Establishing Workers’ Right Not to Hear Bosses’ Propaganda


The NLRB rules that management may not compel employees to attend its anti-union meetings.

Union members await a speech by President Biden in Philadelphia, November 1, 2024.

One of the many ways that employers intimidate workers from joining unions is via the captive-audience meeting, in which those workers are subjected to their boss’s arguments against their unionizing. Employers require their workers to attend these meetings; not attending may be, depending on the boss’s mood, grounds for being penalized, demoted, or even discharged.

Last week, the National Labor Relations Board ruled that such meetings violate the National Labor Relations Act, which was designed to give workers a free choice in deciding whether they wished to join a union. By requiring workers’ attendance at such meetings, the Board ruled, those workers’ choice became less free.

Over the past four decades, captive-audience meetings have become standard management practice when workers seek to join a union. They are a prominent feature in the Union Busting 101 courses that anti-union attorneys and consultants provide to their business clients, both big and small. Union organizers have no tool in their arsenal that can match it: Not only can they not compel workers to do anything, but they’re also forbidden from organizing within the worksite. This asymmetry, the NLRB ruled, runs counter to the letter and spirit of the NLRA.


More from Harold Meyerson

Captive-audience meetings have also come under attack on a different front. During the past two years, ten states have outlawed them. The first was Minnesota, where the ban was enacted in early 2023, shortly after Democrats gained control of both houses of the legislature and Gov. Tim Walz signed it into law. Eight other blue trifecta states quickly followed: California, Connecticut, Hawaii, Illinois, Maine, New York, Oregon, and Washington. And a ban on those meetings was part of an omnibus pro-worker ballot measure (which also included a hike in the minimum wage and the establishment of paid sick leave) that Alaska voters enacted.

Those states, of course, didn’t base their decisions on the NLRA, which is federal law, but more simply on trying to level the playing field between employers and employees. One argument for banning the meetings that I’ve heard from some labor lawyers is that compelling employees to attend those meetings violates workers’ freedom from speech, which is something like the B-side of the First Amendment. As management lawyers take these state laws to court, they’re sure to argue that the NLRA preempts the rights of the states to address this issue. That’s one more reason why last week’s NLRB decision is so important.

That said, the NLRB is the federal agency most subject to reversing its own rulings, depending on who the president is. The Board consists of three members nominated by the president and two by the opposition party, and while members’ terms are staggered, eventually the appointees of the new president outnumber the appointees of the old. That’s why, for instance, a ruling from the Obama-era Board that said that graduate students working at private universities as teaching and research assistants were employees and thus eligible for union membership and collective bargaining was struck down by the Trump-era Board and then reinstated by the Biden Board. In all likelihood, it will be struck down again once the Board is dominated by Trump’s appointees.


What makes this reversal unlike the previous ones is that it’s only in the past couple of years, since the Biden Board gave those grad students the green light, that many thousands of them have organized most of America’s leading private universities. (The NLRA only covers private-sector employees; the 48,000 University of California grad student/employees, for instance, have unionized and won contracts because California state law permits public employees to collectively bargain.) Should the newly unionized private universities (Harvard, Yale, MIT, Caltech, etc.) revoke their grad students’ union recognition and rescind their contracts, it shouldn’t come as a surprise if those students strike and the nation’s foremost universities come to a screeching halt.

How soon could Trump appointees dominate the Board? That may be up to the current lame-duck session of the Senate, which since June has had before it the renomination of Lauren McFerran, who under Biden has been the Board chair. If she is confirmed again, she would be part of the three-member pro-worker Board majority. Until their own majority expires at year’s end, Senate Democrats have pledged to keep ratifying the judicial nominees Biden has put before them, and have come under understandable pressure from labor to confirm McFerran as well. If they do, the next expiration of a pro-worker member’s term won’t come until 2026.

Some Democrats reportedly fear that Trump will simply fire all three Democrats if the Senate reconfirms McFerran, a move that is legally contestable (not that that would deter Trump). Then again, not confirming McFerran would also quickly give the Board over to Trump.

Under McFerran, and with the strong prodding of NLRB General Counsel Jennifer Abruzzo, the Biden Board has been the most committed to ensuring workers’ rights since Franklin Roosevelt’s. It has limited employers’ ability to delay union recognition elections, increased the payments employers must make to employees they illegally fired to deter organizing campaigns, and mandated more significant remedies (including compelling employers to enter collective bargaining with their workers’ union) when employers violate the NLRA in seeking to deter unionization. Eliminating captive-audience meetings is a capstone of sorts to the Board’s campaign to restore to American workers the rights they once enjoyed, before Republicans in the White House, Congress, statehouses, and the courts concluded that worker power was an inherent threat to capital and their campaign contributors. Even if those Republicans now taking power sweep away the Biden Board’s rulings, though, those rulings would be the starting point for the next iteration of worker rights when the Democrats, as they surely will, return to power themselves.

