By studying wild rice in lakes and streams, a team of researchers led by the University of Minnesota has discovered that sulfate in waterways is converted into toxic levels of sulfide and increases other harmful elements. This includes methylmercury, the only form of mercury that contaminates fish.

We often “flush it and forget it” when it comes to waste from toilets and sinks. However, it’s important to be able to track this wastewater to ensure it doesn’t end up in unwanted places. A group of Canadian scientists has found an unlikely solution.

A strip of chromatography paper similar to that used in rapid pregnancy tests is the basis of a bio-sensor for detecting malaria that has been developed by Brazilian researchers.

To shine light on and conserve rare shark, ray, and chimaera species (chondrichthyans), SFU researchers have developed a fully-resolved family tree and ranked every species according to the unique evolutionary history they account for.

A new study shows that a large and potentially unstable Antarctic glacier may be melting farther inland than previously thought and that this melting could affect the stability of another large glacier nearby – an important finding for understanding and projecting ice sheet contributions to sea-level rise.

New graphene printing technology can produce electronic circuits that are low-cost, flexible, highly conductive and water repellent.

A team led by the Department of Energy’s Oak Ridge National Laboratory has uncovered how certain soil microbes cope in a phosphorus-poor environment to survive in a tropical ecosystem. Their novel approach could be applied in other ecosystems to study various nutrient limitations and inform agriculture and terrestrial biosphere modeling.

Hydropower dams may conjure images of the massive Grand Coulee Dam in Washington state or the Three Gorges Dam in Hubei, China — the world’s largest electricity-generating facility. But not all dams are the stuff of documentaries. Tens of thousands of smaller hydroelectric dams exist around the world, and all indications suggest that the number could substantially increase in the future.

New research from a Florida State University scientist has revealed a surprising relationship between surging atmospheric carbon dioxide and flower blooms in a remote tropical forest.

An international team of researchers studying globally declining shark populations report today that they used carbon isotopes as biochemical markers in shark muscle tissue to identify where in the oceans the mobile predators have been feeding, in the hope that such analyses provide a useful tool for conservation. Details appear in the current issue of Nature Ecology & Evolution.
