Nature is filled with remarkable visual phenomena created by microscopic surface structures that interact with light in fascinating ways. The iridescent wings of butterflies, the shimmering feathers of birds and the glossy surfaces of flower petals are all examples of how living organisms control the reflection, absorption and scattering of light. These optical effects are […] How do you take measurements using one of the most sensitive scales in the world? Researchers at TU Wien have demonstrated how the measurement process affects not only the object being measured but also the scale itself, and where the absolute limits of precision lie. Go to Source The asteroid that caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected. Go to Source Researchers at Kanazawa University, in collaboration with Diamond and Carbon Applications (Germany), have developed a buried-growth process for nitrogen–vacancy (NV) centers in diamond using microwave plasma chemical vapor deposition (MPCVD). By employing nitrogen-radical selective etching, which simultaneously enhances metal-mask durability through nitridation, the team enabled a continuous etching–growth sequence within a single MPCVD process. Go […] Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions during solar flares remain unresolved, including how and where particle acceleration occurs, and how energized electrons propagate through coronal magnetic structures.

Go to Source Luca Parmitano, an Italian astronaut, will be the pilot of NASA’s Artemis 3 mission, the first European to join one of the program’s missions, the U.S. space agency announced Tuesday.

The newly studied pair, FCC 224 and FCC 240, on the outskirts of the Fornax Cluster, share several unusual traits with the only known pair of controversial dark-matter-deficient galaxies. The […] Unfortunately, there’s more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA’s Ames Research Center, reports that 73.3% of images the agency’s new SPHEREx space telescope collected between May and September of last year were contaminated by at least one artificial satellite […] Quantum memories, systems that store and retrieve information leveraging quantum mechanical effects, can outperform classical storage systems on some existing tasks. Yet these promising memories could also complete operations that are very difficult or impossible for classical systems, including the storage and retrieval of so-called isometry channels. Go to Source When baseball fans watch a batter strike out with runners in scoring position, the reaction is often immediate: Shorten the swing. Put the ball in play. Stop swinging for the fences, they lament. Go to Source |
