Maybe It Won't Be The Machines That Kill Us After All

“Human astrocytes certainly inspired the mice. Their neurons did indeed build stronger synapses. (Perhaps this was because human astrocytes signal three times faster than mouse astrocytes do.) Mouse learning sharpened, too. On the first try, for instance, altered mice perceived the connection between a noise and an electric shock (a standard learning test in mouse research). Normal mice need a few repetitions to get the idea. Memories of the doctored mice were better too: they remembered mazes, object locations, and the shock lessons longer.”
 — Scientists at the University of Rochester Medical Center implanted human brain cells into the brains of baby mice and the mice turned out smarter than other mice. I am continually amazed at how few scientists seem to have seen Deep Bue Sea.
