Study Claims Smoking not linked to more advanced breast cancer
October 28, 2007 11:54 PM - Reuters
WASHINGTON (Reuters) - In a study that is sure to be questioned and criticized, one research group claims that women who develop breast cancer are no more likely to have aggressive or advanced tumors if they are cigarette smokers than if they do not smoke. The study's author, Dr MatthewAbramowitz said the study did not evaluate whether smokers were more likely than nonsmokers to have complications in treatment for breast cancer or die from the disease. However, the National Cancer Institute said cigarette smoking causes 87 percent of lung cancer deaths and is responsible for most cancers of the larynx, mouth, esophagus and bladder. The group emphasizes that tobacco use, particularly cigarette smoking, is the most preventable cause of death in the United States.
Discovery may help treat drug addicts

SANTIAGO (Reuters) - Chilean scientists have made a discovery in the brains of rats that they say may help treat drug addiction and ease the side effects of some medications.
Researchers at the Pontifical Catholic University in Santiago say they identified a region of the brain, the insular cortex, that plays an important role in drug craving.
Tests on amphetamine-addicted laboratory rats showed that when the insular cortex was deactivated by injecting a drug that halted brain cell activity, the rats showed no signs of addiction.
Edwards unveils plan to control drug advertising
October 28, 2007 11:27 PM -
WASHINGTON (Reuters) - Democratic presidential candidate John Edwards on Sunday unveiled a plan to put controls on drug advertising, which he said were misleading patients and driving up health care costs.
The former North Carolina senator, who has attacked lobbyists and championed the concerns of the poor in his campaign, proposes delays on consumer advertising of new drugs and tougher Food and Drug Administration oversight over drug marketing.
"The excessive costs of prescription drugs are straining family budgets and contributing to runaway health care costs," Edwards said at the start of a seven-day campaign tour of the early-voting states of New Hampshire and Iowa.

ROCKVILLE, Maryland (Reuters) - In a nondescript office park tucked between a hospital and a strip mall thrive hundreds of thousands of the most infectious malaria-carrying mosquitoes ever born.
They will be dissected for the motherlode that they carry -- baby malaria parasites, fodder for a new malaria vaccine.
The insects' suburban Maryland home is owned by Sanaria Inc., which cut the ribbon on Friday on its new facility. Founder and chief executive officer Dr. Stephen Hoffman is taking a gamble that he can do what has been impossible -- make a vaccine against malaria.

Children kept indoors as Beijing fog turns to smog
October 26, 2007 12:17 PM -
BEIJING (Reuters) - Beijing's weather office warned children and the elderly to stay indoors on Friday as heavy fog blanketed the host city of the 2008 Olympics, exacerbating its chronic air pollution, Chinese state media reported.
Fog caused severe delays at Beijing airport and reduced visibility in the centre of the city to less than 200 meters.
"The fog will not only affect the traffic but also harm humans' respiratory system. I suggest old people and children avoid going outdoors or wear a mask," Sun Jisong, the city's chief weatherman, told the official Xinhua news agency.

LOS ANGELES (Reuters) - Four burned bodies found in the path of California's fierce wildfires raised the death toll to at least 12 people, even as firefighters won the upper hand and officials turned on Friday toward assessing the damage.
Though more than 20 fires raged across Southern California into a sixth day, some 8,000 firefighters had brought most of them under control and no more homes were in imminent danger.
Some lost everything to the flames but most of the 500,000 people forced to flee in California's largest evacuation were expected to be back in their homes by the weekend.

PARIS (Reuters) - President Nicolas Sarkozy promised a green revolution on Thursday, unveiling a mix of tax measures and investment pledges that he said would put France in the vanguard of the war against global warming.
"France isn't late but France wants now to be in the lead," he said in a speech wrapping up a special environmental policy conference seeking ways to cut greenhouse gas emissions and help change attitudes to the environment.
The congress was one of the highest profile green initiatives ever launched in France and fulfilled an election campaign promise by Sarkozy, who has said his government will emphasize sustainable development.
U.N. says world in dire straits
October 25, 2007 07:42 PM - Jeremy Lovell
LONDON (Reuters) - Two decades after a landmark report sounded alarm bells about the state of the planet and called for urgent action to change direction, the world is still in dire straits, a U.N. agency said on Thursday.
While the U.N. Environment Program's fourth Global Environment Outlook (GEO-4) says action has been successfully taken in some regions and on some problems, the overall picture is one of sloth and neglect.
"The global trends on climate, on ozone, on indeed ecosystem degradation, fisheries, in the oceans, water supplies ... are still pointing downwards," UNEP head Achim Steiner said in a short film accompanying the report's release.
Study: Mercury Pollution Threatens Idaho Children
October 25, 2007 03:37 PM -
Reno, Nevada - New emissions data, obtained from the Nevada Department of Environmental Protection (NDEP), show that northern Nevada gold mines are still under-reporting substantial amounts of mercury air pollution. It also reveals that a number of mines that were previously considered small sources of mercury air pollution are actually very large sources, yet these mines have few pollution controls in place. Until 2006, mines were not required to actually measure mercury releases, only estimate mercury emissions.
Mercury exposure is a serious pubic health concern, particularly for children. Exposure to mercury can cause significant neurological and developmental problems such as attention and language deficits, impaired memory and impaired vision and motor function.
