Reality check: The Supreme Court actually did the right thing in its child pornography ruling

Source: The Conversation – Canada – By Meg D. Lonergan, Contract Instructor and Doctoral Candidate, Legal Studies, Carleton University

The Supreme Court of Canada’s decision in the Attorney General of Québec v. Senneville struck down one-year mandatory minimum sentences for accessing or possessing child pornography. Immediately, politicians and commentators denounced the ruling.

Conservative Leader Pierre Poilievre, Ontario Premier Doug Ford and Alberta Premier Danielle Smith have urged Ottawa to invoke Section 33, also known as the notwithstanding clause, of the Charter of Rights and Freedoms. The clause allows Parliament or provincial legislatures to override certain Charter rights for five years.

Their alarm fits a broader pattern of constitutional populism in which politicians move to sidestep court rulings and Charter protections whenever they obstruct political objectives — whether that’s targeting the unhoused, trans rights, labour rights or now criminal sentencing.

One media commentator accused the Supreme Court of trying to “help” sex offenders, while Manitoba Premier Wab Kinew declared offenders should be “buried underneath prisons.” His reaction echoes last year’s episode in which he apologized for his caucus’s move to expel Mark Wasyliw — a criminal defence lawyer and NDP member of provincial parliament — after Wasyliw’s colleague, Gerri Wiebe, represented convicted sex offender Peter Nygard.

What the court actually did

In her seminal 1984 essay “Thinking Sex,” queer theorist and scholar Gayle Rubin observed that few political tactics are as effective at generating moral panic as invoking the need to “protect children.”

That remains true today, in part because voices across the political spectrum are vulnerable to the same knee-jerk, sensationalized responses whenever sexual harm involving children is at issue.

While the furious response to Senneville shows Canada in the grip of a new moral panic, the Supreme Court’s decision to strike down mandatory minimums for child pornography offences reflects constitutional fidelity — not leniency.

The Canadian Charter of Rights and Freedoms must apply to everyone if it’s to have any meaning at all. Section 12 of the Charter, in fact, guarantees that everyone has the right not to be subjected to cruel or unusual punishment.

Generally, mandatory minimums are constitutionally suspect, since they remove judicial discretion in sentencing based on the evidence and the specific situation at hand, and infringe upon the legal doctrine of stare decisis that requires precedence be followed.

In Senneville, the court held that mandatory minimums violate Section 12 Charter rights because they prevent judges from imposing proportionate, individualized sentences based on the facts of the case. The court also noted that Section 12 acknowledges innate human dignity and the inherent worth of individuals.

Proportionality, the Supreme Court emphasized, is a constitutional limit on state punishment, not a discretionary preference. At no point did the court diminish the gravity of child exploitation; on the contrary, it devoted an entire section in its ruling to detailing the profound harm caused by these offences.

This is consistent with the similar R. v. Friesen ruling in 2020, when the Supreme Court reaffirmed that the seriousness of child pornography does not erase the need for principled, proportionate sentencing. To cast this careful reasoning as “helping” sex offenders is not only wrong, it distorts the role of sentencing in a constitutional democracy and diminishes justice and rehabilitation in favour of punishment for its own sake.

A ‘flimsy’ hypothetical isn’t flimsy at all

An overlooked part of the majority decision in Senneville is that the appellants (the Attorney General of Québec) did not argue that, if the mandatory minimums were found to infringe the Charter’s Section 12, those minimums could be saved by Section 1.

Section 1 of the Charter guarantees that rights and freedoms are protected, but allows for “reasonable limits” that can be demonstrably justified in a free and democratic society.

This section gives governments the power to override Charter rights and freedoms when they can justify limiting them — most often in the name of protecting the rights and freedoms of others. Historically, this is what has made obscenity and hate speech laws constitutionally valid.

Many commentators claimed the Supreme Court relied on a “flimsy” and “far-fetched” hypothetical of an 18-year-old who receives an intimate image of a 17-year-old girl from a friend as one example of why the mandatory minimum sentences violate Section 12 of the Charter.

But there is nothing flimsy about this scenario. Canadian criminal justice scholars ranging from Alexa Dodge to Lara Karaian and Dillon Brady have shown that peer-based image-sharing among youth is common, and that criminal law routinely miscasts such behaviour through the lens of child porn, casting ordinary sexual expression as exploitation.

Karaian, in particular, shows how moral panic over “sexting” has long cast teenagers — especially girls — as simultaneously lacking agency and being responsible. This framing has helped create a legal landscape in which consensual, near-age image sharing is reinterpreted as criminal behaviour.

Familiar outrage

Since their introduction in 1993, Canada’s child-pornography laws have been criticized as overly broad.

One of the first tests came in the Eli Langer case, when police raided a Toronto art gallery and seized works — an early alarm bell about the law’s sweeping reach and capacity to criminalize artistic expression unconnected to exploitation.

The Supreme Court confronted these issues directly in the 2001 case R. v. Sharpe _[2001], ruling that existing child-pornography laws ensnared materials that posed no realistic risk of harm, including fictional writings and drawings. The court also carved out narrow exceptions to prevent criminalizing constitutionally protected expression.

Canadian law professor Brenda Cossman observed that moral panic around child pornography shields the law “from any and all criticism” to the point that: “Nothing can be said. And if it is, the speaker is denounced as a pedophile.”

The Senneville case reflects the realities of life, not some abstraction — and definitely not the carceral mindset that sees harsh punishment as moral and treats empathy as a weakness.

To normalize overriding Charter rights using the notwithstanding clause erodes not only public trust in judicial independence, but also the very rights and freedoms it enshrines.

The outrage of Poilievre, Smith, Ford and Kinew serves to assert their own moral authority and to repeat a familiar message: only incarceration protects the innocent. But if Canada is serious about keeping children safe, it must also invest in the social services, education and community supports that prevent harm.

As the Supreme Court itself reminded us in its ruling: “Criminal justice responses alone cannot solve the problem of sexual violence against children.”

Weak infrastructure leaves Jamaican schools devastated in the aftermath of Hurricane Melissa

Source: The Conversation – Canada – By Giselle Thompson, Assistant Professor, Faculty of Education, University of Alberta

The devastation in Jamaica caused by Hurricane Melissa exposed a harsh reality that’s been hidden in plain sight for decades — most schools were not structurally sound enough to sustain high winds, heavy rainfall and storm-surge flooding.

Almost 800 government schools were designated as community shelters before Hurricane Melissa descended. More than 600 were damaged when the hurricane hit. Roofs were blown off. Walls collapsed. Windows broke. Debris scattered everywhere.

Citizens found themselves in “shelters” that could not protect them from the elements and for this reason have had to find alternative living arrangements.

As education researchers based in the Jamaican diaspora whose combined work has examined the Jamaican education system, we are deeply concerned about the future of Jamaica’s schools and their ability to not only serve students and teachers — but to be safe havens in natural disasters.

These thoughts came to mind as we watched reels of footage of Hurricane Melissa’s destruction on social media with feelings of helplessness and regret.

Personal exchanges with friends, research collaborators and family members — who are fortunate to have electricity, cellular service or access to WiFi — told us about harrowing experiences on the ground, especially in communities in western and southern parishes such as Hanover, Westmoreland, St. James and St. Elizabeth.

Principals raise red flags

Previous research carried out by Giselle Thompson, the lead author of this story, has examined education spending in Jamaica and how members of the Jamaican diaspora in Canada support schools “back home” through formal and informal fundraising initiatives.

