Cate Cox and Brittany Watts: Their last names rhyme, but their circumstances couldn’t be more diametrically different from one another.

Cate Cox is a married suburban mother with two children. She previously lived in a suburb of Dallas, Texas, but due to her condition, she had to flee her state. A complication with her pregnancy put her life at risk and the possibility that she might not be able to conceive again if her pregnancy weren’t ended expeditiously through a procedure now outlawed in Texas.

Brittany Watts, an African American woman, had a stillborn, unfortunately, in the toilet. The fetus was found in the drain, and she was charged with abuse.

Mrs. Cox eventually left Texas for the procedure, having the financial means to leave and get the healthcare that she desired.

Ms. Watts was a frightened young woman who had left the hospital twice before her miscarriage. Yet she’s charged with felony abuse of a corpse in Ohio.

The Effects of the Dobbs Decision on Fertility*

The U.S. Supreme Court decision in Dobbs v. Jackson Women’s Health Organization sparked the most profound transformation of the landscape of abortion access in 50 years. We provide the first estimates of the effects of this decision on fertility using a preregistered synthetic difference-in-differences design applied to newly released provisional natality data for the first half of 2023. The results indicate that states with abortion bans experienced an average increase in births of 2.3 percent relative to states where abortion was not restricted.

The Dobbs Decision was a strategic salvo shot at the year 2045:

New census population projections confirm the importance of racial minorities as the primary demographic engine of the nation’s future growth, countering an aging, slow-growing, and soon-to-be-declining white population. The new statistics project that the nation will become “minority white” in 2045. During that year, whites will comprise 49.7 percent of the population in contrast to 24.6 percent for Hispanics, 13.1 percent for blacks, 7.9 percent for Asians, and 3.8 percent for multiracial populations (see Figure 1).

The shift is the result of two trends. First, between 2018 and 2060, gains will continue in the combined racial minority populations, growing by 74 percent. Second, during this time frame, the aging white population will see a modest immediate gain through 2024 and then experience a long-term decline through 2060, a consequence of more deaths than births (see Figure 2)

24.6 (Hispanics) + 13.1 (African Americans) + 7.9 (Asians) + 3.8 (Multiracial) + 0.9 (Other) = 50.3%, which is apparently an existential crisis on the right because “white” supremacy is anxiously numerical.

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 ethnicities, 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. Source: Sample chapter

Hence, a national ban is actually what they want. Fifteen weeks will be sold as a “reasonable” compromise, and then it will be paired down to the goose egg that is the actual target. Hence, the hostility towards mixed-race couples and multiracial children from their union: they’re not on the “white” team. Hence, the hostility towards the LGBTQ community and whether or not they conceive by surrogate or artificial insemination, their union does not produce enough “white” babies to maintain a numerical majority for the “white” team. Mrs. Cox and upper-middle-class suburban women like her will always have the means and the money to flee any complications and save future childbearing years. Ms. Watt will have one of two options: either flush her undesired fetus while in a state of shock down a toilet or die from complications that she cannot afford to mitigate.

The American Eugenics Movement, unfortunately, had a boost from prominent scientists who wished to rid the world of the “feebleminded” and the unfit. They did this through forced sterilization and control over who could get married (to procreate in the first place). If you’ve ever used the terms “well-bred” or “good breeding,” those originate from eugenics, now accepted as a pseudoscience, once promoted by one of the founders of the transistor and Nobel laureate in Physics, William Schockley. Coupled with southern Jim Crow, eugenics-on-steroids in the hands of the Nazis led to the Holocaust.

Nazi authorities created the Lebensborn program to increase Germany’s population. Pregnant German women deemed “racially valuable” were encouraged to give birth to their children at Lebensborn homes. During World War II, the program became complicit in the kidnapping of foreign children with physical features considered “Aryan” by the Nazis.

If one is desperate to maintain a majority or “goose your numbers,” you might be capable of anything to achieve those ends.

Very soon in the founding of a new nation, however, White Christians began to establish their well-being by using the resources, bodies, and lives of others. Through their own “witchcraft,” European Christians employed a mysterious and threatening potency that was the practice of using the other for their own gain. In [James W.] Perkinson’s description, through the projects of modern Christian empire “a witchery” of heretofore unimaginable potency ravaged African and aboriginal cultures…For Perkinson, the witchcraft of White supremacy was conjured through racial discourse as an ideological and practical frame that he identifies as the ‘quintessential witchery of modernity.’… In Perkinson’s chilling words, “Whiteness, under the veneer of its ‘heavenly’ pallor, is a great grinding witch tooth, sucking blood and tearing flesh without apology.”

The promise of nanotechnology, the engineering of machines and systems at the nanoscale, is anything but tiny. Over the past decade alone, there has been an explosion in research on how to design and build components that solve problems across almost every sector, and nanotechnology innovations have led to huge advancements in our quest to address humanity’s grand challenges, from healthcare to water to food security.

Like any area of scholarship, there are still so many unknowns. And yet, there are more talented scientists and engineers endeavoring to better comprehend and harness the power of nanotechnology than ever before. The future is bright for nanotechnology and its applications.

In celebration of its 20th anniversary, the National Center for Nanoscience and Technology, China (NCNST), a subsidiary of the prestigious Chinese Academy of Sciences, partnered with Science Custom Publishing to survey nanoscience experts from the journal and across the globe about the most knotty and fascinating questions that still need to be answered if we are to advance nanotechnology in society.

Abstract

The technical and intellectual capabilities of past societies are reflected in the monuments they were able to build. Tracking the provenance of the stones utilized to build prehistoric megalithic monuments through geological studies is of utmost interest for interpreting ancient architecture as well as contributing to their protection. According to the scarce information available, most stones used in European prehistoric megaliths originate from locations near the construction sites, which would have made transport easier. The Menga dolmen (Antequera, Malaga, Spain), listed in UNESCO World Heritage since July 2016, was designed and built with stones weighing up to nearly 150 tons, thus becoming the most colossal stone monument built in its time in Europe (c. 3800–3600 BC). Our study (based on high-resolution geological mapping as well as petrographic and stratigraphic analyses) reveals key geological and archaeological evidence to establish the precise provenance of the massive stones used in the construction of this monument. These stones are mostly calcarenites, a poorly cemented detrital sedimentary rock comparable to those known as ‘soft stones’ in modern civil engineering. They were quarried from a rocky outcrop located at a distance of approximately 1 km. In this study, it can be inferred the use of soft stone in Menga reveals the human application of new wood and stone technologies, enabling the construction of a monument of unprecedented magnitude and complexity.

The provenance of the stones in the Menga dolmen reveals one of the greatest engineering feats of the Neolithic. Scientific Reports, Nature

Nano Racetracks…

In this image, optical pulses (solitons) can be seen circling through conjoined optical tracks. (Image: Yuan, Bowers, Vahala, et al.) An animated gif is at the original link below.

(Nanowerk News) When we last checked in with Caltech’s Kerry Vahala three years ago, his lab had recently reported the development of a new optical device called a turnkey frequency microcomb that has applications in digital communications, precision timekeeping, spectroscopy, and even astronomy.

This device, fabricated on a silicon wafer, takes input laser light of one frequency and converts it into an evenly spaced set of many distinct frequencies that form a train of pulses whose length can be as short as 100 femtoseconds (quadrillionths of a second). (The comb in the name comes from the frequencies being spaced like the teeth of a hair comb.)

Now Vahala, Caltech’s Ted and Ginger Jenkins, Professor of Information Science and Technology and Applied Physics and executive officer for applied physics and materials science, along with members of his research group and the group of John Bowers at UC Santa Barbara, have made a breakthrough in the way the short pulses form in an important new material called ultra-low-loss silicon nitride (ULL nitride), a compound formed of silicon and nitrogen. The silicon nitride is prepared to be extremely pure and deposited in a thin film.

