The interface between the hydrogel (left-hand side) and the PDMS (on the right-hand side). Engineers have developed a new material that mimics human cartilage—the body's shock absorbing and lubrication system, and it could herald the development of a new generation of lightweight bearings. Cartilage is a soft fibrous tissue found around joints which provides protection from the compressive loading generated by walking, running or lifting. It also provides a protective, lubricating layer allowing bones to pass over one another in a frictionless way. For years, scientists have been trying to create a synthetic material with the properties of cartilage....

Bearing sons 'can shorten mother's life' By Roger Highfield, Science Editor (Filed: 02/11/2005) Giving birth to and raising several sons could be bad for the long-term health of mothers but good for fathers, according to a study published today. Scientists suspect that having large families shortens a parent's lifespan, because the effects of reproduction and childcare can take their toll on health. However, in a society without good health care, sons could be especially costly for the mother for several reasons. They are, on average, born heavier and place more physical stresses on the body. They also raise levels of...
