Stripping down science, the naked scientists.

The Naked Scientists. This week the naked scientists are traveling to the University of Oslo in Norway.

Awaiting you in the program, Dinosaur Dissections, Ultra-efficient solar cells,

new ways to combat cancer, mass extinctions, and...

You have sperm from, for instance, nematodes, small worms you don't want inside you,

which are maybe a couple of micrometers big to

Drusophila sperm reaching almost six centimeters.

Six centimeters but they're flies they're tiny flies. Yeah that's correct the sperm length is actually 10 times the length of the individual.

Thank goodness we're not flies.

Hello I'm Chris Smith and our first stop is the basement of the Oslo Natural History Museum

where Espin Knudsen is reassembling the remains of something you really wouldn't want to swim with.

If you think yourself a turtle maybe without the shell and you had a long neck to that

and sometimes a small head and sometimes a large head depending on what sort of police are we talking about.

And you basically have the police or body plan sort of laid out.

Were they vicious?

Some were. Most of the ones we have here from our locality at least are small-headed,

we're with very, I mean the head is probably about 30 centimetres long

and the teeth are very slender, to maybe 2 centimeters long and very

thin perhaps as half a centimeter or so in thickness and probably it mostly squids and small

fish. Then you have the large-headed pliosaurs,

which is another group of pleasesaws

that have heads up to maybe two and a half, three meters.
