Your DNA is under constant assault. Ultraviolet light, environmental toxins, reactive molecules made during run-of-the-mill metabolism and many other disruptors muck with the instructions that keep life humming along. Thankfully, repair crews are at the ready. This method to reverse cellular ageing is about to be tested in humans A typical cell can acquire up
An enzyme cuts DNA (artist’s impression). Synthetic enzymes that cleave proteins were rapidly designed with the help of artificial intelligence.Credit: Artur Plawgo/Scientific Photo Library Scientists have leveraged artificial intelligence models to create synthetic CRISPR proteins that edit the genome more efficiently than their natural counterparts. These synthetic CRISPR systems could one day drive discoveries in