Quirks of Right-Wing Populism

Far-right populists do share some things with the left. But boss rule Trumps them all.



Looking for some dim silver linings, some progressives have made the accurate observation that some right-wing populists have criticisms of capitalism that mirror the left’s. They may be, if not useful idiots, occasional allies.

For instance, Robert F. Kennedy Jr. has criticized Big Food and Big Pharma. If he can just drop some of his more lunatic views, as secretary of HHS he might shine a useful spotlight and revise some bad industry practices.

Dr. Deborah Birx, COVID response coordinator during Trump’s first term, said Sunday she expects that Kennedy’s nomination will lead to illuminating discussions about public health. Speaking on CBS’s Face the Nation, she said, "I’m actually excited that in a Senate hearing he would bring forward his data and the questions that come from the senators would bring forth their data."

CBS showed a clip of Kennedy saying, "I’m just going to tell the cereal companies to take all the dyes out of their food. I’ll get processed food out of school lunch immediately. Ten percent of food stamps go to sugar drinks to, you know, sodas. We’re creating diabetes problem, and our kids are giving them food that’s poison, and I’m going to stop that."

Birx is actually a serious person. She served as Obama’s global AIDS coordinator. Could she be onto something?

The populist right also has mixed feelings about tech billionaire monopolies (Elon Musk and Peter Thiel excepted) because of their fundraising for Democrats and their socially liberal views. Our friend Matt Stoller published a startling item on the admiration of Matt Gaetz for FTC Chair Lina Khan, charmingly describing Gaetz as a "Khanservative."

As Stoller wrote, "Gaetz proudly calls himself a Lina Khan fan, and filed a brief with the conservative Fifth Circuit asserting that the Federal Trade Commission has the authority to ban non-compete agreements, and personally hosted her as a guest on a show on Newsmax to discuss how to get rid of ‘creepy’ commercial surveillance. He has praised the Biden Antitrust Division’s Jonathan Kanter’s work on Google."

Stoller also quoted Gaetz: "It is my belief that the number one threat to our liberty is big government. It is also my belief that the number two big threat to our liberty is big business, when big business is able to use the apparatus of government to wrap around its objectives."

This sounds hopeful, but Gaetz may well not get confirmed as attorney general. And if he does, he still has to answer to Trump, who could easily find antitrust officials with his own highly selective views of which monopoly abuses to go after and which to give a pass.

And while Kennedy does have some views that are critical of Big Food and Big Pharma, consider what happened on the food front over the weekend.

In the past, RFK Jr. has been highly critical of Trump’s diet. "The stuff that he eats is really, like, bad," he said. "Campaign food is always bad, but the food that goes onto that airplane is, like, just poison. You have a choice between—you don’t have the choice, you’re either given KFC or Big Macs. That’s, like, when you’re lucky, and then the rest of the stuff I consider kind of inedible."

Well, on Sunday, all the talk shows showed images of Trump forcing Kennedy to choke down a burger, fries, and a Coke.

The deeper problem with far-right populism is that the boss is the boss of bosses. Because far fringe appointees like Gaetz and Kennedy, if confirmed, will be entirely creatures of Trump’s whims, they will do what he says.

E.E. Cummings wrote in a poem, celebrating a brave conscientious objector named Olaf who was brutalized by his captors, declaring, "There is some shit I will not eat." That evidently does not describe RFK Jr.

Scientist proposes deducing commonality from complexity to resolve global challenges



Chinese Academy of Sciences Headquarters





Two topics are now drawing great attention from the global scientific community: shifting or advancing paradigms in science, and tackling global challenges such as the UN Sustainable Development Goals, climate change, and human health. However, do these two topics share fundamental and interrelated mechanisms? Are there laws common to complex systems in science, engineering, and society?

These questions have puzzled scientists for decades as they try to address complexities fundamentally.

In his recent Perspective published in the Proceedings of the Royal Society A on Nov. 13, Professor LI Jinghai from the Institute of Process Engineering of the Chinese Academy of Sciences summarized his four-decade study of these questions and outlined future directions for his work.

Inspired by the physical phenomenon of the coexistence and interaction between a gas-rich dilute phase and a solid-rich dense phase, with different physical mechanisms dominating the behavior for each phase in gas–solid fluidization, LI and his colleagues recognized an underlying compromise-in-competition (CIC) mechanism that exists between the two physically dominant mechanisms.

