Sandpiles & prophecy
Back in 1988, I began to come across both lay and professional works on self-organized criticality (SOC). This concerned a phenomenon in nature we probably all observed as children, namely how stacking rocks, pebbles, grains of rice or sand, or just about anything goes along smoothly until a “critical point” is reached in which the whole thing collapses (I often did the “stacking game” using small fossils I fished out of huge gravel piles at home construction sites close to the house where my family and I lived in Alexandria, Louisiana in the mid-1960s). A physicist, Dr. Per Bak, and two of his colleagues published a paper in 1987 which gave mathematical form and expression to this phenomenon, which like most successful explanatory works in science spread quickly and was applied to all kinds of “sandpiles” including neuronal networks in the human brain and the societies and civilization we have created. One academic, University of Melbourne professor of archeology, historical & philosophical studies Dr. Louise Hitchcock applied SOC to the collapse of societies and civilization. On 12-29-2020 an article came out titled Unprecedented’ new crisis coming: Covid-19 pandemic could be a warning for civilization – NZ Herald which looks at what lies ahead for us all in 2021 and beyond and includes input from Prof. Hitchcock.

This is simply too good to pass up:

People say, ‘Well, he lies about this, that, and the other.’ But no, he isn’t lying; to him, that’s the truth.” He said Trump has “done a marvelous job for the economy, but at the same time he is very erratic, and he’s fired people and he’s fought people and he’s insulted people and he keeps going down the line.” With Trump, “it’s a mixed bag,” Robertson said, “and I think it would be well to say, ‘You’ve had your day and it’s time to move on.'”
Stem cell therapy for Alzheimer’s disease. Does it work?
Many people have approached me over the years concerning friends, family members or others with Alzheimer’s disease. They all ask a simple question: can an infusion of adult (nonembryonic) stem cells slow, halt or even reverse AD? The qualified answer is: in animal models of AD, yes. In very preliminary human use experiments, yes, but even so what I’ve observed in AD patients treated with various kinds of adult stem cells experience is that their improvements are transient (The AD disease process undoes any gains over time — sometimes in a relatively short span of time).
There are some interesting stem cell based interventional strategies for remediating AD, some of which are outlined in this August 2020 paper: Stem cell therapy for Alzheimer’s disease (nih.gov). This statement in the abstract is very telling: “….many steps still need to be taken before stem cell therapy becomes a clinically feasible treatment for human AD and related diseases. This paper reviews the pathophysiology of AD and the application prospects of related stem cells based on cell type”.
