Phys.org / Reading hidden topology in light, even when energy leaks away
When I explain topology to students, I start with a knot in a rope. You can stretch it, twist it or shake it, but the knot stays until you cut the rope. Physicists have found that some materials and devices carry similar ...
Phys.org / Cooper pairs found above superconducting critical temperature in pair density waves
Physicists with the University of Illinois Urbana-Champaign's Grainger College of Engineering have identified a new form of superconducting behavior. Experiments on the metal uranium ditelluride reveal that Cooper pairs, ...
Phys.org / Q&A: How will quantum computers change society?
Once called a "pipe dream," quantum computers are now approaching practical use. Companies and research institutes around the world are in fierce competition to develop this technology, which has the potential to rapidly ...
Phys.org / Webb provides crash course on planet-shattering collisions
In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced ...
Phys.org / AI method predicts retention times of small molecules more reliably
Whether in drug discovery, environmental analysis or metabolomics: anyone analyzing complex biological samples often needs to identify the small molecules they contain. Researchers at Friedrich Schiller University Jena, in ...
Phys.org / How cities and extreme rainfall shape each other
New research brings together recent advances in urban hydrology, boundary-layer meteorology, extreme precipitation and flood-risk research and proposes a new framework for understanding how cities and extreme rainfall interact ...
Phys.org / Crystals thinner than human hair can move or partly dissolve when exposed to chloroform
Many of the common materials we encounter in our daily lives are crystalline, including ice, salt and sugar. The crystal structures of some solids are formed from molecules arranged in simple geometric patterns, and these ...
Tech Xplore / Scientists monitor the 'brittleness' of cathode in a working lithium battery in real time
Researchers from the Laboratory of Hierarchically Structured Materials at the Skoltech Engineering Center and the Center for Energy Technologies, together with colleagues from Lomonosov Moscow State University and the IDEA ...
Phys.org / Sex-like DNA exchange in starving bacteria occurs over 100 times more often than spontaneous mutations
How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity to transfer and incorporate DNA, accelerating genetic reshuffling. ...
Tech Xplore / Mining without digging: Liquid metal tin turns desalination brine into a magnesium resource
Water scarcity is becoming increasingly serious worldwide as population growth and climate change increase demand for freshwater. Seawater desalination is therefore attracting growing attention, especially in arid regions. ...
Phys.org / Chlamydia packs DNA with lipids, revealing possible target for blocking infection
The bacterium Chlamydia trachomatis is one of the most common causes of sexually transmitted infections worldwide. Biologically, it is regarded as a highly specialized "nutrient thief": Because chlamydia have lost the ability ...
Tech Xplore / Prussian blue improves perovskite solar performance from small cells to larger modules
Perovskite solar cells (PSCs) are a promising next-generation photovoltaic technology that can achieve high power conversion efficiencies. However, their performance and long-term stability are limited by problems that arise ...
