Well, my students are done with their project other than their presentation
next week. Time to get out and shoot some photos. I took a few for them when
they were working.
They were trying to get DNA out of these:

that is a millimeter ruler next to that codling moth larval skin. I put the
100 APO on a bellows and it worked very well. Much better than the enlarging
lens I had been using on the bellows. A bit big and awkward, but the results
were amazing.
Here they are working away in the USDA Lab.

They were extracting DNA, amplifying a particular odorant gene, cloning it,
pulling it out and then having it sequenced for the researcher who runs the
lab. Here he is working at the UV light table cutting bands out of a gel.

Fun project and they did a good job. What they found out will enable the
researcher to extract DNA from the thousands of insect larvae he will have over
the next 6 months.
Comments welcome. I will return to more traditional photography now.
