Cloth Diapers…

This essay is derived from a creative work of the same title, posted on my poetry blog Monday.

Happy birthday, mom. I miss you.

Sixty years ago, you were thirty-eight years old. I was one year, one month, and one day old. I was apparently potty-trained, which I didn’t know until my big sister told me after I bragged that my granddaughter, your great-granddaughter, was potty-trained at two.

“We had cloth diapers back then. No one was playing with you, Reggie.”

I took this to mean the task of changing cloth diapers, flushing the load, and WASHING them was probably unpleasant. It also subtly suggests that disposable diapers stifle our development.

Twenty-two years ago this past Monday, a Saudi Sheik, Osama Bin Ladin, trained by the CIA when he was in the Mujahadeen, fighting a proxy war with Russia in Afghanistan, convinced 19 hijackers, 15 from his nation, to plunge top-filled planes into the Twin Towers, the Pentagon: Flight 93 was supposed to hit the Capitol, except for the passengers who decided to intervene, “let’s roll.” 3,000+ people died. The nation was terrorized.

On your birthday, four little black girls were murdered for the crime of singing in a choir, or, correction, PRACTICING to sing in a choir for a performance. It happened on your thirty-eighth birthday. It was a Sunday.

Monday, you and Pop had to go to work like it was “normal.” Violence has been normal for African Americans since the 13th Amendment ended enslavement (EXCEPT as a punishment for a crime: “wiggle room” that has been abused), the 14th gave us birthright citizenship, and the 15th gave at least our men, the right to vote. That was immediately thwarted in the aftermath of the antebellum South by naming the number of coins/marbles/soap bubbles in a bottle, poll taxes, tests to recite The Constitution (when civics knowledge for the average citizen – then, and now – would likely fail miserably).

You both had to drop me off at the sitter and hope to see me alive again and pretend, like every black person at the time, that this was “normal.”

“Two medical professionals, Dr. Elizabeth H. Blackburn and Dr. Carol W. Greider,
Shared the Nobel Prize in Physiology and Medicine with Dr. Jack W. Szostak in 2009 “for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase.”

“The long, thread-like DNA molecules that carry our genes are packed into chromosomes, the telomeres being the caps on their ends. Elizabeth Blackburn and Jack Szostak discovered that a unique DNA sequence in the telomeres protects the chromosomes from degradation. Carol Greider and Elizabeth Blackburn identified telomerase, the enzyme that makes telomere DNA. These discoveries explained how the ends of the chromosomes are protected by the telomeres and that they are built by telomerase.

“If the telomeres are shortened, cells age. Conversely, if telomerase activity is high, telomere length is maintained, and cellular senescence is delayed.”

Telomeres are shorter for African Americans, a byproduct of 400 years of racial terrorism.

We were, and are, terrorized for being human, for wanting what’s in The Constitution, for exercising our birthright citizenship. They want to take that away, too., for undocumented immigrants, then probably selective brown people who won’t vote for them. The Growth and Opportunity Project said they should reach out to African Americans, Asian Americans, Hispanic/Latino Americans, the LGBT, Women, and Youth to expand the party. They instead engage in “culture wars” that are silly, like fighting the banning of gas stoves (there isn’t one), the replacement of incandescent lights with more climate-friendly fluorescent or LED lights, and somehow, it’s outrageous to suggest limiting beer consumption (no one did).

I’m tired, momma.

September 11, 2001, Pop had been dead for two years. The boys were in fourth grade and college. They had questions. I had no answers, and I wanted to talk to Pop, but I couldn’t. Now I can’t talk to you.

As Americans finally experienced, on September 11, 2001, the psychological effects of the horrific fear of not knowing what calamity would end your existence.

Living in fear of being killed for the “sin” of being alive shortens your telomeres.

As my big sister observed:
This country needs more cloth diapers for our development.

Happy Heavenly birthday, momma. I miss you. Love, “Stink.”

Pines’ Demon…

Lurking for decades: researchers have discovered Pines’ demon, a collection of electrons in a metal that behaves like a massless wave. It is illustrated here as an artist’s impression. (Courtesy: The Grainger College of Engineering/University of Illinois Urbana-Champaign)

For nearly seven decades, a plasmon known as Pines’ demon has remained a purely hypothetical feature of solid-state systems. Massless, neutral, and unable to interact with light, this unusual quasiparticle is reckoned to play a key role in certain superconductors and semimetals. Now, scientists in the US and Japan say they have finally detected it while using specialized electron spectroscopy to study the material strontium ruthenate.

