A new method for 3D printing, described in Science, makes inroads into hydrogel-based adhesives for use in medicine.

3D printers, which deposit individual layers of a variety of materials, enable researchers to create complex shapes and structures. Medical applications often require strong and stretchable biomaterials that also stick to moving tissues, such as the beating human heart or tough cartilage covering the surfaces of bones at a joint.

Many researchers are pursuing 3D-printed tissues, organs and implants created using biomaterials called hydrogels, which are made from networks of crosslinked polymer chains. While significant progress has been made in the field of fabricated hydrogels, traditional 3D printed hydrogels may break when stretched or crack under pressure. Others are too stiff to sculpt around deformable tissues.

Researchers at the University of Colorado Boulder, in collaboration with the University of Pennsylvania and the National Institutes of Standards and Technology (NIST), realized that they could incorporate intertwined chains of molecules to make 3D printed hydrogels stronger and more elastic – and possibly even allow them to stick to wet tissue. The method, known as CLEAR, sets an object’s shape using spatial light illumination (photopolymerization) while a complementary redox reaction (dark polymerization) gradually yields a high concentration of entangled polymer chains.

U.S. Senators and Representatives whose family had a history of enslaving others have greater present-day wealth.

Members of the U.S. congress whose ancestors enslaved people have had a higher median net worth than those whose ancestors did not, according to a new analysis published on Wednesday in PLOS ONE.

The analysis used genealogical data published last year by an investigative team at Reuters, which found that in 2021, at least 100 members of Congress were descended from enslavers. This included 8 percent of Democrats and 28 percent of Republicans.

This reporting caught the eye of Neil K. R. Sehgal, a Ph.D. student and computational social science researcher at the University of Pennsylvania. He wondered what this unique genealogical data might reveal when combined with other publicly available information about members of Congress—particularly their financial disclosure forms.

“Just the fact that this was available—this detailed genealogical data and these financial disclosures for members of Congress—allowed us to explore this link,” Sehgal says.

The racial wealth gap in the U.S. is staggering. More than one in five white households have a net worth of more than $1 million, whereas more than one in five Black households have zero or negative net worth. This extreme imbalance began with slavery and has been perpetuated by racist policies and practices in housing, education, hiring, voting, and more that prevent many Black Americans from attaining and passing on generational wealth.

"The Secret Life of the Universe" by Dr. Nathalie Cabrol, the SETI Institute's chief scientist and Director of the Carl Sagan Center at the SETI Institute, is coming out this week, both in the US (August 13, 2024) and in the UK (August 15, 2024). Scriber/Simon & Schuster publishes both editions. Cabrol articulates an overview of where we stand today in our search for life in the universe, what's coming, and how looking out for life beyond Earth teaches us about our place on our planet.

Here is an excerpt to inspire you:

On July 11, 2022, the James Webb Space Telescope (JWST) returned its first images, penetrating the wall of time to show us the universe just a few hundred million years after its formation. In a marvelous cosmic irony, this immersion into the depths of our origins propels us into the future, where a revolution looms large in astronomy, in cosmology, and in astrobiology—the search for life in the universe. JWST comes after a few decades of space and planetary exploration during which we have discovered countless habitable environments in our solar system—for (simple) life as we know it, but also thousands of exoplanets in our galaxy, some of them located in the habitable zone of their parent stars.

We are living in a golden age in astrobiology, the beginning of a fantastic odyssey in which much remains to be written, but where our first steps bring the promise of prodigious discoveries. And these first steps have already transformed our species in one generation in a way that we cannot foresee just yet.

Copernicus taught us long ago that the Earth was neither at the center of the universe nor the center of the solar system, for that matter. We also learned from the work of Harlow Shapley and Henrietta Swan Leavitt that the solar system does not even occupy any particularly prominent place in our galaxy. It is simply tucked away at the inner edge of Orion’s spur in the Milky Way, 27,000 light-years from its center, in a galactic suburb of sorts. Our sun is an average-sized star located in a galaxy propelled at 2.1 million kilometers per hour in a visible universe that counts maybe 125 billion such cosmic islands, give or take a few billion. In this immensity, the Kepler mission taught us that planetary systems are the rule, not the exception.

This is how, in a mere quarter of a century, we found ourselves exploring a universe populated by as many planets as stars. Yet, looking up and far into what seems to be an infinite ocean of possibilities, the only echoes we have received so far from our explorations have been barren planetary landscapes and thundering silence. Could it be that we are the only guests at the universal table? Maybe. As a scientist, I cannot wholly discount this hypothesis, but it seems very unlikely and “an awful waste of space,” and for more than one reason.

