While scientifically-designed human organs may sound like science fiction, many labs across the world are hoping to one day make them reality.

Before an organ can be made in a lab however, researchers say there are two major hurdles to overcome.

The first is creating a biologically compatible 3D scaffold in which cells can grow. The second is triggering cells to grow into the desired organ or tissue.

The researcher's new approach uses a near infrared laser to trigger proteins to stick to a scaffold made from collagen.

The researchers were able to create any shape they wanted from the laser-created proteins.

A surgeon at the Hospital for Special Surgery in New York recently performed the first knee-replacement surgeries in the U.S. using augmented reality.

Jonathan Vigdorchik, M.D. , last month replaced the knees of two patients, who suffered severe arthritis in their knee joints, while using special glasses that enabled him to review crucial surgical data while performing the operations.

Augmented reality superimposes digital content, such as 3-D images or visual instructions, onto a user’s view of the real world through mobile devices and wearable headsets.

“At many time points during the operation it’s actually providing me information, making sure that my cuts are degree for degree, millimeter for millimeter, accurate,” Dr. Vigdorchik said.
