Researchers in Spain and Italy have constructed the first-ever quantum phase battery – a device that maintains a phase difference between two points in a superconducting circuit. The battery, which consists of an indium arsenide (InAs) nanowire in contact with aluminium (Al) superconducting leads, could be used in quantum computing circuits. It might also find applications in magnetometry and highly sensitive detectors based on superconductors.

In a classical battery (also known as the Volta pile), chemical energy is converted into a voltage difference. The resulting current flow can then be used to power electronic circuits. In quantum circuits and devices based on superconducting materials, however, current may flow without an applied external voltage, thus dispensing with the need for a classical battery.

The concept of a quantum phase battery was studied theoretically in 2015 by Sebastián Bergeret of the Material Physics Center (CFM-CSIC) and Ilya Tokatly at the University of the Basque Country in Donostia-San Sebastián, Spain. Their battery design comprised a combination of superconducting and magnetic materials and was based on a Josephson junction – a non-superconducting region through which the Cooper pairs responsible for superconductivity can tunnel. This semiconducting “weak link” provides a persistent phase difference between the superconductors in the circuit, similar to the way that a classical battery provides a persistent voltage drop in an electronic circuit. Thanks to this phase difference, a superconducting current (that is, a current with zero dissipation) flows when the junction is embedded in the superconducting circuit.

This will be the first splashdown that's occurred in a while, but particularly during a global pandemic and the internment of a legend. It was germane during the Mercury, Gemini and Apollo programs. The Space Shuttle brought to mind the CGI and FX ease of take offs and landings in Science Fiction movies, regardless of genre: somehow massive spaceships can magically levitate, and "ease" into orbit without accelerating to escape velocity in a planet's gravity well.

Today, we're laying to rest a civil rights icon, John Robert Lewis. He was BLM before the Internet and hashtag. He was notorious for getting in "good trouble," leading a sit-in on the House floor - breaking rules for twenty children and six adults slaughtered at Sandy Hook, for what he and Dr. King called "The Beloved Community." Like moonshots, that was "conspiracy theorized" away, callously, but revelatory of how depraved this republic was before this current moment. Hopefully, the citizens of Alabama will rename the bridge currently carrying the name of a confederate traitor and Klan grand dragon in HIS distinct honor.

During splashdowns and pandemics: I can dream.

NASA will provide live coverage of activities leading up to, during, and following the return of the agency’s SpaceX Demo-2 test flight with the agency’s astronauts Robert Behnken and Douglas Hurley from the International Space Station.

The duo arrived at the orbiting laboratory on May 31, following a successful launch on May 30 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida.

NASA and SpaceX are targeting 7:34 p.m. EDT Saturday, Aug. 1, for undocking of the Dragon “Endeavour” spacecraft from the space station and 2:42 p.m. Sunday, Aug. 2, for splashdown, which will be the first return of a commercially built and operated American spacecraft carrying astronauts from the space station.

Coverage on NASA TV and the agency’s website will begin at 9:10 a.m., Aug. 1, with a short farewell ceremony on station and resume at 5:15 p.m., with departure preparations through splashdown and recovery at one of seven targeted water landing zones in the Atlantic Ocean or Gulf of Mexico off the coast of Florida.

All media participation in news conferences and interviews will be remote; no media will be accommodated at any NASA site due to the ongoing COVID-19 pandemic. To participate in the briefings by phone or to request a remote interview with the crew members, reporters must contact the newsroom at NASA’s Johnson Space Center in Houston at 281-483-5111 no later than two hours prior to each event.

We have always held to the hope, the belief, the conviction that there is a better life, a better world, beyond the horizon. Franklin D. Roosevelt

At 1 pm eastern, 12 noon in San Antonio, my wife's family laid her favorite uncle to rest, a U.S. veteran. He died due to health complications, non-COVID. Because of the pandemic, we had to say our tearful goodbyes over Facebook live, the participants' voices muffled by masks singing "It is Well." He lived a good life, into his eighties, longer than my own father, but his sons probably don't take solace in his longevity: their hero is gone for now.

Dr. Eddie Glaude, Jr's book on James Baldwin downloaded on my Kindle about a week before Dr. Mary Trump's book about her uncle. They are my mental comfort food between writing a research proposal: a book written by an African American heterosexual professor about an LGBT Civil Rights icon, and a book about an unstable, reckless sociopath, written by his niece, a Lesbian, a notion now in a world with Ellen DeGeneres and Rachel Maddow is almost cliche. "Jimmy" was out and proud before it was relatively safe, or sane. He literally could have been killed for "the color of his skin, and the content of his character." But that did not stop or stifle his boldness.

