Phys.org / AI-powered barcode unmasks 'zombie cells' in aging tissue
As we age, some of the cells in our body enter a state of senescence, in which they stop dividing but do not die. Those senescent cells can contribute to age-related disorders such as cancer, tissue degeneration and inflammatory ...
Phys.org / Environmental science takes an average of seven years to influence international policy, study finds
A new study led by the University of Alicante (UA) and the Mediterranean Center for Environmental Studies (CEAM) analyzes the barriers separating scientific knowledge from environmental policy and its effective implementation. ...
Phys.org / Quantum communication protocol enables three users to establish a shared secure key
Quantum key distribution allows two users to establish secret keys whose security is grounded in the laws of quantum mechanics. Extending this capability to multiple users is an essential step toward quantum networks that ...
Dialog / Photonic Legos of functional 3D thin-films unlock high-performance heterogeneous photonic integration
Photonic integrated circuits route information with optical signals instead of relying only on electrical currents. Silicon (Si) and silicon nitride (SiNx) are excellent photonic platforms for waveguides, but they cannot ...
Phys.org / X-ray light is like guitar music, with frequencies sliding continuously between harmonics
Ultrashort laser pulses can be used to generate X-rays. Normally, however, only certain specific frequencies are produced. A team from TU Wien and the University of California San Diego has developed a method that makes it ...
Phys.org / Tiny molecular scissors reveal how crystals bend without breaking
Crystals are usually thought of as rigid and brittle. Yet some molecular crystals can bend, jump, twist or even change shape when exposed to light. Understanding how tiny molecular movements inside an ordered crystal can ...
Phys.org / Flies, mice and humans share a walking pattern despite radically different bodies
Flies, mice and humans move in different ways because of their very different physiques, but their movements follow a common pattern— joints farther from the center of the body move faster than those closer to the body. This ...
Phys.org / Genes that help flatworms regenerate their brains revealed
The human brain is terrible at healing itself from injury or disease. But some animals can harness their own cellular abilities not only to repair injuries but also to regrow their brains entirely. Researchers from the University ...
Phys.org / African smoke brightens clouds, but weather patterns offset its cooling effect
Smoke from African agricultural fires brightens clouds over the southeast Atlantic—but new research from scientists at the University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science shows that the same ...
Phys.org / Longitudinal survey finds little evidence that social tech predicts life satisfaction in adults
Social technologies, digital tools that allow people to communicate and share content with each other online, have become a central way of communicating for many people worldwide. Yet the possible effects of these technologies ...
Phys.org / Tiny beach-dwelling crustaceans are big-time sand movers, shaping the California coast
Stand on the damp sand on a California beach and chances are you're standing on top of an active earthworks site. Sand hoppers (Megalorchestia spp.), the tiny, shrimp-like creatures commonly found eating away at kelp on the ...
Phys.org / 'Rusty treasure' find revealed as Europe's largest assemblage of prehistoric iron bars
Analysis of a "rusty treasure" excavated during industrial gravel extraction at Deinham, Austria, reveals it is the largest mass find of prehistoric iron bars in Europe, pointing to iron production and trade during the Iron ...
