Iran’s exiled crown prince is touting himself as a future leader. Is this what’s best for the country?

As Iranian and US diplomats meet in Geneva for crucial negotiations to avoid a potential war, opposition groups in exile are sniffing an opportunity.

The Islamic Republic faces its greatest political crisis since its inception. US President Donald Trump is threatening an imminent attack if Iran doesn’t capitulate on its nuclear program. And anti-regime protesters continue to gather, despite a brutal government crackdown that has killed upwards of 20,000 people, and possibly more.

Talk of a future Iran after the fall of the Islamic regime has grown increasingly fervent. And buoyed by cries heard during some of the protests in Iran of “long live the shah” (the former monarch of Iran), the voices of royalists in the Iranian diaspora are everywhere.

But is a return of the shah really what Iranians want, and what would be best for the country?

What are the monarchists promising?

Iran’s monarchy was ancient, but the Pahlavi dynasty that last ruled the country only came to power in 1925 when Reza Khan, a soldier in the army, overthrew the previous dynasty.

Khan adopted the name Pahlavi, and attempted to bring Iran closer to Western social and economic norms. He was also an authoritarian leader, famous for banning the hijab, and was ultimately forced into exile by the British following the Anglo-Soviet invasion of Iran in 1941.

His son, Mohammad Reza Pahlavi, attempted to continue his father’s reforms, but was similarly authoritarian. Presiding over a government that tolerated little dissent, he was ultimately forced out by the huge tide of opposition during the Islamic Revolution of 1979.

Now, the exiled crown prince, 65-year-old Reza Pahlavi, is being touted by many in the diaspora as the most credible and visible opposition figure to be able to lead the country if and when the Islamic Republic collapses.

Pro-monarchy groups such as the US-based National Union for Democracy in Iran (NUFDI) have become vocal supporters of Pahlavi.

In early 2025, the NUFDI launched a well-coordinated and media savvy “Iran Prosperity Project”, offering what the group claimed was a roadmap for economic recovery in a post-Islamic Republic Iran. Pahlavi himself penned the foreword.

Then, in July, the group released its “Emergency Phase Booklet”, with a vision for a new political system in Iran.

Although the document is mostly written in the language of international democratic norms, it envisions bestowing the crown prince with enormous powers. He’s called the “leader of the national uprising” and given the right to veto the institutions and selection processes in a transitional government.

One thing the document is missing is a response to the demands of Iran’s many ethnic minority groups for a federalist model of government in Iran.

Instead, under the plan, the government would remain highly centralised under the leadership of Pahlavi, at least until a referendum that the authors claim would determine a transition to either a constitutional monarchy or democratic republic.

But students of Iranian history cannot help but note echoes of the 1979 Islamic Revolution. Ayatollah Ruhollah Khomeini had promised a more democratic Iran with a new constitution, and without himself or other clerics in power.

After the revolution, though, Khomeini quickly grasped the reigns of power.

Online attacks against opponents

Pahlavi and his supporters have also struggled to stick to the principles of respectful debate and tolerance of different viewpoints.

When interviewed, Pahlavi has avoided discussing the autocratic nature of his father’s rule and the human rights abuses that occurred under it.

But if Pahlavi tends to avoid hard questions, his supporters can be aggressive. At the Munich Security Conference in February, British-Iranian journalist Christiane Amanpour interviewed the crown prince.

Christiane Amanpour’s interview with Reza Pahlavi.

After the interview, Amanpour’s tough questions resulted in an explosion of anger from his supporters. In a video that has been widely shared on X, royalists can be seen heckling Amanpour, saying she “insulted” the crown prince.

In online forums, the language can be even more intimidating. Amanpour asked Pahlavi point-blank if he would tell his supporters to stop their “terrifying” attacks on ordinary Iranians.

While saying he doesn’t tolerate online attacks, he added, “I cannot control millions of people, whatever they say on social media, and who knows if they are real people or not.”

The rise of Reza Pahlavi: Iranian opposition leader or opportunist?


Do Iranians want a monarchy?

As I’ve noted previously, the monarchist movement also talks as though it is speaking for the whole nation.

But during the recent protests, some students could be heard shouting: “No to monarchy, no to the leadership of the clerics, yes to an egalitarian democracy”.

The level of support for the shah within Iran is unclear, in part because polling is notoriously difficult.

A 2024 poll by the GAMAAN group, an organisation set up by two Iranian academics working in the Netherlands, attempted to gauge political sentiment in Iran. Just over 30% of those polled indicated Pahlavi would be their first choice if a free and fair election were held.

But the poll doesn’t indicate why people said they wanted to vote for him. It also showed just how fragmented the opposition is, with dozens of names getting lower levels of support.

The future of Iran is very unclear at the moment. Even if the Islamic Republic were to be dislodged – a very big “if” – the transition could very well be chaotic and violent.

Would Pahlavi make a good leader? For many critics, his behaviour, and that of his supporters, call into question the royalists’ promises of a more liberal and tolerant Iran.

Cuba has survived 66 years of US-led embargoes. Will Trump’s blockade break it now?

Source: The Conversation – Global Perspectives – By James Trapani, Associate Lecturer of History and International Relations, Western Sydney University

After toppling Venezuela’s leader earlier this year, the Trump administration has turned its sights on Cuba. The near-total blockade of the island is now posing the greatest challenge to the government since the Cuban missile crisis in 1962.

Cuba is quickly running out of oil, creating a dire political and economic crisis for the island’s 11 million residents.

US President Donald Trump’s embargo has prevented any oil tankers from reaching the island for months. A ship carrying Russian fuel is now reportedly on the way to the island to attempt to break the blockade, but the US has seized other ships that have previously tried.

The Trump administration has also threatened tariffs on any nation that tries to send Cuba fuel, putting Latin American leaders in an uncomfortable position. Mexican President Claudia Sheinbaum has called out the embargo as “very unfair”, but she’s been careful not to antagonise Trump by putting an emphasis on the Cuban “people”, not the government.

This is not the first time the US has isolated Cuba, or coerced Latin American leaders to take part. Cuba has been under a US embargo for the past 66 years, which has stunted its economy and caused widespread human suffering.

The island has always found a way to get by, but can it survive this new round of American pressure?

Animosity grows in the 1950s

The Cuban Revolution caught the United States by surprise in 1959. During the Cold War, the US had supported dictatorships in Latin America, such as Cuba’s Fulgencio Batista, with political, financial and military support, creating widespread anti-US activism across the region.

After coming to power, revolutionary leader Fidel Castro instituted modest reforms to land tenure and infrastructure to support the impoverished people. Then-US President Dwight Eisenhower opposed these moves because of their impact on US commercial interests on the island. This opposition turned into a US embargo of Cuban sugar imports in 1960.

In response, Castro looked to the Soviets as an export alternative. Eisenhower retaliated by refusing to ship oil to Cuba, leading Castro to sign an oil deal with the Soviets and eventually nationalise American and British refineries. In 1961, Castro declared his adherence to “Marxism-Leninism”.

Castro and Cuba were hugely popular throughout Latin America. When the Cuban military defeated the CIA-trained force of exiled Cuban fighters at the Bay of Pigs in 1961, Castro was lauded for standing up to the US, though few knew of the military and intelligence support coming from the Soviets.

And when President John F. Kennedy began the campaign to remove Cuba from the Organisation of American States (OAS) in 1961, most Latin American democracies moved to block it.

