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 / 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.
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 / NASA Laser Terminal enhances views during Artemis II mission
Millions of people watched the historic launch of Artemis II and were captivated by the mission's 10-day journey around the moon as NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space ...
Medical Xpress / FDA approves once-daily Idvynso tablet for treating HIV
The U.S. Food and Drug Administration has approved Merck's Idvynso (doravirine/islatravir), a new, once-daily, two-drug single tablet for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen ...
Medical Xpress / Dietary fats shape pancreatic cancer risk via ferroptosis
For decades, the relationship between fat and cancer has been treated as a question of quantity: Eat less fat, reduce your risk of developing cancer. But new research published April 29 in Cancer Discovery shows that for ...
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 / 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 / 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 / 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 ...
