Researchers from the University of Tsukuba have obtained atomic-level insights into the structure of the phosphoketolase enzyme, which will help researchers optimize this enzyme for chemical feedstock synthesis

Tsukuba, JapanPharmaceuticals, plastics, and other industries use enzymes to help synthesize molecular feedstocks. Enzymes taken straight from microbes such as bacteria are often not optimal for industrial use; one issue is that they often do not survive the elevated temperatures that speed up a synthesis. Genetic engineering can help tailor enzymes for these purposes. Knowledge of the exact atom-by-atom structure of the original enzyme is important in understanding enzyme function in nature, thus providing insight as to how to optimize the genetic engineering of enzymes. However, X-ray crystallography, a common technique for determining an enzyme's structure as a critical step in this process, can unfortunately alter its structure as well.

A technique known as cryogenic electron microscopy (cryo-EM) can provide a similar level of structural detail to that of X-ray crystallography whilst retaining the native enzyme's structure. In fact, the 2017 Nobel Prize in Chemistry was awarded for using this technique to determine the structure of biological molecules. Now, in a study recently published in theJournal of Structural Biology, researchers from the University of Tsukuba and collaborating partners have used cryo-EM to determine the structure of the fermentation enzyme phosphoketolase. This work will facilitate genetic engineering of the enzyme for industrial syntheses.

"X-ray crystallography has revolutionized how researchers identify protein structures, but the development of alternative means that better reflect the structures seen in biology are invaluable," explains senior author Professor Kenji Iwasaki. "Our use of cryo-EM as an imaging tool has uncovered previously obscured structural detail in phosphoketolase that will directly benefit the chemical industry."

The researchers report two main findings. First, eight phosphoketolase units cluster together into one structure, known as an octamer. Second, they observed details of a chain of amino acids known as the QN-loop that may dictate whether the functional site of the enzyme is open or closed. This is a possible means of enhancing the chemical output of the enzyme.

X-ray crystallography obscures the structural detail provided by cryo-EM. The octamer was previously observed by X-ray crystallography but was thought to simply be a measurement artifact. Additionally, X-ray crystallography misses the open/closed structural details.

"Industry will now be able to correlate the function of phosphoketolase with its correct structure," says Iwasaki. "We expect that these insights will remind researchers that X-ray crystallography isn't necessarily the final word on enzyme structure; cryo-EM can offer valuable insights."

The results of this study are important for optimizing the performance of a fermentation enzyme that is useful for performing chemical syntheses in industry. By using enzyme structural insights to maximize the success of genetic engineering, feedstocks can be produced for pharmaceuticals, plastics, and other materials in an environmentally sustainable manner.

Ancient Protein Rubisco Could Be Used to Save Future Food Crops From Dying in Hot Climates – The Daily Beast

Posted: April 19, 2022 at 2:40 am

When it comes to food, humanitys looking down the barrel of a gun. The worlds population will balloon to almost 9.8 billion by 2050, leading to an expected 60-percent increase in demand for food. And the devastating effects of climate change arent doing any favors for our farming.

But there may be a silver liningand it involves backpedaling evolution.

Researchers at Cornell University have found a way to resurrect an ancient form of an enzyme called rubisco, or RuBisCo, that promoted photosynthesis in plants millions of years ago, when Earth was experiencing one of its hottest climates in the last 50 million years. In a study published April 15 in the journal Science Advances, the researchers were able to use modern-day versions of rubisco to piece together an idea of what the enzyme looked like in ancient times. As a result, scientists may be able to harness its power once again to help ensure our crops of the future can adapt and resist climate change and provide us with all the fresh fruits, vegetables, and grains we need.

Although plants suck in carbon dioxide and produce oxygen, they arent exactly able to just make use of carbon dioxide in its current, gaseous form. Rubisco, short for ribulose-1,5-bisphosphate carboxylase/oxygenase and the most abundant enzyme found on Earth, transforms carbon dioxide into a biologically friendly form, which plants use to build their tissues.

