“We’ve seen the price of food become more expensive than ever three times in five years. Normally we’d see three price spikes in a century,” said Kaufman. “And part of the reason is this new kind of commodity speculation in food markets.” In an article published Oct. 24 in Nature[subscription required], Kaufman describes what he calls “Wall Street’s thirst for water” — the push to turn water into a commodity like food, with the same instruments that produced the mortgage-backed security collapse and 2008 financial crisis.Public or Private: The Fight Over the Future of Water [more inside]
The Experimental Lakes Area (ELA) is a unique research facility in northern Ontario comprised of 58 lakes set aside by the Government of Canada in which entire lakes are used for experimental manipulation. ELA has effectively solved the problems of nutrient loading and acid rain in freshwater ecosystems. As well, it has produced top research on the effects of estrogen, climate change and methylmercury in freshwater. Current research includes the impacts of nanosilver, climate change, transgenic fish and flame retardants on aquatic ecosystems aquatic ecosystems. On March 31, 2013, The Harper Government will close the Experimental Lakes Area. [more inside]

Got Water? Fresh water is a necessity for human survival, but many areas of the world are starting to feel the crunch. One solution to this problem that has been applied in a few areas is collecting fresh water from fog (here's how!). This technology has been a boon to places like Chungungo, Chile. Now a small beetle from the Namib Desert may hold the key to making fog collection even more successful. Water attracting and repelling bumps and valleys on the beetle's wings collect and transport water from fog. Currently, QinetiQ is developing synthetic materials with these same properties, which may make the similar technique of dew collection even more feasible.
