Researchers at the Primate Research Center in Davis examined three-year-old rhesus monkeys that had been exposed as newborns to high levels of air pollution caused by wildfires burning around Northern California in 2008. The study shows that the monkeys, who were living outdoors at the time of the fires, were less able to fight off infectious diseases than animals born after the fires.
Lung development in rhesus monkeys and humans is very similar. The study is the first to show that particulate matter has a direct impact on primate immune system function.
The research suggests that exposure to particulates early in life could result in decreased lung capacity and lowered immunity persisting into adulthood.
The drought intensified over the last week in the Western U.S. as the region swelters under a heatwave and firefighters battle major wildfires.
A new poll shows Californians support the goals of the state’s landmark law to reduce greenhouse gas emissions. It also found that Californians want state and local governments to do more when it comes to the drought.
Mandatory statewide water conservation rules have ended in California. But Sacramento-area users conserved 22 percent in June, compared to June 2013.
A UC Davis researcher has used pigeons to track lead pollution in New York City and plans to do the same in California cities and agricultural areas.
The state of Nevada will pay $120,000 to settle a U.S. Environmental Protection Agency complaint about storm water runoff pollution in Reno.
