Art conservators have been slow to adopt lasers as restoration tools, preferring their trusty scalpels and solvents to untried technologies. But the first systematic study of the long-term effects of lasers on paintings should help ease their doubts: the results show that lasers can be superior restoration tools without sacrificing the safety of priceless works of art.
The findings are reported in the Sept. 15 print edition of Analytical Chemistry, a peer-reviewed journal of the American Chemical Society, the worlds largest scientific society.
European researchers studied the physical and chemical changes that occurred in various paint materials exposed to ultraviolet laser light, in order to address some of the unanswered questions about the effects of laser cleaning.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
