What began as a straightforward question from one water-quality advocate has morphed into a high-stakes battle over an oil pipeline at the highest levels of the U.S. government – with implications that go far beyond the fate of a technical legal conflict.

The question arose after a 2010 Enbridge Energy oil spill in Michigan. The advocate asked what other Michigan waterways were at risk from crude oil spills. But in the wake of, among other issues, two ships doing damage to an underwater section of another Enbridge oil pipeline, the conflict has now come all the way to the U.S. Supreme Court.

On Feb. 24, 2026, the justices will hear oral arguments and thereafter deliberate about the future of Enbridge Energy’s Line 5 oil pipeline, which runs through Michigan and Wisconsin.

As a water policy scholar with a focus on the Great Lakes, I have participated directly in the Line 5 debate as a gubernatorial appointee to an advisory board, as well as analyzed its implications. I see this moment in the Supreme Court as one layer of a complex debate that Line 5 has stirred up about states’ rights, Indigenous rights and the future of the fossil fuel economy.

Enbridge Energy vs. Dana Nessel

The actual issue in front of the Supreme Court is procedural: In 2019, Michigan Attorney General Dana Nessel sued Enbridge in a Michigan state court, seeking to shut down the pipeline, alleging “violations of the public-trust doctrine, common-law public nuisance, and the Michigan Environmental Protection Act.” Federal law allowed Enbridge to seek to move the case to federal court within 30 days of the initial filing.

Enbridge did not do so, but the Canada-based multinational company has since argued that it still should be allowed to deal with the case in federal court, as it is doing in a similar case brought by Michigan Gov. Gretchen Whitmer in 2020.

The specific question before the Supreme Court is a very technical legal one: Even though Enbridge failed to request the move to federal court in a timely way, should that prevent Enbridge from moving it later?

A sensitive waterway

There is no debate that Line 5’s crossing of the Straits of Mackinac – which separate Michigan’s Upper and Lower Peninsulas right where Lakes Michigan and Huron meet – lies within Michigan’s territorial boundaries.

The lawsuits from Nessel and Whitmer are attempting to stop Enbridge from operating the pipeline in this sensitive area of the Great Lakes.

The risks became clearer to the public when a ship’s anchor struck the underwater pipeline in 2018 and another ship damaged one of the pipe’s supports in 2020. In the 2018 incident, some fluid – not crude oil – leaked into the lake water.

But Enbridge is refusing to shut the pipeline down. The company says the dispute belongs in federal court because state laws and regulations generally do not apply to this pipeline, which carries mostly Canadian oil to mostly Canadian refineries, using Michigan and the Great Lakes as a shortcut. Enbridge maintains that a treaty with Canada supersedes state authority.

The ruling from the Supreme Court will likely be narrow and procedural. However, all parties seem to agree that the decision will also have much wider consequences, including being a key determinant and signal of states’ rights to protect their waterways and other natural resources in the face of industry opposition.

Bad River Band vs. Enbridge Energy

Meanwhile, in Wisconsin, the Line 5 oil pipeline passes through the reservation of the Bad River Band of Lake Superior Chippewa, and the pending legal outcome in a separate federal court case is well beyond procedural.

The band revoked Enbridge’s easement in 2013, but Enbridge has refused to remove the pipeline, so – after years of failed negotiations – the Bad River Band sued in 2019.

U.S. District Judge William Conley ruled in 2023 that Enbridge had been trespassing for 10 years and awarded US$3 million in damage payments. Conley gave Enbridge until June 2026 to find an alternative route around the Bad River Band’s land, or shut the pipeline down.

As this date approaches with no clear resolution in sight, the Trump administration joined Enbridge in seeking to reverse that decision and keep Line 5 open. While Conley’s decision is being contested by both Enbridge and the Bad River Band in an appeals court one level below the U.S. Supreme Court, the status of the pipeline during this legal process is very much in question.

Line 5 cannot operate without the Bad River Band reservation section, but the deeper issue is about Indigenous peoples’ rights to control their own lands and future on reservations. If Enbridge wins, many analysts believe that Indigenous rights to self-determination on reservations will be significantly eroded.

Attempts to reroute

Enbridge has a two-pronged strategy to save Line 5 from decommissioning: fight in the courts against the state of Michigan and the Bad River Band, while simultaneously working to reroute the pipeline around these problematic areas.

In the Straits of Mackinac, that means attempting to put Line 5 in a tunnel underneath Lake Michigan. This requires federal permits – which will likely be issued soon – as well as state permits. The permission issued by the Michigan Public Service Commission to build the tunnel is being challenged in the Michigan Supreme Court, while advocates are pressuring Whitmer not to issue another state permit that is also required.

The situation is similar in Wisconsin, where federal permits for rerouting the pipeline outside the reservation – but not beyond the watershed serving the Bad River Band’s land – were issued in October 2025 by the Trump administration. The state permit is caught up in legal and political challenges.

In each case, the immediate issue is about the direct environmental impacts of the projects. But also in each case, the underlying battle is about the long-term effects of projects involving fossil fuels. Environmental advocates want the state and federal agencies to consider the permits in light of the potential for more climatic, health and environmental damage from burning the oil the pipeline carries. Enbridge and its allies want to focus narrowly on local ecological impacts and not on the larger debate about the future of fossil fuels.

The bigger debate

As the highest court in the land considers what some might see as a very mundane and localized issue, I believe it’s useful to peel back the layers and see deeper meaning. Jeffrey Insko, an American studies professor at Oakland University and tireless chronicler and analyst of the Line 5 saga, summarizes this depth well:

“If shutting down Line 5 were about nothing more than getting an aging pipeline out of the water, if it weren’t about addressing the climate crisis, about reducing fossil fuel consumption, about a habitable future, about cultivating better relations with the more-than-human world, about respecting Indigenous rights and lifeways, it wouldn’t be a movement worth having. It would just be a technical problem with a technical solution, one that basically accepts the way things are. But shutting down Line 5 is ultimately a step toward changing the way things are.”

The Supreme Court’s ruling may be on technical grounds, but its repercussions could be very wide indeed.

Artists and writers are often hesitant to disclose they’ve collaborated with AI – and those fears may be justified

Source: The Conversation – USA (2) – By Joel Carnevale, Assistant Professor of Management, Florida International University

In a recent survey of more than 2,500 creative professionals, 83% reported using AI in their work. EuroChild/iStock via Getty Images

Generative artificial intelligence has become a routine part of creative work.

Novelists are using it to develop plots. Musicians are experimenting with AI-generated sounds. Filmmakers are incorporating it into their editing process. And when the software company Adobe surveyed more than 2,500 creative professionals across four continents in 2024, it found that roughly 83% reported using AI in their work, with 69% saying it helped them express their creativity more effectively.

The appeal is understandable. Emerging research shows that generative AI can support the creative process and, at times, produce outputs that people prefer to work made by humans alone.

Yet there’s an important caveat that my colleagues and I have recently begun to explore in our research: Positive views of creative work often shift once people learn that AI was involved.

Because generative AI can produce original content with minimal human input, its use raises questions about quality, authorship and authenticity. Especially for creative work closely tied to personal expression and intent, AI involvement can complicate how audiences interpret the final product.

Organizational behavior researchers Anand Benegal, Lynne Vincent and I study how people establish, maintain and defend their reputations, particularly in creative fields.

We wanted to know whether using AI carries a reputational cost – and whether established artists are shielded from the backlash.

No one is immune

When we set out to examine these questions, two competing possibilities emerged.

