TREATING CATTLE WITH INSECTICIDE - A NEW APPROACH FOR MALARIA CONTROL IN SOUTH ASIA (p 1837)
Insecticide treatment of livestock could be a new, cost-effective malaria-control strategy in south Asia, conclude authors of a study in this week's issue of THE LANCET. Indoor spraying of houses with insecticide - the standard method of malaria control in south Asia - is becoming prohibitively expensive to implement and new approaches are... view more...

Scientists demonstrate feasibility of preventing malaria parasite from becoming sexually mature
Researchers have demonstrated the possibility of preventing the human malaria parasite, Plasmodium falciparum, which is responsible for more than a million malaria deaths a year, from becoming sexually mature. view more (2008-06-03)
Passenger Screening Advised To Cut Risk Of Importing Drug-Resistant Malaria To Africa
Imported resistance has rendered ineffective the two affordable malaria drugs which have been the mainstay of malaria treatment in Africa for forty years, according to experts writing today in the journal Science. Scientists from the London School of Hygiene and Tropical Medicine and colleagues from institutions in the USA, South Africa and... view more... (2004-08-16)
Monkey malaria widespread in humans and potentially fatal
A potentially fatal species of malaria is being commonly misdiagnosed as a more benign form of the disease, thereby putting lives at risk. view more (2008-01-16)
New hope for advances in treating malaria
Researchers at the University of Leeds have developed chemicals which kill the most deadly malaria-causing parasite, Plasmodium falciparum -- including those resistant to existing drugs. view more (2009-04-22)
Malnutrition and obesity increasingly co-exist in global community
While nutritional status has improved worldwide over the past fifty years, new nutrition-related problems have also emerged. view more (2005-08-04)
Why the Amazon rainforest is so rich in species
Tropical areas of south and central America such as the Amazon rainforest are home to some 7500 species of butterfly compared with only around 65 species in Britain. view more (2005-12-06)
Diverse tropical forests defy metabolic ecology models
As global change accelerates, quantifying the role of forests in the carbon cycle becomes ever more urgent. Modelers seek simple predictors of forest biomass and carbon flux. view more (2006-04-24)
Temperate Forests Could Worsen Global Warming
Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. view more (2005-12-07)
Problem of emerging infectious diseases likely to worsen
Emerging infectious diseases pose a global threat to human and animal health, and the problem is likely to worsen, warns an expert in this week's BMJ. view more (2005-11-28)
Flights reveal intriguing information about ice particles in clouds
In the clouds above Darwin, Australia, pilots guided by a team of international climate scientists are now one week into a series of carefully orchestrated flights to obtain key in situ data about tropical clouds. view more (2006-02-06)
Marine pathogens spread much faster than their terrestrial counterparts
It has become increasingly clear that pathogen epidemics are as significant a component of marine systems as they are in terrestrial systems. At an National Center for Ecological Analysis and Synthesis (NCEAS) working group on Diseases in the Ocean, McCallum, Harvell and Dobson collated data on epidemic spread from both terrestrial and marine... view more...

"Live fast, die young" applies to forests, too.
Forests provide humans with economically important and often irreplaceable products and services, and affect global climate by acting as sources and sinks of heat-trapping carbon dioxide. Yet the possible responses of forests to ongoing environmental changes are poorly understood. In the most recent issue of Ecology Letters, Stephenson and van... view more... (2005-04-19)
NASA study solves ocean plant mystery
A NASA-sponsored study shows that by using a new technique, scientists can determine what limits the growth of ocean algae, or phytoplankton, and how this affects Earth's climate. view more (2006-09-01)
Human activities are boosting ocean temperatures in areas where hurricanes form, new study finds
Rising ocean temperatures in key hurricane breeding grounds of the Atlantic and Pacific oceans are due primarily to human-caused increases in greenhouse gas concentrations. view more (2006-09-12)
Limpets reveal possible fate of cold-blooded Antarctic animals
A limpet no bigger than a coin could reveal the possible fate of cold-blooded Antarctic marine animals according to new research published this week in The Journal of Experimental Biology. view more (2007-07-24)
Monster hurricanes
New research calls into question the linkage between major Atlantic hurricanes and global warming. That is one of the conclusions from a University of Virginia study to appear in the May 10, 2006 issue of the journal Geophysical Research Letters. view more (2006-05-10)
Century of data shows intensification of water cycle but no increase in storms or floods
A review of the findings from more than 100 peer-reviewed studies shows that although many aspects of the global water cycle have intensified, including precipitation and evaporation, this trend has not consistently resulted in an increase in the frequency or intensity of tropical storms or floods over the past century. view more (2006-03-16)
Tropical rainforest nutrients linked to global carbon dioxide levels
Extra amounts of key nutrients in tropical rain forest soils cause them to release more carbon dioxide into the atmosphere, according to research conducted by scientists at the University of Colorado (CU)—Boulder. view more (2006-06-21)
Amazon rainforest greens up in the dry season
The Amazon rainforest puts on its biggest growth spurt during the dry season, according to new research. view more (2006-03-21)
