Nano Zappers...

One potentially valuable way to attack cancer cells is to zap them with low-intensity alternating current. This interferes with the flow of calcium and potassium ions in and out of the cells, a process so important that disrupting it ultimately kills them.

But there is a problem with this approach: healthy cells are just as susceptible to ion channel disruption as cancer cells, so the treatment kills healthy and cancerous cells alike. What’s needed is a way to focus the treatment on cancer cells while leaving the healthy ones untouched.

Enter Attilio Marino at the Istituto Italiano di Tecnologia, Enrico Almici at the Polytechnic University of Turin, and colleagues in Italy. These guys use piezoelectric nanoparticles that generate current inside the body when repeatedly compressed with ultrasound. And they have gathered the first evidence that this could be turned into an effective treatment for cancer.

The technique is straightforward in theory. Piezoelectric materials generate a charge when squeezed (and similarly change shape when zapped with a voltage). They are widely used in everything from microphones to motors.

Marino and co’s idea is to inject biocompatible nanoparticles into the body and then bombard them with ultrasound. The high and low pressures associated with the ultrasound should cause the nanoparticles to generate a charge that interferes with ion channels and kills the cells. The team choose barium titanate nanoparticles, which are considered biocompatible since they contain no lead.

Multi Messenger Astronomy...

Within 12 hours observatories had identified the source of the event GW170817 within the galaxy NGC 4993 – shown in this Hubble Space Telescope image – and located the associated radioactive emissions, or “kilonova”. Hubble observed that flare of light fade over the course of six days, as shown in these observations taken on 22, 26 and 28 August (insets).

Congratulations to Imre Bartos, whose article "A new cosmic messenger" has been picked as one of Physics World's five favourite features of 2018. Taken from the January 2018 issue of Physics World. Members of the Institute of Physics can enjoy the full issue via the Physics World app.

The first observation of gravitational waves from two merging neutron stars that was recently made by the LIGO and Virgo detectors has – along with data from telescopes across the globe and in space – kicked off a new era in multimessenger astronomy. Imre Bartos describes this watershed moment, which crowned decades of research and will shape the future of observational astronomy.

It was almost over. There was only one week to go before the Advanced LIGO and Virgo detectors would complete their observational run, and be shutdown for a year. Indeed, many of my colleagues from the LIGO–Virgo team were already on vacation, while I was awaiting relatives who were visiting. Then my phone buzzed. An automated text message, which read “ALERT FROM GWHEN | New event: G298048 | Check your email!” prompted me to rush to my computer, to look at the signal in a LIGO database. When a flurry of agitated phone calls from collaborators followed, it became clear that a historic moment was unfolding. We observational astronomers needed to act quickly, and as our findings were still a secret, I couldn’t even tell my relatives, who had arrived in the middle of the excitement, why I would need to work.

On 17 August 2017 the LIGO detectors in Louisiana and Washington detected gravitational waves from the collision of two neutron stars – ultracompact dead stars that weigh as much as our Sun, but are barely 20 km in diameter, roughly the size of Manhattan. Such an event had been anticipated for decades, but had never been observed until now. Within two seconds of the arrival of gravitational waves at LIGO, NASA’s Fermi Gamma-ray Space Telescope detected a short gamma-ray burst. This made it even clearer: the gravitational-wave detection – dubbed GW170817 – was not a false alarm, and observatories across the globe quickly needed to turn towards the direction of the collision, or the data would be lost forever. More than 70 telescopes and observatories around the globe and in space were rapidly notified, and were able to execute a co-ordinated survey of the merger and its aftermath, across the full electromagnetic spectrum – gamma-rays, X-rays, light, radio waves – and neutrinos. A new era in multimessenger astronomy had begun (figure 1).

What did we learn?

Neutron-star mergers may be the main source of heavy elements in the universe.
The expansion of the universe can be measured by neutron-star mergers,
We have a new upper limit on the mass of neutron stars.
The neutron stars in GW170817 orbited each other for billions of years before colliding.
The colliding neutron stars created a gamma-ray burst.
There’s something strange about the energetic jet.

Intelligent Collectors encouraged!

Posted by Turtel Onli on January 2, 2019 at 8:32am

The fact that most indie Black Age publishers produce limited editions or small press runs insures the collector will likely have a rare item to treasure. Future speculative investors, auctions and collectors, once its time has come, will pay dividends to acquire items from this extended important era in this industry. Seeing "Black" as investment value or prestige is growing beyond the realm of that which comes from the mainstream. Most will be left saying...."I had those Black Age books...I didn't ever think much of them. Damn!"

