Plug inElon Musk's latest project is Neuralink

So what's next for a billionaire after launching rockets and mass producing electric cars? If you're Elon Musk, the answer apparently is plugging computers into human brains. The Wall Street Journal reports his new venture, Neuralink, is working on "neural lace" technology that could allow us to upload and download our thoughts.

How can something this black be green?'Air-Ink' uses carbon soot to make ink

Start-up Graviky has created an exhaust filter that can pull 95% of the carbon soot from diesel exhausts, and then transform this into useable, purified, black ink or paint. The resulting ink matches regular sharpies and adds the smugness of knowing you've picked a greener option.
