humanity? Blow‑by‑blow account of what would happen if the Yellowstone supervolcano erupted now
Around 631,000 years ago—a geological blink of an eye—catastrophe unfolded in what is now northwestern Wyoming, U.S. During what is thought to have been a series of immense volcanic eruptions, life within hundreds of kilometers ...
Phys.org / Satellite record reveals Arctic melt season has plateaued after decades of lengthening
For decades, Arctic sea ice has been melting earlier in spring and freezing later in fall, extending the melt season and contributing to widespread ice loss. A new NASA-led study published in Communications Earth & Environment ...
Phys.org / Cyanobacterium found in clean lakes shows little toxic potential
Gloeotrichia echinulata is a type of cyanobacterium that draws scrutiny because it tends to bloom in clear lakes, forming thick mats of visible green or white puffballs in otherwise clean water. Because of the slew of toxic ...
Phys.org / Two new large stick insect species discovered in Australia's backyards and rainforests
Insect "detectives" have discovered two new types of large stick insects, showing scientists are still uncovering new species in some of Australia's most well-studied landscapes. Researchers at the University of Sydney have ...
Tech Xplore / Snapping rods let frog-like robot outrun rigid legs across six terrains
Roboticists at the UCLA Samueli School of Engineering and the University of Michigan have shown that elastic rods can be bent and twisted to repeatedly snap between shapes, releasing built-up energy that enables small robots ...
Phys.org / A newly discovered mechanism helps cells prevent errors during DNA replication
At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart muscle cells divide ...
Phys.org / Archaeologists uncover centuries-old mystery of Tampa Bay's secret community of migrant potters
About 100 years ago, archaeologists unearthing pottery sherds in Tampa Bay found something unexpected. Some of the fragments they recovered had designs nearly identical to decorated pottery found hundreds of miles to the ...
Medical Xpress / RNA therapy may help preserve muscle during GLP-1 weight loss
GLP-1 drugs have revolutionized obesity treatment, but they can lead people to lose muscle mass along with fat. And when patients stop treatment, they often regain their weight—primarily as fat.
Phys.org / Longitudinal survey finds little evidence that social tech predicts life satisfaction in adults
Social technologies, digital tools that allow people to communicate and share content with each other online, have become a central way of communicating for many people worldwide. Yet the possible effects of these technologies ...
Medical Xpress / Engaging the core could regulate blood flow in the brain
Engaging core muscles—through movement, exercise or even coughing—may be a key regulator of blood flow in the brain. When the body moves, the contraction of abdominal muscles increases pressure in blood vessels connected ...
Phys.org / AI tool compares 125 cell types across 700 million years of evolution
A KAUST-led team has developed the AI tool Unify to help scientists compare similar cell types across distant species. This comparison can help researchers assess which findings from animal studies may be most relevant to ...
Phys.org / Eat, prey, love: Nurse shark mating and Northeast angler conflicts offer conservation insights
While the Discovery Channel's annual Shark Week event has given the public greater familiarity with sharks, much about them—from their mysterious love lives to how their eating habits bring them into conflict with recreational ...
