The world’s first lab-grown steak has been created – and it’s just as tender (嫩的) and juicy as the real thing. Israeli company Aleph Farms created the 3D-printed steak with cow cells (细胞). They didn’t have to kill any cows to make it. Scientists took cells from two cows, grew them in a lab, and pieced them together to form a steak. Four different cells were created – support cells, fat cells, blood vessel (血管) cells and muscle cells. They then became the “ink” in a 3D printer. The company believes its new method is a major leap (飞跃) forward towards its dream of creating “a more sustainable (可持续的) world”.
