Medical Xpress / Scientists create 'smart underwear' to measure human flatulence
Scientists at the University of Maryland have created Smart Underwear, the first wearable device designed to measure human flatulence. By tracking hydrogen in flatus, the device helps scientists revisit long-standing assumptions ...
Dialog / How charges invert a long-standing empirical law in glass physics
If you've ever watched a glass blower at work, you've seen a material behaving in a very special way. As it cools, the viscosity of molten glass increases steadily but gradually, allowing it to be shaped without a mold. Physicists ...
Phys.org / Satellite record shows boreal forests expanded 12% and shifted north since 1985
The boreal forest—the world's largest terrestrial biome—is warming faster than any other forest type. To understand the changing dynamics of boreal forests, Min Feng and colleagues analyzed the biome from 1985 to 2020, ...
Medical Xpress / Specific brain signals rapidly eliminate body fat in mice
Researchers at WashU Medicine have identified a potent pathway that begins in the brain and leads to loss of all body fat without reducing food intake. The study is reported in Nature Metabolism.
Medical Xpress / Nonablative radiofrequency may improve sexual function in postmenopausal women
Hormone declines during menopause can cause genitourinary syndrome of menopause (GSM), a cluster of vulvovaginal and urinary symptoms that can significantly impair a woman's quality of life. Local estrogen therapy is effective ...
Phys.org / How giant galaxies could form just 1.4 billion years after the Big Bang
The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international team led by Nikolaus Sulzenauer and Axel Weiß from the Max Planck Institute for Radio Astronomy ...
Phys.org / Can life begin on a moon without a sun?
Free-floating planets, or as they are more commonly known, rogue planets, wander interstellar space completely alone. Saying there might be a lot of them is a bit of an understatement. Recent estimates put the number of rogue ...
Phys.org / Mauled by a bear, 27,500 years ago: What a lavish teen burial reveals
A teenager's skeleton lay supine in a shallow pit on a bed of red ocher, his remains adorned with several ivory pendants, four perforated antler batons, mammoth ivory pendants, and a flint blade, his skull decorated with ...
Medical Xpress / Rejuvenating neurons restores learning and memory in mice
Age-related memory decline and neurodegenerative diseases like Alzheimer's are often thought of as irreversible. But the brain is not static; neurons continually adjust the strength of their connections, a property called ...
Phys.org / Where did that raindrop come from? Climate model ensemble captures worldwide water isotopes over 45 years
Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are called isotopes. As water evaporates or moves through the atmosphere, the amount of these isotopes changes ...
Phys.org / Why some forests unlock more soil phosphorus: Elevation, soil pH and calcium stand out
Phosphorus is essential for plant growth and ecosystem productivity. In many natural forests, plants rely on soil microbes to release bioavailable phosphorus from organic matter. The PhoD gene, which encodes the key enzyme ...
Phys.org / The radical propulsion needed to catch the solar gravitational lens
Sending a mission to the solar gravitational lens (SGL) is the most effective way of actually directly imaging a potentially habitable planet, as well as its atmosphere, and even possibly some of its cities. But, the SGL ...
