Lego Used to Create Artificial Bones of the Day

Cambridge University researchers studying artificial bones have found a unique way to automate the repetitive process of creating samples: they used Lego Mindstorms. Creating a bone sample involves dipping it into a calcium and protein bath, rinsing it in water, and then dipping it into a mixture of phosphate and protein. The process needs to be repeated so many times that it's impractical for a human to do
