You've never seen a snowflake,free knocked up sex videos search table salt, or the head of a tick this close up.
The winners of the 47th Nikon Small World Photomicrography Competition have been announced, with the top prize awarded to the Baylor College of Medicine's Jason Kirk for his close-up image of a southern live oak leaf.
Stacking together 200 individual images of the leaf, Kirk used a custom-made microscope system and edited the colour temperature and hue in post-production. Those white tentacle looking things are trichomes (which protect the plant against extreme weather), the purple parts are the stomata (which regulate gases), and the bits in cyan are vessels (which guide water through the plant).

"The lighting side of it was complicated,” said Kirk in a press statement. "Microscope objectives are small and have a very shallow depth of focus. I couldn’t just stick a giant light next to the microscope and have the lighting be directional. It would be like trying to light the head of a pin with a light source that's the size of your head. Nearly impossible.”