Anyone See the Grinch's Comet?

Posted by Ms. Regina Owens on December 21, 2018 at 5:30pm

The past weekend something spectacular supposedly had appeared in the skies above planet earth.Astronomers and the folks at NASA had charted out on December 16, a greenish, blobs like comet could be seen making a close approach to earth on December 16.The comet supposedly moves closer to earth a trifle closer than the Moon, so close the greenish comet on that night could be seen with the naked eye. The particular,greenish comet is known as tube "Wirtanen,"one,and on December 16 any persons wanting to view tube comet, there were watch gatherings set up in different areas of America to view, the flashing green comet. Now,in The as the weather is mild in during the days and a smidgen cooler at night,but where I live there are lights too numerous makes the viewing of the green comet not too clear. However,in case some of us other folks on planet earth missed, "the Grinch's comet,"well according to NASA, the Wirtanen,the true name of the comet will not make another flashy,green show until another twenty years,and the Grinch would be possibly nearing the age of say 90 years old?

Control and Chaos...

Note: Enjoy the holidays. I'll be on break until 7 January 2019.

"He's a 'Chaos Candidate' and He’d Be a 'Chaos President,'" former Florida Governor John Edward ("JEB") Bush in an alarmingly accurate moment of prescience.

Maxwell Smart, a.k.a. Agent 86, works for CONTROL, a Washington, D.C.-based counterintelligence agency. Totally inept as a secret agent, Smart can barely use the gadgetry the agency provides him (including a phone embedded in his shoe). Nevertheless, he and his fellow agents always seem to thwart the operations of KAOS, an organized crime outfit dedicated to evil. Agent 99 is Smart's smarter partner, a resourceful agent who eventually marries her bumbling cohort. Smart and Agent 99's boss is a man known only as The Chief. Source: Google users search

His "charity" has met the fate of his "university": eventual oblivion. The market has erased all its gains in 2018 in November, and it doesn't show any signs of slowing down. We are at this posting, hours from a reality TV inspired government shutdown that the current occupant of the Executive Mansion proudly owned to the surprised delight of "Nan-Chuck-Ku," who needed no mental Jujitsu to outwit a nitwit. Michael Cohen is "rat" and Michael Flynn a "saint," at the moment - the jury's still out on Roger Stone. With his 3-month delayed Mulligan sentence to think about Flynn and his lawyer's cute "perjury trap" stunt and Judge Sullivan's disgust, he'll likely be Mus musculus by poetically, the Ides of March and a morning bowel movement/Twitter rant. Wired published a complete guide to 17 investigations related to him. So...much..."winning."

"Who's going to pay for the wall? MEXICO!"

This was the refrain at rallies before and after the election. It was shtick; an applause line that appealed to his audience's racism and xenophobia. He embarrassed himself literally begging the previous Mexican president, Enrique Peña Nieto to fund it, who patently refused. Now he's demanding 5 billion dollars - an arbitrary number I'm certain - or, the equivalent of a screaming match from a toddler ensues. A toddler that until January has control of the Executive Branch, Supreme Court, the Senate and the House he lost in the midterms. Mattis is out; and the stock market is in free fall. So a shutdown is the chaos that goes down well, in the spirit of the season with sugar, coal and golf at Mar-a-Lago. The secret service will by duty protect him, albeit unpaid.

New Knowledge published a White Paper "The Tactics and Troupes of the Internet Research Agency." You should read it. We all should read it. At 101 pages, it's shorter than a novel. At 10 pages a day, you could have it finished in over a week. The social media companies have always made money on the aggregation of information our behaviors log on their platforms. They then sell that typically to companies. It's why your "like" of something on social media turns up on Amazon or other websites as an associated product to sell you. It's not too far a reach to speculate they'd sell it to governmental agencies, or extra-governmental agencies (i.e. "spies"), some interested in exploiting the fissures in our society. If the most famous democratic republic in history falls, it's dominoes across the planet. We are literally, the linchpin to chaos.

