Microplastics are everywhere, study finds

Microplastics are everywhere—including in our drinking water, table salt and in the air that we breathe. Having studied the scope of microplastics in a number of countries, researchers are worried.

Water heaters' methane leaks are high, but fixable

Natural gas escapes from water heating systems through leaks and because some is not combusted by the burner. These tiny inefficiencies can add up: The resulting emissions of methane—a powerful greenhouse gas—for water ...

Researchers quantify ecosystem-scale nitrification rate

Human-caused increases in gaseous nitrogen (N) emissions to the atmosphere have accelerated terrestrial ecosystem N deposition over the past half-century. As forest productivity is usually N limited, accelerated N deposition ...
