Time to add another superpower to insect silk, which already includes bulletproof skin and implantable microelectronics. Recent research indicates that silk may be an ideal candidate for creating strong, flexible scaffolding for re-growing bones. Scientists used a chemical process to break silk strands down into nano-scale fibers that were used to reinforce a silk protein scaffold. By mimicking the natural roughness and stiffness of bone, this biodegradable structure helps to encourage vigorous bone growth. While certain biomaterials are at the center of research into bone regeneration, few of these existing materials can match silk's toughness, especially in load-bearing grafts.
Regrowing Bones with Silk
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.Comment
