"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.

"Can the World Address Climate Change Without the US?" by Jackie Flynn Mogensen & Henry Carnell for @motherjones.com:

Can the world address climate change without the US?
Even with Trump's America absent, COP30 ended in a weak deal—and a win for petrostates.

Substack has a Nazi problem AND a health disinformation problem
Substack creators and Substack audiences are supporting a platform that profits off of promoting dangerous antiscience content – at the expense of public health.

🚨 NEW/EXCLUSIVE: The FBI turned over dozens of emails to me in response to my #FOIA request that provides a behind-the-scenes look at discussions involving the review and redaction of the Epstein files

www.bloomberg.com/news/newslet...
Email says We are prepared to receive boxes tomorrow, as NY agents are travelling to WFO in the morning, and vill arrive to Winchester where they will start photographing and we will start scanning and processing the physical files. Once I see the volume, I'|l have a better estimate of processing times, although 1 suggest we do a rolling delivery to further demonstrate the FBIls commitment to delivery and transparency.

Swapping + and - in an equation, failing to correctly compensate for the changing value of GDP over time. If I had ever made a mistake like that in my scientific career, I would have retreated to a cave in the mountains to live out my days as a hermit.