EVIL STREAMING SERIES REVIEW

By Jarvis Sheffield

Evil is an outstanding series that masterfully blends supernatural elements with psychological drama, creating a viewing experience that is both thrilling and thought-provoking. The show stands out for its originality in both storytelling and character development, making it a refreshing addition to the genre. The narrative is artfully crafted, weaving together complex themes of faith, science, and the unknown, which keeps viewers hooked from the very first episode.

One of the most compelling aspects of Evil is the stellar performances by the cast, with Mike Colter leading the way as David Acosta. Colter's portrayal is nothing short of exceptional. He brings a deep sense of gravitas to the role, balancing strength and vulnerability in a way that makes his character incredibly relatable and engaging. His performance adds a layer of depth to the series that elevates it beyond typical supernatural dramas.

The supporting cast also delivers remarkable performances, each adding their unique touch to the show. Together, they create a dynamic ensemble that enhances the overall impact of the series. The chemistry among the actors is palpable, making their interactions feel genuine and compelling. 

The show’s ability to explore dark and complex themes while maintaining a sense of mystery and intrigue is what makes Evil truly special. It challenges viewers to think deeply while still delivering plenty of suspense and entertainment. If you are looking for a series that is both intellectually stimulating and genuinely entertaining, Evil is a must-watch.

Experiments on the Fermi–Hubbard model can now be made much larger, more uniform, and more quantitative.

A universal quantum computer—capable of crunching the numbers of any complex problem posed to it—is still a work in progress. But for specific problems in quantum physics, there’s a more direct approach to quantum simulation: Design a system that captures the physics you want to study, and then watch what it does. One of the systems most widely studied that way is the Fermi–Hubbard model (FHM), in which spin-up and spin-down fermions can hop among discrete sites in a lattice. Originally conceived as a stripped-down description of electrons in a solid, the FHM has attracted attention for its possible connection to the mysterious physics of high-temperature superconductivity.

Stripped down, though it may be, the FHM defies solution, either analytical or numerical, except in the simplest cases, so researchers have taken to studying it experimentally. In 2017, Harvard University’s Markus Greiner and colleagues made a splash when they observed antiferromagnetic order—a checkerboard pattern of up and down spins—in their FHM experiment consisting of fermionic atoms in a 2D lattice of 80 optical traps. (See Physics Today, August 2017, page 17.) The high-temperature-superconductor phase diagram has an antiferromagnetic phase near the superconducting one, so the achievement promised more exciting results to come. But the small size of the experiment limited the observations the researchers could make.

Mechanical watches and clockwork toys might seem like relics of a bygone age, but scientists in the US and Japan are bringing this old-fashioned form of energy storage into the modern era. By making single-walled carbon nanotubes (SWCNTs) into ropes and twisting them like the string on an overworked yo-yo, Katsumi Kaneko, Sanjeev Kumar Ujjain , and colleagues showed that they can store twice as much energy per unit mass as the best commercial lithium-ion batteries. The nanotube ropes are also stable at a wide range of temperatures, and the team says they could be safer than batteries for powering devices such as medical sensors.

SWCNTs are made from sheets of pure carbon just one atom thick that have been rolled into a straw-like tube. They are impressively tough – five times stiffer and 100 times stronger than steel – and earlier theoretical studies by team member David Tománek and others suggested that twisting them could be a viable means of storing large amounts of energy in a compact, lightweight system.

Each week, Quanta Magazine explains one of the most important ideas driving modern research. This week, physics staff writer Charlie Wood explains why many researchers are looking to outer space for signs of “new physics.”

Fundamental physics has a problem. Some researchers say the field faces a “nightmare scenario.” Some say it’s “in crisis.” To others, it’s merely “stuck.” Whatever word they use, most particle physicists acknowledge that progress has slowed. After a rip-roaring 20th century that saw the discovery of general relativity, quantum theory, and a dozen or so fundamental particles, the first quarter of the 21st century has mainly brought further confirmation of those theories.

Physicists know their hard-won understanding of nature’s laws is incomplete. They don’t know why certain particles have mass, what sort of invisible stuff seems to be holding galaxies together, or what sort of energy is driving the universe’s expansion. But their biggest blind spot is one of scale. Physicists have equations that predict how molecules zig and zag, how atoms split, and how the heart of the atom holds together. They can continue zooming into the sub-sub-subatomic world for quite a while, but eventually — for any event playing out on a stage roughly 10⁻³⁵ meters across — they run out of equations. The universe seems to have rules that tell it what to do in those situations (it follows them during black hole formation, for instance), but physicists are ignorant of these instructions.