To bring those leaders to his side, Kennedy used a carrot-and-stick approach. He proposed an “alliance for progress” to meet the “basic needs of the [Latin] American people for homes, work and land, health and schools”. But his government also passed the Foreign Assistance Act, which established a total blockade of the island and prohibited US aid to any country providing assistance to Cuba.

The OAS removed Cuba as a member the following year and, in 1964, voted to embargo all trade to Cuba, except food and medicine.

Life under the embargo

The embargo prevented Cuba from reaching the modern technological age. Instead, it existed in socialist bubble, emphasising the care of its people over economic development.

Nonetheless, Cuba’s Cold War economic growth was comparable to its neighbours. In 1970, the nominal GDP per capita for Cuba was US$645 (A$900), slightly lower than Mexico and about double the Dominican Republic. By 1990, it was US$2,565 (A$3,600), about 80% of Mexico’s and more than triple the Dominican Republic’s.

Cuba was not industrialised, but the country did reach full literacy before any other Latin American nation and extended health care to all Cubans. Cuba then exported its teachers and doctors throughout Latin America, and beyond.

However, life on the island was still difficult, especially after the collapse of the Soviet Union.

With no clear replacement for Soviet imports and subsidies, the economy began to buckle. From 1990 to 1994 (a time known as the “Special Period”), food production decreased by 40%, leading to food rationing, malnutrition and other health issues.

Protests broke out across the island in 1994 and some 35,000 Cubans fled on boats for Florida.

Cuba and the US after the Cold War

However, the end of the Cold War brought newfound sympathy and assistance from Cuba’s neighbours. Venezuelan President Hugo Chavez, for example, provided Cuba with oil in exchange for Cuban doctors.

Then, in 2009, the OAS voted to readmit Cuba and allow for regional trade and tourism again.

US President Barack Obama followed suit in 2014, saying the US embargo of Cuba had “failed”.

His administration then initiated what would become known as the “Cuban thaw”. Then-President Raul Castro visited Washington in 2015 and, the following year, Obama became the first US president to visit Cuba since 1928.

Obama did not end the embargo, but he did open the door to US tourism, providing a lifeline for Cuba’s economy.

Why is Trump punishing the island again?

Now, Trump is reimposing the Cold War-era embargo on the island and ramping up the pressure on President Miguel Díaz-Canel’s government.

The White House claims Cuba presents an “unusual and extraordinary threat” to the United States, saying the island is cooperating with “dangerous adversaries” on intelligence activities, chief among them Russia and China.

Russian President Vladimir Putin has condemned Trump’s embargo, saying “we do not accept anything like this”.

If Russian oil makes it to Cuba, more aid could follow. If that eventuates, the US will have invited Russia into its backyard again, laying the foundation for another Cold War-style stalemate, with the Cuban people once more trapped in the middle.

Morocco: ancient fossils shed light on a key period in human evolution

Source: The Conversation – Africa (2) – By Mohib Abderrahim, Chercheur en Préhistoire et conservateur principal des Monuments et Sites, Institut national des Sciences de l’Archéologie et du Patrimoine in Rabat

Could a Moroccan cave hold a crucial piece of the puzzle of human origins? Hominin fossils dating back 773,000 years discovered in the country are bringing new evidence to the debate about the last common ancestor of present-day humans (Homo sapiens), Neanderthals and Denisovans. The discovery points to a long evolutionary history in north Africa, much earlier than modern Homo sapiens. It also supports Africa’s central role in the major stages that shaped the human species.

Abderrahim Mohib is a prehistoric archaeologist, heritage curator, and associate professor and researcher at the National Institute of Archaeological Sciences and Heritage in Rabat. He’s one of the authors of a recent study that explains the significance of the discovery.


What did you discover and why does it matter?

Excavations have been underway since 1994 in the Hominid Cave at the Thomas Quarry I, south-west of the city of Casablanca in Morocco. A research programme called Prehistory of Casablanca working at the site is led by Morocco’s National Institute of Archaeological Sciences and Heritage and the French Ministry for Europe and Foreign Affairs.

The team has unearthed hominin fossils along with thousands of animal remains and around 300 artefacts made of quartzite and flint. The site looks like it was a den for large carnivores. This is supported by a hominin femur showing bite marks from a large carnivore, likely a hyena.

In addition to the femur, the set of hominin remains includes a nearly complete adult jaw, half of another adult jaw, a young child’s jawbone, cervical and thoracic vertebrae, and several teeth.

This discovery is significant. It sheds new light on a key period in human evolution. Fossils from this period are very scarce in Africa, Europe and Asia. These remains help document little-known populations between early Homo species and the more recent lineages. They are the oldest hominin fossils ever found in Morocco with a clear and reliable date.

In addition, the site is adjacent to another, older, site named Unit L in the same quarry. This site covers more than 1,000 square metres and dates back to 1.3 million years ago. It documents the oldest human occupation in Morocco. It is linked to the Acheulean material culture in north-west Africa.

How old are these early humans and how did you date them so accurately?

These fossils found in Casablanca were dated to around 773,000 years, using palaeomagnetism, the study of the Earth’s ancient magnetic field.

The sediments in Grottes à Hominidés have recorded changes in the Earth’s magnetic field. With very high-resolution sampling (every 2cm) we were able to identify the last geomagnetic reversal from a reverse polarity (Matuyama) to a normal polarity (Brunhes). This means that we have identified a period when the Earth’s magnetic field flipped. And that is a natural event that serves as a marker for dating geological and archaeological layers.

This reversal is a very solid and widely accepted chronological marker. What is extraordinary is that our fossil remains date precisely to the time of the reversal. This offers one of the most reliable datings of hominin fossils from the Pleistocene era (starting about 2.58 million years ago and often called the “Ice Age”). These data are consistent with the geological setting and palaeontological remains.

How does this change our understanding of modern human evolution?

The Casablanca fossils come from a time when Homo erectus spread out of Africa. It was also a time when older groups of hominins like the Australopithecus and Paranthropus died out.

In terms of shapes and features, the fossils show a mix of archaic traits typical of Homo erectus and more advanced traits closely related to Homo sapiens. They also fill an important gap in the African fossil record. Palaeogenetic data suggest a split between the African lineage to Homo sapiens and the Eurasian lineages that later produced the Neanderthals and the Denisovans.

The unique combination of primitive and more evolved features suggests that these individuals were in a population that lived close in time to this split.

This Moroccan population can be described as having advanced traits of Homo erectus. It has more evolved traits than older Homo erectus fossils found in Africa and Asia. But it lacks the full modern features seen in Neanderthals or anatomically modern Homo sapiens.

Until now, the fossils of Homo antecessor unearthed at the Gran Dolina site in Atapuerca, Spain were the only ones to show Homo sapiens-like traits. The fossils from the Grotte à Hominidés offer a new perspective.

They open up the possibility of an evolutionary link with the oldest known Homo sapiens fossils – those from Jebel Irhoud in Morocco, dated to around 315,000 years ago. These discoveries help clarify the emergence of the Homo sapiens lineage while reinforcing the idea that its deep roots are African.

So, based on their mix of archaic and derived traits, these finds support the deep African roots of Homo sapiens but also point to an African population close to the split between Eurasian and African lineages in the Middle Pleistocene.

Why is north Africa, and Morocco in particular, so important?

North-west Africa, along with east and southern Africa, represents one of the key regions where we currently have a new window into the evolution of Pleistocene hominins. The Mediterranean Sea likely acted as a major biogeographical barrier. It contributed to the divergence between African and Eurasian populations.

