There might be a paradox in the biology of ageing. As humans grow older, their metabolisms tend to slow, they lose muscle mass and they burn many fewer calories. But certain cells in older people appear to do the exact opposite — they consume more energy than when they were young. These potential energy hogs are senescent cells, older cells that have stopped dividing and no longer perform the essential functions that they used to.

If you’ve ever had a biopsy, you — or at least, your excised tissues — have been seen by a pathologist. “Pathology is the cornerstone of diagnosis, especially when it comes to cancer,” says Bo Wang, a computer scientist at the University of Toronto in Canada. But pathologists are increasingly under strain. Globally, demand is outstripping supply, and many countries are facing shortages. At the same time, pathologists’ jobs have become more demanding.
