Medical Xpress / Discovery reveals aging human brains receive immune cell reinforcements from blood
The brain's immune system has long been thought to exist independently from the rest of the body, complete with its own specialized immune cells and a blood-brain barrier that limits what can travel into the brain.
Medical Xpress / Trauma analysis finds brain injuries more common among e-scooter riders than motorcyclists
E-scooter riders in England and Wales may face a higher risk of brain and internal organ injuries than motorcyclists and cyclists, according to a study published in Scientific Reports. The authors recommend increasing e-scooter ...
Phys.org / DESI side project reveals the spectra of disintegrated exoplanets
Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while ...
Medical Xpress / Expert shares practical tips for treating hair loss
Hair loss is often caused by a combination of heredity and aging, says Dr. Dawn Davis, a Mayo Clinic dermatologist. Treatments that may slow that type of hair loss and help regrow hair, including over-the-counter therapies ...
Medical Xpress / Social prescribing boosts health checks without raising costs
Patients referred to social prescribing are more likely to seek health care in the short term but could end up needing their primary care physician less often within a year, according to a new study by University of Manchester ...
Phys.org / Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up ...
Phys.org / A new species of Ice Age toad discovered at La Brea Tar Pits: The spadefoot toad Spea labreae
For the first time, researchers have discovered a new species of extinct amphibian from Ice Age Los Angeles at La Brea Tar Pits: a spadefoot toad they have named Spea labreae. Only one other extinct Pleistocene amphibian ...
Phys.org / Liquid nitrogen may have recently flowed across Pluto's heart-shaped glacier
A new study led by Southwest Research Institute (SwRI) provides evidence that liquid nitrogen is rising to Pluto's surface through cracks at the northern edge of Sputnik Planitia, part of the massive heart-shaped glacier ...
Tech Xplore / Pagoda-inspired floors reduce tower sway while cutting material needs
Imperial and Arup pioneer a new approach to designing tall buildings that uses the building's own weight to reduce movement in high winds and earthquakes. Inspired by traditional Japanese pagodas, it makes towers safer while ...
Phys.org / One ant can trigger colony-wide activity bursts, mathematical model suggests
Scientists have long known that ant colonies sometimes seem to move as one. A nest that appears quiet can suddenly erupt into activity, with workers throughout the colony springing into motion almost simultaneously before ...
Medical Xpress / Wildfires now the dominant contributor to unhealthy levels of air pollution for pregnant women in the US
Wildfires are well-known health risks. Now, in a new Frontiers in Environmental Health study, researchers in the U.S. have—for the first time—evaluated how prenatal PM2.5 exposure has changed over space and time on a national ...
Medical Xpress / How multinucleated cells help the brain reorganize after localized astrocyte loss
The human brain contains various types of cells that collectively support its functions. In addition to neurons, nerve cells that communicate via electrical and chemical signals, it also relies on star-shaped cells known ...
