U.S. researchers travel to Canada next spring to study simulated global warming involving about 2,000 sugar maple tree seedlings. Northern Illinois University Professors Lesley Rigg and David Goldblum have been awarded a $260,000 National Science Foundation grant to simulate global warming on sugar maple seedlings now growing in Canada's Lake Superior Provincial Park. The researchers will build rain-exclusion, temperature-controlled structures over the seedlings to simulate temperature...

By Richard Nunnally, Richmond Times-Dispatch, Va. Sep. 15--Q:I grow tomatoes every year and find those big green worms on them. Some have white lumps on their backs. I've heard they are some kind of eggs. Is that true? If so, are they harmful? Answer: The worms you're seeing are tomato hornworms. They are common and enjoy eating the leaves of tomato plants. The white lumps are the egg cases for a parasitic wasp. This wasp stings the worm and deposits its eggs on the worm's back. As the...

SPOKANE, Wash. (AP) - A fungus scientists have dubbed "Black Fingers of Death" may turn out to be the first long-range weapon in efforts to halt the advance of cheatgrass, a destructive invasive weed, scientists say. Gonzaga University biology professors Julie Beckstead and David L. Boose were recently awarded $247,000 in federal grants for a three-year study on pyrenophora semeniperda, a tiny, naturally occurring soil fungus that attacks the seeds of cheatgrass. Working with colleagues at...

DES MOINES, Iowa -- A new species of North American bamboo was recently discovered by Iowa State University and University of North Carolina botanists, making it the third known native species of the hardy grass in the United States. The "hill cane" was discovered in the Appalachian Mountains. It's different from the other two native species of bamboo, which were discovered more than 200 years ago, because it drops its leaves in the fall. "We tend to think that we ... know our own...

NEW YORK -- America is drunk on ethanol. Farmers in the Midwest are sending billions of bushels of corn to refineries that turn it into billions of gallons of fuel. Automakers in Detroit have already built millions of cars, trucks and SUVs that can run on it, and are committed to making millions more. In Washington, politicians have approved generous subsidies for companies that make ethanol. And just this week, President Bush arranged with Brazil's President Luiz Inacio Lula da Silva for...

By SHANNON MONTGOMERY EDMONTON (CP) - Alberta wants forestry companies to step up the cutting of pine trees to help deal with a massive outbreak of destructive mountain pine beetles. Millions of the tiny insects have made their first major advance into Alberta's northern forest, settling in for the winter in up to 1.5 million trees - up from only 19,000 trees last year. The infestation has the government and industry scrambling to try and contain a scourge that has already ruined huge...

WASHINGTON -- Ethanol is far from a cure-all for the nation's energy problems. It's not as environmentally friendly as some supporters claim and would supply only 12 percent of U.S. motoring fuel - even if every acre of corn were used. A number of researchers, the latest in a report Monday, are warning about exaggerated expectations that ethanol could dramatically change America's dependence on foreign oil by shifting motorists away from gasoline. As far as alternative fuels are concerned,...

DES MOINES, Iowa (AP) - Iowa is at risk of losing its state tree - the oak - and residents are being urged to plant more of them to keep them from disappearing. The number of oak trees in the state has been dwindling, in part because of diseases, such as oak wilt and oak tatters. Another problem is nature itself, officials said. Without fires that kept different species in check before widespread farming and development, Iowa has become full of shady maples and basswoods while the number of...

GRANGEVILLE, Idaho -- Northwest loggers are worried British Columbia may be forced to harvest as much as 21 million acres of forests to stop the mountain pine beetle, flooding the market and driving down timber prices. The infected forests in British Columbia make up an area roughly 40 percent the size of Idaho. To combat the beetles, the province is increasing allowable timber cuts 78 percent; big trouble for mills throughout the Northwest. "They're going to bury us in the sand," said Dick...

In this study the possibilities of the North American oak (Quercus rubra L.) as an afforestation alternative in the Basque Country Autonomous Community were investigated. The aim was to expand the range of possibilities in forestry production, avoiding monospecific plantations but, at the same time, meeting the needs of the current economy on the basis of sustainable development. The study centred on 6 plantations of various ages in Bizkaia, firstly studying the wealth of epigeous fungi...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
