It is sad to say that this will be the last post for the academic year; however I have enjoyed working in the VAOL with Brian, Tewa, and Lily and would like to do so again in the future. For … Continue reading
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
In the lab for the past couple of weeks we have been analyzing all of the data we have taken. We did this after we have only taken a few tests mainly to ensure that nothing is going wrong with … Continue reading
An expression used by experimenters and scientists regarding the collection and arrangement of data; the steps preceding the analysis of the data.
This week, we took data.
The CCD cameras have proven to be excellent. We drop the worm into the … Continue reading
Although this is not actually week 5 of being in the lab, it is the 5th week of work we have gotten to do. Last week we were unfortunately unable to run any tests due to conflict in timing with … Continue reading
Recall the problem of unfocused images when trying to observe the behavior of the worms when sent through two different wavelengths of light, side by side. The regular digital camera was producing such a tiny image that good data was … Continue reading
The CCD camera is not producing images. Up until now, it was possible to set up an effective laser setup just with “eyeballing it” (no math). Unfortunately, the CCD camera needs to be placed a specific distance from the closest … Continue reading
Due to a whole bunch of work that piled up over the past 2 weeks, I am combining weeks 3 and 4 into one post.
During week 3, Brian showed me a basic intro to analyzing diffraction patterns of c elegans … Continue reading
In the lab, things do not go smoothly line to line like in classroom physics problems. Experiments take endurance and patience: you will fail before you succeed.
Current project: Analyzing the C. elegans’ reaction to different light wavelengths (blue and red).
Problem: … Continue reading
