Sgt. Candice Puente, a drill instructor for Platoon 4011, Oscar Company, 4th Recruit Training Battalion, looks over her recruits’ marksmanship data book on the rifle range Feb. 25, 2014, on Parris Island, S.C. Recruits use marksmanship data books to keep track of their progress and to adjust their techniques accordingly. Rifle qualification is one of eight requirements recruits must fulfill to become Marines. Puente is a 26-year-old native of El Paso, Texas. Oscar Company is scheduled to graduate April 4, 2014. Parris Island has been the site of Marine Corps recruit training since Nov. 1, 1915. Today, approximately 20,000 recruits come to Parris Island annually for the chance to become United States Marines by enduring 13 weeks of rigorous, transformative training. Parris Island is home to entry-level enlisted training for 50 percent of males and 100 percent of females in the Marine Corps. (Photo by Lance Cpl. Vaniah Temple)

Americans Breathing Easier With Fewer Particulates In The Air
by Michael Keller
We may not have noticed it, but Americans are breathing a little easier thanks to a great story for the country’s air quality.
A Rice University study concludes that states are successfully reducing a harmful air pollutant called fine particulate matter less than 2.5 micrometers (PM2.5) in diameter, which can stay suspended in the atmosphere for weeks and has been linked to chronic and fatal diseases.
In fact, the study found that state efforts have been so successful that most urban areas had already lowered PM2.5 to more stringent levels instituted in 2012 by the U.S. Environmental Protection Agency. The improvements are good enough to translate into Americans living slightly longer lives.
“The trend across the country is that air quality is improving,” says Daniel Cohan, an atmospheric researcher and associate professor of environmental engineering. “Power plants are getting better at controlling emissions. There are more industrial controls to pollution. Cars are getting cleaner.”
