We tested if a specialised magnetic powder could remove microplastics from drinking water: the answer is yes

Source: The Conversation – Africa (2) – By Riona Indhur, Postdoctoral Research Fellow, Durban University of Technology

Microplastics are the crumbs of our plastic world, tiny pieces that come from bigger items breaking apart or from products like synthetic clothing and packaging. They’re now everywhere. Scientists estimate there are about 51 trillion of these particles floating in the world’s surface waters, and low levels have even been found in South African tap water.

That’s worrying because these particles can carry chemicals and bad bacteria, get eaten by fish and other wildlife, and may end up in our bodies.

We’re water scientists who are looking for ways to solve this problem. In a recent study, we tested a practical fix: two “magnetic cleaning powders” that can attach onto microplastics in water; the combined clumps can then be pulled out using a magnet. These materials are called magnetic nanocomposites (think: very fine powders with special surfaces).

The idea is simple: mix a small dose of powder into the water, let it attract and attach to microplastics, and then use a strong magnet to remove the powder-plastic clusters, leaving cleaner water behind.

Around the world, researchers have tried many different methods to capture microplastics, but our study is among the first to show that magnetic nanocomposites can work effectively not only under laboratory conditions but also in real-world samples, including municipal wastewater and drinking water.

This is the first study to use these specific nanomaterials for microplastic removal, proving both their high efficiency and their practical potential. Most existing filters struggle to catch the smallest plastics, the ones most harmful to health and the environment. The next step is to test these powders on a larger scale and develop simple, affordable systems that households and water treatment plants can use.

How well do the powders work?

In our research we found that the powders were able to remove up to 96% of small polyethylene and 92% of polystyrene particles from purified water. When we tried the same approach in both drinking water and water coming out of a municipal wastewater treatment plant, the results were just as strong. In drinking water the removal was about 94% and in treated wastewater the removal was up to 92%.

Another finding from this study is that the size of the plastic particles matters. The smaller the microplastic, the easier it is for the powders to attach to it, because tiny particles can reach more of the powder’s special “sticky” surface. We saw very good results for small plastics (hundreds of micrometres), but bigger particles (3-5 millimetres) were hardly removed at all. This is because they don’t mix with the powder as well and there’s less surface for the powder to attach onto.

In everyday terms, these magnetic powders are excellent for the small microplastics that are hardest to catch with normal filters.

Now for the big question: why do the powders attach to plastic? Think of it as being like tiny magnets. The powder and the plastics have special surfaces. The powder has parts that are sticky for plastics. This stickiness happens because of different kinds of forces. The plastic and powders have opposite charges which pull them together or allow them to stick together.

The key point is that the powders are engineered or specifically made to grab onto plastics so that microplastics naturally cling to them in water.

Once the powders attach onto the microplastics, we use a strong magnet (magnetic force: 250kg) to pull the powder–plastic clumps out of the water. The plastics are then separated from the powder by washing and filtration, dried, and weighed. This allows us to check how much plastic was removed. The separated powders are regenerated and reused, while the plastics are safely discarded, preventing them from re-entering the water.

We also looked at real-world questions: can you reuse the powders? And are they safe? The powders themselves are made from safe, lab-engineered materials: tiny sheets of carbon and boron nitride (a material also found in cosmetics and coatings) that are coated with magnetic iron nanoparticles. This makes them stable in water, and easy to pull out with a magnet after they’ve captured the microplastics.

After three rounds of use, the tested powders were effective in removing plastics up to 80%. That means you don’t need a new batch of powder every time, which is important for keeping costs down. Treating 1,000 litres of water with this method costs about US$41 (R763), making it competitive with many existing treatment options.

For safety, we tested the filtered powder (the “filtrate”) on plant growth. The results showed minimal to no toxicity, as three different plants were able to grow well in the presence of the filtrate. This is a strong sign that the method is environmentally friendly when used as intended.

What does this study mean for households and cities?

In the short term, magnetic powders could be built into small cartridges or filter units that attach to household or community water systems, helping remove microplastics before the water is used for drinking or cooking.

But the bigger picture is just as important. Microplastics are not only a South African problem but are also a global pollutant that crosses borders through rivers, oceans, and even the air we breathe. Low-cost, scalable solutions such as magnetic powders can make a real difference in resource-limited settings, where advanced filtration systems are too expensive or impractical.

Looking ahead, further work will focus on scaling up the method, testing it under more diverse water conditions, and designing simple, affordable devices that households or treatment plants can adopt.

In short: this specialised magnetic powder can tackle a tiny pollutant with big consequences. With sensible engineering and careful recovery, magnetic nanocomposites offer a promising, practical path to clean water while protecting the ecosystem from microplastic pollution.

Child malnutrition in Kenya: AI model can forecast rates six months before they become critical

Source: The Conversation – Africa (2) – By Laura Ferguson, Associate Professor, Population and Public Health Sciences, University of Southern California

Globally, nearly half of the deaths of children under five years are linked to malnutrition. In Kenya, it’s the leading cause of illness and death among children.

Children with malnutrition typically show signs of recent and severe weight loss. They may also have swollen ankles and feet. Acute malnutrition among children is usually the result of eating insufficient food or having infectious diseases, especially diarrhoea.

Acute malnutrition weakens a child’s immune system. This can lead to increased susceptibility to infectious diseases like pneumonia. It can also cause more severe illness and an increased risk of death.

Currently, the Kenyan national response to malnutrition, implemented by the ministry of health, is based on historical trends of malnutrition. This means that if cases of malnutrition have been reported in a certain month, the ministry anticipates a repeat during a similar month in subsequent years. Currently, no statistical modelling guides responses, which has limited their accuracy.

The health ministry has collected monthly data on nutrition-related indicators and other health conditions for many years.

Our multi-disciplinary team set out to explore whether we could use this data to help forecast where, geographically, child malnutrition was likely to occur in the near future. We were aiming for a more accurate forecast than the existing method.

We developed a machine learning model to forecast acute malnutrition among children in Kenya. A machine learning model is a type of mathematical model that, once “trained” on an existing data set, can make predictions of future outcomes. We used existing data and improved forecasting capabilities by including complementary data sources, such as satellite imagery that provides an indicator of crop health.

We found that machine learning-based models consistently outperformed existing platforms used to forecast malnutrition rates in Kenya. And we found that models with satellite-based features worked even better.

Our results demonstrate the ability of machine learning models to more accurately forecast malnutrition in Kenya up to six months ahead of time from a variety of indicators.

If we have advance knowledge of where malnutrition is likely to be high, scarce resources can be allocated to these high-risk areas in a timely manner to try to prevent children from becoming malnourished.

How we did it

We used clinical data from the Kenya Health Information System. This included data on diarrhoea treatment and low birth weight. We collected data on children who visited a health facility who met the definition of being acutely malnourished, among other relevant clinical indicators.

