Tech Xplore / In Finland, radioactive spent nuclear fuel soon to be buried underground
The elevator display reads "433", the number of meters below ground. The doors slide open, revealing the entrance to what is expected to be the world's first permanent repository for radioactive spent nuclear fuel.
Phys.org / Fiber optic components enable high-performance 2-µm fiber lasers
Laser systems operating in the 2-micrometer wavelength range open diverse opportunities in medical technology, agriculture, and plastics processing. In the Eurostars project DECOMP, Laser Zentrum Hannover e.V. (LZH) has developed ...
Medical Xpress / Can AI beat breast cancer?
An artificial intelligence (AI) system that combines breast cancer tissue images with molecular marker data achieves high accuracy in diagnosis, tumor classification, and survival prediction. Details of the research are reported ...
Tech Xplore / Efficiently cooling satellite components in space
Space is a vacuum. Heat therefore cannot be transferred to the surroundings by thermal conduction. This poses a problem for any type of space-capable electronics, which can quickly overheat under these conditions. The only ...
Phys.org / Taking dark energy out of the equation: Mathematicians challenge the standard cosmological model of the universe
Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians from the University of ...
Phys.org / JWST finds a stellar bar in the early universe that breaks all rules
Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 billion years after the Big Bang. The new paper was submitted to the preprint server arXiv on May ...
Phys.org / Could aliens ever visit Earth? An aerospace scientist unpacks the challenges of interstellar spaceflight
On May 22, 2026, the Pentagon released a second batch of previously classified photos and videos showing what appear to be unexplained flying objects. These file dumps were the culmination of a process that was set in motion ...
Phys.org / Supermassive black holes could be the universe's biggest planet nurseries
Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when ...
Phys.org / Webb reveals black hole that formed before its galaxy
Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can ...
Phys.org / Listening to the sun reveals previously hidden changes to solar cycle
Internal changes due to the sun's "active biorhythm" have become increasingly "skin-deep" over the past four solar activity cycles, according to a new study.
Medical Xpress / Move more for your health, not just for the scale
With obesity now affecting more than 40% of U.S. adults and fueling rising rates of heart disease, a new scientific statement from the American Heart Association calls for a comprehensive treatment approach that puts physical ...
Phys.org / The solar wind's secret hammerheads and what they tell us about heat in space
The proton sharks showed up on a Friday. In a routine data calibration meeting for NASA's Parker Solar Probe in 2020, a small group of scientists were scrolling through visualizations of their data showing solar winds. Suddenly, ...
