Fears about TikTok’s policy changes point to a deeper problem in the tech industry

A little over a year after TikTok temporarily went dark in the United States and users were greeted with a message explaining that “a law banning TikTok has been enacted,” those same U.S. users opened the app to find a pop-up message requiring them to agree to new terms before they could continue scrolling.

The new terms of service and privacy policy went into effect on Jan. 22, 2026, following the app’s sale from ByteDance to TikTok USDS Joint Venture LLC, a majority American-owned company that reportedly will control U.S. users’ data and content and the app’s recommendation algorithm.

People see this kind of pop-up all the time, and according to research, the “biggest lie on the internet” is that people ever read anything before clicking “agree.” But given many users’ unease about the ownership change – including fears of swapping Chinese surveillance for U.S. surveillance – it is unsurprising that this time, people paid attention. Screenshots of legal language spread quickly online, accompanied by warnings about sweeping new data collection.

I’m both a TikTok content creator and a tech ethics and policy researcher who has studied website terms and conditions, especially whether people read them (they don’t) and how well they understand them (they also don’t). When I saw the outrage on social media, I immediately dove down a terms of service and privacy policy rabbit hole that had me tumbling into the wayback machine and also looking at similar policies on other apps and TikTok’s policies in other countries.

In the end, I discovered that in the most widely shared examples, the language that sounded most alarming had either hardly changed at all or described practices that are fairly standard across social media.

Some changes aren’t really changes

Consider the list of “sensitive personal information” in TikTok’s new privacy policy, which includes items like sexual orientation and immigration status. Many users interpreted this list as evidence that TikTok had begun collecting more personal data. However, this exact same list appeared in the previous version of TikTok’s U.S. privacy policy, which was last updated in August 2024. And in both cases, the language focuses on “information you disclose” – for example, in your content or in responses to user surveys.

This language is in place presumably to comply with state privacy laws such as California’s Consumer Privacy Act, which includes requirements for disclosure of the collection of certain categories of information. TikTok’s new policy specifically cited the California law. Meta’s privacy policy lists very similar categories, and this language overall tends to signal regulatory compliance by disclosing existing data collection rather than additional surveillance.

Location tracking also prompted concerns. The new policy states that TikTok may “collect precise location data, depending on your settings.” This is a change, but it’s also common practice for the major social media apps.

The change also brings the company’s U.S. policy in line with TikTok policies in other countries. For example, the company’s European Economic Area privacy policy has very similar language, and users in the U.K. have to grant precise location access to use a “Nearby Feed” for finding events and businesses near them.

Though apps have other ways to approximate location, such as IP address, a user will have to grant permission through their phone’s location services in order for TikTok to access precise location via GPS – permission that TikTok has not yet requested from U.S. users. However, the new policy opens the door for users having the option to grant that permission in the future.

This CBC report describes the aftermath of the TikTok sale and why many users are deleting the app.

No news does not equal good news

None of this is to say that users are wrong to be cautious. Even if TikTok’s legal language around data privacy is standard for the industry, who controls your data and your feed is still very relevant. Uninstalls for the app spiked 130% in the days following the change, with many users expressing concern about the ties that the new owners have to President Donald Trump – notably Oracle, the company led by Trump supporter Larry Ellison.

It also didn’t help that TikTok’s first week under American ownership was a complete disaster. Severe technical problems – later attributed by TikTok to a data center power failure – happened to coincide with the new ownership announcement, fueling widespread concerns about censorship of content critical of the U.S. government. Perhaps some users remembered that Trump once joked about making the platform “100% MAGA.”

But regardless of what actually happened, at this point distrusting tech companies isn’t exactly irrational.

Clarity and trust

Conflating very real structural risks with unfamiliar sentences in legal documents, however, can obscure what is actually changing and what isn’t. The misleading information about TikTok’s policy changes that spread across social media is also evidence of a well-known design failure: Most tech policies aren’t made to be read.

My own work revealed that these documents are often written at a college or even graduate school reading level. Another analysis once calculated that if every American read the privacy policy for each website they visit for just a year, it would cost US$785 billion in lost leisure and productivity time.

So the discussion about TikTok’s policies is a case study in the deep mismatch between how tech companies communicate and how people interpret risk, particularly in an era of exceptionally low trust in both Big Tech and government. Right now, ambiguity doesn’t feel neutral. It feels threatening.

