Coup D'état...


Topics: Civics, Civil Rights, Diversity, Existentialism, Human Rights, Politics

Blog break: 26 Nov - 7 Dec (finals, projects). There will be a break around Christmas into the new year. And after the new year:

KING HENRY V:
Once more unto the breach, dear friends, once more;
Or close the wall up with our English dead.
In peace there's nothing so becomes a man
As modest stillness and humility:
But when the blast of war blows in our ears,
Then imitate the action of the tiger;
Stiffen the sinews, summon up the blood,
Disguise fair nature with hard-favour'd rage;...

'Cry God for Harry, England, and Saint George!' speech of Shakespeare's Henry V, Act III, 1598.

Because apathy gives power to a demagogue. As he is wounded, and apparently moping, he will try something, ANYTHING to constantly change the subject during a creeping authoritarianism; (as Bill Maher said) a slow-moving coup.

Late night comedians are making great hay of this moment. It allows us to diffuse our angst in humor. Charlie Chaplin did so in 1940 with his self-produced speaking film, "The Great Dictator," Adolf Hitler personified in his cinematic character (and, Chaplin's obvious opinion of him) Adenoid Hynkel. That levity did not stop the coming atrocities, or the war.

The Trump administration is breaking with 75 years of precedent by attempting to interfere in how science is practiced by the U.S. government, according to three experts who issued a dire warning to their profession in the journal Science on Thursday. The administration is empowering political staff to meddle with the scientific process by pushing through reforms disguised to look as though they boost transparency and integrity, the experts say.

“It is tempting to conclude that recent proposals for reforming regulatory science are similar to what has occurred in the past,” they write. “They are not.”

“People who are not scientists are telling us how scientific synthesis and analysis should be done,” says Wendy Wagner, a professor of law at the University of Texas at Austin and one of the authors of the paper. “We’re not even getting scientists’ best work. We’re tying scientists’ hands behind their back and not even giving them a shot.”

“It’s a very dangerous place for science and public policy,” she told me. “Politics has gone to a place that should be off limits, and no one is noticing and calling them on that fact.”

Why are all these reforms so unprecedented? According to the authors, each of them places some stage of the scientific process under political direction. For decades, they write, the EPA and other federal agencies have followed a “two-step process” when consulting science: First, scientific staff have reviewed existing research and summarized and synthesized it for political staff. Then that political staff “can accept, ignore, rerun some of the analysis, or reinterpret the results.”

This process essentially erects an apolitical wall between the agency’s scientific staff and its policy makers, and it has been endorsed by the U.S. National Academy of Science, the authors say. But every single one of the proposed EPA reforms breaches that wall, allowing political staff to dictate the terms of scientific analysis and synthesis to scientists.

In his piece on Psychology Today, Eric R. Maisel, Ph.D. lists "What You Can Expect From an Authoritarian." The list is terrifying, but number 7: "Truth Held As Enemy - Authoritarians have little regard for the truth. If your agenda is to punish others because you are filled with hatred and anger, the truth of any particular matter is a mere inconvenience." This sums up the assault on legitimate news media and science. There is method to this madness.

Researchers at the Massachusetts Institute of Technology say they have discovered a new way to electrically control magnetism using a gate voltage that could be applied to a wide variety of magnetic materials, including oxides and metals. The “magneto-ionic” technique, which involves reversibly inserting and removing protons into the material structures, could help advance the field of spintronics (a technology that exploits the spin of the electron rather than its electrical charge) for the post CMOS-world.

Complementary metal-oxide semiconductor (CMOS) technologies are reaching the end of their road map and scientists are looking for alternatives to silicon microchips. Spintronics devices show promise in this context because they retain their magnetic state even when the power supply is switched off, something that it is not true for silicon memory chips. They also require much less power to operate and generate far less heat than their silicon counterparts.

One of the most important phenomena being studied in spintronics today is spin-orbit coupling, explains MIT Materials Research Laboratory co-director Geoffrey Beach, who led this research effort. “In many spintronics systems, emergent effects are generated at the interface between, for example, a metallic ferromagnet and a nonmagnetic heavy metal (like platinum or palladium),” he says. “Heavy metal/ferromagnetic interfaces have long been exploited to engineer magnetic thin films with perpendicular magnetic anisotropy, that is, films that spontaneously magnetize in a direction perpendicular to the film plane, which is required for most applications.”

Waltzing Nanoparticles...

Indiana University researchers have discovered that drug-delivering nanoparticles attach to their targets differently based upon their position when they meet—like ballroom dancers who change their moves with the music.

The study, published Nov. 13 in the journal ACS Nano, is significant since the "movement" of therapeutic particles when they bind to receptor sites on human cells could indicate the effectiveness of drug treatments. The effectiveness of immunotherapy, which uses the body's own immune system to fight diseases such as cancer, depends in part upon the ability to "tune" the strength of cellular bonds, for example.

"In many cases, a drug's effectiveness isn't based upon whether or not it binds to a targeted receptor on a cell, but how strongly it binds," said Yan Yu, an assistant professor in the IU Bloomington College of Arts and Sciences' Department of Chemistry, who led the study. "The better we can observe these processes, the better we can screen for the therapeutic effectiveness of a drug."