Particle physicists have pushed their frontier of ignorance back to this minuscule realm by repeatedly crashing particles closer and closer together, watching what happens, and developing the mathematics to capture the strange and surprising behaviors they witness. This strategy has culminated in Europe’s Large Hadron Collider, a 27-kilometer ring that can summon the energies needed to collide protons and study nature at 10⁻¹⁹ meters. The international physics community aims to build a next-generation collider — perhaps with a 100-kilometer circumference — this century. But the money, time and technology required to go much further boggles the mind. Numerous clever non-collider experiments are searching for subtle deviations from predictions and could lead to a major discovery any day, but researchers are ultimately facing similar problems as their experiments grow more and more intricate. Particle physicists are approaching a technological and financial wall as they attempt to probe ever deeper layers of reality.

One of the most promising avenues for new discoveries is the detection of ripples in space-time known as gravitational waves. Researchers have now racked up dozens of chirps originating from cataclysmic crashes between black holes, and they are rapidly developing ways of picking up cosmic clangs indicative of even more dramatic events. Particle physicists are anxiously awaiting the 2030s, when they hope to see a trio of satellites known as the Laser Interferometer Space Antenna (LISA) go into operation. If it flies, LISA will be capable of picking up gravitational waves generated during the first fractions of a second after the Big Bang, an intense era in cosmic history at the frontier of the known laws of physics. In those early moments, some physicists expect, the universe existed in multiple phases at once — like a pot of boiling water. If so, the bubbling would have set off space-time ripples that LISA will be listening for.

“The Basic Laws of Human Stupidity,” Carlo M. Cipollo, UC Berkley, Economist, Historian

5 basic laws:

1. Always and inevitably, everyone underestimates the number of stupid individuals in circulation. (E.g., Nazi Germany)
2. The probability that a certain person is stupid is independent of any other characteristics of that person. (E.g., economics, education level, skillset)
3. A stupid person is a person who causes losses to another person or a group of persons while himself deriving no gain and even possibly incurring losses. (E.g., authoritarian governments who destroy their countries, financial meltdowns, etc.)
4. Non-stupid people always underestimate the damaging power of stupid individuals. In particular, non-stupid people constantly forget that at all times and places and under any circumstances, to deal with and (or) to associate with stupid people always turns out to be a costly mistake. (E.g., downplaying their impact, giving them the benefit of the doubt)
5. A stupid person is more dangerous than a pillager. (E.g., Bandits act typically in self-interest. Stupid people don’t consider collateral damage, even to themselves.)

Call it "Dunning-Kruger" on steroids. The lead description on Amazon is ominous:

An economist explains five laws that confirm our worst fears: stupid people can and do rule the world

Throughout history, a powerful force has hindered the growth of human welfare and happiness. It is more powerful than the Mafia or the military. It has global catastrophic effects and can be found anywhere from the world's most powerful boardrooms to your local bar.

It is human stupidity.

I apply stupidity not to intelligence but to behavior that, once achieving arguable success in an area of life, empowers said person to feel they have a right, and in their mind, a duty, to pontificate on other areas of life that they have no experience in, or clue.

 In 1862, a famous Irish physicist and mathematician, Lord Kelvin, estimated that Earth was between 20-million and 400-million years old. While that is an enormous span of time, even an age of 400 million years would make the planet quite young in relation to the rest of the universe. Lord Kelvin based his conclusion on a calculation of how long it would have taken Earth to cool if it had begun as a molten mass. While his estimate was wrong by a significant margin, his technique of drawing conclusions based on observations and calculations was an accurate scientific method. How Did Scientists Calculate the Age of Earth? NatGeo Education

Suffice it to say, Lord Kelvin, for whom the Kelvin scale in Thermodynamics is named for reflecting a "complete absence of thermal energy," was WAY out over his skis!

Lord Kelvin, God bless him, exhibited the logical fallacy called "appeal to authority." He appealed to the fact that he was a superstar in thermodynamics (KNIGHTED, for crying out loud), so he had to be right! The geologists, ahem, the people who study the structure and composition of the Earth, in his mindIn his mind, the geologists, ahem, the people who study the structure and composition of the Earth, were wrong.

