Degradation of magnesium implants in bone: mechanisms of Mg storage and impact on bone structure

degAdvanced X-ray microbeam techniques at the ESRF have enabled a team of Austrian researchers to study the reaction of bone to biodegradable bone implants based on Mg. The study unveiled an impact of the implant degradation speed on the Mg distribution, indicating at least two different pathways of Mg storage in bone. Changes in bone nanostructure and mineralisation were observed in a region of high local Mg content. The results suggest direct incorporation of Mg in bone mineral crystals.

Jay’s plumage opens path to everlasting colour

esrf-1.jpgScientists from the University of Sheffield have used the ESRF’s X-rays to study the blue and white feathers of the Jay and have found that birds use well-controlled changes to the nanostructure of their feathers to create the vivid colours of their plumage. This research opens new possibilities for creating non-fading, synthetic colours for paints and clothing.
