It took Kazuo Ishiguro a long time to write his best-selling novel Never

Spreading crushed basalt rock dust on fields UNDO Projects that spread rock dust on farms are removing more carbon dioxide from the atmosphere than competing technologies – but CO2 removal efforts remain far short of what is needed to avoid dangerous levels of global warming. Known as enhanced rock weathering, the method involves spreading crushed

Judges can use algorithms to help make their decisions Frances Twitty/Getty Images A US courtroom experiment suggests a popular risk assessment algorithm makes harsher recommendations than human judges – possibly because it is worse than people at anticipating which defendants will violate pretrial agreements. “Some jurisdictions wanted to work with us to evaluate whether these

A Martian meteorite nicknamed Black Beauty Carl B. Agee (University of New Mexico) Crystals inside a Martian meteorite hint that there may have been plentiful hot water on Mars when the rock formed 4.45 billion years ago. The rock, nicknamed Black Beauty, was blasted into space by an impact on the surface of Mars before

Satellite image showing channels that formed part of an ancient fishery, and Mayan sites nearby Google Earth Archaeologists have discovered a massive network of ancient fisheries in Belize constructed by hunter-gatherers some 4000 years ago. The system of earthen channels exceeds 640 kilometres in length and dates to the Archaic Period, which preceded the emergence

Bacteria on a sample from the Ryugu asteroid, viewed with an electron microscope Matthew J. Genge et al. 2024 A rock from the asteroid Ryugu that was brought back to Earth appears to be festooned with microbial life. But these microbes almost certainly came from Earth rather than outer space, say researchers. This contamination serves

Millions of US residents may be drinking water containing the potentially harmful compound Yiu Yu Hoi/Getty Images A common disinfectant in drinking water breaks down into a chemical compound that we know almost nothing about, including whether it has any potential toxic health effects to those who drink it. Chlorine has been used to sanitise

Calçada Astronomers have taken the first detailed picture of a star in another galaxy, more than 160,000 light years away. The giant star may be showing

A pigeon-inspired robot has solved the mystery of how birds fly without the vertical tail fins that human-designed aircraft rely on. Its makers say the prototype could eventually lead to passenger aircraft with less drag, reducing fuel consumption. Tail fins, also known as vertical stabilisers, allow aircraft to turn from side to side and help

Calories on menus mean we can no longer pretend that fast food is slimming David Paul Morris/Bloomberg via Getty Images When you go to a restaurant, you may well be presented with a wide array of dishes, each printed on a menu alongside its calorie content. A chicken burger and fries may come to 1597

Sparks Albert Einstein’s theory of general relativity has been proven right on the largest scale yet. An analysis of millions of galaxies shows that the way they have evolved and clustered over billions of years is consistent with

Bluesky sign-ups continue to grow Anna Barclay/Getty Images As a technology reporter, I like to think I’m an early adopter. I first signed up to the social network Bluesky around 18 months ago, when the platform saw a small surge in users disaffected by Elon Musk’s approach to what was then still called Twitter. It

How did Earth’s inner core freeze solid? Rost9/Shutterstock A high concentration of carbon within Earth’s inner core could explain a long-standing mystery about how the deepest part of our planet froze solid – a process that kick-started the magnetic field protecting life on the surface. Earth’s inner core presents a paradox for geophysicists: it first

The white or blueish spots are six images of the same quasar created by the lensing effect of two galaxies, one appearing as the light patch in the centre and one as a red arc F. Dux et al. A chance alignment between two massive galaxies could help astronomers better measure the expansion of the

Baku, the capital of Azerbaijan, is located on the western shore of the Caspian Sea, but falling water levels could leave the city and oil infrastructure cut off from the sea VANO SHLAMOV/AFP via Getty Images Ports, oil drilling rigs and coastal settlements will be marooned kilometres from the shore as climate change drives water

A methane plume at least 4.8 kilometres long billows into the atmosphere south of Tehran, Iran NASA/JPL-Caltech The world has more ways than ever to spot the invisible methane emissions responsible for a third of global warming so far. But according to a report released at the COP29 climate summit, methane “super-emitters” rarely take action

Do you speak AI? Shutterstock/Ole.CNX Microsoft has created an artificial language that allows AI models to talk to each other faster and more efficiently than in English, with the hope that groups of models will be able to team up without having to resort to clumsy and sprawling human words. Many researchers believe that using
