Levitated magnet opens new frontier in search for ultraheavy dark matter
on September 5, 2026 at 10:15 am
Rice University researchers have used a magnetically levitated particle to search for ultraheavy dark matter, extending the hunt for some of the heaviest possible forms of the invisible matter thought to hold galaxies together. Led by Christopher Tunnell, associate professor of physics and astronomy, the researchers used a tiny floating magnet as a highly sensitive detector designed to register […]
A new type of LED light could bring significant efficiency gains
on September 4, 2026 at 10:00 pm
Researchers at Lund University have developed a new type of light-emitting diode based on thin, branched nanowires that could offer significantly higher efficiency and lower production costs than current technology. By controlling where in the structure the light is generated, the researchers have reduced the losses that would otherwise limit the amount of light that can be used. Their study is […]
Magic-angle graphene provides evidence for unconventional superconductivity
on September 4, 2026 at 9:20 pm
Researchers have completely suppressed superconductivity in magic-angle graphene by screening interactions between electrons, helping resolve a long-running debate about the origin of the phenomenon.
Embedded platinum channels bring nanoscale spin-based thermoelectric conversion to bulk materials
on September 4, 2026 at 7:40 pm
A joint research team from NIMS and the University of Tokyo has developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material by coating the surfaces of magnetic-insulator powders with a metal and sintering them. Using this structure, the team succeeded in observing thermoelectric conversion driven by spins in an insulator, a phenomenon previously […]
Ultrafast electrons and lasers reveal unexpectedly strong radiation signals in common semiconductors
on September 4, 2026 at 4:40 pm
Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that are strong but slow or fast but weak. The trade-off between signal strength and speed can limit precision detection.
