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."

A study carried out by an international team of researchers and published in the journal Physical Review X shows that ion-trap technologies available today are suitable for building large-scale quantum computers. The scientists introduce trapped-ion quantum error correction protocols that detect and correct processing errors.
In order to reach their full potential, today’s quantum computer prototypes have to meet specific criteria: First, they have to be made bigger, which means...
