"Every year, in Germany alone, around 7000 people wait for a new cornea to save their eyesight. But donor corneas are in short supply. In an EU project, researchers have developed an artificial cornea which is to be clinically tested in early 2008."

The EU-funded CORNEA project has now developed an artificial cornea that is showing promise in trials. Reportedly, scientists at the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam and the Department of Ophthalmology at the University Hospital of Regensburg have created a device that is "based on a commercially available polymer which absorbs no water and allows no cells to grow on it." Put simply, the cornea implant can "firmly connect with the natural part of the cornea, while the center remains free of cells and therefore clear." Apparently, early versions have already been successfully placed in the eyes of rabbits, and if ongoing testing goes smoothly, they'll be headed for humans as early as next year.

Should men be able to give birth to children?


Joyce Nabuurs: To me this question seems to be a logical next step in the emancipation movement of the past century. More and more women entered the workspace, but the responsibility for pregnancy and childrearing remained female.
