Phys.org / ISS study identifies thresholds for muscle atrophy and fiber changes in reduced gravity
It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in near-zero gravity (microgravity) environments. However, the gravity threshold needed to maintain sufficient ...
Medical Xpress / Thoughts don't kill people, but study suggests options for keeping guns from doing so
Millions of Americans have thought about shooting someone, a new University of Michigan study finds. And if they didn't already own a firearm, some of them have thought about getting one to make their thoughts a reality. ...
Phys.org / Do political social media ads influence the outcome of elections?
Social media platforms, such as Facebook, Instagram and X, are accessed daily by millions of people worldwide. In the weeks or months leading up to elections, many political parties use social media platforms as part of their ...
Medical Xpress / The Alzheimer's gut-brain link: How butyrate could curb amyloid-β buildup and inflammation
Alzheimer's disease (AD) is a neurodegenerative disease that causes progressive memory loss and a significant decline in mental functions. Past studies have shown that people with AD exhibit a buildup of a protein called ...
Medical Xpress / Stem cell therapy shows promise for reversing aging-related frailty in new clinical trial
Stem cells are gaining attention for their potential to treat leukemia, certain solid tumor cancers, and inherited metabolic disorders. Now, a clinical trial reports that a single dose can significantly improve physical strength ...
Phys.org / Globular cluster NGC 5824 is embedded in a dark matter halo, study suggests
Using data from the Magellan Clay telescope and the Canada-France-Hawaii Telescope (CFHT), astronomers have investigated a galactic globular cluster known as NGC 5824. Results of the new study, available in a paper published ...
Phys.org / Warmer, wetter cyclone weather made Peru's dengue outbreak 10 times larger, study finds
Diseases historically absent from the United States have been showing up in Florida, Texas, California and other U.S. states in recent years. To understand why, look to Peru. That's where researchers from Stanford and other ...
Medical Xpress / Three anesthesia drugs all have the same effect in the brain, researchers find
When patients undergo general anesthesia, doctors can choose among several drugs. Although each of these drugs acts on neurons in different ways, they all lead to the same result: a disruption of the brain's balance between ...
Phys.org / Charcoal records reveal 'unprecedented' wildfires in tropical peatlands during 20th century
A new study reveals an unprecedented increase in wildfires in tropical peatlands during the 20th century. "Unprecedented burning in tropical peatlands during the 20th century compared to the previous two millennia" is published ...
Phys.org / Large craters offer clues to the origin of asteroid 16 Psyche
Even 200 years after asteroid 16 Psyche was discovered, astronomers continue to puzzle over its formation. Psyche is the 10th-most massive asteroid in the main belt between Mars and Jupiter, and the largest known metallic ...
Phys.org / Turning mosquitoes into flying vaccine carriers to protect against bat-borne viruses
Bats are reservoirs for several zoonotic viruses, such as Ebola and coronaviruses. These pathogens can spread to humans through direct contact with the flying mammals or their bodily fluids, or indirectly through contaminated ...
Tech Xplore / Communication-aware neural networks could advance edge computing
Edge computing is an emerging IT architecture that enables the processing of data locally by smartphones, autonomous vehicles, local servers, and other IoT devices instead of sending it to be processed at a centralized large ...
