Scientists in Pennsylvania are reporting development of a fuel cell that uses pollution from coal and metal mines to generate electricity, solving a serious environmental problem while providing a new source of energy. They describe successful tests of a laboratory-scale version of the device in a new study.

In the new study, Bruce E. Logan and colleagues point out that so-called acid-mine drainage (AMD) is a serious environmental problem that threatens the health of plants and animals as well as the safety of drinking-water supplies, due mainly to the high acidity of contaminated waters and its high content of metals, particularly iron. AMD poses difficult and costly environmental clean-up problems.

They describe development of a new type of fuel cell that is based on microbial fuel cells, which are capable of generating electricity from wastewater. Using a solution similar to AMD, they showed that the device efficiently removed dissolved iron from the solution while also generating electricity at power levels similar to conventional microbial fuel cells. Improvements in the fuel cell will lead to more efficient power generation in the future, the researchers say. The iron recovered by the device can be used as a pigment for paints or other products, they note.

The article "Electricity Generation from Synthetic Acid-Mine Drainage (AMD) Water using Fuel Cell Technologies" is scheduled for the Dec. 1 issue of ACS' Environmental Science & Technology.

60 Years of Research Links Gluten Grains to Schizophrenia
2015-03-31 1:05
Does the consumption of gluten-containing grains contribute to psychiatric disorders such as schizophrenia? Believe it or not, this question has been asked for well over 60 years by researchers who stumbled upon evidence that the removal of gluten from the diet results in improved symptoms, or conversely, that gluten grain consumption leads to higher prevalence of both neurological and psychiatric problems. Reports ...
A Sour Deception: Citric Acid Comes From GMO Black Mold, Not Fruit

Just what is your food made of, anyway? Try industrial synthesis, genetically modified mold secretions, hydrochloric acid, mercury-contaminated caustic soda, ferrocyanide… and, of course, lots of GMO corn. If common ingredients like “citric acid” and “ascorbic acid (Vitamin C)” sound normal and familiar enough that you practically conjure up an image of the flourishing orchard they were grown in – then ...
Thousands of migrants dumped on Britain as French wriggle out of border promise
2015-03-30 19:56
Thousands of migrants could be dumped on Britain’s doorstep if France tears up a historic border agreement, it was claimed last night. Officials have vowed to do “everything in their power” to wriggle out of a treaty moving the UK border to Calais. The besieged town’s mayor Natacha Bouchart is prepared to spark a major diplomatic row by opening the frontier ...

King Richard III was today laid to rest at Leicester Cathedral - more than 500 years after his death in battle. The monarch, who reigned from 1483 to 1485, was the last of the Plantagenet dynasty. Actor Benedict Cumberbatch read a poem by Carol Ann Duffy during the service. Also in attendance was Robert Lindsay, who played Richard III in a version ...
Sweden - A new paradise for Romani beggars

Thanks to the European Union and freedom of movement that follows with membership Sweden has been flooded with gypsies from Eastern Europe. Most member states have cracked down hard on the phenomenon of organized begging with legislation and forceful evictions so the Romani (colloquially known as Gypsies) who are engaged in this venture have moved their business to the country where ...
