Friday Physics #6 - Bio Bash Edition

Good morning everyone! While the lovely FlowerGirlPhysicist is away, I shall be taking over Friday Physics and making it all about the biology. So move over the circuits and particle accelerators, and bring in the agar plates and incubators. Let's do this.

A bit about my background: I'm a PhD student in Immunology...so if you've got any questions about immunity and disease I've got you. Everything else, I will answer the best I can, and may need to resort to google or pubmed.

Biology is a huge field, so I will have my bestie, who is an evolutionary geneticist, to help out. And I know there are some other biologists out there, so feel free to chime in.

Of course, let me know if I use too much jargon, and FYI there will be a break for a while in the afternoon. (Fun plans for today: helping kids give science presentations with cheap, handmade microscopes...and getting my taste buds profiled as part of a control group for a study).

So hit me with your random questions!

ETA: I did not realize I would get paid in animal pics. THIS IS GREAT! Thanks guys =)
