A new experiment has raised medical and ethical questions as serious as those surrounding human gene editing: A support system delivering artificial blood to pig brains prevented degradation of important neural functions, Yale researchers discovered.
The Chinese scientist who sparked an international outcry after alleging to have helped create the world's first genetically edited babies has raised the possibility of a third child being born, after announcing that a separate woman was pregnant at an early stage with a modified embryo.
Researchers in China say they've bred healthy mice with two mothers using a new type of gene editing technology, a significant feat that may help researchers better understand mammalian reproduction but carries significant ethical and safety questions.
Researchers have rendered a population of mosquitoes in a lab sterile using the gene-editing tool CRISPR-Cas9 by homing in on a specific target in insect DNA -- the doublesex gene -- raising the possibility of eradicating disease-carrying species of the insect entirely, according to a new study published Monday in Nature Biotechnology.
