Time again for five interesting things: stuff you should know, stuff you might want to take action about, stuff you can share.

Flower power: Ever heard of phyto-mining? Or Phyto-remediation? It’s the process of using plants to extract things from the soil. New Scientist is reporting on an Albania start up farming plants to harvest carbon-neutral nickel from the soil while simultaneously removing carbon dioxide from the atmosphere.

Long distance repair: NASA successfully fixed Voyager 1… at a distance of 15 billion miles from Earth. If only service reps in my city were as good…

Should we call them chippers … instead of choppers? Quiet, electric helicopters are here at long last.

Steppe right up: Proof we can fix things when we try. The rare Przewalski’s Horse has returned to Kazakhstan, thanks to an initiative by the Prague Zoo to reintroduce the animal.

Mmmm: Healthier, more sustainable chocolate? Yes please!
