Are chicken nuggets grown from animal cells the ultimate innovation, or a flash in the pan? As Singapore allows the sale of cultivated chicken nuggets, Elizabeth Hotson speaks to Josh Tetrick, whose company Eat Just brought the innovative snack to market. Colin Buchan, executive chef at the exclusive club 1880 in Singapore, tells us what it's like to cook the nuggets, while two vegan friends in London talk about the ethics. Plus, the BBC's Regan Morris tells us why bringing lab grown meat to market in the US may be a tricky task, and Kelly Laudon, an attorney with law firm Jones Day takes us through the legal implications.
