Decades ago, Kris Hansen showed 3M that its PFAS chemicals were in people’s bodies. Her bosses halted her work.
As the EPA now forces the removal of the chemicals from drinking water, she wrestles with the secrets that 3M kept from her and the world.

It turns out that the major pharmacies in the U.S. routinely provide patient medical records to law enforcement without a warrant. The potential ramifications of this for anyone on birth control, ordering abortion pills, or medication for mental illness and other personal conditions are staggering.

Should really be age-adjusted. 25-34 is a huge range (it's much of the fertility window) and we know that a higher % of Millennial women give birth at the high end than past gens. So is it an age--or some other--effect? Along w/changing reporting standards, can we appropriately draw any conclusions?
This is unbelievable. The maternal mortality rate for millennials in the US aged 25 to 34 is 230% higher than it was for Gen Xers and 300% higher than it was for baby boomers of the same age
