Picture Wednesday: Bunny nematoda and other colours | Day 249

Microscopy can get down to incredible detail these days, but if you add false colour, it also gets incredibly interesting to look at – and highlights detail you would otherwise overlook.

Take this male nematoda, for example. It’s basically a worm, but just look at those stunning bunny ears!

Then there are these strings of Ebola virus, emerging from an infected cell. Without colour, it would all just look like a bit of a jumble.

In this cross-section of tissue from a fruit fly, the green-coloured tracheal cells which transport oxygen are shown weaving their way throughout muscle tissue, coloured red. You need that kind of contrast to really appreciate the fine branching of the cells.
