In the last couple of years there’s been a bonanza in life sciences around something called CRISPR. This is a process that bacteria do naturally as a defense mechanism, but scientists have figured out how to use it to snip out specific genes from DNA and replace them. In other words, it makes cheaper and more precise genetic editing possible. Dr. Tim Townes, director of the UAB Stem Cell Institute, led a team that published a paper Thursday in Cell Reports on their use of CRISPR to develop a potential new cure for a troubling condition in children.
