Tech Xplore / Beyond mimicry: Fiber-type artificial muscles outperform biological muscles
Biological muscles act as flexible actuators, generating force naturally and with an impressive range of motion. Unsurprisingly, scientists and engineers have been striving to build artificial muscles that mimic these abilities. ...
Tech Xplore / A two-stage decision-making framework for lithium governance in Latin America
The evolving global order, intense geopolitical competition, and anxiety over supply chain vulnerabilities in this century have led to urgent concerns over supply chain resilience as well as national security. Amidst these ...
Phys.org / Comet 3I/ATLAS displays greenish hue in new Gemini North telescope images
Gemini North captured new images of Comet 3I/ATLAS after it reemerged from behind the sun on its path out of the solar system. The data were collected during a Shadow the Scientists session—a unique outreach initiative ...
Phys.org / Growth strategy enables coherent quantum transport in single-layer MoS₂ semiconductors
Two-dimensional (2D) semiconductors are thin materials (i.e., one-atom thick) with advantageous electronic properties. These materials have proved to be promising for the development of thinner, highly performing electronics, ...
Tech Xplore / Exploring how negative electricity prices influence consumer behavior
In some cases, and for limited periods, energy suppliers can generate more energy than is needed, which can lead to so-called negative prices. This is typically observed in wind and solar energy, for instance, during particularly ...
Medical Xpress / Tanning beds mutate skin cells far beyond the reach of ordinary sunlight, study shows
Tanning bed use is tied to almost a three-fold increase in melanoma risk, and for the first time, scientists have shown how these devices cause melanoma-linked DNA damage across nearly the entire skin surface, reports a new ...
Phys.org / Unique bond identified as key to viral infection speed
Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State reveals a deliberate imbalance in their shape that ...
Phys.org / A new medium for canine stem cells that doesn't contain any human components
Canine induced pluripotent stem (iPS) cells possess the ability to differentiate into any type of cell, making them a useful tool for investigating common canine diseases and disease states, including those of humans.
Phys.org / Smarter tools for peering into the microscopic world developed
The microscopic organisms that fill our bodies, soils, oceans and atmosphere play essential roles in human health and the planet's ecosystems. Yet even with modern DNA sequencing, figuring out what these microbes are and ...
Tech Xplore / More brines could be mined for lithium with counterintuitive method
Lithium could be selectively extracted from "low quality" brines using a surprising mechanism discovered at the University of Michigan. The technology could help make brine lakes rich in magnesium a more sustainable source ...
Medical Xpress / How hippocampal synapses adjust their proteins to specialize their function
A research team led by Dr. Àlex Bayés, Head of the Molecular Physiology of the Synapse Group at the Institut de Recerca Sant Pau (IR Sant Pau), has achieved what for decades had been an elusive goal: obtaining a precise, ...
Phys.org / Feedback loops from oil fields accelerate Arctic warming and other atmospheric changes, study shows
The climate is changing and nowhere is it changing faster than at Earth's poles. Researchers at Penn State have painted a comprehensive picture of the chemical processes taking place in the Arctic and found that there are ...
