...Hold pen/pencil between the first and second knuckles of your index and middle fingers. By using your middle finger as the fulcrum and placing your index finger slightly towards the butt end of your pen/pencil, force the non-writing end of the pen/pencil against the webbing between your thumb and index finger. Maintaining this pressure, straighten your fingers slightly, whipping the non-writing end around in a clockwise fashion. Now you can twirl anything...

FLESH AND BONES. Treating bone cells right is what Charles Vacanti, an anesthesiologist and director of the Center for Tissue Engineering, has been doing at the University of Massachusetts Medical Center in Worcester. When that machinist lopped off the top of his thumb, Vacanti took some of the victim's bone cells, grew them in the lab and then injected them into a piece of coral fashioned into the shape of the missing digit. "Coral's got lots of interconnected channels for the bone cells to grow in," says Vacanti. It also degrades as bone replaces it. The patch...
Moving from the thumb to other hand parts, Charles' brother Joseph Vacanti, a transplant surgeon and tissue-engineering pioneer in his own right, has grown human-shaped fingers on the back of a mouse, demonstrating that different cell types can grow together. He and colleagues at Boston's Massachusetts General Hospital shaped a polymer to resemble the end and middle finger bones. These shapes were seeded with bone, cartilage and tendon cells from a cow. Then the medical team assembled the pieces under the skin of the mouse--"just like you'd assemble the parts of a model airplane," says...