I participated in the Facebook boycott, adding Twitter and Google since those are the main platforms I use. Before we wait on the slow grind of government to finally regulate social media companies, we should regulate our own behaviors. They gather that aggregate data by the sheer number of times we engage their platforms, typically now through social media apps on our mobile phones. Rather than a single day's abstinence, why not delete the apps from our phones? That is what I did. I imagine it would cut engagement times from a surprising number of hours to minutes. I think you'll find yourselves less distracted, and like I said, it's an easy, voluntary implementation. The companies will regulate themselves to survive and get some of your business back.

My theory of the case is simple: he never meant to win, and Putin never envisioned him winning. His biggest fear isn't pee tapes, but that Putin knows his actual net worth (which we'd know if he released his taxes). He wanted to hamper his opponent - who he really hated - from implementing her agenda. It's why he has that Cheshire cat smirk every time he and Orange Doofus are in the same room: he despises him, thinks he's an idiot and the pee tapes are probably on permanent loop at the Kremlin with Vodka and laughter. And like a cat, Cheshire or otherwise, he's playing with his prey before he's done with it. Any collusion by his Keystone Cop campaign was clumsy and stupid. It's why the tower in Russia was still on the table. His payoffs of an adult film star and a Playboy centerfold was pure ego. The affairs happened years before: If he was going to lose, he WASN'T going to lose for that! Though, he would rather have lost, and just not admitted to losing. Then he could scream from the bleachers "the system is rigged," get another Apprentice gig and his own Faux News 2.0 station with his buddies Sean Hannity and Bill O'Reilly.

It was the PERFECT plan...until he won.

Sudoku and Velocity Fields...

Posted by Reginald L. Goodwin on December 20, 2018 at 6:30am
Image Source: Link below

Topics: Materials Science, Probability, Radiation, X-rays

To see what happens inside a pile of sand or another volume of granular material, researchers rely either on deformation observations at the surface, which don’t always reflect any internal flows, or on simulations. Several existing techniques can image interior flows, but they each have one or more disadvantages, such as limited spatial and temporal resolutions, high costs, and invasiveness. A new technique, developed by James Baker, Itai Einav, and their colleagues at the University of Sydney, overcame those hurdles by using sets of two-dimensional x-ray radiographs to uncover the three-dimensional velocity field inside a volume of opaque grains.

X rays were fired from three orthogonal locations through a container of opaque grains that were being sheared from below by a conveyor belt, as shown in the diagram above. By spatially correlating successive radiographs, the researchers extracted the probability density functions (PDFs) of the two displacement components orthogonal to the x-ray direction for each grid cell. Each PDF was then sampled evenly to generate an unsorted array of the different displacements through the beam direction.

By combining the PDF results orthogonal to each other and solving a Sudoku-style puzzle, the researchers were able to reconstruct the 3D velocity field shown from 2D projections. As in Sudoku, the displacement values that should be placed in each row and column are known from the two sets of PDFs, but how to arrange those displacements in space defines the puzzle. Unlike in Sudoku, though, there is no unique solution.

"Then I saw 'a new heaven and a new earth,' for the first heaven and the first earth had passed away, and there was no longer any sea." Revelation 21:1

The Arctic is continuing to warm twice as fast as the rest of the planet; air temperatures every year from 2014 to today have been warmer than all previous records since 1900.

The reasons for this trend include less snow and ice to reflect sunlight, warmer oceans releasing heat into the atmosphere later into the fall, and increasing winter cloudiness, according to the US National Oceanic and Atmospheric Administration (NOAA).

NOAA released its 13th annual Arctic Report Card, synthesizing the peer-reviewed work of 81 scientists from 12 countries, on 11 December 2018 at the American Geophysical Union (AGU) Fall Meeting in Washington, DC. The report sounded warnings about the current effects of Arctic warming in such diverse fields as caribou populations and poisoning of shellfish.

Emily Osborne, who heads NOAA’s Arctic research programme, told reporters at AGU that the higher air and water temperatures are pushing the Arctic into uncharted territory. The average temperature this past year was 1.7 °C above the long-term average, she said, and an unusually sluggish and wavy high-altitude jet stream coincided with a heat wave at the North Pole and a swarm of severe winter storms in the eastern US.

Animals famous for walking up walls can also use a combination of techniques to race across water.

The flat-tailed house gecko can not only stick to walls and glide through the air, but also run on water, a new study finds. This discovery of the combination of techniques the reptile uses to race across water could one day lead to robots capable of the same feats, researchers said.

