Sugar could help repair artificial human joints

A sugar-containing polymer coating could one day help repair artificial joint implants, like hip replacements, when they are damaged through wear and tear, according to new research.

Manufacturing stem cells in a bioreactor

With the aid of artificial stem cells, it will soon be possible to establish new treatments for previously incurable diseases such as Alzheimer's disease. At the Fraunhofer Project Center for Stem Cell Process Engineering ...
