Several academic and scientific conferences in the United States have been postponed, cancelled or moved elsewhere, as organizers respond to researchers’ growing fears over the country’s immigration crackdown. Organizers of these meetings say that tougher rules around visas and border control — alongside other policies introduced by US President Donald Trump’s administration — are discouraging international scholars from attending events on US soil.

The scientific literature is at risk of becoming flooded with papers that make misleading health claims based on openly available data that are easy to process using artificial intelligence (AI) tools, researchers have warned. In a study published in PLoS Biology on 8 May1, scientists analysed more than 300 papers that used data from the US National Health and Nutrition Examination Survey (NHANES), an open data set of health records.

As attacks on US science by the administration of President Donald Trump continue, countries worldwide are stepping up their efforts to recruit US research talent. In the past few months, governments and institutions have launched programmes to attract scientists from the United States, where the Trump administration has made deep cuts to research budgets and begun dismantling science agencies.

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.