The flat-tailed house gecko (Hemidactylus platyurus) is a common pet reptile native to southern and Southeast Asia. Not only can bristles on its toes help it climb walls and hang from ceilings, but it can glide with the aid of its webbed feet and skin flaps. "They're kind of like superheroes -- every time you look at them, they can do more things," said study senior author Robert Full, an integrative biologist at the University of California, Berkeley.

The newfound talent of this species was discovered by study co-author Ardian Jusufi, a biophysicist now at the Max Planck Institute for Intelligent Systems in Stuttgart, Germany, when he was in a rain forest in Singapore and saw the geckos skidding across puddles to escape predators. Lab experiments with these reptiles found they could run up to nearly a meter per second over 8 centimeters of water, faster than the swimming speeds of many aquatic creatures, including ducks, muskrats, juvenile alligators and marine iguanas. They could also easily switch to dashing across solid ground or scampering up a wall.

Conjuring Ray Palmer...

A new 3D nanofabrication technique called Implosion Fabrication could be used to create a wide variety of nano- and microstructures not previously possible. The technique, which can print 3D objects of nearly any shape by patterning a polymer scaffold with a laser and then shrinking the structure to a thousandth of its original volume, might be used to make novel optical metamaterials and electronics devices.

Shrinking hydrogel scaffold
Most existing nanofabrication techniques are limited in what they can produce. Direct laser writing methods, for example, can produce 2D patterns but not 3D ones, which need to be built up a layer at a time – a process that is difficult and slow. Lithography, one of the oldest nanofabrication techniques, can again only print 2D layers on patterned surfaces.

The apropos cultural reference that absolutely dates me!

Damnatio memoriae...

Posted by Reginald L. Goodwin on December 14, 2018 at 6:30am

Topics: Civics, Existentialism, Humor, Politics

Damnatio memoriae is a modern Latin phrase meaning "condemnation of memory", i.e., that a person is to be excluded from official accounts. There are and have been many routes to damnatio, including the destruction of depictions, the removal of names from inscriptions and documents, and even large-scale rewritings of history.

In Latin, the term damnatio memoriae was not used by the ancient Romans. The first appearance of the phrase is in a dissertation written in Germany in 1689. The term is used in modern scholarship to cover a wide array of official and unofficial sanctions whereby the physical remnants of a deceased individual were destroyed to differing degrees.

Damnatio memoriae, or oblivion, as a punishment was originally created by the peoples of Ephesus after Herostratus set fire to the Temple of Artemis, one of the Seven Wonders of antiquity.[citation needed] The Romans, who viewed it as a punishment worse than death, adopted this practice.[citation needed] Felons would literally be erased from history for the crimes they had committed.[citation needed] Wikipedia

Apparently I have a few fans on the site Black In America dot com, a forum started by Soledad O’Brien when she was an anchor at CNN:

Another idiot is Mr. Reginald Goodwin! He’s always criticizing Pres. Trump, but I logically know this!
I am positive that Mr. Goodwin voted for Hillary Clinton and this is my argument.
If Mr. Goodwin was as smart as he think he is he would have reasoned like I did that Mr. Trump would be White America’s 45th president. Instead, the idiot Mr. Goodwin comes on Black in America and trash Pres. Trump for winning proving that Mr. Goodwin isn't smart at all since he voted for the wrong candidate, Ms. Hillary Clinton!

The policies that Mr. Trump campaigned on I reasoned Mr. Trump would win and that did happen, Mr. Trump won!

Mr. Goodwin is an idiot and I can say he is because I've proven he is since he voted for the wrong person and is now trashing the candidate that won, that is not intelligence!

Despite calling me out with an insult, I'm judiciously protecting this person's privacy. I'm obviously being facetious about his fandom. From his own words, we know who he's a fan of.

A few points before my retort:

2. The Mueller indictments so far: Lies, trolls and hacks, Jesus Rodriguez and Beatrice Jin, Politico
3. Mueller Indictments: Who’s Who, Wall Street Journal
4. Quoting myself in the post Belief in Oneness:
65,853,625 voted for the sane (though, maybe not desired) candidate.
62,985,105 voted for the orange fascist tweeting on the loo and defecating from his pie hole in a breathtaking achievement of daily, all-time Olympic-level lying.

Note: I was Who's Who For Colleges and Universities in my undergraduate days; International “Who’s Who” of Professionals 1998, volume 3 - page 2-47. I've never aspired however, to be on Director Robert Mueller's "Who's Who."

