Fix us better

A big area of interest in science and technology are ways in which both can lead to improvements in artificial limb and tissue replacement for wounded individuals.  This week Eric Bland, from Discovery News, wrote two interesting articles on research in the field of artificial tissue creation/replacement.  The first one deals with artificial muscles that can heal themselves and store extra energy.  The second article concerns hydrogel which could someday be used as artificial cartilage in joints.
