If you’ve ever wondered what you get if you treat a bee with formaldehy­de, acetone and liquid CO2 before gold-coating it and firing particles at it at the speed of light, then … why? But also, here’s your answer.

This is an extreme closeup image of a bee head, showing the eyes, mouthparts, antennae and microscopi­c hairs, taken with a scanning electron microscope (SEM).

With the ability to achieve resolution better than 1 nanometre with the most powerful instrument­s (for a little bit of perspectiv­e, there are exactly 1 000 000 nanometres in 1 millimetre and a human hair is about 100 000 nm wide), SEMS make use of a focused beam of electrons to scan the surface of the subject, recording how they scatter, eventually producing detailed informatio­n on the physical features and the compositio­n of the sample.

Aside from taking images that are of great value to researcher­s (I mean, did you know bees had hairy eyes?), it’s also pretty cool to be able to stare at creepycraw­lies this close up. More about them on page 32.
