"Locks are made for honest people."

Robert H. Goodwin, June 19, 1925 - August 26, 1999 ("Pop")

It is indisputable that technology is now a fundamental and inextricable part of our everyday existence—for most people, our employment, transportation, healthcare, education, and other quality of life measures are fully reliant on technology. Our dependence has created an urgent need for dynamic cybersecurity that protects U.S. government, research and industry assets in the face of technology advances and ever more sophisticated adversaries.

The U.S. Department of Energy’s (DOE) Argonne National Laboratory is helping lead the way in researching and developing proactive cybersecurity, including measures that leverage machine learning, to help protect data and critical infrastructure from cyberattacks.

Machine learning is a category of artificial intelligence that involves training machines to continually learn from and identify patterns in data sets.

“Applying machine learning approaches to cybersecurity efforts makes sense due to the large amount of data involved,” said Nate Evans, program lead for cybersecurity research in the Strategic Security Sciences (SSS) Division. ​“It is not efficient for humans to mine data for these patterns using traditional algorithms.”

Argonne computer scientists develop machine learning algorithms using large data sets— comprising log data from different devices, network traffic information, and instances of malicious behavior—that enable the algorithms to recognize specific patterns of events that lead to attacks. When such patterns are identified, a response team investigates instances matching those patterns.

Following an attack, the response team patches the vulnerability in the laboratory’s intrusion protection systems. Forensic analysis can then lead to changes that prevent similar future attacks.

“We are looking for ways to stop attacks before they happen,” said Evans. ​“We’re not only concerned with protecting our own lab, we’re also developing methods to protect other national labs, and the country as a whole, from potential cyberattacks.”

The Democratic Leadership Council (DLC) was a non-profit 501(c)(4) corporation[1] founded in 1985 that, upon its formation, argued the United States Democratic Party should shift away from the leftward turn it took in the late 1960s, 1970s, and 1980s. One of its main purposes was to win back white middle class voters with ideas that addressed their concerns.[2] The DLC hailed President Bill Clinton as proof of the viability of Third Way politicians and as a DLC success story.

The DLC's affiliated think tank was the Progressive Policy Institute. Democrats who adhered to the DLC's philosophy often called themselves New Democrats. This term is also used by other groups who have similar views on where the party should go in the future, like NDN[3] and Third Way.[4]

On February 7, 2011, Politico reported that the DLC would dissolve, and would do so as early as the following week.[5] On July 5 of that year, DLC founder Al From announced in a statement on the organization's website that the historical records of the DLC have been purchased by the Clinton Foundation.[6] The DLC's last chairman was former Representative Harold Ford of Tennessee, and its vice chair was Senator Thomas R. Carper of Delaware. Its CEO was Bruce Reed.

The Supreme Court's 2010 decision in Citizens United v. Federal Election Commission helped unleash unprecedented amounts of outside spending in the 2010 and 2012 election cycles. The case, along with other legal developments, spawned the creation of super PACs, which can accept unlimited contributions from corporate and union treasuries, as well as from individuals; these groups spent more than $800 million in the 2012 election cycle. It also triggered a boom in political activity by tax-exempt "dark money" organizations that don't have to disclose their donors. You can listen to the decision (see "Opinion Announcement - January 21, 2010") as read by Justice Kennedy and the dissenting opinion read by Justice Stevens. Read on to learn more about how the Supreme Court transformed the campaign finance landscape with this decision, and how it is now affecting U.S. politics.

Citizen's United vs. Federal Election Commission, OpenSecrets.org

Both political parties through the need for funds deified the "free hand of the market." Both are concerned at the resonant chord Sanders, Warren et al have struck with an electorate not umbilical-tied to the Dow Jones Industrial Average. Instead of a "rising tide that lifts all boats," the effort to kowtow at Moloch's altar has produced Caligula.

Former Governor and "Bain Capitalist" Deval Patrick threw his hat into the democratic primary, as did billionaire and former republican, former independent and ended-up-democrat Mayor Mike "stop and frisk" Bloomberg. Governor Patrick seemed to eclipse the news another school shooting occurred in California, now apparently routine, despite the death of two citizens that won't grow up. Meanwhile, Erdoğan blasted a propaganda video over his I-Pad showing the Kurds as terrorists, the same aforementioned Kurds he apparently has a "great relationship" with while committing genocide.