Given that food insecurity is a key driver of acute malnutrition, we also incorporated data reflecting crop activity into our models. We used a NASA satellite to look at gross primary productivity, which measures the rate at which plants convert solar energy into chemical energy. This provides a coarse indicator of crop health and productivity. Lower average rates can be an early indication of food scarcity.

We tested several methods and models for forecasting malnutrition risk among children in Kenya using data collected from January 2019 to February 2024.

The gradient boosting machine learning model – trained on previous acute malnutrition outcomes and gross primary productivity measurements – turned out to be the most effective model for forecasting acute malnutrition among children.

This model can forecast where and at what prevalence level acute malnutrition among children is likely to occur in one month’s time with 89% accuracy.

All the models we developed performed well where the prevalence of acute child malnutrition was expected to be at more than 30%, for instance in northern and eastern Kenya, which have dry climates. However, when the prevalence was less than 15%, for instance in western and central Kenya, only the machine learning models were able to forecast with good accuracy.

This higher accuracy is achieved because the models use additional information on multiple clinical factors. They can, therefore, find more complex relationships.

Implications

Current efforts to predict acute malnutrition among children rely only on historical knowledge of malnutrition patterns. We found these forecasts were less accurate than our models.

Our models leverage historical malnutrition patterns, as well as clinical indicators and satellite-based indicators.

The forecasting performance of our models is also better than other similar data-based modelling efforts published by other researchers.

As resources for health and nutrition shrink, improved targeting to the areas of highest need is critical. Treating acute malnutrition can save a child’s life.

Prevention of malnutrition promotes children’s full psychological and physical development.

What needs to happen next

Making these data from diverse sources available through a dashboard could inform decision-making. Responders could get six months to intervene where they are most needed.

We have developed a prototype dashboard to create visualisations of what responders would be able to see based on our model’s subcounty-level forecasts. We are currently working with the Kenyan ministry of health and Amref Health Africa, a health development NGO, to ensure that the dashboard is available to local decision-makers and stakeholders. It is regularly updated with the most current data and new forecasts.

We are also working with our partners to refine the dashboard to meet the needs of the end users and promote its use in national decision-making on responses to acute malnutrition among children. We’re tracking the impacts of this work.

Throughout this process, it will be important to strengthen the capacity of our partners to manage, update and use the model and dashboard. This will promote local responsiveness, ownership and sustainability.

Scaling up

The Kenya Health Information System relies on the District Health Information System 2 (DHIS2). This is an open source software platform. It is currently used by over 80 low- and middle-income countries. The satellite data that we used in our models is also available in all of these countries.

If we can secure additional funding, we plan to expand our work geographically and to other areas of health. We’ve also made our code publicly available, which allows anyone to use it and replicate our work in other countries where child malnutrition is a public health challenge.

Furthermore, our model proves that DHIS2 data, despite challenges with its completeness and quality, can be used in machine learning models to inform public health responses. This work could be adapted to address public health issues beyond malnutrition, like changes in patterns of infectious diseases due to climate change.

Toronto Blue Jays: Amid Canada-U.S. tensions, ‘Canada’s team’ takes a run at America’s pastime

Source: The Conversation – Canada – By Noah Eliot Vanderhoeven, PhD Candidate, Political Science, Western University

Amid threats from United States President Donald Trump to make Canada the 51st state, the Toronto Blue Jays’ season started with protocols aimed at avoiding booing during the American national anthem and the removal of someone wearing a “Canada is not for sale hat” at the ballpark.

Nonetheless, the Blue Jays are still being heavily marketed as “Canada’s team” as they square off against the New York Yankees, America’s most storied baseball team.

Why do the Blue Jays frame themselves as not just Toronto’s team, but Canada’s? And is their current post-season run their biggest and most important opportunity in years to fully establish themselves as representing all of Canada?

Truly Canada’s team?

The Jays serving as Canada’s team may make sense since they’re the only Canadian team currently playing in Major League Baseball (MLB). But to some Canadians, positioning the Jays as the nation’s team may not sit well.

After all, for baseball fans in Québec, memories of the now-defunct Montreal Expos still loom large.

For fans closer to the Windsor-Detroit border, the Detroit Tigers are a more proximate and accessible team.

Finally, some British Columbia MLB enthusiasts — despite the trips Blue Jays fans make to take over T-Mobile Park when the Blue Jays play the Seattle Marinersstill opt to support the Mariners since the team is so much closer than the Blue Jays are in Toronto.

What all this means is that to some Canadian baseball fans, the Blue Jays aren’t really Canada’s team — they’re just Toronto’s.

Huge market

It’s unsurprising that the Toronto Blue Jays organization, owned by Rogers Communications — “proud owner of Canada’s team” — is intent on framing the squad this way because it provides a substantial financial boon. The Jays benefit greatly from being Canada’s team by compelling baseball fans from across the country to attend their games, and most importantly, to watch them on television.

Despite playing north of the border and earning revenues in the weaker Canadian dollar, the Jays operate in one of MLB’s largest markets — Toronto — and can also market to fans across the country. That gives them the largest geographical market in professional baseball — an entire nation.

This massive audience contributes to equally massive television ratings, even at a time when most MLB teams are struggling for regional television revenues. Being “Canada’s team” has also allowed the Blue Jays to spend competitively over the past 10 years and operate a Top 5 payroll, as they have in 2025, alongside other teams in huge markets like Los Angeles and New York.

Cross-border trash-talking

As the series with the Yankees continues, Prime Minister Mark Carney met with Trump to discuss trade, tariffs and security. The meeting, held just days after Trump made yet another veiled annexation threat, reportedly went well.

But the ongoing backdrop of tense relations between the U.S. and Canada is perhaps echoed by some of the commentary about both teams.

Early in the season, the Yankees’ play-by-play man, Michael Kay, called Toronto “not a first-place team” despite the Blue Jays having just passed the Yankees for first place in the American League East.

In September, Jays colour-commentator and former catcher, Buck Martinez, said that the Yankees were “not a good team.”

Also in September, a Baltimore Orioles television analyst, Brian Roberts, questioned how well Canadians understood baseball, leading to the Blue Jays themselves defending the baseball intelligence of their fans.

There was even a popular hoax online about Trump not inviting the Blue Jays to the White House should they win the World Series — an invite he’s extended to many championship teams in American sports leagues.

Stoking Canadian nationalism

Ultimately, the Blue Jays ended up winning the American League East, guaranteeing the Jays a home-field advantage against the Yankees. Blue Jays players and their manager, John Schneider, have spoken of the intense atmosphere Blue Jays fans create for their opponents and how the team draws on the support of the entire nation of Canada.

