Status Updates From Adrenaline

GUYS. THIS IS SO COOL. "[T]he amino acid sequence of the β2 receptor proved very similar to the known structure of ... the eye protein responsible for detecting photons: Rhodopsin responds to photons by activating the G protein [that] stimulates biochemical changes that trigger the perception of light. In other words, the first steps in light perception are biochemically analogous to how cells respond to adrenaline."

When my sister brought this inter-library loan home for me, she said, "At first I thought it was a thriller—you know, all those one-word titles—but then I looked inside and it's actually about adrenaline."

Yup. Not a thriller. I keep wanting to shelve the book as 'biography,' because it is essentially a biography of adrenaline. It's quite interesting so far.