The CIC principle was then extended to formulate and understand other complex systems in many apparently disparate fields. It later evolved into the concept of Mesoscience, which can be used to explore the common principles at mesoscales of different levels of complexity.

“Through the concept of Mesoscience, we aim to explore the possible commonality among complexity in different fields,” said Professor LI, also a member of the Chinese Academy of Sciences.

In his Perspective, LI proposed future directions for identifying, developing, and applying the concept of Mesoscience, including extending its possible generality and applications to many different disciplines and fields such as analyzing challenging global issues and promoting CIC-informed AI.

In this way, many challenging problems in engineering—identified through their underlying mesoscale complexity—will be closely correlated with the development of future basic science, according to Professor LI.

The deduction of commonality from diversity will help to resolve global challenges, shift paradigms in science, and fill in gaps at the mesoscales of different levels of knowledge. However, diversity also produces difficulties and uncertainty.

“We believe that the concept of Mesoscience deserves global attention, particularly at a time when tackling challenges facing all humankind involves some common knowledge gaps most likely at mesoscales.” said Professor LI.

18 November 2024. Doha, Qatar —The World Innovation Summit for Health (WISH) – Qatar Foundation’s global healthcare initiative – featured a much-anticipated panel discussion on addressing the urgent need to implement palliative care based on the report, ‘Palliative Care: How can we respond to ten years of limited progress’, released alongside the summit.

The report’s main author, Professor Richard Harding, Director of the C. Saunders Institute of Palliative Care, said:

“Everybody in this room shares the same challenge: we have patients and family members who face progressive illnesses, who are living with unnecessary physical and psychological suffering. We have a challenge at the health system level…. And we know that there's a cost, with money being spent on non-beneficial treatments. In high-income countries, the one percent of people who die annually consume 10% of the health budget. So, we've got a major problem. The great thing is, we've got the solution. It's palliative care.”

Professor Richard Harding was joined on the panel by Dr. Rachel Clarke, award-winning author and palliative care doctor; Dr. Tala Al Taji, QF Alumni and Palliative care fellow at the University of Rochester; Dr. Asmus Hammerich, the Director for NCD and Mental Health for the Eastern Mediterranean Regional Office of the World Health Organization; Professor Dame Louise Robinson, Academic, General Practitioner (GP), and Professor of Primary Care and Ageing; and Dr. Emmanuel Luyirika, the Executive Director of African Palliative Care Association.

The panel agreed that if we are to tackle this global challenge, we need to provide more community-centered care and reframe our understanding of the term, emphasizing that it is a concept that includes -- but is not limited to -- end-of-life care.

As populations age and chronic conditions become more common, particularly in transitioning countries, the demand for effective care that alleviates suffering and enhances the quality of life—especially for those nearing the end of life—grows. The need for palliative care is expected to double by 2060.

The panel discussed in detail innovative and cost-effective recommendations to transform essential palliative care in the years to come and identified several key areas to focus on, including: empowering local communities with materials in locally spoken languages, supporting and enabling primary care doctors, increasing appropriate education and training at all levels, enabling research, advocating for better policies in this neglected healthcare area, and increasing literacy and reducing stigma in the general population.

Dr. Tala Al Taji emphasised the importance of understanding the religious and cultural context of patients: “I have found that culture and religion can shape somebody's willingness to go through treatment or desire to go through treatment. It can shape the decisions that they make at different stages of their illness, and it can even shape their decisions at the end of their lives. I think one of the core principles of palliative care is to preserve patient autonomy, and we cannot preserve patient autonomy without truly understanding the value system of a patient.”

Several of the panelists, including Dr. Clarke, spoke of their work in palliative care as a privilege.  Dr. Clarke said: “I strongly believe and see every day at work that there is always potential for goodness and beauty and love and compassion and meaning right up until the end of life, because dying is like living, it is a lived experience, and something we go through with people we love around us, if we're lucky, and that means there's always the potential for us as doctors and healthcare workers to make a difference.”

This year, WISH was opened in the presence of Her Highness Sheikha Moza bint Nasser, Chairperson of Qatar Foundation and founder of WISH. The opening ceremony, held at Qatar National Convention Centre in Doha, included speeches from Her Excellency Dr. Hanan Mohamed Al Kuwari, Qatar’s former Minister of Public Health; Lord Darzi of Denham, Executive Chair of WISH; and Christos Christou, President of Médecins Sans Frontières. 

The theme of WISH 2024 was ‘Humanizing Health: Conflict, Equity and Resilience’. It aims to highlight the need for innovation in health to support everyone, leaving nobody behind and building resilience, especially among vulnerable societies and in areas of armed conflict.