This research was undertaken in partnership with a primary school community, including the principal, teachers, students, families and neighbours in Hanover. They welcomed Giselle to work with them as a supply teacher, recess monitor and in other supportive roles they needed in 2018.

Being immersed in their everyday, under-resourced environment and having one-on-one conversations with them forged lasting personal and professional bonds that form the foundation of current research. It also offered insight into the structural inequities and related vulnerabilities inherent in the Jamaican school system.

At a media briefing before Hurricane Melissa struck, Jamaica’s minister of local government and community development criticized schools that were designated emergency shelters for electing not to open to the public.

But in June 2025, the Jamaica Gleaner reported that some principals raised concerns about the schools, saying they lacked adequate sanitation facilities, weren’t furnished with items that people would need in a shelter or were in need of repair.

These issues were recently echoed in a conversation with a Jamaican principal and research collaborator on Giselle’s current research project, funded by Social Sciences and Humanities Council of Canada and Killam Trusts. The study involves three public primary schools in Hanover and Westmoreland and examines Afro-Jamaican women teachers’ care work in these rural areas.

The principal noted her concerns were ignored when she brought them to the attention of personnel from the Office of Disaster Preparedness and Emergency Management (ODPEM) when her school was assessed and put on the emergency shelter list before the hurricane. Ninety per cent of ODPEM-designated shelters were schools, and close to 78 per cent of them were destroyed.

She also said the expectations of school staff during sheltering periods were unclear, and she was worried about the implications of leaving schools with scant resources unlocked without oversight.

Given the extensive and likely irreparable damages to her school, her decision to keep its doors closed may have been a life-saving move.

An account like this stands in contrast with the Ministry of Education, Skills, Youth and Information’s announcement that it had “taken deliberate and comprehensive steps to ensure the resilience of the education sector” and that the school “facilities are prepared for what is forecast to be an active hurricane season.”

Structural vulnerabilities

Approximately $5.5 million (J$628 million) was spent to prepare 204 schools for hurricane season in the 2025-26 academic year after Hurricane Beryl, a Category 4 storm, damaged 101 institutions in 2024.

This injection of capital was part of a more than $50 million (J$5 billion) government infrastructure preparation project for Hurricane Melissa’s descent.

Although not all schools were damaged in the hurricane, the high percentage of those impacted is a cause for concern. But the structural vulnerability of many Jamaican schools to the effects of climate change is nothing new.

It is directly linked to decades of under-resourcing, particularly in the “era of structural adjustment” (1977 to present) as the state has had to adopt severe austerity measures imposed by the International Monetary Fund and other international financial institutions to reduce its spending on public goods such as education.

Such fiscal belt-tightening is meant to help Jamaica and other heavily indebted countries placate their debt to external creditors. But this economic growth formula is seldom associated with social development.

The cost of inflation and the forced devaluation of the Jamaican dollar — additional austerity measures required by international financial institutions — have reduced government capacity to adequately resource school infrastructure.

Jamaica Teachers’ Association advocacy

Since 1977, the year that structural adjustment programs took root in Jamaica, education spending has fluctuated between five and six per cent of the country’s GDP. However, many stakeholders, including the Jamaica Teachers’ Association (JTA), have been vocal about the negative implications of inadequate spending on education for several years.

In 2024, the JTA president said such low spending puts the nation “woefully” behind. Much needed physical infrastructure and maintenance (and, we might add, books and other learning materials, nutritional programs and transportation) have lagged as a result.

It’s therefore not difficult to comprehend why the scale of Hurricane Melissa’s assault on schools was so significant.

Casting a hopeful vision

Through our ongoing engagements in Jamaica as scholars, educators, activists and community members, we have borne witness to, and are involved in, ongoing efforts to support numerous aged, decrepit and crumbling school structures, which are the result of the state’s neglect and weather systems that are growing increasingly harsh.

We write with hope for the future, one that includes new ecologically resilient schools for teaching and learning and where community members can shelter safely when natural disasters hit. This is essential because Jamaica, and the wider Caribbean region, is susceptible not only to hurricanes, but also floods, landslides, earthquakes and other hazards.

Yet we are not optimistic that the state alone can effect necessary changes because of its heavily indebted status, and therefore, relatively weak capacity.

4 urgent lessons for Jamaica from Puerto Rico’s troubled hurricane recovery – and how the Jamaican diaspora could help after Melissa


Although not an explicit admission, the creation of the National Education Trust in 2010 to raise funds and resources for schools, demonstrates this. The state has already begun its official solicitation of support from the international community.

But as members of the Jamaican diaspora in Canada, we urge others in our communities who are interested in supporting the reconstruction of schools in Jamaica to engage with principals, teachers, students and local community members directly so they are able to convey their institutions’ immediate and long-term needs.

This will increase the efficacy of our support and strengthen our ability to work together as Jamaicans at home and abroad.

Motherhood changes how women spend, save and think about money

Source: The Conversation – Canada – By Oriane Couchoux, Assistant Professor of Accounting, Carleton University

Mothers aren’t just losing the income, promotions and career advancements that we’ve known about for quite some time. They’re also quietly spending their own money, absorbing more day-to-day costs and making financial sacrifices that place them at a long-term disadvantage.

We already knew about the impact of motherhood on women’s income. A 2015 study by Statistics Canada shows that mothers earn 85 cents for every dollar earned by fathers. Ten years after the birth of their first child, mothers’ earnings are still around 34.3 per cent lower than they would have been without children.

But our research also reveals that women’s relationship with money is rewired with motherhood and that having children changes their financial decisions and spending habits.

Study participants describe two competing narratives when discussing their personal finances. On the one hand, they view motherhood as a financial project they must manage independently, within the limits of budgets and cost-benefit considerations. On the other hand, they also see motherhood as a role that requires financial sacrifice, where children’s needs and well-being take priority over all financial considerations.

The true cost of motherhood

Motherhood comes with a price. Studies have shown that becoming a mother negatively affects women’s finances and career.

Some research suggests that among other changes, their colleagues might start to perceive their competence and commitment to their professional work less favourably. Mothers also face intensified work-life balance pressures, often leading to part-time employment.

Women are 19 times more likely than men to cite “caring for children” as the primary reason for working part-time.

But beyond the well-documented motherhood penalty — the name given by social scientists to this phenomenon of workplace disadvantages — and the impact of motherhood on women’s income, our qualitative study reveals that motherhood alters the relationship women have with money.

We interviewed mothers living in the Canadian province of Québec to better understand how they manage their finances after having children, and found that motherhood reshapes how mothers spend and think about money.

When asked about how they manage expenses related to their children, participants in our study said they feel they must navigate competing societal expectations that drive them to juggle two narratives — seeing the financial aspect of motherhood as, one, a project to manage, and, two, as a sacrifice to make for their children.

Taking on the role of financial strategist

Mothers, on one hand, strive to be autonomous financial managers capable of developing financial strategies and making decisions considered economically responsible for their families.

As a study participant described:

“Everything goes through my account, I manage everything. I like it that way too. I’m a very meticulous person […] I like to be in control of the budget.”

This leads them to create “baby budgets,” tracking and comparing the prices of different diaper brands in spreadsheets, or setting up savings strategies for their children’s potential future education.

This vision of themselves as independent financial managers, coupled with their desire to fully take on the financial responsibilities of having children, sometimes leads participants in our study to shoulder certain child-related expenses on their own without sharing full details with their co-parent or asking the co-parent to contribute to everyday costs such as food, clothing or family activities.

Another person in the study explained:

“I know that I buy more things for the children. I put them on my card so I know that there are more expenses that I incur as extras … But, at the same time, that’s what I like. I love shopping for them. It’s a gift for me too. But sometimes, I find it a little annoying. I really devote myself a lot to the family, buying things for the house, the family.”

