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 / Sequencing genomes from museum collections could transform scientific inquiry
Natural history collections around the world collectively hold more than 1 billion specimens, spanning a wide variety of times and places. These include species that are extinct or come from areas now transformed beyond recognition, ...
Phys.org / How migrating cells build their leading edge: Master regulator may resolve long-standing debate
The ability of cells to move and change position is essential for various processes in our bodies. Immune cells move to sites of action, epithelial cells migrate during wound closure, and neurons extend their axons for signal ...
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. ...
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 / Lemur uses opera singer's trick to belt out forest songs
We are often left open-mouthed in awe as an opera singer hits a soaring top note. Now, researchers at the University of Warwick have found that the indri, the world's only known singing lemur, appears to use a strikingly ...
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 ...
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 / 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 / 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 / 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 ...