Ahead of the summit, WISH entered into a strategic partnership with the World Health Organization (WHO), collaborating on the development of a series of evidence-based reports and policy papers, as well as working with the United Nations’ health agency to develop a post-summit implementation strategy. 

The summit featured more than 200 experts in health speaking about evidence-based ideas and practices in healthcare innovation to address the world’s most urgent global health challenges.


 

Be humble: Pitt studies reveal how to increase perceived trustworthiness of scientists



University of Pittsburgh





How can scientists across climate science, medical and psychological topics foster the public’s trust in them and their science? Show that they are intellectually humble.

Those are some of the findings of two intellectually humble University of Pittsburgh scientists and their co-authors, using five separate studies totaling 2,034 participants in research published Nov. 18 in Nature Human Behaviour.

“Research has shown that having intellectual humility — which is an awareness that one’s knowledge or beliefs might be incomplete or wrong — is associated with engaging in more effortful and less biased information processing,” said Jonah Koetke, the principal author and a graduate student under co-author Karina Schumann, associate professor of psychology. “In this work, we wanted to flip the perspective and examine whether members of the public believe that scientists who are intellectually humble also produce more rigorous and trustworthy research.  

“Because it is so critical to the scientific process — for example, being aware of the limits of our knowledge, communicating the limitations of results, being willing to update beliefs — members of the public might be more likely to trust scientists who exhibit intellectual humility.”

The article, also co-authored by Shauna Bowes of Vanderbilt University and Nina Vaupotič of the University of Vienna, cited statistics showing how Americans reporting a great deal of confidence in scientists decreased by 10% from 2020 to 2021 (the last measured year at the time of the writing), to 29% overall. For hot-button topics, the confidence dips even lower — as evidenced by differing public perceptions amid the pandemic over lockdowns, social distancing, vaccines and more — despite the presence of evidence-based science affirming their effectiveness.

“These are anxiety-provoking times for people, and they feel uncertain about who to trust and which recommendations to follow,” Schumann said. “We wanted to know what can help people feel more confident putting their faith in scientists working to find solutions to some of the complex global challenges we are facing.”

This dilemma stood at the heart of their study: What are the factors “that legitimately promote or hinder trust” in science and scientists? The researchers measured perceived trustworthiness as having the qualities of expertise, benevolence (seeing scientists as people who pursue wellbeing for all), and integrity. They also measured how much people trusted the scientists’ research by asking about their willingness to learn more about the research and follow the scientists’ recommendations.

The researchers theorized that intellectual humility would be a key characteristic of scientists that guides how members of the public perceive them.

“When scientists fail to behave in ways that reflect intellectual humility, it might be especially detrimental and jarring, as it goes against both the fundamental norms of science and people’s expectations for how a responsible scientist should act,” the co-authors reasoned.

So they set out to research whether perceptions of scientists’ intellectual humility would influence people’s trust in scientists and their research.

Study 1: They asked 298 online participants from across the U.S. to think of scientists and rate them on their perceived intellectual humility. Participants also offered ratings of the perceived trustworthiness of scientists and of their belief in polarizing science topics such as climate change, vaccinations and genetically modified foods. In the end, the study showed correlational evidence that the more participants believed scientists were intellectually humble, the more they trusted scientists and believed in evidence-based science.

Study 2:  To better isolate the effects of intellectual humility on trust, they next tested their hypothesis by assigning 317 participants to read one of three “articles” about an ostensible scientist identified as a woman researching new treatments for long COVID-19 symptoms. The three “articles” described the scientist in ways that conveyed either low intellectual humility or high intellectual humility, or did not discuss characteristics related to intellectual humility (control condition). They found large effects on trust in the predicted direction, with participants reporting lower trust toward the scientist described as having low intellectual humility compared to the other two conditions. Participants in the low intellectual humility condition also reported less belief in the scientist’s research on the new treatment.

Study 3: Because questions surrounding gender perception were left unanswered in Study 2, the co-authors sought to examine the effect of a scientist’s gender identity on the public’s reactions to intellectual humility. They randomly assigned 369 participants to read an article about an ostensible psychological scientist studying why people should talk across political divides. They used the same three “article” designs as Study 2, but varied whether each described either a female or male scientist. Replicating Study 3, they again found large effects of intellectual humility on trust, as well as small-to-medium effects on belief in the research and whether participants would follow the scientist’s recommendations. The described gender of the scientist had no influence on the benefits of high vs. low intellectual humility on these outcomes.