The cultural script of maternal self-sacrifice

Mothers also see themselves as the primary caregivers responsible for making financial sacrifices for their children.

Within this narrative, participants in our study tend to believe that being a good mother means putting their children first, doing everything possible to ensure their happiness and well-being and not tracking the time and money they devote.

As another shared:

“That’s what being a good mom is all about […] you can’t count that. You don’t count the time, being present, taking care of them, the activities, the clothes, everything. You don’t count the expenses, you’re the person they go to.”

This can lead mothers, for example, to put their children’s future ahead of their own, prioritizing education savings or splurging on non-essential items they believe will make their children happy over their own retirement.

This view of motherhood that normalizes financial sacrifice also appears in mothers’ reluctance to calculate the full cost of raising their children and the overall impact of these expenses on their own financial situation, as if determining the amount of money spent on a child were somehow incompatible with the maternal ideal of selfless devotion.

Gender inequality’s long-term financial fallout

This shift in women’s financial perspective highlights some factors behind the persistent gaps between women’s and men’s personal finances. In Canada, the gender pension gap is at about 17 per cent, meaning that “for every dollar of retirement income men receive, women get only 83 cents”.

The additional mental load carried by mothers doesn’t just cost them time and energy, it takes a real toll on their budgets too.

In fact, financial burdens can fall unevenly within couples and between co-parents. Many participants said that they focus on shouldering the financial responsibilities of motherhood independently, no matter the impact on their finances or the contribution from the other parent.

Over time, all of this can contribute to reduced savings and lowered retirement security for mothers, reinforcing the disparities in wealth accumulation and the gender pension between men and women.

Our findings highlight that the true cost of motherhood goes beyond what meets the eye and the need for a broader recognition of the financial labour that mothers bear. We, as a society, must better support them.

Worker honey bees can sense infections in their queen, leading to revolt

Source: The Conversation – Canada – By Alison McAfee, Postdoctoral Fellow, Applied Ecology, University of British Columbia; North Carolina State University

When the results of the Canada’s national honey bee colony loss survey were published in July 2025, they came as no surprise. According to the Canadian Association of Professional Apiculturists, an estimated 36 per cent of Canada’s 830,000 honey bee colonies had perished over the winter.

These figures used to make headlines. But after almost two decades of the same story ― colonies dying in the winter, beekeepers struggling to rebuild, somewhat succeeding, rinse and repeat ― the sad statistics are no longer news, and we are still working out why the cycle persists.

Now, we might be having a light-bulb moment. My colleague Abigail Chapman and I recently found that queen honey bees are infected with viruses that compromise their fertility and may get them ousted from their colonies. And that’s meaningful, because “poor queens” is the top-ranked cause of colony losses reported by Canadian beekeepers.

The life of a queen

A typical honey bee colony has a single queen at the helm, and she is solely responsible for laying thousands of eggs per day ― more than her own body weight ― to grow and replenish the colony’s population for years.

A healthy, productive queen also secretes pheromones that, like a chemical bouquet, signal her quality to the workers (sterile females who make up most of the colony’s population).

The queen cannot afford to get sick. She already barely has time to sleep, and the colony depends on her to remain reproductive. But she may indeed become sick.

Queen “autopsies” point to viruses

Our surveys of queens from members of the British Columbia Bee Breeders’ Association showed that “failing” (poor quality, unproductive) queens had a higher viral burden than their healthy counterparts. That is, they were either infected with more viruses, had more intense infections, or both. The failing queens also had smaller ovaries, a sign they could be less fertile.

But this doesn’t necessarily mean that viruses were the culprit or that queens were sick, per se. They could have been failing for other reasons that also made them more susceptible to infection.

So, Chapman designed an experiment to take a closer look. She infected queens with two common honey bee viruses, then measured the queens’ egg-laying activity and the mass of their ovaries.

Not only did the infected queens lay fewer eggs per day, they were less likely to lay eggs at all when compared with controls, at least during the monitoring period, despite all queens laying normally before the experiment. When we saw that the infected queens also had shrunken ovaries, just like the queens supplied by B.C. beekeepers, we knew we were onto something.

In the apiary, too, infected queens had problems. The worse a queen’s infection was, the more likely her workers were to begin rearing a replacement ― a process known as “supersedure.” If the upcoming replacement queen reaches adulthood, she will normally duel any other queen to the death, mate and become the new conveyor of eggs.

The workers’ dilemma

Superseding colonies are over three times more likely to perish when compared with healthy colonies, in part because there is no guarantee that the new queen will successfully mate. But from the workers’ perspective, supersedure is a necessary risk. If the old queen is compromised, producing a new one is the colony’s best chance at survival.

Normally, the queen produces and secretes a retinue pheromone — a blend of at least nine different chemical components — that, among other functions, inhibits workers from replacing her if all is well. But if one or more of those cues is disrupted by a viral infection, that could act like a red flag, we reasoned, signalling to the workers that the queen can’t lay her weight.

Our new data shows that this is the very process underlying the workers’ drive to replace infected queens. The infections caused a deficiency in methyl oleate ― one flower in the queen’s bouquet. This change encourages the workers to begin raising a new queen.

From beekeeper to queenkeeper

This validates beekeepers’ reports of having “queen issues” when infection levels are high and supports murmurs of queens not lasting as long as they used to. There are many other reasons why a queen may sputter, including pesticide exposure, extreme temperatures, poor mating and more. But viruses are a universal problem, and we did not previously understand the extent to which they could compromise queens.

Now that we do, colonies can be managed differently to better support the queen. There are currently no treatment options for honey bee viruses and there is a real need for commercial products, but luckily, there is still a way to act. Viruses are spread and sometimes amplified by varroa, a parasitic mite that can thankfully be controlled.

Deadlier than varroa, a new honey-bee parasite is spreading around the world


Varroa treatments ― which must be conducted two to three times per year to keep colonies alive ― already keep beekeepers up at night. Some may want to surrender at the thought of needing to be even more diligent.

But until an antiviral is developed and brought to market, stepping up varroa control is likely the best defence for keeping queens healthy and bringing down colony losses. Pollination of our fruits, nuts and seeds will depend on it.

Comment l’IA peut nous aider à dresser le portrait de la population parisienne d’il y a 100 ans

Au Réveil Matin, Maison Bénazet, café restaurant du 113 avenue Jean-Jaurès (XIX<sup>e</sup>), vers 1935.
Bibliothèque historique de la Ville de Paris

L’exposition « Les gens de Paris, 1926-1936. Dans le miroir des recensements de population », qui se tient actuellement, et jusqu’au 8 février 2026, au musée Carnavalet-Histoire de Paris, s’appuie sur les recensements de la population parisienne de 1926, de 1931 et de 1936, et contribue à renouveler le regard sur le peuple de la capitale dans l’entre-deux-guerres.


En France, des opérations de recensement sont organisées dès 1801, mais ce n’est qu’à partir de 1836 que des instructions spécifiques sont fournies pour procéder de manière uniforme dans toutes les communes du pays. Le recensement de la population est alors organisé tous les cinq ans, les années se terminant en 1 et en 6, jusqu’en 1946, à l’exception de celui de 1871 qui est reporté à l’année suivante en raison de la guerre franco-prussienne, et de ceux de 1916 et de 1941 qui ne sont pas organisés à cause des deux guerres mondiales.

