It’s a spectrum and it has certainly moved

I believe it’s important that all Americans remain abreast of official White House communications.

The Voice of our democratic republic is being used for petty cult.

Meantime health research administrative staff has been cut so heavily that not a single contract can be executed.

“There is an evil which I have seen under the sun, as an error which proceedeth from the ruler: Folly is set in great dignity, and the rich sit in a low place.

“The words of wise men are heard in quiet more than the cry of him that ruleth among fools.”

—Ecclesiastes 10:5–6, 9:17

Great to see Taiwan’s 唐鳳 Audrey Tang @audreyt.org justly celebrated in Nexus, the latest book from Yuval Noah Harari.

A full day with the Constitution. Have you read it? What did you find most surprising about it?

Officially a genocide.
nytopinion.nytimes.com
“Israel has committed genocide against Palestinians in Gaza. This finding is based on investigations and extensive evidence,” writes Navi Pillay, the head of a U.N. commission. “It has been corroborated by multiple sources.”
Opinion | My U.N. Commission’s Finding: Israel Is Committing Genocide
The chief judge of the Rwandan genocide tribunal has concluded that Israel is guilty of the “crime of crimes” in Gaza.

Thank you so much for the thoughts, Justin! I'm definitely on the same page about technical science work—specificity and formality is great. But I look at a bunch of science and other lay audience books and it seems like almost no one uses the middle initial, making me second guess things!

Dear friends, I’d love your input: I’m planning to submit some writing to a general-audience magazine and I’m torn about how to sign my name. Which feels better to you and why?

Delighted to see our paper on the evolutionary history of the CCR5Δ32 deletion published this week in @cellpress.bsky.social. Work led by @ravnkirstine.bsky.social, Leonardo Cobuccio and Rasa Muktupavela, and co-supervised by me and @simorasmu.bsky.social. See 🧵 for main findings...
Graphical abstract: The chemokine receptor variant CCR5delta32 is linked to HIV-1 resistance and other conditions. Its evolutionary history and allele frequency (10%–16%) in European populations have been extensively debated. We provide a detailed perspective of the evolutionary history of the deletion through time and space. We discovered that the CCR5delta32 allele arose on a pre-existing haplotype consisting of 84 variants. Using this information, we developed a haplotype-aware probabilistic model to screen 934 low-coverage ancient genomes and traced the origin of the CCR5delta32 deletion to at least 6,700 years before the present (BP) in the Western Eurasian Steppe region. Furthermore, we present strong evidence for positive selection acting upon the CCR5delta32 haplotype between 8,000 and 2,000 years BP in Western Eurasia and show that the presence of the haplotype in Latin America can be explained by post-Columbian genetic exchanges. Finally, we point to complex CCR5delta32 genotype-haplotype-phenotype relationships, which demand consideration when targeting the CCR5 receptor for therapeutic strategies.

Headed to Bangkok, Thailand 🇹🇭 Oct 23–26 for a science conference. First time. If I add 1–2 days, what should I not miss? 🙏

It is not the bigness of our concern for certain lives, but the smallness of our concern for countless others, that stands correction.

Darwin described characteristics that revert or evolve to the same state—what we refer to as homoplasies—as “mocking” each other. I appreciate this description. I often feel they are mocking me.

The United States is arming a terrorist regime that has the audacity to call itself Israel.

In the words of Lieutenant Colonel Anthony Aguilar, a 25-year U.S. Army Green Beret: “the people back home need to know they’re funding a genocide.” www.nytimes.com/2025/09/05/w...