In the ever-changing defense of the indefensible, the Reich Wing has veered from the impeachment inquiry hearings have "no pizzazz" and chief of lies tweeting about it sixty times in a day, Hillary colluded with the Russians (to apparently, lose the election and plunge us all into a dystopian nightmare); crowd strike, star chamber, no Quid Pro Quo, a Quid but no Pro Quo what-about-ism on bribery and the latest hilarious defense: he's too stupid to commit a genuine Mafia shakedown - he forgot the cement boots.

We have a political party that believes in science, facts and reality who's name has been turned into a pejorative ("democrat party").

We have a political party that believes in conspiracy theory, lies and obfuscation; "creates its own Karl Rove realities," believes the self-admitted sexual assaulter NEVER LIES (according to Franklin Graham) that somehow with a straight face still associates itself with integrity, principles and "family values." Stephen Miller - the architect of our kiddie concentration camps, apparently willed himself "white" and shared racist propaganda that would have prevented his grandfather's escape from Polish pogroms.

Impeachment, despite the protestation is in The Constitution. Alexander Hamilton (well pre the Broadway hit and triple platinum album) wrote about it in the Federalists Papers:

A well-constituted court for the trial of impeachments is an object not more to be desired than difficult to be obtained in a government wholly elective. The subjects of its jurisdiction are those offenses which proceed from the misconduct of public men, or, in other words, from the abuse or violation of some public trust. They are of a nature which may with peculiar propriety be denominated POLITICAL, as they relate chiefly to injuries done immediately to the society itself. The prosecution of them, for this reason, will seldom fail to agitate the passions of the whole community, and to divide it into parties more or less friendly or inimical to the accused. In many cases it will connect itself with the pre-existing factions, and will enlist all their animosities, partialities, influence, and interest on one side or on the other; and in such cases there will always be the greatest danger that the decision will be regulated more by the comparative strength of parties, than by the real demonstrations of innocence or guilt. Federalist 65, Yale Law School

The President of the United States would be liable to be impeached, tried, and, upon conviction of treason, bribery, or other high crimes or misdemeanors, removed from office; and would afterwards be liable to prosecution and punishment in the ordinary course of law. The person of the king of Great Britain is sacred and inviolable; there is no constitutional tribunal to which he is amenable; no punishment to which he can be subjected without involving the crisis of a national revolution. In this delicate and important circumstance of personal responsibility, the President of Confederated America would stand upon no better ground than a governor of New York, and upon worse ground than the governors of Maryland and Delaware. Federalist 69, Yale Law School

Putin would love to discredit representative democracy, itself a pejorative to him. The Internet Research Agency has interfered in elections around the globe, an annoyance so far with one clear success here in the US. He would love for all nations to organize around strongmen - reporting to him, of course - making him richer than Midas and Solomon.

For the rest of us, outside of the politburo would be literally as Russia faced years before its 1989 fall: disease, famine and death.

The defeat and demise of democracy would have the impact of the Chicxulub crater.

Except instead of a wall falling symbolically, we could be facing extinction. Only delusion and hubris would make us ignore this.

A few xenophobic Ayn Rand worshipers will be rich beyond the wildest psychopaths' dreams - for a moment - until inevitable Entropy completes our societal and mass species apoptosis. There will be no second act and fully negates starships, lest they be filled with ghosts, corpses and dreams. It's that stark.

Slowly but surely, the surface of Saturn’s strange moon Titan is being revealed. Researchers have made the first map of the geology of Titan’s entire surface, and it will eventually help us figure out what the climate is like there.

Titan’s atmosphere is full of a thick, orange haze that blocks visible light from reaching the surface, making it difficult for spacecraft to take pictures. NASA’s Cassini spacecraft, which orbited Saturn from 2004 to 2017, took radar and infrared data of Titan’s surface, giving researchers a hint of the terrain below.

Rosaly Lopes at NASA’s Jet Propulsion Laboratory in California and her colleagues assembled those observations and placed each area, or unit, into one of six categories: lakes, craters, dunes, plains, hummocky terrain – meaning hills and mountains – and labyrinth, which looks like heavily eroded plateaus. They then made a map of where each of those terrains exists on Titan’s surface.

