Scientific rivalries are not uncommon. If in the 1950s, it was James Watson-Francis Crick team versus Rosalind Franklin, Craig Venter-Celera versus Francis Collis-Human Genome Project in the 1990s, in 2020, it is Jennifer Doudna versus Feng Zhang. This spat between two talented and remarkably intelligent researchers could be a multi-billion-dollar feud, and all in the name of a CRISPR technology. There are one technology and several takers, not to mention the patent battle.
