Bioengineer Morris Benjaminson is figuring out how to create fish on demand, to develop a device that would grow fresh flesh aboard a space ship to feed astronauts.



The researchers cut chunks of muscle from oversized goldfish into pan-sized pieces. They worked quickly to keep the flesh alive. “The fish is dead, but the tissue isn’t,” Benjaminson explains. The chunks were washed in alcohol and stuck in a vat of fetal bovine serum, a nutrient extracted from the blood of unborn calves. After a week, the fish chunks had grown by 14 percent.