The Sahara desert’s size changed over time. It probably shaped how African populations were structured. The Moroccan fossils confirm how ancient and deep our species’ roots are in Africa. They highlight the key role of north-west Africa in the major stages of human evolution.

Will AI accelerate or undermine the way humans have always innovated?

Source: The Conversation – USA – By R. Alexander Bentley, Professor of Anthropology, University of Tennessee

Technological innovation has always relied on experts collaborating across time and geography. EtiAmmos/iStock via Getty Images

In graduate school, my experimental archaeology professor told a student to create a door socket – the hole in a door frame that a bolt slides into – in a slab of sandstone by pecking at it with a rounded stone. After a couple of weeks, the student presented his results to the class. “I pecked the sandstone about 10,000 times,” he said, “and then it broke.”

This kind of experience is known as individual learning. It works through trial and error, with lots of each. Also known as reinforcement learning, it is how children, chimpanzees, crows and AI often learn to do something on their own, such as making a simple tool or solving a puzzle.

But individual learning has limits. No matter how much someone experiments through trial and error, improvement eventually hits a ceiling. Humans have been throwing javelins for a few hundred thousand years, yet performance has largely plateaued. At the 2024 Olympics in Paris, the gold medal javelin throw was about 5% shy of Jan Železný’s 1996 record. The level of expert play in the strategy game Go was essentially flat from 1950 to 2016, when artificial intelligence changed the equation.

Throughout humanity’s existence, these limits on individual learning have not applied to technology. Since IBM’s Deep Blue defeated world chess champion Garry Kasparov in 1997, supercomputers have become a million times faster – and now routinely outperform humans in chess and many other domains.

Why is technological improvement so different? My work as an anthropologist on cultural evolution and innovation shows that, unlike individual performance, technology advances through combination and collaboration. As more people and ideas connect, the number of possible combinations grows superlinearly. Technological innovation scales with the number of collaborators.

My new book with anthropologist Michael J. O’Brien, “Collaborators Through Time,” reveals these patterns across human existence. It traces how 2 million years of technological traditions progressed through collaboration among specialists, across generations and with other species.

Expertise has been the key. Because traditional communities know who their experts are, specialization and collaboration have consistently underpinned human success as a species.

I’d summarize our insight into how technology keeps advancing as TECH: tradition, expertise, collaboration and humanity.

Traditions and expertise – the critical foundation

The longest technological tradition documented by paleoanthropologists was the Acheulean hand axe. The multipurpose stone tool was made by our hominin ancestors for almost a million years, including some 700,000 years at a single site in eastern Africa. People produced Acheulean tools through techniques they learned, practiced and refined across generations.

Later, small prehistoric societies of modern humans thrived on millennia of specialized knowledge, such as music, thatched roofs, seed cultivation, burying dead bodies in bogs, and making millet noodles and even cheese suitable for interring with mummies.

As early as 22,000 years ago, communities near the Sea of Galilee stored and used more than a hundred plant species, including medicinal plants. Shamans – ritual experts in medicinal knowledge and caregiving – helped their groups survive. Archaeological evidence from burial sites suggests these specialists were widely revered across thousands of years: One shaman woman was interred with tortoise shells, the wing of a golden eagle and a severed human foot in a cave in Israel.

Collaboration – knowledge spanning time and place

Traditional expertise alone does not advance technology. Technological progress occurs when different forms of expertise are combined.

The wheel may have emerged from copper-mining communities. One expert sourced copper from the Balkans, another transported it, another smelted it. By about 4000 B.C., additional specialists cast copper into an early wheel-shaped amulet: shaping a wax model, encasing it in clay, firing it in a kiln, pouring molten metal into the mold, then breaking the mold away.

Transport technologies reshaped ancient product networks. As communities across Eurasia and Africa built wheeled vehicles and ships, and raised domesticated horses and other pack animals, collaboration expanded across continents. Maritime and overland trade linked blacksmiths, scribes, religious scholars, bead makers, silk weavers and tattoo artists.

Expertise was often distributed between cities and their hinterlands, with cities functioning as hubs in cross-continental product networks. In ancient Egypt, no single community could produce a mummy. Mummification experts at Saqqara drew on a continental network that supplied oils, tars and resins, combining these materials with specialized techniques of antisepsis, embalming, wrapping and coffin sealing.

Around the world, states and empires – from the Indus Valley Civilization to the Vikings, Mongols, Mississippians and Incas – expanded these networks, serving as hubs that coordinated the exchange of raw materials, specialized knowledge and finished products. These exchanges could be highly specific: Chinese porcelain was shipped exclusively to 12th-century palaces in Islamic Spain via Middle Eastern traders who added Arabic inscriptions in gold leaf.

The scale has changed, but the structure has not. Today, within a global product space, an iPhone is assembled from a distributed network of specialized expertise and facilities.

Humanity – social learning

Today, AI may disrupt the millennia-long pattern of technological advancement through TECH. Most large language models generate statistically common responses, which can flatten culture and dilute expertise and originality. The risk grows as untapped high-quality training data – our reservoir of expertise – becomes scarcer.

This creates a feedback loop: Models trained heavily on low-quality content may degrade over time, with measurable declines in reasoning and comprehension. Some scientists now warn that humans and large language models could become locked in a mutually reinforcing cycle of recycled, generic content, with brain rot for everyone involved. The dystopian extreme is AI model collapse, in which systems trained heavily on their own output begin to produce nonsense.

Brain rot is one reason some AI pioneers now question whether large language models will achieve human-level intelligence. But that, I think, is the wrong focus. The key to continually improving AI models is the same one that has sustained human expertise for millennia: keeping human experts in the loop – the E in TECH. Thanks to a kind of “pied piper” effect, an informed minority can guide an uninformed majority who copy their neighbors.

In a classic experiment, guppies, following their neighbors, ended up schooling behind a robotic fish that guided them toward food. A recent study showed that traffic congestion eases when autonomous vehicles make up as little as 5% of cars on the road. In both cases, a small, informed minority reshaped the behavior of the whole system.

Like humans, large language models are social learners, and the learning can go in either direction. Designers can increase the likelihood that models continue to improve by ensuring they incorporate the accumulated lessons of human expertise across history. In turn, this creates the conditions for people and models to learn from one another.

In the 2010s, DeepMind’s AlphaGo rediscovered centuries of accumulated human Go knowledge through individual learning, then went beyond it by crafting strategies no human had ever played. Human Go masters subsequently adopted these AI-generated strategies into their own play.

Well-trained large language models can likewise summarize vast bodies of scientific information, help talk people out of conspiracy thinking and even support collaboration itself by helping diverse groups find consensus. In these cases, the learning flows both ways.

From Acheulean hand axes to supercomputers, human innovation has always depended on tradition, expertise, collaboration and humanity. If AI is tuned to find and trust expertise rather than dilute it, it can become humanity’s next great technology – on par with ancient writing, markets and early governments – in our long story as collaborators through time.

It’s never too late to learn a language – adults and kids bring different strengths to the task

Source: The Conversation – USA (2) – By Karen Stollznow, Research Fellow of linguistics, Griffith Centre for Social and Cultural Research, Griffith University; University of Colorado Boulder

Adult language learners have an understanding of grammar that can help them learn a new language. But they are also likely to feel more self-conscious as they do so. Bulat Silvia/iStock/Getty Images Plus

There’s a common assumption that if someone starts learning a language when they are very young, they will quickly become fluent.

Many people also assume that it will become much harder to learn a language if they start later in life.

