Last official update!
This week, along with taking more data, we also took a cursory look at all the videos so far and simply counted how many worms “turned around” or “hovered” during the data collection. This was just to take … Continue reading

Current project: Analyzing the C. elegans’ reaction to different light wavelengths (blue and red).
Problem: … Continue reading
