Researchers from Yonsei University in South Korea have developed a beef cell-infused rice hybrid that could one day provide an alternative protein source for astronauts. Put simply, muscle and fat stem cells sourced from cows were transplanted into grains of rice, and due to the latter’s porous nature, there’s room for stem cells to grow within the grains in a petri dish.
After around 9-11 days, the hybrid food becomes a safe, usable ingredient that contains 8% more protein and 7% more fat than regular rice. The team claims that this beef-rice hybrid releases fewer greenhouse gases than if the same amount of protein was produced with traditional beef farming. Their goal is to one day create protein-enhanced foods such as this to help feed people in situations where food is hard to come by, whether it be from famines or space travel.

We usually obtain the protein we need from livestock, but livestock production consumes a lot of resources and water and releases a lot of greenhouse gas. I didn’t expect the cells to grow so well in the rice. Now I see a world of possibilities for this grain-based hybrid food. It could one day serve as food relief for famine, military ration, or even space food,” said Sohyeon Park, First Author of the Study.