Instead of dismissing these reactions as overblown, I believe that companies should recognize that if a huge portion of their user base assumes the worst, that’s not a reading comprehension problem; it’s a trust problem. So writing data privacy policies more legibly is a start, but rebuilding any kind of inherent trust in the stewardship of that data is probably the more important challenge.

Aldi is coming to Colorado, and the disruption could lead to lower food prices

Source: The Conversation – USA (2) – By Jack Buffington, Associate Professor of Practice in Supply Chain Management, University of Denver

Grocery prices have risen by 25% in Colorado over the past five years, more than wages have grown over that same period.

One of the top issues facing Americans is the cost of living relative to housing, health care and food, according to a Reuters/Ipsos survey from December 2025.

Food prices are a more acute problem in Colorado than in many U.S. states due to a highly concentrated retail and supply chain system. King Soopers, which is part of Kroger, and Walmart control nearly half of the total market share. Safeway/Albertsons is losing market share and closing stores, Costco and Sam’s Club are limited, members-only warehouses, and the remaining stores are niche providers and small independents.

Other than raising concerns about food prices with politicians, consumers can’t do much to address this kitchen table topic.

But food shoppers in Colorado are about to get a new option. Grocery store giant Aldi announced that 50 stores and a distribution center will be built in the state over the next five years.

Opportunity for market disruption

It’s true that Aldi’s 50 stores will barely make a dent in a state with well over 1,000 places to buy groceries. But when entering a market, Aldi doesn’t try to compete head-to-head against the giants. Nationwide, it controls just 3% of market share versus Walmart’s 21% and Kroger’s 9%. Instead, Aldi enters a market as a lowest-cost retailer, something that is desperately needed in Colorado.

I spent 20 years in the food industry and research the supply chain.

From my experience, I’ve seen retailers consolidate their market share by lowering prices – only to raise those prices again once the competition has gone out of business. Quite possibly, Aldi’s supply chain strategy is the greatest opportunity to disrupt the stagnation in Colorado’s food market and create positive change for consumers.

Competition in Colorado

Making Colorado’s grocery market more competitive isn’t as simple as adding new stores. There’s a chicken-and-egg, no pun intended, conundrum between retailers and the food supply chain, leading to a lack of healthy market competition.

Colorado isn’t a particularly attractive market for food supply chains because it lies in the sparsely populated and remote Mountain West region, and other than beef, it isn’t a significant food producer. The state is largely a food importer. Its vegetables come from California, Arizona and Mexico, processed meats from Nebraska, Kansas and Texas, and packaged foods from the Midwest.

Colorado has a stable retail market through the two largest grocery chains in the U.S. – Kroger and Walmart – but the state does not offer an attractive opportunity for new entrants or even those existing players. Walmart, for example, has a lower market share of 11% in Colorado than its average U.S. share of 21%. These two companies have little incentive to compete by bringing costs down for Colorado’s consumers.

The grocer market was weakened in 2024 in Colorado and other parts of the U.S. due to a failed merger attempt between Kroger and Safeway/Albertsons. The merger, blocked by a federal court, left these companies in a no-man’s-land in the American food system: not large or efficient enough to compete against Walmart, and not nimble and focused enough to compete against the new upstarts, such as Trader Joe’s and Aldi.

Aldi to upset the market

Nontraditional supermarkets, such as Walmart and Aldi, pose an existential threat to the traditional American supermarket. Nontraditional supermarkets hold 63% of U.S. market share versus 37% for traditional.

It is becoming increasingly difficult for the traditional American supermarket, such as King Soopers, to compete with nontraditional stores that operate on razor-thin margins, pay higher wages and operate massive stores that offer a huge selection of offerings, such as 100 kinds of salad dressing.

In the face of the new realities of higher food costs, I believe that only Walmart can survive in this supercenter model. The alternative is a trend toward smaller, more nimble stores with lower costs and a smaller number of products.

9News Denver reports on Aldi’s plans to come to Colorado.

Aldi’s arrival in Colorado may be the necessary catalyst for disruption. It has the lowest costs – and the lowest profit margins – of any grocery retailer in the U.S. Aldi mainly operates relatively small stores, which means it has lower overhead and sells fewer products than many of its competitors. The key to its low-cost strategy is that nearly all of its product lines are private label. They are produced by a manufacturer and sold under Aldi’s brand name, lowering marketing costs.

