Leaking natural gas wells are considered a potential source of methane emissions, and a new nanomaterial cement mixture could provide an effective, affordable solution for sealing these wells, according to a team of Penn State scientists.

A University of Oklahoma-led interdisciplinary study on a decade-long experiment (1997-2009) at the University of Minnesota found that lower nitrogen levels in soil promoted release of carbon dioxide from soils under high levels of atmospheric carbon dioxide, and could therefore contribute to furthering rising atmospheric greenhouse gases and climate change.

As Covid-19 infections soar across the U.S., some states are tightening restrictions and reinstituting quarantine measures to slow the virus’ spread.

The Norwegian research organisation SINTEF will investigate whether rare earth element minerals contribute to pollution in costal areas.

For the first time scientists have provided clear evidence that tropical tree lifespan decreases above a critical temperature threshold.

Clear skies over the Rocky Mountains helped a temperature inversion to form, which in turn led to cloud-filled valleys.

Nitrogen dioxide (NO2), an air pollutant, decreased significantly over urban areas during the pandemic.

This may be the first time data collected using uncrewed surface vehicles were used to help produce an annual estimate of abundance for a commercial fish stock.

Using a bacterial strain found in mangroves, Texas A&M researchers have uncovered a low-cost, sustainable method for producing bioplastics from sewage sludge and wastewater.
