The invention of the powerful gene-editing technique CRISPR is a game-changer for genetic engineering, making the removal or insertion of DNA sequences relatively easy and inexpensive. The key paper outlining how it works was published in 2012, but already scientists are eagerly exploiting its therapeutic and commercial potential, from modifying yeast cells to human embryos.
Abstract:
Gene editing promises to enable the safe use of pig organs to transplant into humans. Who could object to that?