“I love America more than any other country in the world and, exactly for this reason, I insist on the right to criticize her perpetually.” ― James Baldwin

We are "betwixt and between" the past and the future: one written and one yet-to-be written, first by John Lewis and now, Black Lives Matter et al. We are betwixt and between love and hate, democracy and fascism; working towards a more perfect union, and barreling towards totalitarianism. The philosophies of Hitler, Goebbels and Himmler are personified in Bannon, Gorka and Miller, fascist whisperers recycling hate in the 21st century: the ovens now microscopic, efficient, utterly malevolent, and unseen. We are seeing the NRA's "jackbooted thugs" deployed in American cities - Portland, Oregon, soon Chicago, Illinois; our nation's birthplace in Philadelphia, Pennsylvania and any other blue-governed city, without a peep from them, as deafening a silence now as for the death-by-police of the licensed gun owner, Philando Castile. The second amendment might be outlawed to Melanin in a dictatorship.

The best political weapon is the weapon of terror. Cruelty commands respect. Men may hate us. But, we don't ask for their love; only for their fear. Heinrich Himmler, commander of the German Schutzstaffel (SS) and Gestapo.

“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.

For Dr. Eddie Glaude, Jr., that fierce urgency is he, I and previously "Jimmy" living in these black bodies, witnessing the country careen from "hope and change" to this dark moment of running over civil rights demonstrators in Charlottesville, Nazis in polo shirts carrying tiki torches; or teargassing peaceful George Floyd demonstrators on the Washington Mall. Once we got over the "post-racial America" shtick, it didn't take long to see the new black president hung in effigy, called the n-word almost daily, burned at the stake, bone through the nose as witch doctor for the pejorative: Obamacare. They prayed Psalm 109:8-15, for his death and desolation. They are anti-Christians for an Antichrist. Their hatred of immigrants in chat rooms and over the pit of hell summoned eventually a demon, who recycled for them Hitler, the Klan and Reagan's slogan: make America great again. Exposed in Dr. Glaude's treatise was what Eddie and "Jimmy" referred to as the American lie, broadcast with the hubris of a birther foghorn.

For Dr. Mary Trump, that fierce urgency was living through a slow train wreck: watching her father, Freddy - Fred Trump's namesake - taken apart by her grandfather brick-by-brick until there was nothing left. She could still live in the comfort of privilege, station and American aristocracy: her bloodline leading directly to the seat of power almost infinite. All she had to do was keep her head low and flatter a narcissist. Her clinical training tells her there is no pleasing such a person. His needs are a bottomless pit next to a black hole. His loyalty is demanded of others and expendable to the same. Just as the senior sociopath dismantled her father, her training said a prolific lying, mentally disturbed, gaslighting and violent man could dismantle a nation.

Mary L. Trump, Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man

Perhaps she thought of Martin Niemöller:

First they came for the socialists, and I did not speak out—because I was not a socialist.

Then they came for the trade unionists, and I did not speak out— because I was not a trade unionist.

Then they came for the Jews, and I did not speak out—because I was not a Jew.

Then they came for me—and there was no one left to speak for me.

It is easy to fill in the blank now: African Americans, Hispanics/Latinos, Women, Homosexuals, Lesbians, Transgenders: if we do not speak for our fellow humans, we follow them into the COVID ovens. A pandemic as eugenics is far more efficient, less visible and more excusable than public crematoriums.

I still have hope. I have to. I have a granddaughter barely over a year old, and she DESERVES a future.

Politics in America especially is organized tribalism. The factions George Washington warned about in his farewell address express themselves as republicans and democrats, along with greens and independents.

We are all between yesterday and tomorrow, living out our hyphens. We are ever all in "the fierce urgency of NOW" for tomorrow. We all have children, or know children, and a world that looks like a dystopian novel is only appealing to sociopaths, mass murderers and death cult members. A world like that has few children, and the human species - Coronavirus, climate change, or nuclear exchange - is then in peril.

For this election, for humanity, we have to ALL be Americans, and heroes in the spirit of John Lewis: voting by mail, voting early, getting in "good trouble" for this fleeting, precious thing called democracy: made real by the struggles of the downtrodden and "the least of these." For "the fierce urgency of now," for a "better world beyond the horizon"... for tomorrow.

“never lose sight, as we finger the pain and disillusionment of our after times, of the possibility of a New Jerusalem.” ― Eddie S. Glaude Jr., Begin Again: James Baldwin's America and Its Urgent Lessons for Our Own

The first direct image of two exoplanets orbiting a Sun-like star, seen here, was captured by the SPHERE instrument on the ESO’s Very Large Telescope. The system is called TYC 8998-760-1 and is located some 300 light-years from Earth.

In another exoplanetary first, the European Southern Observatory's Very Large Telescope (VLT) in Chile's Atacama Desert has captured an image of two worlds orbiting a younger version of the Sun. The system, called TYC 8998-760-1, is located roughly 300 light-years away in the southern constellation Musca. And although it hides two gas giants orbiting a Sun-like star, we don’t have anything quite like these worlds in our own solar system.

