When a heart gets damaged, such as during a major heart attack, there's no easy fix. But scientists working on a way to repair the vital organ have now engineered tissue that closely mimics natural heart muscle that beats, not only in a lab dish but also when implanted into animals.

Studying epithelial cells, the cell type that most commonly turns cancerous, Johns Hopkins researchers have identified a protein that causes cells to release from their neighbors and migrate away from healthy mammary, or breast, tissue in mice. They also found that deletion of a cellular 'Velcro protein' does not cause the single-celled migration expected. Their results, they say, help clarify the molecular changes required for cancer cells to metastasize.

From genetic and genomic testing to new techniques in human assisted reproduction, various technologies are providing parents with more of a say about the children they have and 'stirring the pot of designer baby concerns', writes Thomas H. Murray, President Emeritus of The Hastings Center, in a commentary in Science.
