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 / 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 / 'Periodic table' for AI methods aims to drive innovation
Artificial intelligence is increasingly used to integrate and analyze multiple types of data formats, such as text, images, audio and video. One challenge slowing advances in multimodal AI, however, is the process of choosing ...
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 ...
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 / Water's enigmatic surface: X-ray snapshots reveal atoms and molecules at work
Water is all around us, yet its surface layer—home to chemical reactions that shape life on Earth—is surprisingly hard to study. Experiments at SLAC's X-ray laser are bringing it into focus.
Phys.org / Rare image of Tatooine-like planet is closest to its twin stars yet
In a discovery that's fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns. While obtaining an image of a planet beyond our solar system is already rare, finding ...
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 ...
Phys.org / A new species of tiny orange frog discovered in Brazil's cloud forests
Despite the vast numbers of animal species already identified, the natural world is still capable of springing a few surprises. Deep in the cloud forests of the Serra do Quiriri mountain range in the southern Brazilian Atlantic ...
Phys.org / A healthier sugar substitute: Engineered bacteria yield a sweet solution
From saccharin in the 19th century to stevia and monk fruit in the 21st, researchers and the food industry have long sought a sweetener that delivers the taste of sugar without its drawbacks—excess calories, tooth decay, ...
Phys.org / Plant hormone allows lifelong control of proteins in living animal for first time
Researchers have found a way to control protein levels inside different tissues of a whole, living animal for the first time. The method lets scientists dial protein levels up or down with great precision during the animal's ...