Aldi announced plans to build a distribution center in Aurora, Colorado, by 2029. The new center will join ones owned by Walmart and Kroger, creating a more robust, local food supply chain infrastructure that is necessary for lower food prices.

Supply chain innovation coming to Colorado

Americans spend 10% of their income on food, one of the lowest rates worldwide, but many feel like they are becoming less able to afford the groceries they need.

In Colorado, food insecurity affects 1 in 8 people. Rural areas of the state and pockets within cities have become food deserts where the largest supermarkets choose not to enter.

Aldi’s smaller stores, private label products and Colorado-based supply chain system could have a ripple effect on retailers in low-income areas where Dollar Tree and regional independents currently dominate. A stronger emphasis on nimble and efficient food supply chains in places with many supermarkets will inevitably spill into underserved communities with very few or none at all. It’s even possible that this could improve food affordability and accessibility across the state.

Has globalization lessened the importance of physical distance? For economic shocks, new research suggests ‘yes’

Source: The Conversation – USA (2) – By Josh Ederington, Professor of Economics, Miami University

National economies are increasingly moving in sync and responding to the same booms and busts as a result of near-instantaneous communications and interdependent global supply chains. This is a sharp change from much of the 21st century, when economies were primarily affected by economic shocks in neighboring countries.

That’s what we found in a paper published in the journal Economic Letters, in which we calculated measures of economic correlation using data on gross domestic product for 70 countries over the past 60 years. Along with fellow economic scholars Yoonseon Han and David Lindequist, we found that physical distance was indeed less important than it used to be, particularly with regard to how interconnected countries are to one another.

Specifically, we measured the extent to which countries have found their business cycles — the traditional boom-bust intervals of economic performance — in sync. For example, when there is a positive shock to production in Germany, to what extent does this affect incomes in the United States?

We were interested in whether the relationship between distance and economic correlation has changed over time.

What we found was that from 1960-1999, business cycles were strongly localized. That is, a country’s economy was much more likely to be impacted by shocks to nearby countries than by shocks in faraway countries. For example, the U.S. was more affected by economic conditions in Canada or Mexico than it was to economic conditions in the United Kingdom or South Korea.

This finding is not surprising and fits well with a long economic literature showing that countries are more likely to trade with nearby countries and that the volume of trade between two countries is a significant predictor of how synchronized their business cycles are.

However, we went on to find that this relationship between physical distance and economic correlation started to break down after 2000. Specifically, for the past 20 years, there has been no statistically significant relationship between the geographic distance between two countries and the extent to which incomes in the two countries move together — what economists refer to as their economic covariance.

Why it matters

In the late 1990s and early 2000s, a number of economists, including Frances Cairncross and Thomas Friedman, popularized the idea that new technologies like the internet and containerization had led to the death of distance, in which our new lives would be increasingly globalized. They imagined a future in which these new technologies not only impacted how goods were produced — like global supply chains — but also how we work and live.

Such theories were met with some skepticism by trade researchers at the time, and not all of the predictions have come true. For example, the link between distance and trade flows has proved stubbornly persistent. Even today, the top-two trading partners of the U.S. remain Canada and Mexico. And one only has to look at housing prices in major urban centers in the U.S. to see that physical location remains highly valued to most people.

However, our research suggests that at least some of the popular predictions about the globalized economy might be coming true. For instance, the world economy appears to have made countries increasingly susceptible to global, as opposed to localized, shocks.

This was made devastatingly clear to millions of people during the pandemic, when supply chain bottlenecks reverberated across the globe, subsequently generating a worldwide rise in prices. As a result, U.S. economic and trade policy discussions have been increasingly focused on potential vulnerabilities to foreign shocks. Indeed, a new buzzword during the Biden administration was “supply chain resiliance.”

What still isn’t known

Our work provides evidence that business cycles and economic shocks have become more globalized over the past couple of decades. Many of the main economic events from 1960-2000 – like the 1980s savings and loan crisis or the 1997 Asian currency crisis – had primarily localized effects. But more recently, the principal economic events of the past two decades — like the 2008 financial crisis — have had far more global implications.

What we don’t know is whether this pattern will continue, resulting in a new era in which most of the world’s economies move in tandem. Or will a new turn toward economic nationalism lead to a reversal in which economies – and economic shocks – become more localized once again?

