Permafrost soil metagenome study in Discover

What’s the News: Melting  permafrost in a warming world could mean lots of greenhouses gasses, especially methane, released into the atmosphere. But it also means an unusual community of soil bacteria coming out of hibernation, so to speak. A new study looks at what those permafrost microbes do, exactly, as their environment warms up.

Permafrost soil metagenome study in Time

One of those wild cards is the 1,672 billion tonnes of carbon equivalent trapped in the form of methane in the Arctic permafrost, the soils kept frozen by the far North’s extreme temperatures. Methane is a powerful greenhouse gas—it has 20 times the warming effect of carbon dioxide—and the total amount of carbon equivalent in… [Read More]

Permafrost soil metagenome study on LiveScience

“Nobody has looked at what happens to microbes when the permafrost thaws,” said Janet Jansson, a senior staff scientist at Lawrence Berkeley National Laboratory in California. She led a study that recorded what happened when chunks of Alaskan permafrost thawed for the first time in 1,200 years. Read more on LiveScience [Read More]

Permafrost soil metagenome study in UK Press Association

At the testing laboratories, US researchers extracted almost 40 billion elements of raw DNA, reflecting high microbial diversity in the soil.The scientists were also able to piece together the genetic code, or genome, of a previously unknown methane-producing “methanogen” that was present in large numbers. Reporting their findings in an early online edition of the journal… [Read More]

Permafrost soil metagenome study in GenomeWeb

“Currently in climate models, it’s not really taken into account adequately what the microorganisms are doing,” senior author Janet Jansson, a researcher affiliated with the Lawrence Berkeley National Laboratory and the US Department of Energy’s Joint Genome Institute, told GenomeWeb Daily News. “The hope is to get enough information at the microscopic level that we’ll have… [Read More]

JGI Science @ the Lesher in The Oakland Tribune

The researchers, who will speak Monday evening at the Lesher Center for the Arts in Walnut Creek, are working with the Joint Genome Institute in Walnut Creek, a federal facility for genetic sequencing of microbes and other life-forms. The terrestrial ecosystem, meaning everything on land — from plants to soil and other geological features —… [Read More]

Looking beyond biotech companies for microbe-based biofuels

If you’re feeling ill trying to keep up with all the strange biofuel news these days, you might want to have some lab tests run. You could have a form of E. coli poisoning, a cyanobacteria outbreak, or maybe you accidentally ingested some highly toxic fire moss or perhaps bumped into a desert locust –… [Read More]
