Lander, already burned by blasts for minimizing the roles of Doudna and Charpentier in his “Heroes of CRISPR” article, apologized. “I was wrong to toast, and I’m sorry,” he wrote in a note to his Broad colleagues that he made public. “I reject his views as despicable. They have no place in science, which must welcome everyone.”
