Individual Vertex Bone Weighting
Individual vertex bone weighting is a method of bone weighting - applying a weight to the bones used in model animation, such that they actually have weight in the virtual environment ? which applies the weighting to the vertexes where bones meet rather than to the bones themselves. The net result is that deformations occur most strongly at the joints, crinkling the outer avatar mesh the most at these points ? exactly as occurs in organic forms.

Usually, creation of a prosthetic limb errs on the lighter side, sacrificing capability for lightness. This is because until now, it has not been possible to examine the surviving bone in enough detail to safely screw a prosthetic into the bone.
One of the most important aspects when working with any skeletal system, is the joint where bones connect. If you don't get this area right, then bone will grind against prosthesis, and the bone is likely to take critical damage first. You inflame a joint, that did not have a problem in the first place, and spread further complications throughout the body.
Pennsylvania State University researcher Henry J. Donahue, Professor of Orthopaedics and Rehabilitation, Penn State College of Medicine, has found a use for the inorganic material hydroxyapatite, in covering sterilized implants so that they form a natural bond with on-site bone, fusing together over time.
Usually with imaging of the inner workings of the brain, we cannot get down as far as the individual neurons. That's a pity because if we could image individual neurons during the firing process, it would add another tool into our toolkit for working out at a fine level, exactly how neurons are assigned into functions.
The following clip from Onion News Network, is an obvious spoof - its all that onion ever produce, but at the same time, this one may cut closer to the bone than perhaps we would like.
A much more in-depth look at the concept of designing multiple implants inside the body, so you can guarantee they will always connect perfectly, as demonstrated by the prototype LayerWise jaw and its successive implants.
A Belgian German Shepard dog called Storm, has become the first person to be fitted with a prosthetic implant which fits into the bone and sticks through the skin with no risk of infection to the animal.
