An Army Corps project could wipe out one of Florida’s last thriving coral reefs The fate of one of the last thriving coral reefs in Florida may be imperiled by plans to widen the shipping channel leading into Port Everglades.

The US army corps of engineers is considering, right now, what would be the largest destruction of coral reefs in US history. To make a port slightly bigger.

People know this, right?

Renee Good's partner addresses Minneapolis immigration crackdown one month after killing Becca Good has seldom spoken out since Renee Good was shot and killed by an ICE agent in Minneapolis on Jan. 7.

β€œRenee was not the first person killed, and she was not the last,” Becca Good said. β€œYou know my wife’s name and you know Alex’s name, but there are many others in this city being harmed that you don’t know β€” their families are hurting just like mine, even if they don’t look like mine.”

Really hard to look at this and all the other examples of bravery and kindness from ordinary people in this moment not think also of the tremendous cowardice exhibited over the past year by some of the richest, most well-protected people in business, media and politics

During a military-style raid on a building in Chicago’s South Shore, one resident heard a knock on his door. 

It wasn’t the feds β€”Β  it was a mom and her 7-year-old daughter, pleading for help.

He let them hide in his unit for the next 3 days.

I've said this before, but I feel pretty strongly that the building of concentration camps - and now, the inevitable disappearance of 1,800 people from those camps - is the biggest story in American public health right now that isn't being treated like one

 A photograph of the front page of The New York Times dated September 2, 2025. The main headline reads: β€œIn Blitz on Science, Experts Warn of an Autocratic Tilt.” Below it are two featured articles. The first, by Apoorva Mandavilli, is titled β€œC.D.C. Left Battling for Its Survival” and describes turmoil at the Centers for Disease Control and Prevention since Robert F. Kennedy Jr. became health secretary, leading to staff losses, leadership resignations, and questions about the agency’s legitimacy. The second article, by William J. Broad, is titled β€œAre Research Cuts Fighting Red Tape or Free Inquiry?” and discusses threats to science and research under political pressure.

A1 above the fold in the @nytimes.com. The message is getting through. Keep pushing everyone. We can save the #CDC, save the #NIH from the clutches of #RussellVought #StephenMiller and #DonaldTrump. Keep the pressure up on your members of Congress and the media (letters to editors, op-eds).

All academic institutions will soon realize we are in this together, facing an autocratic ruler who wants to destroy academia, science, and public health (together with media and courts - pick up a history book).

There is only one solution - stand up, speak up, and, critically, collective action.

Tuberculosis rates plunge when families living in poverty get a monthly cash payout A program in Brazil that gives a monthly cash sum to families living in poverty has an unexpected β€” and welcome result. A new study shows that it is dramatically reducing tuberculosis rates.

"The study is impressive in its scale...cases and deaths dropped by more than 50% and in the Indigenous population the drop was even more dramatic: more than 60%."

Nature Medicine study shows the effects of Bolsa Familia strongest in Black and Indigenous populations
