New Research Will Help Shed Light on Role of Amazon Forests in Global Carbon Cycle

Berkeley Lab scientists devise new tools for detecting previously unknown tree mortality.

The Earth’s forests perform a well-known service to the planet, absorbing a great deal of the carbon dioxide pollution emitted into the atmosphere from human activities. But when trees are killed by natural disturbances, such as fire, drought or wind, their decay also releases carbon back into the atmosphere, making it critical to quantify tree mortality in order to understand the role of forests in the global climate system. Tropical old-growth forests may play a large role in this absorption service, yet tree mortality patterns for these forests are not well understood.

Now scientist Jeffrey Chambers and colleagues at the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) have devised an analytical method that combines satellite images, simulation modeling and painstaking fieldwork to help researchers detect forest mortality patterns and trends. This new tool will enhance understanding of the role of forests in carbon sequestration and the impact of climate change on such disturbances. (more…)

IBM Delivers New Services to Help Clients Move Enterprise Applications to the Cloud

Financial, healthcare, government and electronics clients tap IBM SmartCloud Enterprise+;
IBM SmartCloud for SAP Applications now available globally

ARMONK, N.Y. – 29 Jan 2013: IBM today announced global availability for its cloud service on five continents—plus a new center opening in Spain—based on its industry-leading sourcing business to host SAP® applications and other core operations. Now clients can turn to cloud computing for enterprise applications while reducing the overall cost of IT and at the same time, expanding online access and investing in innovative analytics, social business and mobile computing.

Many organizations are eager to leverage the economic advantages of cloud computing to run their critical applications on the cloud. These applications require deep technical expertise, around-the-clock customer service, tight security and ongoing maintenance – features typically found in IT sourcing arrangements but not in the “one-size-fits-all” model of self-service clouds.

NASA’s Galex Reveals the Largest-Known Spiral Galaxy

PASADENA, Calif. — The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest known spiral, based on archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission, which has since been loaned to the California Institute of Technology in Pasadena.

Measuring tip-to-tip across its two outsized spiral arms, NGC 6872 spans more than 522,000 light-years, making it more than five times the size of our Milky Way galaxy. (more…)

Argentina Ranks First in Worldwide Desktop Social Networking Engagement at Nearly 10 Hours per Visitor Each Month

Analysis of Social Networking in Latin America Shows LinkedIn Grabbing #2 Position with35 Million Monthly Visitors

Santiago, Chile, December 20, 2012 – comScore, a leader in measuring the digital world, today released an analysis of social networking activity in Latin America, which found that Argentina and Brazil led as the most engaged social networking markets worldwide with visitors spending an average of near 10 hours on social networking sites in November 2012. The study also found that LinkedIn, which has grown strongly in the past year due to both organic growth and the acquisition of Slideshare.net, is now the second most visited social network in Latin America.

Environmental Cost of Agriculture: Soil Determines Fate of Phosphorous

Brazil’s soybean yields have become competitive with those of the United States and Argentina, but the soil demands a lot of phosphorous, which is not renewable. In the United States, meanwhile, historical applications of the fertilizer have polluted waterways. What accounts for these problems? It’s the soils, according to a new study comparing agriculture in the three countries.

PROVIDENCE, R.I. [Brown University] — Just 20 years ago, the soils of the Amazon basin were thought unsuitable for large-scale agriculture, but then industrial agriculture — and the ability to fertilize on a massive scale — came to the Amazon. What were once the poorest soils in the world now produce crops at a rate that rivals that of global breadbaskets. Soils no longer seem to be the driver — or the limiter — of agricultural productivity. But a new Brown University-led study of three soybean growing regions, including Brazil, finds that soils have taken on a new role: mediating the environmental consequences of modern farming.

World’s Most Powerful Digital Camera Begins Hunt for Dark Energy

Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has captured and recorded it for the first time.

That light may hold within it the answer to one of the biggest mysteries in physics: Why the expansion of the universe is speeding up. (more…)

Salt Seeds Clouds in the Amazon Rainforest

It’s morning, deep in the Amazon jungle. In the still air innumerable leaves glisten with moisture, and fog drifts through the trees. As the sun rises, clouds appear and float across the forest canopy … but where do they come from? Water vapor needs soluble particles to condense on. Airborne particles are the seeds of liquid droplets in fog, mist, and clouds.

To learn how aerosol particles form in the Amazon, Mary Gilles of the Chemical Sciences Division at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and David Kilcoyne of the Lab’s Advanced Light Source (ALS) worked with Christopher Pöhlker of Germany’s Max Planck Institute for Chemistry (MPIC) as part of an international team of scientists led by MPIC’s Meinrat Andreae and Ulrich Pöschl. They analyzed samples of naturally formed aerosols collected above the forest floor, deep in the rainforest. (more…)