The Jays’ success so far in the post-season in this current political moment — as Trump is once again making veiled threats about making Canada the 51st state during tense trade negotiations — presents the Blue Jays with perhaps their best opportunity to fulfil their role as Canada’s team.

In a season defined by rivalry, politics and national pride, the Blue Jays are proving that even America’s pastime can become a canvas for Canadian nationalism.

Geothermal energy has huge potential to generate clean power – including from used oil and gas wells

As energy use rises and the planet warms, you might have dreamed of an energy source that works 24/7, rain or shine, quietly powering homes, industries and even entire cities without the ups and downs of solar or wind – and with little contribution to climate change.

The promise of new engineering techniques for geothermal energy – heat from the Earth itself – has attracted rising levels of investment to this reliable, low-emission power source that can provide continuous electricity almost anywhere on the planet. That includes ways to harness geothermal energy from idle or abandoned oil and gas wells. In the first quarter of 2025, North American geothermal installations attracted US$1.7 billion in public funding – compared with $2 billion for all of 2024, which itself was a significant increase from previous years, according to an industry analysis from consulting firm Wood Mackenzie.

As an exploration geophysicist and energy engineer, I’ve studied geothermal systems’ resource potential and operational trade-offs firsthand. From the investment and technological advances I’m seeing, I believe geothermal energy is poised to become a significant contributor to the energy mix in the U.S. and around the world, especially when integrated with other renewable sources.

A May 2025 assessment by the U.S. Geological Survey found that geothermal sources just in the Great Basin, a region that encompasses Nevada and parts of neighboring states, have the potential to meet as much as 10% of the electricity demand of the whole nation – and even more as technology to harness geothermal energy advances. And the International Energy Agency estimates that by 2050, geothermal energy could provide as much as 15% of the world’s electricity needs.

Why geothermal energy is unique

Geothermal energy taps into heat beneath the Earth’s surface to generate electricity or provide direct heating. Unlike solar or wind, it never stops. It runs around the clock, providing consistent, reliable power with closed-loop water systems and few emissions.

Geothermal is capable of providing significant quantities of energy. For instance, Fervo Energy’s Cape Station project in Utah is reportedly on track to deliver 100 megawatts of baseload, carbon-free geothermal power by 2026. That’s less than the amount of power generated by the average coal plant in the U.S., but more than the average natural gas plant produces.

But the project, estimated to cost $1.1 billion, is not complete. When complete in 2028, the station is projected to deliver 500 megawatts of electricity. That amount is 100 megawatts more than its original goal without additional drilling, thanks to various technical improvements since the project broke ground.

And geothermal energy is becoming economically competitive. By 2035, according to the International Energy Agency, technical advances could mean energy from enhanced geothermal systems could cost as little as $50 per megawatt-hour, a price competitive with other renewable sources.

Types of geothermal energy

There are several ways to get energy from deep within the Earth.

Hydrothermal systems tap into underground hot water and steam to generate electricity. These resources are concentrated in geologically active areas where heat, water and permeable rock naturally coincide. In the U.S., that’s generally California, Nevada and Utah. Internationally, most hydrothermal energy is in Iceland and the Philippines.

Some hydrothermal facilities, such as Larderello in Italy, have operated for over a century, proving the technology’s long-term viability. Others in New Zealand and the U.S. have been running since the late 1950s and early 1960s.

Enhanced geothermal systems effectively create electricity-generating hydrothermal processes just about anywhere on the planet. In places where there is not enough water in the ground or where the rock is too dense to move heat naturally, these installations drill deep holes and inject fluid into the hot rocks, creating new fractures and opening existing ones, much like hydraulic fracturing for oil and gas production.

A system like this uses more than one well. In one, it pumps cold water down, which collects heat from the rocks and then is pumped back up through another well, where the heat drives turbines. In recent years, academic and corporate research has dramatically improved drilling speed and lowered costs.

Ground source heat pumps do not require drilling holes as deep, but instead take advantage of the fact that the Earth’s temperature is relatively stable just below the surface, even just 6 or 8 feet down (1.8 to 2.4 meters) – and it’s hotter hundreds of feet lower.

These systems don’t generate electricity but rather circulate fluid in underground pipes, exchanging heat with the soil, extracting warmth from the ground in winter and transferring warmth to the ground in summer. These systems are similar but more efficient than air-source heat pumps, sometimes called minisplits, which are becoming widespread across the U.S. for heating and cooling. Geothermal heat pump systems can serve individual homes, commercial buildings and even neighborhood or business developments.

Direct-use applications also don’t generate electricity but rather use the geothermal heat directly. Farmers heat greenhouses and dry crops; aquaculture facilities maintain optimal water temperatures; industrial operations use the heat to dehydrate food, cure concrete or other energy-intensive processes. Worldwide, these applications now deliver over 100,000 megawatts of thermal capacity. Some geothermal fluids contain valuable minerals; lithium concentrations in the groundwater of California’s Salton Sea region could potentially supply battery manufacturers. Federal judges are reviewing a proposal to do just that, as well as legal challenges to it.

Researchers are finding new ways to use geothermal resources, too. Some are using underground rock formations to store energy as heat when consumer demand is low and use it to produce electricity when demand rises.

Some geothermal power stations can adjust their output to meet demand, rather than running continuously at maximum capacity.

Geothermal sources are also making other renewable-energy projects more effective. Pairing geothermal energy with solar and wind resources and battery storage are increasing the reliability of above-ground renewable power in Texas, among other places.

And geothermal energy can power clean hydrogen production as well as energy-intensive efforts to physically remove carbon dioxide from the atmosphere, as is happening in Iceland.

A diagram shows pipes extending down from the surface of the ground, pushing cold water into hot rocks below, and drawing hot water back up.
Enhanced geothermal systems can be built almost anywhere and can take advantage of existing wells to save the time and money of drilling new holes deep into the ground.

Geothermal potential in the US and worldwide

Currently, the U.S. has about 3.9 gigawatts of installed geothermal capacity, mostly in the West. That’s about 0.4% of current U.S. energy production, but the amount of available energy is much larger, according to federal and international engineering assessments.

And converting abandoned oil and gas wells for enhanced geothermal systems could significantly increase the amount of energy available and its geographic spread.

One example is happening in Beaver County, in the southwestern part of Utah. Once a struggling rural community, it now hosts multiple geothermal plants that are being developed to both demonstrate the potential and to supply electricity to customers as far away as California.

Those projects include repurposing idle oil or gas wells, which is relatively straightforward: Engineers identify wells that reach deep, hot rock formations and circulate water or another fluid in a closed loop to capture heat to generate electricity or provide direct heating. This method does not require drilling new wells, which significantly reduces setup costs and environmental disruption and accelerates deployment.

