A White House deal with Eli Lilly & Co. and Novo Nordisk to lower the prices of their popular obesity medicines, Zepbound and Wegovy, is a step toward making them more affordable and accessible to Americans — but until we have more details, it’s hard to tell how big a step it really is.

Six Americans have died and more than 20 others have been sickened in a growing listeria outbreak linked to prepackaged pasta meals. It is upsetting, but not surprising. I worked on food safety at the Food and Drug Administration for many years. The U.S. has one of the safest food systems in the world, but too many Americans fall ill from contaminated food every year — and too many families experience tragic, preventable loss. That’s unacceptable in the 21st century. (Frank Yiannas, 11/7)

Former vice president Dick Cheney’s death stunned me this week — because of how extraordinarily long he lived in defiance of a failing heart.
