Biology - July 2007

I have heard about the type of kinesis, biokinesis, and was wondering if anyone could tell me how to do it?
I have heard the whole 'DNA stream' thing, and don't really get it.
Any help would be really appreciated

We all know the classic prank. Someone is asleep. You fill a bowl with warm water, and place the sleeping person's hand into the water. Almost magically, the sleeping person begins to urinate against their will.

Now, my question is...WHY exactly does this happen? It's obviously some sort of biological response, but what response is it, and what purpose does it serve other than a way to get some laughs and make some enemies?

it is unbelievable how the US is using american tax dollars to pay teachers to teach evolution is truth when everything points to a creator. also how can people take the carbon 14 dating system for truth. scientists watched a seal die once. let it sit for 30 days and then preformed a carbon 14 test and it said it was thousands of years old. people use ur brains.

Now, before you go all wierd on me, I KNOW there is no such thing.
I was reading something from one of my friends, who is something of a conspiracy buff about "race-specific bioweapons", and although I know there is no such thing, I was wondering WHY?
I have a pretty good grasp of basic genetics, and was hoping somebody here can provide me with a somewhat technical explanation of why such things are the work of science fiction and not real science, so that the next time I see my friend, I can explain to her why she is being silly about this.
To all:
Thanks in advance for your time.

If the world's current human population is about 6 billion, I was just curious about approximately how many humans have ever lived, since the beginning of modern humans.

We talk about the 'five senses', though obviously we have many more than the usual sight, hearing, smell, touch, taste - we can sense the passage of time, heat, the position of our limbs, etc.

I read a list of over a dozen in a popular science book (perhaps 'Why Don't Penguins' Feet Freeze', or something like it); but I can't remember what was on the list.
