Area of Science:

  • Aging research
  • Genetics
  • Biotechnology

Background:

  • Lifespan is influenced by complex genetic, environmental, and stochastic factors, leading to variability even in identical individuals.
  • Studying molecular mechanisms affecting lifespan requires analyzing statistical effects on populations, often using survival assays in model organisms like Caenorhabditis elegans.

Purpose of the Study:

  • To develop a scalable imaging and analysis platform for rapid acquisition of survival curves at high statistical resolution.
  • To enable detailed reverse-genetic and chemical screens for factors influencing survival and aging.

Main Methods:

  • A scalable imaging and analysis platform was developed to observe nematodes over multiple weeks.
  • The platform operates across large agar surfaces with high resolution (8-μm) and automates the tracking of individual deaths.