So, the "bros" (and most of them are male), have the unfortunate habit of assuming after they conquered the hill in Silicon Valley and became "new money" millionaires and billionaires, they have a right and an obligation to pontificate on matters in society they have no experience in, or clue. The bros might spread misinformation online on a platform they bought that arguably fails to attract other customers and might sue those who have left. They might use their leverage to turn over precedents in our nation's highest court. They are Einstein in their areas of expertise, but Fredo in all others. They are over their skis. They read the Cliff Notes to Atlas Shrugged, and forgot that Ayn Rand ended up on the collectivist scheme she railed against in her latter years: Social Security. For the bros, the government is daddy bailing them out of a jam of their creation usually, and everyone else isn't "special" or daddy's favorite: they are. And they want what they want, damn the economy, the environment, and the planet—he who dies last with the gold wins.

The "bros" should study earnestly the real and fictional outcomes of Boesky and Gekko.

"B-boys and B-girls wield physics to pull off gravity-defying dance moves."

Okay, "gravity-defying" is a bit of hyperbole. Break dancing, as the article alludes, started in New York, and the movements can be found in martial arts like Brazilian Capoeira. It's more centrifugal force and torque, but I get that "gravity-defying" will get more clicks. I wish it didn't and the science behind it got more attention.

Two athletes square off for an intense dance battle. The DJ starts spinning tunes, and the athletes begin twisting, spinning and seemingly defying gravity, respectfully watching each other and taking turns showing off their skill.

The athletes converse through their movements, speaking through a dance that celebrates both athleticism and creativity. While the athletes probably aren’t consciously thinking about the physics behind their movements, these complex and mesmerizing dances demonstrate a variety of different scientific principles.

Breaking, also known as breakdancing, originated in the late 1970s in the New York City borough of the Bronx. Debuting as an Olympic sport in the 2024 Summer Olympics, breaking will showcase its dynamic moves on a global stage. This urban dance style combines hip-hop culture, acrobatic moves and expressive footwork.

In a study with potential implications for the oceans and human health, scientists reported elevated mercury levels in dolphins in the U.S. Southeast, with the greatest levels found in dolphins in Florida’s St. Joseph and Choctawhatchee Bays.

Dolphins are considered a “sentinel species” for oceans and human health because, like us, they are high up in the food chain, live long lives, and share certain physiological traits with humans. Some staples of their diet, such as spot, croaker, weakfish, and other small fish, are most vulnerable to mercury pollution and are also eaten by people.  

The study, which appeared in the journal Toxics, drew no conclusions about Florida and Georgia residents’ mercury levels or the potential health risks to humans. It did, however, cite previous research by a different group of researchers that found a correlation between high mercury levels in dolphins in Florida’s Indian River Lagoon and humans living in the area.

“As a sentinel species, the bottlenose dolphin data presented here can direct future studies to evaluate mercury exposure to human residents” in the Southeast and other potentially affected areas in the United States, the authors of the study in Toxics wrote.

The gravitational wave detectors LIGO and Virgo have detected a population of massive black holes whose origin is one of the biggest mysteries in modern astronomy. According to one hypothesis, these objects may have formed in the very early universe and may include dark matter, a mysterious substance filling the universe.

A team of scientists from the OGLE (Optical Gravitational Lensing Experiment) survey from the Astronomical Observatory of the University of Warsaw have announced the results of nearly 20-year-long observations indicating that such massive black holes may comprise at most a few percent of dark matter. Another explanation, therefore, is needed for gravitational wave sources. The results of the research were published in a study in Nature and a study in The Astrophysical Journal Supplement Series.

Various astronomical observations indicate that ordinary matter, which we can see or touch, comprises only 5% of the total mass and energy budget of the universe. In the Milky Way, for every 1 kg of ordinary matter in stars, there is 15 kg of dark matter, which does not emit any light and interacts only by means of its gravitational pull.

"The nature of dark matter remains a mystery. Most scientists think it is composed of unknown elementary particles," says Dr. Przemek Mr.óz from the Astronomical Observatory, University of Warsaw, the lead author of both articles. "Unfortunately, despite decades of efforts, no experiment (including experiments carried out with the Large Hadron Collider) has found new particles that could be responsible for dark matter."

Sixty years ago today, I was a month and twelve days from my second birthday. Sixty years ago today, my world was changed by President Lyndon Baines Johnson signing the Civil Rights Act, ninety-nine years after the surrender at Appomattox, Virginia, and the cessation of the insurrection known by the Orwellian name: "Civil War."

