Nano-tool

A platinum fiddle that's just 35 microns in length and 13 microns in width is believed to be the world's smallest violin, measuring just a fraction of a microscopic tardigrade. But before you get too excited, there's one little twist …

Researchers have harnessed the cancer-destroying abilities of the body’s natural killer cells. Nanodrones selectively target a tumor, enabling the killer cells suppress cancer growth, opening the door to novel, cancer-specific immunotherapies.

Researchers tricked glioblastoma cancer cells in mice into taking up iron-filled carbon nanotubes. They then shredded those cells by spinning the tubes using magnetic force. The technique has the researchers hopeful for a similar result in humans.

Researchers have created a working light mill that's just 100 nanometers in size.
