Laser sniffs out toxic gases from afar
Scientists have developed a way to sniff out tiny amounts of toxic gases—a whiff of nerve gas, for example, or a hint of a chemical spill—from up to one kilometer away.
Another human footprint: Rising anthropogenic nitrate levels in the North Pacific Ocean
Human-induced changes to Earth's carbon cycle - for example, rising atmospheric carbon dioxide and ocean acidification - have been observed for decades. However, a study published this week in Science showed ...

Increase in CO2 has not stimulated growth of tropical trees
Since the start of the industrial revolution in 1850, atmospheric CO2 levels have increased by about 40%. However, contrary to expectations, the growth of tropical trees has not increased as a result. Th ...
Cooled-down plasma could help detect elusive nanoparticles responsible for so many health hazards
We're awash in tiny nanoparticles. Some are components of car and truck exhaust; others are manufactured intentionally for products ranging from cosmetics to electronic devices. Most are only a few nanometers ...
Looking at El Niño's past to predict its future
The El Niño Southern Oscillation is Earth's main source of year-to-year climate variability, but its response to global warming remains highly uncertain.
Land use looms as large factor in global warming
For the world's deteriorating environment, don't blame burning fossil fuels exclusively. Land use and land cover changes contribute about 40 percent to "radiative forcing," a key underlying factor in global warming, according ...
