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]

I'm interested in cells. As many different types as can be identified, and the more specific the better. Preferably mammalian, certainly vertebrate (otherwise the the list would be too big!). [more inside]

Most animals (herbivores, carnivores, and omnivores alike) seem to eat and/or prefer food from a very limited set of options. But humans eat just about everything. Are there foods that humans are more biologically disposed to eat? Alternatively, are there other animals that eat foods as widely diverse as humans do?

Can anyone recommend a good digital thermometer for humans? We have several, which we bought at the drugstore for $10 or so, and they all suck. They all give readings that vary by as much as two degrees when you take your temperature twice. Often they seem to under report temperature. I just took mine with a new one we bought, and typically, it reported my temperature as 94.5 the first time, and 97.9 the second. My wife got similar results. We have a new baby, and would like a good thermometer. We'd be willing to spend a lot more on it than ten dollars if it works well. Can anyone recommend one?

[Two Obscure SciFi Short Story Questions]
When I was a kid our family library was stocked with lots of 'Best Of' Sci Fi collections. One particular story that I half remember had something to do with the human race being enslaved by large aliens, and basically a slave revolt by humans occurs in one of the alien ships. The other story was about an alien artifact (a helmet?) and some quasi-Egyptian pyramid ruins. That's really about all I can remember, other than I remember enjoying both stories very much. Any ideas? [more inside]
