Little chicks and big fireworks
Hello!
Finally, my embryo-marking technique is working!!! I'm using really really really fine wire to pke carbon into the embryos (so fine that it's only just visable without the microscope), but instead of trying to hold it with big clumsy forceps like I have been (well, actually very pointly little forceps but big and clumsy compared to the wire), I'm using it mounted into a glass handle so it doesn't keep bending in the wrong direction and breaking. I marked two embryos on Friday, with reasonably neat little tracts of carbon, and my supervisor has just emailed to say that they are still alive and that the carbon has moved. So hopefully I'll be able to start making several marks in each embryo and collecting some results now. I was starting to wonder whether it was actually physically possible to make tracts of carbon through the body of very young chick embryos - my supervisor has done it before in the limbs of older embryos but as far as I know it hasn't been done in such small ones before.
Last night I had dinner with some of my friends and then went to a bonfire night with the biggest bonfire I've ever seen, and some big fireworks to go with it. Today I'm doing more research for my CP submitted essay. I'm aiming to get enough done so that I can make a rough plan and then arrange to meet my essay supervisor to discuss it sometime soon, and I've also got the Oxford Clinical School open day coming up this week. I'll let you know what I think of it!
Bye!
