It’s still in the early stages, but scientists are wondering if they might have just found a cure for cancer. And alike many more amazing scientific discoveries, it was all a bit by accident. While looking for a way to protect pregnant women from malaria, Danish researchers found that armed malaria proteins can attack and revert cancerous cells to healthy tissue. The potential cure combines a bit of protein from the malaria vaccine with a toxin that can enter cancer cells and kill them off. In lab testing, the process has proven effective against 90% of cancers. So far the successful testing has been done in cells and on mice, but researchers hope to start clinical testing on humans in the next four years.
