November 6, 2007 01:58 PM - By Will Dunham
ORLANDO, Florida (Reuters) - Inhaling diesel exhaust fumes causes changes in the body that may make people more prone to heart attack or stroke, researchers said on Tuesday.
European scientists found that blood clots are more likely to form in otherwise healthy people exposed to relatively high amounts of diesel engine exhaust for a short time. This could cause a blocked vessel, heart attack or stroke.

Seafood Companies Call on Canada to End Seal Hunt
November 6, 2007 10:36 AM - Paul Schaefer, ENN
WASHINGTON – A list of well-respected seafood distributors are boycotting select seafood imports to protect Canadadian seal populations and end Canada's seal hunting practices. These distributors supply seafood to major U.S. chains, including BJ’s Wholesale Club, Shaw’s Supermarkets, Sam’s Club and Target.
The boycott has won the full support of the influential Humane Society of the United States who applauded the participation of some of Canada's most respected seafood distributors.
“ The cruelty involved in Canada ’s commercial seal hunt is unacceptable,” said Jim Chambers of Prime Seafood, one of the top seafood suppliers to restaurants in the Washington , D.C. metro area. “I’m a bit surprised that Canada ’s sustainable seafood advocates haven’t come out against the commercial seal hunt yet. I hope they do. They have the power to help bring the hunt to an end.”
Australian researchers find hunger switch
November 6, 2007 08:23 AM - Reuters
Australian scientists have found how to switch hunger on and off using a molecule that targets the brain -- a discovery which could stop weight loss in terminally ill patients or produce weight loss in the morbidly obese.
The molecule, known as MIC-1, is produced by common cancers and targets receptors in the brain that switch off appetite. But Australian researchers found that by using antibodies against MIC-1 they were able to switch appetite back on.

ORLANDO, Florida (Reuters) - An eight-week regimen of yoga proved safe for patients with chronic heart failure and helped reduce signs of inflammation often linked with death, according to a study released on Monday.
More than 5 million Americans have chronic heart failure, a long-term condition in which the heart no longer pumps blood efficiently to the body's other organs. Health problems and deaths from the disease remain high despite widespread use of effective drug and device therapies to treat the condition.

CHICAGO (Reuters) - A study of more than 5,000 youngsters in Switzerland has found those who smoked marijuana do as well or better in some areas as those who don't, researchers said on Monday.
But the same was not true for those who used both tobacco and marijuana, who tended to be heavier users of the drug, said the report from Dr. J.C. Suris and colleagues at the University of Lausanne.

SAO PAULO (Reuters) - Florida Gov. Charlie Crist said on Monday he will encourage U.S. Congress members to lobby for more ethanol use and a reduction in the 54-cent-a-gallon tariff on Brazilian imports of the biofuel.
The use of more cane-based ethanol is seen as a way to curb greenhouse gas emissions in the U.S. state, which is aiming to reduce them to 1990 levels by 2015.
Experts Say Climate Change Threatens National Security
November 5, 2007 05:40 PM - By Deborah Zabarenko, Environment Correspondent
WASHINGTON (Reuters) - Climate change could end globalization by 2040 as nations look inward to conserve scarce resources and conflicts flare when refugees flee rising seas and drought, national security experts warned on Monday.
Scarcity could dictate the terms of international relations, according to Leon Fuerth of George Washington University, one of the report's authors.
Global cooperation based on a resource-rich world could give way to a regime where vital commodities are scarce, Fuerth said at a forum to release "The Age of Consequences."

The American Society of Landscape Architects (ASLA) has been working with the Ladybird Johnson Wildflower Center at the University of Texas–Austin since 2005 to research environmentally friendly landscapes for building sites, parks, and public areas.
In 2006, the U.S. Botanic Garden joined the effort, and now the group is going public with its Sustainable Sites Initiative (SSI), a project to develop guidelines by 2009 and a rating system for landscapes by 2012.