Des données précieuses sur la population parisienne

Le premier but des recensements de la population est de connaître la taille des populations des communes pour l’application d’un certain nombre de lois. Ils permettent également de recueillir des informations sur l’ensemble des individus résidant dans le pays à un instant t pour en connaître la structure. Ces statistiques sont dressées à partir des bulletins individuels et/ou (selon les années) des feuilles de ménage (les feuilles de ménages récapitulent les individus vivant dans le même ménage et leurs liens au chef de ménage) remplies par les individus et publiées dans des publications spécifiques intitulées « résultats statistiques du recensement de la population ».

Archives de Paris : Cote D2M8 553

En plus de ces statistiques, les maires doivent également dresser une liste nominative de la population de leur commune. Mais Paris avait obtenu le droit de ne pas dresser ces listes. C’est le chef du bureau de la statistique parisienne, M. Lambert, qui décide de revenir sur cette exception dès 1926. Les listes nominatives de 1926, de 1931 et de 1936 sont donc les seules, avec celle de 1946, à exister pour la population parisienne.

Si Paris avait obtenu le droit de ne pas dresser ces listes, c’est en raison du coût d’une telle opération pour une population si vaste. La population parisienne compte, en effet, déjà près de 1,7 million d’habitants en 1861, un million de plus en 1901 et atteint son pic en 1921 avec 2,9 millions d’individus. Les données contenues dans ces listes sont particulièrement intéressantes, car elles permettent d’affiner considérablement les statistiques dressées pendant l’entre-deux-guerres.

Une base de données conçue grâce à l’IA

Ces listes, conservées aux Archives de Paris et numérisées puis mises en ligne depuis une dizaine d’années, ont déjà intéressé des chercheurs qui se sont appuyés dessus, par exemple, pour comprendre l’évolution d’une rue ou d’un quartier, mais elles n’avaient jamais été utilisées dans leur ensemble en raison du volume qui rend impossible leur dépouillement pour un chercheur isolé. Voulant également travailler à partir de ces listes – au départ, pour travailler sur la structure des ménages et notamment sur les divorcés –, j’avais moi aussi débuté le dépouillement à la main de certains quartiers.

La rencontre avec les informaticiens du Laboratoire d’informatique, de traitement de l’information et des systèmes (LITIS), Thierry Paquet, Thomas Constum, Pierrick Tranouez et Nicolas Kempf, spécialistes de l’intelligence artificielle, a changé la donne puisque nous avons entrepris de créer une base de données à partir de l’ensemble des listes nominatives de la population parisienne de 1926, de 1931 et de 1936 dans le cadre du projet POPP. Les 50 000 images, qui avaient déjà été numérisées par les Archives de Paris, ont été traitées par les outils d’apprentissage profond et de reconnaissance optique des caractères développés au LITIS pour créer une première base de données.

Les erreurs de cette première base « brute » étaient déjà très faibles, mais nous avons ensuite, avec l’équipe de sciences humaines et sociales – composée de Victor Gay (École d’économie de Toulouse, Université Toulouse Capitole), Marion Leturcq (Ined), Yoann Doignon (CNRS, Idées), Baptiste Coulmont (ENS Paris-Saclay), Mariia Buidze (CNRS, Progedo), Jean-Luc Pinol (ENS Lyon, Larhra) –, tout de même essayé de corriger au maximum les erreurs de lecture de la machine ou les décalages de colonnes. Ces corrections ont été effectuées de manière automatique, c’est-à-dire qu’elles ont été écrites dans un script informatique permettant leur reproductibilité. Ainsi, nous avons par exemple modifié les professions apparaissant comme « benne » en « bonne » ou bien les « fnène » en « frère ».

Adapter la base à l’analyse statistique

Il a ensuite fallu adapter la base à l’analyse statistique. Les listes nominatives n’avaient, en effet, pas pour vocation d’être utilisées pour des traitements statistiques puisque ces derniers avaient été établis directement à partir des bulletins individuels et des feuilles de ménage. Or, l’analyse statistique requiert que les mots signalant la même entité soient inscrits de la même façon. Cette difficulté est exacerbée dans le cas des listes nominatives : les agents avaient peu de place pour écrire, car les colonnes sont étroites. Ils utilisaient donc des abréviations, notamment pour les mots les plus longs comme les départements de naissance ou les professions.

Nous avons dû par conséquent uniformiser la manière d’écrire l’ensemble des professions, des départements ou des pays de naissance, des situations dans le ménage et des prénoms. Pour ce faire, nous nous sommes appuyés sur différents dictionnaires, c’est-à-dire des listes de mots correspondant à la variable traitée provenant de recherches antérieures ou d’autres bases de données. Ainsi, pour corriger les prénoms, Baptiste Coulmont, qui a travaillé sur cette partie de la base a utilisé les bases Insee des prénoms et des personnes décédées. Marion Leturcq et Victor Gay ont, par ailleurs, utilisé les listes des départements français, des colonies et des pays étrangers, tels qu’ils étaient appelés pendant l’entre-deux-guerres, ou encore la nomenclature des professions utilisées par la Statistique générale de la France (SGF).

Enfin, nous avons créé des variables qui manquaient pour l’analyse statistique que nous souhaitions mener, comme la variable « sexe » qui n’existe pas dans les listes nominatives (alors que le renseignement apparaît dans les fiches individuelles), ou encore délimiter les ménages afin d’en comprendre la composition. Ce travail de correction et d’adaptation de la base est encore en cours, car nous travaillons actuellement à l’ajout d’une nomenclature des professions – afin de permettre une analyse par groupes professionnels  –, ou encore à la création du système d’information géographique (SIG) de la base pour réaliser la géolocalisation de chaque immeuble dans la ville.

Retrouver des ancêtres

La base POPP ainsi créée a déjà été utilisée à différentes fins. Une partie de la base (comprenant les noms de famille – qui, eux, n’ont pas été corrigés –, les prénoms et les adresses) a été reversée aux Archives de Paris pour permettre la recherche nominative dans les images numérisées des listes nominatives. Ce nouvel outil mis en place au début du mois d’octobre 2025 – et également proposé en consultation au sein de l’exposition « Les gens de Paris, 1926-1936. Dans le miroir des recensements de population » – a déjà permis à de nombreuses personnes de retrouver leurs ancêtres.

Il nous a également été possible de fournir les premiers résultats tirés de la base POPP (confrontés aux résultats statistiques des recensements publiés) pour dresser des données de cadrage apparaissant sous forme d’infographies dans l’exposition (créées par Clara Dealberto et Jules Grandin). Ces résultats apparaissent également avec une perspective plus comparative dans une publication intitulée « Paris il y a 100 ans : une population plus nombreuse qu’aujourd’hui et déjà originaire d’ailleurs » (Ined, septembre 2025).

L’heure est maintenant à l’exploitation scientifique de la base POPP par l’équipe du projet dont le but est de dresser le portrait de la population parisienne à partir des données disponibles dans les listes nominatives des recensements de la population, en explorant les structures par sexe et âge, profession, état matrimonial, origine, ou encore la composition des ménages des différents quartiers de la ville.


L’autrice remercie les deux autres commissaires de l’exposition « Les gens de Paris, 1926-1936.

Global inequality is as urgent as climate change: the world needs a panel of experts to steer solutions

Source: The Conversation – Africa – By Joseph E. Stiglitz, Professor, Columbia Business School, Columbia University

Given the escalating scale of inequality in the world, shouldn’t countries be banding together to set up an international panel on the issue, along the same lines as the Intergovernmental Panel on Climate Change (IPCC), the United Nations body set up to assess the science related to climate change? The idea of setting up an international panel on inequality has been recommended by the G20 Extraordinary Committee of Independent Experts on Global Inequality.

