Phys.org / The dinosaurs that forgot how to fly
A new study led by a researcher from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv University examined dinosaur fossils preserved with their feathers and found that these dinosaurs had lost ...
Tech Xplore / Harry Potter-style 'moving invisibility cloak' technology developed
What do Harry Potter's invisibility cloak and stealth fighter jets that evade radar have in common? They both make objects invisible despite their physical presence. Building upon this concept, a research team has taken it ...
Phys.org / Video: Lunar impact flash detected on the moon by Armagh Observatory and Planetarium
On 12 December 2025 at 03:09:36 UTC, astronomers at the Armagh Observatory and Planetarium (AOP) have captured what is believed to be the first video recording of a lunar impact flash in Ireland, and the second recorded from ...
Phys.org / Why do wombats have square poop?
Most people have a preferred way of communication—phone, text, email—but bare-nosed wombats have an unusual way of relaying information.
Phys.org / Rare, deep-sea encounter: Scientists observe 'extraordinary' seven-arm octopus
Almost a half-mile below the surface of Monterey Bay, California, scientists have recorded rare footage of a seven-arm octopus— only the fourth time the same research team has spotted the species in about four decades.
Tech Xplore / Researchers reveal bias in a widely used measure of algorithm performance
When scientists test algorithms that sort or classify data, they often turn to a trusted tool called Normalized Mutual Information (or NMI) to measure how well an algorithm's output matches reality. But according to new research, ...
Phys.org / Vital intertwining: Blood parasite's chainmail-like DNA structure could inspire next-generation materials
As tough as medieval chainmail armor and as soft as a contact lens. This material is not taken from science fiction, it is a natural structure made of thousands of DNA circles interlinked with each other. Studying it can ...
Phys.org / Five family Christmas games that reveal how we think, communicate and connect
For many families at Christmas, the one time of year when everyone finally ends up in the same room, suggesting a game is often the best strategic move for a fun evening. At its best, this sparks an hour of genuine connection. ...
Tech Xplore / New interface engineering strategy developed for efficient and stable back-contact solar cells
As the demand for renewable energy grows, scientists are developing new types of solar cells that are both highly efficient and scalable. The back-contact perovskite solar cell (BC-PSC) is one such innovative architecture, ...
Tech Xplore / Assumptions about battery failure challenged: Single-crystal materials require different approach than expected
New research from Argonne National Laboratory and the UChicago Pritzker School of Molecular Engineering (UChicago PME) has solved a major battery mystery that has led to capacity degradation, shortened lifespan and, in some ...
Phys.org / Zero lasing modes are not always topological
The convergence of non-Hermitian physics and topological photonics has opened exciting research directions in recent years, particularly in the development of robust laser systems.
Phys.org / Billionaire Trump nominee confirmed to lead NASA amid Moon race
The US Senate on Wednesday approved President Donald Trump's re-nomination of billionaire Jared Isaacman to head NASA, following months of backtracking and uncertainty over the space agency's future.