There are as many as 4 million abandoned oil and gas wells across the U.S., some of which could shift from being fossil fuel infrastructure into opportunities for clean energy.

Challenges and trade-offs

Geothermal energy is not without technical, environmental and economic hurdles.

Drilling is expensive, and conventional systems need specific geological conditions. Enhanced systems, using hydraulic fracturing, risk causing earthquakes.

Overall emissions are low from geothermal systems, though the systems can release hydrogen sulfide, a corrosive gas that is toxic to humans and can contribute to respiratory irritation. But modern geothermal plants use abatement systems that can capture up to 99.9% of hydrogen sulfide before it enters the atmosphere.

And the systems do use water, though closed-loop systems can minimize consumption.

Building geothermal power stations does require significant investment, but its ability to deliver energy over the long term can offset many of these costs. Projects like those undertaken by Fervo Energy show that government subsidies are no longer necessary for a project to get funded, built and begin generating energy.

Despite its challenges, geothermal energy’s reliability, low emissions and scalability make it a vital complement to solar and wind – and a cornerstone of a stable, low-carbon energy future.

Seasonal allergies may increase suicide risk – new research

The study found that deaths by suicide rose by up to 7.4% on high-pollen days. Grace Cary/Moment via Getty Images

Seasonal allergies – triggered by pollen – appear to make deaths by suicide more likely. Our findings, published in the Journal of Health Economics, show that minor physical health conditions like mild seasonal allergies, previously thought not to be an immediate trigger of suicide, are indeed a risk factor.

To evaluate the link between seasonal allergies and suicide, my co-authors and I combined daily pollen measurements with daily suicide counts across 34 U.S. metropolitan areas.

Because both pollen and suicide are sensitive to weather conditions, we carefully accounted for temperature, rainfall and wind. We also controlled for differences in local climate and plant life, since pollen levels vary by region, and for seasonal averages that might otherwise obscure results. This allowed us to compare suicide counts on days with unexpectedly high pollen to days with little or none in the same county.

The results were striking. Relative to days with no or low levels of pollen, we found that deaths by suicide rose by 5.5% when pollen levels are moderate and 7.4% when levels are high. The increase was even larger among people with a known history of mental health conditions or treatment. We also showed that on high-pollen days, residents of affected areas experience more depressive symptoms and exhaustion.

Our analysis suggests that allergies exacerbate existing vulnerabilities, pushing some people toward crisis. We suspect that sleep disruption is the link between allergies and suicide rates.

Why it matters

More than 80 million Americans experience seasonal allergies each year.

Symptoms include sneezing, congestion, itchy eyes and scratchy throat. Most people experiencing these symptoms feel sluggish during the day and sleep poorly at night. Allergy sufferers might not realize, however, that these symptoms reduce alertness and cognitive functioning – some of the factors that can worsen mental health and increase vulnerability to suicidal thoughts and behaviors.

Suicide rates have been growing steadily in the past two decades, by 37% between 2000 and 2018. According to the Centers for Disease Control and Prevention, more than 49,000 Americans died by suicide in 2022, and over 616,000 visited emergency departments for self-harm injuries.

Although socioeconomic and demographic factors are the most important predictors of suicide, much less is known about its short-term triggers. Our study adds to growing evidence that the environment – including something as natural as pollen – can influence mental health risks.

This issue is likely to become more urgent as the climate changes. Rising temperatures lengthen pollen seasons and increase pollen volume. Over the past two decades, pollen seasons have grown in both intensity and duration, and projections suggest they will continue to worsen.

That means more people will experience stronger allergy symptoms, with ripple effects not only for physical health but also for sleep, mood and mental well-being.

What we still don’t know

Despite the scale of the problem, there are no national systems in the U.S. to consistently measure and communicate pollen levels. Most communities lack reliable forecasts and alert systems that would allow vulnerable people to take precautions. This gap limits both prevention and research.

Our study focused on metropolitan areas where pollen and death counts were available, but we cannot yet generalize to rural areas. That is a concern because rural communities often face greater shortages in mental health care and pharmacy access – and have seen rising suicide rates over the past decade.

What’s next

For people who are already receiving mental health care, recognizing and treating seasonal allergies is a key part of self-care.

Over-the-counter medications can be highly effective at reducing symptoms.

More broadly, people should be aware that during peak allergy season, reduced alertness, sleep disruptions and mood fluctuations may place an increased burden on their mental health, in addition to the allergy symptoms.

In terms of policy, improving pollen monitoring and public communication could help people anticipate high-risk days. Such infrastructure would also support further research, particularly in rural areas where data is currently lacking. Our next step, supported by the American Foundation for Suicide Prevention, is to examine the impact of pollen on rural communities.

The Research Brief is a short take on interesting academic work.

Why higher ed’s AI rush could put corporate interests over public service and independence

Source: The Conversation – USA (2) – By Chris Wegemer, Postdoctoral researcher, University of California, Los Angeles

Artificial intelligence technology has begun to transform higher education, raising a new set of profound questions about the role of universities in society. A string of high-profile corporate partnerships reflect how universities are embracing AI technology.

The University of Florida began assembling one of the fastest university supercomputers through a collaboration with Nvidia encompassing AI infrastructure, research support and curriculum development. Princeton launched the New Jersey AI Hub with Microsoft, CoreWeave and the state government, which will house AI startups on university-owned land under a Princeton director. Meanwhile, the California State University system partnered with OpenAI to provide ChatGPT Edu to all students and faculty, branding itself as “the first AI-powered university system in the United States.”

As a social scientist who studies educational technology and organizational partnerships, I view these collaborations as part of a decades-long shift toward the “corporatization” of higher education – where universities have become increasingly market-driven, aligning their priorities, culture and governance structures with industry partners.

I see the rise of generative AI as accelerating this trend, which risks undermining higher education’s autonomy and public service mission. Examining the underlying organizational forces that shape the future of higher education can shed light on how AI challenges universities’ traditional principles – and how they might resist corporate influence.

The rise of corporate partnerships

Over the past 50 years, private sector support for university research has increased tenfold, outpacing overall growth in higher education research spending. A pivotal shift came in 1980, when universities gained the right to retain intellectual property from federally funded research. This made commercialization of university research far easier. Over time, corporate involvement pushed university research toward commercial needs and increasingly exposed universities to the profit motive.

But partnerships haven’t just brought in money for universities; they’ve reinforced a shift toward closer alignment with industry. Universities expanded dramatically in the second half of the 20th century to meet companies’ demand for skilled labor, further coupling higher education to market incentives.

After decades of growth, however, university enrollment peaked in 2010, partly due to demographics, and the decline is projected to continue. Meanwhile, competition from training programs offered by tech companies has been growing, and federal funding has been slashed under President Donald Trump.

