A Northwestern University environmental engineer has received a U.S. patent for a treatment device that renders perchlorate — a thyroid-damaging ingredient of rocket fuel and a drinking water problem — harmless. The applications extend beyond the safety of drinking water and this one pollutant.
Bruce E. Rittmann, John Evans Professor of Environmental Engineering at the Robert R. McCormick School of Engineering and Applied Science, received U.S. Patent No. 6,387,262 for a hollow-fiber membrane biofilm reactor, that, through a natural biochemical process of electron transfer, turns perchlorate into innocuous chloride.
The cost-effective and environmentally friendly system also works on nitrate, a contaminant from agricultural fertilizers that can cause methemoglobinemia, or blue-baby syndrome, in infants, and is expected to be successful with other oxidized pollutants, such as bromate, selenate, heavy metals, radionuclides, and a range of chlorinated solvents, including trichloroethylene, a problem in the semiconductor industry.

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...
