One of the most intriguing puzzles in cosmology is the existence of supermassive black holes that seem to appear very early in the history of the Universe. Astronomers keep finding them at times when, by all that they understand about the infant Universe, they shouldn't be there. The standard theory of black hole formation suggests that they shouldn't have had enough time to grow as massive as they appear to be. Yet, there they are, monster black holes with the mass of at least a billion suns. The James Webb Space Telescope (JWST) has found a large population of them in early epochs, and they've been observed in very early quasars as well.

The New Scientist Book Club read Kim Stanley Robinson's acclaimed science fiction story about the first settlers on Mars in April – and had a lot to say about it

The books, TV, games and more that New Scientist staff have enjoyed this week

These unusual images were created by visual artist Daniel Regan by submerging Polaroid photographs in his ADHD medication, to represent his experiences with the condition through art

Our brains need to adapt quickly to meet the challenges of our digital world, but a rigorous new book by a neuroscientist brings hope that we can do it, says Graham Lawton

While exercise and diet are frequently recommended as a universal way to improve your health, some conditions require more careful treatment

Set on a planet whose population lives underground, Radiant Star is Ann Leckie's latest Radch-universe novel. Its rich characterisation and meticulous world-building shine through, says our science-fiction columnist Emily H. Wilson

Feedback has learned that, according to reports, Meta is building an AI version of Mark Zuckerberg to interact with staff. Feedback hopes this doesn't become a trend

It has been a dream of astronomers and solar scientists for ages. A new mission gives solar researchers a powerful new tool in their arsenal: on-demand, total solar eclipses. Launched in 2024, The European Space Agency’s Proba-3 mission has proven the feasibility of a free-flying, space-based coronagraph. Now, first science results from the mission are giving us a view of the origin of space weather. The results were recently published in the Astrophysical Journal Letters.

The idea of sending a swarm of tiny laser-sail powered spacecraft to our nearest exoplanet won't go away. While complex and punctuated with tough problems, the idea is the only realistic way of reaching another solar system this century, according to researchers. But the scientific benefits would be huge.

Every star that has ever lived has been slowly spinning down, losing rotational energy across billions of years until, at the end, it collapses. But new research from Kyoto University has revealed that the story is far stranger than that. Some stars, in their final moments, don't slow down at all, they spin up and nobody predicted it.

Stars are not born by chance. New research shows that the mass of a star cluster dictates exactly what kinds of stars it will produce from cool, dim dwarfs to blazing stellar giants ten times the mass of our Sun. It is a discovery that rewrites our understanding of how galaxies grow and evolve, and raises questions that astronomers will be grappling with for years to come.

Astronauts take time to adjust how firmly they grip and handle objects when moving between Earth and space, because the brain continues making predictions based on whichever gravitational environment it has most recently adapted to. Research from the Université catholique de Louvain reveals that this adjustment process works in both directions and sheds new light on how the brain anticipates and manages the risk of making mistakes.

A procedure that could be done in half an hour, and prepared ahead of time, could seriously reduce blood loss from severe wounds, such as during surgery

An experiment with a carbon material in a magnetic field has revealed a novel way for electrons to move, which doesn't fully belong in two or three spatial dimensions

A wave of dinosaur discoveries over the past decade has completely reshaped our understanding of these long-extinct animals. Palaeontologist Dave Hone spills the secrets of how dinosaurs lived, from how social they were to how much they really fought 

A message from the Jesus and Mo artist about this week’s cartoon, called “dump2”:

A slightly scatological resurrection from 2006 today. Normal service will be resumed next week.

Religion vs. science!

On top of Kitt Peak in the Arizona Desert, a robotic surveyor just completed a five year mission to catalogue the positions of tens of millions of galaxies. The Dark Energy Spectroscopic Instrument (DESI) has now created the largest, most detailed 3D map of our universe ever constructed. And it’s not done yet, its main mission has been extended through 2028.

Reports suggest that Apple is using defective chips originally destined for high-end devices to create its latest affordable laptop. Reusing partially broken chips is common practice for all device makers and produces less waste

At SBM we have two basic missions, which are really just different ends of the same spectrum. We are trying to raise the ceiling of rigorous science in the practice of medicine. This is a complex topic involving factors such as statistical methods, preregistering trials, p-hacking, and various forms of publication bias. At the same time we are trying to raise the […]
