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...
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.
Molecular glasses solve long-standing Arrhenius paradox
June 2, 2026 feature Molecular glasses solve long-standing Arrhenius paradox Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Glasses are non-crystalline but solid states of matter in which molecules and atoms are not arranged into a regular crystal lattice, but rather in a disordered pattern. Glassy materials are widely used in various settings, for instance, in the synthesis of pharmaceuticals and the development of electronics or optical devices. When...
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.
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...
Nickelate superconductors share a common electronic fingerprint
Nickelate superconductors share a common electronic fingerprint Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Superconductors, materials that conduct electricity with zero electrical resistance at specific temperature ranges, have proved very promising for the development of quantum computers and other cutting-edge technologies. While most of these materials become superconducting at very low temperatures, others exhibit superconductivity at higher...
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...
A kohl bottle from York may hint at an ancient Egyptian in Roman-Britain
May 31, 2026 feature A kohl bottle from York may hint at an ancient Egyptian in Roman-Britain Sandee Oster Author Sadie Harley Scientific Editor Robert Egan Associate Editor Ancient Egyptians are often depicted wearing black eyeliner, known as kohl, which was stored in small containers. While kohl containers are typically found throughout Egypt and Sudan (Nubia), their presence beyond these areas is limited to only a handful of examples. However, over 40 years ago, in 1983–4, an unassuming...
Violating the 3rd law of black hole mechanics in vacuum gravity
June 3, 2026 feature Violating the 3rd law of black hole mechanics in vacuum gravity Ingrid Fadelli Author Sadie Harley Scientific Editor Robert Egan Associate Editor Black holes, regions in space where gravity is so strong that nothing can escape, have been widely studied over the past decades, due to their unique and intriguing properties. Einstein's theory of general relativity predicts that black holes obey a set of rules, known as the laws of black hole mechanics. These rules somewhat...
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...
