Topics: Entanglement, Quantum Optics, Quantum Mechanics

Natalia Herrera-Valencia and colleagues have successfully unscrambled entangled light after it has passed through a 2 m long multimode fiber. Led by Mehul Malik, the team at the Heriot-Watt University in Edinburgh tackled the challenge using entanglement itself. The research was done in collaboration with a colleague at the University of Glasgow and is described in a recent paper in Nature Physics.

Light passing through a disordered (or “complex”) medium like atmospheric fog or a multimode fiber gets scattered, albeit in a known manner. As a result, the information carried by the light gets distorted but is preserved, and extra steps are needed to access it. This gets especially tricky for the transport of entangled states of light because the medium muddles up the quantum correlations. The states get “scrambled” and “unscrambling” becomes necessary to retrieve the original entangled states.

“We are now faced with the fact that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there "is" such a thing as being too late. This is no time for apathy or complacency. This is a time for vigorous and positive action.”

― Martin Luther King Jr

From Middle English apocalips, from Latin apocalypsis, from Ancient Greek ἀποκάλυψις (apokálupsis, “revelation”), literally meaning "uncovering", from ἀπό (apó, “after”) and καλύπτω (kalúptō, “I cover”). Wiktionary

It is the 19th anniversary of September 11, 2001, now during a pandemic. What's been revealed:

  1. The Russians that attacked the 2016 elections are doing so in 2020, with the apparent blessing of their installed puppet. Not only is he deferential to Vladimir Putin, but he's also nauseatingly gracious to him and any world dictator. He derisively nicknames everyone he meets to troll them. He hasn't once Vlad, the impaler of democracies.
  2. The criminal enterprise masquerading as a political party (Max Boot names them the "gang of Putin") has conceded they have literally NOTHING they can sell the electorate on their policies: tax cuts for the rich don't cause economies to grow, or jobs to "trickle-down." All they can give the rubes is "white power," which doesn't mean anything if you can't buy a senator or congressman with your personal exchequer.
  3. Confirming conservative judges hasn't ended Roe vs. Wade, and even if it did, it wouldn't eliminate abortion completely, just transfer the personal decision to individual states. The original intent by Margaret Sanger was to eliminate "lessers" and the "feeble-minded," which meant a lot of black and brown people, through involuntary abortions and sterilizations. Hell, America had a whole bureau for it. It backfired when it became a form of bodily agency for white women, wrongly attributed to lower birth rates. It didn't HELP, but babies and daycare are expensive. That probably did it.
  4. It does ensure that, once the demographics changes are complete in 2045, they will be the guards of white supremacy - not democracy - at federal and state levels. Even though White Anglo Saxon Protestants be in the numerical minority, they will still be in a similar state as Apartheid South Africa: diminished, but in-charge.
  5. The Russian-installed puppet knew Coronavirus was airborne, that it would affect children: in February. He lied. We ran for our lives middle of March last semester. We were open, exposed. What would have been the result of a masking order on February 8th? I have no doubt it still would have been horrific, but how many lives would still be with us? I don't if we'd be heading for 200,000 soon; 400,000+ by the end of the year.
  6. The Coronavirus reveals that America by far is not "united." It is, in the title of author Isabel Wilkerson, arranged in a Caste system based on degrees of Melanin. Those with a preponderance of the pigmentation have to be demonized, violated, and killed. The reinforcement is by projection: monsters projecting their monstrosities on others. It is the origins of how we distribute wealth, resources, and health.
  7. The near 100 fires on the west coast of America are visible from satellite. More will be said about how this is NOT climate change than about how this is the direct result of it. Other than the frenzied rush to qualify a vaccine, we have no warp drives, nor do we have a "planet B." People in the midwest and other locations will shrug and ask, "why should they care?" This is similar to the resistance to give New York help during Hurricane Sandy. A repeat of item six, "United States" is an oxymoron.

Donald John Trump lied, and people died: hundreds of THOUSANDS of people. If he followed science, he would have had a mandatory mask mandate. If he followed science, he'd literally be sailing to re-election. If he just, didn't LIE! He said he "didn't want to panic us," but he's trying to scare the shit out of Levittown 1950s "suburban housewives" against the evil brown people from urban cities led by the scary black Senator Cory Booker, and invading hordes from the Mexican border!

