While science has been able to replicate these abilities with artificial skin, the colour changes are often only visible to the naked eye when the material is put under huge mechanical strain. (sciencedaily.com)
His lab is looking to see if other materials can show the same behavior and if mechanical strain can affect the superconducting properties of the material (these experiments were not carried out at temperatures where BaFe2As2 is a superconductor). (sciencedaily.com)
In the light of a review detailing the role of these genes in the cell shape changes leading to invagination, and of recent findings showing the expression of twist as mechanically sensitive, we suggest that the expression of twist in the mesoderm could alternatively be maintained by mechanical strains developed during mesoderm invagination.