On one hand, individuals with strong reputations are often granted greater latitude. Their actions are interpreted more favorably and their intentions given the benefit of the doubt. So established artists who use novel technologies like AI may be seen as innovative or forward-thinking, while novices are viewed as dependent or incompetent.

On the other hand, established creators may be held to higher standards. Because their reputations are closely tied to originality and personal expression, AI use can appear inconsistent with that image, inviting greater scrutiny rather than leniency.

To test these competing possibilities, we conducted an experiment in which participants listened to the same short musical composition, which was described as part of an upcoming video game soundtrack.

For the purposes of the experiment, we misled some of the participants by telling them that the piece had been written by Academy Award–winning film composer Hans Zimmer. We told others that it had been created by a first-year college music student.

Across the experimental conditions, some participants were informed that the work was created “in collaboration with AI technology,” while others received no such information. We then measured changes in participants’ perceptions of the creator’s reputation, perceptions of the creator’s competence and how much credit they attributed to the creator versus the AI.

Our results showed that the creator’s existing reputation did not protect them: Both Zimmer’s reputation and that of the novice took a hit when AI involvement was disclosed. For creators considering whether their past success will shield them, our study suggests this might not be the case.

Credit where credit is due?

That said, reputation was not entirely irrelevant – it did shape how evaluators interpreted the creator’s role in the work.

The preexisting reputations of established creators did provide a limited advantage. When we asked participants to indicate how much of the work they attributed to the human creator versus the AI, evaluators were more likely to assume Zimmer had relied less on AI.

In other words, an artist’s prior reputation shaped how people judged authorship, even if it didn’t shield them from reputational damage.

This distinction points to an important implication. The backlash may not stem simply from the presence of AI but from how observers interpret the balance between human contribution and AI assistance.

At what point does collaborating with AI begin to be perceived less like assistance and more like handing over control of the creative process? In other words, when does AI’s role become substantial enough that it is seen as the primary author of the final product?

For instance, a composer might use AI to clean up background noise, adjust timing or suggest alternative harmonies – decisions that refine but do not fundamentally alter their original work. Alternatively, the composer might ask AI to generate multiple melodies, select one they like and make minor adjustments to tempo or instrumentation.

Our study did not vary the degree of AI involvement; participants were told only that AI was used or not mentioned at all.

But the findings suggest that how much AI is used – and how central it appears to the creative process – matters. For creators and organizations, the question may not be whether AI is involved but whether audiences are made aware of the extent of its involvement.

To disclose or not to disclose?

A practical question that naturally follows is whether creators should disclose their AI use.

The New York Times recently reported that some romance novelists were quietly incorporating AI tools into their writing process without disclosing it to readers. This reluctance appears to be widespread: A 2025 workplace survey found that nearly half of employees conceal their use of AI tools, often out of concern that others will view them as cutting corners or question their competence.

Is silence strategically wiser than transparency?

In our first experiment, the composer’s work either mentioned AI collaboration or didn’t mention AI at all.

But we went on to conduct a second experiment to examine disclosure more directly. This time, participants evaluated an employee at an advertising agency.

Everyone first learned that this employee had a strong reputation for creativity. Then, depending on the version of the scenario they saw, the employee either openly said they used AI to help with their creative work; said they used AI only for administrative tasks, such as scheduling meetings; explicitly said they avoided using AI because creativity should come from one’s own thoughts and experiences; or said nothing about AI at all.

This allowed us to see how both using AI and how that use was disclosed influenced judgments of the employee’s creativity and reputation.

The results were clear in one respect: Disclosing AI use harmed the employee’s reputation.

Just as importantly, explicitly stating that AI was not used did not improve evaluations. In other words, there was no reputational advantage to publicly distancing oneself from AI. Staying silent led to evaluations that were at least as favorable as explicitly saying no AI was used.

Our findings suggest that disclosure decisions are asymmetric. For creators who use AI, transparency carries costs. For those who abstain, making clear that they didn’t use AI doesn’t confer an advantage over remaining silent.

Debates over disclosure of AI use in creative fields will continue to be hotly debated. But from a reputational standpoint – at least for now – our findings suggest that disclosing AI use carries costs.

Florida’s proposed cuts to AIDS drug program threaten patient care and public health

More than 128,000 Floridians are living with HIV. The state has the second-highest rate of new HIV diagnoses after Georgia, with approximately 4,500 new diagnoses in 2023, the most recent year for which data is available.

But access to treatment could be in jeopardy if potential budget cuts, announced in January 2026 by the Florida Department of Health, are enacted.

These changes, set to go into effect on March 1, would cut funding for the state’s AIDS Drug Assistance Program, which helps more than 31,000 Floridians with HIV/AIDS afford care.

I am an emeritus professor of medicine and a practicing clinician in the Tallahassee area who specializes in HIV/AIDS treatment. Many of my patients have been treated through this state program over the past 17 years, so I am deeply concerned about threats to its funding.

Funding access to care

Since its creation in 1996, the Florida AIDS Drug Assistance Program has been funded through the Ryan White CARE Act, which Congress passed into law in 1990. The law ensures people with HIV have access to clinical care, housing support, nutrition, case management, and behavioral and substance use care. Most importantly, it guarantees access to medications to treat HIV and its complications.

More than half of those served by the Florida AIDS Drug Assistance Program earn less than US$22,024 per year, which is 138% of the federal poverty level. While researchers can’t say exactly how many lives have been saved by this program, modeling studies have determined that AIDS drug assistance programs across the U.S. are cost-effective.

But the Florida Department of Health says that it is facing a $120 million budget shortfall, and that the federal Ryan White funds are no longer enough to keep the program going without major cuts to services.

Loss of care and insurance

Currently, the program provides access to medication for low-income, HIV-positive Floridians either by directly giving them prescription medications or by paying for insurance coverage for them that includes HIV medications.

The proposed cuts would stiffen the eligibility requirement for the program from earning 400% of the federal poverty level or below, about $88,000 per year, down to 130% or below, about $21,000 per year. This would immediately remove financial support used by about 16,000 patients to access lifesaving medications.

The cuts would also stop program funds from being used to purchase health insurance for eligible patients. The Department of Health has also proposed changing which drugs the program can cover, removing the recommended and most commonly prescribed drug for treating HIV, Biktarvy.

Without access to insurance coverage and medication, these patients face worse health outcomes, and HIV transmission is likely to increase. Ultimately, this would lead to higher health care costs in Florida and more deaths from HIV/AIDS.

Pushing back

AIDS Healthcare Foundation, a national HIV advocacy and provider network, is suing the Florida Department of Health to require that it go through the normal rulemaking process to make changes to the program. Florida statute requires that substantive changes to a program undergo a process of public announcement, followed by a public comment period, before the change is enacted, which did not happen in this case.

An administrative judge has approved an expedited hearing for the lawsuit and will issue a ruling before March 1.

The foundation has also filed a second suit to determine the cause of the Department of Health’s $120 million budget shortfall.

Meanwhile, in the state legislature, both the Florida Senate and House have attempted to include additional funding for the program in their respective budget proposals. But the final budget won’t be voted on until later this March, and Gov. Ron DeSantis has line-item veto authority.

For now, I, along with other health care providers, am scrambling to ensure that patients do not lose access to their medications. We worry that if the drug assistance program is cut, Florida could see a return to the days of increasing HIV-related complications, hospitalizations and deaths.

Why standing in solidarity with immigrants is an act of accompaniment in Catholic philosophy

In Portland, Oregon, people wearing inflatable frog costumes – The Portland Frog Brigade – danced outside immigration offices. In Chicago, parents and neighbors walked children to and from school, forming “magic schoolbuses” for families who feared detention.

