Phys.org / Ancient ground squirrel droppings reveal Arctic's rich evolutionary history
Ground squirrel droppings, preserved for millennia in the Yukon's deep permafrost, have yielded an enormous amount of environmental DNA from dozens of species of plants, insects, microbes and large mammals, offering detailed ...
Phys.org / MeerKAT reveals three electron acceleration sites in one solar flare
Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions during solar flares remain ...
Phys.org / Scientists uncover RNA's hidden role as protein chaperone
Proteins are how cells get work done. They carry out nearly every important cellular task, from ferrying messages to controlling which genes are turned on or off. And in order for proteins to perform their various roles, ...
Phys.org / 'Seismic champagne effect' may explain why fires break out long after earthquakes
Following the devastating urban fire that broke out in Wajima City after Japan's 2024 Noto Peninsula earthquake, investigators struggled to identify a clear ignition source, despite widespread destruction and unusual reports ...
Phys.org / Nature's 'master painters': Study reveals how damselflies break optical barriers to create saturated colors
Scientists at Ben-Gurion University of the Negev (BGU) have uncovered for the first time the "ingenious" biological strategies that allow blue-tailed damselflies to produce strikingly vivid, angle-independent colors. The ...
Phys.org / New dating of Spain's Sala Keimada rock art sanctuary reveals thousands of years of continuous use
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has participated in a study published in the Journal of Archaeological Science: Reports on Sala Keimada, one of the rock art sanctuaries in Cueva Palomera, ...
Phys.org / Chloroplast map reveals 'missing link' in plant growth and solar energy
For decades, science has understood the basics of photosynthesis, the process by which plants turn sunlight into food. However, photosynthesis occurs on uniquely specialized membranes that we have only begun to understand. ...
Phys.org / Hardy ice plant's optical innovation inspires reflective design possibilities
Nature is filled with remarkable visual phenomena created by microscopic surface structures that interact with light in fascinating ways. The iridescent wings of butterflies, the shimmering feathers of birds and the glossy ...
Phys.org / Children's motivation and attitudes towards learning play a key role in academic success, study finds
A major new study led by researchers at Queen Mary University of London has revealed that noncognitive skills—such as motivation, curiosity, academic interest and self-belief—play a key role in translating children's genetic ...
Phys.org / Some drugs 'fail' because of unrealistic testing conditions, scientists discover
A drug once dismissed as ineffective suddenly worked—when scientists tested it under more realistic conditions that mimic the human body. In this surprising new discovery, Northwestern University scientists uncovered a hidden ...
Phys.org / New warning system forecasts wildlife heat risk up to nine months ahead
An international group of scientists led by Josep M. Serra-Diaz, researcher at the Botanical Institute of Barcelona (IBB, CSIC-MCNB), has developed the first global early warning system capable of forecasting when and where ...
Phys.org / Breaking tunnel vision, imaging AI lifts fluorescence image restoration accuracy and speed
Recent years have witnessed great advances in applying deep learning to improve fluorescence microscopy imaging. However, enhancing the fidelity of image restoration networks and improving their robustness under fluorescence ...