The researchers likely watched a lot of Saturday morning cartoons in the 1980s: original intro.

(CAMBRIDGE, Mass.) — The majority of soft robots today rely on external power and control, keeping them tethered to off-board systems or rigged with hard components. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Caltech have developed soft robotic systems, inspired by origami, that can move and change shape in response to external stimuli, paving the way for fully untethered soft robots.

The research is published in Science Robotics.

"Extraordinary claims require extraordinary evidence." Carl Sagan

I'm guessing "I did Ancestry" is going to become the "I used to do Amway" in the 21st Century?

I participated, thinking it was legitimate science. It did somewhat jive with my own experiences of being consistently identified by Nigerians as resembling someone from the Igbo. This again is pure conjecture, and likely only a polite guess.
 

I can see the desire to know about our roots, especially if you're a part of the African Diaspora is tempting as well as an opportunity for confidence rackets and quackery.

In the spring of 2017, a college student named Mary spit into a tube and sent it to the DNA testing company Ancestry, which analyzed it and sent back a breakdown of her family history.

But Mary wanted to know more. The human genome contains, in theory, an extraordinary wealth of pre-programmed information about who we are and who we might become: whether she was at risk for the same types of cancer that killed her parents, for instance, or if she had medical conditions she could unknowingly pass on to her children.

For that information, Mary — we’re withholding her last name to protect her privacy — turned to a dubious new sector of the genomics industry, in which startups claim to provide vastly greater insights than prominent companies like Ancestry and 23andMe do. She uploaded a copy of her raw genetic code, which Ancestry provided as a 17.6 megabyte text file, to a site called Genomelink, which advertises tests for everything from medical conditions and mental illnesses to ludicrously specific personality traits including “loneliness,” “social communication problems,” and “vulnerability to helicopter parenting.”

But when her results arrived, Mary immediately noticed that many were “wildly inaccurate.” Genomelink said she was “less easily depressed,” but Mary was diagnosed with clinical depression at a young age. The startup predicted that she had a peanut allergy, but Mary told Futurism that “peanut butter is one of the true loves of my life.” Other errors in Mary’s report included traits like blood iron levels, body fat measurements, hearing problems, height, and skin complexion.

“I felt that much of it was off-base and unhelpful,” she told Futurism, “as it didn’t fit me at all.”

Genomelink is just one of a growing number of shady DNA testing startups now operating in the regulatory Wild West of commercial genomics.

There’s GenePlaza, for instance, which sold a DNA test that claimed to predict users’ sexual preferences — and still sells tests that purport to measure intelligence and risk of depression. A company called Soccer Genomics claims to examine a child’s DNA to create a sports training regimen to turn them into the perfect soccer player. An outfit called GenoPalate told a Milwaukee Journal Sentinel reporter that their DNA demanded a diet of elk meat and passion fruit. A venture called Vinome claims it can recommend the perfect wine for each person based on their genetic code.

The problem, according to experts, is that these companies are promising information about DNA with a granularity that even scientists can’t deliver. Deanna Church, a geneticist at the biotech company Inscripta, told Futurism the tests are “all equally useless.”

“There is not a scientific basis for this sort of testing,” she said. “I certainly would not recommend anyone spend any money on this sort of thing.”

TAMPA — From the convention stage here, the Republican Party has tried to highlight its diversity, giving prime speaking slots to Latinos and blacks who have emphasized their party’s economic appeal to all Americans.

But they have delivered those speeches to a convention hall filled overwhelmingly with white faces, an awkward contrast that has been made more uncomfortable this week by a series of racial headaches that have intruded on the party’s efforts to project a new level of inclusiveness.

The tensions come amid a debate within the GOP on how best to lure new voters. The nation’s shifting demographics have caused some Republican leaders to worry not only about the party’s future but about winning in November, particularly in key swing states such as Virginia and Nevada.

The demographics race we’re losing badly,” said Sen. Lindsey O. Graham (S.C.). “We’re not generating enough angry white guys to stay in business for the long term.”

Rosalind S. Helderman and Jon Cohen, Washington Post, August 29, 2012

Republican National Conventions are paste-white affairs with a smattering of African American members and some tokens as room jewelry. That has declined steadily since 2000. The GOP Autopsy Report is a fascinating document, and could have stopped the bleeding had it not been turned to toilet paper by our current Russian ass(et). 