Plasmons were proposed by the physicists David Pines and David Bohm in 1952 as quanta of collective electron density fluctuations in a plasma. They are analogous to phonons, which are quanta of sound, but unlike phonons, their frequency does not tend to zero when they have no momentum. That’s because finite energy is needed to overcome the Coulomb attraction between electrons and ions in a plasma in order to get oscillations going, which entails a finite oscillation frequency (at zero momentum).

Today, plasmons are routinely studied in metals and semiconductors, which have conduction electrons that behave like a plasma. Plasmons, phonons, and other quantized fluctuations are called quasiparticles because they share properties with fundamental particles such as photons.

In 1956, Pines hypothesized the existence of a plasmon which, like sound, would require no initial burst of energy. He dubbed the new quasiparticle a demon in honor of James Clerk Maxwell’s famous thermodynamic demon. Pines’ demon forms when electrons in different bands of metal move out of phase with one another such that they keep the overall charge static. In effect, a demon is the collective motion of neutral quasiparticles whose charge is screened by electrons from another band.

Demon quasiparticle is detected 67 years after it was first proposed. Edwin Cartlidg, Physics World.

Polluting the Pristine…

Antarctica is often described as one of the most pristine places in the world, but it has a dirty secret. Parts of the sea floor near Australia’s Casey research station are as polluted as the harbor in Rio de Janeiro, Brazil, according to a study published in PLoS ONE in August.

The contamination is likely to be widespread across Antarctica’s older research stations, says study co-author Jonathan Stark, a marine ecologist at the Australian Antarctic Division in Hobart. “These contaminants accumulate over long time frames and don’t just go away,” he says.

Stark and his colleagues found high concentrations of hydrocarbons — compounds found in fuels — and heavy metals, such as lead, copper, and zinc. Many of the samples were also loaded with polychlorinated biphenyls, highly carcinogenic chemical compounds that were common before their international ban in 2001.

When the researchers compared some of the samples with data from the World Harbor Project — an international collaboration that tracks large urban waterways — they found that lead, copper, and zinc levels in some cases were similar to those seen in parts of Sydney Harbour and Rio de Janeiro over the past two decades.

Widespread pollution

The problem of pollution is not unique to Casey station, says Ceisha Poirot, manager of policy, environment, and safety at Antarctica New Zealand in Christchurch. “All national programs are dealing with this issue,” she says. At New Zealand’s Scott Base — which is being redeveloped — contamination left from past fuel spills and poor waste management has been detected in soil and marine sediments. More of this historical pollution will emerge as the climate warms, says Poirot. “Things that were once frozen in the soil are now becoming more mobile,” she says.

Most of Antarctica’s contamination is due to historically poor waste management. In the old days, waste was often just dumped a small distance from research stations, says Terence Palmer, a marine scientist at Texas A&M University–Corpus Christi.

Research stations started to get serious about cleaning up their act in 1991. In that year, an international agreement known as the Protocol on Environmental Protection to the Antarctic Treaty, or the Madrid Protocol, was adopted. This designated Antarctica as a “natural reserve, devoted to peace and science,” and directed nations to monitor environmental impacts related to their activities. But much of the damage had already been done — roughly two-thirds of Antarctic research stations were built before 1991.

Quantum Slow Down…

Topics: Chemistry, Computer Science, Quantum Computer, Quantum Mechanics

Scientists at the University of Sydney have, for the first time, used a quantum computer to engineer and directly observe a process critical in chemical reactions by slowing it down by a factor of 100 billion times.

Joint lead researcher and Ph.D. student Vanessa Olaya Agudelo said, “It is by understanding these basic processes inside and between molecules that we can open up a new world of possibilities in materials science, drug design, or solar energy harvesting.

“It could also help improve other processes that rely on molecules interacting with light, such as how smog is created or how the ozone layer is damaged.”

Specifically, the research team witnessed the interference pattern of a single atom caused by a common geometric structure in chemistry called a “conical intersection.”

