New insights into plant uptake of carbonyl sulfide aid global carbon cycle model
In a study published in Science on 14 November, NOAA and CIRES scientists and colleagues show that carbonyl sulfide (COS), a trace gas consumed by plants, provides quantitative evidence that gradients of COS during the growing season are controlled by plant uptake during photosynthesis. This in turn provides an independent measure of plant photosynthesis rates crucial for carbon cycle modeling, a ...

Heavy Metals Found Along U.S. Roadways Linked To Brake Pads
A recent environmental impact study revealed that the majority of pollutants found near U.S. roadways did not come from tailpipes, but instead from brake pads and tires. Water and air samples were collected by scientists in the study and they found bits of the brake pads which contained mercury, lead and cadmium. These heavy metals can cause cancer and birth defects. In 2010, The Better Brake ...

Methane data are rolling in from the Russian Arctic, after bug battles and an overturned research lab
In a remote part of the Russian Arctic, a land studded with thousands of lakes and a few towns, a thin electric cable connects a tiny research station and instrument tower with a power generator more than a mile away. The cable—made for indoor use—travels outdoors along juryrigged tripods made of branches. Moose will knock down anything, eventually, and the tripods are cheaper and easier to ...
