The difference between a mole and shrew is in their SOX

The family of small insectivores, Talpidae, includes the moles, shrew moles, and aquatic desmans. New research published in BioMed Central's open access journal EvoDevo has found that the enlargement of moles' digging front ...

Comparison with observations shows cloud simulations improving

Climate projections, such as those used by the Intergovernmental Panel on Climate Change, rely on models that simulate physical properties that affect climate, including clouds and water vapor content. Clouds and water vapor ...

Dams impact carbon dynamics in U.S. rivers

Dissolved organic carbon (DOC)—which leaches into freshwater systems from plants, soils, and sediments, and from other detritus present in the water itself—is the major food supplement for microorganisms and plays ...

The random walk of pollutants through river catchments

River catchments play critical roles in regional economies and in the global economy. In addition, rivers carry large volumes of nutrients, pollutants, and several other forms of tracers into the ocean. An intricate system ...

Atmospheric CO2 drove climate change during longest interglacial

Known as the marine isotope stage 11 (MIS 11), the interglacial period centered around 400,000 years ago was the longest and possibly the warmest interglacial in the past 0.5 million years. Because the orbital configurations, ...

Turbulent forces within river plumes affect spread

When rivers drain into oceans through narrow mouths, hydraulic forces squeeze the river water into buoyant plumes that are clearly visible in satellite images. Worldwide, river plumes not only disperse freshwater, sediments, ...
