Why AI Is 'Not Particularly Good' at Curing Disease (Plus: The Next GLP-1 Boom and Why America Hates Big Pharma) A wide-ranging interview with Dave Ricks, the CEO of Eli Lilly, which makes the GLP-1 drugs Mounjaro and Zepbound and recently became the first trillion-dollar pharma company in history

Striking @dkthomp.bsky.social interview w/ Eli Lilly CEO Dave Ricks covering the widespread effects of GLP-1 drugs, AI as a bad cancer-cure finder, why people hate Big Pharma, and more.

Gotta say, I often wonder if these drugs will end up having way more long-term impact on our lives than AI.

The counterargument would be that a lot of both Defoe and Twain are brilliantly written but slapdash. I just read "Roughing It." It was hilarious and amazing--but it also would've benefited from Twain going over the first draft and asking himself hard questions about its structure.

State of the Species - Orion Magazine Does success spell doom for Homo sapiens?

I re-read this essay by @charlescmann.bsky.social in February and July every year. It holds. Waiting to see if homo sapiens can turn the biological corner away from self extinction. So far, not looking good.

Tweet from Michael Tracy shows Epstein in a glamourous black overcoat with a fur neck above a crisp white short, open at the beck and wrists, in the parquet-floor foyer of some urban apartment. Behind him is an open door that frames a chandelier.

Excerpt from speech: "I used to have students who bragged to me about how fast they wrote their papers. I would tell them that the great German novelist Thomas Mann said that a writer is someone for whom writing is more difficult than it is for other people. The best writers write much more slowly than everyone else, and the better they are, the slower they write. James Joyce wrote Ulysses, the greatest novel of the 20th century, at the rate of about a hundred words a dayβ€”half the length of the selection I read you earlier from Heart of Darknessβ€”for seven years. T. S. Eliot, one of the greatest poets our country has ever produced, wrote about 150 pages of poetry over the course of his entire 25-year career. That’s half a page a month. So it is with any other form of thought. You do your best thinking by slowing down and concentrating."

DOJ Removed Record of Multiple FBI Interviews with Underage Trump Accuser, Epstein Data Shows The FBI spoke at least four times with a woman who credibly accused Trump of sexually assaulting her when she was a minor, Epstein files show. That document is no longer accessible on the DOJ website.

You can get annoyed at them, though, for waiting until the 16th paragraph to to note that NPR and Roger Sollenberger broke the story.

The NYT took 18 hours from the NPR report to confirm and (a bit) extend the story. I don't see that as bad. I see that as them attempting to be responsible.

Whoops--Means was nominated last summer. What the Trump people did this week was launch a campaign to push her through the Senate confirmation process, which has been stalled because Means espouses views that are vigorously resisted by a lot of US farmers.

Surgeon General Pick Deepens Rift Between Trump Admin and Farmers RFK ally expected to sail through upcoming Senate vote

As these guys point out, the Trump people's food/ag policy is totally incoherent. In a single week, they've promoted glyphosate production, proposed removing pesticides from environmental review in the Farm Bill--and nominated anti-GMO/anti-pesticide activist Casey Means to be Surgeon General.

I'd forgotten until I read the article that Trump tried the same rollback on mercury in his first administration. Guess who was the most prominent public opponent to the move? The guy who testified at public hearings to the harm it would cause?

RFK Jr., once poisoned by mercury, is silent as EPA weakens rules against it The HHS secretary has fought mercury pollution for years. He’s now in an administration that wants to make it easier for industries to dump it into the air

RFK Jr spent years denouncing mercury pollution from power plants. He was one of Trump's most public opponents when he tried to roll back mercury limits in 2017. He himself actually got mercury poisoning (eating too much fish). On Friday, Trump's EPA weakened mercury rules. RFK Jr said nothing.

Twitter post by Robert F Kennedy Jr on June 14, 2024, as he is running for president. It says: "The herbicide Glyphosate is one of the likely culprits in America’s chronic disease epidemic. Much more widely used here than in Europe. Shockingly, much of our exposure comes from its use as a desiccant on wheat, not as an herbicide. From there it goes straight into our bodies. My USDA will ban that practice."

COVID-19 vaccination status during pregnancy and preeclampsia risk: the pandemic-era cohort of the INTERCOVID consortium COVID-19 vaccination with a booster reduces the odds of PE by 30% approaching 60% reduction among women with pre-existing morbidities.

Remember when RFK Jr. unilaterally decided that COVID19 vaccines should no longer be recommended during pregnancy?

Well, COVID19 increases the risk of preeclampsia.

And it turns out that getting boosted, either before or during pregnancy, significantly reduces the risk of preeclampsia.

You'd expect him to keep silent or issue a noncommittal statement. Instead he 180'd so hard and fast you have to wonder if his activism was all grift from the get-go.

I don't say this as a glyphosate-basher. I say this as someone who'd prefer the HHS secretary was sincerely wrong than a con-man.

RFK was on a legal team that successfully sued Monsanto for causing cancer. He repeatedly called glyphosate a prime cause of our "chronic disease epidemic." His MAHA report in May tied it to "reproductive and developmental disorders as well as cancers, liver inflammation and metabolic disturbances."