A bright laser beacon that announces our presence to extraterrestrial civilizations could soon be achievable, new research suggests. Calculations done by James Clark and Kerri Cahoy at the Massachusetts Institute of Technology suggest that current and near-future technologies could be used to produce light intense enough to be detectable to extrasolar astronomers as distant as 20,000 light-years away. The duo’s research also sheds light on how we could detect signs of intelligent life in star systems beyond our own.

For decades, some in the astronomy community pondered what would be the best way of communicating with intelligent alien life on distant planets. Once a purely academic question, the desire to communicate has been heighten recently by the ongoing discovery of large numbers of exoplanets orbiting stars other than the Sun.

Recently, two nearby exoplanets have proved particularly attractive for such efforts. These are Proxima Centauri b, a planet which lies in the habitable zone of our closest star just 4 light-years away; and the TRAPPIST-1 system, which at a distance of 40 light-years is believed to contain three potentially habitable exoplanets, are currently viewed as our best hopes for receiving replies to our messages.

Swine, Slop and Armistice...

As a United States Air Force veteran, I along with a roomful of others from the Army, Navy, Marines and Coast Guard were honored at Providence Baptist Church at their annual Veteran's Day breakfast. My fraternity brother, retired Staff Judge Advocate, US Army was the keynote speaker for the event. The southern breakfast of scrambled eggs, bacon and sausage; grits, fried apples and biscuits was quite good and filling. Later yesterday evening, my fraternity honored the veterans in attendance with a gift: a 50 caliber bullet made into an ink pen. I laughed, thinking what conversations it would generate at school. I as usual thought of my father, a WWII veteran from the then segregated United States Navy. I posted his youthful photo on social media to commemorate him.

As far as our current occupant of the presidency in America: There is no low for this man. He attacks three African American female journalists in a not-too-subtle wink at white nationalists and denigrates the firefighting efforts in Southern California via bombast and tweet, respectively. He could not afford to get his Propecia comb over wet during the 100th observance of Veteran's Day, or Armistice in Europe. It was the "war to end all wars" due to its carnage and horrific loss of life. Little did they know human depravity has an alarming tendency to top itself from its last offense, as the second would conscript my father and many other African American men that saw the danger of a worse racist nation actually winning the war to their own lives and their posterity. Since Orange Julius prides himself in not reading anything without his name in it, he's ignorant of the significance of his gaffs, unless they are purposeful to undermining this republic.

There was a desire, a longing for a "presidential pivot." We now see clearly he's as capable of that as a hog of showering off his own slop/feces: he sees no reason to change as the swine is comforted by the warmth of its own shit. Manure is his element: this is him.

The remarkable observation is the support (though dwindling) he still commands, which brings to question the depravity of our fellow citizens.

Deviant Confederates...

(noun): the fact or state of departing from usual or accepted standards, especially in social or sexual behavior.

This commentary is post the firing of Jeff Sessions, and the unconstitutional appointment of the sketchy Aryan bodybuilder Matthew Whitaker as opined by legal experts Neal K. Katyal and George T. Conway III (Kellyanne's husband) in the New York Times. My thoughts and articles I've excerpted follows:

Germany after WWII outlawed the public display of the Nazi flag or veneration of Adolph Hitler and other leaders in statues festooned across Europe because that’s what you do when trying to repent of war crimes, and absolve yourselves from crimes against humanity in the extermination of 6 million Jews as well as artists, gypsies, homosexuals and scientists.

There are obviously right wing extremists still in Germany and Europe as here. As a part of human society - manipulated and scammed by the rich that has always profited from such divisions - we likely always will have a deviant element.

We could minimize it however by agreeing on shared reality and not comfortable fables (“alternative facts”), teaching history In its proper context; the rights and responsibility of citizenship (Civics) and universal healthcare.

This is the only planet humans as far as we know have lived on. Since we’re 99% like ever other human in existence, we’d better start cooperating (an evolutionary survival trait) or expect extinction. It would be arrogance and hubris to expect anything else.

Then, there will be no “superior” left on a charred cinder.

The above commentary originally on Facebook (with modifications) is in reference to the article: "Picture showing voter wearing shirt with noose and rebel flag at the polls causes controversy," Troy Washington, WREG.com

What type of president looks at 14 mail bombs sent to public figures and 11 worshipers killed at a synagogue and gripes that these events disrupted his political momentum? Who would echo history’s worst leaders by calling the press “the true enemy of the people” and call migrants walking toward the U.S. an “invasion?” How does a man entrusted with the world’s highest office make 30 false or misleading claims every day?

As author of the most recent Trump biography, I’m repeatedly asked questions like those. In reply I rely on two old-fashioned terms. When it comes to his character, Trump is a deviant. When it comes to his conduct, he is a delinquent.

Even as a child in the 1950s Donald Trump showed a stubborn tendency to deviate from the very principles that underpin civilization. Trump explained to me in an interview that he felt most people are “not worthy of respect,” and this was the attitude he would carry through life. He never felt that the rules applied to him or that he should take responsibility for any harm he caused.

