Five Animal Products Scientists Can Now Grow In a Lab

The production of animal products for human consumption has ethical ramifications, such as needless animal suffering and polluting factory farms. Scientists in London have created a burger made from meat that was grown in a lab, from bovine stem cells.

In vitro meat might be the most well-known example of a post-animal foodscape, but it's not the only example. Scientists are working to recreate animal-based products—from milk to cheese to fish, even leather—in a lab.

An in vitro burger has been created but it could take up to 20 years for in vitro meat
to become a commercially viable option for everyone.

Synthetically made cow DNA is injected into yeast, so that it produces casein,
a protein found in cows' milk. Then, the engineers take the casein, mix it with water, vegetable butter and vegan sugar (no lactose). This is still in the research stage
