Scientists have cracked 3D printing tungsten carbide-one of the hardest metals on Earth. In my novels, Joe Ballen is chief engineer on a 3D printed O'Neill cylinder. Two centuries later, habitats like it are standard across dozens of star systems. Turns out the future I've been writing is arriving ahead of schedule — again. https://tinyurl.com/3dpmetal #science #engineering #sciencefiction #scifi

Cosmic voids may be driving the universe's expansion through dark energy. Even emptiness has power. Funny, I've been thinking about voids a lot recently. My novel "A Crimson Void" is out this spring. #science #space #scifi #writing #cosmology ziply.pk/cosmicvoids

The route Draeger is expected to follow in A Crimson Void... he doesn't. This is from the 3D starmap I built to accompany the books. Join my newsletter for a chance to name a star in it. https://davidmkelly.com/a-crimson-void/ #SciFi #Scie… ★ 3

Some men are defined by a single decision made in the heat of the moment. For Draeger, it cost him his career, his freedom, and three years of his life - and now someone desperate enough is handing him command of an obsolete ship, a missio… ★ 3

Targeted microbes to fight gum disease without killing beneficial bacteria? My Joe Ballen novels have a similar nanomite tooth scrubber called DentiKleen. Should I be worried my dentist is now living in my fiction? 🙂 #SciFi #science #healt… ★ 3

Researchers propose a bold twist to dark matter. It may not be a single particle at all, but a mix of two different ones that interact with each other to produce detectable signals. #science #physics #astrophysics https://www.sciencedaily… ★ 2

In 2013 I wrote a cyborg character in "The Three Lives of Mary" (https://viewbook.at/TLOM) who could reverse her joints so she never had to turn around. Boston Dynamics just built exactly that. Amazing to see reality catching up! #SciFi #w… ★ 4
