Excellent issue. The SpaceX’s Raptor engine…this is something that anyone can geek out on.

Just look photos of this engine! Raptor 1, btw, was the most advance engine…possible the most advanced machine…built by humankind. We are already on version 3 which looks so slick and simplified that its hard to believe it works.

That is why Tory Bruno, himself a smart guy, couldn’t believe it was actually a complete engine.

We shouldn’t be surprised, human progress is all about doing more with less. More output with less energy and fewer atoms!

I will be posting this one on my Facebook page as well: https://www.facebook.com/profile.php?id=61563015572000

Another great roundup. I've got to he honest I come here for the space and computer science type stuff because that's my area of interest. However the first section about brain-computer interfaces really struck me.

"New research using functional MRI scans and EEGs showed that about 25% of patients unresponsive due to brain injury are actually conscious."

This is crazy and a thought I find utterly terrifying. Being "locked in" scares me more than death. It must be horrific. Anything we can do to help these people is amazing.

Thanks Alex! I really appreciate it.

Agreed, I think being 'locked in' will soon be a thing of the past thankfully. Can't come soon enough.
