Phys.org / Supercomputer simulations test turbulence theories at record 35 trillion grid points
Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence ...
Phys.org / Can life begin on a moon without a sun?
Free-floating planets, or as they are more commonly known, rogue planets, wander interstellar space completely alone. Saying there might be a lot of them is a bit of an understatement. Recent estimates put the number of rogue ...
Phys.org / Half of the world's coral reefs suffered major bleaching during the 2014–2017 global heat wave, estimates suggest
Benefits to society from coral reefs, including fisheries, tourism, coastal protection, pharmaceutical discovery and more, are estimated at about $9.8 trillion per year. For the first time, an international team led by Smithsonian ...
Phys.org / NASA's SPHEREx mission spots 3I/ATLAS's bright envelope
NASA's Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) was built for the ambitious purpose of performing an all-sky survey. The data it collects from more than 450 million ...
Phys.org / Sleek, lithe and extremely rare: This elusive California fox has finally been GPS-collared
The stunning Sierra Nevada red fox is one of the nation's rarest and most critically threatened mammals, with fewer than 50 believed to remain in the Sierra. And now, for the first time, a specimen has been successfully GPS-collared ...
Phys.org / Egalitarianism among hunter-gatherers? What a food-sharing experiment reveals about self-interest
Hunter-gatherers like the Hadza of Tanzania are famous for their egalitarianism. A resource redistribution experiment conducted with the Hadza suggests many tolerate inequality—as long as it benefits themselves. Published ...
Tech Xplore / Ultrafast nanolasers mimic how the brain imagines unseen parts of the world
A new study has demonstrated how networks of spiking nanolasers could emulate a key principle of brain function: to imagine things that we cannot directly perceive by sampling from internal models of the world. The study, ...
Medical Xpress / In comparing real-world costs and benefits of fibromyalgia medications, a clear winner emerges
Fibromyalgia is a long-term chronic condition that causes widespread pain in the muscles and soft tissues throughout the body. The illness can affect people of all ages and has a major impact on quality of life, often making ...
Phys.org / Deep learning detects foodborne bacteria within three hours by eliminating debris misclassifications
Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria. Current methods to ...
Phys.org / What to know about EPA decision to revoke a scientific finding that helped fight climate change
The Environmental Protection Agency on Thursday revoked its own 2009 "endangerment finding," a scientific conclusion that for 16 years has been the central basis for regulating planet-warming emissions from power plants, ...
Medical Xpress / Gamma-synced brain stimulation can nudge people to behave less selfishly
Stimulating two brain areas, nudging them to collectively fire in the same way, increases a person's ability to behave altruistically, according to a study published in the PLOS Biology by Jie Hu from East China Normal University ...
Phys.org / Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve ...
