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 / 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 / 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 / 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 / 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 / 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 / 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 / Scientists reveal best- and worst-case scenarios for a warming Antarctica
The climate crisis is warming Antarctica fast, with potentially disastrous consequences. Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes ...
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 / 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, ...
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 / 3D method can accurately measure gravity in wide binary stars, as demonstrated by pilot study
Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of gravity in the low acceleration ...