One problem with rubisco is that it also interacts with oxygen. This undesirable mingling produces toxic byproducts that slow down photosynthesis and, by extension, impact crop yield. Scientists have been sussing out ways to mitigate this issue and improve crop production by genetically engineering plants to make an algae-derived form of the enzyme or other tweaks. But these efforts havent really borne fruit yet.

To solve this conundrum, the Cornell researchers took a trip down memory lane25 to 50 million years ago when Earth was much hotter thanks to high amounts of atmospheric carbon dioxide (a whopping 500 to 800 parts per million, compared to the 413 ppm estimated in 2020). This meant modern-day rubisco likely had an ancestral version that was adapted to working under such extreme carbon dioxide levels.

The Cornell team recreated a phylogeny, a tree-like diagram that traces the evolutionary relationships between its members and shows how they evolved from a common ancestor. They did this by analyzing rubisco genes in plants of the Solanaceae (nightshade) family, which include potato, pepper, tomato, eggplant, and tobacco. And from this family tree, the researchers were able to create and gauge the biological activity of nearly a hundred of these potential ancient rubiscos in the lab using the bacteria E. coli.

By getting a lot of [genetic] sequences of rubisco in existing plants, a phylogenetic tree could be constructed to figure out which rubiscos likely existed 20 to 30 million years ago, Maureen Hanson, a molecular biologist at Cornell and the new studys senior author, said in a press release. We were able to identify predicted ancestral enzymes that do have superior qualities compared to current-day enzymes.

The next big step for the research team will be to transfer the reconstructed versions of the rubisco genes into plants from the Solanaceae family like tomatoes and potentially others like rice or soybean and see whether photosynthesis activity improves and props up crop yield.

For the next step, we want to replace the genes for the existing rubisco enzyme in tobacco with these ancestral sequences using CRISPR [gene-editing] technology, and then measure how it affects the production of biomass, Hanson said. We certainly hope that our experiments will show that by adapting rubisco to present-day conditions, we will have plants that will give greater yields.

To a stressed planet with many hungry mouths to feed, that sounds like a good start.

Wrap: four organisms that could be brought back from the brink of extinction (and beyond) – Cosmos

Posted: April 19, 2022 at 2:40 am

We went on a hunt for the coolest (and spookiest) stories about bringing vulnerable animals back from the brink of extinction or, in some cases, bringing them back from the dead.

De-extincting the Tassie tiger: an Australian Jurassic Park?

In a stunning announcement in March, the University of Melbourne announced it had received $5 million in funding for a new research lab, the Thylacine Integrated Genomics Research Lab (TIGRR), which will primarily look to bring back the extinct thylacine (Tasmanian tiger) using genetic engineering and cloning techniques.

Once abundant in Tasmania, the tigers were hunted to extinction by European settlers who thought they were killing their livestock.

The ambitious new project will take a thylacine genome, salvaged from a preserved specimen, and use it as a map to re-engineer the genome inside a living cell from the creatures closest living relative, the Dunnart. Then, it will in theory clone a living thylacine from that living cell.

But, to paraphrase Jeff Goldblum, is this a case of spending so much time wondering whether they could, they never stopped to think whether they should?

Lost South American wildflower named extinctus rediscovered (but still endangered)

In a rare but beautiful case of redemption, the orange tropical wildflowerGasteranthus extinctus,endemic to the Andean foothills in Ecuador, was thought to have gone extinct 40 years ago.

But in a stroke of luck, a team of researchers who set out in hopes of rediscovering the plant managed to find a specimen growing, proving that its still clinging on (though still perilously endangered).

We walked into Centinela thinking it was going to break our heart, and instead we ended up falling in love, said one of the lead researchers.

Bringing back the iconic woolly mammoth

Back in 2017, scientists from Harvard University stunned the world when they announced plans to bring back the iconic woolly mammoth.