Thousands of Americans have taken to the streets since fall 2025 to protest against U.S. Immigration and Customs Enforcement’s tactics. These public demonstrations include the more familiar-looking protest signs and chanting, as well as other everyday ways of showing solidarity with minority groups being targeted.

The Americans taking part come from many different faith traditions, and none. But this type of solidarity reminds me of “accompaniment,” a concept I study as a scholar of American Catholicism and Roman Catholicism more broadly.

The idea of accompaniment is rooted in modern Catholic social thought. It was first coined by the late Pope Francis in his 2013 Apostolic Exhortation “Evangelii Gaudium,” or “Joy of the Gospel.”

Accompaniment and its history

Apostolic exhortations are letters written by popes that urge Catholics and non-Catholics alike to demonstrate their faith in everyday actions such as caring for neighbors, the poor and the dispossessed. They also respond to specific issues and challenges of the particular time, such as famine, war and poverty.

Francis penned his call to action soon after he became the pope in the midst of escalating global humanitarian and refugee crises – notably, the death of thousands of migrants crossing the Mediterranean to the island of Lampedusa, near Sicily, in June 2013.

Francis demanded that Catholics and the broader global community pay attention to the dignity and humanity of migrants and called for a reawakening of people’s consciences “so that what happened would not be repeated.” Francis called the apathy to the death of migrants “globalization of indifference” to suffering.

He urged Catholics around the world to show love and mercy for the most vulnerable people in demonstrable ways. Calling it the “art of accompaniment,” he used the imagery of walking alongside the poor and taking off sandals in a sign of solidarity.

As the first pope from Latin America, Francis’ teachings on accompaniment were rooted in the Catholic liberation theology that spread throughout the region in the late 1960s and 1970s.

Liberation theology embraces putting the needs of the most vulnerable first and is grounded in biblical teachings. It prioritizes a “preferential option for the poor.”

Francis stands within a long tradition of Catholic social teaching that can be traced back to Pope Leo XIII. Leo was the first modern pope to coin the term “social doctrine,” an official Catholic teaching on how to build and maintain just and equitable economies.

Leo issued the papal document “Rerum Novarum” – “On Capital and Labor” – in May 1891 in the midst of the Industrial Revolution. Rerum Novarum emphasized the dignity of work and called for fair wages and humane working conditions.

The Catholic Church today and immigration

In more recent times, Pope Leo XIV – like his predecessor Francis and the earlier pope whose name he chose – has embraced a preferential option for the poor and an ethic of accompaniment. On Oct. 9, 2025, he issued his first exhortation, “Dilexi Te” – “I Have Loved You” – continuing Francis’ and the modern church’s focus on caring for vulnerable people.

In a section dedicated to migrants, he wrote that humans will be judged by how well they treat people who are poor, sick, imprisoned and foreign. Demonstrating love and concern for the poor, Leo emphasized, was a “hallmark of faith.”

Leo also endorsed a Nov. 12 pastoral message from the U.S. Catholic Council of Bishops urging immigration reforms that “recognize the fundamental dignity of all persons,” while maintaining national security interests, as both were possible. He urged Catholics and other “people of goodwill” to “listen carefully” to this message.

Accompaniment and people of goodwill

Accompaniment is uniquely Catholic, but the social thought it describes goes far beyond any religious denomination. From Los Angeles to Washington, D.C., everyday Catholics and non-Catholics alike have been demonstrating solidarity with the immigrants.

They are rejecting ICE’s aggressive tactics while demonstrating that they value human dignity and human rights.

Accompaniment appears to be a common language of solidarity – a way for “people of goodwill,” as Leo put it – to stand in solidarity with the most vulnerable people and refuse to accept immigration policies they see as being dehumanizing.

Baptists have helped shape debate about religious freedom for over 400 years – up to today’s 10 Commandments laws

Louisiana can proceed with a law requiring public schools to display the Ten Commandments, according to a federal court decision on Feb. 20, 2026. The U.S. Fifth Circuit Court of Appeals voted that it is too early to determine whether the requirement violates the First Amendment of the Constitution, which protects religious liberty and prohibits the government from establishing religion. The judges heard arguments in Louisiana’s law and a similar Texas one in January 2025 but have yet to rule on the latter.

One of the plaintiffs in a lawsuit filed against the Texas law is Rev. Griff Martin, a Baptist pastor. Martin has criticized the Ten Commandments mandate as not just a violation of American precepts but religious ones as well. In a press release by the American Civil Liberties Union of Texas, which is representing the plaintiffs, he stated that “the separation of church and state (is) a bedrock principle of my family’s Baptist heritage.”

Speaker of the House Mike Johnson, who represents Louisiana, is also the country’s most prominent Baptist politician – and perceives the matter differently. The Louisiana law is not an effort to establish religion, but to acknowledge the country’s “history and tradition,” he told reporters in 2024.

Baptists have long advocated for religious freedom. But as a scholar of Baptist theology and history, I know that this record is far from simple. In fact, both Martin and Johnson have ample precedent for their opinions on Baptist identity and the relationship between church and state.

Historians and political scientists often divide interpretations of the First Amendment into two broad categories: “separationism” and “accommodationism.” According to separationists, government and religion should have no formal relationship. Accommodationists, on the other hand, believe government depends on and should encourage religion in general – or Christianity, specifically.

An honest look at their history reveals that Baptists have taken various stances in this debate, reflecting their overall diversity.

Call for separation

The phrase “separation of church and state” is famously traced back to an exchange between Thomas Jefferson and a group of Baptists.

After Jefferson’s election as president in 1800, the Danbury Baptist Association in Connecticut wrote a letter of congratulations. Jefferson responded, celebrating their shared beliefs in religious liberty. He cited the First Amendment, which says that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.” In Jefferson’s interpretation, religion is a matter between individuals and God, and so these clauses rightly erected a wall that defended conscience from the government.

But the image of a barrier between church and state is older than Jefferson’s letter. It first appears in the writing of Roger Williams, a radical preacher who founded Rhode Island in 1636. This was the first American colony to grant religious freedom for all people. Williams also helped organize America’s first Baptist church. In one of his works, Williams explained that the “hedge or wall of Separation” protected the “Garden of the Church” from the world.

Baptist separationism goes back to the beginning of the movement. The first Baptists were a group of English exiles living in Amsterdam in 1609. The church split, and part of the community returned to Britain under the leadership of Thomas Helwys.

In 1612, Helwys boldly delivered a book to King James called “A Short Declaration of the Mystery of Iniquity.” In it, he offered the first defense of absolute religious liberty in the English language.

Helwys declared the king was mortal and not God. Therefore, a ruler “hath no power over the mortal soul of his subjects” in matters of religion. He argued for tolerance not just of different Christian sects but other religions and nonbelievers: “Let them be heretics, Turks, Jews, or whatsoever, it appertains not to the earthly power to punish them in the least measure.”

King James had Helwys thrown in prison for his impudence, where he eventually died.

Baptists who argue for strict separation of church and state have done so for several reasons. They believe that the conscience of each individual must be respected. They contend that government is not competent to judge between true and false religion. And they fear that an alliance with state power corrupts the church’s witness to the gospel.

Seeking accommodation

As much as contemporary Baptists quote Helwys, his work was forgotten for many years following his death. In the American Colonies, many people saw Williams’ Rhode Island colony as a land of dangerous anarchy.

