BACKGROUND: The wild grass Brachypodium distachyon has emerged as a model system for temperate grasses and
biofuel plants. However, the global analysis of miRNAs, molecules known to be key for eukaryotic gene regulation,
has been limited in B. distachyon to studies examining a few samples or that rely on computational...

NASA’s ICESat-2 satellite, which launched in 2018, carries the Advanced Topographic Laser Altimeter System (ATLAS), a green-wavelength, photon-counting lidar. While ICESat-2’s primary mission focuses on measurement of elevation of ice sheets, glaciers, sea ice, and vegetation, ATLAS has also proven remarkably effective at measurement of bathymetry, or water depths. However,...
Ammonia oxidation is the first and rate-limiting step in nitrification and is dominated by two distinct groups of microorganisms in soil: ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). AOA are often more abundant than AOB and dominate activity in acid soils. The mechanism of ammonia oxidation under acidic conditions has...

Satellite-derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the
shelf-open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these
exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well-defined
seasonal pattern of SSS during...
