Phys.org / The persistence of gravitational wave memory
Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they ...
Phys.org / Living tissues are shaped by self-propelled topological defects, biophysicists find
With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects." Published in Physical ...
Phys.org / Symbiotic bacteria in planthoppers break record for smallest non-organelle genome ever found
Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of these symbiotic bacteria ...
Phys.org / The bouba-kiki effect: Baby chicks match sounds to shapes just like humans
When we hear certain sounds, our brains often pair them with specific shapes. For example, most people will associate a sharp-sounding word with a jagged, pointed shape, while a soft, rolling word is linked to something smooth ...
Phys.org / Near-infrared study finds no clear counterpart to mysterious gamma-ray source
Spanish astronomers have conducted a near-infrared study of an ultra-high energy gamma-ray source designated LHAASO J2108+5157. The new study, published February 11 on the arXiv preprint server, tries to unravel the mysterious ...
Phys.org / Quantum entanglement could link distant telescopes for sharper images
To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, entails comparing the ...
Phys.org / Evidence points to early goat and sheep dairy consumption in Neolithic Iran
Approximately 9,000 years ago, human communities in Southwest Asia underwent a dramatic transformation, known as the Neolithic revolution. This period was marked by pronounced changes in how they lived and sourced food, with ...
Phys.org / Atom-thin electronics withstand space radiation, potentially surviving for centuries in orbit
Atom-thick layers of molybdenum disulfide are ideally suited for radiation-resistant spacecraft electronics, researchers in China have confirmed. In a study published in Nature, Peng Zhou and colleagues at Fudan University ...
Phys.org / How early farming unintentionally bred highly competitive 'warrior' wheat
An evolutionary "arms race" for light and space led to the early domestication of wheat, according to new research that could offer fresh insights into crop design. The study led by Dr. Yixiang Shan and Professor Colin Osborne, ...
Phys.org / How massive lava fields formed in the Pacific Northwest
Volcanic eruptions are significant geologic hazards. Underwater volcanoes are challenging to study, yet they play an integral role in marine geology and may cause destructive tsunamis that can threaten coastal communities.
Phys.org / 'All-in-one,' single-atom could power both sides of water splitting
Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. Green hydrogen is produced ...
Phys.org / Cleaner fish show intelligence typical of mammals
Researchers at Osaka Metropolitan University in Japan have discovered a previously undiscovered behavior in cleaner wrasse (Labroides dimidiatus). When presented with a mirror, the tiny fish not only recognized themselves, ...
