New method relates Greenland ice sheet changes to sea-level rise

DOE/US Department of Energy

Climate models are not yet able to include full models of the Greenland and Antarctic ice sheets and to dynamically simulate how ice sheet changes influence sea level. Early schemes failed to accurately account for mass increase due to snowfall and mass loss due to snow melt. These changes depend on ice sheet elevation and region. A new method that includes the effects of elevation and region was developed.

US-CERN agreement paves way for new era of scientific discovery

DOE/US Department of Energy
Business Announcement

A new agreement between the United States and the European Organization for Nuclear Research (CERN) signed today will pave the way for renewed collaboration in particle physics, promising to yield new insights into fundamental particles and the nature of matter and our universe.

Office of Science selects 44 scientists to receive early career research program funding

DOE/US Department of Energy
Grant and Award Announcement

The Department of Energy's Office of Science has selected 44 scientists from across the nation -- including 17 from DOE's national laboratories and 27 from US universities -- to receive significant funding for research as part of DOE's Early Career Research Program.

Competition not concentration matters when forming cloud-influencing aerosols

DOE/US Department of Energy

Scientists discovered that nitrogen oxides cannot be assumed to have a linear effect on secondary organic aerosol formation, which influences cloud formation and other phenomena.

Heat's role in the Madden-Julian Oscillation

DOE/US Department of Energy

Tropical monsoons in Indonesia and floods in the United States are both provoked by the Madden-Julian Oscillation, a process that results in pulses of clouds and precipitation moving eastward around the globe. Despite the MJO's importance, global models often struggle to simulate the oscillation accurately. Researchers showed that MJO simulations are most sensitive to the existence of lower level heating in the atmosphere.

Genetics of wood formation

DOE/US Department of Energy

To begin to understand the complex genetic interactions that control a potential bioenergy crop, scientists built a robust high-throughput pipeline for studying the hierarchy of genetic regulation of wood formation using tissue-specific single cells known as protoplasts.

New mathematical method enhances hydrology simulations

DOE/US Department of Energy

Just as a racecar's engine needs the right fuel to get the best performance, so climate models need finely tuned parameters to accurately simulate the impacts of different technologies and policies. Led by researchers at Pacific Northwest National Laboratory, a team applied sophisticated mathematical solutions to fine tune the water and energy exchange parameters, numerical stand-ins for complex processes, to better simulate water and energy fluxes.

New path to loss-free electricity

DOE/US Department of Energy

Electric current flows without any resistance in a superconducting state thanks to a surprising redistribution of bonding electrons and the associated electronic and atomic behavior after substitution of some cobalt atoms for iron in barium iron arsenide.

Microbe produces ethanol from switchgrass without pretreatment

DOE/US Department of Energy

Scientists engineered a strain of a consolidated bioprocessing bacterium that efficiently breaks down biomass to produce ethanol without pretreatment.

Microbes disprove long-held assumption that all organisms share a common vocabulary

DOE/US Department of Energy

Some wild microorganisms reinterpret the instructions coded into their DNA. Short DNA segments that signal other organisms to stop are instead read as instructions to keep building.
