The "first man-made biological leaf" could enable humans to colonise space

RCA graduate Julian Melchiorri says the synthetic biological leaf he developed, which absorbs water and carbon dioxide to produce oxygen just like a plant, could enable long-distance space travel.

"Plants don't grow in zero gravity," explains Melchiorri. "NASA is researching different ways to produce oxygen for long-distance space journeys to let us live in space. This material could allow us t0 explore space much further than we can now."
