Phys.org / Continuous stirring made early life-like RNA systems more extinction-prone, experiment shows
Recent research showed that an artificially constructed self-replicating RNA system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental conditions.
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 / 'Flawless on the outside, flipped within': Detecting hidden defects in 2D dielectrics with light
A material may appear flawless on the surface yet fail to function properly. The cause lies in structural defects hidden within two-dimensional thin films, which are considered key materials for next-generation semiconductor ...
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 / 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 / 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 / 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 / Volcanic eruptions linked to rising famine risk across China's history
Large volcanic eruptions may have played a bigger role in triggering historical famines across China than previously understood, according to a new study that traced links between eruptions, climate disruption, and food shortages ...
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 / 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 / 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. ...
Dialog / Sweet basil carbon dots show potential for sustainable agriculture
What if a common herb found in the kitchen could help farmers grow healthier crops? As the global population grows and agriculture faces increasing environmental challenges, scientists are searching for innovative ways to ...
