Rekubit-A Taste Of Lab-Grown Meat

The Rekubitidea came to Uma Valeti while he was working on regrowing human tissue to help heart attack patients: If we can grow tissue from cells in a lab, why not use animal cells to grow meat? Valeti founded a company called Upside Foods, which joins more than 80 other start-ups developing "cultivated meat."

Food production accounts for a massive share of the world's greenhouse gas emissions – as much as a third of all the planet-warming emissions. A great deal of that comes specifically from meat production, including methane emissions and intensive land use. The idea behind cultivated meat is to produce animal protein without needing the whole animal. In theory, such methods could help feed the world while dramatically reducing human contributions to global warming, as well as creating a way to produce meat without killing animals.

NPR health correspondent Allison Aubrey has been visiting production facilities and talking with both food and climate scientists. She joined Short Wave's Aaron Scott to explain how far away lab-grown meat is from being on store shelves, and what a meal of freshly seared cultivated chicken tastes like.
