Phys.org / Metal hydride molecule trapped with laser light opens path to ultracold hydrogen
Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit ...
Phys.org / A thermodynamic approach to gravity could explain cosmic acceleration without dark energy
Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general relativity. This framework describes gravity as the curvature of spacetime, the invisible four-dimensional ...
Phys.org / Mummified dogs reveal Tiwanaku people buried companions beside homes long before they became status symbols
In the arid landscapes of southern Peru, around 1,100 years ago, someone carefully dug a small pit, laid down a woven mat and placed a young dog within as if sleeping, possibly wrapped in twine. Centuries later, the mummified ...
Phys.org / Scientists find molecular-level evidence for two structures in liquid water
A study published in Nature Physics provides new molecular-level evidence from simulations that liquid water is not a single uniform substance, but a constantly shifting mixture of two distinct microscopic structures.
Tech Xplore / Physical pressure could make EV batteries last twice as long and reduce environmental impact
The key to making longer-lasting electric vehicle batteries may not be specialized materials or new chemistry, but simple physical pressure, according to new research.
Medical Xpress / Billions of doses later: Global review confirms mRNA vaccines are safe, effective and full of promise
A sweeping global review led by researchers at the University of British Columbia has found that mRNA vaccines—now administered billions of times worldwide—are safe and highly effective at preventing infectious diseases like ...
Phys.org / How extreme weather impacts white stork survival in Bulgaria
A comprehensive 15-year study published in Biodiversity Data Journal details the growing threat of extreme weather to white storks (Ciconia ciconia) in Bulgaria. The research, which is part of the topical collection "Restoration ...
Science X / Built-in 'antenna' may help cells sense a healing spark to guide repair after injury
When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current ...
Medical Xpress / Popular GLP-1 weight loss drugs are being misused by people struggling with eating disorders, research reveals
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as Ozempic or Wegovy, have revolutionized type 2 diabetes and weight-loss management, but they have also led to some unfortunate outcomes. A recent study in JAMA ...
Phys.org / A cataclysmic collision in space provides new clues on astronomy's biggest stalemate
Second only to black holes, neutron stars—incredibly dense star remnants—are the densest objects in the universe. When neutron stars collide, they create ripples in the fabric of space and time that we can detect on Earth.
Phys.org / Extreme droughts in the rainforest reduce important feedback between soil and atmosphere, study finds
Isoprene is a volatile organic compound (VOC) that is produced naturally by plants. More than 500 megatonnes of isoprene are emitted each year into Earth's atmosphere, primarily from tropical forests. Soils are recognized ...
Phys.org / One‑step process generates high entropy alloy nanoparticles in milliseconds for catalyst creation
A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published ...
