There are a number of annoying clichés of science reporting, prime among them being the need to make a connection from any research to a specific application. It must be deeply embedded in the journalism culture, or written in a handbook somewhere.
In medicine this means that any study that involves viruses or the immune system’s ability to fight off infection might lead to a cure for the common cold. Any study that has anything to do with cell function might lead to a cure for cancer. Almost any study of the brain might one day cure Alzheimer’s disease.
Add to this – any study that alters a metabolic parameter that changes with age might, of course, reverse the ageing process.