Two weeks ago, I posted excerpts from the New Republic article by Jeet Heer: The Right Is Giving Up on Democracy. Disrupting the congressional process of inquiry is a departure from the governing norms of democracy itself.

In the summer of 2015, the House Select Committee on Benghazi was still chasing conspiracy theories, holding a series of closed-door hearings with officials and witnesses. As part of the investigatory process, other members of Congress who were interested in learning more were excluded – and when former House Oversight Committee Chairman Darrell Issa (R-Calif.) tried to crash a deposition, Rep. Trey Gowdy (R-S.C.) blocked him.

On this, Gowdy, who chaired the Benghazi panel, was correct. Not only did he take steps to prevent a political circus – nearly every witness was interviewed behind closed doors – but House rules only permit members to participate in depositions if they serve on the relevant committees. These are not spectator events.

SCIF: Sensitive Compartmented Information Facility. A Sensitive Compartmented Information Facility (SCIF; pronounced "skiff"), in British and United States military, national security/national defense and intelligence parlance, is an enclosed area within a building that is used to process Sensitive Compartmented Information (SCI) types of classified information. Wikipedia

This WASP-C (White Anglo Saxon Protestant, Cisgender) frat boy stunt has compromised our SCIF.

This is the SAME SCIF the Benghazi Hearings were held in.

Forty-five republicans are literally IN the room with full access to the same classified information and testimony being investigated. Like a Grand Jury, this part of the process is not public. It will eventually be aired publicly.

This is the SAME SCIF entered with cell phones that can be hacked by distant actors in far off countries (like Russia) that can get an electronic "peek" into the building. It probably happened while ordering pizza. It only takes one. The hearing was delayed likely to allow NSA to sweep and re-secure the SCIF. It violates federal law.

I hope it's not permanently compromised, as Putin would want it. I called my representative and blasted him through his admin for a sophomoric stunt.

President Teddy Roosevelt (R) offered educator Booker T. Washington a visit to the Presidential Mansion that proved contentious to a nation based on the "norms' of white supremacy. African Americans weren't official "guests," they were at most servants and nothing more. It is said after that visit, the mansion would get the definitive name "White House," removing all doubt about the nation's foundations.

"The Southern Strategy" is suffering from Entropy. It worked well in 1968, exacerbating the fears of "the other" by white southern Dixiecrats that stormed out of the Democratic Party post Brown vs. Board of Education (1954), The Civil Rights Act (1964), the Voting Rights Act (1965); the Fair Housing Act (1968). Forty years later, they would collectively lose their minds with the election of the one and only African American to the highest office on the planet. He would move his family into a house built by slaves, the descendants servants for generations and still there. He would be hung in effigy and disparaged in vitriol. The report of the demographics shift in the nation - "demographics is destiny" (Auguste Comte) - cemented the collective conniption fit of the white and privileged.

“We’ve got a queer running for president, if that ain’t about as ugly as you can get,” Sevier County Commissioner Warren Hurst said to the crowd after telling them to “wake up.”

“I’m not prejudiced, but by golly,” continued Hurst, waving his finger in the air, “a white male in this country has very few rights, and they’re getting took more every day.” While one member of the crowd walked out in protest, Hurst was met with whistles and applause from the audience after he finished speaking.

We’re not generating enough angry white guys to stay in business for the long term.”

Nixon on his reelection swept the south - the first time by a republican - but, this isn't 1968. Or 1980 - 1988. The wink-and-nod genteel "soft bigotry of low expectations" under the current darkness of this Orange Satan went from dog whistle to foghorn.

This was and is about those in power that don't want that power interrupted, by people of color, women, LGBT, immigrants et al.

And they're likely willing to burn the whole joint down to "make America [a] great (white supremacists' hope) again."

Twisted Fridge...

Topics: Applied Physics, Green Tech, Research, Thermodynamics


A new refrigeration technology based on the twisting and untwisting of fibers has been demonstrated by a team led by Zunfeng Liu at Nankai University in China and Ray Baughman at the University of Texas at Dallas in the US. As the demand for refrigeration expands worldwide, their work could lead to the development of new cooling systems that do not employ gases that are harmful to the environment.

