Bioprinting 3D printing of organs is becoming more and more a reality with researchers fine tuning the process. Scientists are presently trying to tackle the best ways to print a wide range of tissue & cells types. Bone appears to print & grow best within a hydrogel scaffold. Cartilage, on the other hand, appears to grow best just on its own without a scaffold.
Imagine how wonderful it will be when doctors will be able to order new printable organs for transplants surgeries
Squishy robot? Yes, please! Dubbed "octobot" by Harvard scientists Robert Wood, Ph.D., and Jennifer Lewis, Sc.D who invented it, this squishy autonomous robot is completely composed of soft materials. While previous efforts have made robots with soft external features, this is the first robot to have its control system and power source untethered by cables and composed of a chemical fuel (aqueous solution of hydrogen peroxide!)-mediated fluidic circuit housed within silicone
