The latest episode of the Listen To The Signal podcast is up!

Listen to the new episode “Robot Brains From Outer Space” now!

So this month I was reading this article in the New York Times (, and had that moment, you know, where fact can be stranger than fiction. Apparently scientists have been growing brain organoids for a while – taking human stem cells and cultivating little clusters of neurons, to help with brain disease research. At some point someone raised the ethical question, “what if we grow a brain that gains consciousness?” But everyone pooh-poohed that idea, I mean, come on, it’s just a cluster of cells, right? Well, they shot a bunch of these organoids into space, aboard the International Space Station, to see how they’d grow there, and even hooked some up to a robot. And then they started seeing brain wave activity, similar to that of retrieving memories and dreaming, at the level of a developing premature baby. I’m not kidding. So this is a horror story waiting to happen, right? Let’s see what happens… P.S.
