Phys.org / Immune cells selectively pull DNA from dying nuclei, revealing a process dubbed nucleocytosis
Over the years, cell biology has built a detailed picture of how cells compartmentalize their internal functions. Central to this organization is the nucleus, which houses the genetic material and is separated from the cytoplasm ...
Phys.org / Vertebrate paleontology has a numbers problem. Computer vision can help
How many fossils does it take to accurately train an image-based AI algorithm? According to a new study co-authored by Bruce MacFadden, UF Distinguished Professor Emeritus and retired curator of vertebrate paleontology at ...
Phys.org / Nano-cage removes up to 98% of PFAS in tap water tests
Contamination of ground, surface and drinking water by perfluoroalkyl and polyfluoroalkyl substances (PFAS) affects millions of people worldwide. A promising new method developed by Flinders University scientists paves the ...
Phys.org / Webb examines 'Exposed Cranium' nebula
Two heads are better than one in the latest images from NASA's James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that ...
Phys.org / A robust new telecom qubit identified in silicon
Quantum technologies are anticipated to transform computing, communication, and sensing by harnessing the unusual behavior of matter at the atomic scale. Translating quantum's promise into practical devices will require physical ...
Phys.org / Humanity's oldest geometries, engraved on ostrich eggs
At several archaeological sites in southern Africa, hundreds of highly unusual fragments of ostrich eggs have been found. Dating back more than 60,000 years, the shells were engraved by groups of Homo sapiens who lived in ...
Phys.org / Hidden architecture inside cellular droplets reveals new targets for cancer and neurodegeneration
Cells rely on biomolecular condensates to coordinate essential biological processes without surrounding membranes. These droplet-like dynamic assemblies control the way in which DNA is turned into proteins, help clear cellular ...
Phys.org / Iron nanoparticle eliminates tuberculosis in mice and may pave the way for new treatments
An iron-based compound encapsulated in lipid nanoparticles completely eliminated tuberculosis in the lungs of mice after 30 days of treatment, according to a study by the Tuberculosis Research Laboratory at the Araraquara ...
Phys.org / Farming on the moon or Mars? How recycled sewage could turn regolith into crop soil
Dining on the moon or Mars might seem like a fantasy reserved for science fiction, but researchers are investigating how it could become a reality. Their efforts to recycle plant and human waste into a fertilizer material—turning ...
Phys.org / A world first at the microscopic scale: Metamaterials that can shrink and expand on their own
Leiden physicists Daniela Kraft and Julio Melio have created soft structures that can take on different shapes without any external drive in their lab. They present their research on microscale metamaterials in Nature—a ...
Phys.org / The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses
Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or a cycle of intermittent ...
Phys.org / Land plants began reshaping Earth 455 million years ago, scientists discover
Pinpointing when early land plants colonized terrestrial environments and began influencing Earth's systems is a core question in the evolution of the Earth system. A research team led by Prof. Zhao Mingyu at the Institute ...