A year prior, my parents would see four little black girls murdered by Klansmen on her 38th birthday (September 15, 1963), only exacerbated by the assassination of President John F. Kennedy (November 22, 1963), which propelled his then Vice President into the presidency. The year prior to that, barely on the planet, the "Missiles of October" threatened my brief existence as nuclear weapons had been staged off the coast of Florida by Russia in Cuba (October 14, 1962). The sixties may have given us the utopian vision of Star Trek, but it was not the "Dawning of the Age of Aquarius" as the Fifth Dimension sang joyfully.

The project to dismantle American democracy started today as well.

The 9-0 vote on Brown vs. Board of Education was untenable at the time for Southern Dixiecrats, who wanted it as a ballot initiative because they knew they had the votes to defeat it, and "put things back in proper order," the hierarchy of the chattel enslavement of kidnapped humans, and Jim Crow. The parties "flipflopped" as Dixiecrats left the Democratic Party, after the Voting Rights Act of 1965 the next year, and the Fair Housing Act of 1968, migrating to the Republican Party, all willing to absorb southern racists with the slick, Hollywood line a B-Movie Actor gave them as mantra: "I didn't leave the Democratic Party; the Democratic Party left me." After the Powell Memo that set the framework for the first decades-long lurch to fascism, "The Gipper" was born, the first of three avatar presidents that made you feel nostalgic for halcyon days that have never existed, all of them always preceded by memos, the Project for a New American Century, and the frightening, dystopian document Project 2025.

It was always going to come to this.

My letter to the President after the "Supreme Court" decision establishing a monarch:

The Revolutionary War was fought to get out of the authoritarian rule of a tyrant, King George of England. This "Supreme Court" is neither. It is broken, and I will be voting for you, working to elect Josh Stein in North Carolina, and donating to both campaigns. I feel passionate about the successes of this administration, and we're so close to addressing climate change. Mr. President, please consider something that goes against the grain and your respect for institutions: stack the court. Propose that if re-elected, you will rebalance the high court, which is clearly activist, out-of-touch, and out of control. This convicted felon, this adjudicated rapist CANNOT regain political power, or else we will be a byword, a proverb, an oxymoron. If the U.S. falls, so will every democracy across the globe, which is the goal of Vladimir Putin and the Russian government, a kleptocracy masquerading as a state. The extinction-level event for the dinosaurs was a meteor off the Gulf of Mexico. I don't see the human species continuing if this cretin gets back into the Oval Office. The United States is an essential nation. Thank you.

My biggest critique of the Democratic Party is they lack strategic vision. The evisceration of Roe vs. Wade was a decades-long strategy that the DNC treated as a political football. The party had since 1973 7 Republican - 2 Democratic justices' decision to codify women's bodily autonomy into law, but it was too useful a political football, so no one tried. Meanwhile, the Republicans are following no rules other than the grasp and maintenance of power; call it class warfare or white supremacy; it doesn't matter.

The Dred Scott Decision by Chief Justice Robert B. Taney is credited for the impetus of the "Civil War," resulting in about 622,000 countrymen dead from both sides, only surpassed by the ineptitude of the tyrant who botched the Coronavirus response, who Chief Justice John Roberts just gave dictatorial powers to if he were to return to office January 20, 2025.

For the maintenance of a toxic social hierarchy, may history list John Roberts as our last Chief Justice, the one who destroyed our republic and democracy worldwide.

The sixth mass extinction event clearly will not need meteors, just incompetent, pious jurists who think themselves gods.

Excerpt from Facts, Fascism, and Fascists, Friday, January 24, 2020

Tens of millions of Americans, lumped into a diffuse and fractious movement known as the Christian right, have begun to dismantle the intellectual and scientific rigor of the Enlightenment. They are creating a theocratic state based on “biblical law,” and shutting out all those they define as the enemy. This movement, veering closer and closer to traditional fascism, seeks to force a recalcitrant world to submit before an imperial America. It champions the eradication of social deviants, beginning with homosexuals, and moving on to immigrants, secular humanists, feminists, Jews, Muslims and those they dismiss as “nominal Christians” — meaning Christians who do not embrace their perverted and heretical interpretation of the Bible. Those who defy the mass movement are condemned as posing a threat to the health and hygiene of the country and the family. All will be purged.

The followers of deviant faiths, from Judaism to Islam, must be converted or repressed. The deviant media, the deviant public schools, the deviant entertainment industry, the deviant secular humanist government and judiciary and the deviant churches will be reformed or closed. There will be a relentless promotion of Christian “values,” already under way on Christian radio and television and in Christian schools, as information and facts are replaced with overt forms of indoctrination. The march toward this terrifying dystopia has begun. It is taking place on the streets of Arizona, on cable news channels, at tea party rallies, in the Texas public schools, among militia members and within a Republican Party that is being hijacked by this lunatic fringe.