As colleges continue to close at record rates, the imperative to attract tuition dollars and research grants increasingly dictates institutional priorities. I argue that universities risk sidelining research that serves the public interest by looking toward corporate funding and partnerships to fill the gaps.

In my view, the shift away from public-good scholarship to monetizable content and services shaped by external industry partners jeopardizes the academic freedom and intellectual stewardship that once anchored the mission of higher education. For example, under financial constraints, university administrators may be inclined to overlook glaring value misalignments between their public mission and the commercial objectives of AI firms.

The forces driving universities’ AI initiatives

At many universities, AI adoption and the turn toward corporate collaborations are driven by more than economic vulnerabilities. The broad range of partnerships with AI companies across higher education can provide insight into the deeper dynamics at work.

Differences in AI partnerships are emerging around long-standing divides between types of institutions. Stanford’s Institute for Human-Centered AI can be interpreted as an attempt to steer global discourse on ethical AI while preserving human-led research as a marker of elite prestige. Meanwhile, AI initiatives at institutions with a strong focus on teaching and accessibility, such as California State University and Arizona State University, appear to prioritize efficiency in learning outcomes and workforce development.

This underscores how AI partnerships are not guided by market incentives alone. Before universities grew into multibillion-dollar businesses, their decision-making was primarily driven by markers of intellectual prestige, such as scholarly excellence and faculty reputation. Universities largely held a monopoly over knowledge production and served as the primary gatekeepers of intellectual legitimacy, until the digital revolution dramatically decentralized access to knowledge and its production. Universities now coexist in – and increasingly compete with – a crowded, complex ecosystem of companies and organizations that produce original research.

Generative AI represents a powerful new mode of knowledge production and synthesis, which further threatens to upend traditional forms of scholarship. Confronted with challenges to their authority, universities may attempt to preserve their elite intellectual status by rushing into partnerships with AI companies eager to capture the higher education market.

My interpretation is that economic pressures and the pursuit of prestige may be converging to reinforce a technocratic approach to higher education, where university decision-making is primarily guided by performance metrics and corporate-style governance rather than the public interest.

A purposeful path forward

The evolution of higher education in response to AI has brought long-standing debates about the purpose of universities to the forefront of public discourse. Decades of corporatization has helped fuel widespread “mission sprawl” and conflicting institutional goals across higher education. Consistent with organizational theory, ambiguity about universities’ role in society could lead many institutions to become increasingly susceptible to corporate co-optation, political interference and eventual collapse.

Although partnerships between universities and corporations can advance research and support students, corporate norms and academic principles are inherently distinct. And at many universities the process through which differences in institutional values are surfaced and reconciled is unclear, especially as AI initiatives have often sidestepped democratic faculty governance.

The recent surge in AI partnerships puts in plain view the growing dominance of market forces in higher education. As universities continue to adopt AI technologies, the consequences for intellectual freedom, democratic decision-making and commitment to the public good will become an increasingly pressing question.

Winning a bidding war isn’t always a win, research on 14 million home sales shows

Source: The Conversation – USA (2) – By Soon Hyeok Choi, Assistant Professor of Real Estate Finance, Rochester Institute of Technology

In today’s hot housing market, winning a bidding war can feel like a triumph. But my research shows it often comes with a catch: Homebuyers who win bidding wars tend to experience a “winner’s curse,” systematically overpaying for their new homes.

I’m a real estate economist, and my colleagues and I analyzed nearly 14 million home sales in 30 U.S. states over roughly two decades. We found that people who paid more than the asking price for their homes – a reliable sign of a bidding war – were more likely to default on their mortgages and saw significantly weaker returns.

How much weaker? On average, homebuyers who won bidding wars saw annual returns that were about 1.3 percentage points lower than those who didn’t, we found. We specifically looked at “unlevered” returns – basically, the returns you’d get if you bought the home outright with cash, without factoring in a mortgage.

Since the typical homeowner in our sample held a property for 6.3 years before selling it, this translates to about an 8.2% overpayment. Bidding-war winners were also 1.9 percentage points likelier to default.

Perhaps that loss would be worth it to someone who absolutely loves the property – but we found that homebuyers who purchase after a bidding war are also faster to resell. This suggests their overpayment is based less on enduring affection and more on bidding-war fever.

We also found that the effects of the winner’s curse – lower home appreciation and higher default rates – are stronger in places where bidding wars are more common. One example is my hometown of Rochester, New York, which has become a bidding-war hot spot in recent years.

Who bears the brunt? Lower-income, Black and Hispanic buyers are more likely to overpay in bidding wars, we found, making them more likely to suffer from the winner’s curse. This suggests that hot housing markets can worsen inequality.

Why it matters

While housing is the largest single form of wealth Americans own, past research on the winner’s curse mostly dealt with land auctions and company mergers – not the nation’s roughly 76 million owner-occupied, single-family homes. Our work is the first to show the direct evidence of the winner’s curse in residential housing markets.

This matters now because the housing market is cooling. Those who bought in the post-pandemic housing market and listed their homes in 2025 are already facing the risk of selling at a loss. Because this risk falls disproportionately on Black and Hispanic homebuyers, it could further widen the wealth gap.

By one measure, foreclosures are up 18% year over year. If the brunt of these losses falls on lower-income or otherwise vulnerable homeowners, the result could be an increase in housing insecurity and homelessness.

The good news is that the winner’s curse may be preventable. Better resources to prepare first-time homebuyers and comprehensive financial education related to mortgages and debt could help.

What still isn’t known

It’s possible more transparent bidding processes – or even formal auction systems for popular homes – could better inform prospective buyers and help them stave off the temptation of overpayment. Should the U.S. require real estate brokers or banks to caution their clients to think twice before going above the asking price? Or would that be unfair to sellers? Experimental research on these points would be useful.

Finally, our research focuses on the U.S. housing market. Whether the winner’s curse afflicts buyers in other countries remains an open question.

The Research Brief is a short take on interesting academic work.

Jane Fonda, other stars, revive the Committee for the First Amendment – a group that emerged when the anti-communist panic came for Hollywood

Jane Fonda is joining forces with more than 500 celebrities and Hollywood heavyweights to defend free speech.

The membership roll already includes scores of famous actors like Jamie Lee Curtis, Viola Davis, Whoopi Goldberg, Pedro Pascal, Natalie Portman and Michael Keaton. Successful directors like Spike Lee and Ben Stiller have signed on, along with singer and actress Barbra Streisand and pop star and songwriter Billie Eilish.

Fonda, a star who has championed progressive causes since the 1970s, explained when she announced the group’s new edition on Oct. 1, 2025, that the effort isn’t really new. Instead, it marks the relaunch of the Committee for the First Amendment, an organization her father, actor Henry Fonda, had belonged to.

The original Committee for the First Amendment was formed in October 1947 at a time when the U.S. government worried that there were communists in Hollywood who were putting left-wing propaganda into the movies.

