"Scientists strive to be apolitical, but they can’t keep politics out of their labs" | Great review of my new book with @peterhotezmdphd.bsky.social, #ScienceUnderSiege, in the @latimes.com (and @yahoonews.com), courtesy of Michael Hiltzik: www.yahoo.com/news/article...

Hiltzik: Scientists strive to be apolitical, but they can't keep politics out of their labs

Since Galileo's time, politicians and ideologues have always tried to interfere with science. It's worse than ever today.

The right's bad faith attack on our media infrastructure and our democracy is bleeding across borders and oceans:

Instead of some proportion from much of the British media class, we are treated to the tragicomic absurdity of a former British prime minister willing to admonish the national broadcaster and demand the resignation of its Director General, all in the name of defending Donald Trump’s reputation for truth-telling. But it’s worse than that- it is a textbook example of how populists win. We have the ridiculous carnival of Donald Trump and Boris Johnson, of all people, admonishing the BBC for its lack of integrity. And they can get away with it, because no-one expects anything from them and yet we expect everything from the people and places who actually give a damn.

The Dems who didn’t stick together are the 8 (including King, technically an independent) who joined with Republicans to block ACA benefits.

The reaction to the Panorama edit has been nothing short of hysterical. Yes the BBC has some impartiality problems. But its biggest isn't the one you think.

New piece from me.

people will die because of this. That's pretty catastrophic--for them and their loved ones.

but now those WON'T be "owned by the Republicans". The Republicans can credibly claim there was "bi-partisan" support, and our compromised media will parrot their talking points.

Michael E. Mann @michaelemann.bsky.social · 21h

Don't be done with the party. In a two party system where one party is trying to destroy the planet, there is no other choice. But DEMAND NEW LEADERSHIP.

Michael E. Mann @michaelemann.bsky.social · 21h

are you kidding me! He's minority leader. He whipped his caucus on this, knew exactly how many votes were needed, and what result he wanted. He then insulted us by using his own nominal "no" vote as a shield. Pathetic!

Don't give another dollar to Democrats until @schumer.senate.gov resigns as Minority Leader