Research into language learning shows that how old someone is when they learn a language does matter, but there is no point at which the ability to learn a language switches off.

While a young language learner can more easily acquire a native accent, adults retain the ability to learn new languages well into later life. Anyone can continue to learn and refine their vocabulary and grammar. Other factors, like motivation, can also play a role for learners of all ages.

I am a linguist and the author of a forthcoming book, “Beyond Words: How We Learn, Use, and Lose Language,” which looks at how language is learned, used and lost across a lifespan — and why age alone does not set hard limits on our linguistic abilities.

Instead, the strategies learners use, the outcomes they achieve most easily, and how others judge their progress can all change over time.

How age shapes language learning

Someone’s age can influence their language learning ability in a variety of ways.

Scientists sometimes talk about sensitive periods, or an early development window in which the brain is especially receptive to certain kinds of input.

When it comes to language, babies and children are particularly sensitive to the sound patterns of speech. They can also pick up on subtle phonetic distinctions that adults struggle to perceive or reproduce.

This helps explain why children who grow up bilingual often sound native in both languages. Accents, more than vocabulary or grammar, are where age-related differences are most pronounced.

Sensitive periods are found in other animals, too, especially birds, which have an early sensitive period for learning their species-specific song from an adult tutor.

After this window closes, learning a new language is still very much possible. But it usually takes more conscious effort and practice.

Studies also show that children exposed to a second language early, roughly before puberty, are more likely to develop nativelike pronunciation and intonation.

Brain imaging research shows that people who learn two languages early in life tend to process both languages in the same parts of the brain. Those who learn a second language later often use slightly different brain areas for each language.

In practical terms, early bilinguals are more likely to switch between languages effortlessly. Later learners may have to more consciously work through their second language, especially at first.

Benefits to learning a language as an adult

Pronunciation is only one part of language proficiency. Adults bring their own strengths to the task.

Unlike young children, adult learners already have a fully developed first language. They also have skills in reasoning and pattern recognition, as well as an awareness of how language works.

This allows adults to learn in a more deliberate way, as they study grammar rules and consciously compare languages. Adults are also more likely to rely on deliberate strategies, such as memorization, to learn a language.

In classroom settings, adults often outperform children in early stages of learning, particularly in reading and writing.

Language learning never truly stops. Even in adulthood, people continue to develop and refine their first language, shaped by their education, work and social environment, and how they use it day to day.

While it may be harder for adults to acquire a nativelike accent later in life, the good news is that grammar, vocabulary and fluency remain well within reach for most adult learners.

Benefits of learning a language as a kid

Children, meanwhile, tend to learn languages implicitly, through immersion and interaction, often without conscious attention to rules.

Social and emotional factors also play a major role in successfully learning a language.

Children are generally less self-conscious than adults and more willing to take risks when speaking.

Adults, by contrast, are often acutely aware of mistakes and may hesitate to speak for fear of sounding foolish or being judged.

Research consistently shows that being willing to communicate is a strong predictor of success in learning a new language. Anxiety, inhibition and negative feedback from others can significantly slow progress, regardless of age.

Accent, bias and social pressure

Other factors, like social pressure and discrimination, matter as someone tries to learn a new language.

Research into language and identity shows that listeners frequently associate accented speech with lower intelligence or competence, despite there being no connection between accent and cognitive ability.

Non-native speakers often experience stigmatization, discrimination and prejudice from native speakers.

This bias can discourage adult learners and reinforce the false belief that successful language learning means sounding native.

Motivation and aptitude matter, too

Motivation is another key factor that affects learners of all ages.

People learn new languages for many reasons: a new country, work, school, relationships or interest in another culture.

Research distinguishes between the different reasons people learn a language. Some are practical, like advancing a career or passing a test. Others are personal, such as wanting to connect with a community, culture or family.

Learners who feel a strong personal or emotional connection to the language are more likely to keep going even when it gets difficult, and they often reach higher levels of fluency than those without this connection.

Other people have a natural aptitude for learning a language and can pick it up easily. Perhaps they quickly notice sound patterns, or they can remember new vocabulary after hearing it once or twice.

Language aptitude is different from intelligence and varies from person to person. Aptitude makes success in learning a language more likely, but it doesn’t guarantee it.

Learners with average aptitude can still become very proficient in new languages as adults if they have consistent exposure, practice and motivation.

Different ages, different strengths

So is it better to learn a second language as a child or as an adult? Research suggests the more useful question is which aspects of language learning, such as pronunciation, fluency or long-term mastery, matter most.

Learning a new language early makes it easier to sound like a native speaker and to use the language smoothly, without having to think about the rules.

Learning that language later in life draws on adult strengths, such as planning, problem-solving and focused practice.

Ultimately, some people pick up languages quickly while others struggle, regardless of how old they are.

Beliefs about language learning shape education policy, parenting choices and how multilingual speakers are treated in everyday life.

When adults are told they’ve missed their chance to learn a language, many never bother to try. When foreign accents are treated as flaws, capable speakers can be unfairly discriminated against.

In fact, research shows that learning a language is possible at any age – it’s a lifelong, achievable journey, rather than a race against the clock.

In Colorado, from 2016 to 2020, 33 women who were pregnant or had recently given birth died from accidental overdoses. That’s more than died from traditional obstetric complications like infection, high blood pressure or bleeding combined.

More recent data shows an encouraging turnaround. The number of maternal overdose deaths dropped 60%, from 20 in 2022 to eight in 2023. I think one contributing factor might be increased access to naloxone for moms and families across the state.

As a perinatal addiction medicine physician, I specialize in taking care of pregnant people and families impacted by substance use disorder. Part of the care I provide is prescribing or distributing naloxone directly to patients and their family members. Naloxone is an over-the-counter medication that reverses the effects of opioid overdose.

In this video, the Substance Abuse and Mental Health Services Administration explains how naloxone, an opioid overdose-reversal medication, works in the body.

I served as a member and then co-chair of the Colorado Maternal Mortality Review Committee from 2017 to 2023. The committee reviews every death of a person in Colorado that occurs during a pregnancy or within 12 months of the end of a pregnancy. I personally reviewed the records of Colorado mothers who died from overdoses.

In Colorado, unintentional overdose and suicide have been the top two causes of maternal mortality each year since 2016. Nationally, the leading cause of maternal mortality is overdose, followed by homicide and then suicide.

Almost all overdose deaths occur in the community, outside of a medical center: in homes, cars and public places. In almost all circumstances, the review committee determined that if naloxone had been present, there was a good chance the mother would have survived.

Giving naloxone directly to patients and families

In 2023, The Naloxone Project, a nonprofit, started distributing naloxone directly to pregnant and postpartum moms and their families before leaving one of the 48 birthing hospitals in Colorado. The distribution is through a program called the Maternal Overdose Matters Initiative, also known as MOMs. The initiative was in direct response to the number of women dying from overdose during pregnancy or within a year after pregnancy.

The Naloxone Project was started in Colorado in 2021 by an emergency and addiction medicine physician. The project distributes naloxone directly to patients in Colorado hospital emergency rooms at risk for opioid overdose.

To date, The Naloxone Project has distributed more than 2,500 naloxone kits to 107 hospitals to give to patients across the state. The project also works to normalize the conversation about opioid overdose and prevention in health care settings. It’s grown, and now it has chapters in 16 states.

