New Laser technique

''Canadian researchers have created a new protein patterning technique that's enabled them to reproduce complex cellular environments and a miniature version of a masterpiece painting.
...
To illustrate the precision of their protein patterning technique, the research team reproduced a masterwork of Dutch painter Johannes Vermeer, specifically Girl with a Pearl Earring, in the miniature dimension of 200 microns wide or about the thickness of two hairs. The researchers also used their novel technology to replicate the brain's complex cellular environment. It's a major discovery, since the new laser technology can encourage and guide the growth of finicky nerve cells. '' [source]
