...no, not on my writing, although you'll see what I've been working on ahead of time soon enough and I did start another short story today.
Progress on 3D printing and medicine. Somebody has managed to 3D print a network of small droplets that can flex like muscle or respond to neurons. It's not artificial tissue per se - but it can theoretically do the same thing.
This could be used, for example, to add muscle to prosthetics that responds much more like the real thing. They might be able to come up with a version that could replace a damaged liver. It also has properties potentially useful for drug delivery.
At the rate things are going we should seriously consider giving the Nobel Prize for Medicine to the inventors of the original 3D printer. Seriously.