Hearings divided Hollywood

The attack on Hollywood started when a bipartisan congressional committee held a series of highly publicized hearings in 1947 on what it said was the “communist infiltration of the motion picture industry.”

The House Un-American Activities Committee, known as HUAC, invited 23 “friendly” anti-communist witnesses to testify.

Ayn Rand, a Russian-born novelist and screenwriter who hated communism, was one of the witnesses. She testified that the 1944 MGM movie “Song of Russia” showed clean, well-dressed, happy peasants, which she said was a sanitized, propagandized version of life in the USSR.

Another movie that came under suspicion was “It’s a Wonderful Life.” The FBI complained that the 1946 blockbuster, which starred Jimmy Stewart as a broken man who learns the true value of his life, “deliberately maligned the upper classes” with its negative portrayal of Mr. Potter, the town’s richest man.

The HUAC hearings continued for a decade and divided Hollywood. The committee’s interrogators demanded that people turn on each other and “name names.” Due to these hearings, as well as an anti-communist publication called Red Channels, hundreds of screenwriters, directors, producers, actors and musicians were fired or blacklisted for having ties to liberal groups.

Fighting back

The HUAC hearings brought Hollywood stars and the flashbulbs of the nation’s press corps to Capitol Hill. Conservative screen idols like Gary Cooper testified that communism wasn’t “on the level.”

Friendly witnesses, like Rand and Cooper, were allowed to read prepared statements and to speak for as long as they liked. Such courtesies were not granted to the 10 “unfriendly” witnesses – the suspected communists who became known as the “Hollywood 10.”

Screenwriter John Howard Lawson was the first of the Hollywood 10 to testify. Lawson, after refusing to answer if he was a communist or not, was shouted down by Rep. J. Parnell Thomas, a New Jersey Republican who served as HUAC chair. After Lawson was removed from the courtroom, HUAC’s chief investigator, Robert Stripling, read detailed evidence of Lawson’s communist affiliations.

Prominent Hollywood liberals understood that these hearings were an attack on free speech, free assembly and other rights guaranteed by the First Amendment.

Ira Gershwin, the lyricist known for his hit show tunes such as “I Got Rhythm” and “They Can’t Take That Away From Me,” hosted the first gathering of the Committee for the First Amendment at his Beverly Hills mansion. Attendees included Judy Garland, Humphrey Bogart, Lauren Bacall and Gene Kelly.

The committee quickly raised US$13,000 – the equivalent of $188,000 today – and chartered an airplane to Washington. Upon their arrival in the capital, they marched and spoke out in support of the Hollywood 10. Next, they produced a radio broadcast, “Hollywood Fights Back,” as a defense of the rights of Americans to write, produce, act in and see whatever movies they pleased.

The committee released an initial statement with 35 signatories. A few months later, it published a pamphlet with more than 300 additional names supporting the effort.

Purging Hollywood

If you’ve never heard of that committee, or if you only learned about it recently when the new version made headlines, you’re not alone. The group fizzled out almost as quickly as it had mobilized.

Bogart, perhaps its most famous member, soon retracted his support for the Hollywood 10, saying in March 1948 that he regretted his trip to Washington.

I’m no Communist,” the “Casablanca” star declared in a widely circulated statement.

Two crucial developments kneecapped the committee. First, the HUAC cited the Hollywood 10 for contempt of Congress. They were later tried in court and convicted of that crime. They eventually served prison time.

Also, studio executives drafted new hiring policies for the movie industry. Later known as the “Waldorf declaration” because the meeting took place in the Waldorf-Astoria hotel in Manhattan, the studio heads announced that the Hollywood 10 would be fired and banned from any studio, and that all the studios would agree to fire and ban any known communists.

Over the next decade, hundreds more stars and other key players in the entertainment industry were fired, purged and blacklisted in what became known as the blacklist era.

I’m a professor of English and film studies, and I’m writing a book about progressive films made during those years. The original committee’s members were mainly leftists and liberals whose careers survived the political pressures to root them out of show business.

The Committee for the First Amendment ultimately failed to protect the Hollywood 10 from professional attacks or incarceration, nor did it prevent hundreds of others from being blacklisted.

Bad timing

But I don’t believe that the original Committee for the First Amendment was destined to fail.

The Hollywood 10’s legal strategy, rooted in the First Amendment, reflected the hope that their convictions might be eventually overturned by the Supreme Court.

Unluckily, however, Frank Murphy and Wiley Blount Rutledge, two of the court’s most liberal justices, died before the appeal of the first two Hollywood 10 convictions could reach them.

After President Harry Truman replaced them, the Supreme Court declined to hear the appeals. Most of the Hollywood 10 served prison sentences between 1950 and 1951.

Why bother?

Given that the Committee for the First Amendment failed to protect Hollywood from conservative repression in the 1940s and 1950s, why would anyone revive it?

One reason is that there are parallels between the blacklist era and today.

For example, the Trump administration is trying to get comedians who poke fun at him kicked off the air, as evidenced by talk show host Jimmy Kimmel being temporarily pulled off the air.

Hollywood has also seen a surge in labor organizing. Many members of the new Committee for the First Amendment were on the front lines of the screenwriters and actors strikes of 2023.

Finally, this fight is arguably worth waging. Most Americans see the First Amendment as enshrining valuable rights. An October 2025 Marist poll found that 4 in 5 Americans think the U.S. is restricting First Amendment freedoms too much.

Americans still debate whether or not it was right to fire and blacklist Hollywood’s suspected communists. While many see the HUAC hearings as a travesty, others defend the House committee and the anti-communist fervor that inspired it.

‘The Pajama Game,’ a hit movie made in the 1950s, featured a fight by workers for higher pay.

Resilience and silence

Many look at the blacklist era as a time of capitulation by progressives in the face of repression. While there’s some validity to these claims, I’ve found that many progressive filmmakers also banded together, using allegory and other creative techniques to make movies with progressive – sometimes radical – messages.

Take “The Pajama Game,” for example. It’s a musical comedy about labor trouble in a pajama factory. While the film is a sexy, frothy romp, on the one hand, the film also casts Doris Day as Babe, a feisty union steward. In “Racing with the Clock,” workers sing about the pressure they feel to speed up the pace of their labor.

Scenes include workers organizing a slowdown, sabotaging machinery and going on strike. The last word spoken in the film is “solidarity.”

To me, the revival of the Committee for the First Amendment draws attention to the dangers implicit in efforts to muzzle writers, artists and filmmakers.

“Silence the artist, and you silence the most articulate voice the people have,” the actress Katherine Hepburn said in May 1947 in a speech written for her by Dalton Trumbo, one of the Hollywood 10. “Destroy culture and you destroy one of the strongest sources of inspiration from which a people can draw strength to fight for a better life.”