These iconic, massive elephant-like creatures had shaggy fur that helped them brave the frosty wilds of the last Ice Age.

De-extincting the mammoths, the scientists said, would be possible because mammoth DNA remains in frozen carcasses found buried in the permafrost in places like Siberia. They say theyre going to use elephant DNA to help patch up the holes, and create a living mammoth cell, which they will implant into an elephant to carry to term, giving birth to a real life woolly mammoth.

But, why do it?According to Revive and Restore, a genomic research and restoration project, the absence of the woolly mammoths from the tundra stopped the compaction of snow, meaning extreme winter cold didnt penetrate the soil, leading to the accelerated melting of the permafrost.

So, the theory goes, these new mammoths will help reverse the melting of these ice stores that are full of greenhouse gases.

Bringing back the Christmas Island rat

It might be a slightly less iconic species, but the Christmas Island rat was yet another fatality of European expansion, vanishing from the island 119 years ago because of diseases brought from the strange, foreign land.

This rat still has many living relative species, making it potentially a model species for this kind of de-extinction.

GMO debate is not over

In his op-ed Saving the planet one bite at a time, (April 7), Prof. Sylvain Charlebois says the new United Nations Intergovernmental Panel on Climate Change (IPCC) report is worth the read but it seems he did not actually read it himself. Charlebois says, The report sees global trade and genetic engineering as part of the solution, but the report doesnt even mention genetic engineering (genetically modified organisms or GMOs). Yet he then states, it is time to put the anti-GMO rhetoric to rest. Whatever reason he has for making this passionate statement, the IPCC is not it, and readers deserve correct information. Falsely reporting on the IPCC content trivializes the serious challenge before us. Furthermore, this attempt to shut down debate over GMOs comes at a time when we need more debate, not less: as the Canadian Food Inspection Agency and Health Canada are proposing to remove environmental and food safety assessments for some genetically engineered seeds and foods.

Brott deserves a statue

The sudden recent death of Boris Brott in such a tragic manner is truly heartbreaking. That it should happen on a street in Hamilton, the city he loved so well, is especially painful.

Boris Brott was a world renowned maestro, and a strong proponent of this city. The enthusiasm and obvious joy he brought to his performances was always uplifting to witness.

I was lucky to see him perform here in Hamilton and more recently at the National Arts Centre in Ottawa. His enthusiasm, energy and sense of fun was always evident.

I think a fitting and appropriate tribute to Boris Brott would be to have his likeness in a statue erected in Gore Park, honouring his decades long musical contributions to Hamilton. Honouring him this way would also promote his legacy of a love for music.

Perhaps it might replace the contentious statues of John A. Macdonald or Queen Victoria. The loss of a person of Brotts stature deserves a monument at the centre of this city.

Standardize traffic lights

Who knows when a green light with a red flashing hand signal is going to yellow and one second later to red? Or countdown lights some turn red at 0; other countdowns go from 0 to a red hand signal for you to guess at how long you have to go through the intersection safely. A quick glance into your review mirror tells you that the car behind you is on your bumper; to make a quick decision to stop could end up in a collision. Split second decision. I hate it! You slow down nearing an intersection not knowing weather you can safely make it through the light only having to speed up as the light hasnt yet changed and the guy behind you is honking his horn pushing you through. Then you worry if this was a red-light camera intersection. I ask myself every day, why cant Hamilton synchronize all the traffic lights for continuity, so that every driver knows when to slow down to stop?

Saving mine for buck-a-beer

The letter writers complaining about getting a refund on the licence stickers are getting tiring. Really? I never got a red cent back from their beloved Liberals, in fact I was gouged enough on everything from electricity to public services to make up for a centurys worth of overpayment to their provincial coffers.

I, for one, appreciate that I dont have to spend money on stickers for my vehicles and was grateful to get my refund. You want to donate your refund to Del Duca or any other cause, knock yourself out. Im saving mine for buck-a-beer.

