Researchers have used liquid metals to turn carbon dioxide back into solid coal, in a world-first breakthrough that could transform our approach to carbon capture and storage.
The research team led by RMIT University in Melbourne, Australia, have developed a new technique that can efficiently convert CO2 from a gas into solid particles of carbon.
Published in the journal Nature Communications, the research offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere.
Current technologies for carbon capture and storage focus on compressing CO2 into a liquid form, transporting it to a suitable site and injecting it underground.

DeBeers already sells artificial lab-grown diamonds for a fraction of the price of real ones. When you pay thousands for a diamond, it's not the stone that you're paying for, you're just paying for the knowledge that someone actually went and dug that shit out of the ground. Which is pretty fuckin stupid IMO, but apparently there are plenty of people who fall for it....

What's the fraction? Last time I even thought about buying a diamond was in the 1990s and the only option back then was Cubic Zirconia, which was tempting, but sort of lacked appeal in that I could easily afford a CZ so large and flashy that it was obviously 'fake'.
If I could have gotten a ~1 carat synthetic diamond in a good setting for under $1000, I would have gone for it. As it was, I think we got good 1/2 carat for ~$1600 and the good quality 1 carats were running around $5K. And the damn thing still fell out of its setting one day about 8 years later- luckily found it on the swimming pool deck.

Looks like the fraction is 2/15 -- $6k per carat for mined diamonds vs $800 for synthetic:

Figures they'd find my price point and use it. Put an $800 1 carat synthetic in a $200 setting and I'd call that a decent engagement ring.
The problem with a $1K engagement ring with CZ is that the stone can be arbitrarily large. I suppose you could just spend $300 on the CZ ring and take a $700 weekend vacation instead, that would be the rational thing to do.