“I felt like this was pretty urgent,” said De Kai, who was born in St. Louis, and is the son of immigrants from China. “I saw the country where I grew up, where my family lives [now mostly in the Bay Area], about to face this pandemic without knowing much about something as simple as wearing a mask to protect themselves and others.” In part, this comes from a cultural difference between East Asia, where masks have been routinely worn for decades to fend off pollution and germs, and other parts of the world. This includes the U.S., where people are unaccustomed to wearing masks, and, in the past, have sometimes been insensitive, even stigmatizing East Asians, many of whom had chosen to wear them in public prior to the pandemic, and had continued the practice in the aftermath of the SARS and MERS outbreaks. (In part, this habit was meant to show other people that they were concerned about transmitting the disease—something we in the West would do well to emulate.)

De Kai’s solution, along with his team, was to build a computer forecasting model they call the masksim simulator. This allowed them to create scenarios of populations like those in Japan (that generally wear masks) and others (that generally don’t), and to compare what happens to infection rates over time. Masksim takes sophisticated programming used by epidemiologists to track outbreaks and pathogens like COVID-19, Ebola, and SARS, and blended this with other models that are used in artificial intelligence to take into account the role of chance, in this case the randomness and unpredictability, of human behavior—for instance, when a person who is infected decides to go to a beach. De Kai’s team have also added some original programming that takes into account mask-specific criteria, such as how effective certain masks are at blocking the invisible micro-droplets of moisture that spray out of our mouths when we exhale or speak, or our noses when we sneeze, which scientists believe are significant vectors for spreading the coronavirus.

If 80% of Americans Wore Masks, COVID-19 Infections Would Plummet, New Study Says, David Ewing Duncan, Vanity Fair

Here's the ArXiv preprint paper to review. It takes ninth-grade reading comprehension. What you don't understand in terms can be discerned with a search engine.

Tomorrow is today, and every day we're being trolled by the so-called chief executive. He's bankrupting the nation like one of his casinos. He's exhausting us with his criminality, obvious mental deficiencies, and endless gaslighting.

He's revealing his ineptness, incompetence, and likely, complicit relationship with a foreign adversary. Of the 20,000 plus lies already documented from 2017 to this now, he cannot obfuscate his FIRST official lie as president*:

Before he enters on the Execution of his Office, he shall take the following Oath or Affirmation:– I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my ability, preserve, protect and defend the Constitution of the United States. U.S. Constitution, Article II, Section 1, Clause 8

*Putin's puppet is an accidental oval office resident, and a clear and present danger to the republic, as Oroborus (America) eats its own tail.

Joan Feynman...

Dr. Joan Feynman was "Surely, You're Joking," Nobel laureate Dr. Richard Feynman's baby sister, and an impressive scientist in her own right. We lost her in July. She broke through a lot of barriers that her science progeny are now, rightfully, walking through.

Joan Feynman, an astrophysicist known for her discovery of the origin of auroras, died on July 21. She was 93.

Over the course of her career, Feynman made many breakthroughs in furthering the understanding of solar wind and its interaction with the Earth’s magnetosphere, a region in space where the planetary magnetic field deflects charged particles from the sun. As author or co-author of more than 185 papers, Feynman’s research accomplishments range from discovering the shape of the Earth’s magnetosphere and identifying the origin of auroras to creating statistical models to predict the number of high-energy particles that would collide with spacecraft over time. In 1974, she would become the first woman ever elected as an officer of the American Geophysical Union, and in 2000 she was awarded NASA’s Exceptional Scientific Achievement Medal.

Feynman’s choice in pursuing a career as a scientist was often at odds with the expectations for women, especially the expectations for a wife and mother, but she persisted to become an accomplished astrophysicist. During the 2018 APS April Meeting, where Feynman spoke at the Kavli Foundation Plenary Session, she recalled her mother discouraging her childhood interest in science, calling “women’s brains too feeble,” likely a common belief at the time.</em>

For her fourteenth birthday, Richard gave Feynman a copy of Astronomy by Robert Horace Baker, a college-level physics text, that both taught her about physics and what was possible: Feynman credited a figure attributed to Cecilia Payne-Gaposchkin for proving to her that women could indeed have a career doing science.