In response, I'm positive I voted for Secretary Clinton too. I'm pretty certain I did (my candidate is saner, and makes complete sentences on and off Twitter). I also don't think she's so much of a narcissist to call for a civil war if removed from office. He's Vladimir Putin's orange wet dream.

My retort (curt and to-the-point):

Who the hell are you, and why should I care? Take your meds and go back to bed, idiot. A prophet you're not, and a profit you've yet to net from your asinine comments. Enjoy oblivion as you will now be blocked and your insane commentary you can keep to yourself. Monday, December 10th 2018 at 1:52 PM

My troll posits himself a "prophet," a title I suspect he's assigned himself and is probably as accurate as Ms. Cleo, may she rest in peace, not speaking ill of the dead.

So, my response was to use the site's tools to block him. Because I've blocked him, he can only fume, post, spit at me from cyberspace and I won't respond or care. I do sincerely hope he takes his meds.

Lastly, I think damnatio memoriae is apropos once we are all post this era of Tweets, insults, incitements, indictments, arrests and Russian collusion. Oblivion should be his purgatory and zero access to the Internet. Like the Witch in the "Wizard of Oz" and my disturbed troll that is his fan: Entropy will allow him to shrivel and die alone and ignored, a Twitter account archived; no presidential library commissioned, bald; bereft of ferret toupees and tanning beds in something beyond hell and pee-pee tapes he would loathe above all else - obscurity.

Measuring Cosmic Distances...

Image Source: Link below

Topics: Astrophysics, Black Holes, Cosmology, Gravitational Waves, LIGO

Decades of experimental effort paid off spectacularly on 14 September 2015, when the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) spotted the gravitational waves generated by a pair of coalescing black holes.1 To get a sense of the effort leading to that breakthrough, consider that the gravitational waves caused the mirrors at the ends of each interferometer’s 4 km arms to oscillate with an amplitude of about 10−18 m, roughly a factor of a thousand smaller than the classical proton radius. The detection was also a triumph for theory. The frequency and amplitude evolution of the measured waves precisely matched general relativity’s predictions for the signal produced by a binary black hole merger, even though the system’s gravity was orders of magnitude stronger than that of any system that had been precisely probed before that detection.

Labeled GW150914, that first reported event was soon joined by other detections of binary black hole mergers. Each of those events appeared to be totally dark to traditional astronomical instruments—the matter and electromagnetic fields near the merging black holes were not sufficient to generate any signal other than gravitational. As had long been promised, gravitational waves have opened a window onto an otherwise invisible sector of the universe.

In a discovery that could pave the way for new materials and applications, materials scientists at Rensselaer Polytechnic Institute have found that oscillating loads at certain frequencies can lead to several-fold increases in the strength of composites with an interface that is modified by a molecular layer of "nanoglue."

A newly published article in Nature Communications reports the unexpected discovery of the effects of loading frequency on the fracture energy of a multilayer composite involving a "nanoglue," the use of which was also pioneered at Rensselaer.

"Unearthing, understanding, and manipulating nanoscale phenomena at interfaces during dynamic stimuli is a key to designing new materials with novel responses for applications," said Ganpati Ramanath, the John Tod Horton Professor of Materials Science and Engineering at Rensselaer and the lead author on the study. "Our work demonstrates that introducing a nanoglue layer at an interface of a layered composite can lead to large mechanical toughening at certain loading frequencies."

The Perfect Fluid...

Posted by Reginald L. Goodwin on December 11, 2018 at 6:30am
If collisions between small projectiles -- protons (p), deuterons (d), and helium-3 nuclei (3He) -- and gold nuclei (Au) create tiny hot spots of quark-gluon plasma, the pattern of particles picked up by the detector should retain some 'memory' of each projectile's initial shape. Measurements from the PHENIX experiment match these predictions with very strong correlations between the initial geometry and the final flow patterns. Credit: Javier Orjuela Koop, University of Colorado, Boulder

Topics: Astrophysics, Fluid Mechanics, Nuclear Physics, Relativity, Theoretical Physics

Nuclear physicists analyzing data from the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at Brookhaven National Laboratory—have published in the journal Nature Physics additional evidence that collisions of miniscule projectiles with gold nuclei create tiny specks of the perfect fluid that filled the early universe.