The thinking behind the panel is set out in a report delivered to the G20 by the experts on the inequality committee. They argue that the proposed inequality panel would “support governments and multilateral agencies with authoritative assessments and analyses of inequality”. It wouldn’t make any recommendations for countries. Rather it would offer a menu of policies that could be used to address inequality. Panel leader and Nobel laureaute Joseph E. Stiglitz explains what’s behind the idea.

What are the report’s main findings on inequality?

Our report looked at the research on the state of inequality – and the conclusion should alarm us all. Wealth inequality is far worse than income inequality and has intensified in most countries over the last 40 years.

The global increase in income and wealth at the upper end of the scale is particularly worrying. The very richest people are amassing fortunes while ordinary people’s lives stagnate. For every dollar of wealth created since the year 2000, 41 cents have gone to the richest 1% of people, while just one cent has gone to the bottom 50%.

This wealth brings huge influence over economies and politics, threatening economic performance and the very foundations of democracy.

What does the report recommend the G20 countries do to deal with inequality?

Inequality is a choice. There are policies that can reduce it. These include more progressive taxation, debt relief, rewriting global trade rules and curbing monopolies.

Inequality in Africa: what drives it, how to end it and what some countries are getting right


Our committee found that there has been significant progress in tracking inequality’s scale, drivers and policy solutions. Nevertheless, policymakers still lack sufficient, dependable or accessible information on inequality.

There is a great institutional need for strong inequality analysis.

In 1988, governments set up the Intergovernmental Panel on Climate Change (IPCC) to assess the data and provide rigorous analyses to help governments tackle the climate emergency. Today, we are in an inequality emergency and need a similar global effort.

That is why our primary recommendation is to establish an International Panel on Inequality.

Drawing from the report, what do you recommend South Africa should do to reduce inequality?

South Africa has shown extraordinary leadership in focusing its G20 presidency on solidarity, equality and sustainability. This report is testament to that. We hope that South Africa will continue to champion our recommendations, particularly the establishment of an International Panel on Inequality.

Our committee chose not to comment on specific policies in specific countries. But our report contains a menu of policies which can tackle inequality. These include national measures like stronger competition laws, pro-worker regulation, investing in public services, and more progressive tax and expenditure policies.

L’IA fait peser des risques sur la sécurité nationale, la démocratie et notre système de santé… Quelques pistes pour les réduire

Source: The Conversation – in French – By David Rios Insua, Member of the ICMAT, AXA-ICMAT Chair in Adversarial Risk Analysis and Member of the Spanish Royal Academy of Sciences, Instituto de Ciencias Matemáticas (ICMAT-CSIC)

L’essor fulgurant de l’intelligence artificielle offre d’immenses opportunités, mais fait également peser des risques majeurs sur la démocratie, l’économie, la santé et la sécurité, que seuls des usages responsables, des systèmes plus sûrs et une régulation internationale ambitieuse pourront contenir.


L’intelligence artificielle (IA) s’invite désormais dans presque tous les aspects de notre vie. Nous profitons de ses avantages, comme l’accélération de la découverte de nouveaux médicaments ou l’avènement d’une médecine plus personnalisée grâce à la combinaison de données et d’expertise humaine, souvent sans même nous en rendre compte. L’IA générative, qui permet de créer rapidement du contenu et d’automatiser la synthèse ou la traduction via des outils comme ChatGPT, DeepSeek ou Claude, en est la forme la plus populaire. Mais l’IA ne se limite pas à cela : ses techniques, issues principalement de l’apprentissage automatique, des statistiques et de la logique, contribuent à produire des décisions et des prédictions en réponse aux demandes d’utilisateurs.

Si elle permet désormais d’accélérer des travaux de recherche qui exigeaient autrefois des années, elle peut aussi être détournée, par exemple pour identifier des composants utiles à la mise au point d’armes biochimiques. Elle ouvre la voie à des technologies comme les véhicules autonomes, mais en leurrant leur système de vision, on peut aussi transformer ces véhicules en armes… Les risques liés à l’IA sont multiples et spécifiques, et doivent être compris comme tels, ne serait-ce que parce que les systèmes d’IA sont complexes et s’adaptent avec le temps, ce qui les rend plus imprévisibles. Au rayon des menaces, on trouve notamment les données utilisées pour entraîner les modèles sous-jacents, puisque des données biaisées produisent des résultats biaisés.

Globalement, des acteurs malveillants peuvent utiliser l’IA pour automatiser des attaques à grande vitesse et le faire à très grande échelle. Lorsque l’intelligence artificielle contrôle des systèmes critiques, toute attaque peut avoir des conséquences considérables. Et comme les outils d’IA sont largement accessibles, il est relativement facile de les utiliser pour causer des dommages.

Menaces pour la démocratie et la santé

Plus tôt cette année, le Forum économique mondial de Davos a mentionné les « conséquences négatives des technologies d’IA » dans son Global Risks Report, en raison de leur capacité à perturber la stabilité géopolitique, la santé publique et la sécurité nationale.

Les risques géopolitiques tournent majoritairement autour des élections. Avec l’IA, les possibilités de désinformer se sont multipliées : en quelques clics, un utilisateur peut créer de faux profils, produire des fake news et en adapter le langage pour manipuler avec une précision inquiétante. L’élection présidentielle roumaine de 2024 a été suspendue en raison d’une ingérence étrangère manifeste via les réseaux sociaux. À mesure que l’IA progresse, ces risques ne feront que s’intensifier.

Les conséquences financières de l’IA ne peuvent pas non plus être ignorées. Des fausses informations générées par ces outils sont désormais utilisées pour manipuler les marchés, influencer les investisseurs et faire varier les cours des actions. En 2023, par exemple, une image générée par IA montrant une explosion près du Pentagone, diffusée juste après l’ouverture des marchés américains, aurait provoqué une baisse de la valeur de certains titres. Par ailleurs, des attaques « par exemples contradictoires » – qui consistent à tromper un modèle d’apprentissage automatique en modifiant les données d’entrée pour provoquer des sorties erronées – ont montré qu’il était possible de manipuler des systèmes de scoring de crédit fondés sur l’IA. Conséquence : des prêts étaient octroyés à des candidats qui n’auraient pas dû en bénéficier.

L’IA menace également les systèmes de santé. On se souvient, lors de la pandémie de Covid-19, de la vitesse avec laquelle les fake news sur les vaccins ou les confinements se sont propagées, alimentant la méfiance dans certaines communautés. Au-delà, des systèmes de santé fondés sur l’IA et entraînés sur des données biaisées peuvent produire des résultats discriminatoires, refusant des soins à des populations sous-représentées. Une étude récente du Cedars Sinai a ainsi montré que plusieurs grands modèles de langage (LLM) « proposaient souvent des traitements inférieurs » lorsqu’un patient en psychiatrie était « explicitement ou implicitement présenté » comme afro-américain. Enfin, l’IA a élargi la surface d’exposition des hôpitaux, qui deviennent des cibles de choix.

Nous devons également rester attentifs aux enjeux de sécurité nationale posés par l’IA. La guerre en Ukraine en offre une illustration claire. Le rôle militaire accru des drones dans ce conflit, dont beaucoup sont alimentés par des outils d’IA, est un exemple parmi tant d’autres. Des attaques sophistiquées utilisant l’IA ont mis hors service des réseaux électriques et perturbé des infrastructures de transport. De la désinformation appuyée sur l’intelligence artificielle a été diffusée pour tromper l’adversaire, manipuler l’opinion publique et façonner le récit de la guerre. Clairement, l’IA est en train de redéfinir les champs traditionnels de la guerre.