Naloxone can make recovery possible

The American Society of Addiction Medicine defines substance use disorder as “a treatable, chronic medical disease involving complex interactions among brain circuits, genetics, the environment and an individual’s life experiences.” People with the disease of addiction can, and do, recover – but only if they can stay alive to receive the support and treatment they need.

Research shows direct distribution of naloxone to people, families and communities saves lives. Access to naloxone gives people, including Colorado moms, a literal second chance at life.

Naloxone for more than substance use disorder

While people with substance use disorder are at the highest risk for overdose, they’re not the only ones. In 2024 alone, 1,603 people died of accidental opioid overdoses in Colorado.

Prescription opioids, such as oxycodone, hydrocodone and morphine, are commonly prescribed after a surgery, including C-sections. Opioids like these taken at home, even with a prescription, can be a source of accidental overdose. For example, a person prescribed these medicines may take too much at once or have an unexpected interaction with other medications or alcohol.

Accidental overdose also occurs in people the prescription was not intended for. That includes children who find medications in their homes. In Colorado, 17 children died from opioid overdoses in 2024.

Today, parents leaving the hospital with their new baby are given naloxone and education. They learn about safe storage and disposal of medications, how to recognize an opioid overdose, and how to give naloxone in case of emergency. Nasal-spray naloxone, the most common form provided by The Naloxone Project, is safe for all ages, including infants and toddlers.

Naloxone as a standard of care

Caring for people impacted by substance use disorder has convinced me that naloxone has a place in every home, school and workplace in our community.

Recognizing and responding to opioid overdose, including giving naloxone, is now a standard part of Basic Life Support training. Opioid overdose reversal is now seen as a critical, lifesaving skill comparable to CPR. Including this skill in training empowers bystanders to intervene.

For some of my patients, receiving naloxone during an overdose event gave them a chance to seek treatment and enter long-term recovery from substance use. Opioid use disorder treatment includes evidence-based medication for opioid use disorder, such as methadone, buprenorphine or naltrexone, residential or intensive outpatient treatment, individual therapy and peer support services, especially programs designed for pregnant and parenting moms.

How these facets of treatment come together in an individual person’s journey is unique. As much as I seek to individualize treatment plans, naloxone is for everyone. It can build a bridge between despair and hope — life and death — and as the data shows, it might be a part of saving Colorado moms’ lives.

The apocrypha, Christianity’s ‘hidden’ texts, may not be in the Bible – but they have shaped tradition for centuries

Source: The Conversation – USA (3) – By Christy Cobb, Associate Professor of Christianity, University of Denver

Not all versions of the Bible contain the same texts. oneclearvision/iStock via Getty Images Plus

Of Jesus’ 12 disciples, Saint Peter is one of the most important. In the Book of Matthew, Jesus declares that Peter is the “rock” on which “I will build my church,” and Catholic tradition considers him the first pope. Martyred in Rome in the first century, Peter asked to be crucified upside down so that he would not die in the same way as Christ.

However, that famous story is not in the Bible. It appears in a text called “Acts of Peter,” an “apocryphal” writing.

In ancient Greek, “apocrypha” means “hidden.” The word is used for texts that are not part of an approved set of religious books, especially Christian texts outside the official biblical canon.

Yet these books are not so hidden. Some of them, like Acts of Peter, have shaped Christian tradition for centuries and are read by many people today. These stories are not only fun to read, but also provide valuable information about ideas that interested early Christians.

In my research as a scholar of early Christianity, I read and interpret apocryphal texts to explore the ways that early Jews and Christians understood and practiced their religion.

Capital-A ‘Apocrypha’

When the word is capitalized, “Apocrypha” refers to a set of Jewish texts that are found in Roman Catholic Bibles, but they are not included in most Protestant Bibles.

These texts were valued within ancient Judaism, yet are not included in the Jewish sacred text the Tanakh. The Tanakh is similar to what Christians call the “Old Testament” or the “Hebrew Bible,” but there are many important differences, including the order of texts and the books that are emphasized.

Examples of these Apocryphal books include Judith, Sirach and the First and Second Books of Maccabees. The story of Hanukkah comes from the Books of Maccabees when Jewish rebels overcame an oppressive ruler and rededicated the temple in Jerusalem – a reminder of the Apocryphal books’ significance.

Most Christians viewed the Apocrypha as scripture until the Protestant Reformation of the 16th century. During this period, Protestant reformers such as Martin Luther argued that these texts were valuable to Christians but should not be viewed as scripture.

Today, Roman Catholicism and Orthodox Christianity affirm these texts as a part of their canon. Thus, not all Christian Bibles include the same number of books.

Lower-case ‘apocrypha’

The word apocrypha is also used to reference a second set of texts: Christian books that are not included in the New Testament, the faith’s officially recognized set of texts.

The New Testament canon usually includes 27 books, including the four gospels that describe Jesus’ life – Matthew, Mark, Luke and John – and Acts, which describes the works of the apostles who continued Jesus’ ministry after his death. The New Testament also contains many books of letters, or Epistles, written by early Christian leaders, and Revelation, a vision of the end of the world.

Yet early Christians wrote more than just these books. These additional texts are often grouped together and referred to as “Christian apocrypha.” They include a number of different genres.

For example, apocryphal gospels tell of the life, ministry and death of Jesus. One of the earliest is the Gospel of Thomas, probably written in the mid-second century. Unlike the New Testament gospels, Thomas does not include the death of Jesus. Instead, it is a collection of sayings, many of which are also found in the New Testament gospels.

There are other apocryphal gospels named after important people in Jesus’ life and ministry, such as the Gospel of Mary. Named after one of Jesus’ female followers, Mary Magdalene, it notes that Jesus loved her more than any other woman.

Another genre is “apocryphal acts” – books that expand upon stories of the apostles who followed Jesus. One example is the Acts of Thecla, a story about a female follower of Jesus who was called to preach and teach the gospel. There are also apocryphal letters, apocalyptic texts and passion narratives that add details to the death and resurrection of Jesus.

One way to think about Christian apocryphal texts is as fan fiction written about the stories found in the New Testament. The New Testament gospels do not provide information about Jesus’ experience as a child. Yet there are apocryphal texts called “infancy gospels” that fill in the gaps, saying more about Jesus’ birth and how he navigated his perceived divine powers. In the “Infancy Gospel of Thomas,” the young Jesus brings a set of clay birds to life, rebukes his teacher and even kills his playmates.

Creating the canon

So why were these interesting texts not included in the New Testament?

The process of canonization was a slow one. Contrary to popular belief, there was not one early meeting of Christians to vote on which books should be in the New Testament. Instead, much of the canon developed slowly, as widely read texts circulated among the people and were read aloud.

Theology seems to have been a primary factor behind how the canon took shape. Early Christians fiercely debated things like Jesus’ nature: whether he was divine, human or both. Bishops and priests often challenged texts that did not conform with what became orthodox doctrine. Early Christians tended to read, copy, share and preserve the texts whose contents they already agreed with.

Even still, some Christians continued to read and value apocryphal texts. One of the oldest complete versions of the New Testament, the Codex Sinaiticus, dates to the fourth century and includes two apocryphal texts: the Shepherd of Hermas and the Epistle of Barnabas.

Christians throughout the years have continued to read and value the texts of the apocrypha. Medieval artwork illustrates this, as many stories only found within apocryphal texts are depicted on the ceilings of basilicas, on altarpieces and in paintings. Today, many Christians remain enthralled by these stories, which fill in gaps from the New Testament and provide intriguing details of the lives and ministries of biblical figures.

