A University of Exeter academic has spoken about the many chemical elements we rely on that are at risk.
Professor Frances Wall, Head of the University’s Camborne School of Mines, joined a panel of experts at the British Science Festival to reveal the new chemical ‘risk list’. (more…)
Is it possible to make valid climate predictions that go beyond weeks, months, even a year? UCLA atmospheric scientists report they have now made long-term climate forecasts that are among the best ever — predicting climate up to 16 months in advance, nearly twice the length of time previously achieved by climate scientists.

*Three-year series of scientific missions from Arctic to Antarctic produces new views of atmospheric chemistry*
A three-year series of research flights from the Arctic to the Antarctic has successfully produced an unprecedented portrait of greenhouse gases and particles in the atmosphere.
The far-reaching field project, known as HIPPO, ends this week, and has enabled researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth’s climate. (more…)
EAST LANSING, Mich. — Researchers at Michigan State University have unraveled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals.
Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. The implications could eventually benefit sites forever changed by nuclear contamination, said Gemma Reguera, MSU microbiologist. (more…)
In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well spewed oil at a rate of about 57,000 barrels a day, totaling nearly 5 million barrels of oil released from the well between April 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas. (more…)
*The recent returns of Atlantic salmon in the Thames are more likely to be a result of fish straying from nearby rivers rather than a consequence of expensive restocking efforts, according to new research by the University of Exeter.*
A team of University of Exeter bio-scientists, in collaboration with the Environment Agency, Westcountry Rivers Trust and Oviedo University, Spain, have been collecting genetic data from returning fish, which suggests that habitat restoration was more effective than re-introductions. The findings will be published in the journal ‘Biological Conservation’.
Lessons from the study could be applied to other rivers across the UK according to the co-author of the paper Dr Jamie Stevens, Associate Professor of Molecular Systematics at the University of Exeter. Dr Stevens says: “Traditionally, people – such as river owners and anglers – have wanted big fish swimming up their rivers. The easiest way to ensure this quickly has been to restock those rivers with exogenous fish (from outside the river system).” (more…)
*Water significant limiting factor in growing crops like switchgrass*
Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.
They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.
“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)
Researchers pursue new information from East Coast hurricane
While Hurricane Irene had officials along the East Coast preparing for mass evacuations, scientists at the Stroud Water Research Center and the University of Delaware were grabbing their best data collection tools and heading straight for the storm’s path. (more…)
