After scoring a Supreme Court victory this spring, the Environmental Protection Agency can move forward with its strategy to cut air pollution from coal-fired power plants in several states — and new research suggests the impact could be lifesaving.
Scientists assessed the effects of one state's prescient restrictions on plant emissions in a report in the ACS journal Environmental Science & Technology. They estimated that the state's legislation prevented about 1,700 premature deaths in 2012.
Jacqueline MacDonald Gibson and Ya-Ru Li explain that the U.S. has been working for years to lower levels of particulate matter, a form of air pollution that can cause serious health problems when people breathe it in. Certain kinds of particulate matter form mainly from power plant emissions.
More than 10 years ago, correctly anticipating the federal government would eventually set tighter restrictions on power plants, North Carolina had approved more stringent goals than neighboring states. It required 14 major coal-fired plants within its borders to reduce emissions of nitrogen oxides and sulfur dioxides by 60 percent and 72 percent, respectively, over a 10-year period. Gibson's team wanted to see what effect the measures were having.
They found that the policy had successfully reduced emissions in North Carolina more than other southeastern states. Sulfur dioxide levels, for example, dropped an average of 20 percent a year from 2002 to 2012. Across all southeastern states, they dropped 13.6 percent per year. As a result of the improved air in North Carolina, the scientists used a health impact model to estimate that about 1,700 lives were saved in 2012 alone.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
