Current body protheses do not last more than 10-15 years. After this time, the operation has to be repeated in order to change prothesis. It is usually problematic as, in general, it is elderly people that use the procedure. Researcher Nere Garmendia, based in the Basque city of Donostia-San Sebastian, has just published her Ph.D., a thesis which may well mean the first step to solving this problem.

 | A "metal foam" that has a similar elasticity to bone could mean a new generation of biomedical implants that would avoid bone rejection that often results from more rigid implant materials, such as titanium. Researchers at North Carolina State University have developed the metal foam, which is even lighter than solid aluminum and can be made of 100 percent steel or a combination of steel and aluminum. ...> Full Article |
A team of University of Wisconsin-Madison researchers has created the strongest form of collagen known to science, a stable alternative to human collagen that could one day be used to treat arthritis and other conditions that result from collagen defects.

By tailoring peptide amphiphiles, small synthetic molecules developed at Northwestern University, and combining them with other molecules, Northwestern researchers can make a wide variety of structures that may provide new treatments for medical issues including spinal cord injuries, diabetes and Parkinson's disease. Combining the PA molecules with hyaluronic acid, a biopolymer found in the human body in places like joints and cartilage, resulted in an instant membrane structure in the form of self-assembling sacs.