“Cambia lo superficial, cambia también lo profundo, cambia el modo de pensar, cambia todo en este mundo”.

Con este fragmento de la canción de Mercedes Sosa “Todo cambia” arrancaba el artículo ganador del Premio Luis Felipe Torrente de Divulgación sobre Medicina y Salud Fundación Lilly-The Conversation, un penetrante análisis sobre la validez de los testamentos vitales en los individuos aquejados por una demencia. “¿Existen cambios tan radicales que hagan que una persona deje de ser ella misma?”, se pregunta y hace preguntarnos su autor, Luis Espericueta, de la Universidad de Granada.

Entre las 132 candidaturas que se han presentado al certamen, dirigido a investigadores, doctorandos y docentes universitarios menores de 35 años, las propuestas han sido muy diversas en fondo y forma, como ilustra el tono más desenfadado del segundo premio: Partirse de risa: el origen científico del ja, ja, ja. Marta Calderón García, de la Universidad Miguel Hernández, nos invita a embarcarnos en un amenísimo viaje por los pormenores psicológicos, neurobiológicos y culturales de la risa humana.

Lo que no cambia es la voluntad de claridad y la pasión por la ciencia que también transmiten los ocho artículos finalistas, publicados durante estos últimos tres meses en The Conversation. Sus autores, por ejemplo, son capaces de situarnos en un ring (la placenta) donde libran un trascendental combate los genes paternos y maternos durante el desarrollo de feto; o de imaginar a las células mandándose mensajes de WhastApp (las vesículas extracelulares), como si una película de Pixar se tratara.

Queda, por tanto, demostrado que las metáforas constituyen una poderosa herramienta para hacer divulgación. Encontramos otro exponente de su buen uso en el artículo Neurohambruna: cómo la escasez de comida reprograma a los hijos de la guerra, donde se compara el cuerpo de las embarazadas con un canal de noticias: “todo lo que ocurre afuera –lo que la madre come, cómo se siente, etc.– se traduce en mensajes químicos que informan al bebé sobre el entorno donde crecerá”, escribe la autora. Y sin salir de la biomedicina de vanguardia, también hemos aprendido que las células madre cancerígenas son “como brasas escondidas, invisibles pero activas, esperando el momento justo para arder otra vez”.

Además, gracias a esta variopinta antología podrá ponerse al día de las últimas novedades en materia farmacológica –los medicamentos biosimilares y el papel de los excipientes en los fármacos– o averiguar si puede considerarse como “normal” algún consumo de alcohol.

Y, por supuesto, no podía faltar el gran tema de nuestro tiempo: el artículo ¿Se fiaría del criterio de ChatGPT para su diagnóstico médico? Por si acaso, busque una segunda opinión pondera con sentido común los pros y contras del uso de la inteligencia artificial en el ámbito de la salud. Porque como cantaba Mercedes Sosa, “cambia el modo de pensar, cambia todo en este mundo”, y necesitamos más que nunca voces autorizadas que nos iluminen en estos tiempos de furia y ruido.

P. D. En memoria de Luis Felipe Torrente, que nos dejó hace poco más de un año y que desde esta quinta edición honra con su nombre al Premio. Su magisterio sigue siendo una brújula para todos quienes hacemos The Conversation.

Feliz lectura.

La troublante actualité du nouvel album de Woody Guthrie, sorti 58 ans après sa mort

Source: The Conversation – in French – By Daniele Curci, PhD Candidate in International and American History, University of Florence

Sorti cet été, l’album posthume de Woody Guthrie, figure emblématique de la musique folk des années 1940-1960, résonne puissamment avec la situation actuelle des États-Unis : plusieurs des titres qu’il contient, consacrés à l’expulsion de migrants mexicains, à une justice raciste ou encore aux injustices économiques, auraient pu être écrits ces derniers mois…


Le 14 août est sorti Woody at Home, Vol.1 & 2, le nouvel album de Woody Guthrie (1912-1967), probablement l’artiste folk américain le plus influent, auteur de la célèbre « This Land Is Your Land » (1940), qui dans cet album est proposée avec de nouveaux vers.

L’album contient des chansons – certaines déjà connues, d’autres inédites – que Guthrie enregistra avec un magnétophone offert par Howie Richmond, son éditeur, entre 1951 et 1952 et qui sont désormais publiées grâce à une nouvelle technologie qui a permis d’en améliorer la qualité sonore.

« Deportee »

La parution de l’album a été précédée par celle du single « Deportee (Plane Wreck at Los Gatos) », une chanson dont on ne connaissait jusqu’ici que le texte, que Guthrie écrivit en référence à un épisode survenu le 28 janvier 1948, lorsqu’un avion transportant des travailleurs saisonniers mexicains, de retour au Mexique, s’écrasa dans le canyon de Los Gatos (Californie), provoquant la mort de tous les passagers.

Un choix qui n’est pas anodin, comme l’a expliqué Nora Guthrie – l’une des filles du folk singer, cofondatrice des Woody Guthrie Archives et longtemps conservatrice de l’héritage politico-artistique de son père – lors d’un entretien au Smithsonian Magazine, dans lequel elle a souligné combien le message de son père reste actuel, au vu des expulsions opérées par l’administration de Donald Trump et, plus généralement, de ses tendances autoritaires, un thème déjà présent dans « Biggest Thing That Man Has Ever Done », écrite pendant la guerre contre l’Allemagne nazie.

Tout cela montre la vitalité de Woody Guthrie aux États-Unis. On assiste à un processus constant d’actualisation et de redéfinition de la figure de Guthrie et de son héritage artistique, qui ne prend pas toujours en compte le radicalisme du chanteur, mais qui en accentue parfois le patriotisme.

Un exemple en est l’histoire de « This Land Is Your Land » : de la chanson existent des versions comportant des vers critiques de la propriété privée, et d’autres sans ces vers. Dans sa première version, « This Land » est devenue presque un hymne non officiel des États-Unis et, au fil des années, a été utilisée dans des contextes politiques différents, donnant parfois lieu à des appropriations et des réinterprétations politiques, comme en 1960, lorsqu’elle fut jouée à la convention républicaine qui investit Richard Nixon comme candidat à la présidence ou, en 1988, lorsque George H. W. Bush utilisa la même chanson pour sa campagne électorale.

Guthrie lut le compte rendu de la tragédie du 28 janvier 1948 dans un journal, horrifié de constater que les travailleurs n’étaient pas appelés par leur nom, mais par le terme péjoratif de « deportees ».

Ce célèbre cliché pris par la photographe Dorothea Lange en Californie, en 1936, intitulé « Migrant Mother », montre Florence Thompson, 32 ans, alors mère de sept enfants, native de l’Oklahoma et venue dans le Golden State chercher du travail.

