Using Gene Editing to Transform Cancer

 

You may have heard of the gene-editing technique CRISPR-cas9, often simply called CRISPR. Introduced in 2012, CRISPR works like a pair of scissors to cut DNA, inserting or reordering bits of genetic code with remarkable, science-fiction-like results: CRISPR can help create mosquitoes that don’t transmit malaria, or be used to breed unusually muscular beagles, or even create mini pigs. In humans, the technology is being tested to battle cancer — by removing patients’ immune cells, editing them, and reinserting the weaponized cells into the body to hunt cancer.

New protein discovery could change biotech forever

The quest started with trying to make better yogurt.

Bacteria that uses a tiny molecular machine to kill attacking viruses could change the way that scientists edit the DNA of plants, animals and fungi, revolutionizing genetic engineering. The protein, called Cas9, is quite simply a way to more accurately cut a piece of DNA.