Scientists are studying this hot soup made up of quarks and gluons—the building blocks of protons and neutrons—to learn about the fundamental force that holds these particles together in the visible matter that makes up our world today. The ability to create such tiny specks of the primordial soup (known as quark-gluon plasma) was initially unexpected and could offer insight into the essential properties of this remarkable form of matter.

"This work is the culmination of a series of experiments designed to engineer the shape of the quark-gluon plasma droplets," said PHENIX collaborator Jamie Nagle of the University of Colorado, Boulder, who helped devise the experimental plan as well as the theoretical simulations the team would use to test their results.

Assault of the Mainstream

Posted by Turtel Onli on December 6, 2018 at 9:10am

Now that the Mainstream has tried and failed to take the life force outta the growing indie-Black age movement with its "afro-futuristic" blockbuster along with its here today-gone tomorrow great token Hero of Harlem, who among us is really about winning at  this challenge and profiting from the opportunities it presents?

Their best efforts to corner and control the Black Age is my proof that we are actually winning in this war for minds and market shares.....inspite of addictive  brand loyalty...the Black On Black boycott....and culturally based anti-intellectualisms.  I often present on panels.....over the years since 1992....at San Diego,,,,,Wizards.......C2E2.....on the Black Age or diversity....  Usually with a lame unprofessional uninformed person in charge.  Each time some hater stands up to taut how racist the Black Age is and how he of she gets so much more outta Manga/Anime'.

Sort of like all of the Black folks that spent 8 years complaining about how President Obama wasn't Black enough instead of helping to make things betta....

OK. I know a lot of folks wanna grow up and become Ninja-Girls.....but has anyone ever noticed the names in the credits? All Japanese.  Behind that industrial smile is a hand all the way in their bank accounts and a grin that is saying..."Sucker"!.

Now I totally support with money, time and praise, all Brothers & Sisters that make money in the mainstream.  That is as god as cash and them and their successes matter too!

Then the ones who wish the mainstream would create something betta they could relate to......but in both cases not wanting to hear the merits and impact of the growing indie-Black Age. That's like only accepting a rescue from your captor.

I started down this path professionally in 1970. That was the last century! I hope it doesn't extend to the next.

The solution lays in a nexus of better business practices.....better cultural ownership on the parts of Blacks to items, services and concepts pioneered by Blacks.....and commerce. Commerce means buying......not those lame penniless "Likes" that folks think are as good as cash.

When was the last time you visited a store with a rack dedicated to indie-Black Age products, graphic novels, games & comix?

How indie-Black Age is your collection? 

Is it as Black as your music collections?

Is it as diverse as your cuisine selections? 

These are areas of massive growth potential.

 

Even my favorite wannabe Ninja-Girls agree with me on this.

On Teargas and Positive Thinking...

Posted by Reginald L. Goodwin on November 30, 2018 at 6:30am
Reuters (via HuffPost): A Honduran toddler in diapers who came to the border on the migrant caravan sobs after she and her mother fled tear gas fired by American officers at the Mexican border Sunday.

I've decided not only will there not be a "presidential pivot," but that there is no "low." When we think he's reached it, he'll just tunnel further to the center of Hades. Apparently, deviant meditations can be generated with the combination of an aggressive laxative encouraging septuagenarian elimination and early morning tweeting, a perversion of the old maxim "walking and chewing gum." The presence of his spot-on clone of Joseph Goebbels (himself a descendant of Holocaust survivors), only eggs on the most depraved behavior from our government and mimicked by a cult following of nihilists. It emboldens fascists globally: domestic terrorists here in the US, and authoritarians worldwide. What's happening at the border can't be done alone: there had to be a group of fellow citizens working in government for YEARS waiting for this moment and its orange, tweeting avatar. We have gone in two years from the world's best example (and that is arguable on many levels, I admit), to its decidedly worst.

Tear "gas" consists of either aerosolized solid compounds or evaporated liquid compounds (bromoacetone or xylyl bromide), not gas. Tear gas works by irritating mucous membranes in the eyes, nose, mouth and lungs, and causes crying, sneezing, coughing, difficulty breathing, pain in the eyes, and temporary blindness. With CS gas, symptoms of irritation typically appear after 20–60 seconds of exposure and commonly resolve within 30 minutes of leaving (or being removed from) the area. With pepper spray (also called "oleoresin capsicum", capsaicinoid or OC gas), the onset of symptoms, including loss of motor control, is almost immediate. There can be considerable variation in tolerance and response, according to the National Research Council (US) Committee on Toxicology.

