yeah, you read that right, a recent study has found that ice crystal nuclei* of bacterial origin are the most efficient seed crystals for making the clouds that give us rain.
am i the only person who thinks that is flat out weird?
bacteria make bits of stuff that are an excellent substrate on which to grow ice crystals for the purpose of forming clouds.
* nuclei here refers to the center bits of ice, not the genome-holding center bit of a cell. bacteria don't have nuclei, if i remember my high school biology correctly.
