New regulations issued by the Obama administration will force the country's coal- and oil-fired power plants to reduce the emission of pollutants such as arsenic and mercury or shut down.
In a statement, the Environmental Protection Agency said the new standards "will protect millions of families and children from harmful and costly air pollution and provide the American people with health benefits that far outweigh the costs of compliance."
Abuse in nursing homes and suspicious deaths among seniors often go undetected because postmortem examinations are becoming few and far between.
Earlier this year, an NPR News investigation found that many jurisdictions stopped doing autopsies on people who died over the age of 60, unless it was obvious that a violent death occurred. A lack of resources, both financial and staffing, was often to blame.

U.S. Sen. Scott Brown (R-Mass.) faces reporters at a hotel in Boston in August. Brown won the seat in a special election in 2010 in large part by contrasting himself with the Kennedy dynasty.
Republican Scott Brown of Massachusetts made a point of calling Ted Kennedy's old U.S. Senate seat the "people's seat," and he won it in large part by casting himself as the opposite of that glamorous and privileged dynasty.
Brown won in a special election in 2010. Now, Democrat Elizabeth Warren, a Harvard Law professor and Wall Street watchdog, is raising Democrats' hopes they can win the seat back. Just months after announcing her first-ever candidacy, polls show Warren pulling out ahead of Brown.
