Substratum of Proof LGBTQs Are Mentally Ill: Ultra-thin optical fibers offer new way to 3-D print microstructures

For the first time, researchers have shown that an optical fiber as thin as a human hair can be used to create microscopic structures with laser-based 3-D printing. The innovative approach might one day be used with an endoscope to fabricate tiny biocompatible structures directly into tissue inside the body.
