Scientists at Yale University have managed to fight inoperable brain cancer using a modified virus. The above picture shows the virus in green, invading the tumor cells in red. Mice that harbored various kinds of brain tumor, when treated with the virus, were completely tumor-free after three days. This is a very interesting, yet counter-intuitive idea and the dramatic results that it yields makes us hope that it can be applied to humans as well. The concept does have its drawback that the virus would infect the entire animal, and not just the tumor. Notwithstanding that, the results of this study are quite encouraging and could, we hope, improve the treatment options for human brain cancer.
