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 / Ancient diets reveal surprising survival strategies in prehistoric Poland
An international team of archaeologists and scientists has reconstructed the diets of prehistoric communities from north-central Poland, shedding new light on how people adapted to changing environments and shifting social ...
Phys.org / Hair-like rhizoids in liverworts transport phosphorus, shedding light on evolution of roots
Liverwort uses hair-like rhizoids to collect phosphorus from its surroundings and deliver it to where it is needed. This Kobe University discovery sheds light on the evolution of one of the most essential features of land ...
Phys.org / Plants stay neatly patterned as they grow, and PLETHORA proteins may explain why
How do plants achieve their remarkably regular arrangement of leaves and flowers? And why does this pattern remain so stable, even as plants grow and respond to their environment? Researchers at Wageningen University & Research ...
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 / 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 / Lab tests investigate how house fire emissions differ from forest fires
Wildfires have increased in frequency and severity over the past few decades. More fires are burning at the wildland-urban interface (WUI), where homes and other buildings meet the natural landscape—but our understanding ...
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 / How a 3D-printed synthetic sea lion pelvis enhances veterinary capabilities to counter ongoing beaching
Scores of sea lions continue to beach themselves along the Southern California coastline, stricken with sickness. Toxic algae blooms are to blame, though a mechanical engineering innovation could shift the tide in favor of ...
Phys.org / Boat traffic alters marine megafauna behavior, stress and population trends, global analysis finds
A new study provides a comprehensive global synthesis of how vessel traffic affects large marine wildlife, including whales, dolphins, seals, manatees, sea turtles, sharks and rays. The study, "Charting the Course for Management: ...
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 / 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 ...