In praise of journalists

If not for journalists, we would not have found out that the abundance of rapid tests in Ontario were given to private schools. In fact they were given more tests than LTC homes and paramedics put together. I am a proud supporter of my local newspaper and thankful for the truth seekers out there. Keep up the good work the general public needs to know the truth

Depraved Russian soldiers

For the children, written in Russian, on the side of an exploded missile, in the midst of dozens of Ukrainian dead. Unarmed civilian, women, children and aged. Can we imagine much that is more barbaric, uncivilized and depraved? We wonder if this dedication was the sick humour of the commanding officer, or was a suggestion from petulant Putin personally. It certainly leaves no doubt as to their evil intentions. I shall never visit Russia.

Revising the lifecycle of an important human parasite | Penn Today – Penn Today

Posted: April 19, 2022 at 2:40 am

We have been interested in the romantic life of the parasite Cryptosporidium for some time, says Boris Striepen, a scientist in Penns School of Veterinary Medicine.

Cryptosporidium is a leading cause of diarrheal disease in young children around the world. The intestinal parasite contributes to childhood mortality and causes malnutrition and stunting. How a parasite like this one reproduces and completes its life cycle has significant impact on child health.

Its the product of parasite sex, that is infectious agent here, a spore, that is transmitted by contaminated water, Striepen says. So, if you break its ability to have sex, you would break the cycle of transmission and infection.

In a new paper in PLOS Biology, Striepen and colleagues in his lab tread new ground in understanding how Cryptosporidium reproduces inside a host. Using an advanced imaging technique allowed the scientists to observe the entire lifecycle in the laboratory. They found the parasite completes three cycles of asexual replication and then directly switches to male and female sexual forms. Their observations refute an intermediate stage that was introduced in the 1970s and align well with the original description of physician and parasitologist Edward Tyzzer who discovered this pathogen more than a century ago.

What we have shown contradicts what you see in most textbooks today, including the description at the Centers for Disease Control and Prevention website, Striepen says. Its really a super simple lifecycle that is completed in a single host in three days and only has three characters: asexual cells, male cells, and female cells.

Other parasites, such as the malaria parasite Plasmodium, a cousin of Cryptosporidium, have more complicated and lengthy paths to follow an overall similar life cycle. While Crypto completes its lifecycle in one host, most malaria parasites move between two: a mosquito, where the parasites sexual reproduction occurs, and a human, where its asexual replication occurs.

Cryptosporidium is a great model to study parasite development; you can see analogous steps to what happens with the malarial parasite, but its much simpler because it all happens over only three days in one host, and we can observe it in simple cell cultures, Striepen says.

In earlier work on Cryptosporidium, Striepen and colleagues had found that sexual reproduction appeared necessary for the parasite to move from one host to infect another but also to sustain itself in a host during chronic infection. Blocking developmental progression and parasite sex thus presents itself as a strategy to cure or prevent infection.

Cryptosporidium is a minuscule single-cell parasite that invades and reproduces within the cells of the intestine of its hosts. To get a closer look at what was happening, the researchers developed a live-cell microscopic imaging technique to track the progression of the parasite through multiple days in cell cultures. Using genetic engineering they added a fluorescent label to the nucleus of each parasite, allowing them to observe the replication of the parasite in real time and to distinguish its different lifecycle stages.

What they saw was the parasites count to three, says Striepen. Rather than responding to environmental cues, the parasites followed a rigid built-in plan. After infecting a culture, the parasite underwent three cycles of asexual reproduction. Each cycle took about 12 hours, during which the parasite established a home within the host cell and replicated itself resulting in eight new infectious parasites. Those were then released to infect surrounding host cells.

After these three waves of amplification, their fate changes abruptly, and they turn into either male or female gametes, or sex cells, in a process that also took about 12 hours. Tracking individual parasites and their offspring the researchers found no evidence for a specialized intermediate form assumed by many textbooks, demonstrating direct development.

Interestingly, the parasite appeared pre-committed to their future fate and carried that plan from one host cell into the next in a way not yet understood.

