This kind of corruption is as brazen as it gets. Trump is easily the most corrupt President in our country's history. Yet Republicans in Congress are not lifting a single finger to exercise basic oversight. Shameless complicity.

The EPA employees were fired on a Labor Day weekend that also marked a historic assault on labor. Half a million federal employees have lost union protections under Trump, with more to come. This includes EPA employees. Trump says this is for "national security" reasons, and courts have gone along.

Unions might be imperfect, but they are the best organized representative of government employee interests at the time when Trump have been purging the government, including removing internal safeguards that would typically adjudicate on claims of unfair treatment of employees. While unions are often portrayed as self-interested, lets look at the EPA. The American Federation of Government Employees renegotiated their union contract with EPA in 2024. With the potential for the Trump administration in mind, they union focused on protecting the scientific integrity of their member’s work. This is something that professional scientists care about, and which benefits the public. In other words, it is a domain where the public interest and union goals overlap.

A federal court is allowing the EPA administrator to cancel a $20 billion program, created in law via the IRA, to distribute climate change grants. The court says these are contracts not grants, and so only the Court of Federal Claims can review. Unconstitutional violations via technicality!

The DC Circuit said that the affected firms that lost the grants can ask for compensation for their losses (for which EPA and taxpayers will potentially be liable). But this misses the point. The courts are allowing the administration to cancel prior policies involving obligated funds. That is the broader harm: the Trump administration negated the distribution of past funds as ordered by Congress, effectively cancelling a lawful climate change program without going through Congress to do so. The decision is part of an ongoing pattern of the Trump administration claiming Congressional powers, and of Trump appointees in the judiciary enabling this power grab. In dissent, Judge Pillard said: the majority allows the government to seize Plaintiffs’ money based on spurious and pretextual allegations and to permanently gut implementation of major congressional legislation designed to improve the infrastructure, health, and economic security of communities throughout the country.

I will be diplomatic and say that I think a lot of studies expose current organisms to predicted extreme future conditions, and some of them are more applicable than others.

My book 'Charles Darwin's Barnacle and David Bowie's Spider' is now just $10 at the evil corporate giant. At that price, I can't imagine why you wouldn't read it (and buy an extra copy for your sister). $10! I'm almost insulted :-) https://amzn.to/425pMbR

Can someone please make a 10-second looping video of UNC fans leaving the game early as they're getting blown out by TCU? I want to make it my Zoom virtual background.

(and also also, I mean "talk about their own stuff" broadly to include sharing other work in their field and also people's own hobbies, lives, where they live etc. -- basically anything that's specific to someone's own individual perspective)

Someone asked me why sharks stick their dorsal fins out of the water. The answer is simple. Sharks’ dorsal fins stick out of the water sometimes because their fins are on top of and therefore higher than the rest of their body, and sometimes their body is near the surface of the water.

I see a lot of DC media dunking on Trump’s 2 pm appearance today, with some version of, “Obviously he’s not dead, you online libtards!” But Trump appearing in public doesn’t lessen or answer the very real and obvious questions about his health. This is a subject that requires real digging.

I see a lot of people who I know do fascinating work that I'd love to hear more about, but whose feed ends up being mostly reposts of the same three pieces of news everyone else in my feed is posting (again: people should post what they want! this is just something I feel personally!)

since we're apparently having a meta conversation about This Site (I was mostly away for a week and DO NOT want to know what I missed), I will say that, although this is absolutely not a demand for people to Post Differently, I do wish subject matter experts would talk more about their own stuff

“The DOE report is basically arguing climate change is no big deal, therefore we shouldn't act. Always it's about trying to delay action and maintain the status quo."

Florida banned shark feeding by SCUBA divers in state waters in fall 2001. And one SCUBA business owner phrased this as "Americans' freedom was attacked TWICE this September."
