Fascinating images from all parts of science!
Although my job is writing about science — putting it into words — there are times when images can say so much more than words. I am not much of a photographer or graphic artist, so most of these images were provided by other people, who are credited in the captions when I can remember who they were.

No, it's not Usain Bolt, it's Sam Whittingham, the first person to break 80 mph in a speedbike. Here (inside the capsule) he launches another attempt at the world record at Battle Mountain in 2004. On this try he went "only" 76 mph. See my article, "The cycling speed freaks of Battle Mountain" in the New Scientist.