The researchers were intrigued to see that male and females arise from the infectious forms released from the same asexual parasites. One of the really interesting aspects of sexual identity here is that it is not inherited and hard-wired in the genome but much more fluid, Striepen says. Theres an asexual cell that divides itself into genetically identical clones, and then those clones somehow become male or female on the fly, resulting in dramatically different cell shape and behavior.

Future research will focus on the molecular mechanism of commitment to understand how this life cycle is programmed into the parasites biology. Understanding the life cycle of Cryptosporidium is critical in thinking about how to create a vaccine or therapy for the disease, Striepen says.

How cells make decisions and execute developmental plans is one of the most fundamental questions in biology. Cryptosporidium offers a tractable system to better understand this mechanism in parasites. Hopefully we can gain insights that contribute to the understanding of cryptosporidiosis and malaria and lead the way to new urgently needed interventions for these important diseases.

Boris Striepen is the Mark Whittier and Lila Griswold Allam Professor of Microbiology and Immunology at the University of Pennsylvania School of Veterinary Medicine.

Striepens coauthors were lab members Elizabeth D. English, Amandine Gurin, and Jayesh Tandel.

The study was supported by grants from the National Institutes of Health to Striepen and a postdoctoral fellowship from the European Molecular Biology Organisation to Gurin.

What you need to know about natural, organic and vegan wines – Atlantic City Weekly

Posted: April 19, 2022 at 2:40 am

If you are seeking a naturally lower calorie wine, look for dry wines with a lower ABV, such as Prosecco (brut or extra dry), dry Riesling, or Gamay. These wines typically fall on a spectrum of 80 to 120 calories per glass.

Q: Karen S. from Margate asks, Whats the difference between a natural wine and an organic wine?

A: Hi Karen! Natural wines and organic wines have a lot in common. Most significantly they share a concern for the earth and sustainable practices, but there are also several key differences.

To be certified organic by the USDA, a wine must be made without genetic engineering, and it must undergo a rigorous process of inspections and assessments. The grapes must be grown organically without synthetic fertilizers, and all other ingredients such as yeast and fining agents must be certified organic, as well. While sulfites are commonly added to wines as an additional preserving agent or to enhance flavor, organic wines cannot have added sulfites. Wines labeled as made with organic grapes have slightly less restrictions, but it is still a feat for winemakers to achieve this certification.

Natural wine, on the other hand, is not a legal certification. Rather, its a loose term that refers to wines made with little to no intervention by the winemaker. This means grapes are grown without the assistance of pesticides, grapes are handpicked, and juice is fermented into wine using only native yeasts. These yeasts occur naturally on the fruit, and winemakers allow fermentation to start spontaneously, rather than controlling fermentation with the addition of cultured yeasts. While natural wines wont necessary be certified organic, one could argue that they exemplify the most ancient, non-invasive method of winemaking.

Synthetic Biology Market Present Scenario on Growth Analysis Along with Key Industry Players – Taiwan News

Posted: April 19, 2022 at 2:40 am

Synthetic biology is a novel area of research that is the amalgamation of multiple disciplines such as molecular biology, biotechnology, biophysics and genetic engineering among others. There are chiefly two approaches used in synthetic biology namely, top down approach and bottom up approach. Top-down approach involves the re-design and fabrication of existing biological systems for producing synthetic products. Bottom-up approach involves designing and construction of de novo biological systems or devices that do not exist in nature. An impending need to understand the functioning of genetic elements, cells and biological processes has led to the emergence of synthetic biology. Synthetic biology products are used across many industries, including pharmaceutical & diagnostics, energy, bioplastics and environment.

World synthetic biology market was valued at $ 5,245.7 million in 2015, growing at a CAGR of 23% during the forecast period. Assistance from government and private organizations, rising number of synthetic biology research entities and declining cost of DNA sequencing & synthesizing are the major factors driving the market growth.

