Phys.org / Early human embryonic cells may be vulnerable to SARS-CoV-2 infection
A University of California, Riverside study reports that cells in the earliest stages of human development could be susceptible to infection by SARS-CoV-2, which causes COVID-19, offering new insight into how the virus interacts ...
Medical Xpress / The Bondi Beach terror attack mobilized a team of volunteer medics. Here's what we learned
Warning: this article contains details of injuries sustained during a terrorist attack.
Medical Xpress / Cold skin, hot heart, one gene: Hidden temperature switch decides where disease appears
The saying "cold hands, warm heart" is usually meant metaphorically—but new research from UC Davis School of Medicine and collaborating institutions suggests it has a striking biological parallel.
Tech Xplore / Human-guided AI system could strengthen advanced reactor monitoring and control
Nuclear reactors generate reliable, low-carbon electricity by using heat from nuclear fission to turn turbines. These steady energy producers are a crucial component of clean power generation. Nuclear engineers are responsible ...
Medical Xpress / Blocking stress signals could limit harmful inflammation after heart attack
After a heart attack, the body rapidly floods the injured heart with neutrophils—white blood cells that help repair damage but can also make it worse when too many arrive too quickly. New research from the University of Oklahoma ...
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), ...
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 / 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 / An interplanetary shortcut can speed up trips to Mars
Whether it's robotic rovers heading to Mars or, one day, a crew of astronauts, a round-trip journey is an incredibly long one. But there may be a way to find a shortcut. A new study published in the journal Acta Astronautica ...
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 / 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 / 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 ...
