Phys.org / A quick stretch switches this polymer's capacity to transport heat
Most materials have an inherent capacity to handle heat. Plastic, for instance, is typically a poor thermal conductor, whereas materials like marble move heat more efficiently. If you were to place one hand on a marble countertop ...
Phys.org / Capturing the instant of electrical switching to pave the way for faster memory
As artificial intelligence advances, computers demand faster and more efficient memory. The key to ultra-high-speed, low-power semiconductors lies in the "switching" principle—the mechanism by which memory materials turn ...
Phys.org / Nanodevice tugs single proteins to reveal how cells sense force
Physical forces from gravity, muscle contraction, and more have strong impacts on how the cells in our bodies behave. For instance, weight-bearing exercise helps stave off osteoporosis because cells in our bones sense that ...
Phys.org / How the spring thaw influences arsenic levels in lakes
From 1948 to 1953, a gold mine called Giant Mine released about 5 tons of arsenic trioxide per day into the environment around Yellowknife, Northwest Territories, Canada. Emissions declined from the 1950s until the mine closed ...
Medical Xpress / Intermittent fasting cuts Crohn's disease activity by 40% and halves inflammation in randomized clinical trial
A randomized controlled study found that time-restricted feeding—a form of intermittent fasting—significantly reduced symptomatic disease activity and systematic inflammation in adults with Crohn's disease and overweight ...
Medical Xpress / Speed-focused brain training tied to 25% lower dementia risk after 20 years
A simple brain-training exercise could reduce people's risk of developing dementia by 25%, a study said Monday, but with outside researchers expressing caution in interpreting the results.
Medical Xpress / Does a vegetarian upbringing stunt growth? A study of nearly 1.2 million infants suggests not
While the global shift toward plant-based living continues to accelerate, a critical question has lingered for parents and pediatricians: Can a vegan or vegetarian diet support the rapid growth required in the first two years ...
Medical Xpress / AI algorithm enables tracking of brainstem's vital white matter pathways
The signals that drive many of the brain and body's most essential functions—consciousness, sleep, breathing, heart rate and motion—course through bundles of "white matter" fibers in the brainstem, but imaging systems ...
Tech Xplore / Hair-thin silica fiber microphone detects ultrasound from 40 kHz to 1.6 MHz
Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound frequencies beyond the reach of the human ear. Able to withstand temperatures up to 1,000°C, the ...
Medical Xpress / Overlooked group of gut bacteria appears key to good health, global study finds
In a huge global study led by University of Cambridge researchers, a single group of bacteria—named CAG-170—has repeatedly shown up in high numbers in the gut microbiomes of healthy people. CAG-170 is a group of gut bacteria ...
Tech Xplore / Platforms that rank the latest LLMs can be unreliable
A firm that wants to use a large language model (LLM) to summarize sales reports or triage customer inquiries can choose between hundreds of unique LLMs with dozens of model variations, each with slightly different performance. ...
Phys.org / First evidence of a subsurface lava tube on Venus
Volcanic activity is not unique to Earth: traces of volcanic activity, such as lava tubes, have been found on Mars and the moon. Now, the University of Trento has demonstrated the existence of an empty lava tube even in the ...