Son impact s’étend au domaine sociétal, du fait de la suprématie technologique acquise par certains pays et certaines entreprises, mais aussi au domaine environnemental, en raison de la consommation énergétique de l’IA générative. Ces dynamiques ajoutent de la complexité à un paysage mondial déjà fragile.

Une voie vers une IA plus sûre

Les risques liés à l’IA sont en constante évolution et, s’ils ne sont pas maîtrisés, ils pourraient avoir des conséquences potentiellement catastrophiques. Pourtant, si nous agissons avec urgence et discernement, nous n’avons pas à craindre l’IA. En tant qu’individus, nous pouvons jouer un rôle déterminant en interagissant de manière sûre avec les systèmes d’IA et en adoptant de bonnes pratiques. Cela commence par le choix d’un fournisseur qui respecte les standards de sécurité en vigueur, les réglementations locales propres à l’IA, ainsi que le principe de protection des données.

Le fournisseur doit chercher à limiter les biais et être résilient face aux attaques. Nous devons également toujours nous interroger face aux informations produites par un système d’IA générative : vérifier les sources, rester attentifs aux tentatives de manipulation et signaler les erreurs et les abus quand nous en repérons. Nous devons nous tenir informés, transmettre cette vigilance autour de nous et contribuer activement à ancrer des usages responsables de l’IA.

Les institutions et les entreprises doivent exiger des développeurs d’IA qu’ils conçoivent des systèmes capables de résister aux attaques adversariales. Ces derniers doivent prendre en compte les risques d’attaques adverses, en créant des mécanismes de détection s’appuyant sur des algorithmes et, lorsque cela est nécessaire, en remettant l’humain dans la boucle.

Les grandes organisations doivent également surveiller l’émergence de nouveaux risques et former des équipes réactives, expertes en analyse du « risque adversarial ». Le secteur de l’assurance développe d’ailleurs désormais des couvertures spécifiquement vouées à l’IA, avec de nouveaux produits destinés à répondre à la montée des attaques adverses.

Enfin, les États ont eux aussi un rôle déterminant à jouer. Beaucoup de citoyens manifestent leur souhait que les IA respectent les droits humains et les accords internationaux, ce qui suppose des cadres législatifs solides. Le récent AI Act européen, première réglementation visant à favoriser un développement responsable de l’IA en fonction des niveaux de risque des systèmes, en est un excellent exemple. Certains y voient une charge excessive, mais je considère qu’il devrait être perçu comme un moteur destiné à encourager une innovation responsable.

Les gouvernements devraient également soutenir la recherche et l’investissement dans des domaines comme l’apprentissage automatique sécurisé, et encourager la coopération internationale en matière de partage de données et de renseignement, afin de mieux comprendre les menaces globales. (L’AI Incident Database, une initiative privée, offre un exemple remarquable de partage de données.) La tâche n’est pas simple, compte tenu du caractère stratégique de l’IA. Mais l’histoire montre que la coopération est possible. De la même manière que les nations se sont accordées sur l’énergie nucléaire et les armes biochimiques, nous devons ouvrir la voie à des efforts similaires en matière de supervision de l’IA.

En suivant ces orientations, nous pourrons tirer le meilleur parti du potentiel immense de l’IA tout en réduisant ses risques.

High-rise living in Nairobi’s Pipeline estate is stressful – how men and women cope

Source: The Conversation – Africa – By Mario Schmidt, Associate Researcher, Max Planck Institute for Social Anthropology

Within sight of Kenya’s main international airport in Nairobi’s east, Pipeline residential estate stands out like a sore thumb. Composed almost entirely of tightly packed high-rise tenement flats, the estate has been described by the media as an urban planning nightmare. They point to its garbage problem, its waterlogged and frequently impassable streets, and the effect of dense living conditions on children’s health.

Pipeline’s transformation started roughly two decades ago. High-rise apartment blocks were a response to demand for low-cost rental housing in the rapidly urbanising capital. Individual private developers gradually converted the area, roughly 2km², into a dense, high-rise residential district. On average each block of flats hosts 200 or 300 tenants.

Pipeline is an example of how private sector developers can contribute to solving Nairobi’s housing crisis. But it’s also an example of how unregulated and poorly planned housing construction can have a negative impact on the social, economic and psychological well-being of households.

Pipeline is not the only tenement district in Nairobi. But it is one of the densest neighbourhoods in the city of over 4 million. The quality of buildings varies, but there are similarities:

  • rental flats mainly comprise single rooms with shared ablutions

  • unit design gives little attention to lighting, air circulation, or open space

  • tenants are forced into unfavourable rental relationships, where delays or default in payments can lead to water or electricity cuts.

The flats in Pipeline are almost exclusively inhabited by rural-urban migrants. They are attracted here by cheap accommodation and the promise of modernity. The flats have running water, tiled floors, individual electric meters and formal rental agreements.

We are researchers who study urban development, urban migration, and urban communities. Our fieldwork research sought to understand how the physical and social spaces created in neighbourhoods like Pipeline shape the experience of stress and pressure among men and women. We also looked at the strategies they apply to cope or reduce social, economic and romantic pressure.

Pipeline is a marked improvement from the options provided in Nairobi’s traditional informal settlements. Still, most basic services in the area are intermittent, or privatised. This is because the unplanned densification has outpaced the capacity of public infrastructure and services. This forces residents to pay for education, health, water, recreation and other services.

Nairobi’s slum residents pay a high price for low quality services


Many of these tenants are unemployed, or employed in low-wage industrial work, precarious gig work, or domestic work.

We found that men and women experience and try to cope with stress in diverse ways. Both men and women located the cause of their distress within their marital home. But the meanings and reactions to that stress diverged sharply in the migrant household.

We found that migrant men tend to experience stress in the form of pressure and migrant women in the form of tiredness.

Previous evidence points to the different ways in which stress is experienced based on biological differences between men and women. However, we propose that the tight coupling between men and pressure and between women and tiredness is the result of the expectation that men will be breadwinners. This drives men towards action and prevents women from expressing a will towards action.

Fieldwork and findings

We discovered our shared interest in studying Nairobi’s high-rise estates during a workshop on urban Nairobi.

Mario had carried out longitudinal ethnographic work with rural–urban migrants in Pipeline. His two-year-long fieldwork mostly took place in near-exclusively male spaces, such as gyms, barber shops and bars. Roughly 50 in-depth qualitative interviews revealed how men navigated urban lives that were increasingly defined by stress, pressure and exhaustion.

Miriam’s research focused on how Nairobi’s privately developed low-cost tenement precincts created environments of everyday urban dysfunction.

After the first meeting, we concluded that it would be beneficial to get a deeper understanding of women’s experiences of stress. This would help us to understand men’s and women’s experiences of stress and pressure. It would also enable us to compare how these different groups managed and coped with stress.

We designed a semi-structured questionnaire and conducted interviews with a dozen female residents. The interviewees spanned single and married women, members of a financial self-help group (chama), female neighbours who usually spent time together on balconies, a sex worker, and an entrepreneur who owned a hair salon.

Comparing the two sets of interviews provides ethnographic support for our hypothesis, which is that men and women tend to experience different types of stress: masculine “pressure” and feminine “tiredness”.

Masculine pressure is defined as an experience that provokes action. The pressure is intrinsically attached to the cause of stress and driven by the hope that overcoming it will promise social validation linked to the male provider model.

