due to mid-terms.. essays... presentation...cold... I was unable to take time to do some exciting experiments. Well.. I can take time to do them but I figured out that if I do my experiments hurryingly, my results might be bad bad bad.. then I have to re-do them again..etc So it is better if I get all my exams and homework done then do some experiments with great results!

Since I don't have experimental data to post.. I'll post something interesting I learned from my neuroscience class!

Botulinum toxin:
A type of botulinum toxin (BOTOX), "A", is used for the beauty treatment for facial lines and wrinkles.

How it works?
The toxin cleave the "snare" proteins needed to have vesicle fusion to occur. So without the fusion, no neurotransimitters are released --> no action potential --> muscles don't move

Good effects?
Your muscles don't move so the wrinkles seem to be gone.

Side effects?
Muscle degeneration! So with continuous use of Botox, your facial muscles will eventually be gone and more Botox will not help with the wrinkles anymore because you don't have any facial muscles left. (paraphrased from my prof)

BOTOX is bad! We should just be who we are... :-)
