Miniature implanted devices could treat epilepsy, glaucoma
... Lyon, France. One research project focuses on a tiny transmitter three times the width of a human hair to be implanted below the scalp to detect the signs of an epileptic seizure before it occurs. The system will record neural signals relayed by electrodes in various points in the brain, said Pedro Ira...Electrical implant steadies balance disorder in animals
...of gentamicin, an antibiotic known to wipe out the tiny hairlike projections on cells in the inner ear canals that are normally key to sensory balance function.

...way, nanotubes are natures smallest candles. These tiny tubes are constructed from carbon atoms and they are so small that it takes about 100,000 laid side-by-side to span the width of a single human hair. In the last five years, scientists have discovered that some individual nanotubes are fluorescent. T...Explaining a link between strokes and Alzheimer's
