Phys.org / How a broken DNA repair tool accelerates aging
Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal metabolic processes or external stressors such as radiation or chemical substances. To counteract this, ...
Phys.org / Record-breaking photons at telecom wavelengths—on demand
A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand ...
Phys.org / Quantum mechanical effects help overcome a fundamental limitation of optical microscopy
Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of quantum mechanical effects, they succeeded for the first time in performing optical measurements with ...
Phys.org / AI enables a who's who of brown bears in Alaska
A team of scientists from EPFL and Alaska Pacific University has developed an AI program that can recognize individual bears in the wild, despite the substantial changes that occur in their appearance over the summer season. ...
Phys.org / 2D discrete time crystals realized on a quantum computer for the first time
Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist in increases—even more so in quantum systems. While discrete time crystals (DTCs) had been previously ...
Phys.org / The first headbutting paravian: Bird-like dinosaur likely used thick skull to win over mates
Whether it's digging up weathered bones from a paleontological site or reexamining forgotten trays in museum and university collections, the study of dinosaurs still throws up something new.
Phys.org / Liquid-repellent particle coating enables near-frictionless motion of pico- to nanoliter droplets
The precise control of tiny droplets on surfaces is essential for advanced manufacturing, pharmaceuticals, and next‐generation lab‐on‐a‐chip diagnostics. However, once droplet volume reaches pico- and nanoliter scales, ...
Phys.org / Beyond the eye of the beholder: Mathematically defining attributes essential to color perception
Research on the perception of color differences is helping resolve a century-old understanding of color developed by Erwin Schrödinger. Los Alamos scientist Roxana Bujack led a team that used geometry to mathematically define ...
Medical Xpress / The brain's protein cleanup process may play a role in dementia
Microglia are the brain's immune cells that clean out debris, such as damaged proteins and old cell parts, to keep the organ healthy. But the very properties that make these cells so useful might also be a driving factor ...
Phys.org / Beamline measurements of unstable ruthenium nuclei confirm advanced nuclear models
A novel apparatus at the U.S. Department of Energy's (DOE) Argonne National Laboratory has made extremely precise measurements of unstable ruthenium nuclei. The measurements are a significant milestone in nuclear physics ...
Phys.org / Scientists teach microorganisms to build molecules with light
Researchers are continually looking for new ways to hack the cellular machinery of microbes like yeast and bacteria to make products that are useful for humans and society. In a new proof-of-concept study, a team from the ...
Phys.org / Mapping cell development with mathematics-informed machine learning
The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
