I played a little more with Periscope in the lab this morning. First, I showed off my microscope, and I figured that that was enough babbling, and then went off to do my usual animal care chores. The fish kind of went wild and spewed out hundreds of eggs today, so I went ahead and put a typical 4 cell embryo on the imaging system. It looked nice! So I was going to wait a bit and let it divide and show an 8 cell embryo (powers of 2, they really do that), but the next division was in the plane of the screen, so I waited just a little longer and grabbed a picture of a 16 cell embryo. They’re just cruising along, as they do, dividing and dividing.
I also found it really hard to do microscopy one handed while aiming the iPad camera with the other, so you may get a little seasick watching the videos. Sorry. I may have to draft Mary to pretend to be a tripod while I do my schtick tomorrow.
Yep, tomorrow. I’ve got this big pile of blastulae today, and people don’t believe me when I say they’ll turn into little baby fishies in less than 24 hours, so I promised to come back and show everyone what these same embryos look like on Friday morning.
