Smoking is a turn-on for some genes: study
September 30, 2007 05:43 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.

RENO (Reuters) - Search teams on foot, horseback and all-terrain vehicles resumed their quest on Sunday in western Nevada for millionaire adventurer Steve Fossett, missing since taking off alone in a small plane on September 3.
The ground search, now in its second day, focused on a patch of rugged terrain identified by U.S. Air Force radar analysis as an area where Fossett's aircraft was likely to have gone down, said Gary Derks, a state Department of Public Safety official overseeing the operation.
Speaking to Reuters by telephone from the command center in Nevada's capital, Carson City, Derks said the teams were expected to finish covering the search area of roughly 50 to 60 square miles by nightfall.
Consumers worried about plastic bags' impact on the environment

They're initially used for mere minutes, they cost only pennies to make and are rarely given much afterthought.
But more and more consumers and communities are thinking twice about the everlasting life of plastic bags.
They offer a convenient carry-all for everything from cereal to CDs to cosmetics.
But then what?
FDA staff urge warnings on kids' cold medicines
September 29, 2007 03:50 PM -
WASHINGTON (Reuters) - Over-the-counter cough and cold medicines that contain decongestants and antihistamines should come with new instructions saying they are not recommended for very young children, U.S. Food and Drug Administration reviewers have recommended.
The FDA has not made a final decision on whether to change the warnings or instructions for use on the widely used drugs, officials said in documents released late on Thursday. The agency will seek input from a panel of outside advisers next month.
Officials said in March they were reviewing use of over-the-counter cough and cold medicines in children. A group of doctors and public health officials had filed a petition voicing concerns that the drugs were risky and not effective for children.
Little-known Indian tribe spotted in Peru's Amazon

LIMA (Reuters) - Ecologists have photographed a little-known nomadic tribe deep in Peru's Amazon, a sighting that could intensify debate about the presence of isolated Indians as oil firms line up to explore the jungle.
Carrying arrows and living in palm-leaf huts on the banks of the Las Piedras river, the tribe was glimpsed last week by researchers flying over the Alto Purus national park near the Brazilian border to look for illegal loggers.
"We saw them by chance. There were three huts and about 21 Indians -- children, women and young people," said Ricardo Hon, a forest scientist at the National Institute of Natural Resources.
UK To Airlines: Green Up Or Else
September 28, 2007 07:29 PM - Paul Schaefer, ENN
London, -- The United Kingdom told airlines to green up, or else, and soon. The government acted decisively today to safeguard the proposed European aviation emissions trading scheme and urged the international aviation community to take greater action to address aviation emissions. Secretary of State for Transport Ruth Kelly, said: "We want to work with our international partners to achieve a global solution to this global problem. If international negotiations deliver an effective solution then we will have achieved our goal through co-operation. But I am also clear that the UK, and the environment, cannot wait for ever. That is why we are reserving the right - if an international solution is not found - to act in the wider global interest by extending the EU emissions trading scheme to all flights arriving and departing from the European Union.

Drinking may dampen hearing in the short term
September 28, 2007 05:50 PM -
NEW YORK (Reuters Health) - If you have a hard time hearing conversation at a bar, it may not be because of the noise, a study suggests.
Alcohol, UK researchers found, seems to temporarily drain a person's hearing -- particularly when it comes to discerning the sounds of conversation.
In a study of 30 healthy volunteers, they found that as participants drank, their hearing became less acute. Lower-frequency hearing, which is necessary for discerning speech, suffered the most, the researchers report in the online journal BMC Ear, Nose and Throat Disorders.
Agrilandia Farm: Italy’s Slow Food Culture Comes to Beijing
September 28, 2007 10:10 AM - Lila Buckley, Worldwatch Institute
Nestled in the dusty northern suburbs of Beijing, the village of Baige Zhuang seems like an unlikely birthplace for fine Italian wines and cheeses. But since 1999, Agrilandia Italian Farm has been producing handcrafted organic red wines, fruit wines, cheeses, and conserves in Beijing’s remote suburbs, in an attempt to bring the philosophy of Italian ecological agriculture to the Chinese capital.