Use of tear gas in warfare (as with all other chemical weapons,) is prohibited by various international treaties that most states have signed. Police and private self-defense use is not banned in the same manner. Armed forces can legally use tear gas for drills (practicing with gas masks) and for riot control. First used in 1914, xylyl bromide was a popular tearing agent since it was easily prepared. Source: Wikipedia

"The use of tear gas on children -- including infants and toddlers in diapers -- goes against evidence-based recommendations, and threatens their short and long-term health," the statement, written by AAP (American Academy of Pediatrics) President Colleen A. Kraft, reads.

"Children are uniquely vulnerable to physiological effects of chemical agents. A child's smaller size, more frequent number of breaths per minute and limited cardiovascular stress response compared to adults magnifies the harm of agents such as tear gas."

The AAP also alludes to possible psychological trauma, since children who have arrived at the border "have taken harrowing journeys."

"We must make every effort not to retraumatize them," Kraft writes. [1]

*****

Washington (CNN) President Donald Trump on Monday denied that federal agents along the US-Mexico border used tear gas on child migrants, but photos and videos show women and children migrants were among those caught up in an incident between border agents and a migrant group that rushed a border crossing Sunday.

At the White House, Trump said that border agents involved in the incident "had to use (force) because they were being rushed by some very tough people and they used tear gas."

"Here's the bottom line, nobody's coming into our country unless they're coming legally," he added. Trump also said the Mexican government "wants to see if they can straighten it out." [2]

The Trump family infrequently attended Marble Collegiate Church, on Fifth Avenue in New York City. It was chaired famously by Reverend Norman Vincent Peale, author of the "Power of Positive Thinking" and other books published along the lines of the "new thought" philosophy that would become famous in motivational books, speaking circles as well as prosperity gospel ministries, and the new age movement. Dr. Peale performed his first wedding to Ivana; his successor would perform his second to Marla Maples in the same facility. Peale would famously be derided by the psychological community as a fraud. Maybe evidenced by his choices of consigliere that was an appealing trait.

One major criticism of The Power of Positive Thinking is that the book is full of anecdotes that are hard to substantiate. Almost all of the experts and many of the testimonials that Peale quotes as supporting his philosophy are unnamed, unknown and unsourced. Examples include a "famous psychologist", a two-page letter from a "practicing physician", another "famous psychologist", a "prominent citizen of New York City", and dozens, if not hundreds, more unverifiable quotations. Similar scientific studies of questionable validity are also cited. As psychiatrist R. C. Murphy exclaimed, "All this advertising is vindicated as it were, by a strict cleaving to the side of part truth," and referred to the work and the quoted material as "implausible and woodenly pious".

A second major accusation of Peale is that he attempted to conceal that his techniques for giving the reader absolute self-confidence and deliverance from suffering are a well known form of hypnosis, and that he attempts to persuade his readers to follow his beliefs through a combination of false evidence and self-hypnosis (autosuggestion), disguised by the use of terms which may sound more benign from the reader's point of view ("techniques", "formulas", "methods", "prayers", and "prescriptions"). One author called Peale's book "The Bible of American autohypnotism". Source: Wikipedia

This is why my theory is, I don't think he "thinks" he's lying: he's - in the parlance of "faith confessions" - speaking the outcome he wants to see, a warped understanding, or an intellectual laziness not to even BOTHER to understand.

Because he said President Obama was born in Kenya, he HAD to be born in Kenya. Because he "says" the Mueller probe is a witch hunt, it HAS to be a witch hunt (that has bagged a substantial amount of Warlocks). Because he "says" there was "no collusion," their CAN'T have been any collusion. Because he "says" the children aren't harmed, they can't be harmed by teargas. Because he "says" global warming is a hoax by the Chinese, it HAS to be a hoax by the Chinese. Because he SAID their were "fine people on both sides" in Charlottesville, they have to have BEEN fine people on both sides in Charlottesville, Virginia (to remind: one side - antifascists; the other side - Nazis).

I could go on for 6,420 false claims in 649 days (9.89/day). Every prevarication uttered like a steady flow of diarrhea from an erupting sewer are all individual, cherished "golden nuggets" of truth for us mere mortals that don't understand his vibe...

Most of the saner rest of us just calls it lying.
