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.

Retired Colonel Paul Jones, US Army Staff Judge Advocate

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 (shown here) that, when exposed to sunlight, can clean itself and also actively degrade pollutants. (Image by Argonne National Laboratory.)

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.

Lithium Magic...

Drive for innovation: Electric vehicles are a major target for R&D on novel battery materials. (Image courtesy: imec)

Topics: Battery, Chemical Physics, Green Tech

The batteries we depend on for our mobile phones and computers are based on a technology that is more than a quarter-century old. Rechargeable lithium-ion (Li-ion) batteries were first introduced in 1991, and their appearance heralded a revolution in consumer electronics. From then on, we could pack enough energy in a small volume to start engineering a whole panoply of portable electronic devices – devices that have given us much more flexibility and comfort in our lives and jobs.

In recent years, Li-ion batteries have also become a staple solution in efforts to solve the interlinked conundrums of climate change and renewable energy. Increasingly, they are being used to power electric vehicles and as the principal components of home-based devices that store energy generated from renewable sources, helping to balance an increasingly diverse and smart electrical grid. The technology has improved too: over the past two and a half decades, battery experts have succeeded in making Li-ion batteries 5–10% more efficient each year, just by further optimizing the existing architecture.

Ultimately, though, getting from where we are now to a truly carbon-free economy will require better-performing batteries than today’s (or even tomorrow’s) Li-ion technology can deliver. In electric vehicles, for example, a key consideration is for batteries to be as small and lightweight as possible. Achieving that goal calls for energy densities that are much higher than the 300 Wh/kg and 800 Wh/L which are seen as the practical limits for today’s Li-ion technology. Another issue holding back the adoption of electric vehicles is cost, which is currently still around 300–200 $/kWh, although that is widely projected to go below 100 $/kWh by 2025 or even earlier. The time required to recharge a battery pack – still in the range of a few hours – will also have to come down, and as batteries move into economically critical applications such as grid storage and grid balancing, very long lifetimes (a decade or more) will become a key consideration too.

There is still some room left to improve existing Li-ion technology, but not enough to meet future requirements. Instead, the process of battery innovation needs a step change: materials-science breakthroughs, new electrode chemistries and architectures that have much higher energy densities, new electrolytes that can deliver the necessary high conductivity – all in a battery that remains safe and is long-lasting as well as economical and sustainable to produce.

Space Seed...

Note: Star Trek had an episode titled "Space Seed" with Ricardo Montalbán and his portrayal of Khan Noonien Singh. Also, since I've used Panspermia before, that was the rationale for the post title (with proper attribution, of course).

Are we truly earthlings? Is terra firma unequivocally the birthplace of humanity?

Maybe not. A new paper by a trio of Harvard University researchers argues that we all might be immigrants from deep space, brought to Earth via a mechanism called panspermia.

While the conventional wisdom from biologists has long been that life on Earth began on Earth, science fiction isn't so fuddy-duddy. “Prometheus,” Ridley Scott’s 2012 prequel to the blockbuster “Alien” franchise, is one of many films positing that our planet was seeded by extraterrestrial life.

In the movies, aliens use some sort of engineered transportation system to get here — rockets or wormholes, for example. Panspermia makes no such technical demands. Here’s the basic idea: A meteor slams into a planet where life exists, and the collision lofts into space a microbe-containing dirt clod. The clod eventually slams into another world and infects it with life.

Are germs from outer space the source of life on Earth?

"You want to be the pebble in the pond that creates the ripple for change." Tim Cook, CEO, Apple, Inc. Brainy Quote

Topics: Civics, Civil Rights, Diversity, Existentialism, Human Rights, LGBT Rights, Politics, Women's Rights

I've literally done all that I can do. I've blogged, I've called, I've text messaged, I've given money; I've reminded/nagged/begged. I've also early voted. It's now all up to you millennials tomorrow, and the futures you want for yourselves.

Trust me on this one: you will get older. You won't look as good as you do right now in the mirror. A car accident, a fall, a cancer diagnosis could change your world for the far worse than it is. I don't want you to find out the high cost of healthcare in this country (an oxymoron) and the high price of ignoring signs and "hoping it will go away on its own."

