What I Saw at a Maternity Ward in Kenya After the U.S. Cut Off Food and Foreign Aid
Photographs tell a story of two mothers determined to help their babies gain enough weight to leave the hospital — only to face little to no food again.

Health authorities are encouraging everyone aged 6mo+ to get the flu vax (it's not too late).

Every mass shooting is a horrific, preventable loss and a reminder that we have traded the rights of the many for the rights of a few. University or school shootings are especially gutting, not just because of their nearness (I’m a professor) but because it feels like such a violation of the sacred.

Today is the anniversary of the Sandy Hook shooting. There are no words to express the grief and anger that our young people continue to be slaughtered in school.
And for what? More guns?
This is a policy failure — and a moral one. Enough.