Study 4:  To ensure that the benefits of perceived intellectual humility generalized to scientists of color, the co-authors next tested if participants were affected by the racial identity of the scientist. Some 371 participants were randomly assigned to read an “article” about an ostensible climate scientist testing the benefits of plant-rich diets for reducing global carbon emissions. In this new scientific context, the authors replicated the effects from the prior studies and also discovered a small-to-medium effect on participants’ desire to obtain further information about switching to a plant-rich diet — 36% people opted in to receive this information when the scientist was high in intellectual humility compared to 21% when the scientist was low in intellectual humility. Notably, as with gender, the described race of the scientist didn’t show an effect.

Study 5: In the final study, the authors set out to test an important question that remained: How can a scientist express they are intellectually humble when communicating their research to the public? The authors randomly assigned 679 participants in a census-matched sample to read one of four “interviews” with an ostensible scientist discussing the psychological benefits of taking a social-media break (not considered as polarizing as the previous study topics). These interviews included approaches like describing the methodological limitations of the research or giving credit to their graduate students. However, although the approaches were generally effective at increasing perceptions of intellectual humility, none of the communication strategies successfully increased perceptions of scientists’ trustworthiness and several even backfired by shaking people’s trust in the research. The authors humbly noted that they still don’t how scientists can communicate intellectual humility in ways that also builds trust.

“We still have a lot to learn about specific strategies scientists can use to display their intellectual humility in their public communications,” Koetke said. “This will be the focus of future work.”

For now, the research team came away feeling that the general public values intellectual humility.

“As a scientist, I felt incredibly encouraged by our findings,” Schumann said. “They suggest that the public understands that science isn’t about having all the answers; it's about asking the right questions, admitting what we don’t yet understand, and learning as we go. Although we still have much to discover about how scientists can authentically convey intellectual humility, we now know people sense that a lack of intellectual humility undermines the very aspects of science that make it valuable and rigorous. This is a great place to build from.”

Mediterranean Sea dropped during the Messinian Salinity Crisis – a major geological event that transformed the Mediterranean into a gigantic salt basin between 5.97 and 5.33 million years ago2.

Until now, the process by which a million cubic kilometres of salt accumulated in the Mediterranean basin over such a short period of time remained unknown. Thanks to analysis of the chlorine isotopes3 contained in salt extracted from the Mediterranean seabed, scientists have been able to identify the two phases of this extreme evaporation event. During the first phase, lasting approximately 35 thousand years, salt deposition occurred only in the eastern Mediterranean, triggered by the restriction of Mediterranean outflow to the Atlantic, in an otherwise brine-filled Mediterranean basin. During the second phase, salt accumulation occurred across the entire Mediterranean, driven by a rapid (< 10 thousand years) evaporative drawdown event during which sea-level dropped 1.7-2.1 km and ~0.85 km in the eastern and western Mediterranean, respectively. As a result, the Mediterranean Basin lost up to 70% of its water volume.

This spectacular fall in sea level is thought to have had consequences for both terrestrial fauna and the Mediterranean landscape – triggering localised volcanic eruptions due to unloading of Earth's crust, as well as generating global climatic effects due to the huge depression caused by the sea-level drawdown.

These results, published in Nature Communications on November 18, provide a better understanding of past extreme geological phenomena, the evolution of the Mediterranean region and successive global repercussions.

This work was supported by the European Union and the CNRS.

  2. This exceptional event covered the floor of the Mediterranean Sea with a layer of salt up to 3 km thick. Understanding the causes, consequences and environmental changes undergone by the Mediterranean region in response to the Messinian Salinity Crisis is a challenge that has mobilised the scientific community for decades.
  3. Analysis of the two stable chlorine isotopes (³⁷Cl and ³⁵Cl) made it possible to estimate the rate of salt accumulation and detect the drop in sea level.

Keeping the lights on and the pantry stocked: Ensuring water for energy and food production




Stanford University




new study, focused on a remote region of the Peruvian Andes where the waters of the Amazon originate, carries lessons for hydropower operators and farming communities worldwide: collaborating on sustainable land management is the best decision they can make for the long-term viability of their businesses and livelihoods. It also opens opportunities for restoration of degraded ecosystems. Research from the Stanford-based Natural Capital Project (NatCap) in Communications - Earth & the Environment integrates hydropower operations with watershed processes and climate projections in a novel, high-resolution modeling approach for the Huallaga River Basin, upstream of the Chaglla Dam. It provides a detailed picture of how climate change will increase water shortages, and points to investments in upstream reforestation and sustainable irrigation as the most effective paths toward meeting these challenges.

“This study is exciting because this is the first time climate change, hydropower, and land management practices have been put together in a robust decision-making approach,” said Zhaowei Ding, a postdoctoral researcher at NatCap and lead author on the paper. “In this region, people had looked at the relationship between hydropower and deforestation, or hydropower and food, but they were not connected. Now, we can show where water goes in the basin and we can optimize our management suggestions.”  

