Medical technology and practices have been advancing at an incredible rate over the past few decades, and one of the premier breakthroughs in the space is CRISPR. At a high level, CRISPR is a process that allows editing DNA sequences and gene function, which opens up a world of possibilities when it comes to developing new medicine and treatments. However, CRISPR as we know it today is not a perfectly precise tool, as it requires the rewrite of entire subsections of DNA or a genome. A new breakthrough in a joint study by Harvard and MIT has resulted in a new process called base editing, which gives researchers the ability to edit minute portions of DNA. In other words, if a single word needed changing in a paragraph, CRISPR would require rewriting the entire paragraph with one word changed while base editing would allow changing the specific word itself.
