What do these places have in common: Camp Lejeune in North Carolina; Mountain View, California, where Google headquarters are located; Endicott, NY – the birthplace of IBM; and 389 Superfund sites in at least 48 states plus Puerto Rico and the Virgin Islands? All are contaminated by trichloroethylene (TCE), a carcinogenic solvent. TCE’s health hazards are well-documented. So why are Republicans rushing to condemn EPA’s just-completed TCE risk assessment?

Last year, the U.S. Census reported that record numbers of people were living in poverty. But along with overall poverty numbers, the Census recently reported that concentrated poverty is up, too — and that’s worrisome because it means that more people may face even greater barriers and fewer opportunities to moving out of poverty.

Vaccine safety is one of those topics that has become so tragically mired in misinformation and myth that there can never be enough supporting evidence. So, here’s some more.

Ideally, everyone should be tested for HIV. In reality, however, only about half of U.S. adults have ever been tested for HIV and about half of the 50,000 new infections that happen every year in the U.S. are transmitted by people who are unaware of their HIV status. Such statistics recently led a group of researchers to ask if there’s a more efficient way to go about curbing the HIV epidemic.

When a widely used chemical is identified as an environmental health hazard and targeted for phase-out and elimination, among the most challenging questions for those involved with making such a chemical are: What to use instead? and Will the replacement be safe? The US Environmental Protection Agency’s report identifying alternatives to the flame retardant hexabromocyclododecane (HBCD) illustrates how difficult those questions can be to answer.

Childhood lead poisoning is one of those health risks that everyone has likely heard about, but many probably think it’s a problem of the past. However, a recent study reminds us that in just one state — Michigan — the effects of childhood lead poisoning cost about $330 million every year. And that’s a conservative estimate.

Five million dollars. That’s how much the fast food industry spends every day to peddle largely unhealthy foods to children. And because studies have found that exposure to food marketing does indeed make kids want to eat more, advertising is often tapped as an obvious way to address child obesity. Fortunately, a new study finds that the public agrees.

Researcher Christopher Wildeman has spent his whole career describing and quantifying the more unpleasant parts of people’s lives and his latest study on the surprising prevalence of childhood maltreatment is no exception. Still, there is a bit of a silver lining.

The heath effects of occupational solvent exposure don’t always fade with time. A new study has found that years — sometimes even decades — down the road from their last workplace exposure, some workers are still experiencing very real cognitive impairments.

Late last year as many Americans purchased affordable health insurance for the first time, others opened their mailboxes to find notification that their coverage had been cancelled. The story erupted across media channels, as President Obama had promised that people could keep their plans, but the overall issue was presented with little perspective. Thankfully, a new study offers something that’s become seemingly rare these days: context.
