So this is an amazing thing we talked about in bio the other day. It’s a method called Brainbow. It’s really hard to track neurons when they can get so long and tangly, as you can see in this light microscopy of a mouse hippocampus, so scientists can mark each neuron with a different color of fluorescence via transgenes that produce fluorescent proteins. What a brilliant solution!
Rainbow Eucalyptus, is the only species of eucalyptus that grows in the northern hemisphere and is normally grown for its pulpwood, used to create white paper. But why does it look like it’s been painted? The secret behind the Rainbow Eucalyptus is that the trees shed multiple patches of bark every year, but not at the same time. As the patches are gone, the green inner bark is exposed, and as it matures it turns bluish, then orange, purple and maroon. This creates the rainbow effect.
how is something like this real.