If you've decided not to have kids because of the terrible state of affairs in the world, that's fine too. I know a lot of couples that are childless by choice. Minus refugees fleeing the blow back from our country's debacles in Central America; climate change, minus clean water standards; minus standards of living: we're headed into 15 billion souls that will need food, clothing, healthcare and jobs with no ideas coming from the living fossils tied at the hip to the fossil fuels industry. They get to die before the impact of their blunders turn your golden years into a dystopian nightmare.

Think of it this way: if your "favorite" isn't on the ballot, if your candidate didn't move you to tears with their oratory; if you just think all this fuss is kind of dumb, what isn't is your futures. It's on the ballot tomorrow and every election after that.

It Can't Happen Here is a semi-satirical 1935 political novel by American author Sinclair Lewis,[1] and a 1936 play adapted from the novel by Lewis and John C. Moffitt.[2]

Published during the rise of fascism in Europe, the novel describes the rise of Berzelius "Buzz" Windrip, a demagogue who is elected President of the United States, after fomenting fear and promising drastic economic and social reforms while promoting a return to patriotism and "traditional" values. After his election, Windrip takes complete control of the government and imposes a plutocratic/totalitarian rule with the help of a ruthless paramilitary force, in the manner of Adolf Hitler and the SS. The novel's plot centers on journalist Doremus Jessup's opposition to the new regime and his subsequent struggle against it as part of a liberal rebellion. Wikipedia

I'm surprised I've not heard any parallels drawn from the plot of this novel and current events.

Like the Neanderthal nincompoop politicians lining their pockets from their 1% paymasters, I'll likely be ashes in a cemetery giving life to a maple tree (or, at least that will be my request).

I would just really appreciate a planet to supply oxygen for and clean water for my roots to drink. I tend to think you would too.

Nasty Tricks and Tasty Treats

"LaShaun, you better not be on the roof again."

"Mom, we're just up here playing Spider and Prey. We want it to look realistic."

"Hurry up and get dressed for Halloween."

"I am dressed. I am wrapped in spider-silk and Frank's going to dangle me from the roof at just the right moment."

"Did you put the lights up?"

"Yes, mom. Remote's in the kitchen."

"What's my part?"

"You don't have a part. You're the Mom handing out candy to innocent children. That is your part. You also get to be technical support. Turn on the lights after I twitch convincingly and then surprise moan."

"Frank makes his menacing hiss and the kids run off screaming into the night."

"No they won't."

"Yeah, Mom, they will. Remember when he jumped down and ran off with the Davis kid dressed as Superman?"

"All I remember is having to chase him down the street telling him not to eat that kid."

"Yeah. That's what all the kids remember too...They don't know he lives in the backyard."

"Frank says there are kids coming down the street. He's on the back side of the house."

"The camera is recording from the corner of the house and in the car."

"Great, Mom. I'm going to the roof to get ready. Stall 'em for a minute."

"Okay, Caesar Romero."

"Trust me, Mom. It's gonna be great."

"FRANK, no running off with the kids!"

"He knows, Mom. He knows."

"He knew last year, too."

"After we're done here, you have to finish packing. We'll need to be on the road by tomorrow."

"Okay, Mom. See you soon."

"Trick or Treat!"

"Hello children. What do we have here. A vampire. A princess. Captain America. What about you little girl? What are you?"

"A serial killer. They look just like everyone else."

"That's so sweet... Everyone gets some candy."

"What's that noise?"

"What noise?"

"Help me!"

Children and parents scream as LaShaun dangles from the porch awning skillfully wrapped in webs. Mom hits the lights and they see Frank, waving his arms in a menacing but completely over-acted fashion. LaShaun twitches artfully while spinning above the heads of the fleeing children.

The terrified families flee down the street, followed by smaller dog sized things swarming from around the house. Each is grabbed, webbed, scooped up and flung skyward to land with an awkward thump in the backyard of LaShaun's house.

The spiderlings too small to carry away prey, pick up every drop of candy and debris before disappearing into the darkness. It was as if no one had ever been there.

The next group of children were just a block away, everything had to be perfect.

Frank reels LaShaun in and the two high-five.

"Yes, Frank, it's going to be an all you can eat night."

MOSCOW (AP) — A security aide to Yevgeny Prigozhin, a Russian businessman who has been indicted by American investigators for allegedly trying to interfere with the 2016 U.S. election, says the mogul has been involved in attacks on several people and at least one killing, an independent Russian newspaper reported Monday.

