Medical Xpress / Better sleep could reduce anxiety in later life
As humans grow older, their emotional stability and sleep patterns can change significantly. For instance, some past studies have found that many older adults find it harder to manage negative emotions, experience higher ...
Tech Xplore / Graphene-based 'artificial skin' brings human-like touch closer to robots
Robots are becoming increasingly capable in vision and movement, yet touch remains one of their major weaknesses. Now, researchers have developed a miniature tactile sensor that could give robots something much closer to ...
Phys.org / Study finds 77% of US national parks are highly vulnerable to climate change
National parks in the United States represent a treasure trove of natural, historical, and recreational landscapes, but their health is at risk. A comprehensive new study on the climate-change vulnerability of national parks, ...
Phys.org / How evolution shapes color diversity in coral reef fish
Why does a Caribbean angelfish sometimes resemble its Indo-Pacific cousin, even though they have never lived in the same ocean? Why do coral reefs harbor such a wide range of stripes, spots and patterns? A study conducted ...
Dialog / Chemically tuning nanographene into topological spin chains and why the ends matter
When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic building blocks in a one-dimensional ...
Phys.org / The Maya engineering paradox: Masters of water, prisoners of mercury
Under the supervision of Université de Montréal archaeology professor Christina Halperin, Ph.D. student Jean Tremblay spent six years, from 2018 to 2024, studying how the Mayan city of Ucanal managed its drinking water. ...
Phys.org / Polymers that crawl like worms: How materials can develop direction without being told where to go
Researchers at the University of Vienna have uncovered a surprising phenomenon: polymer chains with segments that simply fluctuate at different intensities can spontaneously develop directional, persistent motion when densely ...
Medical Xpress / Former American football players show higher risk of later-life memory and mental health issues
American football is a high-octane contact sport in which repetitive head impacts (RHI) are a common sight. Researchers investigated the link between playing football and brain health, memory, and mental well-being later ...
Tech Xplore / Can thermal noise train a computer? A new framework points to low-power AI
What if the thermal noise that hinders the efficiency of both classical and quantum computers could, instead, be used as a power source? What if computers could make use of the noise instead of suppressing or overcoming it? ...
Phys.org / Ocean currents drive disease spread between oyster reefs: Research identifies restoration sites at risk
The European flat oyster (Ostrea edulis) was once widespread in the North Sea. However, overfishing, habitat destruction and infectious diseases pushed the species to the brink of extinction in some regions nearly one hundred ...
Tech Xplore / Listening to the body's quietest, yet most dynamic movements with a wearable sensor
The human body continuously generates a rich spectrum of vibrations—often without us ever noticing. Everyday unconscious activities such as breathing, speaking, and swallowing all produce subtle yet distinct mechanical ...
Medical Xpress / Trial suggests GLP-1 combo therapy cuts fat while preserving muscle in obesity
A recent research study found that a combination of the GLP-1 receptor agonist semaglutide and bimagrumab, an antibody that blocks activin signaling pathways, results in greater weight loss while also preserving lean mass, ...