The cooling system relies on the fact that some materials undergo significant changes in entropy when deformed. As far back as 1805 – when the concepts of thermodynamics were first being developed – it was known that ordinary rubber heats up when stretched and cools down when relaxed. In principle, such mechanocaloric materials could be used in place of the gases that change entropy when compressed and expanded in commercial refrigeration systems. Replacing gas-based systems is an important environmental goal because gaseous refrigerants tend to degrade the ozone layer and are powerful greenhouse gases.

In their experiments, Liu and Baughman’s team studied the cooling effects of twist and stretch changes in twisted, coiled and supercoiled fibers of natural rubber, nickel-titanium and polyethylene fishing line. In each material, they observed a surface cooling as high as 16.4 °C, 20.8 °C, and 5.1 °C respectively, which they achieved through techniques including simultaneous releases of twisting and stretching, and unraveling bundles of multiple wires.

As stated, my incarceration ends this Friday. However, my "due process" is as much a mystery as my apparent offense. Any appeals goes into the nether ether; a 1 and 0 equivalent of a digital black hole. The temporary suspension of my First Amendment rights is annoying, but I have the ability to post to forums that I'm the administrator, and if determined to, I can message any post to another Facebook subscriber "on the outside" to post for me. The inconvenience comes when you wish to join into a flow of ideas over something you have an emotional tie to (like, homecoming). As a parent and now a grandparent, I can attest it is far more instructive "teaching a lesson" when the offender has a clear explanation of what the original offense was. I likely ran afoul of an algorithm.

It's interesting that Facebook is the byproduct of a theft if "The Social Network" is to be believed. To address its (assumed) accidental complicity in the spreading of fake news by Internet trolls, there is a "news" service that respects all voices, inclusive of those on the Alt Right (Wrong) like Brietbart and the Daily Caller along with legitimate news outlets as a faux diversity of voices. Yet, Mr. Zuckerberg doesn't want government regulation or for Facebook to be broken up into smaller companies (though, I doubt he would starve).

Facebook and Twitter are "free" with the exception of gathering metadata on our browsing and spending habits and using it towards profiting of those same and other corporations. It can also be used nefariously by governments as discovered in 2016.

On this fiftieth anniversary of the Internet, we should recall the lesson from the fictional character, Spider-man: "with great power comes great responsibility."
 

Marking the anniversary, our founder and inventor of the web, Sir Tim Berners-Lee, said:

“It’s astonishing to think the internet is already half a century old. But its birthday is not altogether a happy one. The internet — and the World Wide Web it enabled — have changed our lives for the better and have the power to transform millions more in the future. But increasingly we’re seeing that power for good being subverted, whether by scammers, people spreading hatred or vested interests threatening democracy.

“A year ago, I called for a new Contract for the Web, bringing together governments, companies and citizen groups to come up with a clear plan of action to protect the web as a force for good. In a month’s time that plan will be ready. This birthday must mark the moment we take on the fight for the web we want.” *

Structured Light...

Structured light is a fancy way to describe patterns or pictures of light, but deservedly so as it promises future communications that will be both faster and more secure.

Quantum mechanics has come a long way during the past 100 years but still has a long way to go. In AVS Quantum Science researchers from the University of Witwatersrand in South Africa review the progress being made in using structured light in quantum protocols to create a larger encoding alphabet, stronger security and better resistance to noise.

"What we really want is to do quantum mechanics with patterns of light," said author Andrew Forbes. "By this, we mean that light comes in a variety of patterns that can be made unique—like our faces."

Since patterns of light can be distinguished from each other, they can be used as a form of alphabet. "The cool thing is that there are, in principle at least, an infinite set of patterns, so an infinite alphabet is available," he said.

Traditionally, quantum protocols have been implemented with the polarization of light, which has only two values—a two-level system with a maximum information capacity per photon of just 1 bit. But by using patterns of light as the alphabet, the information capacity is much higher. Also, its security is stronger, and the robustness to noise (such as background light fluctuations) is improved.

"Patterns of light are a route to what we term high-dimensional states," Forbes said. "They're high dimensional, because many patterns are involved in the quantum process. Unfortunately, the toolkit to manage these patterns is still underdeveloped and requires a lot of work."

Adaption and Extinction...