In principle, short-pulse microcomb devices made from this material would require very low power to operate. Unfortunately, short light pulses (called solitons) cannot be properly generated in this material because of a property called dispersion, which causes light or other electromagnetic waves to travel at different speeds, depending on their frequency. ULL has what is known as normal dispersion, and this prevents waveguides made of ULL nitride from supporting the short pulses necessary for microcomb operation.

In a paper appearing in Nature Photonics (“Soliton pulse pairs at multiple colors in normal dispersion microresonators”), the researchers discuss their development of the new micro comb, which overcomes the inherent optical limitations of ULL nitride by generating pulses in pairs. This is a significant development because ULL nitride is created with the same technology used for manufacturing computer chips. This kind of manufacturing technique means that these microcombs could one day be integrated into a wide variety of handheld devices similar in form to smartphones.

The most distinctive feature of an ordinary microcomb is a small optical loop that looks a bit like a tiny racetrack. During operation, the solitons automatically form and circulate around it.

“However, when this loop is made of ULL nitride, the dispersion destabilizes the soliton pulses,” says co-author Zhiquan Yuan (MS ’21), a graduate student in applied physics.

Imagine the loop as a racetrack with cars. If some cars travel faster and some travel slower, then they will spread out as they circle the track instead of staying as a tight pack. Similarly, the normal dispersion of ULL means light pulses spread out in the microcomb waveguides, and the microcomb ceases to work.

The solution devised by the team was to create multiple racetracks, pairing them up so they look a bit like a figure eight. In the middle of that ‘8,’ the two tracks run parallel to each other with only a tiny gap between them.

Conjoined ‘racetracks’ make new optical devices possible, Nanowerk.

All-Solid-State Batteries

Often referred to as the “dream batteries,” all-solid-state batteries are the next generation of batteries that many battery manufacturers are competing to bring to market. Unlike lithium-ion batteries, which use a liquid electrolyte, all components, including the electrolyte, anode, and cathode, are solid, reducing the risk of explosion, and are in high demand in markets ranging from automobiles to energy storage systems (ESS).

However, devices that maintain the high pressure (10s of MPa) required for stable operation of all-solid-state batteries have problems that reduce the battery performance, such as energy density and capacity, and must be solved for commercialization.

Dr. Hun-Gi Jung and his team at the Energy Storage Research Center at the Korea Institute of Science and Technology (KIST) have identified degradation factors that cause rapid capacity degradation and shortened lifespan when operating all-solid-state batteries at pressures similar to those of lithium-ion batteries. The research is published in the journal Advanced Energy Materials.

Unlike previous studies, the researchers confirmed for the first time that degradation can occur inside the cathode as well as outside, showing that all-solid-state batteries can be operated reliably even in low-pressure environments.

In all-solid-state batteries, the cathode and anode have a volume change during repeated charging and discharging, resulting in interfacial degradation, such as side reaction and contact loss between active materials and solid electrolytes, which increase the interfacial resistance and worsen cell performance.

To solve this problem, external devices are used to maintain high pressure, but this has the disadvantage of reducing energy density as the weight and volume of the battery increase. Research is being conducted on the inside of the all-solid-state cell to maintain the performance of the cell, even in low-pressure environments.

Investigation of the degradation mechanism for all-solid-state batteries takes another step toward commercialization, National Research Council of Science and Technology.

The Red Road…

I can hear an irritated counterthrust already. The president has not driven the United States into a recession during his almost seven years in office. Unemployment stands at a respectable 4.6 percent. Well, fine. But the other side of the ledger groans with distress: a tax code that has become hideously biased in favor of the rich; a national debt that will probably have grown 70 percent by the time this president leaves Washington; a swelling cascade of mortgage defaults; a record near-$850 billion trade deficit; oil prices that are higher than they have ever been; and a dollar so weak that for an American to buy a cup of coffee in London or Paris—or even the Yukon—becomes a venture in high finance.

