This fucking guy has immersed himself in a world where everything he does is to further his ideology, and ended up in a fever dream where he has lost the ability to contemplate things that aren't ideological.

This year, India will beat the US on renewables deployment. Its goal to reach 500 GW in carbon-free power capacity by 2030 now looks achievable. www.bloomberg.com/opinion/arti...

Some sweet people have been sending physical cards and letters to the Bethesda Declaration signers. This is so kind and meaningful.

It would be GREAT if they received more. Cards can be sent to

Ian Morgan
NIGMS
45 Center Dr, MSC 6200
Bethesda, MD 20892-6200

Ian will share them with the signers.

For the record, we’re at NIH, EPA, NASA, NSF now all with public statements against leadership. EPA has retaliated, placing hundreds on leave pending a bullshit investigation.

People working at scientific agencies signed up for one thing and are being told to do the opposite. They don’t like it.

Just to be clear, since there may be a couple of misunderstandings: It's the shark from Jaws photoshopped in.

And the shark tagging feature has now published, a few days earlier than I thought it might. Come join me as I pretend to be that other kind of biologist for a day.

For this sort of press-based propaganda, corrections seem like responsible journalism, but it's too late. The impression has already been made, the corrections are seen by a fraction of the readers who saw the original headline, etc.

And the people at these outlets know that.

It's not just the visuals, which are spectacular - the narration of every one of this long list of photos is compelling too.

Eric Berger would have had to pull some strings for that to be an option.

Image of a person in an orange shirt, sunglasses, and tanned hat, holding a spool of line with a hook at the end, with a fish head as bait. Behind him is an expanse of blue-green water. Someone has photoshopped in the shark from jaws erupting from that water.

I told Ars' creative director, @aurich.bsky.social, that I had a feature coming up about going shark tagging with @whysharksmatter.bsky.social, so he asked for some photos to find one to use for the story's header image.

He sent me this one back.

One of our β€œgreen new scam” research grants that USDOT terminated focused on making transit infrastructure more resilient to more frequent and severe weather events. But β€œclimate change adaptation” was too woke, obviously, and doing this research is clearly unnecessary

There's a lot of bad stuff going on the world that I have little to no control over. But I have complete control over whether I have a clean bike chain, so excuse me while I spend a few moments enjoying that.

They are, to borrow Gorsuch's phrasing, writing "rules for the ages", but probably not in the way they think.

DOGE told regulator to β€˜rubber stamp’ nuclear The Nuclear Regulatory Commission's historic role of assuring safety is changing as the White House shifts some responsibility to the Department of Energy.

In amidst everything else, the Trump Administration is trying to redo the entire pathway for regulating nuclear power.

I'm assuming the "GW" is a stand in for "global warming", given the ludicrous energy use if these things could exist.

If you were wondering about the lack of opposition to massive research cuts from the investor class, and you think "surely they can't be so stupid that they fail to realize that most startups that get launched arise from government-funded, fundamental research", well, maybe it's time to think again.

America’s Brain Drain Could Become the World’s Brain Gain Research-funding cuts and immigration changes threaten some of America’s economic advantages.

Since WWII, America has led the world -- economically and in so many other ways -- in no small part because of its willingness to spend on basic research and its ability to attract the world's best and brightest.

That is changing -- fast. My deep dive on the topic:
