Ethnobotanical Toxicology

L-Serine is classed as a non-essential proteinogenic amino acid, because under "normal physiological conditions" the body can synthesise it from other metabolites, including glycine. But in some circumstances this synthesis is insufficient [see L-Serine: a Naturally-Occurring Amino Acid with Therapeutic Potential]. β-Methylamino-L-alanine (BMAA), a non-proteinogenic amino acid, is a neurotoxin produced by cyanobacteria and has been implicated in some neuro-degenerative diseases:

I saw this in the Cambridge newspaper this morning:

See Over 20,000 people join search for new dementia treatments.  To me this study just sounded like an attempt to reduce medicine to an exercise in actuarial statistics and genome sequencing, but if they can connect their analysis with studies like this one of Paul Cox's then it could become something much more interesting.

David Turner Obituary by Sarah Nicholas Fri 24 Nov 2023

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory Illinois. Did

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ... Sounds like Edith (II) Rix has been online all the time, ...