Baptists faced legal obstacles and sometimes violent persecution in colonies with established churches, such as Massachusetts and Virginia. They became fierce advocates for religious liberty during the American Revolution and the framing of the Constitution. But even as they believed in liberty for individuals and churches, many Baptists also believed government should support Christian faith and morals.

A significant figure who illustrates accommodation was Isaac Backus, a Massachusetts pastor. Backus fervently opposed taxation to benefit the Congregationalist Church in some New England colonies. But he also felt that the state should reflect shared religious tenets. As a result, he endorsed various morality laws, religious tests for office and the government printing of Bibles.

Baptists who support accommodation – the idea that government should cooperate with religion – tend to see the United States as a Christian nation, not simply a nation with Christian citizens. Today, 63% of Americans identify as Christian.

Second, they argue that successful governance relies on the population being virtuous, and that the best guarantee of virtue is practicing Christianity.

Religious faith as a prerequisite for civic stability was a common belief in early America. George Washington expressed this view in his farewell address.

Johnson advocates a similar perspective today. In a 2022 lecture at Louisiana Christian University, the Baptist college that formerly employed him, Johnson asserted that God lies at America’s foundations, and decline has occurred because biblical morality has been abandoned. He has also declared in a social media post that “just government” depends on the fear of “eternal judgment.”

Divided by faith

Are you a good Baptist if you oppose government-mandated displays of the Ten Commandments? Or are you a good Baptist if you support them? From a historical perspective, the answer to both questions is yes.

Religious liberty and church-state separation remain contested concepts not just politically but theologically. Some Baptists support a neutral government and the full equality of religious minorities. At the other end of the spectrum, a few explicitly embrace Christian nationalism.

The historian Barry Hankins proposed that Baptists’ opinions on church and state depend on their perceptions of culture. Separationists see themselves comfortably finding their place in a pluralistic society. Accommodationists, meanwhile, worry that a secularized country will curtail the free exercise of religion.

On this issue, and many others, I believe Baptists will long remain a people divided by their shared faith.

CAN 2025 : les clés pour comprendre les controverses arbitrales et restaurer la confiance

Source: The Conversation – in French – By Pierrick Desfontaine, Enseignant et agrégé d’Education Physique et Sportive, Université de Toulon

La dernière Coupe d’Afrique des nations (CAN) organisée au Maroc restera dans les mémoires non seulement pour l’intensité sportive et l’engouement populaire qu’elle a suscités, mais aussi pour les controverses arbitrales. Des actions litigieuses, l’usage de l’assistance vidéo à l’arbitrage (VAR) et la diffusion massive de ralentis ont ravivé les soupçons de favoritisme. Cela pose la question de la confiance dans l’arbitrage africain à l’ère du numérique.

The Conversation Africa a interrogé Pierrick Desfontaine, spécialiste des enjeux sociotechniques dans l’arbitrage des sports collectifs. Il a mené des études sur la VAR et les arbitres d’élite qui l’utilisent en France, et a enquêté au plus près d’eux à Clairefontaine. Universitaire attaché au rôle d’entraîneur-éducateur et à une direction du jeu humaine, il propose ici des pistes pour améliorer l’arbitrage africain..

Pourquoi l’arbitrage a-t-il suscité autant de controverses lors de la dernière CAN ?

L’arbitrage n’a pas suscité plus ou moins de controverses que lors de toutes les compétitions de renom depuis que l’assistance vidéo à l’arbitrage (VAR) est installée. Les polémiques autour de l’arbitrage sont inhérentes aux émotions du football (amplifiées par les médias, les réseaux sociaux) et aux attitudes souvent impétueuses de ses acteurs. Elles sont renforcées par l’illusion que les technologies vont les régler : la non-résolution de ces erreurs d’arbitrage (parfois insolubles, même avec toutes les images possibles) renforce l’incompréhension des passionnés d’un sport total, mondial et excessif.

Ensuite, lorsque le pays organisateur est favori, les suspicions de favoritisme de l’arbitrage ou de corruption dans l’organisation émergent. Le Maroc, qui recevra une partie du Mondial 2030, a démontré des capacités sécuritaires et organisationnelles certaines. D’inévitables accrocs interviennent lorsqu’on coordonne de tels tournois. Cela est d’autant plus dommageable lorsque l’autre pays finaliste, le Sénégal, en est victime.

Rappelons pour finir que la CAN est le troisième tournoi international de football le plus suivi. Avec la progression du Maroc (demi-finaliste de la Coupe du monde en 2022, champion du monde U20), l’engouement sur le continent et dans les diasporas est considérable. Le niveau augmente sur le terrain, les staffs s’étoffent, des entraîneurs locaux émergent et l’arbitrage doit suivre ce rythme.

Les arbitres ont bénéficié d’un niveau d’assistance technologique important. De quels outils s’agit-il exactement ?

Comme dans toutes les compétitions internationales, un faisceau d’outils était déployé sur chaque match, dispositif dont l’arbitre central est la clef de voûte. Ce dernier est équipé d’oreillettes le reliant à ses assistants et aux assistants vidéo situés dans une régie. Le protocole de la VAR peut être déclenché par ces derniers, dans quatre cas. Ce sont donc des acteurs littéralement hors jeu qui appellent le central pour qu’il aille consulter un poste vidéo situé en bordure de terrain (et dont la sécurité et le confort de lecture n’ont pas été satisfaisants lors de la finale notamment).

De plus, l’arbitre central a une montre qui vibre lorsque le ballon a entièrement franchi la ligne. C’est la technologie sur la ligne de but (GLT). Cette dernière est binaire, relativement fiable et compréhensible. En revanche, la complexité de l’arbitrage est exacerbée lors des protocoles VAR : ralentis, zooms, multiples visionnages viennent apporter une profusion de points de vue qui peut virer à la confusion. L’arbitre central de la finale de la CAN 2025, Jean-Jacques Ndala Ngambo, est confirmé, mais aucune expérience ne peut préparer au chaos qui a entouré le terrain.

Dans quelle mesure les ralentis télévisés, les réseaux sociaux et les commentaires en ligne influencent-ils la perception du public vis-à-vis des décisions arbitrales ?

Concernant la télévision,, elle est en partie impliquée dans la genèse de la VAR. La remise en question dépréciative de la fiabilité arbitrale occupe depuis les années 1980 des programmes télévisuels qui décryptent les actions litigieuses. Les réseaux sociaux rajoutent aujourd’hui une instantanéité dans l’utilisation parfois manipulatrice des images et des informations. L’utilisation de la VAR interroge la possibilité de concilier l’activité arbitrale, interprétative, subjective et basée sur les aléas, avec les promesses d’objectivité et de rationalité du numérique augmenté.

CAN 2025 de football : les réussites et les ratés de l’édition marocaine


Cette question sur le public est l’occasion de mettre en avant les réflexions du sociologue du sport Julien Puech qui a vécu la CAN avec la population de Rabat. Il affirme que la perception de l’héritage de cette compétition n’aura de sens que si ses investissements en termes d’installations, de formation, d’arbitrage profitent à un large échantillon de Marocains et de Marocaines adeptes des football(s).

Julien Puech a pu observer un engouement, de nombreuses scènes d’échange. La veille des matchs, une foule cosmopolite se rendait à la Médina pour partager une ambiance festive. Les supporters s’amusaient des situations d’arbitrage ubuesques dans des vidéos partagées sur les réseaux sociaux. On peut supposer que ces flux informationnels répondent à une fonction essentielle de l’évènement sportif : prolonger le spectacle et nourrir les débats.