Though the movie poster is an attempt at dark humor, I do agree with the science. We're in a time of our history where science is being suborned to political and economic considerations, when we need it literally for survival.


From a biological perspective, there is no such thing as devolution. All changes in the gene frequencies of populations--and quite often in the traits those genes influence--are by definition evolutionary changes. The notion that humans might regress or "devolve" presumes that there is a preferred hierarchy of structure and function--say, that legs with feet are better than legs with hooves or that breathing with lungs is better than breathing with gills. But for the organisms possessing those structures, each is a useful adaptation.

Chief among these misconceptions is that species evolve or change because they need to change to adapt to shifting environmental demands; biologists refer to this fallacy as teleology. In fact, more than 99 percent of all species that ever lived are extinct, so clearly there is no requirement that species always adapt successfully. As the fossil record demonstrates, extinction is a perfectly natural--and indeed quite common--response to changing environmental conditions. When species do evolve, it is not out of need but rather because their populations contain organisms with variants of traits that offer a reproductive advantage in a changing environment.

Asteroid Stuff...

"We are made of star stuff." Carl Sagan

Consider the possibility that an asteroid may have transformed the picture of life on Earth — but forget the dinosaurs and the massive crater, and rewind an extra 400 million years from that dramatic moment.

Back then, life was primarily an oceanic affair and backbones were the latest in arrival on the anatomy scene. But unlike the asteroid that killed the dinosaurs 66 million years ago, this earlier space rock never made it to Earth. Instead, a collision in the asteroid belt flooded the solar system with so much dust that, given some other changes at the time, allowed life on Earth to flourish, new research suggests.

"Most important events in the history of life are like that," said Rebecca Freeman, a paleontologist at the University of Kentucky who specializes in this period but wasn't involved in the new research. "You get a really unique set of circumstances that all come together, and you get a really dramatic event that maybe seems like it should be due to one particular dramatic thing. But in reality, it's a more complicated system at play," she told Space.com.

The dramatic event scientists want to explain is a spree of new species. That outburst of life, which paleontologists call the Great Ordovician Biodiversification Event, took place in the oceans, which were inhabited mostly by spineless creatures. "This is really a world that is dominated by invertebrate marine organisms," Freeman said. "Probably the top predator would have been a cephalopod," likely an ancestral relative of today's chambered nautilus, with its intricate spiral shell.

But when Birger Schmitz, a geologist at Lund University in Sweden, went hunting for rock dating back 466 million years, he wasn't hoping to find fossilized nautiluses; he was looking for fossilized meteorites. And over the past couple of decades, he and his colleagues have found dozens of these fossilized meteorites in a Swedish limestone quarry. Each carries a chemical time stamp indicating that it was heated about 470 million years ago, and scientists have thought for a while that there might have been a massive asteroid collision around that time.

A fifty-year-old hypothesis predicting the existence of bodies dubbed Generic Objects of Dark Energy (GEODEs) is getting a second look in light of a proposed correction to assumptions we use to model the way our Universe expands.

If this new version of a classic cosmological model is correct, some black holes could hide cores of pure dark energy, pushing our Universe apart at the seams.

University of Hawaii astrophysicist Kevin Croker and mathematician Joel Weiner teamed up to challenge the broadly accepted notion that when it comes to the Universe's growing waistline, its contents are largely irrelevant.

"For 80 years, we've generally operated under the assumption that the Universe, in broad strokes, was not affected by the particular details of any small region," said Croker.

"It is now clear that general relativity can observably connect collapsed stars – regions the size of Honolulu – to the behavior of the Universe as a whole, over a thousand billion billion times larger."

Not only could this alternative interpretation of fundamental physics change how we understand the Universe's expansion, but we might need to also consider how that growth might affect compact objects like the cores of collapsing stars.

A material that remains a superconductor when heated to the boiling point of water has been predicted by physicists in China. Hanyu Liu, Yanming Ma and colleagues at Jilin University have calculated that lithium magnesium hydride will superconduct at temperatures as high as 473 K (200 °C).

The catch is that the hydrogen-rich material must be crushed at 250 GPa, which is on par with pressures at the center of the Earth. While such a pressure could be achieved in the lab, it would be very difficult to perform an experiment to verify the prediction. The team’s research could, however, lead to the discovery of more practical high-temperature superconductors.

