I assume at some point in our evolutionary past it was somewhat attractive. So when and why did it become the direct opposite?

a bloke at work as told me that scientist can detect potential peadophiles and murders useing there dna! He said he saw a documentary a while bk saying that these 'evil' people have anomalies in there dna that cause them to do these acts! Is this true?

I wonder if he has any clients left since he went public with his claims of participating in time travel experiments. You have to admit that he is quite well spoken and sounds very convincing though

why do foods taste so differant? Beef and lamb tast very differant but are both muscles, isn't muscle made from the same nutrients so shouldn't they taste the same?

how does peritineum dialasys work?

This may seem like an odd question, but when I came to think about it, the whole rectangle and An, system seems fairly arbitrary. Where did it come from and why?

why not the golden ratio say, or a square? Both seem perfectly valid options...

why in certain events are they dominated by one type of human? E.g. Sprinting events is majority black people long distance is dominated by kenyans and eithiopians and field events are white people?

Here's a snippet:

"Although neutrinos are very light and therefore well within the energy reach of colliders, they are impossible to directly detect at the LHC because they have no electric charge and therefore interact only weakly--so weakly that although more than 50 trillion neutrinos from the Sun pass through you every second, you really have no idea until someone tells you." page 244, Knocking on Heaven's Door, Professor Lisa Randall

I have a little mystery for you all. Why do nettles catch fire in a microwave?

Ideas anyone? :?

can you heat a liquid by stiring it? My thought is that if u whisk up water the molecules are been moved about quickly there bumpinjg into each other causeing friction then heat?
