From the Inside


A new device developed by researchers at MIT is the latest weapon in the cancer-fighting arsenal, says New Scientist's Ferris Jabr. The tiny implantable tool can "track" the growth of a tumor from the inside — it's small enough to fit inside a needle and can be inserted during a regular biopsy, Jabr says. The small capsule is filled with magnetic nanoparticles containing monoclonal antibodies which can bind to molecules that indicate the presence of cancer. Doctors can use an MRI scan to "read" the device and detect the cancer-related molecules inside it, Jabr adds.
