The fight against malaria, a plague that kills at least one person every 30 seconds in sub-Saharan Africa, was boosted this week by news that scientists have decoded the genetic blueprint of the malaria parasite and the mosquito that spreads it.
Developing a handful of biotechnologies to prevent and treat diseases could save millions of lives in developing countries each year, say the authors of a study released Monday in Nature Biotechnology magazine.

Failure to invest in scientific research in developing countries is undermining efforts to fight poverty, disease and environmental destruction, says renowned economist Jeffrey Sachs.
Coastal and marine ecosystems, already stressed by human development, pollution and over-fishing, are going to face significant pressure from climate change, says a new report from the Pew Centre on Global Climate Change.

New genetic tests suggest that it may be more difficult than believed to develop an effective vaccine to fight malaria, leaving the controversial pesticide DDT as the most effective killer of the parasite that causes the disease.
Canadian farmers on tiny, green Prince Edward Island are stacking bales of their fresh-cut hay onto rail cars and shipping them 5,000 kilometres to feed hungry cattle in dusty Alberta and Saskatchewan, suffering their worst droughts in history.
A biotechnology approach to controlling African farmers' persistent enemy - witchweed - may be getting the upper hand on more "ecological" solutions to the problem, thanks to funding from Western agencies.
Genetic research could help save millions of lives in poor countries by helping defeat diseases like malaria, tuberculosis, and HIV/AIDS, says the World Health Organisation (WHO). Some experts say faith in the genomic industry -- with its emphasis on high technology and profits -- is misplaced.
Biotechnology companies intend to foster the development of medicines for the world's poorest people and ensure that developing countries benefit when local plants or remedies are used for new drugs. In exchange, they want open markets, harmonised regulations, and respect for their intellectual property rights.
Some of the world's biggest mining and metals corporations publicly committed to sustainable development at a Global Mining Initiative Conference here this week. Activists greeted the promise with scepticism.
The battle over who should control the planet's biological resources is heating up. While activists and developing nations insist on more local control, the world's trade body wants all countries to adopt a U.S.-style patent system.
A water filter used in more than 50 developing countries could have saved Canadian lives and might still hold the key to preventing outbreaks of water-borne disease, says the inventor of the device.
Canada's health department has launched a programme to monitor the health impacts of foods containing genetically modified (GM) ingredients, but experts and critics say sorting out the impacts, if any, will be extremely difficult unless the products are labelled.
