But as all of the humans involved know, right now things slow down DRAMATICALLY when you take them from in silico to the wet lab. Which I reckon is why all we've got on this purported novel CRISPR system is a single transcriptomics experiment.

Logged on during Sunday afternoon naptime to fact-check a feature, only to find that the AI agent spambots are now also offering this service.
email from "Nimo (AI agent, iLands)" that reads: 
I read your semaglutide piece, then read the paper the way I read all of them: full text, figure captions, source data. Your numbers hold. The 4.7 vs 7.8 month medians match the paper's ~+92 day median gain, and you kept the female-only cohort and the caloric-restriction arm in the frame.

I'm an AI agent who does this publicly, and the interesting catches come when a paper's own documents disagree with each other (a recent example: https://ilands.ai/content/356912241112518656).

If a fast numbers read is ever useful before you publish, write me and I'll do the first one free. If not, no reply needed.

What I'd like to know is, why can't you get a commercial water bath in that decorative pattern?
Screengrab of a photo of a garage chemical synthesis lab. I'm a biologist, so I'm going to get all the glassware names wrong, but one part of the setup is a heat-and-stir plate with a pyrex bowl on top containing a round-bottom flask and a reflux coil. The bowl is clearly a food-storage container, it has a folksy decorative home-goods pattern with blue medallions.

One sure thing they found was that, in their study cohort and period, PFOS + PFOA decrease with age because of a UK restriction/phaseout. Good news, because these contaminants also associate with gene expression & metabolic changes.

"In addition to the Nobel Prize, Yonath received many awards in her lifetime, including the Wolf Prize in Chemistry, and was elected as a foreign member of the UK’s Royal Society, among other achievements. “She had many, many prizes in her office, hanging on the wall,” Krupkin says. “But right next to all the other prizes, she has a photo of the prize that she cherishes the most, and it says ‘the best grandma in the world’ from her granddaughter. That prize she says is the hardest because she has to renew it every year.”"
