TL;DR

Dr. Kongri Jin is pioneering regolith-based living bricks using bacteria and fungi to craft Martian structures self-sufficiently.

Transcript

when we go to Mars we're going to need to build things roads buildings landing pads things like that and obviously you don't want to bring all of the raw materials from Earth you want to make some of that stuff on site and so what you've got to work with right you've got the regolith and you've got the atmosphere and energy coming from the Sun and ...