Superconductors are materials that, when cooled below a critical temperature, will conduct electricity with zero resistance. Most superconductors need to be chilled to very low temperatures, so the holy grail of superconductivity research is to find a substance that will superconduct at room temperature. This would result in lossless electricity transmission and boost technologies that rely on the generation or detection of magnetic fields.

I will make a commentary on "Sharpie Gate" momentarily.

The Handmaid's Tale is a dystopian novel by Canadian author Margaret Atwood, originally published in 1985. It is set in a near-future New England, in a totalitarian state resembling a theonomy that overthrows the United States government. The novel focuses on the journey of the handmaid Offred. Her name derives from the possessive form "of Fred"; handmaids are forbidden to use their birth names and must echo the male, or master, whom they serve.

Beginning with a staged attack that killed the president and most of Congress, a radical political group calling itself the "Sons of Jacob", exploiting religious ideology closely resembling some traits of Christian Reconstructionism, launches a revolution. The United States Constitution is suspended, newspapers are censored, and what was formerly the United States of America changes drastically into a theonomic military dictatorship known as the Republic of Gilead. The new regime moves quickly to consolidate its power, overtaking all pre-existing religious groups, including traditional Christian denominations; and reorganizes society along a new militarized, hierarchical model of Old Testament-inspired social and religious fanaticism among its newly created social classes. Above all, the biggest change is the severe limitation of people's rights, especially those of women, making them unable to hold property, handle money, as well as forbidding them to read or write.

The story is told in the first-person narration by a woman called Offred. In this era of declining birth rates due to increasing infertility brought about by environmental pollution and radiation, she is one of those few women with healthy reproductive systems. Hence she is forcibly assigned to produce children for the ruling class of men "Commanders", and is known as a "Handmaid" based on the biblical story of Rachel and her handmaid Bilhah. Apart from Handmaids, other women are also classed socially and follow a strict dress code, ranked highest to lowest: the Commanders' Wives in blue, the Handmaids in red with the exception of white veils around their faces, the Aunts (who train and indoctrinate the Handmaids) in brown, the Martha's (cooks and maids) in green, "Econo-wives" who handle everything in the domestic sphere in stripes, young and unmarried girls in white and widows in black.

Aptly described by one viewer as "the prologue to The Handmaid's Tale", Netflix's The Family is the new docuseries taking the world by storm.

A deeply gripping tale, the critically acclaimed show tells the story of the clandestine Christian organization called 'The Family' and their hidden influence on U.S. politics.

Based on a true story, The Family is a docuseries that combines archival photos and interviews with dramatic reenactments to investigate a secret Christian organisation known as The Fellowship Foundation, colloquially referred to as 'The Family'.

Their Washington D.C.-based network, comprised solely of men, includes numerous high-powered politicians, diplomats and religious leaders from around the world, who conspire together to influence legislation on a global level.

Their leader is a man named Doug Coe, described in the trailer as "the most powerful man in Washington you've never heard of". Coe believed that God's work was best carried out away from the public eye.

The Family author, Jeff Sharlet wrote it and its follow on, C Street as warnings on the abuse of power by an un-elected political organization that has out-sized influence on the US government. We've accepted the National Prayer Breakfast as "normal," when in strict constructionist reading of The Constitution, flagrantly violates The First Amendment.

Margaret Atwood opined in interview that what she wrote in 1985 isn't something she dreamed up out of whole cloth: there are real-life analogs. What was dramatized in the book and now in the series as the overthrow of the federal republic, suspension of the US Constitution has a prologue we often don't see...until the "Sons of Jacob" think they can openly get away with violence. They may first have an ultra secret organization that no one except for one truthful author has ever heard about.

The joke is first evangelical literature in the 1970s and the 1980s focused on the "end times" as a terrible, awful future event to avoid. 2 Chronicles 7:14 was often quoted at the end of a popular litany of speculative literature as a cosmic "get out of jail" card with the almighty. It also calmed and soothed Christian writers' audiences enough to consider the next book in their careers of scaring the bejesus out of their readers.

For most of our nation’s history, White Christian America (WCA) set the tone for our national policy and shaped American ideals. But especially since the 1990s, WCA has steadily lost influence, following declines within both its mainline and evangelical branches. Today, America is no longer demographically or culturally a majority white, Christian nation.