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

Will a ‘Trump slump’ continue to hit US tourism in 2026 − and even keep World Cup fans away?

Source: The Conversation – USA (2) – By Frédéric Dimanche, Professor and former Director (2015-2025), Ted Rogers School of Hospitality and Tourism Management, Toronto Metropolitan University

With an upcoming FIFA World Cup being staged across the nation, 2026 was supposed to be a bumper year for tourism to the United States, driven in part by hordes of arriving soccer fans.

And yet, the U.S. tourism industry is worried. While the rest of the world saw a travel bump in 2025, with global international arrivals up 4%, the U.S. saw a downturn. The number of foreign tourists who came to the United States fell by 5.4% during the year – a sharper decline than the one experienced in 2017-18, the last time, outside the height of the COVID-19 pandemic, that the industry was gripped by fears of a travel slump.

Policy stances from the Trump administration on everything from immigration to tariffs, along with currency swings and stricter border controls, have seemingly proved a turnoff to travelers from other countries, especially Canadians – the single largest source of foreign tourists for the United States. Canadian travel to the U.S. fell by close to 30% in 2025. But it is not just visitors from Canada who are choosing to avoid the United States. Travel from Australia, India and Western Europe, among others, has also shrunk.

We are experts in tourism. And while we don’t possess a crystal ball, we believe that the tourism decline of 2025 could well continue through 2026. The evidence appears clear: Washington’s ongoing policies are putting off would-be travelers. In other words, the tourism industry is in the midst of a “Trump slump.”

Fewer Canadians heading south

The impact of Donald Trump’s policies are perhaps most pronounced when looking north of the U.S. border. According to the U.S. Travel Association, Canadian visitors generated approximately 20.4 million visits and roughly US$20.5 billion in visitor spending in 2024, supporting about 140,000 American jobs.

The economic impact of fewer Canadian visitors in 2025 affects mostly border states that depend heavily on people driving across the border for retail, restaurants, casinos and short-stay hotels.

The sharp drop in return trips by car to Canada is a direct indication that border economies might be facing stress. This has led elected officials and tourism professionals to woo Canadians in recent months, sometimes with “Canadian-only deals.”

And it isn’t just border states. In Las Vegas, some hotels are now offering currency rate parity between Canadian and U.S. dollars for rooms and gambling vouchers in a bid to attract customers.

Winter-sun states, such as Florida, Arizona and California, are facing both fewer short-stay arrivals and an emerging drop-off in Canadian “snowbirds.” Reports indicate a noticeable increase in Canadians listing U.S. properties in Florida and Arizona for sale and canceling seasonal plans, threatening lodging, health care spending and property tax revenue.

Economic and safety concerns

Economic policies pursued by the Trump administration appear to be among the main reasons visitors are staying away from the U.S. Multiple tariff announcements – pushing tariffs to the highest levels since 1935 – along with tougher border-related rhetoric and an aggressive foreign policy have contributed to a negative perception of the U.S. among would-be tourists.

Many foreigners report feeling unwelcome or uncertain about travel to the U.S., and some public leaders from Canada and Europe have urged citizens to spend domestically, instead. This significantly reduced intent to travel to the U.S. in 2025.

Meanwhile, exchange rates and inflation have further affected some aspiring travelers, especially Canadians. The Canadian dollar was weakened in 2025, making U.S. trips more expensive. This disproportionately affected day-trip and shopping-driven border crossings.

Travelers are also staying away from the U.S. because of safety concerns. Several countries have posted travel advisories about the risks of traveling to the U.S., with Germany being the latest. Although most worries are related to increased border controls, recent aggressive tactics by immigration agents have added to potential visitors’ decisions to avoid the U.S.

A wake-up call for the US

The current tourism outlook is reason for concern. Julia Simpson, president and CEO of the industry association World Travel and Tourism Council, has described the situation as a “wake-up call” for the U.S. government.

“The world’s biggest travel and tourism economy is heading in the wrong direction,” she said in May 2025. “While other nations are rolling out the welcome mat, the U.S. government is putting up the ‘closed’ sign.”

According to estimates, the U.S. stood to lose about $30 billion in international tourism in 2025 as travelers chose to travel elsewhere.

