My wife is an anatomy professor and needs help with this question: Most anatomy textbooks say that urination and defecation are controlled by the parasympathetic nervous system (aka "rest and digest system") Then why is it that some lose bladder and bowel control in frightening situations? Isn't the opposing sympathetic "fight or flight" system supposed to in charge?

Good way to get 'refreshed' on Biology? I took 1st year BIO 8 years ago. I'm taking the second semester this summer and don't want to be completely lost. What are some good ways (whether online, dvd, book, etc) to get this done? I'll probably go to a Bio 1 class and pick up the syllabus, but would like some suggestions. I'll have about 6 weeks to do the 'refresh'
How does the caterpillar become the butterfly (why does one part of the chrysalis know to become a leg, and another a wing)? Is it as simple/complicated as the cell division of a human fetus? Does the transformation of this jelly into a butterfly occur from the head down, or all at once? Anyone? [more inside]

Name-my-major, Hivemind. So I go to an unusual school in that we don't have clear-cut majors, and we basically pick an area of "focus". I'm actually currently (unofficially) studying my own brain, because it's strangely hampered in certain capacities (like the process of reading music, despite being very musical and understanding cognitively exactly what's going on), or performing basic math (despite endless repetition). It's also weirdly bolstered in other regards: I have an unbelievable propensity for forming the visual "distortions" one might associate with hallucinogens. [more inside]

At a cocktail party last weekend, an Anthropologist was telling me about an experiment/study where people were shown videos of various animals preying on one another, and then measured their reactions. The findings, he contends, were that humans were largely more sympathetic to the deaths of animals more similar to themselves (i.e. sharing a more recent common ancestor). What is this study, what is this area of research called, and where can I read more about it? [more inside]

I'd like to learn about SVM, HMM and wavelet algorithms in their usage in bioinformatics. I have a somewhat rudimentary understanding of the underlying mathematics from Wikipedia and a couple other sources, but I find that a concrete demonstration of their application fleshes it out. Are there texts, software packages (preferably free) or papers you'd recommend that: 1) includes good starter problem sets, or; 2) demonstrates how these techniques are used in research applications (beyond "we used xyz here"). Thanks!

Teaching resources about racial concepts: their biological validity and various cultural expressions
I need teaching resources about race: the biology of human "races"; why "race" is not biological but social; how racial categories have shifted over time and place; and related questions on teaching about race? This is as a supplement to reading The Mismeasure of Man in a university "Critical Thinking" class. I need more science and verifiable cross-cultural examples to back up my "there are no biological races" claim. [more inside]

Why are there no freshwater squid?
First off, please excuse me for being a Biology ignorant. I seem to remember reading somewhere that men are so intelligent today because of they high protein consumption, in form of meat, which caused the brain to grow during evolution, making our species more intelligent than the others. If this is true, why don't we have superintelligent lions and other carnivore animals walking on twos and building cities and electing the mayor in Lionland, PA? They eat way more meat than we do.
"A human is halfway in size between an atom and the known universe"... This is a paraphrased quote I have come across several times. I like it. Who said it first? How true is it in the most literal sense? And, finally, what errors arrive in postulating a universe, or an atom, which can be measured AT ALL from our singular, relativistic, perspective?
