Permafrost soil metagenome study in Wired UK

As permafrost thaws, trapped frozen organic matter becomes accessible for microbes to degrade, releasing greenhouse gases as a byproduct. Understanding what sorts of microbes are in the ice is key to predicting the impact of the melting of permafrost soils.The US Department of Energy has teamed up with the Joint Genome Institute, the Earth Sciences Division of… [Read More]

Permafrost soil metagenome study on Voice of America

Lead author Janet Jansson, senior scientist at the Lawrence Berkeley National Laboratory in California says the trapped microorganisms in permafrost are still active. Jansson and colleagues at the U.S. Geological Survey and the Joint Genome Institute at the Department of Energy set out to identify microbes in permafrost and find out what they would do once… [Read More]

Permafrost soil metagenome study on Medill News Reports

Microbes frozen for thousands of years can spring to life and digest the carbon to release heat-trapping gases into the atmosphere, amplifying warming and melting. Scientists can’t yet predict how much of the carbon stored in Arctic permafrost will reach the atmosphere, but microbes could play a pivotal role. Read more on Medill Reports Chicago [Read More]

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 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]

DOE JGI science in the Washington Post

JGI director and geneticist Eddy Rubin is a pioneer in the field of “metagenomics,” the study of how the DNA in many creatures can work together to create ecosystems. Right now, he and his team are studying microbes that live in a cow’s rumen, the stomach-like organ that the animals use to break down grasses… [Read More]

A metagenomic approach to analyzing rice endophytes

During the call for 2012 proposals for the DOE JGI’s Community Sequencing Program, one of the areas of focus researchers were asked to consider was that of plant-microbe interactions. Microbes that live in plants or in the rhizosphere where plant roots and soil interact can play crucial roles in plant health. This is of particular… [Read More]

CSP 2012 announcement in GenomeWeb Daily News

The Department of Energy’s Joint Genome Institute has chosen 41 research projects out of 152 applicants to use its sequencing services under its 2012 Community Sequencing Program, JGI said Thursday.Researchers for this year’s CSP program, which provides the scientific community with access to JGI’s high-throughput sequencing technologies, proposed projects to study plant-microbe interactions, how microbes… [Read More]

Berkeley Lab Open House recap on Today at Berkeley Lab

At DOE JGI’s metagenomics of restored wetlands exhibit Most notable among the crowd of thousands was the number of youngsters who were in attendance. Families were enthralled by the terrific science, engineering, and operations efforts presented at the various booths. Read more at Today at Berkeley Lab [Read More]

Structural Analysis of Cow and Hoatzin Microbial Communities

Inside the guts of many animals, microbes break down the plant fibers ingested as part of their diet. These microbes are of interest to bioenergy researchers who want to learn from nature and apply these cellulosic degradation capabilities toward biofuel production. To this end, at the JGI, several sequencing projects have focused on the microbial… [Read More]
