    Madeleine Finlay sits down with co-host and Guardian science editor Ian Sample to talk through three eye-catching stories from the week, including the news that the number of years people in the UK are spending in good health has declined compared with a decade ago. Also on the agenda is the science, tech and nutrition behind two runners at this weekend’s London marathon breaking the two-hour threshold, and an answer to why some old houses feel particularly spooky.

    Apr 23 2026
    Madeleine Finlay sits down with science editor Ian Sample to hear about some of the winners of the Breakthrough Prize, which held its ceremony in LA last weekend. Each prize is worth $3m and they’re awarded in physics, maths and life sciences. Madeleine and Ian hear from molecular biologist Jean Bennett, who shared a life sciences prize for her work developing the world’s first FDA-approved gene augmented therapy for sight loss. She explains how a chance encounter while dissecting a brain in medical school led her on a 25-year journey to develop the treatment..
