The lubricant that forms to lessen friction in metal-on-metal hip replacements is made of a thin, graphitelike layer of carbon, not protein as researchers suspected (Science, DOI: 10.1126/science.1213902). That surprise might pave the way for long-lasting implants.

Ball-and-socket-shaped hip prostheses can be made from several different materials, including metal, plastic, and ceramics. The types thought to wear the least with time are metal-on-metal implants, with both ball . . .