Prigozhin has been dubbed “Putin’s chef” for organizing catering events for Russian President Vladimir Putin and even personally serving him and his guests on some occasions.

The Novaya Gazeta article Monday by reporter Denis Korotkov came out several days after unknown people sent a funeral wreath to the journalist’s home and left a basket with a severed goat’s head at the newspaper’s office.

Korotkov’s article relies on several interviews with Valery Alemchenko, a former convict who worked for Prigozhin. Alemchenko said he orchestrated attacks on Prigozhin’s opponents as well as the killing of an opposition blogger in northwest Russia, all at the mogul’s behalf.

According to the Crime Museum's web site, the third early sign of a serial killer is the mutilation of animals. Apparently in Moscow, it's a key job description.

We cherish, as well as take our freedoms for granted. If the death of Jamal Khashoggi is not investigated by the UN; if the extra judicial killings in and by Russia is not backed up with stiffer sanctions, it is a matter of time before it's tried on these shores. If the suspicious deaths of low-level bloggers or reporters are met with collective shrugs, the First Amendment will at that point in history have been fed through a shredder.

'I told you, Winston,' he said, 'that metaphysics is not your strong point. The word you are trying to think of is solipsism. But you are mistaken. This is not solipsism. Collective solipsism, if you like. But that is a different thing: in fact, the opposite thing. All this is a digression,' he added in a different tone. 'The real power, the power we have to fight for night and day, is not power over things, but over men.' He paused, and for a moment assumed again his air of a schoolmaster questioning a promising pupil: 'How does one man assert his power over another, Winston?'

Winston thought. 'By making him suffer,' he said.

'Exactly. By making him suffer. Obedience is not enough. Unless he is suffering, how can you be sure that he is obeying your will and not his own? Power is in inflicting pain and humiliation. Power is in tearing human minds to pieces and putting them together again in new shapes of your own choosing. Do you begin to see, then, what kind of world we are creating? It is the exact opposite of the stupid hedonistic Utopias that the old reformers imagined. A world of fear and treachery is torment, a world of trampling and being trampled upon, a world which will grow not less but more merciless as it refines itself. Progress in our world will be progress towards more pain. The old civilizations claimed that they were founded on love or justice. Ours is founded upon hatred. In our world there will be no emotions except fear, rage, triumph, and self-abasement. Everything else we shall destroy everything. Already we are breaking down the habits of thought which have survived from before the Revolution. We have cut the links between child and parent, and between man and man, and between man and woman. No one dares trust a wife or a child or a friend any longer. But in the future there will be no wives and no friends. Children will be taken from their mothers at birth, as one takes eggs from a hen. The sex instinct will be eradicated. Procreation will be an annual formality like the renewal of a ration card. We shall abolish the orgasm. Our neurologists are at work upon it now. There will be ...no loyalty, except loyalty towards the Party. There will be no love, except the love of Big Brother. There will be no laughter, except the laugh of triumph over a defeated enemy. There will be no art, no literature, no science. When we are omnipotent we shall have no more ..need of science. There will be no distinction between beauty and ugliness. There will be no curiosity, no enjoyment of the process of life. All competing pleasures will be destroyed. But always -- do not forget this, Winston -- always there will be the intoxication of power, constantly increasing and constantly growing subtler. Always, at every moment, there will be the thrill of victory, the sensation of trampling on an enemy who is helpless. If you want a picture of the future, imagine a boot stamping on a human face -- for ever.'

George Orwell, '1984,' Part 3, Chapter 3

*****

An obvious fan of the illegitimate president* sent pipe bombs to a specific enemies list: Joe and Jill Biden, John Brennan, Bill and Hillary Clinton, Robert De Niro, Eric Holder, Barack and Michelle Obama, Debbie Wasserman Schultz, Maxine Waters and the staple of conspiracy theorists, George Soros. They apparently threw in Governor Andrew Cuomo and CNN where his little brother works to round out the list. This is how they look mind you, when they WIN (by hook, or Russian crook). It might have something to do with vitriolic rhetoric of the media as "the enemy of the people," chants of "lock her up," praising Neo Nazis at Charlottesville and a congressman for body slamming a reporter. Just saying...

(Dishonorable mention of inciting murderous mayhem: Mama Grizzly Sarah "don't retreat, instead: RELOAD!" Palin, and Mr. Loofah Bill "Tiller the Baby Killer" O'Reilly.)

