Can light-colored rooftops and roads really curb carbon emissions and combat global climate change? The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.

In March and early April 2009, a new, swine-origin 2009-H1N1 influenza A virus emerged in Mexico and the United States. During the first few weeks of surveillance, the virus spread by human-to-human transmission worldwide to over 30 countries. On June 11, 2009, the World Health Organization (WHO) raised the worldwide pandemic alert level to Phase 6 in response to the ongoing global spread of the novel influenza A (H1N1) virus. By October 30, 2009, the H1N1 influenza A had spread to 191 countries and resulted in 5,700 fatalities. A national emergency was declared in the United States and the swine flu joined SARS and the avian flu as pandemics of the 21st century. Vaccination is currently available, but in limited supply, and with a 60 percent effectiveness rate against the virus.

During a visit to Europe one feels its so cold at time of the year. I dint even bring sufficient clothing to face the low temperatures in May in central europe. India is facing 47 degree in Alwar , a place known for the tiger reserve and dense forests in the vicinity of Aravalli hills . The barren hills will work like fireplace and emit all the heat for the population. Jaipur is also surrounded by hills on all the sides and will meet same fate. Stop thinking that water is provided by Governments .

Alexander Skupin and Martin Falcke The universality of Ca as second messenger in living cells is achieved by a rich spectrum of spatiotemporal cellular concentration dynamics. Ca release from internal storage compartments plays a key role in shaping cytosolic Ca signals. Deciphering this signaling mechanism is essential for a deeper ...

I am such a nerd. This new map of Mars just brought tears to my eyes. Honestly. Mars Odyssey has been in orbit since October 2001 -- nearly nine years -- circling Mars about twelve times a day. That's more than 40,000 orbits it's racked up. The THEMIS camera has been working pretty much continuously since mapping started in January 2002, stopping only when the orbiter went into safe mode. It's taken all those years, and a total of 21,000 ....

WASHINGTON (Reuters) - Melting glaciers, more humid air and eight other key indicators show that global warming is undeniable, scientists said on Wednesday, citing a new comprehensive review of the last decade of climate data.

What you might have thought you knew about climate change, but didn't.

China and South Korea have invested heavily in environmental stimulus projects. Other G20 countries need to deliver on their sustainability promises to save both the planet and the economy, says Edward Barbier.

Global companies are betting Indonesia will become Asia's next big consumer market after China and India—in part because of booming second-tier cities fueled by sales of coal, gas and palm oil.

"Goodness," thought Alice to herself, "what a very strange place this is." Only a moment before, the sun had been shining brightly and Alice was quite comfortable in her pinafore. Now the snow was falling furiously, and lay on the ground as high as her waist. "I shall catch my death of cold," she said to no one in particular. No sooner had she spoken than the sun burst through the clouds and the snow melted away. Soon she was standing up to her ankles in water.

Scientists have calculated that it actually makes sense to start intentional fires to keep down debris and undergrowth. Even though these prescribed fires do put carbon into the atmosphere, the scientists calculate it's less than what would go up in big wildfires.» E-Mail This     » Add to Del.icio.us

Although clinicians are always looking for objective ways to measure therapeutic success, most patients understandably consider quality of life to be the most important outcome of therapy. This viewpoint is particularly valid for patients with atrial fibrillation (AF), because few interventions have been shown to

SAN FRANCISCO — The first ever global map of Mercury was released here Tuesday at the American Geophysical Union meeting.
The map combines new observations from the Messenger spacecraft with earlier images captured by Mariner 10 in the 1970s.
Messenger completed the last of its three flybys of the planet on September 29th. The release of the map marks a new phase of the mission for the spacecraft, which will now orbit the sun’s innermost planet for a year.
The U.S. Geological Survey built the map from 917 images of variable resolution and lighting conditions, but sophisticated software was able to match up planetary features from different images to create the near seamless mosaic.

Natural ecosystems and biodiversity must be made a bulwark against climate change, not a casualty of it, argue Will R. Turner, Michael Oppenheimer and David S. Wilcove.

Various "psychologies" bubble up as people seek to digest possible global doom.
