Huffington Post—Obama Administration Releases Final Ozone Rule, Pleasing No One
The Environmental Protection Agency released a contentious and long-awaited new limit on ozone pollution Thursday, and it’s not likely to mark the end of the argument. The EPA’s final rule for ground-level ozone pollution, better known as smog, sets the standard at 70 parts per billion, lowered from the current standard of 75. Environmental and public health groups had been anticipating this figure for some time, though it is at the high end of what they wanted. American Public Health Association’s executive director, Dr. Georges Benjamin, said that a 60-parts-per-billion standard would have been “the most protective of public health, based on the latest science,” but that lowering the limit to 70 “is a significant step in the right direction.”

CNN—Not mom’s weight loss: For millennials, more than diet and exercise at play
It’s a never-ending battle: You diet and exercise, but can’t shed the pounds. You can at least take comfort in a new study that suggests many other factors, including stress and pollution, could be conspiring to make weight loss harder today than a few decades ago. Researchers looked over the years at what adults in the United States said they ate, how much they reported exercising and their body mass index (BMI). The data came from the National Health and Nutritional Examination Survey and  included dietary information from nearly 36,400 people between 1971 and 2008, and physical activity information for about 14,400 people between 1988 and 2006. The study concluded that a person in 2006 who consumed the same number of calories and exercised the same amount as someone in 1988 would have a BMI that was 2.3 points higher.

The New York Times—US Proposes Provision on Tobacco in Trade Pact
The United States proposed this week to bar tobacco companies from using special trade tribunals to sue or threaten countries that passed antismoking laws, hoping to remove one roadblock to what would be the largest regional trade agreement in history. The tobacco provision remains tentative, but its inclusion in the 12-nation Trans-Pacific Partnership being negotiated here would be a major victory for public health advocates and could set a precedent for other trade pacts. Tobacco companies have been using existing global trade agreements to counter antismoking laws, especially in poorer nations, and advocates fear that the Pacific trade accord could provide another legal weapon. Public health experts said the tobacco industry’s use of so-called Investor-State Dispute Settlement tribunals had become so widespread that many poorer countries were abandoning their antismoking efforts. Those underdeveloped nations are also the newest markets for tobacco companies, which are struggling to offset big declines in smoking in the United States and other rich countries.
