Astronauts need nutrition on longer space flights. One potential source? Their urine
Scientists are engineering yeast to use human urine and breath as a way to make omega-3 fatty acids to keep astronauts healthy during longer space flights.
You can’t get fresh salmon in space, but astronauts may one day be able to get the vital nutrients the fish provide — by recycling their urine and exhaled breaths.
Chemical engineers at Clemson University are bioengineering yeast to use human urine and breath to make omega-3 fatty acids, the vitamins humans need for heart, eye, and brain health that are found in fish such as salmon. It’s still in the
