Blood vessels incorporated into 3D-printed living skin
It certainly would be great if instead of having to be harvested from a patient's own body, permanent skin grafts could be 3D-printed as needed. Well, we may be getting a little closer to that point, as scientists have now bioprinted living skin comp
Ancient Maya Farms Revealed by Laser Scanning
That all changed when scientists began using lidar, a remote sensing technique that shoots lasers from low-flying planes. By measuring a laser's travel time, scientists can determine the shape of the ground within a few centimeters and create a pic
Fiber optics
Fiber-optic cables send light signals down a glass or plastic fiber thinner than a strand of hair. Reflective cladding surrounding that core boosts the signal in a technique called "total internal reflection." The speed of the light passing down
