Research to focus on microbes in peat moss

Sept. 12, 2018- 
Mention "peat moss" and many people will conjure up the curly brown plant material that gardeners use. "Oh, the thing you get at Home Depot" is a common reaction Joel Kostka receives when he mentions that he studies peat moss. His response: "Peat moss is a really cool plant that’s important to the global carbon cycle." The National Science Foundation has just awarded Georgia Tech, and...

Scientists now know the fate of the majority of Higgs bosons particles produced in the LHC

Aug. 29, 2018- 
At CERN, the Large Hadron Collider experiments ATLAS and CMS have taken a big step forward in the quest to understand how the Higgs boson enables fundamental particles to acquire mass. The team announced the discovery of the Higgs boson particle transforming into bottom quarks as it decays. This is predicted to be the most common way for Higgs bosons to decay, yet was a difficult signal to...

Four Lawrence Livermore National Laboratory (LLNL) researchers have been named Distinguished Members of Technical Staff (DMTS) for their extraordinary scientific and technical contributions to the Laboratory and its missions, as acknowledged by their professional peers and the larger community. Peter Beiersdorfer and Paul Springer of the Physical and Life Sciences Directorate, Robert Falgout...

Lab researchers find magnetic fields impact atmospheric circulation of gas giant planets

Aug. 9, 2018- 
Magnetic fields around a planet or a star can overpower the zonal jets that affect atmospheric circulation. New research by a Lawrence Livermore National Laboratory (LLNL) scientist and a collaborator from the Australian National University (ANU) provides a theoretical explanation for why self-organized fluid flows called zonal jets or "zonal flows" can be suppressed by the presence of a...

Using microbes to convert CO2 to natural gas

Aug. 6, 2018- 
Lawrence Livermore National Laboratory (LLNL), in collaboration with Southern California Gas Co. and Stanford University, are using microbes to convert carbon dioxide directly to renewable natural gas. The U.S. Department of Energy recently awarded the power-to-gas project $800,000. SoCalGas will provide co-funding of $400,000 in addition to $125,000 of seed funding it provided in 2017. Usi...