The Christian Fascists Are Growing Stronger, Chris Hedges, Truth Dig

There has been high praise for the House Impeachment Managers: Representatives Jerrold Nadler, Val Demings, Zoe Lofgren, Sylvia Garcia, Jason Crow, Hakeem Jeffries; especially its leader, Adam Schiff. My fraternity brother, House Manager Hakeem Jeffries probably accomplished the first hip hop Biggie Smalls' mic drop rebuttal in impeachment history. I'm sure it completely went over Jay Sekulow's head.

Sadly, facts don't matter to fascists.

Belief in pseudoscience extended across the Nazi high command, from the Führer's search for 'death rays' to Goebbels reading Nostradamus in bed.

This is a dense and scholarly book about one of the pulpiest subjects of the past 70 years - the relationship between the Nazi party and the occult, which has been much debated across popular culture both in fiction (Captain America: Civil War, Hellboy, Wolfenstein, the Indiana Jones series, Iron Sky, The Keep and countless others) and in innumerable schlocky works of pseudoscience with runes and swastikas on the covers.

As it turns out, though, even this sober, academic treatment of the topic reveals stranger-than-fiction truths on every page.

Here are a few of them. In the 1930s, Hitler made extensive notes on a book called Magic: Theory, History, Practice and underlined passages such as "He who does not carry demonic seeds within him will never give birth to a new world". In 1934, the year after he was appointed chancellor of Germany, he hired a dowser to go over the Reich Chancellery in search of "death rays" that might damage staff in the building. He and Himmler held frequent conversations about "the World Empire of Atlantis, which fell victim to the catastrophe of the moons falling to Earth" and about a discredited pseudoscience called Welteislehre, or World Ice Theory, which taught that the cosmos was made of ice and which they saw as a "Germanic" counterbalance to the "Jewish" theory of relativity.

*****

The spectacle of televised debates ignores one key fact: the television was invented September 27, 1927 by Philo Taylor Farnsworth. Fast forward 33 years to the first televised debate between Kennedy and Nixon. I’ve heard that people listening to the debate by radio thought Nixon was victorious, because he had knowledge that Kennedy did not have. However, Kennedy “looked good,” he was young, tan, and Nixon was nursing an infection. It was the first instance of style over substance. Had Nixon won, there might not have been a Civil Rights Act, a Voting Rights Act, a Fair Housing Act, a Vietnam conflict, or Watergate.

In recent memory, John Kerry bested George W. Bush in every debate, as well as did Al Gore prior to him, and Hillary mopped the floor with orange bone spurs. The election at this time, is “baked in.” It will depend on which side gets its base out. Corporate debates are superfluous to democracy, and useless theater. If we copy anything from Great Britain, we should have a shorter campaign period.

If Biden wins (and historian Allan Lichtman thinks he will - he’s predicted 9 of 10 of the last presidential elections accurately), we have to think about who will represent the party and win in 2028. His "thirteen keys model" goes in the garbage if Biden is forced off the ticket. The twice-impeached, instigator of the insurrection, 88-count indicted, 34-count convicted (sentencing September 18th), adjudicated fraudster and rapist has not been asked to leave the ticket in all seriousness, nor is his personality cult likely to do so. This ageism-on-steroids was started by publications like the New York Times, and unlike the propaganda we've been sold about news outlets, they are more concerned with the bottom-line than holding power accountable, and they are loathe to print retractions admitting mistakes.

We will have a few seconds to breathe after this election cycle, if we're successful, to start thinking about 2028: whichever party controls the White House will be in charge of the 2030 Census, meaning the drawing of congressional districts. The party in power gets to draw congressional districts, i.e., the incumbents get to PICK their voters, which doesn't sound like how democracy is supposed to work! Fairness would be an AI algorithm that draws congressional maps with no respect to party, making the lawmakers actually speak to their constituents and have to WORK for every vote. I am fighting for democracy because, we haven't achieved it yet. The Founding Fathers are lionized, mythologized, and apotheosized as wise men, and they were. William Hogeland, historian, writes "The Hamilton Scheme: An Epic Tale of Money and Power in the American Founding," that though Lin Manuel Miranda had us jamming to the hip hop play with its diverse cast, Hamilton was antidemocracy, except for the ruling class in America that he was engineering, who, like their descendants, had an aversion to paying taxes.

