A new study from North Carolina State University finds that fish located near coal-fired power plants have lower levels of mercury than fish that live much further away. The surprising finding appears to be linked to high levels of another chemical, selenium, found near such facilities, which unfortunately poses problems of its own. "We found that fish in lakes located at least 30 kilometers (km) from a coal-fired power plant had mercury levels more than three times higher than fish of the...

Human impact is causing lower oxygen and higher carbon dioxide levels in coastal water bodies. Increased levels of carbon dioxide cause the water to become more acidic, having dramatic effects on the lifestyles of the wildlife that call these regions home. The problems are expected to worsen if steps aren't taken to reduce greenhouse emissions and minimize nutrient-rich run-off from developed areas along our coastlines. The ocean is filled with a soup of bacteria and viruses. The animals...

Mice at altitude save oxygen during exercise by using more carbohydrates rather than fat, Canadian and Peruvian scientists reveal This fuel-preference represents an adaptation in high altitude mice to use oxygen more efficiently than their low-altitude counterparts. "Andean mouse species have independently evolved a strategy to maximize energy yield when little oxygen is available" explain lead researchers Marie-Pierre Schippers and Grant McClelland from McMaster University. It is very...

The molecular secrets of a bacterium which produces its own oxygen to use the green house gas methane was unraveled A Dutch research team from the University of Nijmegen discovered bacteria that oxidize the methane without oxygen. Instead, these bacteria used nitrite, commonly available in freshwater sediments in agricultural areas. Methane is a very stable molecule and its degradation was generally believed to be impossible without oxygen (or sulfate). Now an international team from the The...

Now, research published in BioMed Central's open access journal Nutrition and Metabolism, has shown that, for men, high plasma selenium concentrations are associated with a lower occurrence of dysglycemia. Tasnime Akbaraly, from the University of Montpellier, worked with a team of researchers to follow 1162 healthy French men and women...