Dans leur histoire, Guthrie vit des parallèles avec les expériences vécues dans les années 1930 par les « Oakies », originaires de l’Oklahoma, appauvris par les tempêtes de sable (dust bowls) et par des années de crise socio-économique, qui se déplaçaient vers la Californie en quête d’un avenir meilleur. C’était un « Goin’ Down The Road », selon le titre d’une chanson de Guthrie, où ce « down » signifiait aussi la tristesse de devoir prendre la route, avec toutes les incertitudes et les difficultés qui s’annonçaient, parce qu’il n’y avait pas d’alternative – et, en effet, le titre complet se terminait par « Feeling Bad ».

Parmi les difficultés rencontrées par les Oakies et les Mexicains, il y avait aussi le racisme et la pauvreté face à l’abondance des champs de fruits, comme lorsque les Mexicains se retrouvaient à cueillir des fruits qui pourrissaient sur les arbres (« The crops are all in and the peaches are rotting ») pour des salaires qui leur permettaient à peine de survivre (« To pay all their money to wade back again »).

Et, en effet, dans « Deportee », d’où sont extraites ces deux citations, Guthrie demandait avec provocation :

« Is this the best way we can grow our big orchards ?
Is this the best way we can grow our good fruit ?
To fall like dry leaves to rot on my topsoil
And be called by no name except “deportees” ? »

Est-ce la meilleure façon de cultiver nos grands vergers ?
Est-ce la meilleure façon de cultiver nos bons fruits ?
Tomber comme des feuilles mortes pour pourrir sur ma terre arable
Et n’être appelés que par le nom de « déportés » ?

Visions de l’Amérique et radicalisme

« We come with the dust and we go with the wind », chantait Guthrie dans « Pastures of Plenty » (1941, également présente dans Woody at Home), l’hymne qu’il écrivit pour les migrants du Sud-Ouest, dénonçant l’indifférence et l’invisibilité qui permettaient l’exploitation des travailleurs.

Guthrie, de cette manière, mesurait l’écart qui séparait la réalité du pays de la réalisation de ses promesses et de ses aspirations. Dans le langage politique des États-Unis, le terme « America » désigne la projection mythique, de rêve, de projet de vie qui entrelace l’histoire de l’individu avec celle de la Nation. En ce sens, pour Guthrie, les tragédies étaient aussi une question collective permettant de dénoncer la façon dont une minorité (les riches capitalistes) privait la majorité (les travailleurs) de ses droits et de son bien-être.

La vision politique de Guthrie devait beaucoup au fait qu’il avait grandi dans l’Oklahoma des années 1920 et 1930, où l’influence du populisme agraire de type jeffersonien – la vision d’une république agraire inspirée par Thomas Jefferson, fondée sur la possession équitable de la terre entre ses citoyens – restait très ancrée, et proche du Populist Party, un parti de la dernière décennie du XIXe siècle qui critiquait ceux qui gouvernaient les institutions et défendait les intérêts du monde agricole.

C’est également dans ce cadre qu’il faut situer le radicalisme guthrien qui prit forme dans les années 1930 et 1940, périodes où les discussions sur l’état de santé de la démocratie américaine étaient nombreuses et où le New Deal de Franklin Delano Roosevelt cherchait à revitaliser le concept de peuple, érodé par des années de crise économique et de profonds changements sociaux.

Guthrie apporta sa contribution en soutenant le Parti communiste et, à différentes étapes, le New Deal, dans la lignée du syndicat anarcho-communiste des Industrial Workers of the World (IWW) dont il avait repris l’idée selon laquelle la musique pouvait être un outil important de la militance. Dans le Parti, Guthrie voyait le ciment idéologique ; dans le syndicat, l’outil d’organisation des masses, car ce n’est qu’à travers l’union – un terme disposant d’un double sens dont Guthrie a joué à plusieurs reprises : syndicat et union des opprimés – qu’on parviendrait à un monde socialisant et syndicalisé.

« White America ? »

L’engagement de Guthrie visait également à surmonter les discriminations raciales. Ce n’était pas chose acquise pour le fils d’un homme que l’on dit avoir été membre du Ku Klux Klan et fervent anticommuniste, qui avait probablement participé à un lynchage en 1911.

D’ailleurs, le même Woody, à son arrivée en Californie dans la seconde moitié des années 1930, portait avec lui un héritage raciste que l’on retrouve dans certaines chansons comme dans la version raciste de « Run, Nigger Run », une chanson populaire dans le Sud que Guthrie chanta à la radio, dans le cadre de sa propre émission, en 1937. Après cela, Guthrie reçut une lettre d’une auditrice noire exprimant tout son ressentiment quant à l’utilisation du terme « nigger » par le chanteur. Guthrie fut tellement touché qu’il lut la lettre à la radio en s’excusant.

Il entreprit alors un processus de remise en question de lui-même et de ce qu’il croyait être les États-Unis, allant jusqu’à dénoncer la ségrégation et les distorsions du système judiciaire qui protégeaient les Blancs et emprisonnaient volontiers les Noirs. Ces thèmes se retrouvent dans « Buoy Bells from Trenton », également présente dans « Woody at Home », qui se réfère à l’affaire des Trenton Six : en 1948, six Noirs de Trenton (New Jersey) furent condamnés pour le meurtre d’un Blanc, par un jury composé uniquement de Blancs, malgré le témoignage de certaines personnes ayant vu d’autres individus sur les lieux du crime.

« Buoy Bells from Trenton » a probablement été incluse dans l’album pour la lecture qu’on peut en faire sur les abus de pouvoir et sur les « New Jim Crow », expression qui fait écho aux lois Jim Crow (fin XIXe–1965). Celles-ci imposaient dans les États du Sud la ségrégation raciale, légitimée par l’arrêt Plessy v. Ferguson (1896) de la Cour suprême, qui consacrait le principe « séparés mais égaux », avant d’être abolies par l’arrêt Brown v. Board of Education (1954), le Civil Rights Act (1964) et le Voting Rights Act (1965).

Popularisée par Michelle Alexander dans le livre The New Jim Crow (2010), la formule désigne le système contemporain de contrôle racial à travers les politiques pénales et l’incarcération de masse : en 2022, les Afro-Américains représentaient 32 % des détenus d’État et fédéraux condamnés, alors qu’ils ne constituent que 12 % de la population états-unienne, chiffre sur lequel plusieurs études récentes insistent. Cette chanson peut ainsi être relue, comme le suggère Nora Guthrie, comme une critique du racisme persistant, sous des formes institutionnelles mais aussi plus diffuses. Un exemple, là encore, de la vitalité de Guthrie et de la manière dont l’art ne s’arrête pas au moment de sa publication, mais devient un phénomène historique de long terme.
