Amsterdam’s NEMO Science Museum unveils a giant meatball made from cultivated woolly mammoth flesh. Created to spark conversations about sustainable meat alternatives, food engineers from the Australian cultured meat company Vow inserted sheep cells with the mammoth myoglobin gene. “When it comes to meat, myoglobin is responsible for the aroma, the colour and the taste,” James Ryall, Vow’s Chief Scientific Officer explains. Where Vow’s mammoth DNA sequence had gaps, African elephant DNA was spliced in for completion.
