Phys.org / Stress-reduction molecule has potential to treat aging and metabolic disorders
University of Queensland researchers say the discovery of a new stress reduction role for a naturally occurring molecule in the body could lead to new drugs and treatment for metabolic disorders and aging.
Phys.org / Expanding existing mines poses overlooked long-term environmental and social risks
Mining companies worldwide are expanding mineral extraction at existing mines, as the rate of opening new sites slows, to meet global demand driven mainly by the need for clean energy infrastructure.
Phys.org / 3D-printed surfaces help atoms play ball to improve quantum sensors
Scientists have created 3D printed surfaces featuring intricate textures that can be used to bounce unwanted gas particles away from quantum sensors, allowing useful particles like atoms to be delivered more efficiently, ...
Phys.org / Tuning color through molecular stacking: A new strategy for smarter pressure sensors
Piezofluorochromism, the phenomenon of materials reversibly changing their fluorescent color when pressure is applied, is used to create the pressure sensors used in automotive and medical industries. By monitoring color ...
Phys.org / Living walls boost biodiversity by providing safe spaces for urban wildlife
Living walls—structures housing flowers and plants fitted to the outside of new and old buildings—can significantly enhance the biodiversity within urban environments, a new study has shown.
Phys.org / Humans use local dialects to communicate with honeyguide birds, research shows
Researchers from the University of Cape Town (UCT), working with international collaborators, have shown that people in northern Mozambique use regionally distinct "dialects" when communicating with honeyguide birds, revealing ...
Phys.org / Evidence of 'lightning-fast' evolution found after Chicxulub impact
The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate change. But new research shows that it also ...
Phys.org / DNA nanodevices reveal acidic nanolayer on lysosome surfaces in live cells
Lysosomes are membrane-bound organelles whose acidic lumen (pH 4.5–5.0) is required for degradation. This luminal acidity is known to regulate cytosolic-side functions such as membrane fusion/fission, movement, and membrane-contact ...
Phys.org / The hidden microbial communities that shape health in space
Microorganisms live in biofilms—the equivalent of microbial "cities"—everywhere on Earth. These city-like structures protect and house microbial communities and play essential roles in enabling human and plant health ...
Phys.org / Unified framework sorts spacetime fluctuations for quantum-gravity experiments
A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear in many attempts to ...
Phys.org / Massive black hole mystery unlocked by researchers
It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today ...
Phys.org / Bionic LiDAR system achieves beyond-retinal resolution through adaptive focusing
In a recent study, researchers from China have developed a chip-scale LiDAR system that mimics the human eye's foveation by dynamically concentrating high-resolution sensing on regions of interest (ROIs) while maintaining ...
