• Andrew Steele is a British science writer and YouTuber. He earned a PhD in physics at the University of Oxford and then moved into computational biology at the Francis Crick Institute in London.
• He chose ageing research because he sees ageing as the biggest cause of disease and death, and therefore the most important scientific problem.
• In his book Ageless: The New Science of Getting Older Without Getting Old (2020) he covers the biological hallmarks of ageing and the treatments in development, from senolytics to stem cells and gene therapy.
• He argues that ageing is a biological process that can be targeted, and that research into it deserves far more attention and funding.
• On his YouTube channel he explains new ageing research accessibly, with references to the studies.
• For longevity, he is a clear guide who combines enthusiasm for the field with honesty about what is not yet proven.
• Takeaway: he himself stresses the proven basics — not smoking, exercise, good sleep, a healthy weight, vaccinations and good oral hygiene.