12 Reader Views on Where America Is Going Wrong – The Atlantic

Posted: April 19, 2022 at 2:40 am

This is an edition of Up for Debate, a newsletter by Conor Friedersdorf. On Wednesdays, he rounds up timely conversations and solicits reader responses to one thought-provoking question. Soon after, he publishes some thoughtful replies. Sign up for the newsletter here.

Last week I asked readers, What worries you most about the direction of the country? For Adam, the answer is rooted in a perception that were underestimating what is at stake when we act:

The thing I worry about the most is breaking unfixable things. I think the modern era, especially defined by the GOP (but also by the far left), is more about performance than production. Our leaders dont seem to care about fixing problems, or even proposing solutions, just popularity contests, scoring points, and seeing how far they can push the envelope to stay in power. This didnt used to worry me as much. While Congress was always a procrastinator, they tended to get their homework done on time.

But I fear in the next few years, something will break that cant be fixed. Republicans are telling us theyre going to try to steal the next election. Democrats seem to be jamming their heads in the sand to avoid the issue and hope that two centuries of rule-following will save us. It wont. The more America breaks, the more other nations will step in to fill the void. What if the dollar ceases to be the world reserve currency? Most Americans cant comprehend the benefits we gain from this status, or the economic and lifestyle pain well suffer if it goes away. Once its gone, its gone. Theres no going back. What if a debt ceiling fight takes us over the edge? That might be all it takes. And can anyone tell me with a straight face they trust the leaders in Congress as responsible stewards of the country to NOT take us over that cliff? Damn the consequences?

Congress has gotten used to passes and do-overs. But there are things that will break us, will fundamentally alter life as we know it, well below the apocalyptic threats of climate change or nuclear war, but a new era of real, actual, American decline (not the made up American decline BS used in election ads). And were so polarized, so used to choosing and accepting less than we deserve in our leaders, I fear well lower the bar and accept it.

B. laments the abandonment of rationalism:

As a healthcare provider recommending COVID vaccination to skeptical patients, we are now educated by the CDC and our medical organizations that the best way to do this is, dont try to convince them using facts. In a nutshell this is an example of what worries me the most. The abandonment of any effort to make difficult decisions using rationalism.

So instead of approaching these decisions by using as much science, math, and reason as we have availableand acknowledging that almost all difficult decisions need to be made using incomplete informationweve now moved to a faith-based system. We choose a source of information like a cable news network or a minister or a politician or an internet community. And then just believe whatever they say rather than trusting institutions, fact-checking, and content experts. When both sides do that, there is no room for either compromise or getting anyone to agree that they might be wrong (now or in the past). We are thus left with no ability to address complicated, difficult issues like climate change, budget deficits, entitlement programs, or healthcare reform.

Jill is thinking about income inequality:

I am particularly interested right now in the debate spawned by Matthew Stewarts The Birth of a New American Aristocracy, the 9.9%, who own more wealth than all other Americans put together, and are perpetuating wealth inequality like never before. I am surprised to find myself in this class, and pondering how to get more clarity about the nature of the problem that our emergence as a class represents, and what can be done about this.

Matt worries that we dont invest more in the quality of education for all:

If we want to stay a leading force in the world, we should prioritize having the best educated population. Right now it seems like we are being forced into an absurd debate over preventing kids from being groomed or indoctrinated. Its an argument against activity thats not occurring, doing damage to the teaching field, school boards, and the overall effectiveness of education. We could be spending time and resources to give young generations the best education available, but we arent. Its going to haunt our country and inhibit our ability to progress as a competitive economy.

What makes me optimistic is to see the independent thought of the younger Gen Z population. They seem to understand social media and information in a different way that I hope allows them to identify mis/disinformation more naturally than older generations. They have skills and talents which will allow them to be successful in new ways. Millennials are uniquely well educated as a generation and will offer a lot of value as leaders. I look forward to a world more generally controlled by Millennials and Gen Z.