The inner planet lies about 160 astronomical units from its host star (where one astronomical unit, or AU, is the average Earth-Sun distance) and is some 14 times the mass of Jupiter. With that amount of heft, the gas giant skirts the border between planet and brown dwarf, which is a type of almost-star. The more distant planet is located about 320 AU from its star and weighs in at about six Jupiter masses.

Some red-giant stars are rotating much faster than previously thought, according to a study led by Patrick Gaulme at Germany’s Max Planck Institute for Solar System Research. Using NASA’s Kepler space telescope, the astronomers found that about 8% of the red giants they observed are rotating fast enough to display starspots. The team reckons that the elderly stars acquire their rapid rotation by following one of three distinct routes in their evolution.

In main sequence stars like the Sun, the complex interplay that occurs between stellar rotation and the motions of plasma creates incredibly lively magnetic fields. When this magnetic activity is particularly strong, upwelling plumes of plasma in a star’s convective outer layers can be blocked, producing dark patches on its surface. To an observer on Earth, these starspots cause a periodic variation in the star’s brightness as it rotates, bringing the spots in and out of our field of view.

Until recently, starspots were not thought to be present on red giant surfaces. Since these older stars expand rapidly as they move out of the main sequence, while maintaining their angular momentum, previous theories had predicted that they must rotate more slowly than main sequence stars. Slower rotation should reduce magnetic activity, preventing starspots from forming.

Comet NEOWISE has been entertaining space enthusiasts across the Northern Hemisphere. Although its official name is C/2020 F3, the comet has been dubbed NEOWISE after the Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) space telescope that first noticed it earlier this year. This “icy snowball” with a gassy tail made its closest approach to the sun on July 3 and is now heading back from whence it came: the far reaches of the outer solar system. Its long, looping orbit around our star ensures that after passing closest to Earth on July 22, Comet NEOWISE will not return for some 6,800 years.

Even though the comet is now bright enough to observe with unaided eyes, inexperienced stargazers might have trouble knowing when and where to look. Scientific American spoke to Jackie Faherty, an astronomer at the American Museum of Natural History in New York City, for observing tips and a better appreciation of why comets are so special.

How does one prepare to watch Comet NEOWISE with the naked eye?

Find the darkest possible swath of sky and make sure your eyes are adjusted so that you give yourself the best possible opportunity to see faint objects. It means: don’t just walk outside after staring at lights or screens and expect to see [the comet] really well. You need 15 minutes or so to adjust your eyes, so that your pupils are adjusted, and they’re used to seeing fainter things. It’s the same as walking into a dark room, and everybody knows that [you] can’t see [things] first—and then, all of a sudden, you start seeing things. You need to do the same thing when you walk outside. And use the Comet NEOWISE app developed by astrophysicist Hanno Rein of University of Toronto Scarborough to see exactly where it is, so that you know what direction you need to look. And then the key would be to find yourself a place that is the darkest possible, that [has] no lights.

On June 21, 1964, three young men disappeared near the town of Philadelphia, Mississippi. Michael (Mickey) Schwerner and James Chaney worked for the Congress of Racial Equality (CORE) in nearby Meridian; Andrew Goodman was one of the hundreds of college students from across the country who volunteered to work on voter registration, education, and Civil Rights as part of the 1964 Mississippi Summer Project. The three men believed their work was necessary, but also dangerous: Ku Klux Klan membership in Mississippi was soaring in 1964 -- with membership reaching more than 10,000. The Klan was prepared to use violence to fight the Civil Rights movement; on April 24 the group offered a demonstration of its power, staging 61 simultaneous cross burnings throughout the state.

The case was drawing national attention, in part because Schwerner and Goodman were both white Northerners. Mickey Schwerner's wife Rita, who was also a CORE worker, tried to convert that attention to the overlooked victims of racial violence. “The slaying of a Negro in Mississippi is not news. It is only because my husband and Andrew Goodman were white that the national alarm has been sounded,” she told reporters during the search.

Throughout July, investigators combed the woods, fields, swamps, and rivers of Mississippi, ultimately finding the remains of eight African American men. Two were identified as Henry Dee and Charles Moore, college students who had been kidnapped, beaten, and murdered in May 1964. Another corpse was wearing a CORE t-shirt. Even less information was recorded about the five other bodies discovered.

Finally, after six weeks of searching, a tip from an informant -- later identified as Mississippi Highway Patrol officer Maynard King -- sent investigators to an earthen dam on the Old Jolly Farm outside Philadelphia. It was there that the FBI uncovered the bodies of Schwerner, Chaney, and Goodman on August 4.

