Metamaterials shine bright as new terahertz source
Terahertz waves are used in information, communication, processing, and data storage technologies, yet few terahertz sources are available due to the limitations of natural materials. Scientists discovered an efficient terahertz emission from two-dimensional arrays of gold split-ring resonator metamaterials, which allow design and use of light-matter interactions at a fundamental level. This discovery opens new ways to use such materials.

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

Intertwining of superconductivity and magnetism
Experiments reveal nearly static, spatially modulated magnetism in a copper-oxide superconductor. Because static magnetism and superconductivity prefer not to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory. This study will assist in developing a predictive theory for high-temperature superconductivity that can assist in the design and discovery of improved superconductors.

Competition not concentration matters when forming cloud-influencing aerosols
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
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.

Compact light source improves CT scans
A new study shows that the recently developed Compact Light Source -- a commercial X-ray source with roots in research and development efforts at the Department of Energy's SLAC National Accelerator Laboratory -- enables computer tomography scans that reveal more detail than routine scans performed at hospitals today. The new technology could soon be used in preclinical studies and help researchers better understand cancer and other diseases.

New mathematical method enhances hydrology simulations
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.

Model captures how nitrogen limitation affects hydrological processes
Rising atmospheric levels of carbon dioxide act as a fertilizer for plants, speeding their growth and altering how they use water and interact with the climate. However, an insufficient supply of nitrogen can limit the rapid growth caused by increased carbon dioxide. Researchers adapted the Community Land Model to represent how nitrogen limitation affects plant growth.

EMSL's Special Science Call for Proposals ran from mid-April through September and generated 23 accepted studies. The call challenged prospective users to submit high-impact research projects that took advantage of EMSL's technical resources including RadEMSL, the Quiet Wing microscopy and NanoSIMS capabilities, and HRMAC. The research associated with the call is progressing, and the projects will soon start delivering important scientific findings.

Ground control
The United Nations General Assembly declared 2015 the International Year of Soils. Soil is critical for food production and climate regulation. It's a complex underground ecosystem of organisms that process decaying debris to enrich the land as well as store and release carbon into the atmosphere. However, human activity and changing climate are impacting this environmental system. Scientists working at EMSL are trying to understand the complexities of soil to develop better sustainable land management to protect it.
