Phys.org / Gold nanoparticles unlock vibrant structural colors across the visible spectrum
Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues ...
Phys.org / Quantum circuits help AI overcome memory limitations with minimal new parameters
For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.
Phys.org / Terahertz biophotonics: Understanding the path towards practical applications for biological imaging
Biophotonics is a multidisciplinary field that involves the development and application of light-based technologies to study, monitor and treat biological systems. The ability to directly image cells and molecules has led ...
Phys.org / First nonrepeating biological clock discovered in C. elegans guides growth
Imagine a train parked at the station. Passengers climb aboard and find their seats. Conductors move up and down the aisles, checking tickets. But there's a problem—the engineer's watch is broken. As a result, the doors never ...
Phys.org / Hidden protein switch controls photosynthesis as light conditions change
Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. The results, published ...
Phys.org / Machine learning uncovers 1,750 quakes tracing 250-kilometer edge of Alaska microplate
Thousands of small earthquakes, detected for the first time by a machine-learning process, reveal the distinct, razor-sharp edge of the Yakutat microplate as it subducts beneath the North American plate.
Phys.org / Predictive surrogates could cut quantum computing measurement overhead by more than 99.97%
Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical computers on some tasks. Despite their potential, the use of these systems remains very ...
Phys.org / Medieval pandemic left a hidden legacy in Europe's oldest trees
A new study published in the Proceedings of the National Academy of Sciences demonstrates how radiocarbon dating can reveal the maximum lifespan of Mediterranean hardwoods, uncovering hidden links between human history and ...
Phys.org / MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk
Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational ...
Phys.org / 120,000-year-old European fallow deer—tracing the loss of genetic diversity
European fallow deer have faced a dramatic loss of genetic diversity since the last interglacial period. This was revealed by 120,000-year-old fossils from central Germany's Neumark-Nord site in Saxony-Anhalt, analyzed by ...
Phys.org / Mount Etna eruptions reveal carbon dioxide and water can trigger separate explosive paths
The plumbing systems of volcanoes are vast and complex. But they aren't consistent, even in the same volcano. A Cornell-led collaboration found very different mechanisms behind two historic eruptions of Mount Etna in Italy. ...
Phys.org / Infrastructure for African mines destroying forests at 34 times the rate of the mines themselves
Industrial-scale mining in Africa to support global supply chains is leading to unprecedented deforestation across the continent, with 34 hectares of forest removed for every single hectare of active mine site.