Trump’s deviant personality naturally led to delinquent behavior, including giving a teacher a black eye and continually refusing to comply with basic rules. “I was a very rebellious kid,” Trump told me. “I loved to fight.” More concerning was Trump’s suggestion that he hasn't changed since first grade. “The temperament,” he revealed, “is not that different.”

Fred Trump, his father, became so worried about his behavior that he sent 13-year-old Donald to military school. In those days New York Military Academy was, for kids like Trump, an alternative to a juvenile detention facility.

At the military academy Trump started out as defiant, especially compared with those he described as “normal kids.” When he conformed, he did it to manipulate. His mentor at the school said that Trump was the most “conniving” kid he ever met. After a baseball game, for example, he demanded a younger schoolmate agree that he had hit a home run that never happened. The boy, feeling the pressure, complied.

Who behaves like Trump? Deviants. And delinquents. Michael D'Antonio, The Los Angeles Times

“There have been many monsters in the past, but it would be hard to find one who was dedicated to undermining the prospects for organized human society, not in the distant future -- in order to put a few more dollars in overstuffed pockets.

And it doesn’t end there. The same can be said about the major banks that are increasing investments in fossil fuels, knowing very well what they are doing. Or, for that matter, the regular articles in the major media and business press reporting US success in rapidly increasing oil and gas production, with commentary on energy independence, sometimes local environmental effects, but regularly without a phrase on the impact on global warming – a truly existential threat. Same in the election campaign. Not a word about the issue that is merely the most crucial one in human history.

Hardly a day passes without new information about the severity of the threat. As I’m writing, a new study appeared in Nature showing that retention of heat in the oceans has been greatly underestimated, meaning that the total carbon budget is much less than had been assumed in the recent, and sufficiently ominous, IPCC report. The study calculates that maximum emissions would have to be reduced by 25% to avoid warming of 2 degrees (C), well above the danger point. At the same time polls show that -- doubtless influenced by their leaders who they trust more than the evil media -- half of Republicans deny that global warming is even taking place, and of the rest, almost half reject any human responsibility. Words fail.”


“In the 158th year of the American civil war, also known as 2018, the Confederacy continues its recent resurgence. Its victims include black people, of course, but also immigrants, Jews, Muslims, Latinos, trans people, gay people and women who want to exercise jurisdiction over their bodies. The Confederacy battles in favor of uncontrolled guns and poisons, including toxins in streams, mercury from coal plants, carbon emissions into the upper atmosphere, and oil exploitation in previously protected lands and waters.

“Its premise appears to be that protection of others limits the rights of white men, and those rights should be unlimited. The Brazilian philosopher of education Paulo Freire once noted that “the oppressors are afraid of losing the ‘freedom to oppress’”. Of course, not all white men support extending that old domination, but those who do see themselves and their privileges as under threat in a society in which women are gaining powers, and demographic shift is taking us to a US in which white people will be a minority by 2045.

“If you are white, you could consider that the civil war ended in 1865. But the blowback against Reconstruction, the rise of Jim Crow, the myriad forms of segregation and deprivation of rights and freedoms and violence against black people, kept the population subjugated and punished into the present in ways that might as well be called war. It’s worth remembering that the Ku Klux Klan also hated Jews and, back then, Catholics; that the ideal of whiteness was anti-immigrant, anti-diversity, anti-inclusion; that Confederate flags went up not in the immediate post-war period of the 1860s but in the 1960s as a riposte to the civil rights movement.”

Petrol, Wastewater and Membranes...

Argonne scientists have invented a membrane that, when exposed to sunlight, can clean itself and also actively degrade pollutants.

Critical tasks such as treating wastewater and processing petrochemicals rely on porous membranes that filter unwanted materials out of water. Over time, these membranes inevitably become clogged by bacteria or other substances, so they need to be replaced or cleaned with harsh chemicals that shorten their lifespan.

To address this problem, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have invented a membrane that, when exposed to sunlight, can clean itself and also actively degrade pollutants. The advance paves the way for membranes that can last longer and perform better than those in use today, lowering costs.

“Fouling is a longstanding challenge in membrane separations,” said Jeffrey Elam, a chemist in Argonne’s Applied Materials division. ​“This unique, multifunctional membrane is one way to combat that.”

The main ingredient driving this material’s pollutant-fighting abilities is a coating of titanium dioxide, widely studied for the purpose because it can accelerate chemical reactions when exposed to light. Typically for titanium dioxide, that light must be ultraviolet (UV) — a limitation that increases costs and narrows its feasibility.

Argonne researchers took two important steps to achieve sunlight-activated self-cleaning. First, they added small amounts of nitrogen to the titanium dioxide, ​“doping” it so that visible as well as UV light would bring out its photocatalytic properties.

Second, they used atomic layer deposition (ALD), a technique for creating thin films often used in the semiconductor industry, to place the coating on the membrane. Unlike the conventional method of dipping the membrane into a solution, ALD grows the coating one molecular layer at a time. This allows all of the membrane surfaces, including the internal nanopores, to be coated uniformly and precisely.
