biology stories

 
There's still an awful lot that's not understood about how complex biological systems (like our bodies) really work. Part of the problem is that we can't just go look, since the only way to really see inside a brain (for example) is to cut it open, which by definition destroys its structure. Japanese scientists have a better idea: just turn everything transparent.
 
This petri dish contains an artificial brain consisting of about 60 rat neurons. It's not much, but that doesn't stop the brain from having about 12 seconds worth of working memory, which is probably just long enough for it to start wondering what the heck it's doing in a petri dish anyway.