Plus encore, certains voient dans ces échanges continentaux une forme de «panafricanisme». Cette pensée a été envisagée par le militant anti-colonial martiniquais Frantz Fanon comme une solidarité entre les Africains et les personnes d’ascendance africaine pour lutter en faveur de l’indépendance du continent. Encore faut il, selon Fanon, que ces interactions ne soient pas entachées de nouveaux impérialismes.

Quelles réformes ou évolutions seraient nécessaires pour restaurer la confiance dans l’arbitrage lors des prochaines éditions de la CAN ?

Certes, l’arbitrage africain doit s’améliorer. Cela passe par de l’investissement humain, matériel et économique de la part de la CAF et de la FIFA, au service de la formation initiale et continue des officiels du continent. Mais les entraîneurs, joueurs et médias ont de larges progrès à faire dans la connaissance des règles et dans l’acceptation des décisions.

Le bon entraîneur doit toujours rester un éducateur. Il ne peut pas passer outre certains principes et se mettre à invectiver l’arbitre. Il y a des acteurs cruciaux comme le coach, le capitaine, le président qui doivent être irréprochables. Des fondamentaux devraient être recadrés : obliger les joueurs à serrer la main du corps arbitral, sanctionner plus durement les dérives physiques et verbales des dirigeants, promouvoir les comportements vertueux.

La noble attitude de Sadio Mané en finale montre bien que la voie du fair play peut cadrer un match à enjeux et que les grands joueurs africains peuvent se comporter avec une éthique exemplaire.

Du côté des évolutions arbitrales, plutôt que d’investir des sommes colossales dans des technologies, il faudrait utiliser le carton blanc à tous les niveaux (10 minutes d’expulsion en cas de comportement anti-sportif) et faire reculer de 10 mètres l’emplacement d’un coup de pied arrêté en cas de contestations.

Il s’agit de s’inspirer de sports qui innovent comme le rugby, exemplaire sur le respect des hommes en noir, ou le futsal pour le co-arbitrage. Si la CAF se débarrasse de certains problèmes endémiques, pourrait se démarquer en pérennisant ces règles dans ses compétitions, en misant sur les dimensions humaines dans l’arbitrage et devenir un leader mondial sur le sujet.

Quels aspects de ces outils numériques ont bien fonctionné, selon vous, et lesquels ont montré leurs limites ?

J’ai insisté sur l’arbitrage et vous aurez compris que mes engagements d’enseignant et de chercheur, ainsi que l’analyse de presque dix saisons avec la VAR, m’ont conforté dans l’idée que ce sport aurait du se passer de ce gadget aliénant. Un football du droit à l’erreur, non coupé par de pénibles protocoles VAR, aurait pu être sanctuarisé. Je redoute la surenchère d’outils numériques (IA, robot, etc.) à moyen terme;

Prochainement, il y a la crainte que le Mondial américain de cet été ouvre la porte à des interruptions publicitaires, sous prétexte d’assistance vidéo. Par contre, les outils numériques renforçant la coordination des arbitres (oreillettes, drapeau BIP) sont à garder et à améliorer.

Il y a d’autres usages du numérique, davantage tournés vers la performance. Mon collègue Olivier Cavailles travaille depuis de nombreuses saisons en tant qu’entraîneur adjoint de Patrice Beaumelle (Maroc Espoir, Côte d’Ivoire, Mouloudia d’Alger, Angola). Il est chargé de l’analyse du jeu par la vidéo.

Présent sur cette CAN, Oliver Cavailles, dont le diplôme universitaire d’analyse de la performance est pionnier, m’a confirmé que le Maroc avait assuré des conditions de travail optimales (hardware et software) pour les analystes.

Les buts décisifs sur coups de pied arrêtés du Maroc ont montré le travail spécifique effectué, articulant vidéo et terrain, et ont donné tout son sens à cette néo-profession.

Tournés vers le progrès, les clubs et sélections du continent peuvent offrir ces nouvelles perspectives professionnelles (analyste vidéo, data scientist, sport scientist) à une jeunesse africaine entreprenante.

La selección: esperando un eclipse me quedaré

“Esperando un eclipse me quedaré, persiguiendo un enigma al compás de las olas…”. Eran los años 80, la Movida madrileña. Radio Futura cantaba en “La estatua del Jardín Botánico” algo que no llegaba nunca.

La península ibérica no ha experimentado un eclipse total de Sol desde principios del siglo XX. Pero ahora sí, se aproxima a nuestro cielo el primero de una tríada que dará a la oscuridad total poco más de un minuto de gloria. El próximo 12 de agosto un eclipse total de Sol cruzará el Ártico, Groenlandia, Islandia y atravesará la península ibérica de oeste a este al atardecer.

No es algo nuevo en el mundo. Los apagones cósmicos se suceden desde que un protoplaneta colosal del tamaño de Marte, Theia, chocó con una Tierra primitiva, blandita de magma, y se desprendió un pedazo que formó la Luna, hace al menos 4 460 millones de años… Millones de eclipses que se producen por una feliz coincidencia geométrica: el Sol es aproximadamente 400 veces más grande en diámetro que la Luna, pero también se encuentra unas 400 veces más lejos de nosotros.

Si viviéramos en Trisolaris, el planeta de la serie El problema de los tres cuerpos, serían impredecibles. En un mundo con tres soles determinar el movimiento de tres cuerpos sometidos a gravedad mutua resulta de una complejidad matemática aún hoy sin solución.

La historia asume, con sus dudas, que fue Tales de Mileto quien predijo un eclipse por primera vez, el del 28 de mayo del 585 a. e. c. Así fue como la ciencia arrebató a mitos y dioses el poder de sembrar las sombras.

Predecirlos no es lo único que vincula ciencia y eclipses. En el de 1868, desde la India, el astrónomo francés Pierre Janssen descubrió el helio, ese gas que nos pone voz de pitufos si lo inhalamos y es nutriente de las estrellas. Y los eclipses aún hoy permiten estudiar la corona del Sol cuando escapa por los bordes como el aro de fuego que saltaban los leones de los circos.

Pero hay un eclipse que aún se cuenta como el más significativo de la historia de la ciencia. Me refiero al que tuvo lugar en mayo de 1919. Dos astrofísicos decidieron entonces demostrar que la curvatura de la luz que Albert Einstein describía era algo más que una ecuación matemática. El británico Arthur Eddington viajó a la isla del Príncipe, en la costa de Turquía, y Andrew Crommelin a Sobral, en Brasil. El objetivo era fotografiar las estrellas del cúmulo de las Híades, visibles cerca del Sol en el momento del eclipse. Y así es: su posición aparente se desplaza afectada por el campo gravitatorio solar, el peso del Sol en el tejido del espacio-tiempo.

Dicen que aquel eclipse hizo mundialmente famoso a Einstein. También, que los resultados no fueron tan precisos como exige la ciencia contemporánea. Pero a Eddington le interesaba comprobar la teoría de un científico alemán y judío justo después de la I Guerra Mundial, un gesto que reconciliase al Reino Unido con Alemania. Geopolítica de principios de siglo.

Así, al fin se aproxima un eclipse total de Sol a la península ibérica. Elijan su jardín para la oscuridad.

Agroecology: rethinking global policy efficiency and funding priorities to overcome the blind spot in climate action

Source: The Conversation – France – By Fabio G. Santeramo, Associate Professor, Università di Foggia

Amid mounting concerns surrounding climate mitigation in the agriculture and forestry sectors, science-based evidence suggests a need for more effective, fair and coherent policy frameworks for cutting greenhouse gas emissions in the European Union and further afield.

