CRISPR-Cas9

The genome editing technique known as CRISPR-Cas9 is changing many fields in biology with its precision and simplicity. Here's what you need to know.
Dairy cows have to be dehorned by farmers in a cruel fashion, but its necessary to protect other cows and the farmers that handle them. One scientists, however, is working on a solution: incorporating the genes of from a hornless cow into the regular dairy cow. The technique promises to reduce animal cruelty, but since its a GMO, advocates don't like it.
Researchers from MIT and the University of California are arguing over who owns the patent for the genome editing technique CRISPR-Cas9. Both teams make interesting cases and whoever is awarded the patent stands to make billions from the techniques limitless potential.