The blueprint of the dystopian by Eric Blair (George Orwell was his pen name) seems daily revealed, slowly with increasing frequency. The author hinted at any totalitarian regime that was in vogue at the time of his brief life (he died after the publication in 1949). It could be Nazis, it could be the Soviets; it could be George Lincoln Rockwell (Richard Spencer looks like he purposely cloned himself after him) in a Philip K. Dick dystopia - "The Man in the High Castle," currently in its third season on Amazon Prime. The date 1984 was merely a nod to the future. There are many theories on the origin of the novel's name. It targets no specific epoch for when a society essentially experiences entropy: it merely darkly illustrates what such a society might look like. So does "The Handmaid's Tale" by Margaret Atwood (on Hulu); "The Parable of the Sower" and "The Parable of the Talents" by Octavia Butler (that SHOULD be made into movies, or a series). Though their endings are grim, the relief for the reader is it is a complete fantasy. S/he is comforted that such an event can never happen in modern times and understanding of democratic republics, and promptly orders a soothing latte. Before the anarchy of authoritarianism, it must be fueled by apathy.

Yesterday and today [ominously, the date of the article is November 9, 2012] mark the 74th anniversary of Nazi Germany's state-instigated pogroms known as Kristallnacht (Night of Broken Glass), a turning point in Hitler's anti-Jewish policy. For most scholars, it marks the beginning of the period we now define as the Holocaust.

Nazi militants destroyed thousands of stores and Jewish homes, desecrated cemeteries and burned down hundreds of synagogues. German Jewish citizens were arrested, systematically humiliated and abused in public in every city, town and village of Germany and in the recently annexed Austria. The majority of German citizens were bystanders to the pogrom and did not try to prevent the vandalism and destruction.

The events of Kristallnacht teach a valuable lesson. They show that a modern society can become numbed to the fate of its minorities. Since Hitler's rise to power in March 1933, Jews had been classified and categorized as "others." They were demonized, legally discriminated against and spatially segregated. Non-Jewish Germans were increasingly convinced that the treatment of Jews was justified and did not concern them. Remembering Kristallnacht: It starts with apathy, Alejandro Baer, Star Tribune

I will make this my last post before November 5 and 6, 2018 (literally: Judgment Day). Our country will either be a referendum against creeping fascism, or an endorsement of it. Putin has boldly proclaimed our better days are behind us, mocking the United States and orange shit stain to John Bolton's face. The KGB master spy's ideal is likely a return to serfdom on a global scale, with figurehead potentates reporting into him as kingpin crime boss, the "strongmen" maintaining control with fear, division and xenophobia. William Shakespeare said "what's past is prologue," and since the future is ours to shape, it doesn't have to be an inevitable slide to tyranny. This is a time to early vote, then canvas; then call until the last minute - until the last breath. This is the election of not just our lifetimes, but the lifetimes of our posterity yet born, for a world they'll inherit that will be habitable, or not; a world that will be fairer to people of color, our daughters, our LGBT relatives, immigrants... or, not. We've all lived through the low turnouts of the 1994 and 2014 midterms, near and distant history that have shaped this current crisis now. This is NOT a time for the indifferent, haughty bench warmers or the "too woke" to vote. The apathetic need to get out of the way of The Indivisible. If we lose this one, we all lose a nation and our place as the world's last, best hope.

Those remaining in that dark aftermath of a dangerous, unsure world are usually ordered about the remainder of their short days by zombies, Nazis...or, ghouls.

Shrink Ray...

Using a new kind of "shrink ray", UT Austin scientists can alter the surface of a hydrogel pad in real time, creating grooves (blue) and other patterns without disturbing living cells, such as this fibroblast cell (red) that models the behavior of human skin cells. Rapid appearance of such surface features during cell growth can mimic the dynamic conditions experienced during development and repair of tissue (e.g., in wound healing and nerve regrowth).

From "Fantastic Voyage" to "Despicable Me," shrink rays have been a science-fiction staple on screen. Now chemists at The University of Texas at Austin have developed a real shrink ray that can change the size and shape of a block of gel-like material while human or bacterial cells grow on it. This new tool holds promise for biomedical researchers, including those seeking to shed light on how to grow replacement tissues and organs for implants.