Conical intersections are known throughout chemistry and are vital to rapid photochemical processes such as light harvesting in human vision or photosynthesis.

Chemists have tried to directly observe such geometric processes in chemical dynamics since the 1950s, but it is not feasible to observe them directly, given the extremely rapid timescales involved.

To get around this problem, quantum researchers in the School of Physics and the School of Chemistry created an experiment using a trapped-ion quantum computer in a completely new way. This allowed them to design and map this very complicated problem onto a relatively small quantum device—and then slow the process down by a factor of 100 billion. Their research findings are published August 28 in Nature Chemistry.

“In nature, the whole process is over within femtoseconds,” said Olaya Agudelo from the School of Chemistry. “That’s a billionth of a millionth—or one quadrillionth—of a second.

“Using our quantum computer, we built a system that allowed us to slow down the chemical dynamics from femtoseconds to milliseconds. This allowed us to make meaningful observations and measurements.

“This has never been done before.”

Joint lead author Dr. Christophe Valahu from the School of Physics said, “Until now, we have been unable to directly observe the dynamics of ‘geometric phase’; it happens too fast to probe experimentally.

“Using quantum technologies, we have addressed this problem.”

Astronomers are racing to explain peculiar orbits of faraway objects at the edge of our solar system.

Among the many mysteries that make the furthest reaches of our solar system, well, mysterious, is the exceptionally egg-shaped path of a dwarf planet called 90377 Sedna.

Its 11,400-year orbit, one of the longest of any resident of the solar system, ushers the dwarf planet to seven billion miles (11.3 billion km) from the sun, then escorts it out of the solar system and way past the Kuiper Belt to 87 billion miles (140 billion km), and finally takes it within a loose shell of icy objects known as the Oort cloud. Since Sedna’s discovery in 2003, astronomers have struggled to explain how such a world could have formed in a seemingly empty region of space, where it is too far to be influenced by giant planets of the solar system and even the Milky Way galaxy itself.

Now, a new study suggests that a thus far undetected Earth-like planet hovering in that region could be deviating orbits of Sedna and a handful of similar trans-Neptunian objects (TNOs), which are the countless icy bodies orbiting the sun at gigantic distances. Many TNOs have oddly inclined and egg-shaped orbits, possibly due to being tugged at by a hidden planet, astronomers say.

60 Years Ago Tomorrow…

Sixty years ago tomorrow, two dear friends turned a year old, and ten years old. Sixty years ago tomorrow, I was a year, and 12 days old. The March on Washington happened on the eighth anniversary of the terrorism and slaying of Emmett Till, August 28, 1955, the actual date of original march August 28, 1963, this coming Monday. The demonstrators asked for a form of reparations that would come in the Civil Rights Bill in 1964 the next year, the Voting Rights Bill in 1965, and the Fair Housing Act in 1968. Dr. King, in a recording before the march opined that “we were coming to get our check.” There were celebrities like Harry Belafonte, Sidney Poitier, Marlon Brando, and future politicos (on opposite sides now) Nancy Pelosi, and Mitch McConnell. The march was a sea of “diversity, equity (sought) and inclusion (goaled for)” in that there were African Americans, white Americans, Jews, women and other minority groups on the Washington Mall. It was the “future and the hope” Gene Roddenberry and Lucille Ball launched Star Trek from. In two hundred years, we will have to get something right about living together.

At the original march, there were very few, if any, women allowed on the platform, John Lewis and Dr. King being the most famously remembered, as the Civil Rights Movement had a notable flaw: it was misogynist to its core. A lot of work behind the scenes, the arrests, the enduring of fire hoses was done by women like my big sister, heretofore unacknowledged. The hierarchy the then young people were marching against was a justification for those who “had,” and those who “had not,” but that did not let women at Langston’s table yet. This stratification is a competition for resources, and those who have had the resources are never eager to part with or share them, even if it insures species survival. It makes “trickledown” a gaslighting myth, as any distribution, regardless of speed, is anathema to the system.

