Global malaria map key weapon in fight against malaria, scientists say
12-04-2006 · EurekAlert!For the first time in almost forty years, researchers are creating a global map of malaria risk. The Malaria Atlas Project, or MAP, will help identify populations at particular risk and predict the impact of the disease, allowing health resources to be targeted at those areas most at risk.

- Global malaria map key weapon in fight against malaria, scientists say
12-04-2006 · EurekAlert!
Information on the global burden of malaria remains the subject of "best guesses," and as a result resource allocation for malaria control remains "driven by perceptions and politics, rather than an objective assessment of need," say two prominent malaria researchers in PLoS Medicine.

- Identification of carbon dioxide receptors in insects may help fight infectious disease
12-13-2006 · EurekAlert!
Mosquitoes use the carbon dioxide people exhale as a way to identify a potential food source. But when they bite, they can pass on a number of dangerous infectious diseases, such as malaria and yellow fever. Now, reporting in Nature, Leslie Vosshall's laboratory at Rockefeller University has identified the two molecular receptors in fruit flies that help these insects detect carbon dioxide. The findings could prove to be important against the fight against global infectious disease.

- Targeting the adrenal gland could be key strategy against heart failure, Jefferson scientists show
02-18-2007 · EurekAlert!
Scientists have staved off heart failure in animals by using gene therapy to shut down the adrenal gland's excessive output of fight or flight hormones such as epinephrine and norepinephrine, which forces the heart to pump too hard. Such a novel approach -- targeting the adrenal gland in addition to the heart -- provides a potential new strategy against heart failure, and could lead to a new class of drugs.

- Report: African, Asian, Latin American farm animals face extinction
09-03-2007 · EurekAlert!
With the world's first global inventory of farm animals showing many breeds of African, Asian, and Latin American livestock at risk of extinction, scientists from the Consultative Group on International Agricultural Research today called for the rapid establishment of genebanks to conserve the sperm and ovaries of key animals critical for the global population's future survival.

- Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution
05-15-2007 · EurekAlert!
Recent studies by Woods Hole Research Center scientists demonstrate that during years of severe drought, tropical rainforest fires can double emissions from tropical forests. Now, an international team of forest and climate researchers has found that halving deforestation rates by mid-century would account for 12 percent of total emissions reductions needed to keep concentrations of heat-trapping gases in the atmosphere at safe levels. This work is profiled in a recent issue of Science.

- Record warm summers cause extreme ice melt in Greenland
01-15-2008 · EurekAlert!
An international team of scientists, led by Dr. Edward Hanna at the University of Sheffield, has demonstrated that recent warm summers have caused the most extreme Greenland ice melting in 50 years. The new research provides further evidence of a key impact of global warming and helps scientists place recent satellite observations of Greenland's shrinking ice mass in a longer-term climatic context.

- The insides of clouds may be the key to climate change
02-17-2007 · EurekAlert!
As climate change scientists develop ever more sophisticated climate models to project an expected path of temperature change, it is becoming increasingly important to include the effects of aerosols on clouds, according to Joyce E. Penner, a leading atmospheric scientist at the University of Michigan.

- Obtaining valid consent for doing large genetic studies in developing countries
04-23-2007 · EurekAlert!
Genetic research has the potential to improve global health by discovering what makes people susceptible or resistant to certain diseases, and what causes the diseases themselves, thereby guiding prevention efforts. Genetic studies, for example, are providing clues for scientists working on vaccines against HIV, malaria and TB. But it is crucial, say Dave Chokshi and colleagues in a policy paper in PLoS Medicine, to ensure that those who choose to participate in such research have given their fully informed consent.

- Rain forest protection works in Peru
08-09-2007 · EurekAlert!
A new regional study shows that land-use policies in Peru have been key to tempering rain forest degradation and destruction in that country. Scientists at the Carnegie Institution's Department of Global Ecology led an international effort to analyze seven years of high-resolution satellite data covering most (79 percent) of the Peruvian Amazon for their findings.