"To understand, and in the future engineer, the way that cells respond to the physical properties of their environment, you want to have materials that are dynamically re-shapeable," said Jason B. Shear, professor of chemistry and co-inventor of the new tool.

The work was published online today in the Journal of the American Chemical Society.

The real power of shrinking the material used to grow cells—called the substrate—isn't so much in making it smaller as it is in selectively changing the shape and texture of the surface. By controlling precisely which parts of the interior of the material shrink, the researchers can create specific 3-D features on the surface including bumps, grooves and rings. It's like pinching a rug from below to form peaks and valleys on the surface.

The researchers can also change the location and shapes of surface features as time goes by, for example turning a mountain into a molehill or even a sinkhole, mimicking the dynamic nature of the environment in which cells typically live, grow and move.

The shrink ray is a near-infrared laser that can be focused onto tiny points inside the substrate. The substrate looks and behaves a bit like a block of Jell-O. On the microscopic level, it's made of proteins jumbled and intertwined like a pile of yarn. When the laser strikes a point within the substrate, new chemical bonds are formed between the proteins, drawing them in more tightly, a change that also alters the surface shape as it's tugged on from below. Researchers scan the laser through a series of points within the substrate to create any desired surface contour at any place in relation to targeted cells.

Unlike other methods for altering the substrate under living cells, the UT Austin shrink ray doesn't heat or chemically alter the surface, damage living cells or cause cells to unstick from the surface. And it allows the formation of any 3-D pattern on demand while viewing the growing cells through a microscope.

Post Mole Day...

Topics: Chemistry, Education, NIST, Periodic Table, STEM

In suburban Maryland, on the third floor of the Advanced Chemical Sciences Laboratory at the National Institute of Standards and Technology (NIST), Bob Vocke and Savelas Rabb are explaining how they are helping to redefine the mole, that mammoth concept we learned in high-school science class.

Mostly, this means using abstract symbols and numbers, dancing along in a long equation that Vocke obviously thinks is beautiful. You can tell because he enthusiastically writes each detail out on the white board for some lab visitors. Every so often, Rabb provides suggestions or tells a joke and sort of eggs Vocke on. It is clear they are having a good time and could do this kind of annotation and explanation all day.

After the mole equation, they add more:

To fully grasp the new definition of the mole, you must embrace these long equations, which show how that measurement connects to fundamental constants of the universe—such as the speed of light in vacuum and the amount of charge in an electron. In turn, these fundamental constants will completely redefine the modern metric system, known as the International System of Units (SI). The mole is one of the seven base units of the SI.

For Vocke and Rabb, the equation work brings joy. The process is entertaining, and a little fun.

For most others, it seems impossibly cryptic.

On the surface, the mole’s basic definition will remain the same. It’s a measure of stuff—how many molecules or atoms you have of a particular substance such as water, or gold or a protein.

But the current definition is more complicated than it needs to be. In the present metric system, a mole is the amount of substance that contains as many elementary entities as there are atoms in 0.012 kilograms of the most common form of carbon, known as carbon-12. A further complication: the mole relies on another definition, the definition of the kilogram, which is currently specified by the mass of a platinum-iridium cylinder locked up in a special vault outside Paris, France.

Mole Day is an unofficial holiday celebrated among chemists, chemistry students and chemistry enthusiasts on October 23, between 6:02 a.m. and 6:02 p.m.,[1][2] making the date 6:02 10/23 in the American style of writing dates. The time and date are derived from Avogadro's number, which is approximately 6.02 × 1023, defining the number of particles (atoms or molecules) in one mole (mol) of substance, one of the seven base SI units.

Mole Day originated in an article in The Science Teacher in the early 1980s. Inspired by this article, Maurice Oehler, now a retired high school chemistry teacher from Prairie du Chien, Wisconsin, founded the National Mole Day Foundation (NMDF) on May 15, 1991. Wikipedia

Nouveau Paradox...

Topics: Modern Physics, Quantum Mechanics, Schrödinger's Cat, Theoretical Physics

In the world’s most famous thought experiment, physicist Erwin Schrödinger described how a cat in a box could be in an uncertain predicament. The peculiar rules of quantum theory meant that it could be both dead and alive, until the box was opened and the cat’s state measured. Now, two physicists have devised a modern version of the paradox by replacing the cat with a physicist doing experiments—with shocking implications.