Minneapolis united when federal immigration operations surged – reflecting a long tradition of mutual aid

I’ve been living in Minneapolis and working on my doctoral dissertation about local religious communities since 2019.

It’s given me a chance to personally witness how the COVID-19 pandemic, the aftermath of the killing of George Floyd by police officers, and the surge in federal law enforcement presence have fostered grassroots networks of what’s known broadly as “mutual aid.”

Simply put, mutual aid is when communities work together to distribute resources people need to survive, whether it’s food, shelter, clothing or help paying bills. Unlike charity or government assistance, mutual aid is decentralized, grassroots-led and not channeled through nonprofits or government agencies.

One reason why mutual aid flourishes in Minnesota is that it has deep roots in the state.

Enduring ‘Operation Metro Surge’

Citing an already prosecuted case of fraud in which some of the perpetrators were Somali American citizens residing in Minnesota, the Trump administration dispatched Immigration and Customs Enforcement and Customs and Border Protection agents to the Twin Cities in late 2025.

Within weeks, the number of federal agents in what the Department of Homeland Security dubbed “Operation Metro Surge” had topped 3,000, outnumbering those in local police forces and ushering in widespread fear and uncertainty.

Local mutual aid networks quickly mobilized in response to these federal operations. Immigrant advocacy organizations have organized constitutional observer trainings and distributed “know your rights” information on flyers.

As in other cities, including Los Angeles and Chicago, “ICE Watch” volunteers in Minneapolis sound 3D-printed whistles and car horns to alert neighbors during ongoing raids. Constitutional observers document key details and provide support to neighbors.

The participants come from every walk of life.

Churches and sex shops alike have pivoted away from their routines to distribute food, diapers, cash and other household items that immigrant households need. Residents with disposable income have organized targeted “cash mobs” to support struggling local businesses.

Crowd-sourced campaigns have directed rent money to families whose breadwinners are afraid to go to work.

Federal agents have targeted schools and bus stops, apprehending adults and children. Parents and neighbors across the region have begun patrolling school drop-off zones to shield students from federal immigration actions.

The North Star State’s heritage

The local grassroots resistance to Operation Metro Surge came as no surprise to me. Mutual aid has deep roots in Minnesota, and this history is closely connected to the violence of European settlement and American expansion.

Minnesota’s harsh winters have always demanded cooperation and neighborliness, not merely as an expression of “Minnesota Nice” – the state’s reputation for a warm, if guarded, way of interacting – but as a survival strategy that predated the first European arrivals in the 17th century.

Generosity, respect and compassion are central values among Dakota and Ojibwe people, Minnesota’s original inhabitants.

From when French fur trappers and Catholic missionaries first made their way to the Great Lakes in the 17th century until the onset of a population boom in the mid-19th century, Indigenous inhabitants sustained relatively stable and mutually beneficial relations with colonial powers.

The North Star State’s Minnesota Nice reputation has long encompassed progressive politics; a polite, if guarded, interpersonal demeanor; and a hearty neighborliness formed out of necessity during frigid winters.

Many people in Minnesota trace their heritage back to a 19th-century northern European immigration wave.

Undergoing demographic changes

After Minnesota gained statehood in 1858, a series of broken treaties, armed conflicts and several laws forced Indigenous people onto reservations, opening up large swathes of land for white settlement. Immigrants from countries like Sweden, Norway and Germany settled in Minnesota in hopes of better opportunities than they had back home. Catholic and Lutheran churches and mutual benefit societies preserved cultural heritage, combated isolation and shaped the new state’s religious culture for generations.

In 1850, 6,100 people lived in the Minnesota Territory. By 1900, the state’s population had reached more than 1.75 million residents, 37% of whom were foreign-born.

Beginning in the 1970s, Minnesota welcomed Somali and Hmong refugees, as well as immigrants from Latin America. Robust social services and Catholic and Lutheran refugee settlement agencies have helped to integrate new arrivals, many of whom fled their countries of origin in response to economic crises and geopolitical instability.

While more than 4 in 5 Minnesotans today are white, the Minneapolis-St. Paul region remains far more diverse in terms of race, religion and national origin.

The seven-county region is 72% white, 10% Black or African American, 8% Asian or Pacific Islander, 7% Latino and just under 1% Native American, according to the 2022 American Community Survey. White people make up just over 50% of the population in both Minneapolis and St. Paul. At just under 20%, Black people constitute a higher share of population in Minneapolis. In St. Paul, about 1 in 5 people are Asian, mainly Hmong and other people of Southeast Asian descent.

Minnesota’s religious landscape is changing too. Since 2000, for example, the share of Muslim Minnesotans has grown from 1% to 3%.

Hmong and Somali Minnesotans play an increasingly prominent role in Twin Cities politics. The Trump administration has harangued the region’s Somali American elected officials, including Rep. Ilhan Omar of Minneapolis, especially during its immigration crackdown.

Welcoming donations

The fatal shooting of Minneapolis resident Renee Good on Jan. 7, 2026, by ICE agent Jonathan Ross further galvanized the local resistance. While it is unclear if Good was acting as part of a local ICE Watch group, attendance at observer trainings increased in the following weeks.

A few weeks after Good died, on Jan. 23, more than 50,000 people marched in frigid weather through downtown Minneapolis to demand “ICE out!”

In what organizers billed “A Day of Truth and Freedom,” over 700 local businesses closed in solidarity. An estimated 100 clergy were arrested outside the city’s airport, where they decried daily deportation flights to detention facilities.

The outrage increased when, the next morning, border patrol officers shot and killed Alex Pretti, a South Minneapolis Veterans Administration nurse who was documenting ICE actions at the intersection of 26th Street and Nicollet Avenue.

In response, local businesses sheltered people from the chemical that agents deployed. Residents of the neighborhood opened warming stations and distributed granola bars, hot water and hand warmers to mourners.

One organizer insisted they were not accepting payments for these goods and services, although donations were welcome.

Lasting harm

The federal government said it had detained over 4,000 people as of Feb. 4. With public pressure welling up, Tom Homan, Trump’s border czar, announced on Feb. 12 that Operation Metro Surge would come to an end.

As of Feb. 25, ICE is less visible in South Minneapolis. But locals across the region are well aware of the ongoing presence in suburban areas, where agents are reportedly using new tactics.

Even if the immigration agents do completely clear out, the damage caused will surely be long-lasting.

Children like 5-year-old Liam Conejo Ramos, who was taken from his suburban Twin Cities home and flown to a detention facility in Dilley, Texas, have received inadequate food and limited access to recreation while held there, according to ProPublica’s investigative reporters. The American Academy of Pediatrics has called attention to the lasting harms of juvenile detention.

South Minneapolis’ Lake Street corridor, home to over 1,000 immigrant-owned small businesses, has lost over US$46 million in revenue since December. Local leaders estimate that the citywide economic damage exceeds $200 million.

But Minneapolis residents are carrying on the state’s long-standing tradition of solidarity through mutual aid.

La Jefa: the wife of slain drug kingpin El Mencho and the women at the heart of the cartels

Source: The Conversation – UK – By Adriana Marin, Lecturer in International Relations, Coventry University

Women often play a central role in the business activities of organised crime. Krakenimages.com/Shutterstock

The death of Nemesio “El Mencho” Oseguera Cervantes, the leader of the Cártel Jalisco Nueva Generación (CJNG), on February 22 was immediately framed as the fall of a narco kingpin. Images of gun battles, torched vehicles and retaliatory violence dominated headlines. Commentators spoke of a power vacuum, of fragmentation, of the possible weakening of one of Mexico’s biggest cartels.