The male interviewees tended to engage in outward-oriented strategies to overcome this pressure. These include social drinking, extramarital affairs, or violent reaffirmations of gender identity. In this way, the form and design of Pipeline offered plentiful avenues for commercialised, stress-reducing activities.

How elites and corruption have played havoc with Nairobi’s housing


In contrast, feminine tiredness emerged as an experience that inhibited action. Female respondents were constrained from aggressive responses, lest they risk being branded immoral or losing vital male financial support.

Married women, or single parents, found themselves largely confined to the small apartments. Their inward-oriented coping strategies were sometimes identified as “doing nothing” or watching TV, or performing household tasks. This passive endurance of stress was also seen as a means to “persevere” (Kiswahili: kuvumulia). In some cases, women used intermediate semi-private spaces, such as balconies, chamas or church, to connect with neighbours.

Taken together, these responses and expectations structure the modes by which male and female migrants react to or attempt to mitigate or relieve stress. This stress is not only caused by poverty but by expectations of middle-class success, ideals of romantic family life and economic progression.

Conclusions

As yet, there are no policies or programmes that seek to reverse the complex challenges created through neighbourhoods like Pipeline. Kenya’s national affordable housing programme is focused on home-ownership solutions. However, with over 90% of the city’s population renting their dwellings, and 87% renting from private individuals, Nairobi needs a better solution for rental housing.

Kenya’s push for affordable housing is creating opportunities despite barriers


This could be through redevelopment and area-based upgrading, expansion of basic social and community services, incentives for private developers to incrementally upgrade their housing stock, rental and tenant protection legislation, and support for sustainable, communal, and cooperative housing alternatives spearheaded by citizens themselves.

Africa’s hidden stillbirth crisis: new report exposes major policy and data gaps

Source: The Conversation – Africa (2) – By Mary Kinney, Senior Lecturer with the Global Surgery Division, University of Cape Town

Nearly one million babies are stillborn in Africa every year. Behind every stillbirth is a mother, a family and a story left untold. Most of these are preventable, many unrecorded, and too often invisible. Each number hides a moment of heartbreak, and every uncounted loss represents a missed opportunity to learn and to act.

As a public health researcher specialising in maternal and newborn health, I have spent the past two decades working on strengthening health systems and quality of care across Africa. My research has focused on understanding how health systems can prevent stillbirths and provide respectful, people-centred care for women and newborns. Most recently, I was part of the team that led a new report called Improving Stillbirth Data Recording, Collection and Reporting in Africa. It is the first continent-wide assessment of how African countries record and use stillbirth data.

The study, conducted jointly by the Africa Centres for Disease Control and Prevention, the University of Cape Town, the London School of Hygiene & Tropical Medicine and the United Nations Children’s Fund, surveyed all 55 African Union member states between 2022 and 2024, with 33 countries responding.

The burden of stillbirths in Africa is staggering. Africa accounts for half of all stillbirths globally, with nearly eight times higher rates than in Europe. Even stillbirths that happen in health facilities may never make it into official statistics despite every maternity registry documenting this birth outcome.

Part of the challenge is that there are multiple data systems for capturing births and deaths, including stillbirths, like routine health information systems, civil registration and other surveillance systems. But these systems often don’t speak to each other either within countries or between countries. This data gap hides both the true burden and the preventable causes.

Despite advances in several countries to prevent stillbirths, large gaps remain, especially on data systems. Only a handful of African countries routinely report stillbirth data to the UN, and many rely on outdated or incomplete records. Without reliable, comparable data, countries cannot fully understand where and why stillbirths occur or which interventions save lives.

Strengthening stillbirth data is not just about numbers; it is about visibility, accountability and change. When countries count every stillbirth and use the data for health system improvement, they can strengthen care at birth for mothers and newborns and give every child a fair start in life.

Findings

The report was based on a regional survey of ministries of health. This was followed by document reviews and expert consultations to assess national systems, policies and practices for stillbirth reporting and review.

The report reveals that 60% of African countries have national and sub-national committees responsible for collecting and using stillbirth data, which produce national reports to respective health ministries. But data use remains limited. Capacity gaps, fragmented systems and insufficient funding prevents many countries from translating information into action.

To guide investment and accountability, the report categorises countries into three readiness levels:

  1. Mature systems needing strengthening, such as Kenya, Rwanda and Uganda. These countries have consistent data flows but need more analysis and use.

  2. Partial systems requiring support, where reporting mechanisms exist but are not systematically implemented, like Ghana, Malawi and Tanzania.

  3. Foundational systems still being built, including fragile or conflict-affected countries like South Sudan and Somalia. Here, policies and structures for data collection and use remain absent.

The findings show both progress and persistent gaps. Two-thirds of African countries now include stillbirths in their national health strategies, and more than half have set reduction targets. Nearly all countries report that they routinely record stillbirths through their health sectors using standard forms and definitions, yet these definitions vary widely. Most systems depend on data reported from health facilities. But the lack of integration between health, civil registration and other data systems means that countless losses never enter national statistics.

For example, if a woman delivers at home alone in Mozambique and the baby is stillborn, the loss is only known to the family and community. Without a facility register entry or civil registration notification, the death never reaches district or national statistics. Even when a stillbirth occurs in a health centre, the health worker may log it in a facility register but not report it to the civil registration system. This means the loss of the baby remains invisible in official data.

What this means

Stillbirths are a sensitive measure of how health systems are performing. They reflect whether women can access timely, quality care during pregnancy and at birth. But unlike maternal deaths, which are often a benchmark for health system strength, stillbirths remain largely absent from accountability frameworks.

Their causes, like untreated infections, complications during labour, or delays in accessing emergency caesarean sections, are often preventable. The same interventions that prevent a stillbirth also reduce maternal deaths. These improve newborn survival, and lay the foundation for better health and development outcomes in early childhood.

Accurate data on stillbirths can guide clinical care and direct scarce resources to where they are needed most. When data systems are strong, leaders can identify where and why stillbirths occur, track progress and make informed decisions to prevent future tragedies.

The analysis also highlights promising signs of momentum. Over two-thirds of countries now reference stillbirths in national health plans, an important marker of growing political attention. Several countries are moving from isolated data collection to more coordinated, system-wide approaches. This progress shows that change is possible when stillbirths are integrated into national health information systems and supported by investment in workforce capacity, supervision and data quality.

What’s needed

Africa has the knowledge, evidence and experience to make change happen.

The report calls for harmonised definitions, national targets and stronger connections and data use between the different data sources within and across African countries. Above all, it calls for collective leadership and investment to turn information into impact, so that every stillbirth is counted, every death review leads to learning and no parent grieves alone.

The author acknowledges and appreciates the partners involved in developing the report and the support from the Global Surgery Division at UCT.

Effets secondaires des chimiothérapies : une molécule française prometteuse pour lutter contre les neuropathies périphériques, dont souffrent près de 90 % des patients

Source: The Conversation – in French – By Laurence Lafanechère, Directrice de recherche CNRS, Université Grenoble Alpes (UGA)

Une nouvelle molécule capable de protéger les neurones des effets toxiques de la chimiothérapie, tout en renforçant l’efficacité de certains traitements anticancéreux, a été découverte et offre des résultats prometteurs chez l’animal. Une start-up a été créée pour continuer son développement et mener des études chez l’humain.


Picotements dans les mains et les pieds, brûlures, douleurs, perte de sensibilité, sensation d’engourdissement… Les neuropathies périphériques figurent parmi les effets secondaires les plus fréquents de la chimiothérapie, touchant jusqu’à 90 % des patients pour certains traitements. Leur sévérité conduit parfois les praticiens à ajuster, voire à réduire les doses de chimiothérapie, ce qui peut en diminuer l’efficacité.