Quantum theory has a long history of thought experiments, and in most cases these are used to point to weaknesses in various interpretations of quantum mechanics. But the latest version, which involves multiple players, is unusual: it shows that if the standard interpretation of quantum mechanics is correct, then different experimenters can reach opposite conclusions about what the physicist in the box has measured. This means that quantum theory contradicts itself.

The conceptual experiment has been debated with gusto in physics circles for more than two years—and has left most researchers stumped, even in a field accustomed to weird concepts. “I think this is a whole new level of weirdness,” says Matthew Leifer, a theoretical physicist at Chapman University in Orange, California.

The authors, Daniela Frauchiger and Renato Renner of the Swiss Federal Institute of Technology (ETH) in Zurich, posted their first version of the argument online in April 2016. The final paper appears in Nature Communications on 18 September. (Frauchiger has now left academia.)

Tools Made of Light...

Topics: Diversity in Science, Optical Tweezers, Laser, Nobel Prize, Women in Science

I'm pretty sure I was in the throw of midterms. I did not miss it, just didn't have time to post about it.

Tools made of light

The inventions being honored this year have revolutionized laser physics. Extremely small objects and incredibly rapid processes are now being seen in a new light. Advanced precision instruments are opening up unexplored areas of research and a multitude of industrial and medical applications.

Arthur Ashkin invented optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers. This new tool allowed Ashkin to realise an old dream of science fiction – using the radiation pressure of light to move physical objects. He succeeded in getting laser light to push small particles towards the centre of the beam and to hold them there. Optical tweezers had been invented.

A major breakthrough came in 1987, when Ashkin used the tweezers to capture living bacteria without harming them. He immediately began studying biological systems and optical tweezers are now widely used to investigate the machinery of life.

Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses ever created by mankind. Their revolutionary article was published in 1985 and was the foundation of Strickland’s doctoral thesis.

Dear Millennials,

New York Magazine (the home state of our current orange nightmare) couldn't be more stark: your futures are being determined by ossified, geriatric creatures that KNOW they will not live to see the impact of their disastrous decisions on the environment, stoking wars, cutting taxes for their wealthy benefactors and themselves (ballooning the federal deficit); packing the Supreme Court with right wing, misogynist and sexist ideologues that don't hold your views on fairness, equality and will influence your lives for at least two generations. Along with subverting our electoral process in 2016 with Russia, the cover up of the apparent murder and brutal dismemberment of Jamal Khashoggi (15 must be the "magic number" in Saudi Arabia). This may tie to Jared Kushner being in the Saudi prince's "pocket," usually meaning he owes him, likely for a business loan that salvaged his New York property, ominously addressed "666 Fifth Avenue." Whether agnostics, atheists or theists, that's a lot to digest. I list these concerns because you will only get older, and the world they're destroying you will inherit, in whatever condition it's left in, however long it lasts.

Notice the message is fear: I saw a commercial warning of socialism, open borders, MS-13 paid for by a conservative PAC. I saw a bus load of seniors in Georgia getting on a bus to vote being stopped for no crime other than voting. Native Americans in North Dakota are having their votes blocked by legal fiat. Note the distinct dichotomy in the definitions of democracy and fascism - they're obviously leaning towards the latter. Parkland shooting survivors and their activism terrifies them. Since 2015, it's been observed they are getting older and dying off. The heady days of Ronald Reagan taking 61 to 30 voters between 18 to 24 is well-past their better days and jump shots. A lot of things back then aligned with that popularity: nostalgia was "Laverne and Shirley"; "Happy Days" "Back to the Future" and "Family Ties" with Michael J. Fox as a young urban professional - conservatism was "cool" but it's overstayed its shelf life. Democracy only worked for them when they were in the numerical majority - the tables turn circa 2042, and by the blatantly demonstrable voter suppression activities WITHIN the United States, they're panicking early now. The ONLY way they can stay in power is to suppress the youth and minority vote, and maybe collude with a foreign power.

Speaking of the environment: we're losing insects around the world at an alarming rate due to climate change. The meddlesome critters are an important part of our food chain, which if you're capable of reading this post, you're squarely at the top of it. Destroy the foundation; it eventually drives up the price of food, then inhibits the access to it. That is a recipe for starvation, poverty, hyper income inequality, wars...and extinction.

