Asteroid hit the moon and flung rocks 120 kilometres from the crater

The crater site, before and after impactNASA/Mark S. Robinson et al. 2026 A newly formed crater on the moon is teaching us about our nearest neighbour’s complex geology. The crater, formed by an asteroid impact in 2024, is the largest that we’ve ever watched form in real time. It was first spotted last year, when researchers compared sets of images taken by NASA’s Lunar Reconnaissance Orbiter in both 2024 and 2025, and was named McGetchin crater. According to models of how often impacts occur on the moon, one this big – about 222 metres across – is only expected to occur about once every 132 years. While the moon has many larger craters, watching one as it forms and evolves presents a unique...

T. rex teeth show the enormous predatory dinosaur was warm-blooded

Tyrannosaurus rex was probably a warm-blooded predatorOrla/Shutterstock The world’s most famous dinosaur, Tyrannosaurus rex, was probably warm-blooded like birds and mammals, new evidence, obtained from 66-million-year-old tooth enamel, suggests, adding weight to previous findings. Scott Persons at South Carolina State Museum, who wasn’t involved in the new study, says the research means “the opening to the last Jurassic World flick was one big pile of Hollywood bunk”. “That film premised that dinosaurs could not survive in the modern world, except near the equator,” says Persons. “Not so. The evidence indicates that a Tyrannosaurus would be comfortable in subtropical and even mild climates....

From 10 to 22 years: The Nancy Grace Roman Space Telescope's mission has just been extended

The Nancy Grace Roman Space Telescope hasn't yet reached its Sun–Earth L2 orbit, and it already has some good news. NASA has announced that the mission has enough fuel to potentially double its mission length. Though initially scheduled for five years of observations, followed by a five-year extended mission, the entire mission could now reach 22 years.

Toilet pellets may help us flush less and save water

A pellet that dissolves in the toilet, turning the water blue and masking odor after urinating, could help us all save water, according to a first-of-its-kind study from the University of Surrey.

Prime assembly can correct multiple mutations at once, pointing toward universal gene therapies

Genomic editing holds great potential yet continues to have limitations. Current methods either rely on untargeted gene delivery or short DNA edits that need to be individualized for each patient. A new paper published today in Nature describes a novel genome engineering method called prime assembly that allows long DNA fragments to be stitched into precise, programmable target positions within living cells. This approach may allow for the development of universal gene therapies that can be used for many patients.