Russian financial traffic got to the Taliban in Afghanistan: intelligence wouldn't use the word "bounty."  The scandal is there was no reaction or retaliation from the Commander-in-Chief*. In schoolyard parlance, Putin knocked the board off Orange Satan's shoulder, and he slunk away to get into a Twitter spat with a pack of mean middle school students. Twitter saw hacks Elon Musk, Barack Obama, Joe Biden (hopefully, the successor of Satan), and a lot of other prominent American accounts for a bitcoin scam. I can't imagine this wasn't Putin: he has no push back to any actions in the world he's taking. (Noticeably, Tangerine Nit Twit's account was fine.) Russians are also interested in our vaccine information, because a recovering America during a pandemic to them, is a threat.

Deafening silence (still) from a law-and-order president* and his politically compromised party complicit with a hostile foreign power.

* Putin's puppet, if you didn't already know.

Realize: This republic's unraveling has been an ongoing project. It was held together by spit, glue and duct tape. Every step forward by the marginalized has always experienced backlash. Corey Robin in "The Reactionary Mind: Conservatism from Edmund Burke to Sarah Palin" states: Conservatism is the theoretical voice of this animus against the agency of the subordinate classes, i.e. people get pissed off about getting pissed on, and the ones over them calling it rain. This spawns Civil Rights, Women's Rights, LGBT rights movements, because a few of us actually read The Constitution. Jimmy Carter was our first openly evangelical president, and supported by none other than types like Michelle Bachmann. However, he ran afoul when he tried to get Bob Jones University to follow the law, and not be so racist with miscegenation (a fancy word for no interracial dating). Hopping on the abortion bandwagon was an easy dodge that I don't think they ever meant to win, as Corey Robin noted, the war against an enemy was the most important thing. This led them to their first sale of a piece of their souls to a B-movie actor, Ronald Reagan.

Reagan knowingly started his campaign within meters of the murders of Chaney, Goodman and Schwerner in Philadelphia, Mississippi. This was genteel wink-and-nod politics, giving plausible denial to moderate whites and black republicans that could then both deny the subtle racism directly before them. Since Charlottesville and before it when IT descended that escalator in Trump tower, it's been a foghorn, and only a blind/deaf/dumb man could miss his self-admittance the alt-right, Neo Nazis and KKK can recognize. Every tax cut, then and since Reagan, has been a damned lie of trickle down; pissing on us, and still telling us it's rain. Hell, why change the shtick if it's still working after forty years? It's not a huge stretch from a B-movie actor to a reality show nincompoop.

I purchased Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man, by Dr. Mary L. Trump, feeling better contributing to its rise on the New York Times Bestseller List than John Bolton's (I canceled it when I found out he influenced the disbanding of the pandemic response team). Not that there wasn't a cottage industry that's used their access to this criminal to like Bolton, cash-in. Dr. Trump is a clinical psychiatrist specializing in psychopathy and sociopathy. She is also, by her last name: his niece. She is similar (to me) Marilyn Munster - "plain" by Munster norms - but normal to everyone else viewing the sitcom. In it, the mansion that Fred Trump met out his sociopathic abuse that produced our current president* was simply referred to as "The House."

The "Fall of the House of Usher" is a classic Gothic short story by the master of the macabre, Edgar Allen Poe. In it, the unnamed narrator makes the dysfunction of the Usher family - only one heir per generation - and the house itself one in the same. There is a suggestion this genetic problem might be the result of incest, since they only manage to have one heir per generation.

The narrator's friend Roderick buries his twin sister, Madeline after suffering catalepsy, defined as the loss of control of one’s limbs. Dictionary.com says "a physical condition usually associated with catatonic schizophrenia, characterized by suspension of sensation, muscular rigidity, fixity of posture, and often by loss of contact with environment." Poe sure could pick the sickness!

Madeline "dies" (even before comics, there's a loophole), buried; only to emerge bloodied from the grave she escaped and attacks her brother (who wouldn't, buried alive?). She dies from her wounds, Roderick dies from apparent cardiac arrest and the house poetically collapses with the death of both heirs as the narrator sprints.

Brian Kemp is suing the city of Atlanta, its mayor and other municipalities to stop them from wearing masks, so...he can spread Coronavirus more efficiently? It's about as sensible as hocking Goya beans as refrigerator trucks and bodies are piling up.

I voted for the smart woman last time. I'm voting for the sane candidate this time as well: he models wearing a mask. I will crawl over broken glass, swim molten lava; wrestle man-eating crocodiles to end this dystopian nightmare. It's way past if we "love" Joe Biden: we need to overwhelm the cheating, voter suppression, the Russians hacking/disinformation and affect repairs to the framework of a crumbling republic.

However: If this house disintegrates, this narrator's passport is current.