The capitalized term First Contact, in Human context, was used to specifically refer to the first official publicly and globally known contact between Humans and extraterrestrials. The First Contact took place on the evening of April 5, 2063, when a Vulcan survey ship, the T'Plana-Hath, having detected the warp signature of the Phoenix, touched down in Bozeman, central Montana, where they met with the Phoenix's designer and pilot, Zefram Cochrane. This event was generally referred to as the defining moment in Human history, eventually paving the way for a unified world government and, later, the United Federation of Planets. The event also became an annual holiday called First Contact Day. Memory Alpha - First Contact

I've always been dubious about this platitude in Trek mythology, that somehow knowing that we're "not alone" in the universe was some kind of unifying force multiplier to eternal (and secular) Kumbaya and Koinonia. The screaming at immigrant children at the border BEFORE the 2016 elections and kiddie concentration camps now leave my optimism in doubt. Roddenberry was playfully imaginative, but Pollyannish at best.

Star Trek was born in the 1960s as was the Civil Rights movement, which involved hoses, bricks, fire bombings and assassinations. It was during the Cold War with (ironically) Russia, and the notion that "duck and cover" drills wouldn't ultimately save us from extinction. So, it was a brief respite from the existentialism that gripped most in those days. Someone who looked like us might survive our own pride and hubris. There could be life after half-life.

The belief that everything in the universe is part of the same fundamental whole exists throughout many cultures and philosophical, religious, spiritual, and scientific traditions, as captured by the phrase 'all that is.' The Nobel winner Erwin Schrödinger once observed that quantum physics is compatible with the notion that there is indeed a basic oneness of the universe. Therefore, despite it seeming as though the world is full of many divisions, many people throughout the course of human history and even today truly believe that individual things are part of some fundamental entity.

People who believe that everything is fundamentally one differ in crucial ways from those who do not. In general, those who hold a belief in oneness have a more inclusive identity that reflects their sense of connection with other people, nonhuman animals, and aspects of nature that are all thought to be part of the same "one thing." This has some rather broad implications.

First, this finding is relevant to our current fractured political landscape. It is very interesting that those who reported a greater belief in oneness were also more likely to regard other people like members of their own group and to identify with all of humanity. There is an abundance of identity politics these days, with people believing that their own ideology is the best one, and a belief that those who disagree with one's own ideology are evil or somehow less than human.

It might be beneficial for people all across the political spectrum to recognize and hold in mind a belief in oneness even as they are asserting their values and political beliefs. Only having "compassion" for those who are in your in-group, and vilifying or even becoming violent toward those who you perceive as the out-group, is not only antithetical to world peace more broadly, but is also counter-productive to political progress that advances the greater good of all humans on this planet.

Quaint, and for a better time, but until we get there...

"What the heck does Mom want? Oh, Mom probably doesn't understand the time difference, she's in Dallas right now and is probably still thinking it's California time…maybe she just wants me to go check on her cats…" A litany of mundane explanations ran through James Bailey's bleary mind at 3:23 a.m. on October 3 when he was awakened from a deep sleep by three phone calls from his mother's cell number. Bailey silenced his phone for the first two, getting grumpier with each ring. Call #3 did the trick. He picked up the phone and said groggily, "What do you want?" With great excitement and maybe a tinge of impatience, his mother said, "I wish you had picked up your phone, but I just won the Nobel Prize."

Bailey bolted upright, thrilled by the news and fueled by adrenaline. "I was overjoyed for her. It's fairly difficult to verbalize how I feel," he said. He never did manage to go back to sleep that night. In a few hours, he'd be able to share the news with his colleagues when he arrived at his job at NASA's Jet Propulsion Laboratory in Building 179, High Bay 1 -- the clean room where he is a flight technician working on Mars 2020.

Bailey's mother is Frances Arnold, the Linus Pauling Professor of Chemical Engineering at Caltech, which manages JPL for NASA. Her 2018 Nobel Prize in Chemistry honors her pioneering work in creating new, improved enzymes in the laboratory using the principles of evolution. Arnold shares the prize with two other scientists.

Arnold's bio has an abundance of academic milestones and stellar awards. She was the first woman to receive the 2011 Charles Stark Draper Prize from the National Academy of Engineering. She is also the first woman and one of just a few individuals elected to all three branches of the National Academies: for Medicine, Sciences and Engineering.