As part of her research at JPL, Feynman identified the mechanism that leads to the formation of auroras and developed a statistical model to determine the number of high-energy particles expelled from coronal mass injections that would hit a spacecraft during its lifetime. After her retirement from a senior scientist position in 2003, Feynman continued to conduct research on the impact of solar activity on the early climate of the Earth and the role of climate stabilization in the development of agriculture.

Ruha Benjamin was the featured speaker on the DoSER webinar “Race to the Future? Values and Vision in the Design of Technology and Society.” | courtesy Ruha Benjamin

Topics: African Americans, African Studies, Futurism, Sociology

Technology is not unbiased, according to a scholar investigating the phenomenon of technological racism. As people recognize the embedded biases within technology, the growing and multifaceted tech justice movement is working to counter these biases, added the scholar.

Ruha Benjamin, a sociologist, and professor of African American studies at Princeton University whose work explores the social dimensions of science, technology, and medicine, spoke during the “Race to the Future? Values and Vision in the Design of Technology and Society” webinar hosted on Aug. 13 by the AAAS Dialogue on Science, Ethics and Religion program. DoSER facilitates dialogue between scientific and religious communities by hosting symposia and lectures on topics at the interface of science, ethics, and religion; training and supporting scientists on engagement with faith communities; and helping seminaries integrate science into their core curricula.

Webinar viewers were invited to consider which prejudices and values are incorporated into technologies such as search engines and AI algorithms and to identify methods to dismantle technological racism.

Technology is often spoken about as if it were a force separate from human influence, Benjamin said. Yet “human beings are behind the screen: our values, our ideologies, our biases, and assumptions.”

Benjamin also pointed out that the biases extend beyond individuals to the systems as a whole and the historical data inputted into the machines. Much in the way that racism exists in legal, educational, and health systems, it also becomes codified in computer systems, she said. For instance, searching for images of “professional hairstyles” and “unprofessional hairstyles” on Google brings up results that equate naturally Black hair with a lack of professionalism – search results that echo real-life biases, she said.

Docus of Proleeca

Name: Docus lem Laurel ol Sulto
Occupation: Teacher / Royal of Sulto
Inner Strength: Laughter and Wisdom
Inner Weakness: Caring too deeply at times

- Docus is an MC from the worlds of Al Cir. Originally born in Proleeca, and raised to become a ruler for one of its three largest nations, she took after her mother in being rather unorthodox. This easily-excitable soul manages to balance the roles of teacher and mentor at Proleeca's Light Academy, being a ruling authority for Sulto, and being a front-line warrior and general in the fight against the draka.

- In the books of Al Cir, Docus introduces herself to Daiu (MC) as her personal mentor and whisks her away to Proleeca. She plays a crucial role in Daiu's development as well as in the war, but never loses her childish antics.

About Proleeca: The world Proleeca is an "outcast" world, claimed to be cursed by providence, evident by their "odd skin" and lack of hair. Otherwise, people of the five linked worlds of Al Cir have skin tones and hair similar to people of our Earth. Proleecan dominate skin tones are red, blue, and green, and they are the only world of the five that exclusively lives underground as it is too hot to live on the surface.

Chronicler Commentary: It honestly took me a long time to figure out what to put as her "weakness." She's not OP - she certainly has her own flaws and is not remotely immortal - but this woman is genuinely incredible. The very first stories in T'vanna that I witnessed originated in the five worlds of Al Cir - with the entrance of Docus. She grinned widely, spread her arms, and said "Wondrous day, is it not!" ... I was captivated by her in an instant, and continued to traverse Al Cir through Daiu's eyes, guided by her energy to experience just how "wondrous" everything truly is.

City-Sized, Secure Quantum Network...