And it gets worse. After almost seven years of this president, the United States is less prepared than ever to face the future. We have not been educating enough engineers and scientists, people with the skills we will need to compete with China and India. We have not been investing in the kinds of basic research that made us the technological powerhouse of the late 20th century. And although the president now understands—or so he says—that we must begin to wean ourselves from oil and coal, we have become more deeply dependent on both on his watch.

Up to now, the conventional wisdom has been that Herbert Hoover, whose policies aggravated the Great Depression, is the odds-on claimant for the mantle of “worst president” regarding stewardship of the American economy. Once Franklin Roosevelt assumed office and reversed Hoover’s policies, the country began to recover. The economic effects of Bush’s presidency are more insidious than those of Hoover, harder to reverse, and likely to be longer-lasting. There is no threat of America’s being displaced from its position as the world’s richest economy. But our grandchildren will still be living with and struggling with the economic consequences of Mr. Bush.

The Economic Consequences of Mr. Bush, Joseph E. Stiglitz, Vanity Fair, December 7, 2007

I am enjoying the New York Times bestseller by former Congresswoman Liz Cheney, Oath and Honor: A Memoir and a Warning. The book was sold out, so I bought the CDs to play on my car’s player as I casually drive to and from work. There are 11 CDs, and from the few I’ve listened to, she has an hour’s worth of material for each. The book is 384 pages.

I enjoy her erudite writing and observations of our current moment and crisis. Though we probably don’t agree on many things, I admire her integrity, love of her parents (particularly her dad), her family, and demonstrated fidelity to the US Constitution.

However, her dad was a part of the administration that Nobel laureate Dr. Stiglitz discusses in his Vanity Fair article. It was her dad who, instead of searching for a VP candidate, nominated himself. It was her dad who championed the disastrous war in Iraq, a country that did not attack us on September 11, 2001. He didn’t just “sex up” the intelligence about weapons of mass destruction in Iraq; he lied. That license led to thousands of Iraqis killed and the fertile ground from which sprang Al-Qaeda in Iraq, followed by ISIS. That license led to pathological licentiousness to lie more than 30,000 times in a four-year presidential term. “Deficits don’t matter” leads to truth not mattering—Post hoc ergo proctor hoc.

It was her dad who said:

“You know, Paul, Reagan proved deficits don’t matter,” he said, according to excerpts. Cheney continued: “We won the midterms [congressional elections]. This is our due.” A month later, in December 2002, Cheney told the Treasury secretary he was fired.

O’Neill says Cheney told him, `Deficits don’t matter,’ Chicago Tribune, January 12, 2004

I remember reading this on my Kindle: The Price of Loyalty: George W. Bush, the White House, and the Education of Paul O’Neill, Ron Suskind. For Liz’s dad, deficits didn’t matter. That drove the drunken stupor of tax cuts that led to the cliff we almost fell off in 2008. There was a real crisis when the Obama-Biden administration took office after the financial crash spawned by the “deficits don’t matter” philosophy.

Wall Street was, of course, bailed out over Main Street. COVID bailouts benefitted the rich. That’s why Wall Street is more than willing to do it again. Until we see some CEOs and Hedge Fund Managers frog-marched in shackles, what onus stops them?

The Dow Jones hit a record 37,000+ Thursday. Yet, we’re into how we “feel” about the economy. I don’t think it’s “feelings.”

Inflation soared across the globe last year, peaking near 11% in the eurozone and above 9% in the US.

The source of that high inflation has become a well-trodden line. Analysts have typically laid the blame on supply-chain bottlenecks created by excess demand during the COVID-19 pandemic and exacerbated by Russia’s invasion of Ukraine.

The war also increased energy prices, leading to further rises in inflation as suppliers factored in higher transport and running costs.

While this contributed to rising prices, the report finds that company profits increased at a much faster rate than costs did, in a process often dubbed “greedflation.”

Profits for companies in some of the world’s largest economies rose by 30% between 2019 and 2022, significantly outpacing inflation, according to the group’s research of 1,350 firms across the US, the UK, Europe, Brazil, and South Africa.

