Microbes Generate Electricity While Cleaning Up Nuclear Waste

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…)

WHOI-Led Study Sharpens Picture of How Much Oil and Gas Flowed in Deepwater Horizon Spill

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…)

Re-emergence of Salmon in The Thames ‘Not From Restocking’ Say Exeter Academics

*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…)

Testing the Water for Bioenergy Crops

*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…)

Hurricane Irene: Scientists Collect Water Quality and Climate Change Data from Huge Storm

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…)

Irene Highlights Critical Roles of Government, Public

EAST LANSING, Mich. — As Tropical Storm Irene shows, dealing with natural disasters is a two-way street: Both the government and the public play a critical role in curtailing the effects, according to a Michigan State University political scientist.

In her new book “Dealing with Disaster,” Saundra Schneider contends it’s not the size of the disaster or the amount of money spent on relief that determine success or failure of an emergency response. Instead, it’s the “inevitable gap” between government procedures and the collective behavior of victims. (more…)

NASA Satellite Shows a Mean Irene’s Fury

After pounding North Carolina and Virginia on Aug. 27, Hurricane Irene made a second landfall near Little Egg Inlet, N.J., early Sunday morning, Aug. 28, still as a category one hurricane with maximum sustained winds of 75 mph (120 kilometers per hour). It then weakened slightly before making a third landfall over Coney Island, N.Y. as a 65-mph (100-kilometer-per-hour) tropical storm. Irene’s heavy rains, winds and storm surge are causing widespread problems throughout the U.S. mid-Atlantic and Northeast. (more…)

Thawing Permafrost Could Release Vast Amounts of Carbon and Accelerate Climate Change by the end of this Century

*New computer modeling study, led by a Berkeley Lab scientist, could help revise understanding of permafrost’s role in global warming*

Billions of tons of carbon trapped in high-latitude permafrost may be released into the atmosphere by the end of this century as the Earth’s climate changes, further accelerating global warming, a new computer modeling study indicates.

The study also found that soil in high-latitude regions could shift from being a sink to a source of carbon dioxide by the end of the 21st century as the soil warms in response to climate change. (more…)
