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.
Saturday Citations: Greenland sharks; quantum weirdness; people are mostly pretty chill
June 6, 2026 report Saturday Citations: Greenland sharks; quantum weirdness; people are mostly pretty chill Author Gaby Clark Scientific Editor Robert Egan Associate Editor This week, researchers reported that GLP-1 medications may influence the biology of aging. Hidden meltwater in deep Antarctic coastal waters has a strong climate impact.
Volcanic eruptions linked to rising famine risk across China's history
June 6, 2026 feature Volcanic eruptions linked to rising famine risk across China's history Hannah Bird Author Gaby Clark Scientific Editor Robert Egan Associate Editor Large volcanic eruptions may have played a bigger role in triggering historical famines across China than previously understood, according to a new study that traced links between eruptions, climate disruption, and food shortages over more than four centuries. By analyzing historical records from 1440 to 1900, Richard Warren...
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...
Supermassive black holes could be the universe's biggest planet nurseries
May 31, 2026 report Supermassive black holes could be the universe's biggest planet nurseries Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor 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 they are active, as well as destroy anything that gets too close. But their reputation could be due for a...
Critically endangered Chinese pangolin found in Nepal's sacred forest
June 8, 2026 report Critically endangered Chinese pangolin found in Nepal's sacred forest Paul Arnold Author Lisa Lock Scientific Editor Robert Egan Associate Editor The rare Chinese pangolin (Manis pentadactyla) has been spotted for the first time in Sunsari District in eastern Nepal. This brings the total number of districts in the country where the critically endangered species has been documented to 28. Chinese pangolins are small, solitary, nocturnal mammals native to South and...
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...
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...
Quantum light gives a 20-fold boost to ultrafast laser processes
May 30, 2026 report Quantum light gives a 20-fold boost to ultrafast laser processes Sam Jarman Author Gaby Clark Scientific Editor Robert Egan Associate Editor Nonlinear interactions between light and matter are at the heart of some of the most powerful tools in modern optics, but pushing these processes to their limits has long been hampered by a fundamental constraint: the stronger you make the laser, the more likely it is to destroy whatever it illuminates. Through new experiments...
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...