Physicists Create City-Sized Ultrasecure Quantum Network

Quantum cryptography promises a future in which computers communicate with one another over ultrasecure links using the razzle-dazzle of quantum physics. But scaling up the breakthroughs in research labs to networks with a large number of nodes has proved difficult. Now an international team of researchers has built a scalable city-wide quantum network to share keys for encrypting messages.

The network can grow in size without incurring an unreasonable escalation in the costs of expensive quantum hardware. Also, this system does not require any node to be trustworthy, thus removing any security-sapping weak links.

“We have tested it both in the laboratory and in deployed fibers across the city of Bristol” in England, says Siddarth Koduru Joshi of the University of Bristol. He and his colleagues demonstrated their ideas using a quantum network with eight nodes in which the most distant nodes were 17 kilometers apart, as measured by the length of the optical fiber connecting them. The team’s findings appeared in Science Advances on September 2.

Oumuamua...

Mystery of Interstellar Visitor 'Oumuamua Gets Trickier

Topics: Astrophysics, Space Exploration, Spaceflight

Oumuamua—a mysterious, interstellar object that crashed through our solar system two years ago—might, in fact, be alien technology. That’s because an alternative, non-alien explanation might be fatally flawed, as a new study argues.

But most scientists think the idea that we spotted alien technology in our solar system is a long shot.

In 2018, our solar system ran into an object lost in interstellar space. The object, dubbed ‘Oumuamua, seemed to be long and thin—cigar-shaped—and tumbling end over end. Then, close observations showed it was accelerating as if something were pushing on it. Scientists still aren’t sure why.

One explanation? The object was propelled by an alien machine, such as a lightsail—a wide, millimeter-thin machine that accelerates as it’s pushed by solar radiation. The main proponent of this argument was Avi Loeb, a Harvard University astrophysicist.

Most scientists, however, think ‘Oumuamua’s wonky acceleration was likely due to a natural phenomenon. In June, a research team proposed that solid hydrogen was blasting invisibly off the interstellar object’s surface and causing it to speed up. 

Now, in a new paper published Monday (Aug. 17) in The Astrophysical Journal Letters, Loeb and Thiem Hoang, an astrophysicist at the Korea Astronomy and Space Science Institute, argue that the hydrogen hypothesis couldn’t work in the real world—which would mean that there is still hope that our neck of space was once visited by advanced aliens—and that we actually spotted their presence at the time.

Here’s the problem with ‘Oumuamua: It moved like a comet, but didn’t have the classic coma, or tail, of a comet, said astrophysicist Darryl Seligman, an author of the solid hydrogen hypothesis, who is starting a postdoctoral fellowship in astrophysics at the University of Chicago.

Post Hoc Ergo Propter Hoc...

Public-opinion polling shows that Trump’s low opinion of American elections has practically become Republican Party orthodoxy. According to a Reuters/Ipsos poll released on Friday, Republicans have an “unprecedented” level of “concern and mistrust in the system.” Roughly 70 percent of Republican voters believe that if Hillary Clinton wins the election, it’ll be due to fraud. In both this poll and an NBC News/SurveyMonkey poll, only half of Republicans say they’d accept a Clinton victory. (In the latter poll, by contrast, 82 percent of Democrats said they would accept a Trump victory.)

 

This suspicious Republican electorate is joined by growing ranks of conservative politicians, pundits, and intellectuals. They’re all increasingly willing to say that the existing American political system is hopelessly flawed and needs to be rolled back to the days before blacks and women could vote. On the most obvious level, this can be seen in moves by Republican governors all over America to make voting more difficult, through stringent voting ID laws, new hurdles to registration, and the curtailment of early-voting options. Equally significant has been the gutting of key provisions of the Voting Rights Act by conservative Supreme Court justices in the 2013 Shelby Country v. Holder ruling.

 

Suspicion of the democratic system is so pervasive on the right because it’s driven by the fear that white Christian America is facing demographic doom. The evidence is right there in the election results: Republicans have lost the popular vote in five of the last six presidential elections, and if current polling trends hold, the GOP will be batting one for seven when the results come in on November 8. Thanks to gerrymandering, Republicans may hold on to a U.S. House majority for a while, and they’ll remain competitive in state capitols in the near future. But a whites-only party can’t win national elections. And over time, the GOP’s congressional and state fortresses will crumble if the party doesn’t change dramatically. Or if the democratic system doesn’t change dramatically.

