California's dirty air caused more than $193 million in hospital-based medical care from 2005 to 2007 as people sought help for problems such as asthma and pneumonia that are triggered by elevated pollution levels, according to a new RAND Corporation study. Researchers estimate that exposure to excessive levels of ozone and particulate pollution caused nearly 30,000 emergency room visits and hospital admissions over the study period. Public insurance programs were responsible for most of the...

Johns Hopkins University researchers have created biodegradable nanosized particles that can easily slip through the body's sticky and viscous mucus secretions to deliver a sustained-release medication cargo. The researchers say these nanoparticles, which degrade over time into harmless components, could one day carry life-saving drugs to patients suffering from dozens of health conditions, including diseases of the eye, lung, gut or female reproductive tract. The mucus-penetrating...
