The second place photo [1] is absolutely amazing. It looks like galaxies in the universe, and the clear separation between the two populations bridged by axons show the incredible level of control humanity has gained over our world. We're not there yet, but this photo shows us how extremely well we're doing.
> A microfluidic device containing 300k networking neurons in 2 isolated populations. Both sides were treated with a unique virus and bridged by axons.
Probably studying axonal transport, the ability of some neuroinvasive viruses to spread from one neuron to the next via the axon & its connection to other cells.
