Phys.org / Pegasus launch to deploy LINK for months‑long orbit boost of aging Swift
A mission to raise the orbit of NASA's Neil Gehrels Swift Observatory is poised for launch no earlier than Tuesday, June 30, at 6:23 a.m. EDT (10:23 p.m. UTC+12), from Kwajalein Atoll, part of the Republic of the Marshall ...
Phys.org / Ocean warming above 1.5°C triggered year-round marine disruption across globe, study shows
Researchers at King Abdullah University of Science and Technology (KAUST) led one of the first global assessments of how marine ecosystems responded during the first year when global temperatures temporarily exceeded 1.5°C ...
Phys.org / Evidence identifies ancient Aboriginal mining in the Riverland
Flinders University researchers, in partnership with the River Murray and Mallee Aboriginal Corporation, have found evidence that points to 7,000 years of Aboriginal mining of stone at Sugarloaf Hill in South Australia's ...
Phys.org / Glass cells of atoms offer a new path to smarter, cheaper sensors
More accurate navigation systems and improved wireless communications may not come from traditional electronics, but rather from atoms. Researchers at Penn State and the National Institute of Standards and Technology (NIST) ...
Medical Xpress / AI-guided microneedles bend at body temperature to speed diabetic wound healing
Chronic wounds remain a major health care challenge, especially for people with diabetes, who often experience delayed healing, persistent inflammation and a higher risk of infection. Traditional wound-closure methods such ...
Phys.org / Novel crystal strategy delivers near-perfect zero thermal expansion from 11 K to 893 K
Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute ...
Phys.org / ROS-producing enzymes guide plant cell division and tissue patterning, gene-editing study shows
Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling. While ROS are established ...
Phys.org / May 2024 superstorm drew most ring current ions from Earth, not solar wind, research reveals
In May 2024, auroras were observed at unusually low latitudes across the globe, lighting up skies that rarely see such displays. Inside Earth's magnetosphere, the region of space surrounding our planet and dominated by its ...
Phys.org / Uranus, Neptune may be magma worlds, not ice giants
Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their "ice giant" moniker comes ...
Phys.org / Participatory theater helps young people become active citizens
In Estonian schools, social studies classes provide a thorough education on what democracy is and what it means to be a citizen. However, knowledge alone is not enough to foster active citizenship or reduce the differences ...
Phys.org / Rising heat and humidity challenge energy-efficient data center cooling worldwide
Reliable operation of data centers has become essential to nearly all sectors of modern society, including health care, education, government services, power grid operation, banking, defense and disaster relief. New research ...
Medical Xpress / Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary communication
The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have known about this signaling ...
