HEALTH: As AIDS Drugs Fail, Few Have Any Alternative
While modest gains have been made in lowering the cost of many life-saving HIV/AIDS drugs, these formulas no longer work for a growing number of people, who now need so-called "second-line" drugs that are still priced far out of reach.HEALTH: As AIDS Drugs Fail, Few Have Any Alternative
While modest gains have been made in lowering the cost of many life-saving HIV/AIDS drugs, these formulas no longer work for a growing number of people, who now need so-called "second-line" drugs that are still priced far out of reach.HEALTH: Campaigns Urge HIV Tests, But What Then?
The promise of new vaccines and more effective prevention programmes will fail to halt the spread of HIV/AIDS unless fear and social stigma can also be eliminated - including among those living with the disease, experts say.HEALTH: Progress on HIV Drugs Threatened by New Trade Pacts
In the midst of the world's biggest HIV/AIDS conference here, close to a hundred activists launched a noisy protest over bilateral free trade agreements, which they say elevate patent protections above the right to life-extending antiretroviral drugs.HEALTH: Cautious Optimism on Eve of Global AIDS Meet
The world's largest gathering of HIV/AIDS experts and activists will meet in Toronto starting on Sunday with renewed hopes of halting the spread of this devastating disease, which an estimated 40 million people are currently living with.ENVIRONMENT: Deep Oceans Teeming With Exotic Microbes
The world's oceans may contain 100 times more types of microbes than previously believed, scientists revealed Monday.ENVIRONMENT: Mega-Project Scrapes Bottom of Oil Barrel
Thousands of square kilometres of tar-laden soil and sand underlying Canada's boreal forests are being gobbled up to feed an insatiable appetite for oil in the U.S. and elsewhere.ENVIRONMENT: Burning Energy to Produce It
Everything about the Alberta oil sands development is impossibly big. Monster-sized trucks and giant excavators are carving up hundreds of square kilometres of land, thousands of kilometres of pipelines and roads have been laid, and millions of litres of water are being super-heated to process millions of tonnes of rock and sand.US-MEXICO: Biodiversity Has No Use for Walls
Scientists fear that attempts to seal the border between Mexico and the United States will have a big impact on wildlife and the region's fragile and unique ecology.
Mega-Project Scrapes the Bottom of the Oil Barrel
Extracting oil from Alberta’s tar sands generates greenhouse gas emissions and destroys forests and wetlands. The activity’s health and social impact is one of Canada’s most pressing environmental issues.ENVIRONMENT: Oil Production Strains Parched Landscape
Money, energy and water are the three key ingredients that have made it possible to ship a million barrels of oil a day from northern Alberta's oil sands to the United States and other markets. Incredible quantities of those three ingredients have been used so far, and much more will be needed for production to triple in the next 15 years.BIODIVERSITY: Scientists Warn of Species Holocaust
The world's accelerating biodiversity crisis requires a new international coordinating mechanism to provide a united, authoritative scientific voice that can inform government decision-making internationally, experts say.ENVIRONMENT-CANADA: Transforming the Northern Landscape
Over much of northern Canada, there is little more than trees, rocks, lakes and wetlands. But in northeastern Alberta, the landscape is changing dramatically as strip mining peels off the forest and soil to reach a molasses-like viscous oil mixed with sand and clay 40 to 60 metres below the surface.ENVIRONMENT: Mega-Project Scrapes the Bottom of the Oil Barrel
Thousands of square kilometres of tar-laden soil and sand underlying Canada's boreal forests are being gobbled up to feed an insatiable appetite for oil in the U.S. and elsewhere.
Biodiversity Has No Use for Walls
Construction of a wall along the border would speed up the deterioration of the ecosystems on the Mexico-U.S. border, warn experts.ENVIRONMENT: Ailing Reefs Face New Threat of Acidity
Climate change is making the world's oceans more acidic, seriously endangering marine ecosystems, including coral reefs.HEALTH: Pre-Pandemic Vaccine at the Forefront in Bird Flu Fight
Some 17 countries are hard at developing experiments ultimately aimed at preventing the spread of bird flu amongst humans. So far, avian influenza has killed 120 people. The rapid production of effective, low-cost vaccines will not prevent a pandemic from happening, but could sharply reduce its impact, say experts.
Pre-Pandemic Vaccine at the Forefront in Bird Flu Fight
Scientists around the globe are working around the clock in search of vaccines that could improve the human immunological response to a potential flu pandemic.FILM: Setting the Record Straight on Global Warming
Former U.S. Vice President Al Gore's documentary on global warming, "An Inconvenient Truth", is filling theatres across North America - and gets the science right, according to climate experts.BRAZIL: Soy Exporters in Greenpeace’s Sights
Financed by huge U.S. agribusiness corporations like Cargill, soybean farming is now one of the primary drivers of deforestation in the Brazilian Amazon, charge activists from the environmental watchdog group Greenpeace, which is leading an international campaign against unregulated, unsustainable soybean cultivation.DEVELOPMENT: Scientific Diaspora Could Ease Brain Drain
Many expatriate scientists and medical professionals who work in Canada want to contribute their skills to their native developing countries - all that is lacking are mechanisms to help them do so without permanently returning to their country of origin, reports a study to appear Friday in Science magazine.« Previous Page — Next Page »