Tomorrow, there will be a commemorative march populated by the “least of these”: African Americans, Asians, Hispanic/Latinos, LGBTQ, Women: all whose constitutional rights as citizens and EXISTENCE as humanity has been challenged since August 28, 1963. There has been a sustained assault by the ones who have benefited the most from the hierarchy that established Levittown’s that are more economically segregated (de facto) than de jure (by law). No one has to burn crosses on your front lawn if you can’t afford to live there. All of the aforementioned groups have seen the Voting Rights Act gutted, Roe vs. Wade eliminated, bodily autonomy and privacy of what we as citizens do at home in our bedrooms, down to contraception itself for the same reason: the hoarding of resources by those who consider themselves “worthy” so long as they have pariahs’ necks to stamp.

Broadly defined, ecofascism is any environmentalism that advocates or accepts violence and does so in a way that reinforces existing systems of inequality or targets certain people while leaving others untouched. It is basically environmentalism that suggests that certain people are naturally and exclusively entitled to control and enjoy environmental resources. Some types of people, in other words, are “native species” and others are “invasive.”

The term itself is still very much up for debate but gathering currency largely due to high-profile individuals who have explicitly identified themselves as ecofascist. An example includes the man who murdered 51 People in a Christchurch, New Zealand, mosque in 2019. The El Paso, Texas, shooter, also in 2019, did not refer to himself as an ecofascist, but he plagiarized the Christchurch shooter’s manifesto, including many of its bogus arguments about race, nation, and environment. More recently, as you mentioned, another young man drove several hours to Buffalo, New York, where he targeted Black grocery shoppers.

A common ecofascist argument, then, links national environment to population, contending that certain (often specifically nonwhite) populations, within the US or beyond it, are the primary cause of climate change and other environmental issues.

I would also call this “eco-eugenics.”

Environment. Levittown. Wealth. Population. All determined by a sick, psychopathy. Divided like a pie on the table of the depraved, in this case, the pariah Lazarus, and his kin get no crumbs from the Koinonia table. When you found a nation on the land grab and murder of its indigenous inhabitants, from Columbus to “Manifest Destiny,” when you cultivate and build your wealth on the backs of kidnapped enslaved people from the continent that BIRTHED humanity, the only way you can maintain such a system that would make Alfred Hitchcock BLUSH is through the application of unmerciful violence. “Christian nation” and “United States” become a form of delusion and self-gaslighting. You might have to ban a few books to keep up the façade. Burning them would be too obvious.

I don’t know what the world will be in 200 years, just like I don’t know if a Zephram Cochrane will ever exist, but I hope for my “little one’s” sake in six decades, it is still here, balanced on indigenous sensibilities with the environment, more egalitarian, and less authoritarian, the inequity quelled and every stomach filled, including hers, sixty years from now. She will be a little older than me, hopefully in a better world that I helped form.

Stronger Than Steel…

Researchers from the University of Connecticut and colleagues have created a highly durable, lightweight material by structuring DNA and then coating it in glass. The resulting product, characterized by its nanolattice structure, exhibits a unique combination of strength and low density, making it potentially useful in applications like vehicle manufacturing and body armor. (Artist’s concept.)

Researchers have developed a highly robust material with an extremely low density by constructing a structure using DNA and subsequently coating it in glass.

Materials possessing both strength and lightness have the potential to enhance everything from automobiles to body armor. But usually, the two qualities are mutually exclusive. However, researchers at the University of Connecticut, along with their collaborators, have now crafted an incredibly strong yet lightweight material. Surprisingly, they achieved this using two unexpected building blocks: DNA and glass.

“For the given density, our material is the strongest known,” says Seok-Woo Lee, a materials scientist at UConn. Lee and colleagues from UConn, Columbia University, and Brookhaven National Lab reported the details on July 19 in Cell Reports Physical Science.

Strength is relative. Iron, for example, can take 7 tons of pressure per square centimeter. But it’s also very dense and heavy, weighing 7.8 grams/cubic centimeter. Other metals, such as titanium, are stronger and lighter than iron. And certain alloys combining multiple elements are even stronger. Strong, lightweight materials have allowed for lightweight body armor and better medical devices and made safer, faster cars and airplanes.

Build Better Batteries…

The demand for high-performance batteries, especially for use in electric vehicles, is surging as the world shifts its energy consumption to a more electric-powered system, reducing reliance on fossil fuels and prioritizing climate remediation efforts. To improve battery performance and production, Penn State researchers and collaborators have developed a new fabrication approach that could make for more efficient batteries that maintain energy and power levels.

