They'd looked at dental calculus under a microscope, and what they had found was things like pollen and plant starches, and they'd found muscle cells from animal meats and bacteria.

They lay their eggs in it, thinking it's a nice bit of carrion, and not realizing that there's no food for the eggs, that the eggs are going to die, but the plant, meanwhile, has benefited, because the bristles release and the flies disappear to pollinate the next flower fantastic.

To the right species of bee, this looks like another very aggressive bee, and it goes and bonks it on the head lots and lots of times to try and drive it away, and, of course, covers itself with pollen.

Because you have to chuck out masses and masses of it, hoping that your sex cells, your male sex cells, which are held within the pollen, will somehow reach another flower just by chance.

And if you look down into it, there's this sort of dam past the spadix, flies get attracted by the heat which is boiling off volatile chemicals, little midges and they get trapped underneath in this container.

Most pollen that causes hay fever for us is from plants that use the wind to disseminate the pollen, and that's a very inefficient process, which is why it gets up our noses so much.

Community tools, like text messaging, that can tell you when pollen counts are up or smog levels are rising or a natural disaster is unfolding, can give you the information you need to act in a timely fashion.

And when the insect gets there and lands on it, dousing itself in pollen, of course, that it's going to take to another plant, if you look at the every home should have one scanning electron microscope picture, you can see that there are actually some patterning there, which is three dimensional.
