Playing a mental speed-training game seems to help the brain clear a protein linked to Alzheimer’s disease in men, but may work in women through different mechanisms
An experimental immunotherapy has beaten aggressive brain tumours in a handful of children, and a personalised version is now being tested on more patients

How can you have a proof without proving anything? Mathematicians found a way and, in the process, came to blows over it – but 100 years on, this trick is a common part of modern maths, says columnist Jacob Aron

Egg cells missing a key protein may be more likely to end up with the wrong number of chromosomes, but an mRNA injection that helps the cells make the protein reduces the problem

Fossils of Spriggina floundersi provide the earliest evidence of animals favouring one side of the body over the other – a feature of nervous systems that we see in our own right- and left-handedness
