You read right, researchers have successfully printed a 3D piece of beef steak. More than being able to print yourself a nice piece juicy steaks, the researchers were more interested in replicating the structure of the beef.  The cells were used to to produce muscle, fat and blood vessels which had to be arranged by hand in order to get the correct structure of the beef.

According to the article, which you can find here,  "The scientists hope proving that wagyu steak can be lab-grown gives hope for a more sustainable future where there are tasty alternatives to traditionally raised beef. Raising animals for food and other products contributes significantly to human greenhouse gas emissions, with cattle contributing more than all other animals combined, according to the Food and Agriculture Organization of the United Nations." 

The article continues, saying "Until recently, lab-grown meat hasn't had much structure to it. Instead, it has usually looked more like mince. However, the team believes that by improving the technology they're using, they will be able to not only produce the complex structures that define wagyu, but adjust for things like muscle and fat content."  

We are not too sure if the meat should actually be consumed by humans as yet, but we can safely say that this achievement goes a long way in the advancement of our healthcare capabilities. You can read the whole article by clicking here.
