Australian food startup creates world's first woolly mammoth meatball from lab-grown cells.

Australian food firm Vow has created a meatball made from the resurrected flesh of the long-extinct woolly mammoth, using the DNA sequence for mammoth myoglobin and filling in the missing gene links with the DNA of an elephant. The company hopes to phase out industrial meat production, which is damaging to the environment, and replace it with lab-grown meat that requires less land and water and produces fewer emissions. The woolly mammoth meatball will be displayed at the NEMO Science Museum in Amsterdam, but scientists are hesitant to try it due to the unknown effects on the immune system.