Climate-induced water shortages turn up the pressure

Despite serious social and environmental impacts, hydropower remains an important source of low-carbon energy in many parts of the world, including Latin America and Asia. However, hydropower dams cannot operate below a certain threshold of water flow. Reduced rainfall resulting from climate change will exacerbate the problem. So too will less rain during the growing season. Farmers upstream of hydropower plants will increasingly turn to irrigation to ensure their livelihoods, reducing the water available downstream. These changes will likely exacerbate conflict between the energy and agricultural sectors.

Waldo Lavado, a co-author and researcher at the National Service of Meteorology and Hydrology of Peru, noted that water resources in the Peruvian Andean-Amazonian basin are quite vulnerable to changes in land use and to climate change. “For the first time, this research scientifically documents possible projections of these changes – the first step to understanding the water-energy-food-ecosystem nexus in Peruvian basins with increasingly marked human influences.”

The researchers analyzed thousands of possible land and water use scenarios and found no win-win solutions for resolving tensions between water, energy, food, and ecosystems. Unplanned expansion of irrigation in this region could strongly impede the hydropower plant’s ability to function in the dry season, when hydropower is most valuable for the Peruvian power grid. At the same time, thousands of small-scale producers have long relied on rainfed agriculture for their food security and livelihoods, and for contributing to the national market. In this context, irrigation helps farmers mitigate increasing uncertainty. 

Nature offers damage control 

Nonetheless, the study found that impacts to both the energy and food sectors could be lessened using nature-based approaches. Investments in upstream reforestation and the creation of protected areas, by compensating farmers to plant trees instead of crops, would increase water availability for downstream hydropower by reducing irrigation needs. Forests also help retain soil, so this would lessen erosion and sedimentation, which impede dam operations. The modeling helped identify low-yield areas where farms use a lot of water for irrigation but aren’t producing similarly large crops – potentially prime locations for making this switch. This approach could be combined with investments in irrigation efficiency, like drip irrigation systems, in remaining crop production areas to maintain or increase local food production.

“This type of information can contribute to local stakeholders’ decision-making processes around development,” said Andrea Baudoin Farah, assistant professor at Colorado State University, former postdoctoral researcher with NatCap, and a co-author of the paper. “Local farmers and communities are well aware of the need to preserve the ecosystems and landscapes that sustain their production systems, but they face significant challenges in a changing environment.”

Baudoin Farah noted that Andean peasant communities have deep knowledge of the interconnections between ecosystems and food production, despite being historically relegated to the steepest, most marginal lands, and neglected in terms of supportive infrastructure. “Climate change is exacerbating their already-vulnerable livelihoods. Studies like this one point to the need to channel funds to support farmers in their efforts to conserve soils and implement sustainable production systems.”

Scaling the approach in other regions

“This study shows that natural capital approaches, in this case like investing in ecosystems to secure water supplies and reduce sedimentation, are the main lever at this nexus of food, energy, climate, and water,” said Tong Wu a senior scientist & associate director of the NatCap China Program, which collaborated on this research. “They are like the router through which all the different cables go through. It’s not just one solution – it’s the best solution.”

The researchers hope the study’s findings can motivate dialogue between hydropower operators and upstream stakeholders across Latin America. The largest dams in the world are located in Asia, so they are also engaged in ongoing conversations with key actors in the hydropower sector there about scaling up this nature-based approach to addressing the water crisis that is headed their way.

With climate change, the value of water will be higher and competition for it will be stronger. “If hydropower operators want to maintain their revenue, they will need to increase their investments in nature upstream of their dams,” said study senior author Rafael Schmitt, a lead scientist at NatCap and project lead.

“Our team’s modeling framework is an important step forward in defining eco-compensation mechanisms – like paying farmers not to farm, or where to implement protected areas – in a way that is science-based and robust, despite the great uncertainties introduced by future climate change,” Schmitt added.

The Natural Capital Project is based out of the Stanford Doerr School of Sustainability and its Woods Institute for the Environment, and the Stanford School of Humanities and Sciences. Other Stanford co-authors are Héctor Angarita, Jesse A. Goldstein, Natasha Batista, and Dave Fisher, all based at NatCap. Additional co-authors are Christian Montesinos Cáceres from the National Service of Meteorology and Hydrology of Peru (Servicio Nacional de Meteorología e Hidrología) and Hua Zheng with the Chinese Academy of Sciences.

