Phys.org / The growing threat of vast ravines swallowing streets and homes
Deep, gigantic cracks in the Earth known as gullies are tearing through African cities, swallowing up houses and streets, destroying infrastructure and displacing tens of thousands of people. Left unchecked, this new geological ...
Phys.org / Mutations driving evolution are informed by the genome, not random, study suggests
A study published in the Proceedings of the National Academy of Sciences by scientists from Israel and Ghana shows that an evolutionarily significant mutation in the human APOL1 gene arises not randomly but more frequently ...
Phys.org / New modeling indicates 100-year-old geological theory on the Himalayas may have been wrong all along
For the last century, Émile Argand's theory on the formation and geological support system of the massive Himalayan mountain range has remained the predominant explanation widely accepted among geologists. This theory states ...
Phys.org / Deep learning method enables efficient Boltzmann distribution sampling across a continuous temperature range
A research team has developed a novel direct sampling method based on deep generative models. Their method enables efficient sampling of the Boltzmann distribution across a continuous temperature range. The findings have ...
Phys.org / DNA-based neural network learns from examples to solve problems
Neural networks are computing systems designed to mimic both the structure and function of the human brain. Caltech researchers have been developing a neural network made out of strands of DNA instead of electronic parts ...
Phys.org / Automated tool enables rapid, large-scale profiling of disease-linked RNA modifications
Researchers have developed a powerful tool capable of scanning thousands of biological samples to detect transfer ribonucleic acid (tRNA) modifications—tiny chemical changes to RNA molecules that help control how cells ...
Phys.org / Quantum emitter discovery in diamonds enables a new type of coupling
Researchers at The City College of New York have shown how a quantum emitter, the nitrogen-vacancy (NV) center in diamond, interacts in unexpected ways with a specially engineered photonic structure when moved around with ...
Phys.org / How the palmette motif shifted from elite status symbol to royal emblem in Iron Age Judah
In a study published by Reli Avisar in the Levant journal, the author examines the symbol of the palmette and how its meaning changed together with the local political and social atmosphere.
Phys.org / A new scale of biology: Massive datasets are aiding in the fight against superbugs
Artificial intelligence relies on machine learning algorithms trained on massive datasets to make predictions—think of how ChatGPT learned language by gorging on the internet. In biology, however, scientists face a frustrating ...
Phys.org / Nutrient-enriched seagrass can store more carbon, but too much nutrition—especially nitrogen—can be its undoing
Seagrass has the potential to be one of the world's most effective sponges at soaking up and storing carbon, but we don't yet know how nutrient pollution affects its ability to sequester carbon.
Phys.org / New biocatalytic method can generate a library of novel molecules for drug discovery
Using reprogrammed biocatalysts, researchers are pushing the boundaries of enzymatic synthesis with a method that opens the door to a diverse array of valuable compounds. Reporting in the journal Science, UC Santa Barbara ...
Phys.org / Webb reveals warm space dust in far-off Makani galaxy's circumgalactic medium
In a distant galaxy called Makani, particles of dust were warmed by the light of newborn stars before being flung out into space by a massive starburst-driven wind. Over the course of 100 million years, the dust traveled ...
