3D printers have been used to create bone-like material which researchers say could aid in repairing injuries. The new material would act like scaffolding, promoting the growth of new cells and then dissolve away with no ill-effects. Professor Susmita Bose, who helped carry out the work at Washington State University, has been at work on the material for four years. A breakthrough came recently when she found a way to double the strength of the main ceramic powder—calcium phosphate—by adding silica and zinc oxide.
What’s the Big Idea?
Within just a few years, doctors could use the printing technique to custom-order replacement of bone tissue. “Tests carried on immature foetal bone cells in the laboratory found that new bone cells started growing over the scaffold within the first week of it being attached.” Dr. Bose predicts that within a decade or two, doctors will be able use artificial bone from 3D printers as scaffolds, along with bone growth factors, to repair anything from a broken jaw to a broken spine.
Eyes with lower pigment (blue or grey eyes) don’t need to absorb as much light as brown or dark eyes before this information reaches the retinal cells. This might provide light-eyed people with some resilience to SAD.
