Nano-robotic scalpel swarm shreds brain cancer cells from the inside

When it comes to fighting the deadly brain cancer known as glioblastoma, options are very much limited. This led a Canadian research team to take a novel approach. They tricked cancer cells into taking up carbon nanotubes, and they then shredded those cells by spinning the tubes using magnetic force. The treatment in mice shrunk tumor size and extended the rodents' lives, a finding that has the researchers hopeful for a similar result in humans.
