Pacific Standard – Why Cleaning Up Abandoned Lots Can Reduce Shootings (featuring American Journal of Public Health study)
In his earlier days, Charles Branas studied whether aggression-management classes prevented violence. He found that sometimes such classes worked, sometimes they didn’t, and even when they did prove effective, cities often weren’t interested in providing the necessary funding.
Branas, an epidemiologist at the University of Pennsylvania, thought there must be a different way to reduce violence in cities — maybe some kind of environmental tweak that would affect a lot of people at once. So he ran a focus group in Philadelphia. Respondents came back to him with a surprising answer: Clean up the abandoned lots and buildings in the neighborhoods.

CNN – Common household chemicals hurt our health … and cost us billions
Routine contact with plastic bottles, toys, food cans, cosmetics and flame retardants containing “endocrine-disrupting chemicals” results in ingestion, leading to a toxic buildup and potentially a variety of medical conditions.
Routine exposure to these chemicals adds up to annual costs in excess of $340 billion — a whopping price tag that comes in the form of poor health, increased medical bills and lost income, according to researchers at NYU Langone Medical Center.

The Washington Post – Calcium supplements could increase risk of heart disease, new study finds
Calcium supplements that many women take to boost bone health increase their risk for heart disease, a new study has found.
The results show that calcium supplements make people more prone to plaque buildup in arteries, which contributes to the risk of a heart attack. The study, published in the Journal of the American Heart Association, is the latest salvo in a nearly decade-long debate about whether the supplements do more harm than good.
