Cancer-fighting bacteria, and ChatGPT in the classroom
The news: There are trillions of microbes living in and on our bodies—and we might be able to modify them to help us treat diseases. Scientists have altered the genomes of some of these bacteria, essentially engineering microbes that can prevent or treat cancer. How they did it: The team chose a microbe that’s commonly found on human skin and modified it by inserting a new gene that codes for a protein that sits on the surface of some cancer cells. They applied it to heads of mice injected with skin cancer cells, and…