Thrilling to the romance of becoming the one-man inventor of a modern nation, our first Treasury secretary fostered growth by engineering an ingenious dynamo—banking, public debt, manufacturing—for concentrating national wealth in the hands of a government-connected elite. Seeking American prosperity, he built American oligarchy. Hence his animus and mutual sense of betrayal with Jefferson and Madison—and his career-long fight to suppress a rowdy egalitarian movement little remembered today: the eighteenth-century white working class.

If you're wondering why lawmakers seem older than you would like, or why after an election that showed a plurality of voters voting for another outcome, gerrymandering is the answer. Case-in-point: North Carolina GOP lost the popular vote in 2018, but gained seats in the house, to now a veto-proof majority. That is gerrymandering, that is the Census. My biggest criticism of the Democratic Party is they are great tacticians, and poor strategists. I hope they're gaming this out, because both National Committees (D&R) did the citizenry a disservice by running primary dog-and-pony shows in 2016, 2020, and 2024, each with diverse voices, diverse opinions, and DIVERSITY, only to end up with two old white guys in the mold of George Washington, so that Barack Obama can be seen as a one-off fluke. Heaven help us if a woman or another person of color can run the country as effectively as the 43 other white males that preceded the first black president, and it seems the oligarchy is determined that that will be the last deviation from their preferred "norm."

THESE are the times that try men's souls. The summer soldier and the sunshine patriot will, in this crisis, shrink from the service of their country; but he that stands by it now, deserves the love and thanks of man and woman. Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value. Heaven knows how to put a proper price upon its goods; and it would be strange indeed if so celestial an article as FREEDOM should not be highly rated. Britain, with an army to enforce her tyranny, has declared that she has a right (not only to TAX) but "to BIND us in ALL CASES WHATSOEVER" and if being bound in that manner, is not slavery, then is there not such a thing as slavery upon earth. Even the expression is impious; for so unlimited a power can belong only to God.

I'm tired too. But psychopaths don't take holidays, and not only democracy, but the planet will be impacted by the next election, and who wields now, god-like powers. My prediction is that the Insurrection Act will be invoked by the next president, either to quell another cosplay/Civil War/January 6 redux, or to imprison citizens, "disappear them" by deportation, or into American Gulags like Gitmo and black sites we thankfully have never heard of.

We are in a modern American Crisis, and the future will be shaped by what we do, win, or lose, in the next few months. We are not voting for a candidate, we are voting for Democracy, "Life, Liberty, and the Pursuit of Happiness." Those words should matter.

“On **May 17, 1954**, U.S. Supreme Court Justice Earl Warren delivered the unanimous ruling in the landmark civil rights case Brown v. Board of Education of Topeka, Kansas. State-sanctioned segregation of public schools was a violation of the 14th Amendment and was, therefore, unconstitutional. This historic decision marked the end of the "separate but equal" precedent set by the Supreme Court nearly 60 years earlier in Plessy v. Ferguson. It served as a catalyst for the expanding civil rights movement during the decade of the 1950s.”

Dr. Martin Luther King Jr was assassinated on April 4, 1968, a Thursday. My graduating kindergarten class at Bethlehem Community Center in Winston-Salem, North Carolina, was told by our teachers on Friday, who cried with us and reassured us that the men outside with Confederate flags, shooting in the air, reveling “that n----r’s dead” would not harm us, or prevent our celebration. We slept as well [as possible] through nap time and dressed for our day and [our] parents. Not one child in my photo of the event is smiling. Not one.

I attended segregated schools in Winston-Salem, NC, until my fourth grade year in 1971. “All deliberate speed” had some considerable foot-dragging.

I was bused across town for 4^th grade only to Rural Hall, and their kids were bused across town to Fairview Elementary for 5th and 6th grade. I was bused to Mineral Springs Middle School for 7th -8th grade. ALL the former Black High Schools, like Atkins, Carver, Hanes, and Paisley, had to be “9th and 10th grades only,” as North, East, Parkland, and West were reserved for the higher grades for high school graduation.

“We have fought hard and long for integration, as I believe we should have, and I believe that we will win, but I have come to believe that we are integrating into a burning house. I’m afraid that America has lost the moral vision she may have had,” as the nation is not deeply concerned “with the plight of the poor and disenfranchised.” This failure, King argued, would only further stoke “the anger and violence that tears the soul of this nation. I fear I am integrating my people into a burning house.” Dr. King confessed to his friend, the Civil Rights activist and entertainer Harry Belafonte.

I am sixty-one years old, a grandfather, and a late entrant to the ranks of a Ph.D. I am sad to say that despite the movement's optimism, NOTHING has changed.

