EPISODE 30: Timelines of Ageing – What Worms Teach Us About Growing Old

In this episode, we dive into a new version of WormGazer as described in a recent GeroScience paper. This implementation automates movement monitoring in C. elegans populations as a rapid healthspan measure, offering a shortcut to detect ageing interventions and trade-offs.

Highlights include:

• Monitoring multiple Petri dishes in parallel with cameras and image analysis over 7–14 days

• Showing that most functional decline happens in the first week of adulthood

• Validating with age-1(hx546) mutants, which remain active longer but move more slowly early on

• A dose-response test with sulfamethoxazole (SMX) where movement improvements are detectable within 7 days, compared to 40 days needed for traditional lifespan assays

• The benefit: non-invasive, scalable, and faster detection of ageing effects and negative trade-offs

📖 Based on the research article:
