In desert suburb, homes in homeowners' associations use less water, study finds.

A new study in Water Resources Research finds that in some areas, homeowners' associations are good for water conservation.

Antarctic lakes provide glimpse of ancient forest fires, modern human impacts

The perpetually ice-covered lakes in Antarctica's McMurdo Dry Valleys preserve the dissolved remnants of black carbon from thousand-year-old wildfires as well as modern day fossil fuel use, according to a new study in Geophysical Research Letters.

One for all, all for one: A global river research network

Intermittent rivers are an increasing share of the world's river network, but current models don't include them. One research network is gathering knowledge about these rivers from around the world.

Research Spotlights

Curiosity Sends Curious Water Data from Mars The rover's neutron spectroscopy instrument hints at an unexpected trend: The upper soil levels in the layers of Gale Crater's Kimberley formation seem to hold more water-associated hydrogen, according to a new study in the Journal of Geophysical Research: Planets.

How regional wind patterns will influence climate change

Climate change is expected to cause wet regions to get wetter and dry regions to get drier, but a new study in Geophysical Research Letters suggests the truth is more complicated.

A new view of the plate dynamics behind earthquakes in Ecuador

Scientists get one step closer to an updated seismic hazard map that could help Ecuador prepare for future tremors, according to new research in Tectonics.