International policies to protect the environment are at a crossroads: bold targets coexist with fragmented priorities, threatening the agenda. The debate is often dominated by the least effective measures, while high-impact solutions struggle to gain space and resources. Funding streams show only a faint prioritisation of green objectives, eroding the consistency of environmental action. These dynamics become especially evident in sectors where emissions are high and policies are numerous, yet strategic alignment and assessment remain scarce.

The Agriculture, Forestry and Other Land Use (AFOLU) sector, responsible for over 20% of global emissions, continues to fall through the cracks of climate policy. In the European Union, it is often described as “the missing piece in climate policy.” Yet, it continues to be regulated with several national and local initiatives, while suffering from weak coordination at the macro level (e.g. EU, multilateral agreements).

Calls for policy efficiency and multilateral climate governance

Despite a wide range of local and national initiatives targeting emissions reductions in the AFOLU sector, there remains a striking lack of assessment studies evaluating their real-world effectiveness.

Ex-post analyses, though far fewer in number, provide evidence-based insights that are key to refining future strategies. Many initiatives prioritise conventional agricultural goals (i.e income growth, yield improvement) over environmental ones. A recent OECD review on policy effectiveness, echoed by university researchers, warns of incoherence in political agendas when it comes to lowering emissions. The findings highlight differences in the performance of policy tools, raising the question: Are the most effective instruments being prioritised and funded within current policy agendas?

Russia’s invasion of Ukraine has triggered one of the largest increases in conflict-related food insecurity. The United Nations’ Food and Agriculture Organization (FAO) warns that, due to the war, millions of people could still be chronically undernourished by 2030. The crisis has pushed food security to the top of the political agenda, with the need to ensure food supply often putting environmental and climate priorities in the background.

On June 20 2025, the European Commission withdrew its Green Claims Directive, a planned crackdown on misleading environmental claims. In the EU Parliament, the move sparked strong criticism from Socialists and Liberals and marked a setback in the fight against greenwashing.

Ahead of COP30, the UN’s annual meeting for climate cooperation, held in the Amazonian city of Belém in November 2025, Brazil’s National Secretary for the Environment and Climate Change, Ana Toni, raised serious concerns about the world’s “uncertain” response to the climate crisis.

One month before COP30, only one third of the nearly 200 countries had submitted plans to meet the requirements required by the 2015 Paris Agreement, while ongoing military and trade conflicts continued to divert attention and resources away from climate action.

India’s plans for one, still remain to be seen. Described as the world’s fifth largest economy and third biggest emitter of global greenhouse gases, the country was closely watched at the UN meeting.

Highest emitting economies are on the UN’s radar

COP30 absentees included China’s President Xi Jinping and US President Donald Trump. China and the US are the two biggest emitters of planet-warming gases. At the summit China came under the closest scrutiny as the world’s second-largest economy and the biggest emitter of greenhouse gases. What alarms analysts is that China approved 11.29 gigawatts (GW) of new coal-fired power plants in the first three months of 2025, already surpassing the 10.34 GW approved in the first half of 2024. Reducing coal use is essential for China to meet its targets of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060.

Meanwhile, last June, in the US, Donald Trump was already laying the groundwork to open up 58 million acres of national forest backcountry to road construction and development, rolling back protections that have been in place since 2001. In detail, the Trump administration announced plans to repeal the 2001 Roadless Rule (describing it as outdated) which had preserved the wild character of nearly one-third of the land in national forests across the United States.

These trends could ultimately be summed up in one sentence: a policy agenda whose attention toward the environment is slowly declining, despite the growing urgency of sustainability challenges.

The Environmental impact of agricultural policies: Beyond market instruments

The expectations on the debate about agriculture’s inclusion in the EU Emissions Trading System (ETS) may be exaggerated. Our research shows that similar policies (i.e. carbon taxes, emissions trading schemes, and subsidies) are barely effective and tend to reduce emissions by percentage as high as 9%.

Agriculture potentially becoming part of the ETS is a major topic in the current policy debate. However, turning this into action faces challenges. Denmark’s recent decision to introduce a carbon tax on agricultural emissions by 2030, aiming to cut emissions by up to 70%, shows the level of ambition.

Setting a price on emissions through a fair and balanced application of the polluter pays principle makes sense. It helps cleaner alternatives compete, raises money to support a fair transition, and makes polluters take financial responsibility for the damage they cause. But for a future agricultural ETS to truly work, it must be designed properly: it needs a strict emissions cap, no free pollution permits, and a fair and efficient use of the revenues.

In the current Common Agricultural Policy (CAP), the adoption of eco-scheme uptake has been poor. To make matters worse, CAP rules have been watered down, weakening several of the “good agricultural and environmental conditions” and giving EU member stateseven more flexibility in the approval process of their strategic plans. In this context, putting a price on pollution won’t change much if the rest of the system keeps supporting polluting practices. A carbon price only works if the broader framework stops rewarding emissions in the first place.

By co ntrast, non-market policies – i.e. Protected Areas (PA), Forest Management Programs (FMP), Payments for Environmental Services (PES), and Non-Tariff Measures (NTM) – often deliver better results, with stronger impacts on reducing emissions than market-based policies. PA, broadly adopted in Indonesia and Thailand, can achieve emission reductions of up to 60%, placing them among the most impactful policy instruments available. FMP and PES show encouraging results in land-use changes, such as the conversion of croplands into forests.

Research finds that FMP, widely adopted in Brazil, are the most effective in triggering substantial shifts in land use, with forest cover increasing to as much as 50%. One reason for this is that this type of policy makes it more appealing for farmers to transition: by conserving their land, they gain access to valuable resources such as timber and other ecosystem services. It’s a win-win, for the environment and for local communities.

While non-market-based policies demonstrate strong effectiveness in reducing emissions, they continue to face significant challenges. The EU Deforestation Regulation (EUDR) is an example of this. Although the EUDR was introduced as a landmark effort to curb global deforestation by ensuring that products sold in the EU are deforestation-free, it is now facing significant political pushback. Eighteen EU member states have called on the European Commission to ease the regulation, arguing that it imposes disproportionate and costly administrative burdens even on countries with negligible deforestation risk. They warn that the law, in its current form, could hurt competitiveness, drive up production costs, and disrupt supply chains; pressures that have already led to the postponement of its enforcement and risk diluting its environmental ambition before it is fully implemented.

Effective agricultural policy vs current funding priorities

If we are truly committed to climate goals, especially in the AFOLU sector, we must focus on policies that are direct, enforceable, and grounded on solid science. The research evidence illustrates that the most meaningful progress comes from mandatory rules-based approaches, such as PA.

According to the European Commission’s financial report for 2023, a total of €378.5 billion has been made available under the CAP since January 2021.

Of this, “The vast majority, around €283.9 billion, goes to direct payments and market measures through the European Agricultural Guarantee Fund (EAGF), primarily to support farmers’ incomes. Meanwhile, just €94.2 billion is allocated to rural development via the European Agricultural Fund for Rural Development (EAFRD), the branch of the CAP that funds environmental protection and biodiversity efforts, such as PA.”

In theory, the CAP aims to place environmental protection at the heart of its strategy. But when we follow the money, the picture is less balanced. Between 2021 and 2027, over €40 billion per year was directed to market-related expenditure and direct payments, while rural development, the pillar supporting green initiatives, receives less than half of that.

What’s the upshot?

Most of the funding still goes to policies that are least effective at protecting the environment, especially when it comes to cutting emissions, while the more impactful measures remain underfunded. It is a mismatch that risks undermining Europe’s climate and biodiversity ambitions.

