Over the past month Thomas “Tom” Johnson has passed away, a pioneering scientist who played a major part in modernising ageing research. Before his work, ageing was often seen as a complex and elusive process. Johnson demonstrated that it is possible to influence lifespan, something previously unimaginable.
In the 1980s, he achieved groundbreaking breakthroughs with his research into tiny worms, known as nematodes. He discovered that simply by breeding these animals, their lifespan could be significantly extended. After that, he demonstrated that a change in just a single gene could increase the lifespan by more than 50 percent. This was revolutionary at the time and was met with scepticism by many colleagues.
Johnson inspired a new generation of researchers, including two key scientists from the Buck Institute. Despite the criticism that ageing research was not serious science, many young scientists found a place in his lab to make real progress. His approach set the tone for years of intensive study into the biological basis of ageing.
Thanks to his work, today we can better understand which processes determine lifespan and how we can influence it. These insights are of great value to anyone who wants to age healthily and slow down the ageing process.
