Last month, economist Matthias Doepke packed up three decades of his life in the United States and resigned from his job at Northwestern University. He sold his house in Evanston, Illinois, and joined his wife and three children in London.

Scientists have found a way to map the intricate patterns of cells in mouse brain tissue with an off-the-shelf light microscope, using a trick that inflates a tiny sample to 16 times its original size. Until now, charting the tangled forest of neurons in the brain — known as the connectome — required an electron microscope. These are powerful but expensive machines that cannot generate coloured images.

A system that helps visually impaired people to navigate their surroundings using cameras, earphones and artificial intelligence (AI) could offer advantages over white canes and other conventional technologies. The system uses AI to interpret footage from camera mounted on a pair of glasses, and feeds the wearer information on their location in real time through audio alerts and vibration. The AI revolution is coming to robots: how will it change them?

Researchers have created the largest and most detailed wiring diagram of a mammalian brain to date, by mapping cells in a cubic millimetre of a mouse’s brain tissue. In a landmark achievement, the diagram also details the activity of individual neurons on a large scale―a neuroscience first. The high-resolution 3D map contains more than 200,000 brain cells, around 82,000 of which are neurons.

A biotechnology journal that was inundated with paper-mill submissions in 2021 — and claimed in 2023 that it had tackled the problem — still harbours hundreds of dubious papers, an analysis by research-integrity sleuths has found. At least 226 studies on rodents published in the open-access journal Bioengineered between 2010 and 2023 contain manipulated or duplicated images, says the analysis, which was posted on the arXiv preprint server on 28 March1.

A brain-reading implant that translates neural signals into audible speech has allowed a woman with paralysis to hear what she intends to say nearly instantly. Researchers enhanced the device — known as a brain–computer interface (BCI) — with artificial intelligence (AI) algorithms that decoded sentences as the woman thought of them, and then spoke them out loud using a synthetic voice.

A study of families who have lived through conflict in Syria suggests that genetic imprints of their trauma have been passed to their children and grandchildren. The research1 focuses on the controversial idea that trauma can leave ‘epigenetic marks’ on a person’s genes that can be passed onto following generations. Not all scientists agree that trauma can be inherited in this way and the mechanism for such inheritance is not known.

This February, ecologist Timothée Poisot was surprised when he read through the peer reviews of a manuscript he had submitted for publication. One of the referee reports seemed to have been written with, or perhaps entirely by, artificial intelligence (AI). It contained the telltale sentence, “Here is a revised version of your review with improved clarity and structure”, a strong indication that the text was generated by large language models (LLMs).

Immune cells in the skin ‘cauterize’ open wounds and create ‘band-aids’ to prevent the spread of harmful bacteria and foreign molecules from injury sites, finds a study1 in mice. The works shows that white blood cells called neutrophils form gooey, protein-rich rings around sites where the skin has been breached. These rings trap pathogens, ensuring that they don’t penetrate into deeper tissues.
