First the researchers split both the Swedish and American babies into two groups....

“We do think that the social environment, it has the potential to be the most chronic form [of stress],” says Fernando Campos, lead study author and Assistant Professor of Biological Anthropology at The University of Texas at San Antonio. “You’re sitting low in the hierarchy, you’re always being displaced from food, you’re always being picked on, or always having to look out for others that might feel aggression toward you—this has real potential to be a source of chronic stress....

The Food and Drug Administration and Abbott Nutrition reached an agreement on Monday for the company to take corrective measures and reopen its facility in Sturgis, Michigan, in an effort to mitigate the current shortage. The FDA announced that this move should get more infant formula products back on the shelves—the agency will be keeping a close eye on Abbott Nutrition to ensure that the manufacturer meets safety standards. On Monday, the FDA separately announced more flexible guidelines for international companies importing baby formula products to the US as a way to boost availability....