The biggest perpetrators were energy companies like Shell, Exxon Mobil, and Chevron, which were able to enjoy massive profits last year as demand moved away from Russian oil and gas.

A June study by the International Monetary Fund (IMF) found that 45% of eurozone inflation in 2022 could be attributed to domestic profits. Companies in a position to benefit most from higher commodity prices and supply-demand mismatches raised their profits by the most, the study found.

CEOs of the world’s biggest companies consistently sounded the alarm on inflation as a significant barrier to growth. Many blamed rising input costs on their own price hikes. However, lots of those CEOs appear to have instead used the panic of rising costs to pump up their balance sheet.

The biggest study of ‘greedflation’ yet looked at 1,300 corporations to find many of them were lying to you about inflation, Ryan Hogg, Yahoo Finance, December 8, 2023

In essence, gaslighting is the psychological manipulation of a person, usually over an extended period of time, that causes the victim to question the validity of their own thoughts, perception of reality, or memories and typically leads to confusion, loss of confidence and self-esteem, uncertainty of one’s emotional or mental stability, and a dependency on the perpetrator—the act or practice of grossly misleading someone, especially for one’s own advantage. Election season can create emotions spanning from immense anxiety all the way to extreme apathy. The public arguing, divisiveness, and competition for votes, including political gaslighting, can be overwhelming and exhausting.—Vernita Perkins and Leonard A. Jason, Merriam-Webster.

Political gaslighting has one objective: to undermine the truth, or more accurately, to undermine objective truth.

“Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.” Winston Smith, in “1984” by George Orwell. Under torture, O’Brien makes Winston say he sees five fingers when O’Brien is holding up four. The Party was the arbiter of truth, and “truth” was whatever the Party or O’Brien said it was.

“There are FOUR lights!” Jean Luc Picard shouted defiantly under torture by Gul Madred in Star Trek: The Next Generation: “Chain of Command, part II.”

There are strategies to combat gaslighting. Despair can be debilitating and a self-fulfilling prophecy if the worst possible outcome that you can think of happens.

The best strategy I know to combat despair is to work on a campaign that you’re passionate about. In 2012, it didn’t look like Barack Obama and Joe Biden would get re-elected against Mitt Romney and Paul Ryan (former Speaker of the House – remember him?). My wife and I volunteered to call from the campaign office of Sean Patrick Maloney, who we had never heard of. He won and became our Congressman as long as we lived in New York. He sadly lost his seat when congressional districts were redrawn, so he was competing for the same votes as another Democrat.

The best weapon against gaslighting is truth.

Liz Cheney is telling the truth and bringing receipts—truth matters.

She quotes her dad on the second CD, who admonished her to “save the republic, daughter,” missing the irony his “deficits don’t matter” rhetoric spawned what we’re all living through.

Take heart. Tell the truth. Truth matters in the face of lies. Grind it out next year and vote.

Microlenses…

Using 3D printing and porous silicon, researchers at the University of Illinois Urbana-Champaign have developed compact, visible wavelength achromats that are essential for miniaturized and lightweight optics. These high-performance hybrid micro-optics achieve high focusing efficiencies while minimizing volume and thickness. Further, these microlenses can be constructed into arrays to form larger area images for achromatic light-field images and displays.

This study was led by materials science and engineering professors Paul Braun and David Cahill, electrical and computer engineering professor Lynford Goddard, and former graduate student Corey Richards. The results of this research were published in Nature Communications.

“We developed a way to create structures exhibiting the functionalities of classical compound optics but in highly miniaturized thin film via non-traditional fabrication approaches,” says Braun.

In many imaging applications, multiple wavelengths of light are present, e.g., white light. If a single lens is used to focus this light, different wavelengths focus at different points, resulting in a color-blurred image. To solve this problem, multiple lenses are stacked together to form an achromatic lens. “In white light imaging, if you use a single lens, you have considerable dispersion, and so each constituent color is focused at a different position. With an achromatic lens, however, all the colors focus at the same point,” says Braun.