The improved method for fabricating battery electrodes may lead to high-performance batteries that would enable more energy-efficient electric vehicles, as well as such benefits as enhancing power grid storage, according to Hongtao Sun. Sun is an assistant professor of industrial and manufacturing engineering at Penn State and the co-corresponding author of the study, which was published in and featured on the front cover of Carbon.

“With current batteries, we want them to enable us to drive a car for longer distances, and we want to charge the car in maybe five minutes, 10 minutes, comparable to the time it takes to fill up for gas,” Sun said. “In our work, we considered how we can achieve this by making the electrodes and battery cells more compact, with a higher percentage of active components and a lower percentage of passive components.”

If an electric car maker wants to improve the driving distance of their vehicles, they add more battery cells, numbering in the thousands. The smaller and lighter, the better, according to Sun.

“The solution for longer driving distances for an electric vehicle is just to add compact batteries, but with denser and thicker electrodes,” Sun said, explaining that such electrodes could better connect and power the battery’s components, making them more active. “Although this approach may slightly reduce battery performance per electrode weight, it significantly enhances the vehicle’s overall performance by reducing the battery package’s weight and the energy required to move the electric vehicle.”

According to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York, July 2023 was hotter than any other month in the global temperature record.

“Since day one, President Biden has treated the climate crisis as the existential threat of our time,” said Ali Zaidi, White House National Climate Advisor. Against the backdrop of record-high temperatures, wildfires, and floods, NASA’s analysis puts into context the urgency of President Biden’s unprecedented climate leadership. From securing the Inflation Reduction Act, the largest climate investment in history, to invoking the Defense Production Act to supercharge domestic clean energy manufacturing, to strengthening climate resilience in communities nationwide, President Biden is delivering on the most ambitious climate agenda in history.”

Overall, July 2023 was 0.43 degrees Fahrenheit (F) (0.24 degrees Celsius (C)) warmer than any other July in NASA’s record, and it was 2.1 F (1.18 C) warmer than the average July between 1951 and 1980. The primary focus of the GISS analysis is long-term temperature changes over many decades and centuries, and a fixed base period yields anomalies that are consistent over time. Temperature “normals” are defined by several decades or more – typically 30 years.

A group of researchers at the University of Illinois Urbana-Champaign demonstrated a way to use the renewable energy source of electricity to recycle a form of plastic that’s growing in use but more challenging to recycle than other popular forms of plastic.

In their study recently published in Nature Communications, they share their innovative process that shows the potential for harnessing renewable energy sources in the shift toward a circular plastics economy.

“We wanted to demonstrate this concept of bringing together renewable energy and a circular plastic economy,” said Yuting Zhou, a postdoctoral associate, and co-author, who worked on this groundbreaking research with two professors in chemistry at Illinois, polymer expert Jeffrey Moore and electrochemistry expert Joaquín Rodríguez-López.

The project was conceived by Moore, who had experience working with Poly(phthalaldehyde), a form of polyacetal. Polyoxymethylene (POM) is a high-performance acetal resin that is used in a variety of industries, including automobiles and electronics. A thermoplastic, it can be shaped and molded when heated and hardens upon cooling with a high degree of strength and rigidity, making it an attractive lighter alternative to metal in some applications, like mechanical gears in automobiles. It is produced by various chemical firms with slightly different formulas and names, including Delrin by DuPont.

When recycling, those highly crystalline properties of POM make it difficult to break down. It can be melted and molded again, but POM’s original material properties are lost, limiting the usefulness of the recycled material.

“When the polymer was in use as a product, it was not a pure polymer. It will also have other chemicals like coloring additives and antioxidants. So, if you simply melt it and remold it, the material properties are always lost,” Zhou explained.

The Illinois research team’s method uses electricity, which can be drawn from renewable sources, and takes place at room temperature.

This electro-mediated process deconstructs the polymer, breaking it down into monomers—the molecules that are bonded to other identical molecules to form polymers.

A recycling study demonstrates new possibilities for a circular plastics economy powered by renewable energy, Tracy Crane, University of Illinois at Urbana-Champaign.
