Pro Tips for Choosing Your Topic

  • Focus on a single 'moment of realization' to anchor your narrative.
  • Use sensory details (the smell of agar, the hum of the centrifuge) to ground the reader in the lab.
  • Ensure your biological terminology is accurate but accessible to a general scientific audience.
  • Connect your personal experience to a larger scientific debate or theory.
  • Don't shy away from experimental failure; some of the best biological narratives come from what went wrong.