 

The Right Is Giving Up on Democracy, Jeet Heer, The New Republic, October 24, 2016

 

The 2008 electorate was on-record as the youngest and most diverse in Pew Research history. It's why I think the right had a visceral reaction to President Barack Obama. He was the seventh African American to run for president in the modern era, and the first one to actually win. The trial balloon of a "post-racial" society was floated (see? We're not racist, you finally have a negro president). The 2012 re-election sent them over a cliff of brief self-reflection with the post-election GOP Autopsy, officially the Opportunity and Growth Project. That revelation was short-lived, and with past indicative revelations as prologue, quite reasonable and sane. State media/Fox propaganda and other conservative outlets couldn't help themselves. The faux "controversies" from Michelle Obama's bare arms (but not Melania Trump's bare behind), Grey Poupon mustard on hot dogs and tan suits seems delirious, hilarious, and deranged. It was a parade of the insane.

 

There are a pro and con to whether racism qualifies as a mental disorder. To those recipients of its attacks and largesse, it seems to fit the bill. I was the victim of a "Zoom bombing" recently, pornographic materials, and the n-word repeated to an online crowd of African Americans in a Sunday School meeting studying the Book of James: We'd lean "pro."

 

This demographics time bomb was set off by the aftermath of 1865: no longer having free slave labor, many legal machinations were attempted to re-enslave previously free African Americans using vagrancy laws, see "Slavery By Another Name," by Douglas A. Blackmon. The American Prison System exploits a loophole in the 13th Amendment: anyone arrested by the system - state, federal or for-profit - according to The Constitution is technically a slave of the state. We have Asian citizens because Chinese immigrants were imported to replace freed slaves on plantations. ICE likes to raid Hispanics/Latinos at food processing plants, but are missing the bonanza of brown targets at home builders, who probably couldn't offer their great home prices without company owners paying undocumented immigrants cash off-the-books, so as not to incur tax liabilities. Not a single home builder, for example, has done a perp walk.

Excerpt from "Black Labor, White Wealth: The Search for Power and Economic Justice," (August 1, 1994) Claude Anderson, Ed. D., Chapter 2: Power and Black Progress:

 

Chapter 2, page 33, subsection titled: Numerical Population Power 

 

In a democratic society, the numerical majority wins, rules, and decides. The theoretical rights of a minority, may or may not be respected, especially if they are a planned minority. Numerical population power is the power that comes to those groups that acquire power through their sheer size. The black population peaked in the 1750s when slaves and free blacks accounted for approximately 33 percent of the total population. The high numerical strength of blacks caused fear and concern among whites. They feared the loss of their own numerical power. Word of black Haitians successful slave revolt in the 1790s had spread across America and reportedly ignited several slave revolts in Southern states.

 

The First U.S. Congress enacted the first naturalization law that declared America to be a nation for "whites only." The naturalization act and other income incentives attracted a mass influx of legal and illegal European ethnics, followed by Asian and Hispanic immigrants a century later. The immigration quota for blacks remained zero until their total percentage of the population declined to nine percent. By making blacks a planned numerical minority, white society assured its dominance in a democratic society where the majority always wins.

Post Hoc Ergo Propter Hoc (Latin): after this, therefore because of this. It is an informal fallacy, meaning the fallacy originates in an error of reasoning rather than a flaw in the logical form of the argument. (Wikipedia) So, what WAS the original "argument"?

 

American mythology teaches that the early United States was founded by men of conscience who came to the "new world" in order to practice their religious convictions in peace and freedom. John Winthrop (1588–1649), the first governor of the Massachusetts Bay Colony, in particular, has been quoted as a source of inspiration by U.S. presidents from John F. Kennedy to Ronald Reagan.

 

Yet Winthrop did not represent a tradition of either democracy or religious tolerance. He hated democracy with a passion. The state he created did not hesitate to execute people like the Quakers and even brought to the "new" world the very popular tradition of medieval Europe, the trial and execution of witches.