Bailey traveled a different path than his mother to his job at JPL. Growing up in Pasadena, he didn't thrive in conventional schools, so he pursued vocational training in welding and machining. After high school, he worked on high-performance cars at a local shop. At 20, he joined the Army, where he was trained as a Blackhawk helicopter mechanic and became part of a flight crew. After wrapping up six years of military service, including crucial work on medical evacuation helicopter teams in Afghanistan, he learned JPL was looking for people with an aviation background to work as flight technicians. Bailey fit the bill, and he was hired.

AI and MEMS...

A single silicon beam (red), along with its drive (yellow) and readout (green and blue) electrodes, implements a MEMS capable of nontrivial computations.

In order to achieve the edge computing that people talk about in a host of applications including 5G networks and the Internet of Things (IoT), you need to pack a lot of processing power into comparatively small devices.

The way forward for that idea will be to leverage artificial intelligence (AI) computing techniques—for so-called AI at the edge. While some are concerned about how technologists will tackle AI for applications beyond traditional computing—and some are wringing their hands over which country will have the upper hand in this new frontier—the technology is still pretty early in its development cycle.

Nano Noise...

New noise: researchers have discovered a new type of noise that is associated with differences in temperature. (Courtesy: iStock/Swillklitch)

A new type of electronic noise has been discovered by a team of physicists and chemists in Israel and Canada. Dubbed “delta-T noise”, the effect occurs when two sides of a tiny electrical junction are at held at different temperatures. As electronic devices become ever smaller, the researchers predict that delta-T noise could become increasingly problematic. The good news is that delta-T noise could be used to measure temperature differences in nanometer-scale objects – something that is extremely difficult to do.

When physicists think of noise it is not the clamor from a pop concert or a busy road, but rather electrical signals that are an intrinsic property of a device. For almost 100 years, physicists have known about two sorts of fundamental noise in electrical signals. Thermal noise is proportional to temperature and is a result of the random motion of electrons. This creates fluctuations in electrical current even if there is no applied voltage and the average current is zero. Thermal noise can have negative consequences in a circuit, but it can also be used to measure the absolute temperature of an object. The second type of noise is called shot noise and does require an applied voltage. Shot noise occurs at very low currents when the discrete nature of electrons causes fluctuations in current.

The idea of delta-T noise first came to Oren Tal of the Weizmann Institute of Science when he was studying the effect of thermal noise on a molecular junction. The junction comprised a single molecule between two electrodes, which were at different temperatures. He realized that in addition to thermal noise, there may also be a noise associated with the temperature difference.

Moon Moons...

Could Earth's moon have its own moon? Science says: in theory. Credit: NASA/JPL/Space Science Institute

I couldn't compound the two words in the post title (as in the article) and keep a straight face. Although, someone will likely write fiction about double system moons (if they haven't already).

True to form, the Internet has endeavored to name an unnamed thing, and the results are hilarious. From the people who brought you Boaty McBoatface— the Arctic research drone that has already returned some very interesting discoveries from the world's coldest abysses — here come moonmoons: moons that orbit other moons.

Moonmoons — also known online as submoons, moonitos, grandmoons, moonettes and moooons — may not exist in our solar system or any other. However, according to a pair of astronomers writing in the preprint journal arXiv.org earlier this week, the concept of a moon hosting its own mini-moon is, at least, plausible.

Abstract
Each of the giant planets within the Solar System has large moons but none of these moons have their own moons (which we call submoons). By analogy with studies of moons around short-period exoplanets, we investigate the dynamical stability of submoons. We find that 10 km-scale submoons can only survive around large (1000 km-scale) moons on wide-separation orbits. Tidal dissipation destabilizes the orbits of submoons around moons that are small or too close to their host planet; this is the case for most of the Solar System’s moons. A handful of known moons are, however, capable of hosting long-lived submoons: Saturn’s moons Titan and Iapetus, Jupiter’s moon Callisto, and Earth’s Moon. Based on its inferred mass and orbital separation, the newly-discovered exomoon candidate Kepler-1625b-I can, in principle, host submoons, although its large orbital inclination may pose a difficulty for dynamical stability. The existence, or lack thereof, of submoons, may yield important constraints on satellite formation and evolution in planetary systems.
