- Twisting light: Novel metasurface offers compact solution for circularly polarized light
Left and right circularly polarized light, where the electromagnetic waves spiral in a clockwise and counterclockwise manner as they travel, plays a crucial role in a wide range of applications, from enhancing medical imaging techniques to enabling advanced communication technologies. However, generating circularly polarized light often requires complex and bulky optical set-ups, which hinders its use in systems with space constraints.
- Peeling back the layers: Exploring capping effects on nickelate superconductivity
So-called "infinite-layer" nickelate materials, characterized by their unique crystal and electronic structures, exhibit significant potential as high-temperature superconductors. Studying these materials remains challenging for researchers; they have only been synthesized as thin films and then "capped" with a protective layer that could alter properties of the nickelate layered system.
- The Quadrantids: a strong meteor shower to start the year
The Quadrantid meteor shower kicks off the meteor-watching calendar, peaking this year on 3 January. Renowned for its reliability, it consistently ranks among the best annual meteor displays.
- Catch Mercury’s end of year pre-dawn show
Mercury ends the year on a high as a pre-dawn object during primarily the second half of December.
- Major Roman pottery industry unearthed in Dorset, England
Archaeologists from Wessex Archaeology have discovered evidence of a substantial Roman settlement on land near Poole Harbour in Dorset, England. Finds come from “The Moors at Arne” project, a compensatory habitat scheme aiming to transform 150 hectares of grassland into wetlands. Excavations so far, in partnership with the Environment Agency, have identified over 17,000 pieces The post Major Roman pottery industry unearthed in Dorset, England appeared first on Archaeology News Online Magazine.
- Neolithic ‘sun stones’ sacrificed in Denmark to revive the sun after volcanic eruption
Around 4,900 years ago, Neolithic communities on the Danish island of Bornholm ritually buried hundreds of engraved stones, so-called “sun stones,” in a remarkable act to counter drastic climate changes caused by a massive volcanic eruption. The eruption was identified in ice cores by the Niels Bohr Institute at the University of Copenhagen as having The post Neolithic ‘sun stones’ sacrificed in Denmark to revive the sun after volcanic eruption appeared first on Archaeology News Online Magazine.