Greg Liu is in his element using chemistry to tackle the plastics problem



Liu, a professor in the Department of Chemistry, has found a way to convert certain plastics into soaps and detergents, and now he is helping to explore business models that can profitably use his process on a much larger scale.

As an undergraduate student at Zhejiang University in eastern China, Greg Liu went with some of his classmates on a university-sponsored trip to tour a host of chemical industries within the area.

The tour gave students pursuing degrees in chemical engineering an opportunity to learn more about the manufacturing and production processes of chemicals within China at the time. Liu realized that day exactly what he wanted to do for a career – find ways to alleviate or stop the industry from polluting the environment.

“I realized that this was not going to be the sustainable way of our future. Pollution was everywhere, water, soil, road, you name it. Workers were in unbearable working conditions. I didn’t want to be in an environment like that, nor our future generations,” Liu said. “That basically drove me to think, ‘OK, I must pursue an advanced degree to change the way we work in the chemical industry.’”

Liu later came to the United States and earned his doctoral degree from the University of Wisconsin-Madison. Now, his zeal to use his knowledge of chemical engineering to create a more sustainable world has led to him developing a revolutionary way to deal with arguably one of the world’s most pressing issues — plastic pollution.

A long research project encompassing five or six years finally led to a breakthrough, with Liu, a professor within Virginia Tech’s Department of Chemistry housed in the College of Science, and his team of undergraduate and graduate students finding a way to convert certain plastics into soaps, detergents, lubricants, and other products. Liu has written an article about the process and the feasibility and commercialization of it that recently published in Nature Sustainability, a peer-reviewed scientific journal.

In simple terms, Liu’s system was two steps. It first involved using thermolysis, or breaking down a substance – in this case, plastic – by using heat. Plastic placed in a reactor built by Liu’s team and heated to between 650 and 750 degrees Fahrenheit broke down into chemical compounds, leaving a mixture of oil, gas, and residual solids. The key to this first step was breaking down the polypropylene and polyethylene molecules that make up plastic within a certain carbon range, and Liu and his team were able to accomplish this.

The residual solids left behind were minimal, and the gas could be captured and used as fuel. The oil, though, was the product of the most interest here.

During his research, Liu was able to functionalize, or change the chemistry, of the oil into molecules to be converted into soaps, detergents, lubricants, and other products.

“These materials are stable,” Liu said, holding up a vial of soap. “This vial of soap has been in my office for, I would say, a year already. … You could use it to wash your hands and dishes. We have used it to wash our lab glassware in the laboratory.”

The process, which took less than a day, led to almost zero air pollution output, thus offering clues to a desperately needed solution to a global problem. According to the United Nation’s website, the world produces 430 million tons of plastic each year, with the equivalent of 2,000 garbage trucks full of plastic dumped into oceans, rivers, and lakes each day.

Plastic pollution leads to an increased choking of marine wildlife, the damaging of soils, the poisoning of groundwater, and the causing of negative human health impacts. In addition, there are greenhouse gas emissions released into the air during production.

The United Nations expects plastic pollution to triple by 2060 if no action is taken. Unfortunately, according to the United Nation's website, less than 9 percent of plastic actually gets recycled – though there is a reason for that, according to Amanda Morris, the head of the Virginia Tech’s Department of Chemistry.

“We make plastics to last from the perspective that many of them have to hold a liquid inside them that you don’t want coming out of a bottle. So they have to be relatively strong materials,” Morris said. “The bonds that hold the polymer together and give us that strength and give us the properties of the bottles that we use are also really hard to break, and so it’s just trying to come up with ways to do it in an energy efficient manner where you get clean product.

“The other thing is that those polymers can degrade into many different things. Are there ways that we can get it to one specific product that then could actually be used downstream again? I think those are some of the things that we’ve struggled with.”

Liu and his team have come up with a way to break those bonds, but now potentially comes the hard part – scaling up the system and making it a continuous one, while, more importantly, making it cost effective.

His is the plight of many researchers. They often find solutions to issues, but those solutions can come with hefty price tags, often resulting in the solutions remaining on the sidelines. Liu said industries have expressed interest in upscaling this process, but any effort, energy, and investment needs to result in profitability.

Liu said he is seeking help from the community to test a business model. This involves securing capital needed to build a reactor to run continuously in his lab, or perhaps creating a private offsite start-up company to test the ramping up of his process. Yes, soap can be created from a few pieces of plastic, but can tons of plastic generate soaps and detergents profitably?

“There will be a lot of demand on our end to further derisk the process,” Liu said. “We have to derisk it so they [businesses] can see real value out of it, and they can potentially adopt it.

