kambiz: City lights and neurons show striking similarities to in these side-by-side comparisons by Infinity Imagined. The city light photos were taken aboard the International Space Station, while the neuron images were created with fluorescence microscopy.
Here we see four nurse cells. Each red or green dot is an individual RNA molecule, which is produced from DNA (shown in blue). The RNA molecules intermingle on a threadlike network that allows them to move from one nurse cell to another and then into the developing egg (which we don't see in this image).
