Researchers in Germany have zeroed in on a new cancer-fighting tool: magnetic sperm.

Scientists at the Leibniz Institute for Solid State and Materials Research found that when sperm carrying a common chemotherapy drug were outfitted with what New Scientist described as "tiny, four-armed magnetic harnesses" and released near cervical cancer cells, the supercharged swimmers were able to eliminate 87 percent of the malignant cells they encountered in just three days. The harnesses "allowed [the sperm] to be guided by magnets," New Scientist explained, and thus more effectively reach the cancerous cells and deliver the medication.
