Picking teams for the upcoming interspecies tournament of death...

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]

SVM, HMM, and wavelets in bioinformatics

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 aren't other carnivore species intelligent?

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 Problem of Scale: Halfway in size between an atom and the universe

"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?

(2) Can you give some examples of how some common farm, food, or pet animals might rank on the list? [more inside]
