Show Notes

Scientists have found a way to make organisms not need food at all. Bacteria usually rely on some sort of sugar to survive, but a group at the Weizmann Institute of Science in Israel made a population of a common bacteria able to feed on carbon dioxide, very much like plants do. They did this by genetically modifying how the bacteria digests its food, and then putting them in a tank with very little food - sugar - and a lot of carbon dioxide. In only a few hundred generations, these bacteria evolved to feed on the carbon dioxide in the air instead. Amalia Thomas reports... Like this podcast?
