Measurements as well as model calculations equally show that the oxygen inventory of the oceans is decreasing. However, the models underestimate this decrease significantly making projections into the future problematic. In a study published today in the international journal Nature Geoscience, four GEOMAR researchers reveal the gaps in the models and identify further, previously underestimated drivers for the deoxygenation.
Led by the University of Manchester, an international team of scientists has developed a metal-organic framework material (MOF) that exhibits a selective, fully reversible and repeatable capability to remove nitrogen dioxide gas from the atmosphere in ambient conditions. This discovery, confirmed by researchers using neutron scattering at the Department of Energy’s Oak Ridge National Laboratory, could lead to air filtration technologies that cost-effectively capture and convert large quantities of targeted gases, including carbon dioxide and other greenhouse gases, to facilitate their long-term sequestration to help mitigate air pollution and global warming.
Scientists are gaining a better understanding of Pierce’s disease and how it affects grapevines. The disease, which annually costs California more than $100 million, comes from a bacterium called Xylella fastidiosa.
University of Otago researchers are helping lead international studies which have discovered that exposure to cattle and rice farming are risk factors for the devastating disease leptospirosis in northern Tanzania.
Almost a third of the natural gas fuelling UK homes and businesses could be replaced by hydrogen, a carbon free fuel, without requiring any changes to the nation’s boilers and ovens, a pioneering study by Swansea University researchers has shown.
Graduate student David Capelle has returned form a fruitful time in the field working with his advisor Tim Papakyriakou. He files this report on his research investigating carbon cycles in Hudson Bay.