Worrying trend Reliable climate models are needed so that societies can adapt to the impact of climate change. (Courtesy: Shutterstock/Migel)

It was a scorcher last year. Land and sea temperatures were up to 0.2 °C (32.36 °F) higher every single month in the second half of 2023, with these warm anomalies continuing into 2024. We know the world is warming, but the sudden heat spike had not been predicted. As NASA climate scientist Gavin Schmidt wrote in Nature recently: “It’s humbling and a bit worrying to admit that no year has confounded climate scientists’ predictive capabilities more than 2023 has.”

As Schmidt went on to explain, a spell of record-breaking warmth had been deemed “unlikely” despite 2023 being an El Niño year, where the relatively cool waters in the central and eastern equatorial Pacific Ocean are replaced with warmer waters. Trouble is, the complex interactions between atmospheric deep convection and equatorial modes of ocean variability, which lie behind El Niño, are poorly resolved in conventional climate models.

Our inability to simulate El Niño properly with current climate models (J. Climate 10.1175/JCLI-D-21-0648.1) is symptomatic of a much bigger problem. In 2011 I argued that contemporary climate models were not good enough to simulate the changing nature of weather extremes such as droughts, heat waves and floods (see “A CERN for climate change” March 2011 p13). With grid-point spacings typically around 100 km, these models provide a blurred, distorted vision of the future climate. For variables like rainfall, the systematic errors associated with such low spatial resolution are larger than the climate-change signals that the models attempt to predict.

Reliable climate models are vitally required so that societies can adapt to climate change, assess the urgency of reaching net-zero or implement geoengineering solutions if things get really bad. Yet how is it possible to adapt if we don’t know whether droughts, heat waves, storms or floods cause the greater threat? How do we assess the urgency of net-zero if models cannot simulate “tipping” points? How is it possible to agree on potential geoengineering solutions if it is not possible to reliably assess whether spraying aerosols in the stratosphere will weaken the monsoons or reduce the moisture supply to the tropical rainforests? Climate modelers have to take the issue of model inadequacy much more seriously if they wish to provide society with reliable actionable information about climate change.

I concluded in 2011 that we needed to develop global climate models with spatial resolution of around 1 km (with compatible temporal resolution) and the only way to achieve this is to pool human and computer resources to create one or more internationally federated institutes. In other words, we need a “CERN for climate change” – an effort inspired by the particle-physics facility near Geneva, which has become an emblem for international collaboration and progress.

Two researchers have revised the Drake equation, a mathematical formula for the probability of finding life or advanced civilizations in the universe.

Abstract
This study examines the hypothesis that the rapid development of Artificial Intelligence (AI), culminating in the emergence of Artificial Superintelligence (ASI), could act as a "Great Filter" that is responsible for the scarcity of advanced technological civilizations in the universe. It is proposed that such a filter emerges before these civilizations can develop a stable, multiplanetary existence, suggesting the typical longevity (L) of a technical civilization is less than 200 years. Such estimates for L, when applied to optimistic versions of the Drake equation, are consistent with the null results obtained by recent SETI surveys, and other efforts to detect various techno-signatures across the electromagnetic spectrum. Through the lens of SETI, we reflect on humanity's current technological trajectory – the modest projections for L suggested here, underscore the critical need to quickly establish regulatory frameworks for AI development on Earth and the advancement of a multiplanetary society to mitigate against such existential threats. The persistence of intelligent and conscious life in the universe could hinge on the timely and effective implementation of such international regulatory measures and technological endeavors.

The most surprising revelation from NASA's Curiosity Mars Rover—that methane is seeping from the surface of Gale Crater—has scientists scratching their heads.

Living creatures produce most of the methane on Earth. But scientists haven't found convincing signs of current or ancient life on Mars, and thus didn't expect to find methane there. Yet, the portable chemistry lab aboard Curiosity, known as SAM, or Sample Analysis at Mars, has continually sniffed out traces of the gas near the surface of Gale Crater, the only place on the surface of Mars where methane has been detected thus far. Its likely source, scientists assume, are geological mechanisms that involve water and rocks deep underground.

If that were the whole story, things would be easy. However, SAM has found that methane behaves in unexpected ways in Gale Crater. It appears at night and disappears during the day. It fluctuates seasonally and sometimes spikes to levels 40 times higher than usual. Surprisingly, the methane also isn't accumulating in the atmosphere: ESA's (the European Space Agency) ExoMars Trace Gas Orbiter, sent to Mars specifically to study the gas in the atmosphere, has detected no methane.