It was presented as the removal of a singular, hyper-violent male figure at the apex of a criminal empire. But this framing tells us more about how we imagine organised crime than about how it actually works.

The obsession with kingpins rests on a dramatic understanding of cartel power: a gun in one hand, territory in the other, masculinity performed through brutality. El Mencho embodied that image.

Yet cartels are not sustained by spectacle alone. They endure because someone moves the money, launders the profits, manages the assets, cultivates legitimate fronts and binds networks of loyalty through family. In the case of CJNG, that figure was not only El Mencho. It was also, allegedly, his wife Rosalinda González Valencia.

González has often been described as La Jefa (the Spanish feminine form of “the boss”). It’s a label that gestures toward authority while still situating her in relation to her husband. But she was not simply the spouse of a drug lord. She came from the Valencia family, historically linked to Los Cuinis, a network deeply embedded in CJNG’s financial operations.

Authorities have alleged that she oversaw dozens of businesses, property holdings and shell companies tied to the cartel’s laundering apparatus. Arrested multiple times and jailed for five year for money laundering in 2021 (she was released last yearfor good behaviour), she occupied the grey zone where criminal capital bleeds into the legal economy. If El Mencho represented the cartel’s violent face, González represented its economic spine.

This is where gender matters. Organised crime is routinely portrayed as an arena of exaggerated masculinity. Women appear in these stories as victims, girlfriends, trafficked bodies or glamorous accessories.

Even when they are prosecuted, they are often framed as appendages: “the wife of”, “the daughter of”, “the partner of”. Such language, while often difficult to avoid, obscures the structural reality that many cartels operate through kinship capitalism, where family is not sentimental but strategic.

Within these systems, wives are not incidental. They help keep the business secrets in environments where betrayal is fatal. In patriarchal criminal orders, loyalty is policed through blood ties.

A spouse managing accounts is not a deviation from power but an extension of it. Gender does not exclude women from authority, but rather reshapes how that authority is exercised and perceived.

The sensational truth is this: violence may conquer territory, but finance governs it. And, as the International Crisis Group – a western non-government organisation which aims to prevent conflict – spelled out in a 2023 report, finance in many cartels is deeply gendered.

This does not mean romanticising women’s roles within organised crime. Nor does it suggest emancipation through criminality.

The power reportedly exercised by figures like González tends to be situated within male-dominated hierarchies and violent systems that are also responsible for extreme forms of violence against women, including femicide and sexual exploitation. The same structures that allow elite women to wield financial authority simultaneously reproduce brutal patriarchal control elsewhere. That contradiction is not accidental – it is the way things work.

El Mencho’s death exposes that contradiction. When the state removes a male leader, the assumption is that the organisation will collapse or descend into chaos. But cartels are not merely built around a single dominant figure. They are hybrid enterprises combining coercion, corporate structures and family governance. The removal of the public face does not automatically dismantle the private architecture.

Hidden power structure

The question, then, is not simply who will pick up the gun, but who keeps the books. Who maintains the corporate fronts? Who sustains cross-border financial channels? Who negotiates the transformation of illicit profits into legitimate capital? These are not secondary concerns. They determine whether an organisation fragments or adapts to a leader’s death or imprisonment.

By centring El Mencho alone, media narratives are perpetuating a blindness to the role of women in cartels. They equate power with violence and masculinity with control, leaving the economic and relational dimensions of authority under-analysed.

Yet organised crime studies increasingly demonstrate that durability lies in governance, not gunfire. Governance depends on management, financial oversight, logistical coordination, and embedded social networks. These functions are often feminised – not because women are naturally suited to them, but because patriarchal systems allocate them in ways that render them less conspicuous and therefore less targeted.

There is something unsettling about recognising the strategic authority of cartel wives. It complicates comfortable binaries of victim and perpetrator. It challenges the idea that women in violent systems are either coerced or just marginal figures.

But in Italy, Rafaella D’Alterio reportedly maintained the operational and financial coherence of her Camorra clan following her husband’s death. She did this – not through spectacular violence – but through administrative control, alliance-building, and family networks. Her case, as many others, underscores that durability often lies in governance rather than gunfire.

Decapitation strategies – killing a cartel’s leader – are politically dramatic and symbolically powerful. But they rest on the assumption that criminal organisations are vertically dependent on a single male. If financial governance and kinship networks remain intact, the system may regenerate.

El Mencho’s death is therefore both a rupture and a revelation. It is a rupture in the sense that the figurehead of one of the world’s most powerful cartels has fallen. But it is also a revelation of how narrow our understanding of organised crime remains.

We fixate on the spectacle of masculine violence while overlooking the quieter, gendered infrastructures that sustain it. To understand cartels solely through their kingpins is to misunderstand them. Power in organised crime does not reside only in the man with the gun, but also in the women who, whether publicly acknowledged or not, often stand at the centre of that architecture.

Sclérose en plaques : quand le cerveau est influencé par l’intestin

Source: The Conversation – in French – By Vito Ricigliano, Neurologue et chercheur en neurologie, Université Paris-Saclay; Commissariat à l’énergie atomique et aux énergies alternatives (CEA)

Mieux comprendre comment le microbiote de l’intestin agit sur le cerveau pourrait ouvrir de nouvelles perspectives pour ralentir la progression de la sclérose en plaques, favoriser la réparation des cellules nerveuses et améliorer la qualité de vie des patients.


Et si l’un des moyens de lutter contre la sclérose en plaques se trouvait du côté de l’intestin ? Depuis quelques années, les scientifiques qui travaillent à mieux comprendre cette maladie – qui se caractérise par la destruction de la myéline, la gaine protectrice des neurones – manifestent un grand intérêt pour cet organe, généralement plus connu pour son rôle dans la digestion.

Il a en effet été découvert que le microbiote intestinal – l’ensemble des milliards de bactéries qui colonisent notre intestin – joue un rôle clé dans l’inflammation et la réparation neuronale. Ces microbes produisent des molécules qui interviennent à différents niveaux dans l’organisme : elles régulent les cellules immunitaires, telles que les lymphocytes T, soutiennent les cellules responsables de la formation de la gaine de myéline ou encore influencent le rythme circadien (cycle veille-sommeil) et le drainage des déchets cérébraux, lesquels doivent être éliminés pour maintenir un environnement sain dans le cerveau.

Ces diverses interactions permettent notamment de limiter les réactions auto-immunes, qui sont à la racine de la sclérose en plaques.

Les causes de la sclérose en plaques toujours en cours d’investigation

La sclérose en plaques est une maladie chronique du système nerveux central (cerveau et moelle épinière) au cours de laquelle le système immunitaire attaque la myéline, la gaine protectrice des neurones, ce qui génère des lésions en forme de plaques, d’où le nom de la maladie. Cette destruction entraîne des symptômes variés : fatigue, troubles moteurs, sensoriels, cognitifs, sphinctériens ou visuels.

La maladie peut évoluer par poussées (on parle alors de forme rémittente récurrente, qui représente 85 % des cas au début de la maladie) ou de manière progressive.

Historiquement, la sclérose en plaques est considérée comme résultant d’interactions complexes entre le système immunitaire et le système nerveux. Étant une maladie multifactorielle, elle est le résultat de la conjonction entre une prédisposition génétique individuelle et des facteurs environnementaux, comme le virus d’Epstein-Barr (responsable de la mononucléose), une carence de vitamine D, l’obésité, la consommation de tabac ainsi que l’inflammation intestinale. Ces dernières années, un intérêt majeur a été porté sur la contribution de l’intestin au développement de cette maladie.

