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 / 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 / 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 ...
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 ...
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 ...
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.
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 ...
Dialog / From spider webs to mosaics: How nanosheets of graphene oxide control the patterns left by a drying droplet
A drop of coffee on a tabletop often leaves a dark ring behind. This everyday mark is a reminder that a drying droplet is not passive: As water evaporates, it can transport the particles suspended inside it toward the edge. ...
Phys.org / Student-led missions deploy free-flying light sails from CubeSats in low Earth orbit
Students in Cornell's Space Systems Design Studio (SSDS) have released mission results for two unique light-sail experiments. These sails are slightly larger than a pizza box and harness momentum from photons to accelerate ...