 

"A Shining City on a Hill": Troubling information about a famous quote. The Puritan tradition of intolerance and John Winthrop, World Future Fund

 

We've taken The Constitution, our founding document, through historical apotheosis. Strict constructionists will say it is without flaw, and we should look for "original intent"; "breathing document" aficionados want constant change and continuous improvement, ever-becoming a "more perfect union."

 

The story we tell ourselves becomes muddled over time. This is similar to the game of "telephone," where my teacher whispered instructions to the first student in a line of fifth-graders from a 3 x 5 index card. Twenty-students deep, what we said and the meaning of what they said has irrevocably changed, similarly through essentially a 232-year relay.

 

We are here from Crispus Attucks to George Floyd, from sacrifices in revolts from England to knees-on-necks, no-knock raids, and killing teenagers carrying Arizona Tea and a bag of Skittles. We are here from Manifest Destiny, Trail of Tears, Black Wall Street-like genocides to Coronavirus pandemic. We are here because the original story of this country has become horribly distorted. That's not to say the original picture was perfect. For this republic's continuance, we desperately need to be honest with ourselves.

 

We're here because the country was based on slavery: the wealth of the nation built on the backs of free, uncompensated, kidnapped-from-Africa labor for generations.

 

We're here because those persons were described as a fraction, 3/5th's, and their children sold away like so much cattle.

 

We're here because the same slave owners defining us as inferior beings had unsolicited sex with us, siring Mulatto children in heterosexual rape of African women and "buck breaking" in homosexual encounters meant to emasculate African males in front of their females and families. Sally Hemings was not Thomas Jefferson's "lover": the relationship (or, the rape), started when she was fourteen. That is BY definition, pedophilia, and like all the aforementioned sexual acts above, sadistic.

 

We're here because the slaves, nor their descendants received reparations for years of enslavement, murder, and terrorism by the KKK, "sundown towns" requiring a Green Book to navigate around, and white citizen's councils.

 

We're here because such wealth exchange as reparations would dismantle the current biased system of white supremacy, and the reason it is opposed so strongly.

 

We're here because to justify the system, this nation built-in mythologies of superiority and inferiority, socially-engineered the society to self-fulfill the delusion, and codified it into laws. African Americans can be prejudiced, but they cannot be racist. Racism = prejudice + political power; the ability to codify your hatred with the strength of judiciary. Hitler did not "overthrow" the Weimar Republic: he won the election, seized control, and cloned Jim Crow on steroids in Europe, the only lesson the United States refuses to take ownership of.

 

We are here because unlike the logical fallacy: our current "this" is logically followed by the obvious "that." For us to have a new tomorrow - "[Built] Back Better," we're going to have to admit the sins of the nation's past, and in the vernacular of scripture: repent.

A shoddily tailored suit or a shrunken T-shirt may not be the most stylish, but wearing them is unlikely to hurt more than your reputation. An ill-fitting robotic exoskeleton on the battlefield or factory floor, however, could be a much bigger problem than a fashion faux pas. 

Exoskeletons, many of which are powered by springs or motors, can cause pain or injury if their joints are not aligned with the user. To help manufacturers and consumers mitigate these risks, researchers at the National Institute of Standards and Technology (NIST) developed a new measurement method to test whether an exoskeleton and the person wearing it are moving smoothly and in harmony. 

In a new report, the researchers describe an optical tracking system (OTS) not unlike the motion capture techniques used by filmmakers to bring computer-generated characters to life. 

The OTS uses special cameras that emit light and capture what is reflected back by spherical markers arranged on objects of interest. A computer calculates the position of the labeled objects in 3D space. Here, this approach was used to track the movement of an exoskeleton and test pieces, called “artifacts,” fastened to its user.

Scientists have found new evidence that Earth has been moving through the remains of exploded stars for at least the last 33,000 years.

In a new study published in the journal Proceedings of the National Academy of Sciences, a team of Australian researchers describes how they extracted a special isotope of iron called iron-60 from five deep-sea sediment samples using mass spectrometry.

That’s illuminating because as the researchers wrote in their paper, the isotope is “predominantly produced in massive stars and ejected in supernova explosions.” In other words, iron-60 is left over after a star explodes.