Dans un cas sur quatre, ces atteintes nerveuses persistent des mois, voire des années après la fin du traitement. Elles rappellent alors chaque jour aux patients qu’ils ont eu un cancer – alors même que leurs cheveux ont repoussé et que les nausées ou la fatigue ont disparu. Aucun droit à l’oubli, même une fois la maladie vaincue

À ce jour, hormis le port de gants et de chaussons réfrigérants pendant les séances de chimiothérapie – une méthode pas toujours efficace et souvent désagréable –, aucun traitement préventif n’existe. Quelques médicaments palliatifs sont utilisés, pour atténuer la douleur, avec une efficacité modeste.

Notre équipe, en collaboration avec des chercheurs états-uniens et français, vient de franchir une étape importante avec la découverte d’un composé, baptisé Carba1, capable de protéger les neurones des effets toxiques de la chimiothérapie, tout en renforçant l’efficacité de certains traitements anticancéreux. Ces travaux viennent d’être publiés dans la revue Sciences Advances.

Une molécule, deux cibles

Carba1 appartient à la famille des carbazoles, une classe de molécules développée par les chercheurs du Centre d’études et de recherche sur le médicament de Normandie (CERMN), avec lesquels nous collaborons depuis plus de dix ans.

Nos travaux ont mis en évidence que Carba1 agit sur deux cibles principales.

Premièrement, Carba1 interagit avec la tubuline, la brique de base des microtubules. Selon les besoins de la cellule, ces briques peuvent s’assembler pour former soit des « câbles » capables de tirer et de séparer les chromosomes lors de la division cellulaire, soit des « rails » sur lesquels se déplacent des moteurs moléculaires transportant nutriments et organites comme les mitochondries, assurant ainsi la distribution de l’énergie et des ressources dans toute la cellule.

Ce système de transport est particulièrement essentiel dans les cellules nerveuses, dont les prolongements peuvent atteindre plus d’un mètre de longueur, par exemple les neurones qui partent du ganglion rachidien, près de la moelle épinière et vont innerver la peau des pieds. De nombreux médicaments anticancéreux, tels que le paclitaxel (Taxol) ou le docétaxel (Taxotère), ciblent déjà ces structures afin de bloquer la prolifération des cellules tumorales. Cependant, cette action n’est pas sans conséquence : les neurones, eux aussi dépendants des microtubules pour le transport de leurs constituants, en sont affectés, ce qui constitue l’une des causes majeures des neuropathies.

Nous avons montré que Carba1 modifie subtilement les microtubules : il perturbe leur extrémité, favorisant la liaison du paclitaxel. Cette interaction permet d’utiliser des doses plus faibles du médicament anticancéreux sans perte d’efficacité contre les tumeurs.

Mais ce n’est pas tout.

Des neurones plus résistants

Deuxièmement, en examinant plus en détail les propriétés de Carba1, nous avons découvert qu’il agit également sur un autre front : le métabolisme énergétique. Les neurones figurent parmi les cellules les plus gourmandes en énergie, et la défaillance bioénergétique est considérée comme l’un des principaux facteurs contribuant à la dégénérescence neuronale.

Nos résultats montrent que Carba1 active directement une enzyme clé, la nicotinamide phosphoribosyltransférase (NAMPT), qui relance la production de NAD⁺, molécule cruciale pour la génération d’énergie. Résultat : les neurones deviennent plus résistants au stress métabolique et survivent mieux aux agressions des agents chimiothérapeutiques.

Nous avons confirmé l’effet neuroprotecteur de Carba1 sur des cultures de neurones exposées à trois agents chimiothérapeutiques connus pour induire une neuropathie, via des mécanismes différents : le paclitaxel (ciblant les microtubules), le cisplatine (agent alkylant) et le bortézomib (inhibiteur du protéasome).

Contrairement aux cultures témoins où s’étendent des prolongements neuritiques lisses et vigoureux, dans les cultures traitées par ces médicaments, les prolongements présentent un aspect fragmenté, caractéristique d’un processus de dégénérescence. En revanche, lorsque les neurones sont exposés à ces mêmes traitements en présence de Carba1, leurs prolongements demeurent intacts, indiscernables de ceux des cultures non traitées. Ces observations indiquent que Carba1 protège efficacement les neurones de la dégénérescence induite par ces agents neurotoxiques.

Des résultats encourageants chez l’animal

Pour aller plus loin, nous avons testé Carba1 dans un modèle de neuropathie chez le rat traité au paclitaxel, développé par le Dr David Balayssac à Clermont-Ferrand (unité Neurodol). Ce traitement provoque une hypersensibilité cutanée : les rats réagissent à des pressions très faibles sur leurs pattes, un signe de douleur neuropathique. L’analyse histologique montre également une diminution des terminaisons nerveuses intra-épidermiques, tandis que le sang présente des taux élevés de NfL (chaîne légère de neurofilaments), marqueur de dégénérescence neuronale.

Lorsque Carba1 est administré avant et pendant le traitement, ces altérations disparaissent : les nerfs restent intacts, la concentration de NfL demeure normale et la sensibilité cutanée des animaux reste inchangée. Autrement dit, Carba1 protège les neurones de la dégénérescence induite par le paclitaxel. Signe rassurant, Carba1 n’impacte pas la croissance tumorale.

Comme les neurones, les cellules cancéreuses consomment beaucoup d’énergie. Il était donc essentiel de vérifier que Carba1 n’avait pas d’effet pro-tumoral et qu’il ne diminuait pas l’efficacité du paclitaxel. Pour le savoir, nous avons administré Carba1 seul, ou en association avec une dose thérapeutique de paclitaxel, à des souris porteuses de tumeurs greffées. Les résultats sont clairs : Carba1 n’a provoqué aucun effet toxique, ni altéré la santé générale des animaux, ni stimulé la croissance des tumeurs. Il n’interfère pas non plus avec l’action anticancéreuse du paclitaxel.

Une nouvelle voie vers des traitements mieux tolérés

Cette découverte est particulièrement enthousiasmante, car elle combine deux effets rarement réunis :

  • renforcer l’efficacité des médicaments anticancéreux de la famille du paclitaxel (taxanes) en permettant d’en réduire la dose ;

  • préserver les nerfs et améliorer la qualité de vie des patients pendant et après le traitement.

Avant d’envisager un essai clinique chez l’humain, plusieurs étapes restent indispensables. Il faut d’abord confirmer la sécurité de Carba1 chez l’animal, déterminer la dose minimale efficace et la dose maximale tolérée. Enfin, il sera nécessaire de mettre au point une formulation adaptée à une administration chez l’humain.

Cette mission incombe désormais à la start-up Saxol, issue de cette recherche, dont je suis l’une des cofondatrices. Si ces étapes – qui devraient s’étendre sur cinq ans au moins, selon les défis techniques et les levées de fonds – se déroulent comme prévu, Carba1 pourrait devenir le premier traitement préventif contre la neuropathie induite par la chimiothérapie – une avancée majeure qui pourrait transformer la façon dont les patients vivent leur traitement anticancéreux.

Carba1 incarne une innovation à l’interface de la chimie, de la neurobiologie et de l’oncologie. En associant protection neuronale et renforcement de l’efficacité thérapeutique, cette petite molécule pourrait, à terme, réconcilier traitement du cancer et qualité de vie. Pour les millions de patients confrontés à la double épreuve du cancer et de la douleur neuropathique, elle représente un espoir concret et prometteur.
