The acronym CRISPR has become synonymous with editing DNA in recent years, taking center stage in the molecular geneticist’s toolbox as a means of identifying genetic codes and then cutting into them with uncanny precision. In its original function as a means of immunity in bacteria, the CRISPR/Cas (Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated endonuclease)

Our galaxy’s largest nearby companion is the Large Magellanic Cloud (LMC), a dwarf galaxy visible to the naked eye in the Southern Hemisphere. In recent years, new theoretical research and better observational capabilities have taught astronomers a great deal about our (not-so-little) neighbor. It’s becoming increasingly clear that the LMC is helping shape the Milky
