Phys.org / Tokamak regime sustains stable fusion plasma for one minute while easing heat loads
For the first time, a research team has demonstrated, in a metal-wall environment, a plasma regime that simultaneously achieves partial divertor detachment, an edge-localized-mode (ELM)-free high-confinement mode (H-mode), ...
Tech Xplore / Robots can run a marathon and play ping pong. But will they ever achieve true sporting greatness?
A humanoid robot recently made headlines around the world for running a half-marathon and beating the human world record. Around the same time, an AI-powered robot defeated an elite human player in table tennis. What the ...
Phys.org / Physicists have measured 'negative time' in the lab
As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands, but mostly dwelt with the nymph Calypso on her island. We can imagine that his wife, Penelope, would ...
Phys.org / Bees can detect viruses in food sources, but don't necessarily avoid them
The ability to detect viruses and other harmful pathogens is highly advantageous for animals, as it can guide their behavior and prevent them from illness, and—in severe cases—death. When it comes to species that live in ...
Phys.org / Frozen-in gravity: A new way to understand the evolution of spacetime dynamics
The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many physicists worldwide. Spacetime is described mathematically as a four-dimensional (4D) continuum ...
Phys.org / 5th-century Belgian burial with 'scrap metal' may reveal missing link between Roman and Merovingian monetary systems
A study published in the journal Britannia analyzed coins and metal items found in an early 5th-century AD burial in Oudenburg, Belgium. The burial occurred around the same time that base metal coins ceased arriving in northwestern ...
Phys.org / Thinner than hair and stretchable like rubber, this new shield tackles a space-age problem in one layer
Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic ...
Phys.org / DESI-HVS1 is an old hypervelocity star ejected from the galactic center, observations suggest
Chinese astronomers report the discovery of DESI-HVS1, which may be an old metal-poor hypervelocity star of galactic center origin. The finding, based on the data from the Dark Energy Spectroscopic Instrument (DESI) and ESA's ...
Phys.org / NASA connects little red dots with Chandra and Webb
A newly discovered object may be a key to unlocking the true nature of a mysterious class of sources that astronomers have found in the early universe in recent years. A "X-ray dot" found by NASA's Chandra X-ray Observatory ...
Phys.org / Drivers help study road-trip mystery: what became of bug splats?
Long an emblem of the summer road trip, squashed bugs on the car have become less numerous over the years, many people say—causing concern about the health of the world's insect populations.
Phys.org / How a free flow of information can amplify incorrect ideas
The idea that information should flow freely is deeply embedded in the design of social media. The assumption is that the more information is produced and shared, the better. However, simulations by a team of scientists including ...
Phys.org / Europe's seafloor fishing looks profitable until societal costs turn the math upside down
The first study to measure the full economic value of bottom trawling in Europe's waters calculates that the destructive fishing practice imposes up to €16 billion annually in net costs to society. The research is published ...