And because iron-60 is radioactive and decays in 15 million years, the theory is that our planet is continuously being dusted with the stuff as it’s moving through the “Local Interstellar Cloud,” a region of unclear origins made up of gas, dust, and plasma.

Gothic Fantasy Short Stories
Black Sci-Fi Anthology

The Black Sci-Fi Short Stories anthology is due to be published in April 2021 (UK) and June 2021 (US), in our Gothic Fantasy series, joining existing titles such as A Dying Planet, Time Travel, Alien Invasion, Endless Apocalypse, Robots & Artificial Intelligence, Dystopia Utopia and more.

As always, we are keen to encourage new writers, without prejudice to age, background or previous publication history. It’s the story that matters, and the quality of writing. Please read through the details for submissions carefully before submitting your stories and make sure to include the project name in the subject of your email.

Diversity in all aspects of publishing still has a long way to go, especially the presentation of black voices. So, as well as offering great but neglected stories that deserve to be more widely read, this latest book in our Gothic Fantasy series will be a long-overdue step for us towards pro-actively rectifying the imbalance, by devoting a whole volume to work by black writers in science fiction, new and old. Of course, science fiction sits at the core of our own publishing, and offers an invaluable forum for exploring social issues past, present and future.

With a foreword by Alex Award-winning novelist Temi Oh, an introduction by Sandra M. Grayson, author of Visions of the Third Millennium: Black Science Fiction Novelists Write the Future (2003), and invaluable promotion from Tia Ross and the Black Writers Collective and more, this latest offering in the Flame Tree Gothic fantasy series focuses on an area of science fiction which has not received the attention it deserves. Many of the themes in Sci-fi reveal the world as it is to others, show us how to improve it, and give voice to the many different expressions of a future for humankind.

Dystopia, apocalypse, gene-splicing, cloning, colonization and much more can be explored here – in fantastic stories, whether informed by the black experience or not. The selected submissions will be combined with writing of an older tradition (by authors such as Martin Delany, Edward Johnson, Pauline Hopkins and W.E.B. Dubois) whose first-hand experience of slavery and denial created their living dystopia.

Word count is approx. 2000–4000 and submissions will be accepted between 24th August and 21st September – please send to 2020@flametreepublishing.com, ensuring ‘Black Sci-Fi’ is in the subject line.

The fin LED pixel design includes the glowing zinc oxide fin (purple), isolating dielectric material (green), and metal contact (yellow atop green). The microscopic fins, which the research team arranged into comb-like arrays, show an increase in brightness of 100 to 1,000 times over conventional submicron-sized LED designs.

A new design for light-emitting diodes (LEDs) developed by a team including scientists at the National Institute of Standards and Technology (NIST) may hold the key to overcoming a long-standing limitation in the light sources’ efficiency. The concept, demonstrated with microscopic LEDs in the lab, achieves a dramatic increase in brightness as well as the ability to create laser light — all characteristics that could make it valuable in a range of large-scale and miniaturized applications.

The team, which also includes scientists from the University of Maryland, Rensselaer Polytechnic Institute, and the IBM Thomas J. Watson Research Center, detailed its work in a paper published today in the peer-reviewed journal Science Advances. Their device shows an increase in brightness of 100 to 1,000 times over conventional tiny, submicron-sized LED designs.

Family Portrait

 

Beloved daughter dear of mine
Chosen by the Three Divine
Precious being at your birth
Will you ever know your worth...?

They tell me to let you go,
That you were born for such, and so
All onlookers say to me:
"What a blessing this child be!"

One day, just as is foretold,
I won't have your hand to hold.
You will go to Far Away
And I will ever mourn that day.

Ages pass before you'll see
How much you had meant to me.
But until then, with tears to trace,
I'll keep you in my embrace

And try to stave the hands of time,

Most beloved dear of mine.

 

(A poem from the heart of Kina's mother, in my coming "A Mikal's Child" series.)

 

If you gave birth to a child who you *knew* would randomly leave home on their own before they were five years old based on a prophecy, would you fight against that prophecy or agree with others in society to simply accept what will happen?
