Areas of the Arctic play a larger role than previously thought in the global nitrogen cycle—the process responsible for keeping a critical element necessary for life flowing between the atmosphere, the land and oceans....
A map of the Himalayan arc. The country of Bhutan is abbreviated BTN. A new study shows Bhutan has experienced a major earthquake in the past 500 years, meaning the entire Himalayan arc is capable of producing large earthquakes.

Stanford researchers discovered that in agricultural areas of Costa Rica, increased tree cover corresponds with increases in biodiversity. (Image credit: David Spangenburg)
Scientists used tree cover maps and on-the-ground observations to measure biodiversity in Costa Rica. The results generated a...
Scanning the pristine skies above the Amazon rainforest revealed that small aerosol particles that form naturally in the upper atmosphere are carried to the lower atmosphere by rapid downdrafts associated with rainfall. There, volatile organic compounds (VOCs) emitted by...

The prevailing notion that the African continent has been getting progressively drier over time is being challenged by a new study that finds that drought has actually decreased over the past 1.3 million years...

Oceans might not be thought of as magnetic, but they...
Sea level change resulting from Greenland ice melt, derived from NASA GRACE measurements. Black circles show locations of the best historical water level records, which underestimate global average sea level rise due to Greenland melt by about 25 percent.Credits:...

A new global assessment of forests -- perhaps the largest terrestrial repositories of biodiversity -- suggests that, on average, a 10% loss in biodiversity leads to a 2 to 3% loss in the productivity, including biomass, that...
New research shows that landowners in Brazil are clearing more forest than government measures suggest. In the satellite image above, black boxes and yellow dots indicate deforestation taking place in the blind spots of Brazil's forest monitoring system.Credit: VanWey...