Tony believes that were doomed by the attack on truth that he perceives:

When I was a student in the late 90s and early aughts at Evangelical colleges, we were terrified of postmodernism. Perhaps ironically, we now find ourselves in a cultural moment foretold by those Evangelicals, but for different reasons and with many of them on the other side of truth. The fact that charlatans and pathological liars are allowed unfettered access to airwaves and social media is disastrous. It works for an anarchic state perhaps but not for a functioning republic. What we are seeing now is the nightmare underbelly of democracy that the Founders tried to prevent by implementing certain checks and balances. I see no evidence that this experiment is leading in a direction other than failure.

L. has concerns about excessive questioning of everything, but finds hope at work:

Im a middle school educator, teaching social studies in the Bronx. What troubles me is the denigration of institutions. I dont just mean government. We as a society have questioned and doubted so much (on both the left AND the right) that the familiar groundings of societyfamily, education, commercebecome objects of constant suspicion.

Social media is a huge culprit in this: any medium that makes a fool an instant expert is a conduit for anarchy. However, I found hope in my classroom. We were discussing the difficult legacy of the Declaration of Independence. 41 slave owners were among the 56 signers of a document that stated all men are created equal. I asked if the flaws of these men invalidated the ideas in the document (an idea that gets wide circulation in critical studies). One by one, my students disagreed. They all said basically the same thing: the ideas are too important to throw away. They are ideas worth fighting for, ideas that should be what we as Americans should work towards every day. I almost cried.

Sophia fears an environment that is increasingly efficient, polluted, ugly, controlled, tamed, tracked; a culture in which children and adults are increasingly afraid, lonely, and anxious despite objective safety; and a culture in which people die after years of slow deterioration of mind and body, while she finds hope in genetic engineering; an explosion of beautiful art in the form of writing, television, movies, and fashion; an end to farm animal exploitation through the invention of lab grown meat; and assisted suicide legislation and more good death culture.

Like other readers, Isaac worries about social medias effect on society:

Social media as it exists today degrades human experience. I am fairly young but I dont use it. I believe the epidemics of anxiety, loneliness, and depression that are wrecking my generation are due in large part to the commercialization of social interaction. These platforms exploit human weakness and our tendency to believe things that we agree with, intensify in-group out-group thinking, and turn truth into a political football.

What worries me is that these platforms will remain central to all forms of public discourse, and that Americans will find it impossible to act as one people. We face numerous existential challenges. We cannot surmount them without a shared set of facts and values. I think that it is possible to create beneficial social mediathere are values to connectionbut that is not what we have today and unless there is a recognition that these businesses are sucking our attention dry at the expense of the things that matter most (love, compassion, truth, reason) we are going to be unable to surmount our challenges and I think we will be in an increasingly isolated, atomized, and alienating culture.

What gives me hope is this: America is a strong country. We have spent the last decade at least with no clear enemy, no clear purpose, and a pervasive need to self doubt and eat our own. If we play to our strengths, recognize the incredible gift of our democracy, our geography, and our people, then we could accomplish almost anything.

Errol fears that we are too pessimistic:

I worry that were entering a world of overcorrection.

I love this country, where you can break free of the worst and incorporate the best of the culture youve come from. That is one of the best ideas a society has ever had. But now mixing cultures is cultural appropriation and a bad thing. Weve allowed the most immigrants ever in the history of any government, yet weve somehow become the border wall country. Im not saying we are without serious problems, but we do do good and have a rich positive history as well. We invented airplanes and movies. We landed on the moon! These are pretty remarkable progressive steps for the species. The world is worse without the US in it, and while we can and should do better, it would be nice to acknowledge the good once in a while and to take a break from the constant negativity.

Martin worries about the degradation of local control:

My concern is that so many individuals, especially those in the current political class, are forgetting that we are a Federal Republic with a principles-based constitution underpinned by a liberal (in the classic, not political, sense) set of values. I guess you can ask, why does this matter?

