Bidi more harmful than cigarette: Study
In probably the first such large-scale study of its kind, Sekhsaria Institute of Public Health, in collaboration with the ministry of health proved that bidis and other forms of tobacco (supari, gutkha, among others) are more harmful than cigarettes. The study had a follow-up period of 5.5 years with as many as 87, 222 male members from Mumbai participating in it.

National ambient air quality standards for carbon monoxide
Based on its review of the air quality criteria and the national ambient air quality standards (NAAQS) for carbon monoxide (CO), EPA is proposing to retain the current standards. EPA is also proposing changes to the ambient air monitoring requirements for CO including those related to network design.

The burning issue
<p>Fortunately for us, carbon monoxide (CO)—a toxic gas—is a very minor constituent of the atmosphere. It is produced by incomplete burning of fossil fuels and biomass (such as dry leaves and wood) and by the oxidation of methane and other volatile hydrocarbons in the atmosphere. </p>

Large variations in Southern Hemisphere biomass burning during the last 650 years
<p>We present a 650-year Antarctic ice core record of concentration and isotopic ratios (δ<sup>13</sup>C and δ<sup>18</sup>O) of atmospheric carbon monoxide. Concentrations decreased by ~25% (14 parts per billion by volume) from the mid-1300s to the 1600s then recovered completely by the late 1800s.

Structural basis of biological N2O generation by bacterial nitric oxide reductase
<p>Nitric oxide reductase (NOR) is an iron-containing enzyme that catalyzes the reduction of nitric oxide (NO) to generate a major greenhouse gas, nitrous oxide (N<sub>2</sub>O). Here, we report the crystal structure of NOR from <em>Pseudomonas aeruginosa</em> at 2.7 angstrom resolution. The structure reveals details of the catalytic binuclear center.
