Scientists Simulate Seashells’ Structures

*Scientists have successfully created synthetic crystals whose structures and properties mimic those of naturally-occurring biominerals such as seashells.*

*The findings, published in the journal Nature Materials, could be an important step in the development of high-performance materials, which could be manufactured under environmentally-friendly conditions.*

Professor Stephen Eichhorn, who has just moved to the University of Exeter from the University of Manchester, played a key role in the research. Professor Eichhorn has been appointed to a Chair in Functional Materials, through the University of Exeter’s £230 million investment in science, medicine and engineering. Exeter’s vision is for a multidisciplinary and interdisciplinary approach to the understanding and application of functional materials – from fundamentals to manufacture – exploiting world-leading materials knowledge to deliver new concepts, processes and products.

*Berkeley Lab Researchers Show How Loss of Bone Quality Also a Major Factor*

It is a well-established fact that as we grow older our bones become more brittle and prone to fracturing. It is also well established that loss of mass is a major reason for older bones fracturing more readily than younger bones, hence medical treatments have focused on slowing down this loss. However, new research from scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) shows that at microscopic dimensions, the age-related loss of bone quality can be every bit as important as the loss of quantity in the susceptibility of bone to fracturing.