The challenge, however, is that the required stack of lens elements required to make an achromatic lens is relatively thick, which can make a classical achromatic lens unsuitable for newer, scaled-down technological platforms, such as ultracompact visible wavelength cameras, portable microscopes, and even wearable devices.

French economist Thomas Piketty compares the US economy to Europe in the Gilded Age. Oregon Live, 2014

Topics: Civics, Civil Rights, Civilization, Climate Change, Democracy, Existentialism, Fascism

Thomas Piketty wrote “Capital in the 21st Century” in 2013 centered on the wealth inequality we can see all around us. I can see more house-less citizens on the streets of North Carolina and Texas (on a recent visit) than I can remember from my youth because back then, we didn’t have 8 billion inhabitants on the planet. There is a documentary of the same title on Amazon Prime video. The premise is ominous, and it bears witness to the stress that our world system is undergoing.

Dr. Piketty suggests that the rise of fascism around the world is because of income inequality. The climate crisis only exacerbates the supply chain, as thousand-year weather events are now more frequent than we would like.

Fascism is on the rise globally, but it is for lazy people. Propping up a so-called “strongman” gives a fall guy: if he (usually a “he”) is right, he gets all the praise. If he’s wrong, there can be one of two reactions: a coup (a coup, political, physical, or both is usually how they came to power in the first place), or a flaccid, impotent collective powerless shrug by the populace. So-called “strongmen” (an ever-oxymoron) are preferred when there is uncertainty, supplies are scarce, and people are fleeing wars, biblical tsunamis, and isolated by pandemics. When people are afraid, they are ripe for conmen and charlatans who will “fix” what is wrong and reflect back to halcyon days that never existed.

Democracy requires a shared reality, upon which sides debate and come to a consensus for the betterment of the electorate. Consensus means that you and your side won’t get your “laundry list” after laying out your arguments, at least in that particular debate. It requires compromise and logic to be successful. It also helps that you are sane.

Whether you set your government framework on capitalism, communism, republicanism, or socialism, the divine right of kings, each has a hierarchy decided long ago of those who deserve the wealth and riches, and those pariahs at the base of the pyramid that do not.

Russian aggression in Ukraine, Hamas attacks in Israel; and Somali refugees in Europe are all because we are on the same volume of a planet that existed 43 years ago when we were only 4.4 billion people, and the American military after Vietnam was licking its wounds, reframing around an “all-volunteer force.” The Soviet Union still existed as an existential boogie-man. Now, that remnant interferes in democratic elections worldwide, because the notion of participation in a stable world order is anathema to a kleptocracy.

Modern-day robber barons are no different than their ancestors, who met untimely ends in the French Revolution. Since we fought a Revolutionary War to depart the authoritarian crown of King George, the word sounds adventurous, avant-garde; “cool.” Revolutions are bloody, and they aren’t always for noble reasons.

“We tolerate no one in our ranks who attacks the ideas of Christianity. Our movement is Christian.” Adolph Hitler, 1928, Snopes

The current status quo is unsustainable. We can’t keep siphoning up (“trickledown” is gaslighting) tax breaks to American oligarchs and tax shelters in America and Europe for Russian oligarchs. It is thermodynamically impossible to “consume our way to utopia,” and colonizing Mars is a pipedream by Elmo Musk, whose plan to terraform the Red Planet is impractical, impossible, unworkable, and dangerous. I’m not against space exploration. Far from it. Seeing the runaway Greenhouse Gas Emissions on Venus informed our models on Earth. Mars at one time probably had an atmosphere, water, and life about four billion years ago. The point is, the planet doesn’t have either now, and the closest planet to terraform is right under our feet, without a requirement of VTOL (vertical takeoff and landing), rockets, or superluminal star drives. It merely requires something we should have learned to do in kindergarten: sharing resources with one another for the “common good” of continuance.

Cooperation is survival. Hoarding is death.

