reading, writing, and everything in between

Be skeptical.

That's what my advisor told me when I brought in a few papers a while back. And also what he said when it got to explaining my rationale behind my experiment predictions.

Part of my work involves an enzyme called AMPK, so I've been doing a bit of reading on it. But since it's such an ubiquitous protein, there's been a lot of work done on it already, even if I look into specifically what its role is in food intake control (another part of my project). So to organize my thoughts and see what parts I was still missing out on reading about, my advisor asked me to write a minireview (~5 pages) about AMPK and its role in feeding control in the brain, so that's what I've been doing in my "spare time" for the last two weeks.

Writing it was a little harder than anticipated. The first day of writing, it took me about three hours to write a paragraph. Not because I didn't know how to word things; it was because I was averaging one citation a sentence. Which means for every sentence I write, I have to read an entire paper written by someone else. I suppose I could read a whole bunch of abstracts and string them together to make an instant review, but that's out of the question. First off, my advisor is going to know whether or not I really read the papers; and second, sometimes the abstracts will sugarcoat things, and unless the reader looks into the methods, it'll seem like everything is legitimate.

I'm also in the process of scribbling ideas to write for my written prelim exam. In general, my project has to be on leptin in the frog, but since it wasn't cloned until 2006, there's still a lot of basic info we don't know yet, like if it signals through particular pathways, or if it is produced in a certain way. These basic questions have already been answered in mammals, and it seems to me like a lot of the mammalian studies nowdays are focusing more on different brain regions that leptin acts on, how they "talk" to each other, where other signals might come from, etc. It would be pretty boring (not to mention very uncreative) of me to base my written exam off of the statement "This stuff about leptin is true in mammals. Please give me money so I can do the exact same thing in frogs."

So now I'm kinda stuck on how to use the frog as a model to advance the field. Which probably translates to "I should read a lot more..."
