Researchers have demonstrated a technique that uses a laser to produce a plasma beam antenna capable of transmitting radio waves.

Even the most chaotic quantum systems keep a permanent mark of their own past – a "quantum birthmark" – that never fades. Researchers from Tampere University, Harvard University, and TU Dresden discovered the feature in their recent study. These findings shed new light on the elusive relationship between classical and quantum mechanics. Looking ahead, these quantum birthmarks, along with related phenomenon known as "scars," could eventually be harnessed to power next-generation nanoelectronics.

Saitama University research team has developed a defect-state engineering strategy that transforms waste polyamide into carbon quantum dots with continuously tunable photoluminescence. By systematically changing surface chemistry through oxidation and boron-, nitrogen-, sulfur-, and phosphorus-containing modifications, the researchers shifted emission from ultraviolet at 308 nm to yellow-green at 552 nm using the same polymer precursor, while establishing a quantitative framework for understanding how engineered defect states control light emission.

A new review in National Science Review unveils anti-visual perception as a cross-disciplinary arms race spanning biomimetics, spectral physics, and AI. From snow leopards and dazzle camouflage to UV-to-microwave signature control and adversarial attacks on machine vision, it reveals how every advance in seeing drives new ways of hiding—offering a roadmap for next-generation camouflage, stealth, robust sensing, and trustworthy AI.

Physicist Gabriele Grosso has been selected as one of 21 mid-career scientists to join the 2026 Gordon and Betty Moore Foundation’s Experimental Physics Investigators Initiative cohort. The five-year, $1.35 million award will allow Grosso and his lab to pursue an unconventional idea in quantum science: Instead of treating tiny vibrations inside materials as a problem to be eliminated, researchers will endeavor to put them to useful work.

Distinguished Professor Chihaya Adachi of Kyushu University has been named a 2026 Clarivate Citation Laureate for his pioneering contributions to thermally activated delayed fluorescence (TADF), a breakthrough approach that enabled highly efficient OLEDs without rare metals and transformed organic electronics.