Lissages capillaires : attention au risque d’insuffisance rénale aiguë

Source: The Conversation – France in French (3) – By Pauline Guillou, Chargée de projet scientifique, Agence nationale de sécurité sanitaire de l’alimentation, de l’environnement et du travail (Anses)

L’Agence nationale de sécurité sanitaire (Anses) a conclu, en janvier 2025, à un lien fortement probable entre la présence d’acide glyoxylique, un ingrédient utilisé dans certains produits de lissages capillaires, et la survenue de cas d’insuffisances rénales aiguës. En attendant une évaluation des risques au niveau européen, cette substance ne fait l’objet d’aucun encadrement ni restriction d’usage. Les consommateurs sont appelés à ne pas utiliser ces produits afin de limiter les risques pour leur santé.


Après plusieurs signalements de cas d’insuffisance rénale aiguë à la suite de la réalisation de lissages capillaires en France et à l’étranger, des études scientifiques ont montré qu’une substance contenue dans ces produits, l’acide glyoxylique, pouvait être à l’origine de ces effets.

Dans un avis rendu en janvier 2025, l’Agence nationale de sécurité sanitaire, de l’alimentation, de l’environnement et du travail (Anses) a confirmé un lien fortement probable entre cet ingrédient et cet effet indésirable et préconise une évaluation des risques au niveau européen.

Quelles recommandations pour la sécurité des consommateurs ?

Pour l’heure, les autorités sanitaires conseillent d’éviter d’utiliser des produits capillaires contenant de l’acide glyoxylique et d’être vigilant en cas de symptômes inhabituels après un lissage.

En attendant d’éventuelles mesures réglementaires, l’Anses émet les recommandations suivantes :

  • Ne pas utiliser de produits de lissage capillaire contenant de l’acide glyoxylique ;
  • En cas de symptômes inhabituels pendant l’application ou dans les heures suivant la réalisation d’un lissage capillaire (douleurs lombaires, fatigue, nausées…), que le produit contienne de l’acide glyoxylique ou non, il est recommandé de consulter un médecin ou de contacter un centre antipoison en indiquant la réalisation d’un lissage capillaire ;
  • Pour contacter un centre antipoison : se rendre sur le site Internet Centres-antipoison.net ou appeler le (33)1 45 42 59 59 ;
  • En cas de symptômes inhabituels pendant l’application ou dans les heures suivant la réalisation d’un lissage capillaire (douleurs lombaires, fatigue, nausées…), que le produit contienne de l’acide glyoxylique ou non, il est également recommandé de déclarer l’incident sur le portail de signalement des évènements sanitaires indésirables du ministère en charge de la santé : Signalement.social-sante.gouv.fr/

À noter que la vigilance doit être de mise pour des lissages capillaires réalisés chez le coiffeur, en salon ou à domicile, mais aussi directement par le consommateur. Les produits capillaires lissants susceptibles de contenir de l’acide glyoxylique (même si leur étiquetage ne le précise pas) sont en effet disponibles dans le commerce et peuvent être achetés directement par le grand public. Ces lissages sont parfois – mais pas systématiquement – présentés sous certaines dénominations (« lissages brésiliens », « lissages indiens », etc.).

Une première alerte auprès du dispositif de cosmétovigilance en France

En janvier 2024, l’Anses, nouvellement en charge de la cosmétovigilance en France, a reçu de la part d’un néphrologue le signalement d’un cas d’insuffisance rénale aiguë supposée en lien avec l’utilisation d’un produit de lissage capillaire. Ce signalement concernait une femme ayant connu trois épisodes d’insuffisance rénale aiguë en trois ans qui se sont déclarés systématiquement quelques heures après la réalisation d’un lissage capillaire. Le seul événement commun aux trois épisodes était en effet l’application d’un soin capillaire le jour du début des symptômes (La cosmétovigilance consiste à assurer une surveillance et, le cas échéant, à identifier des effets indésirables chez l’humain liés à des produits d’hygiène ou de beauté que l’on classe, selon la réglementation, dans la catégorie dite des « cosmétiques », ndlr.)

Lors des trois épisodes, les premiers symptômes étaient une sensation de brûlure du cuir chevelu durant toute la durée de l’application, puis l’apparition d’ulcérations du cuir chevelu. Une douleur lombaire apparaissait dans l’heure suivant le soin, suivie de nausées et d’asthénie le jour même. Les produits utilisés lors des deux premiers soins lissants n’ont pu être identifiés. Le troisième produit, lui, était connu.

Des effets indésirables graves qui suscitent l’attention

Les néphrologues ayant pris en charge cette patiente ont mené des recherches afin d’identifier l’origine de cet effet. Ils ont ainsi établi un lien de causalité entre l’insuffisance rénale aiguë et une substance contenue dans le produit utilisé lors du troisième soin, l’acide glyoxylique. Ces conclusions résultent, d’une part, de l’observation de la toxicité rénale de l’acide glyoxylique chez la souris et, d’autre part, de l’existence de cas humains similaires identifiés dans plusieurs pays, notamment en Israël.

L’acide glyoxylique est utilisé dans les produits de lissage capillaire en remplacement du formaldéhyde. Le formaldéhyde était utilisé dans les produits cosmétiques et notamment pour les lissages capillaires, mais a été interdit en 2019 du fait de son classement comme substance cancérogène en 2014 dans le cadre du règlement européen CLP. L’industrie a alors développé des alternatives, dont l’acide glyoxylique.

Au regard de ces éléments, l’Anses s’est autosaisie pour dresser un état des lieux des connaissances sur la toxicité rénale de l’acide glyoxylique présent dans les produits lissants et déterminer si un encadrement des conditions d’utilisation de cette substance était nécessaire.

En août 2024, deux nouveaux signalements d’insuffisance rénale aiguë chez des personnes s’étant fait lisser les cheveux ont été adressés à l’Anses. Ces signalements concernaient des femmes, ayant présenté des symptômes tels que des maux de tête, des douleurs lombaires, des nausées, de la fatigue, ou encore une soif excessive dans les heures suivant le soin. Leurs analyses de sang ont mis en évidence une augmentation significative des taux de créatinine, un marqueur biologique de l’insuffisance rénale. Aucune autre cause explicative n’a pu être identifiée. L’évolution de leur état de santé a été favorable, après une hydratation, voire une hospitalisation de plusieurs jours pour l’une d’elles.

Appliqué sur le cuir chevelu, l’acide glyoxylique peut pénétrer dans l’organisme

L’analyse de la littérature scientifique menée par l’Anses a permis d’identifier des données à la fois expérimentales et cliniques établissant un lien entre l’utilisation de produits lissants pouvant contenir de l’acide glyoxylique et la survenue d’une insuffisance rénale aiguë dans les heures qui suivent.

Concernant les 26 cas similaires survenus entre 2019 et 2022 en Israël, pour certains d’entre eux, des biopsies rénales ont révélé la présence des dépôts de cristaux d’oxalate de calcium. Ces derniers peuvent constituer des calculs rénaux qui altèrent le fonctionnement des reins de façon parfois sévère. Parmi ces 26 cas, 11 patientes ont été exposées à des produits de lissage à base de kératine affichant, dans leur composition, des « dérivés de l’acide glycolique ». Pour les autres, le type de produit lissant n’a pas été identifié.

À également été recensé en Suisse, et présenté dans une publication datant de 2024, le cas d’une femme d’une quarantaine d’années ayant développé une insuffisance rénale aiguë après un lissage des cheveux. La biopsie rénale avait également montré des dépôts de cristaux d’oxalate de calcium. La composition du produit utilisé reste cependant inconnue.

