WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

...rol strategies including establishment of a proper drainage system and engineering methods are key components of WHO's long-term strategy to rehabilitate the damaged or destroyed public health infrastructure. To implement this health system rehabilitation strategy, WHO urgently requires US$67 million for acti...

Road salt affects mitigation wetlands

...the Behrend campus, PennDOT installed an elaborate drainage system beneath the road to collect all the runoff. The water goes to only one of the six constructed wetlands and eventually runs downhill through woodlands. Silver is monitoring two PennDOT-installed data loggers to measure the amounts of salt that...

Proteomics brings researchers closer to understanding microbes that produce acid mine drainage

...ria in a slime, or biofilm, responsible for acidic drainage from the mine. Now, they have gone further and, with the help of colleagues at the DOE's Oak Ridge National Laboratory, identified the proteins that go with these five organisms, their so-called proteomes. The technique they used is the first succes...

Katrina floodwaters not as toxic to humans as previously thought, study says

...al samples were also obtained from the 17th Street drainage canal, after pumping of the floodwater began, to evaluate the flood's impact on Lake Pontchartrain, the receiving body for the pumped floodwaters.

The vicious cycle of rainforest destruction

...avanna. Other issues such as soils, fertility and drainage must play a part, the researchers believe. They will make measurements in Africa, Australia and South America, focusing on 'zones of tension' where rainforest and savanna currently grow side by side. Using these measurements, detailed computer model...

Migration alert -- How tumor cells home in on the lymphatic system
