And the conventional way of injecting DNA sequences into the nucleus of an egg is using a hollow needle to pump DNA-filled liquid inside of it. (But eggs aren't really designed for this, and about 40 percent of the time, they explode.) Needless to say, after exploding, they're not really capable of contributing to science.
Researchers from Brigham Young University have a better way, and it's the system in the picture above: a nanoscopic framework that can hold one single egg, while an even more nanoscopic injector needle stabs it.