Par ailleurs, des tests expérimentaux menés sur des rongeurs ont confirmé le rôle néphrotoxique de l’acide glyoxylique lors d’une exposition par voie cutanée. Enfin, la formation de cristaux d’oxalate dans l’organisme à partir de l’acide glyoxylique a également été démontrée.

L’ensemble de ces données suggèrent donc que l’acide glyoxylique, lorsqu’il est appliqué sur le cuir chevelu, peut pénétrer dans l’organisme et se transformer en oxalate de calcium.

Une substance dont l’utilisation n’est ni encadrée ni limitée

À la suite de l’analyse de l’ensemble des données existantes, l’Anses a donc publié en janvier 2025 un avis qui conclut au rôle causal fortement probable de l’acide glyoxylique dans la survenue d’insuffisances rénales aiguës observées après l’application de produits lissants.

À ce jour, cette substance ne fait cependant pas l’objet de dispositions spécifiques dans le cadre du règlement cosmétique (en particulier selon les annexes II et III, qui correspondent respectivement aux substances interdites et aux substances faisant l’objet de restrictions). Son utilisation n’est donc ni encadrée ni limitée.

Comme l’interdiction ou la restriction d’une substance cosmétique ne peut se faire au niveau national, l’Anses recommande donc de réaliser une évaluation des risques au niveau européen afin de statuer sur la sécurité de l’utilisation de cette substance dans les produits de soins capillaires et, par voie de conséquence, sur la nécessité de telles mesures réglementaires.

De plus, l’Anses préconise qu’une attention particulière soit portée aux substances (présentes dans les produits capillaires et autres produits cosmétiques) pouvant se métaboliser en acide glyoxylique.

En mars 2025, l’Anses a présenté ses travaux devant le groupe de travail sur les cosmétiques organisé par la Commission européenne réunissant les États membres et les parties prenantes. À la suite de quoi, un appel à données a été lancé par la Commission européenne dans le but de compiler toutes les informations scientifiques disponibles afin d’évaluer la sécurité de cette substance dans les produits cosmétiques. Cet appel à données est ouvert jusqu’au 8 avril 2026.

Se mobiliser pour protéger le public en Europe et dans l’Union européenne

Il est à noter que, depuis octobre 2024, 15 nouveaux cas d’insuffisance rénale aiguë ont été signalés en France. Ces nouveaux cas ont, par ailleurs, montré que l’acide glyoxylique pouvait être présent dans les produits même si ce n’était pas mentionné sur l’étiquette.

En effet, parmi les six produits pour lesquels il n’était pas fait mention de la substance dans la composition, l’analyse de trois d’entre eux a confirmé qu’ils en contenaient. Deux nouveaux cas ont également été publiés dans la littérature scientifique en Tunisie et en Algérie.

Cet exemple démontre par ailleurs l’importance de signaler tout effet indésirable lié à ces produits et aux produits cosmétiques sur le portail de signalement des événements indésirables du ministère en charge de la santé. Ces signalements sont essentiels afin de mieux comprendre les risques et protéger les consommateurs.

3 ways Canada can navigate an increasingly erratic and belligerent United States

Source: The Conversation – Canada – By Charles Conteh, Professor of Public Policy and Administration, Department of Political Science, Brock University

The United States Supreme Court recently struck down President Donald Trump’s sweeping global tariffs imposed under the country’s International Emergency Economic Powers Act. The court stated that the law, intended for national emergencies, does not grant the government the authority to impose tariffs.

In early 2025, Trump invoked the act to impose tariffs on Canada, along with Mexico and China, claiming the countries failed to stop illicit drug trafficking into the United States.

The ruling is the latest episode in a political dust-up between Canada and its neighbour to the south which recently involved the Gordie Howe International Bridge linking Ontario and Michigan.

More than steel or stone, the bridge is a symbol of a shared destiny that both respects and transcends differences. Despite their historical, institutional and political differences, Canada and the United States have bonded economically as neighbours, generating shared prosperity over the past two centuries.

In 2023, I wrote a book chapter Canada and the United States: A Symbiotic Relationship or Complex Entanglement? In that chapter, I posed a question: What if the United States becomes more aggressive and even less open to working co-operatively with Canada? To answer that question, Canada can draw lessons from its centuries-long coexistence with an often erratic neighbour to successfully navigate the economic volatility of the present era.

While the recent Supreme Court ruling presents a setback for Trump, it is unlikely to stop him from using U.S. economic and military might as leverage against Canada and other countries. As Canada navigates this belligerent U.S. government, a lingering question is whether this history of interwoven reciprocity is deteriorating into a complex entanglement of vulnerability.

Two neighbours, different worlds

In the book chapter, I describe the Canada-U.S. relationship as a complex picture of deep interdependence, marked by significant power imbalances, and the creative ways Canada has learned to adapt and prosper.

The economic and political interests of the two countries have diverged and converged in undulating waves over the past 200 years. The two economies are inextricably intertwined across a range of sectors, from natural resources and agriculture to advanced manufacturing. Around 70 per cent of Canadian exports go to the U.S., and the share of Canada’s merchandise imports from south of the border was around 59 per cent in 2025.

But for Canada, the relationship is more than just economic interdependence. The U.S. has a population of about 342 million and a gross domestic product about 10 times larger than Canada’s. That sets the stage for an asymmetrical relationship whose threads are woven into the fabric of trade and geopolitics.

For Canada, this can sometimes feel like vulnerability. And that vulnerability is increasingly being exploited by the U.S., creating a general feeling of existential crisis and entrapment.

Nevertheless, Canada can draw from its centuries-long experience to navigate the current headwinds. While the smaller of the two neighbours, it is not entirely dependent on the U.S. for influencing global events or harnessing international opportunities.

Canada has been, and still is, an influential power on the international stage. As a G7 nation, Canada is one of the key pillars in the scaffolding of the global economy. This global standing and international influence give it some room to manoeuvre.

Navigating an existential crossroads

First, in the international arena, Canada must diversify economically and geopolitically to build strategic resilience. Prime Minister Mark Carney is already moving on this front by agreeing to ease mutual tariffs with China. With negotiations to renew the Canada-U.S.-Mexico Agreement (CUSMA) slated for this year, a diversified trading economy will give Canada much greater leverage to navigate the vulnerabilities of asymmetry.

Second, Canada should draw from its record of championing a rules-based order. In recent years, the country has had to skilfully navigate the crossroads of projecting and defending its global and liberal-democratic values during periods of U.S. flirtations with populism, isolationism and anti-international rhetoric. As a middle power, it derives its strength from the rule of law and by presenting a united front with like-minded nations. A wider set of partners means more buffers against trade policy whiplashes and geopolitical shocks from the U.S.

Third, domestically, loosening inter-provincial trade flows, updating anachronistic regulatory frameworks and pursuing digital data sovereignty strategies should be high priorities to fire the full engine of the economy.

Similarly, as I’ve previously argued, Canada should use its comparative advantages in natural resources to create a strong, well-connected critical minerals supply chain. This would give it significant strategic leverage in the global economy as the world shifts to electrification and renewable energy.

Over the past two centuries, Canada has mastered the complex dance of asymmetry. However, the current crisis takes on an existential proportion that will require new agility, courage and decisiveness. It is an inflection point that will mark a consequential shift for the next generation.

Canada’s nimbleness and agility in navigating this political moment could be an model for other countries that must manoeuvre a world where the old rules no longer apply. It can serve as an example for small and middle powers who must navigate a world where great powers are increasingly belligerent.
