Medical Xpress / Stress before conception may reprogram sperm and boost male offspring growth
Research from the University of Colorado Anschutz suggests that stress experienced by a father before conception may influence an offspring's growth by altering small molecular signals in sperm. The study, published in iScience, ...
Medical Xpress / Memory decline after menopause linked to loss of estrogen production in brain tissue
A largely overlooked space between cells in women's brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study.
Phys.org / DNA reveals hidden UV defense network that dissipates energy in femtoseconds
New details of how DNA protects itself from harmful ultraviolet (UV) radiation show a hidden network of ultrafast molecular reactions that help prevent damage before it can trigger mutations that might lead to cancer, according ...
Phys.org / Fire salamanders reveal hidden turquoise glow when exposed to UV radiation
An international research team has discovered that the fire salamander (Salamandra salamandra) is biofluorescent. A study published in the journal Royal Society Open Science shows that the salamander reflects turquoise light ...
Medical Xpress / AI uncovers why squeezed tumors grow slower under physical pressure
Researchers have solved a long-standing mystery about why physical forces slow cancer growth—and the answer could reshape how the disease is treated. A multidisciplinary team from University of Galway, CÚRAM, the Taighde ...
Phys.org / Stretching and squeezing drive the timing of glacial meltwater release
As meltwater drains through and beneath a glacier, it can alter how the ice flows and whether it breaks apart. Meltwater can also cause feedback that leads to more ice loss. Understanding when and how glacial meltwater drains ...
Phys.org / Homeless encampment sweeps spiked after Supreme Court decision
Officials in Oakland sharply increased the number of homeless encampments they cleared in the months after the 2024 U.S. Supreme Court decision made it easier for municipalities nationwide to do so, new research from UC Berkeley ...
Phys.org / Southeast Asia's changing landscape is fueling a deadly air crisis that costs billions
Changes in land-use across Southeast Asia over the past 15 years are worsening air quality and contributing to thousands of excess deaths each year, according to a study led by researchers from Nanyang Technological University, ...
Tech Xplore / Physics-aware AI generates more realistic sounds by estimating mass and velocity from video
When people watch a scene in the film "Jurassic Park" where a giant dinosaur walks toward them, they naturally imagine a heavy, rumbling sound, as if the ground were shaking. This is because humans predict sound by considering ...
Phys.org / Ice may release more iron than climate models predict
Most people think of ice as frozen and lifeless, but research at Umeå University shows the opposite. A new study published in the Proceedings of the National Academy of Sciences demonstrates that ice actively speeds up the ...
Tech Xplore / New smart material could let windows store solar power and tint on demand
The growing demand for sustainable and energy-efficient technologies has increased interest in smart materials that can perform more than one function at the same time. In his doctoral dissertation, MSc Sachin Kochrekar developed ...
Phys.org / It looks like rice's own defense, but this fungal trick turns a lifesaving response into a crop-killing weapon
For about half the global population, rice is the staple food. Yet every year, a fungal disease—rice blast—destroys harvests that could feed 60 million people. Researchers at the Karlsruhe Institute of Technology (KIT) have ...
