This is not a photograph of a reptile's skin. Can you figure out what it is?
This incredible image was captured using a scanning electron microscope. It's been colorized to provide contrast, but this is actually what it would look like if you balanced one red blood cell on a pin. Amazing.
This is the first ever scanning electron microscope image of a strand of DNA, and it shows the structure of the minuscule string of molecules that encodes all life.
These bugs might just be the hardest organisms on the planet. They're the only creatures observed alive inside an electron microscope that actually survived this airless, high-radiation environment. This discovery could mean big things for life on other worlds.
Biological flying machine? Terrifying monster of the deep? Nope - this is just a scanning electron microscopy image of a Lamnacarus ornatus, or common mite.
