Diarrheal disease from contaminated water is the second leading cause of death among children under the age of five, claiming more than 360,000 lives annually. Now, a new study of children in 35 countries finds that those living in a watershed with more trees had a lower risk of contracting the illness.

Excess solar flux could be harnessed and used to generate additional electricity at a tower CSP plant, by cladding part of the tower containing the receiver with photovoltaic (PV) panels, according to Sandia scientist Cliff Ho. He found that adding PV on the tower could generate over 10 MW, or 10% of the total capacity of a 100 MW CSP plant, using the same reflected sunlight off heliostats used to focus “suns” up onto the tower receiver for thermal solar generation.

Horned Larks are cute songbirds with white bellies and yellow chins—at least, now they are.

Fast-moving wildfires are devastating parts of Northern California, including Sonoma and Napa Counties, just north of the Bay Area. Victims — and their animals — displaced by evacuation orders and property loss need your help.

While the policy debate surrounding crude oil transportation costs has emphasized accidents and spills, a new study by Carnegie Mellon University and University of Pittsburgh researchers indicates the debate is overlooking a far more serious external cost—air pollution and greenhouse gas emissions. 

While burning coal today causes Earth to overheat, about 300 million years ago the formation of that same coal brought our planet close to global glaciation. For the first time, scientists show the massive effect in a study published in the renowned Proceedings of the US Academy of Sciences. When trees in vast forests died during a time called the Carboniferous and the Permian, the carbon dioxide (CO2) they took up from the atmosphere while growing got buried; the plants’ debris over time formed most of the coal that today is used as fossil fuel. Consequently, the CO2 concentration in the atmosphere sank drastically and Earth cooled down to a degree it narrowly escaped what scientists call a ‘snowball state’.

A foul smell and safety concerns can leave many residents turning their nose at the idea of a wastewater treatment plant in their neighbourhood.

But researchers from UBC’s Okanagan campus have developed a new way of making wastewater treatment dramatically safer and better smelling by using common and inexpensive chemicals.

Methane is the second most powerful greenhouse gas and concentrations are rising in the atmosphere. Because of its potency and quick decay in the atmosphere, countries have recognised that reduction of methane emissions are a means toward mitigating global warming.

Looks can be deceiving.

Look at a hundred lakes in the agricultural heartland of the United States and you will likely see green lakes surrounded by green fields. The nitrogen and phosphorus in agricultural fertilizers that help crops grow also fuel the growth of algae and cyanobacteria that in excess can turn lakes the color of pea soup.
