Report: Water shortage risk ranked by country
Problems such as the growing shortage of fresh water (drinkable or industrial grade) are not just public or governmental concerns. Agriculture, manufacturing, and general business also require copious, inexpensive and reliable sources of water – so it’s not surprising that research organizations that cater to business needs also take the problems seriously. Such is the [...]

New study: Chemical mixture toxicity
The situation is simple to describe: Almost all toxicity testing of pollutants is done on a chemical-by-chemical basis. Almost none of the testing involves multiple pollutants in combination (a chemical cocktail, a suite of pollutants, a toxic mix). Chemicals thrown together have a tendency to interact, producing new chemicals. This is particularly true when the [...]

NEMo – squeezing the dirt out of diesel
Some of the technology with the biggest impact isn’t new or revolutionary; it’s making old technology work better. Cases in point, researchers at the Technische Universität München (Technical University of Munich, TUM) continually modify and test diesel engines to meet and exceed current (and future) emission standards. I suppose this is the sort of engineering [...]