Le microbiote, régulateur de l’immunité

L’intestin humain abrite plus de 100 000 milliards de bactéries réparties sur une surface de 250 à 400 mètres carrés, soit jusqu’à 10 fois plus que toutes les cellules qui constituent notre corps. Ces microbes assument plusieurs fonctions. Entre autres, ils :

  • protègent l’intestin contre les infections ;

  • aident à digérer certains aliments ;

  • produisent vitamines et molécules utiles (vitamine K, vitamines du groupe B, acides gras à chaîne courte…) ;

  • régulent le système immunitaire.

Le microbiote intestinal interagit par exemple avec les lymphocytes, des cellules qui jouent un rôle central dans l’immunité. Certains profils de bactéries promeuvent la maturation de lymphocytes favorisant l’inflammation (tels que les lymphocytes T helper 17), tandis que d’autres induisent une tolérance immunologique (en promouvant l’expansion de lymphocytes T régulateurs).

Ces interactions permettent de limiter les réactions auto-immunes (des réactions au cours desquelles le système immunitaire s’attaque au corps qu’il est censé défendre) et de protéger le cerveau.

Le microbiote intestinal module aussi l’activité de la microglie, des astrocytes et des oligodendrocytes, des familles de cellules qui jouent un rôle clé dans la défense et la réparation du cerveau.

Déséquilibre du microbiote et sclérose en plaques

Chez les patients atteints de sclérose en plaques (SEP), dans sa forme rémittente ou progressive, le microbiote est déséquilibré. On parle de « dysbiose ». On constate en particulier une diminution des populations de bactéries bénéfiques (Firmicutes, Bifidobacterium, Coprococcus, Roseburia…) et une augmentation des bactéries pro-inflammatoires (Bacteroidetes, Akkermansia, Ruminococcus…).

Cette dysbiose entraîne une baisse de la production d’acides gras à chaîne courte. Or, ces molécules sont essentielles pour équilibrer les divers sous-types de lymphocytes du système immunitaire. En effet, certains acides gras à chaîne courte produits par le microbiote traversent la barrière sanguine et atteignent le système nerveux central. Là, ils limitent l’inflammation en favorisant les lymphocytes T régulateurs et en freinant les lymphocytes T helper 17, responsables de la production de cytokines pro-inflammatoires. Ils contribuent ainsi à l’intégrité de la barrière de protection du cerveau.

Ces métabolites sont également importants pour le bon développement et le bon fonctionnement des cellules qui fabriquent la myéline (les oligodendrocytes nécessaires à la réparation de la gaine qui entoure les neurones). Une étude récente a montré qu’en cas de déséquilibre dans ces molécules, la différentiation et la maturation des cellules productrices de myéline sont bloquées, ce qui empêche donc la remyélinisation.

Certains métabolites régulent aussi l’activité de cellules « support » du cerveau essentielles à son bon fonctionnement (les astrocytes et la microglie). Ce faisant, ils réduisent la production de molécules inflammatoires et limitent les dégâts neuronaux.

À l’inverse, certaines molécules produites par des bactéries pro-inflammatoires accélèrent la destruction de la myéline et perpétuent l’inflammation chronique.

Des recherches ont aussi montré que la composition du microbiote a un impact sur la régulation du rythme circadien, l’horloge interne du corps. Les patients possédant un microbiote plus diversifié ont souvent un meilleur sommeil. Par ailleurs, la bonne régulation de cette horloge interne et la restructuration des rythmes immunologiques et métaboliques pourraient contribuer à contrecarrer la progression de la maladie.

En définitive, l’intestin agit donc comme un véritable chef d’orchestre, modulant immunité, inflammation et réparation nerveuse, et influençant la sévérité et l’évolution de la sclérose en plaques.

Alimentation : régime méditerranéen et vitamine D

L’alimentation façonne le microbiote et l’état inflammatoire de l’organisme. Adopter un régime méditerranéen – riche en fruits, légumes, légumineuses, céréales complètes, poissons, huiles végétales et pauvre en graisses saturées –, anti-inflammatoire, est bénéfique pour les personnes souffrant de sclérose en plaques.

Cette alimentation apporte en effet des fibres et des antioxydants qui nourrissent les « bonnes » bactéries et favorisent la production d’acides gras à courte chaîne, limitant l’inflammation et apportant un soutien aux cellules remyélinisantes. Ce type de régime est associé à moins de fatigue, une meilleure qualité de vie et une possible réduction des poussées.

La vitamine D complète ces effets : elle régule les lymphocytes T, limite l’inflammation et ralentit l’activité de la maladie. À ce sujet, l’étude française « D Lay MS » a montré qu’une supplémentation à haute dose de vitamine D diminue l’apparition de nouvelles lésions et prolonge le temps avant réapparition des symptômes de la sclérose en plaques, tout en restant bien tolérée.

Alimentation et vitamine D constituent donc des leviers concrets pour agir sur le microbiote, l’équilibre immunitaire et la réparation du système nerveux central dans le contexte de la sclérose en plaques. À ces interventions s’ajoutent en outre diverses pistes thérapeutiques basées sur la modulation du microbiote.

L’évaluation des bénéfices potentiels de la modulation du microbiote en complément aux traitements classiques de la sclérose en plaques font notamment l’objet de divers travaux. À titre d’exemple, la supplémentation en propionate (500 mg deux fois par jour) a été associée à moins de poussées et à une stabilisation du handicap.

Au-delà de la restauration du microbiote via l’alimentation, des approches comme l’emploi de prébiotiques, de probiotiques ou la restauration du microbiote sont aussi étudiées. Son impact direct sur la stimulation de la remyélinisation est actuellement étudié.

Des effets qui jouent aussi sur la qualité de vie

Le microbiote influence le quotidien des patients, en jouant sur leur niveau de fatigue, sur leur sommeil, sur leur digestion et sur leur récupération après les poussées. En consultation, nous discutons systématiquement de ce sujet dès le diagnostic de la maladie afin de fournir une prise en charge globale aux patients. Parmi les conseils pratiques à retenir :

  • adopter une alimentation riche en fibres et proche du modèle méditerranéen ;

  • baisser la consommation des aliments pro-inflammatoires, autrement dit les aliments riches en graisses saturées d’origine animale, très transformés, très sucrés ou très pimentés : charcuterie, fromages, crèmes… ;

  • maintenir un sommeil régulier et pratiquer une activité physique adaptée ;

  • limiter le stress et éviter le tabac ou l’excès d’alcool.

Certes, ces mesures ne remplacent pas les traitements médicaux, mais elles améliorent le bien-être, rééquilibrent l’immunité et peuvent contribuer à ralentir la progression de la maladie.

En définitive, un faisceau croissant d’indices montre qu’en matière de sclérose en plaques, intestin et cerveau sont étroitement liés. Favoriser l’installation et le maintien d’un microbiote diversifié permet de moduler l’inflammation, la survie des cellules productrices de myéline et le bon équilibre du système immunitaire, tout en ayant une influence positive sur le sommeil, la récupération et l’énergie quotidienne disponible.

Cette approche, intégrée aux traitements classiques, constitue pour les cliniciens un moyen de ralentir la progression de la maladie, de diminuer les handicaps qui en résultent, et d’améliorer la qualité de vie des patients atteints de sclérose en plaques.
