A new way to make powerful changes at will to the DNA of humans, other animals and plants, much like how a writer changes words in a story, could usher in a transformation in genetic medicine.
Scientists are not just excited about this recently discovered technique because it can snip and edit DNA with precision. It can also do the job more easily and cheaply than other gene-editing methods, making possible research that has historically been difficult, experts say.
Now some of the biologists who unlocked this tool, derived from the immune system of bacteria, are forming companies around it. Although this molecular system, known as Crispr, is not fully understood, researchers believe it can be harnessed to create therapies for intractable genetic diseases.
One of those scientists, UC Berkeley Professor Jennifer Doudna, was part of the team that in 2012 first demonstrated the technique. It is now employed by two companies she has co-founded: Caribou Biosciences in Berkeley, and Editas Medicine in Cambridge, Mass. The latter started last year with $43 million in venture capital. Another company, the aptly...
