In 2002, the Odyssey probe discovered evidence of past ice on Mars. The U.S. Congress authorized the Iraq War resolution. The Anaheim Angels won the World Series. And in a meadow 15 miles north of Flagstaff, scientists began to monitor and move small plots of soil...
By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial...
Antibiotic-resistant bacteria are widespread and are increasingly associated with human infections. Inappropriate antibiotic use – both in people and in animals raised for food – drives the evolution of multi-drug-resistant pathogens and threatens a post-antibiotic...
Permafrost, the “always-frozen” deep soil layers of the Arctic, naturally undergoes freeze-thaw cycles with the passage of the brief Arctic spring and summer, which thaws the uppermost layers and fosters a burst of tundra plant growth and pooling meltwater from...
Biochar, a fine-grained carbon residue of charred plant material, has recently been promoted as a universal amendment to soil to improve moisture and nutrient content with the expectation of higher agricultural yields, fostering the rise of a large global biochar...
Ecoss research demonstrated that grasslands with more diverse plant species pull down and store more carbon per acre: in this illustration, the same plot of soil from a diverse vs. depauperate grassland shows more belowground investment in deeper roots and denser...
