Canada not listening to leading environmentalist
October 14, 2007 10:20 PM - Jonathan Spicer
TORONTO (Reuters) - David Suzuki, Canada's best-known environmentalist, has spent a generation encouraging Canadians to look after the environment, but it seems they have not been listening.
Goateed, soft-spoken and avuncular, Suzuki has built a devout following from 28 years narrating "The Nature of Things," a popular television series on the science of the natural world.
Now aged 71, he notes Canada's environmental credentials are eroding just when he says it is more important than ever to move in the opposite direction.
Smoking Turns On Cancer Genes, Permanently: Study
October 14, 2007 09:59 PM -
WASHINGTON (Reuters) - Smoking may turn on some genes in the body in a permanent and harmful way, scientists said on Thursday in a study that may help explain why the risk of cancer remains high even after smokers quit.
They found many genetic changes that stop when a smoker quits, but found several genes that stay turned on for years, including several not previously linked with tobacco use.
"These irreversible changes may account for the persistent lung cancer risk despite smoking cessation," the researchers wrote in their report, published in BioMed Central journal BMC Genomics.
Genes found that slow both aging and cancer
October 14, 2007 09:52 PM - Maggie Fox, Health and Science Editor, Reuters
WASHINGTON (Reuters) - Researchers have identified a batch of genes that not only prevent cancer but slow the aging process in worms, and say they are now looking to see if the genes have the same properties in humans.
Many of the genes in the worms are already known to have counterparts in humans, and the team at the University of California, San Francisco, say they hope to better understand some of the processes that cause both aging and cancer.
Drugs that mimic the effects of these genes might help people both avoid cancer and also live longer, they wrote in Sunday's issue of the journal Nature Genetics.
Tea struggles for place in 21st century Asia
October 14, 2007 09:45 PM - Ralph Jennings, reuters
TAIPEI (Reuters) - From Beijing to Tokyo, Seoul, Hong Kong and Taipei, faced-paced modern life means that tea has little appeal for Asian youth who don't have the patience to wait the 10 minutes it takes to brew tea in the traditional way.
"I don't have any time or relevant tea culture," said Becca Liu, a 25-year-old college graduate in Taipei.
"I'm more curious to know how to make coffee," she added. Determined to restore tea to its exalted status in Asia, tea lovers are trying to repackage tea as a funky new-age brew to a young generation more inclined to slurp down a can of artificially-flavored tea than to sip the real thing.
Schwarzenegger signs handgun "microstamp" bill
October 14, 2007 09:39 PM -
SAN FRANCISCO (Reuters) - California Gov. Arnold Schwarzenegger has signed a bill whose backers say will better help police use shells from hand guns as evidence in criminal investigations, a spokeswoman said on Sunday.
The legislation marks a victory for gun-control activists and the second time Schwarzenegger signed one of their priority bills. In 2004 he approved a ban on private citizens owning .50 caliber rifles.
Illinois firm recalls beef patties on E.coli scare

WASHINGTON (Reuters) - J&B Meats Corp. is recalling 173,554 pounds (78.7 tonnes) of frozen ground beef products sold under "Topps" and "Sam's Choice" labels due to possible E. coli contamination, the U.S. government said this weekend.
The Coal Valley, Illinois-based company produced the patties in June and distributed them to retail stores nationwide, the U.S. Agriculture Department's Food Safety and Inspection Service, or FSIS, said in a statement.
Most Land-Efficient Diet: Some Dairy, Less Meat
October 14, 2007 10:41 AM - Susan Lang, Cornell University
Ithica, New York - A low-fat vegetarian diet is very efficient in terms of how much land is needed to support it. But adding some dairy products and a limited amount of meat may actually increase this efficiency, Cornell researchers suggest.This deduction stems from the findings of their new study, which concludes that if everyone in New York state followed a low-fat vegetarian diet, the state could directly support almost 50 percent more people, or about 32 percent of its population, agriculturally. With today's high-meat, high-dairy diet, the state is able to support directly only 22 percent of its population, say the researchers.
Pollution Killing up to 25,000 Canadians Annually :Report
October 14, 2007 09:21 AM - The University of British Columbia
Canadians are awash in toxic chemicals -- and it is costing our health care system up to $9.1 billion and 1.5 million hospital days annually, according to a new study led by University of British Columbia Trudeau Scholar David Boyd.
The research is the first to measure the magnitude of adverse health effects caused by exposure to environmental hazards such as air pollution, pesticides, dioxins, heavy metals, flame retardants and other persistent organic pollutants (POPs) for Canada.
Planet Wins Nobel Prize
October 14, 2007 09:18 AM - , Worldwatch Institute
The awarding of the Nobel Peace Prize to Al Gore and the United Nations’ Intergovernmental Panel on Climate Change (IPCC) is a triumph for the planet and its inhabitants, who will increasingly struggle to adjust as the world warms.
It is with extreme satisfaction that we receive the news that Gore and the IPCC have been awarded the Nobel Peace Prize,” said Oystein Dahle, Chairman of the Board of Worldwatch Institute and a leading Norwegian environmentalist.
China plans national park to outsize Yellowstone
October 14, 2007 09:10 AM - Reuters
China plans to create a vast national park in the remote northwestern region of Xinjiang that would be even bigger than Yellowstone National Park in the United States, the world's first.
The Kanas Geological Park will be expanded tenfold to around 10,000 sq km (3,860 sq miles) over the next few years as it incorporates surrounding grasslands and tourist resorts, the Xinhua news agency said, citing the park's administrators.