In a Federal Republic a significant portion of decision-making can be pushed to local communities. What is unfortunate is that each time there is conflict between various layers of government our politicians in one party or the other seem to want to aggregate power farther from the citizenry. Over the past 20 years we have watched both California and Texas push for nationalization of their legislative priorities followed by the cry for states rights as soon the Federal government changed hands. And in both cases we have watched as these states have mandated behavior at the county, city and even school board level in conflict with local desires. As long as the principles enshrined in the 14th amendment ( nor deny to any person within its jurisdiction the equal protection of the laws) are met, federalism allows for a multitude of laboratories in which to innovate and learn. Just as none of us really think technological innovation should occur only in one location, we should not believe that of political innovation.

Michael is so worried that he has thought about where else he might move:

I am frankly terrified about the direction of the country. I have never felt this pessimistic about where we are heading. It appears we are in an endlessly polarized environment where there is no unity and little or no concern for anyone who is not in our tribe. As someone who has been a liberal democrat all my life, and has mostly, but not always, lived in the northeast US, I appreciate that to some extent I live in a bubble surrounded by like-minded people. But many of us pay attention to current events and my concern is shared by many. I just had lunch with a close friend yesterday, and we were talking about what other countries might be a more hospitable, less stressful place to live. I have had more than a few sleepless nights thinking about this.

What am I optimistic about? One thing that I find both reassuring and perhaps a source of optimism is that my three adult children seem far less troubled than I am. They are busy with careers, relationships, house hunting, etc. Maybe as someone who is semi-retired, I just have too much time to think about things. It is almost as if the best case scenario is that as the federal government becomes less empowered (due to the originalism of the Supreme Court), states will evolve separately and perhaps people will gravitate to states that are more welcoming to them. We would no longer be a united country (I think that train has left the station anyway), we would be in more of a cold civil war. The enormous downside of that, of course, would be a fractured response to International events. It appears we are headed toward a more conflictual world stage and having a fractured and ineffectual US would certainly not help.

For Eric, theres nothing to be pessimistic about but pessimism itself:

I actually dont worry that much about the direction of the country, but I do worry about issues with the country. The thing that worries me most is the popularization of the end-of-the-world framework, often seen in a religious context, being applied to American democracy. This concerns me, because, right now, this type of pessimism is broadly and simultaneously permeating both the left and the right. I cant think of a precedent for this. There are always fatalistic pockets of society, but American fatalism appears to have gone mainstream. Democracy is just an idea. It exists solely in our collective imagination. If enough of us stop believing its a good idea, then it wont withstand an organized assault.

This is a serious problem. But, as I said, Im not that worried. Weve been through divisive times before. We survived an actual bloody Civil War over the right to own humans, so weve fought it out over the most serious issue. I think its a strong precedent for success. And were seeing tons of participation in the allegedly rigged process, from both sides.

Were living through the first time in human history when we all hear the thoughts of anybody who wants to speak their thoughts out loud. And a lot of people (but not all) seem to want to speak. But sometimes we forget that talk is cheap. People say all kinds of things that they dont mean, especially from behind a keyboard, especially if theyre anonymous. There are people who say abhorrent things that they actually believe. But there are a lot of people who speak incredibly flippantly about all sorts of stuff who, when push-comes-to-shove, would be forced to admit they dont mean it. Just think of the tough guy talk some people use behind their keyboards, who are actually sad, pathetic wimps.

The freedom to say things inconsequentially via social media has dovetailed with the desire for attention and a perverse incentive structure that rewards extreme speech, so a lot of people appear disenchanted with American democracy, but theyre living their best lives thanks to it. Now, it may be the case that the insincere language reaches such a fever pitch that coming generations internalize it without realizing how performative it is, and then we could be screwed. But I think humans will adapt to a world with social media and will find solutions to the malaligned incentive structure. People will continue realizing that American democracy, for all its flaws, is still pretty awesome, and well keep improving it.

Thanks for your contributions. I read every one that you send. See you Wednesday.
