Social Evolution

Speaking of monopolies (see previous post),

Some cell behaviors – especially those that give the cell group its ability to exploit environmental resources – are cooperative in nature . . . . When genetic relatives are clustered together, cooperative cell behaviors like extracellular enzyme secretion can evolve more easily. Secreted enzymes, in turn, may allow a pathogenic bacterial colony to become more virulent, or a nascent cancerous tumor to become malignant.

. . . . In the three images shown here, the red and blue cell types do not differ in any way other than their color, which is used to determine whether a cell group remains well-mixed, or whether related cells tend to cluster together.

From left to right, environmental nutrient concentration was decreased from ubiquitous, to moderate, to sparse. As nutrient concentration decreases, the tendency for different genetic lineages to spontaneously segregate increases, which favors the evolution of cooperation.

Last time I checked online for blood cell animations, pickings were slim. Now one need look no further than YouTube. I rec. you get as many onscreen as possible (these are formatted so that, if you have the option of making this window big enough, you can get a nice, tight 3 x 3 array of embeds), play them all simultaneously, here or otherwise, then click replay as needed to keep them all going for a bit (audio desirable). (Happy Halloween.)

UPDATE: I made a vidi of my own results here.

Thoughts for the year or whatever, in no particular order:

What a huge debt this nation owes to its "troublemakers." From Thomas Paine to Martin Luther King, Jr., they have forced us to focus on problems we would prefer to downplay or ignore. Yet it is often only with hindsight that we can distinguish those troublemakers who brought us to our senses from those who were simply troublemakers. Prudence, and respect for the constitutional rights to free speech and free association, therefore dictate that the legal system cut all non-violent protesters a fair amount of slack.
– Justice Sonia Sotomayor, writing for the Second Circuit Court of Appeals in Papineau v. Parmley, 465 F.3d 46 (2d Cir. 2006).

On the one hand, information wants to be expensive, because it's so valuable. The right information in the right place just changes your life. On the other hand, information wants to be free, because the cost of getting it out is getting lower and lower all the time.
– Stewart Brand to Steve Wozniak, at the first Hacker's Conference in 1984, per Roger Clarke.

A modern economic system demands mass production of students who are not educated and have been rendered incapable of thinking.

Nothing is inevitable, except defeat for those who give up without a fight.

Why of course the people don't want war. Why should some poor slob on a farm want to risk his life in a war when the best he can get out of it is to come back to his farm in one piece? . . . But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy, or a fascist dictatorship, or a parliament, or a communist dictatorship. . . . All you have to do is tell them they are being attacked, and denounce the peacemakers for lack of patriotism and exposing the country to danger.
– Hermann Goering, per Nuremberg Diary (Farrar, Straus & Co 1947), by Gustave Gilbert

The war is not meant to be won. It is meant to be continuous.

[W]e forgot that the question is NOT, how do we get good people into power. The question is, how do we limit the damage the powerful can do to us?

One sits and beats an old tin can, lard pail.
One beats and beats for that which one believes.
That's what one wants to get near. Could it after all
Be merely oneself, as superior as the ear
To a crow's voice?
– Wallace Stevens, The Man on the Dump (1923).

It's class warfare, [and] my class is winning, but they shouldn't be.
– Warren Buffet, CNN Interview, May 25 2005, suggesting we need to raise taxes on the rich.

The past is never dead. It's not even past.
– William Faulkner, Requiem for a Nun, Act I, scene iii (1951).

Cui bono (To whose benefit)?
– attributed by Marcus Tullius Cicero to Lucius Cassius Longina Ravilla, ca. 125 B.C.

thinking to bring you news
of something
that concerns you

yet men die miserably every day
for lack
of what is found there.
