Inspired by the growth of bones in the skeleton, researchers at the universities of Linköping in Sweden and Okayama in Japan have developed a combination of materials that can morph into various shapes before hardening. The material is initially soft, but later hardens through a bone development process that uses the same materials found in the...
LINKÖPING UNIVERSITY IMAGE: THE BLACK MATERIAL IS AN ELECTROACTIVE POLYMER, THE VOLUME OF WHICH CHANGES WHEN THE RESEARCHERS APPLY A LOW VOLTAGE, WHICH MAKES THIS SIMPLE “MICROROBOT” BEND. ON THE OTHER SIDE OF THE MATERIAL, YOU CAN SEE THE GEL TO WHICH THE RESEARCHERS HAVE ATTACHED BIOMOLECULES THAT ALLOW THE SOFT GEL MATERIAL TO HARDEN...
In a paper published in the journal Nature, an international research team led by researchers at Karolinska Institutet in Sweden reports that bone growth in mice takes place in accordance with the same principles as when new cells are produced in blood, skin and other tissue. This contradicts the previous understanding that bone growth depends...
