A new article published in Current Protocols in Microbiology provides detailed instructions for constructing and using low-cost biological sand (biosand) filters capable of dramatically improving the quality of drinking water. The article has been made available for free and can be viewed here.
Biological sand filters, which have gained acceptance by the World Health Organization as a viable household water treatment technology, work by having water percolate slowly through a layer of sand, where microorganisms form a bacteriological purification zone. This process filters harmful pathogens from contaminated water. To use the filter, a person simply pours contaminated water into the household biosand filter and immediately collects treated water.
The filters will do more than provide safe, clean drinking water. According to Michael Lea, author of the article, "the filters will provide a cost-effective practical approach to combat poverty and inequality."

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
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...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
