Mathematician solves origami donut efficiency challenge with fewest folds
June 1, 2026 report Mathematician solves origami donut efficiency challenge with fewest folds Krystal Kasal Author Sadie Harley Scientific Editor Robert Egan Associate Editor Most people wouldn't think that it would take rigorous mathematical proof to show how many folds it takes to make a donut shape out of paper.
Black hole feeding bursts may explain JWST's Little Red Dots in early universe
June 8, 2026 report Black hole feeding bursts may explain JWST's Little Red Dots in early universe Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on May 29, argues that these objects could be black holes caught in rare, violent bursts of...
Tiny-armed alvarezsauroid dinosaurs might have been insect eaters, fossil scans suggest
June 1, 2026 feature Tiny-armed alvarezsauroid dinosaurs might have been insect eaters, fossil scans suggest Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Dinosaurs are estimated to have roamed Earth for over 165 million years, gradually evolving over time to survive in changing environments. Among the many fascinating groups of dinosaurs known to have lived on our planet are alvarezsauroids. These dinosaurs possessed extremely short but powerful forelimbs...
Inside Europe's largest Copper Age tomb, children's bones expose an ancient health crisis hidden for 5,000 years
May 30, 2026 feature Inside Europe's largest Copper Age tomb, children's bones expose an ancient health crisis hidden for 5,000 years Sandee Oster Author Sadie Harley Scientific Editor Robert Egan Associate Editor Nearly 5,000 years ago, respiratory infections, possibly including tuberculosis, were ravaging the children buried at Camino del Molino (CMOL), Spain. The massive circular burial cave carved into rock is Europe's largest Copper Age mass burial, containing over 1,300 individuals,...
Quantum memory surpasses classical limits for storing unknown quantum operations
June 9, 2026 feature Quantum memory surpasses classical limits for storing unknown quantum operations Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Quantum memories, systems that store and retrieve information leveraging quantum mechanical effects, can outperform classical storage systems on some existing tasks. Yet these promising memories could also complete operations that are very difficult or impossible for classical systems, including the storage and...
Predictive surrogates could cut quantum computing measurement overhead by more than 99.97%
June 6, 2026 feature Predictive surrogates could cut quantum computing measurement overhead by more than 99.97% Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of outperforming classical computers on some tasks. Despite their potential, the use of these systems remains very limited, due to their high cost and other challenges that have so far...
JWST finds a stellar bar in the early universe that breaks all rules
May 31, 2026 report JWST finds a stellar bar in the early universe that breaks all rules Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor 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 14. Cosmic funnels Stellar bars are elongated arrangements of stars that cut across the center of...
A giant star may have destroyed itself in one of the universe's rarest explosions
June 1, 2026 report A giant star may have destroyed itself in one of the universe's rarest explosions Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor Astronomers may have discovered one of the clearest examples yet of a rare "pair-instability" supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving behind no remnant. The paper outlining the properties of this rare explosion was...
Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy
June 2, 2026 report Dormant black hole revives in under three years, brightening 10-fold in nearby galaxy Shreejaya Karantha Author Sadie Harley Scientific Editor Robert Egan Associate Editor Astronomers monitoring a nearby active galaxy for six years have watched its supermassive black hole dramatically wake up, brightening by a factor of 10 across ultraviolet and X-ray wavelengths. The paper outlining the study was posted to the preprint server arXiv on May 18.
Nanoengineered materials can store and release hydrogen at room temperature
June 1, 2026 feature Nanoengineered materials can store and release hydrogen at room temperature Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Energy engineers worldwide are working on various new technologies that could help to limit greenhouse gas emissions on Earth and address climate change. One proposed alternative to polluting fossil fuels, such as petrol, diesel and natural gas, is hydrogen. Hydrogen is a clean fuel that can be used to power fuel...
