Scientists to track impact of Asian dust and pollution on clouds, climate change
Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America.   view more (2007-04-19)

Promising treatment for post-traumatic stress disorder sleep disturbances
For sufferers of Post Traumatic Stress Disorder (PTSD), sleep disturbances are among the most treatment-resistant symptoms and can lead to drug and alcohol abuse and even suicide.   view more (2007-04-19)

A change in the wind
Climate model simulations for the 21st century indicate a robust increase in wind shear in the tropical Atlantic due to global warming, which may inhibit hurricane development and intensification.   view more (2007-04-18)

Global Fund must fund salaries of health workers to deliver HIV, TB and malaria treatments
In this week's PLoS Medicine, a team of international health experts issue a bold call to the Global Fund to Fight AIDS, TB, and Malaria: fund the salaries of health workers or else risk a situation in which medicines for these three diseases are made available in poor countries but there are no... view more (2007-04-17)

LSU professor helps India prepare for impact of global warming
Growing concern over the potential impact of global warming has spurred action from Louisiana to India.   view more (2007-04-16)

New analysis says eradicating polio a better option than extended control of the disease
Concerns about the high perceived costs of eradicating the relatively low number of polio cases worldwide have led to recent suggestions that it is time to shift from a goal of eradication to control—abandoning eradication and allowing wild poliovirus to continue to circulate, which... view more (2007-04-12)

FSU anthropologist finds earliest evidence of maize farming in Mexico
A Florida State University anthropologist has new evidence that ancient farmers in Mexico were cultivating an early form of maize, the forerunner of modern corn, about 7,300 years ago-1,200 years earlier than scholars previously thought.   view more (2007-04-10)

Trees to offset the carbon footprint?
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming.   view more (2007-04-10)

Tropical forests — Earth's air conditioner
Planting and protecting trees—which trap and absorb carbon dioxide as they grow—can help to remove carbon dioxide from the atmosphere.   view more (2007-04-10)

Latest IPCC report highlights need for integrated climate/human behavior models
Adapting to the global climate change impacts outlined in the IPCC's Working Group 2 Report, "Climate Change 2007: Impacts, Adaptation and Vulnerability", will require new evaluation tools to help choose the best way forward, according to the International Geosphere-Biosphere Programme... view more (2007-04-09)

Scientists must improve communication tactics, Science article proclaims
Seed Washington Correspondent Chris Mooney and American University professor and ScienceBlogs contributor Dr. Matthew Nisbet are co-authors of a provocative new article in Science entitled "Framing Science." The article suggests that as the 2008 election approaches, scientists should... view more (2007-04-06)

The global carbon budget — proper accounting means paying attention to inland waters
Life as we know it, from the most basic microbes to our human neighbors, is carbon based. By investigating how carbon cycles through ecosystems, scientists can learn valuable information about food chains, nutrient cycling, and productivity.   view more (2007-04-04)

Weighing the financial risks of nuclear power plants
Enticed by the gleam of government subsidies, many companies are rushing to invest in nuclear power, expecting that new technology and safer reactors will make them as good an investment as other types of power plants.   view more (2007-04-04)

MIT's ocean model precisely mimics microbes' life cycles
Scientists at MIT have created an ocean model so realistic that the virtual forests of diverse microscopic plants they "sowed" have grown in population patterns that precisely mimic their real-world counterparts.   view more (2007-03-30)

Warm winter also in the Arctic
Central Europe is not the only place where the past, warm winter has caused record temperatures. Unusually mild temperatures also prevented ice formation in the Arctic, specifically in the region around Spitsbergen.   view more (2007-03-30)

Greenhouse gas effect consistent over 420 million years
New calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years, according to an article in Nature by geologists at Yale and Wesleyan Universities.   view more (2007-03-29)

Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.   view more (2007-03-29)

Himalayan glacier melting observed from space
The Himalaya, the "Roof of the World", source of the seven largest rivers of Asia are, like other mountain chains, suffering the effects of global warming.   view more (2007-03-28)

Biologists Produce Global Map of Plant Biodiversity
Biologists at the University of California, San Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on... view more (2007-03-21)

ESA's Medspiration project branches out to support biodiversity
Maps of the sea surface temperature around Galapagos Islands and Cocos Island in the Pacific Ocean are being produced daily and are available online in full resolution in near-real time as part of the Medspiration project, an ESA-funded effort to represent the most reliable temperature of the seas... view more (2007-03-20)

Global 'sunscreen' has likely thinned, report NASA scientists
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground.   view more (2007-03-19)

Crops feel the heat as the world warms
Over a span of two decades, warming temperatures have caused annual losses of roughly $5 billion for major food crops, according to a new study by researchers at the Carnegie Institution and Lawrence Livermore National Laboratory.   view more (2007-03-16)

Global temperature — politics or science?
The entire debate about global warming is a mirage. The concept of 'global temperature' is thermodynamically as well as mathematically an impossibility, says professor at The Niels Bohr Institute, University of Copenhagen, Bjarne Andresen who has analyzed this hot topic in collaboration with... view more (2007-03-16)

Warming oceans threaten Antarctic glaciers
Scientists have identified four Antarctic glaciers that pose a threat to future sea levels using satellite observations, according to a study published in the journal Science.   view more (2007-03-16)

Transported Black Carbon a Significant Player in Pacific Ocean Climate
Soot and other particulate pollution from Asian sources make up more than 75 percent of black carbon transported at high altitudes, according to a Scripps Institution of Oceanography, UC San Diego-led study.   view more (2007-03-15)
