Helium Ions Replace Electrons in Novel Microscope Technology

Researchers affiliated with the Institute for NanoBioTechnology hope to gain some insight into the potentially hazardous effects of inhaled nanometals by studying their ability to access lung tissues, their potential to trigger pro-inflammatory reactions by cells that line the lung airways, and even the extent to which workers are exposed in a nanomaterials manufacturing setting.

World's smallest nano car..as thin as hair made by scientists..marvellous feat by scientists

Using the parts inside a single molecule, scientists have constructed the world's smallest car. It has a chassis, axles and a pivoting suspension. The wheels are buckyballs, spheres of pure carbon containing 60 atoms apiece.

It'd be a real squeeze to take it for a spin, however.

The whole car is no more than 4 nanometers across. That's slightly wider than a strand of DNA. A human hair is about 80,000 nanometers thick.
