- Self-imaging of structured light in cylindrical systems unveils a new form of space-time duality
Photonics researchers from Tampere University, Finland, and Kastler-Brossel Laboratory, France, have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's structure with great potential for advanced optical communication systems. In addition, a new type of space-time duality was explored for powerful analogies bridging different fields of optics.
- Ultrasound-activated microbubbles form high-speed jets for drug delivery
ETH Zurich researchers have investigated how tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated by microbubbles penetrate the cell membrane, enabling the drug uptake.
- Omegon’s Advanced X N 152mm Dobsonian
A new series of Dobsonians are now available from Omegon. Steve Ringwood took the 152mm-aperture model for a spin, and found that as an all-rounder, it handled expertly.
- Euclid Unveils a Breathtaking Einstein Ring
The ESA’s Euclid telescope captured a stunning Einstein ring around NGC 6505’s core, formed as the galaxy bends and magnifies light from a distant background galaxy through gravitational lensing.
- Ancient jewelry made from meteorites discovered in Poland
Researchers have made a remarkable find in Poland’s Częstochowa Museum collection—several ancient ornaments made from meteoritic iron. A team of Polish and French scientists analyzed burial objects from two early Iron Age graveyards, Częstochowa-Raków and Częstochowa-Mirów. Their work has given us new insights into how early metalworkers used cosmic materials in their craft. The findings, The post Ancient jewelry made from meteorites discovered in Poland appeared first on Archaeology News Online Magazine.
- 2,000-year-old bronze divination spoon discovered on the Isle of Man
A unique bronze spoon from 2,000 years ago, thought to have played a role in divination rituals, has been uncovered on the Isle of Man. Rob Middleton, a metal detectorist, found this object on David Anderson’s farm in Patrick. This spoon stands out as the first of its type to surface on the island.

- Politecnico di Milano and Georgia Tech introduce new insights into asteroid deflection
Paris, France (SPX) Feb 21, 2025 How prepared is humanity to deflect an incoming asteroid? This question is addressed in two recent studies published in *Nature Communications*, stemming from a collaboration between Politecnico di Milano, the Georgia Institute of Technology, and other global research institutions. The studies analyze the outcomes of NASA's DART (Double Asteroid Redirection Test) mission, which successfully impa
- U-M astronomy will lead its first satellite mission with NASA grant
Ann Arbor, MI (SPX) Feb 20, 2025 The first space mission led by the University of Michigan Department of Astronomy is scheduled to launch in 2029 with the support of a NASA grant worth $10 million. The mission is called STARI-STarlight Acquisition and Reflection toward Interferometry-and will showcase the viability of a new technique for studying exoplanets, or planets outside of our solar system. The technique coul