“Last year, I had a life-changing experience at 90 years old. I went to space, after decades of playing an iconic science-fiction character who was exploring the universe. I thought I would experience a deep connection with the immensity around us, a deep call for endless exploration.

“I was absolutely wrong. The strongest feeling, that dominated everything else by far, was the deepest grief that I had ever experienced.

“I understood, in the clearest possible way, that we were living on a tiny oasis of life, surrounded by an immensity of death. I didn’t see infinite possibilities of worlds to explore, adventures to have, or living creatures to connect with. I saw the deepest darkness I could have ever imagined, contrasting so starkly with the welcoming warmth of our nurturing home planet.

“This was an immensely powerful awakening for me. It filled me with sadness. I realized that we had spent decades, if not centuries, being obsessed with looking away, with looking outside. I did my share in popularizing the idea that space was the final frontier. But I had to get to space to understand that Earth is and will stay our only home. And that we have been ravaging it, relentlessly, making it uninhabitable.”

Researchers at Tufts University and Harvard University’s Wyss Institute have created tiny biological robots that they call Anthrobots from human tracheal cells that can move across a surface and have been found to encourage the growth of neurons across a region of damage in a lab dish.

The multicellular robots, ranging in size from the width of a human hair to the point of a sharpened pencil, were made to self-assemble and shown to have a remarkable healing effect on other cells. The discovery is a starting point for the researchers’ vision to use patient-derived biobots as new therapeutic tools for regeneration, healing, and treatment of disease.

The work follows from earlier research in the laboratories of Michael Levin, Vannevar Bush Professor of Biology at Tufts University School of Arts & Sciences, and Josh Bongard at the University of Vermont in which they created multicellular biological robots from frog embryo cells called Xenobots, capable of navigating passageways, collecting material, recording information, healing themselves from injury, and even replicating for a few cycles on their own.

At the time, researchers did not know if these capabilities were dependent on their being derived from an amphibian embryo, or if biobots could be constructed from cells of other species.

In the current study, published in Advanced Science, Levin, along with Ph.D. student Gizem Gumuskaya discovered that bots can in fact be created from adult human cells without any genetic modification and they are demonstrating some capabilities beyond what was observed with the Xenobots.

The discovery starts to answer a broader question that the lab has posed—what are the rules that govern how cells assemble and work together in the body, and can the cells be taken out of their natural context and recombined into different “body plans” to carry out other functions by design?

Quantum scientists have discovered a rare phenomenon that could hold the key to creating a ‘perfect switch’ in quantum devices, which flips between being an insulator and a superconductor.

The research, led by the University of Bristol and published in Science, found these two opposing electronic states exist within purple bronze, a unique one-dimensional metal composed of individual conducting chains of atoms.

Tiny changes in the material, for instance, prompted by a small stimulus like heat or light, may trigger an instant transition from an insulating state with zero conductivity to a superconductor with unlimited conductivity and vice versa. This polarized versatility, known as “emergent symmetry,” has the potential to offer an ideal On/Off switch in future quantum technology developments.

Lead author Nigel Hussey, Professor of Physics at the University of Bristol, said, “It’s a really exciting discovery that could provide a perfect switch for quantum devices of tomorrow.

“The remarkable journey started 13 years ago in my lab when two Ph.D. students, Xiaofeng Xu, and Nick Wakeham, measured the magnetoresistance—the change in resistance caused by a magnetic field—of purple bronze.”

In the absence of a magnetic field, the resistance of purple bronze was highly dependent on the direction in which the electrical current was introduced. Its temperature dependence was also rather complicated. Around room temperature, the resistance is metallic, but as the temperature is lowered, this reverses and the material appears to be turning into an insulator. Then, at the lowest temperatures, the resistance plummets again as it transitions into a superconductor.

Despite this complexity, surprisingly, the magnetoresistance was found to be extremely simple. It was essentially the same irrespective of the direction in which the current or field was aligned and followed a perfect linear temperature dependence all the way from room temperature down to the superconducting transition temperature.
