Berkeley Lab scientists develop new method for evaluating short-lived pollutants.

New research from Lawrence Berkeley National Laboratory (Berkeley Lab) has found that levels of methane—a potent greenhouse gas emitted from many man-made sources, such as coal mines, landfills and livestock ranches—are at least one-and-a-half times higher in California than previously estimated.

Working with scientists from the National Oceanic and Atmospheric Administration (NOAA) Berkeley Lab scientists Marc L. Fischer and Seongeun Jeong combined highly accurate methane measurements from a tower with model predictions of expected methane signals to revise estimated methane emissions from central California. They found that annually averaged methane emissions in California were 1.5 to 1.8 times greater than previous estimates, depending on the spatial distribution of the methane emissions. (more…)

Mapping Volcanic Heat on Io

A new study finds that the pattern of heat coming from volcanoes on Io’s surface disposes of the generally-accepted model of internal heating. The heat pouring out of Io’s hundreds of erupting volcanoes indicates a complex, multi-layer source. These results come from data collected by NASA spacecraft and ground-based telescopes and appear in the June issue of the journal Icarus.

A map of hot spots, classified by the amount of heat being emitted, shows the global distribution and wide range of volcanic activity on Io. Most of Io’s eruptions dwarf their contemporaries on Earth. (more…)

New Media Driving Occupy Movement, Prof Says

Lacking structured leadership, a single spokesperson and even a clear message, the Occupy movement has grown through the use of personal media and new technologies, sustained by participants’ own network of contacts and willingness to dive into the political fray, says a UCLA information studies professor who studies the different ways media and technology shape society and culture.

Throughout the life of the Occupy movement, dynamic social and technological factors have helped shape the character and effect of demonstrations and fueled the coverage the movement has received in the mainstream press. And Professor Leah A. Lievrouw sees the day-to-day use of mobile devices as a defining element of Occupy’s activism that has helped organizers gain momentum and support as well as ignite social, cultural and economic change.

*New map of the genetic code of endangered orangutans yields important new conservation tools and insights into evolution*

For the first time, scientists have mapped the genome–the genetic code–of orangutans. This new tool may be used to support efforts to maintain the genetic diversity of captive and wild orangutans. The new map of the orangutan genome may also be used to help improve our understanding of the evolution of primates, including humans.

Partially funded by the National Science Foundation, the orangutan study appears in the Jan. 27 issue of Nature. It was conducted by an international team of scientists led by Devin P. Locke of the Genome Center at Washington University. (more…)

Some 55% of tropical forests are negatively affected by land use practices and deforestation worldwide. But the ability to penetrate the canopy to see what’s going on has been lacking until now.

Global Ecology’s Greg Asner’s group has developed new airborne methods to peer through the canopy to measure and map, in beautiful 3-D, the underlying vegetation, degradation and deforestation, and the amount of carbon stored and emitted in these forests. (more…)
