Cancer survival rates could be greatly improved if scientists are successful in developing microscopic medical weapons that obliterate cancerous cells. Nanomachines may be tiny – 50,000 of them would fit across the diameter of a human hair – but they have the potential to pack a mighty punch in the fight against cancer.
The US Food and Drug Administration approved a new leukemia treatment, which the agency considers the first gene therapy it has cleared to hit the market in the United States. The treatment, called Kymriah, aims to give some patients a second chance after first-line drugs have failed. This may happen in up to a fifth of patients, according to the FDA.
