Phys.org / For thousands of years, solar eclipses have been associated with the fate of rulers
The moon crossed the sun's path on February 17, causing what is known as an annular solar eclipse. The sun was not covered completely, but the moon blocked enough of its light to leave a fiery ring. Unless you're deep in ...
Phys.org / Endangered Kenyan antelopes rescued after being stranded at Palm Beach airport
When Paul Reillo learned the endangered mountain bongo antelopes that he had cared for since birth were stranded in a cargo plane on an airport tarmac ahead of their journey to a new home in Kenya, he took matters into his ...
Phys.org / Call me invasive: New evidence confirms the status of the giant Asian mantis in Europe
In the realm of entomology, few creatures command as much fascination as the mantis. Throughout history, these striking insects have been deeply woven into local myths and legends, sometimes respected as mystical soothsayers ...
Phys.org / Quantum trembling: Why there are no truly flat molecules
Traditional chemistry textbooks present a tidy picture: Atoms in molecules occupy fixed positions, connected by rigid rods. A molecule such as formic acid (methanoic acid, HCOOH) is imagined as two-dimensional—flat as a ...
Phys.org / New microscopy technique lets scientists see cells in unprecedented detail and color
Scientists have developed a new imaging technique that uses a novel contrast mechanism in bioimaging to merge the strengths of two powerful microscopy methods, allowing researchers to see both the intricate architecture of ...
Tech Xplore / AI chatbots provide less-accurate information to vulnerable users, study shows
Large language models (LLMs) have been championed as tools that could democratize access to information worldwide, offering knowledge in a user-friendly interface regardless of a person's background or location. However, ...
Tech Xplore / New chip-fabrication method creates 'twin' fingerprints for direct authentication
Just like each person has unique fingerprints, every CMOS chip has a distinctive "fingerprint" caused by tiny, random manufacturing variations. Engineers can leverage this unforgeable ID for authentication, to safeguard a ...
Phys.org / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...
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 / Phonon lasers unlock ultrabroadband acoustic frequency combs
Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency combs, which consist of equally ...
Medical Xpress / Astrocytes, not just neurons, found to drive fear memory signals in the amygdala
Picture a star-shaped cell in the brain, stretching its spindly arms out to cradle the neurons around it. That's an astrocyte, and for a long time, scientists thought its job was caretaking the brain, gluing together neurons, ...
Phys.org / Birds change altitude to survive epic journeys across deserts and seas
Every year, billions of birds undertake extraordinary migrations, crossing vast deserts and open seas with no place to stop, feed, or rest. A new international study published in iScience by a consortium of researchers from ...