Drawing on more than four decades of polling data, The End of White Christian America explains and analyzes the waning vitality of WCA. Robert P. Jones argues that the visceral nature of today’s most heated issues—the vociferous arguments around same-sex marriage and religious and sexual liberty, the rise of the Tea Party following the election of our first black president, and stark disagreements between black and white Americans over the fairness of the criminal justice system—can only be understood against the backdrop of white Christians’ anxieties as America’s racial and religious topography shifts around them.

The mythology of Star Trek likely germinated in the nightmares Gene Roddenberry and people steeped in Cold War "duck and cover" drills (me included), thought a lot about: would World War III be the existential LAST war? Worlds orbit suns as we now observe throughout the universe. They do not require air, water or life - sentient or otherwise, just gravity, planetary physics and an orbital path.

It is mythology because benevolent aliens happening upon a fledgling warp species is pure "Deus ex machina." Warp drive is as imaginative as unicorns. Aliens that can traverse vast distances would probably be indifferent, if not militant to a technologically emerging species. Roddenberry could have easily made them Klingons.

The short-lived Enterprise, debuting days after September 11, 2001, tried to document our unsteady first steps to the stars, prior to Federation bureaucracies, Prime Directives and the original intro that became The Captain's Oath.

The CBS streamed, so far sophomore seasoned Discovery series not only fleshed out Captain Christopher Pike - the previous USS Enterprise's highest ranking Starfleet officer - it briefly alluded to the third world war in season 2 regarding ex-pat Earthlings and a time-traveling Red Angel (no spoilers - stream, binge and catch up).

What's missing is the cause.

Lying about Hurricane Dorian like a third grader forging his 68 on a report card to an "88" before his parents see it. It is callous of the lives lost in the Atlantic (20 and counting); the height of narcissistic personality disorder, and also illegal.

18 U.S.C. §2074 makes it a crime to issue a counterfeit weather forecast, claiming that it was issued by the Weather Bureau.

Despite a rare rebuke by the National Weather Service, who ostensibly WORK for the orange twit, he doubled, tripled and QUADRUPLED down, exhaustively dragging us ALL into his mad Twitter reality where he is king for life, he is right all the time and his "great brain" is the purest of genius, even stable.

We pulled out of the nuclear arms deal with Iran with the impulsive, not thought through, non-reviewed action that let us walk out of the Paris Climate Accords. We may have to send troops to ensure Iran doesn't reconstitute it's nuclear enrichment program (what the deal was supposed to do); we may end up paying trillions mitigating the after effects of super heated ocean water resulting in climate change damages after calling it a "Chinese hoax."

2053 is the fictional start of the Trek timeline almost species ending third world war. Ten years after that, Zefram Cochrane flies the Phoenix and attracts the attention of Vulcans who are (as written), benevolent, logical and vegetarian. We weren't interesting until we warped, because apparently thermonuclear annihilation and near species extinction is rather boring on a galactic scale.

The "end" may not take thirty-four years. It might just take an errant tweet during a septuagenarian bowel movement in the midst of "executive time" to produce a demonstrably pathetic lie about Alabama...or, a mushroom cloud.

Homo Sapiens to Homo Stultus...a gross, but sadly fitting epitaph.

(Reuters) - SpaceX test-launched an early prototype of the company’s Mars rocket on Tuesday, unnerving residents near the Texas site and clearing another key hurdle in billionaire entrepreneur Elon Musk’s interplanetary ambitions.

After the launch, Musk congratulated engineers from SpaceX, short for Space Exploration Technologies Corp, and posted a photo of Starhopper touching down on its landing pad with billowing clouds of dust and sand rising from the ground.

“One day Starship will land on the rusty sands of Mars,” Musk tweeted.

The prototype, dubbed Starhopper, slowly rose about 500 feet (152 m) off its launch pad in Brownsville, Texas, and propelled itself some 650 feet (198 m) eastward onto an adjacent landing platform, completing a seemingly successful low-altitude test of SpaceX’s next-generation Raptor engine.

The Raptor is designed to power Musk’s forthcoming heavy-lift Starship rocket, a reusable two-stage booster taller than the Statue of Liberty that is expected to play a central role in Musk’s interplanetary space travel objectives, including missions to Mars.
