implantation

"Rather than ion implantation, molecular beam epitaxy was used to precisely incorporate gallium atoms into the germanium's crystal lattice," says Julian Steele, a physicist at the University of Queensland and a co-author of the study.

Four to five weeks after implantation of the chip in one eye, patients began using the glasses.

They had two options – either have a version of IVF whereby the embryo is tested for the gene before implantation, or conceive naturally and have the developing embryo tested.

Three deaths occurred in the group with reconditioned pacemakers, but none were related to the implantation procedure, device infection or malfunction.

Their findings, published in Developmental Science, show that a higher proportion of shape-based nouns in a child's vocabulary shortly after cochlear implantation was associated with better language development for the next three years.
