This is a better summary than anything I've seen in mainstream or alternative media. Essential reading.
I’ve unfortunately needed to add more material to my post from yesterday. The re-election of Donald Trump is looking like the biggest act of American self-destruction since the Civil War.

Literally every time I have filed this story (4x this week), something happened to change it before my editor had a chance to look.

But here’s WTF happened at NIH this week (so far)

MS protein analysis—I’m one of many to follow in his footsteps. Great NIH program officers are the backbone of the extramural system. I owe much to several of them over the years.

Just because a paper is highly cited, it doesn’t mean it is correct or truthful. This paper (www.nature.com/articles/nat...) was cited 4504 times and yet it was retracted.

There is no penalty for non-compliance. It’s just that someone someday will probably report it to the editors. 1/2

Mark, with all due respect. Sit down and visit with some folks who are intimately familiar with the NIH, the scientific process, how grants are handled and funded.

The NIH is not a business. There are no shareholders. There is no mandate for profit. This is not a business model and should not be.
Trump is doing what you do after you acquire a company. Crazy I know. But reality. The Dir of NIH should reach out to DOGE and offer to bring them in to remove inefficiencies.

There are always some and the Director know what they are.

DOGE gets a win. NIH gets back to work.
Hi Mark, how do you feel about cancer research being canceled.

Skimming through the latest paper journals plays a catalytic role in a fascinating decades-long friendship that Roald Hoffmann had with two Chinese chemists, Tang Ao-Qing and Lu Jiaxi.

Beautiful work - I love the analysis of organelle rearrangement in response to changes in lipid flux.
Preprint alert!! How zonated hepatocytes adapt to changes in lipid influx due to fasting or a Western diet (WD). We developed a microscopy-based phenotyping method called single-cell phenomics (scPhenomics) to measure the features of mitochondria and lipid droplets (LDs).

i do find it interesting in a bleak way that silicon valley is basically recapitulating 1920s-style american reactionary politics.
The tech bro fascination with eugenics is so on brand. The idea that you could make accurate, actionable predictions from individual genotypes (with all their complex, non-linear interactions) from averaged, linearly modeled population-level genomic statistics is just another big data fantasy

I remain impressed that this got published in a high-profile journal. Most med chemists have a visceral, well-founded negative reaction to those structures. I wish we could teach our bio colleagues the structural spidey sense. Tip of the iceberg here when it comes to setting the record straight.

You'll notice proteomics has tighter CVs and higher correlation between the cells. Also the average proteome to transcriptome correlation is low (~0.35). Really nice to see this quantified clearly