“My estimate is in the hundreds of thousands of dollars range to test this. The good thing is that we’re training talented students and postdocs in this lab right now. They will be the ones who can potentially carry on this process in the future. But we definitely need more resources, especially funds, to build reactors and test the reactors.”

Back-end challenges aside, Morris remains optimistic about Liu’s findings and their future impacts. She welcomes opportunities to publicize his efforts tackling the plastics problem and discussing the chemistry department’s efforts in meeting this challenge as part of Virginia Tech’s Global Distinction ambitions.

“I think that any time that we can make our science accessible to the broader public, including our alumni and friends, it’s incredibly beneficial,” Morris said. “It’s beneficial for them to see the impact that we’re having not just as Hokies, but also that they can have by investing further in the Virginia Tech mission.

“The goal is really to take Greg’s technology, make modifications based on what we understand fundamentally about the process, and then make it even more energy efficient and more beneficial to industry. The other thing is that Greg’s technology is for a few polymer classes [with a recycle code of 2, 4, and 5], so can we apply that to other polymer classes? Are there ways where we can increase the reach of the technology? That has me excited as well.”

Liu doesn’t view himself as a pioneer, although, in this case, he truly is a pioneer of converting plastic waste to soap. Instead, he views himself as someone contributing a small piece to the solution of a global problem that requires everyone’s diligence. He said he welcomes more involvement from the scientific and industrial community.

In other words, science needs more collaboration on this problem. The stakes are too high without it.

“It’s no longer enough to be like, ‘Oh, I can play with my cool chemistry in the laboratory, and I can magically generate something out of it, and then I’m good enough,’” Liu said. “That is surely cool, but that isn’t the real solution to the pressing problem of plastic crisis.

“I hope, down the road, we find a solution, and I hope plastic is no longer a problem to worry about. I hope, in time, society will take care of all these waste materials. We can generate useful chemicals and materials from waste, and hopefully we can close the loop of carbon and plastics. That is my dream. I believe we can achieve it, but it’s going to take a while. With everyone’s will, we will solve it.”

 

Nanoplastics can impair the effect of antibiotics

Minuscule particles of plastic are not only bad for the environment. A study led from Umeå University, Sweden, has shown that the so-called nanoplastics which enter the body also can impair the effect of antibiotic treatment. The results also indicate that the nanoplastics may lead to the development of antibiotic resistance. Even the indoor air in our homes contains high levels of nanoplastics from, among other things, nylon, which is particularly problematic.

"The results are alarming considering how common nanoplastics are and because effective antibiotics for many can be the difference between life and death," says Lukas Kenner, professor at the Department of Molecular Biology at Umeå University and one of the researchers who led the study.

Nanoplastics are plastic particles that are smaller than a thousandth of a millimetre. Due to their smallness, they can float freely in the air and have the ability to enter the body.

In the study, led not only by researchers in UmeÃ¥, but also by scientists based in Germany and Hungary, the authors have focused on how some of the most common nanoplastics interact with tetracycline, which is a common broad-spectrum antibiotic. It turned out that there was significant accumulation of the antibiotics on the surfaces of the nanoplastic particles. You could say that the nanoplastics absorb antibiotics. 

The nanoplastics in question come from common types of plastics such as polyethylene, polypropylene, polystyrene and nylon. They are commonly found in packaging and textiles. Indoor air contains about five times as much nanoplastics as outdoor air, partly due to particles released from textiles.

One risk that the researchers point out is that the binding to nanoplastics can lead to the antibiotics "hitchhiking" with the nanoplastic in the bloodstream and being transported to other places in the body than they are intended for. This can both reduce the targeted effect of the antibiotics and risk enabling the emergence of antibiotic-resistant bacteria. When antibiotics accumulate in unintended areas, sub-lethal doses can spur bacterial mutations, selecting for antibiotic-resistant strains.

The researchers used advanced computer models to analyze how the nanoplastics bind to tetracycline. It turned out that the bond was particularly strong to nylon –  one of the substances that is most abundant in nanoplastics in indoor air.

"Although more research is needed to shed light on the connections and possible measures, we can conclude from our results that nanoplastics are a health risk that should be taken more seriously," says Lukas Kenner.

The study, which is published in the scientific journal Scientific Reports, has been led by Lukas Kenner at UmeÃ¥ University, Barbara Kirchner at the University of Bonn in Germany and Oldamur Hollóczki at the University of Debrecen, Hungary. The sub-study on the binding of nanoplastics to antibiotics has been led by Nikola Zlatkov Kolev at the Department of Molecular Biology at UmeÃ¥ University. Lukas Kenner has recently taken up the position of visiting professor at the Department of Molecular Biology at UmeÃ¥ University and continues his research on nanoplastics and health effects.