The disappointing figures for U.S. tourism follow a longer trend. The share of global international travel heading to the U.S. fell from 8.4% in 1996 to 4.9% in 2024 and was expected to drop to 4.8% in 2025. Meanwhile, arrivals to other top tourism destinations, including France, Greece, Mexico and Italy, are set to increase.

The decline is also being felt by the business tourism sector, with every major global region sending fewer people to the U.S. for work.

A World Cup bump?

So what does that mean for the upcoming FIFA World Cup, with 75% of the soccer matches being hosted across the United States? Traditionally, host nations benefit from sports events, although impacts are often overestimated. After a disappointing year, the U.S. tourism sector expects the World Cup to boost visits and revenue.

But Trump’s foreign policy may undermine those expectations.

A new visa integrity fee of $250 and plans for social media screening of some visitors make travel to the U.S. less attractive. And there are growing calls for a boycott of the U.S. following some of Trump’s policies, including his aggressive stance about Greenland.

Former FIFA President Sepp Blatter has suggested that fans avoid going to the U.S. for the World Cup.

It remains to be seen whether fans will follow his call. Bookings for flights and hotels were up after the dates and venues of games were announced in December.

But current political rhetoric is affecting travel decisions, especially given that fans from some specific countries may not be able to get visas. The U.S. government has imposed travel bans on Senegal, Ivory Coast, Iran and Haiti, all of which have qualified for the World Cup.

European soccer leaders have even discussed the possibility of a boycott, although such an action is unlikely to happen, given the revenue at stake for national teams and football associations.

Will the ‘Trump slump’ continue?

White House policies look unlikely to drastically change in the next few months. And this causes concern for tourism professionals, although most have remained silent about the recent immigration crackdown.

To make matters worse, federal funding for Brand USA, the national destination marketing organization, was cut deeply in mid-2025, leading to staff shortages that have reduced the country’s capacity to counter negative sentiment through positive promotion.

Soccer fans tend to be passionate about following their national side. And this could offset some of the impact of the Trump travel slump.

Yet, with sky-high match ticket prices and the international reputation of the U.S. as a tourism destination damaged, we believe it is unlikely that the tourism industry will recover in 2026. It will take a long time and good strategies to repair the serious damage done to the nation’s image among travelers in the rest of the world.

Whether it’s yoga, rock climbing or Dungeons & Dragons, taking leisure to a high level can be good for your well-being

Source: The Conversation – USA (3) – By Emily Messina, Associate Professor of Rehabilitation and Recreational Therapy, Florida International University

What do collecting old editions of Dungeons & Dragons monster manuals, securing the same tailgate spot for over 20 years and mastering yoga postures have in common? They are all forms of “serious leisure.”

These pursuits are different from casual hobbies in several ways. They require participation over longer periods, which makes people who practice them more skilled and more connected with the activity over time. The driving force for casual leisure is having fun; when a participant becomes more focused on accomplishment and improving their skills, the pursuit can gradually become more serious.

I direct the Rehabilitation and Recreational Therapy Program at Florida International University. In my research, I study leisure pursuits and various contexts for serious leisure, with a focus on the tabletop role-playing game Dungeons & Dragons.

I also work in recreational therapy, which helps people recover and return to their pursuits after injury or illness. The approach we use can work as well for someone starting out with a new hobby.

The idea of serious leisure was coined in 1982 by sociologist Robert Stebbins, who described the unique characteristics of more structured leisure pursuits. The more we understand about why people do the things they do, the more they can benefit from their pursuits. Even fringe or supposedly nerdy activities like D&D offer insight into the connections people form when they delve into a nonwork activity.

Executive coach Joe Casey explains the difference between casual leisure and serious leisure.

Why so serious?

People often associate leisure with ease and freedom. In contrast, serious leisure involves pursuing something for a long time and gradually developing the skills and knowledge required to excel at it. People have to push through barriers or setbacks to stay engaged and make progress.

Over time, participants come to identify with the activity and to feel included in a subculture that has its own norms and values. In my work, that sometimes means developing elaborate characters who can battle beasts, dragons and giants.

Dungeons & Dragons, which was developed in 1974, is a long-form game that takes place in multiple sessions that can last weeks, months or years. A Dungeon Master moderates the game and assumes the role of all monsters and non-player characters.

The Dungeon Master narrates an adventure, aided by a Dungeon Master’s Guide and Monster Manual. Players create characters that possess certain traits and qualities. The outcomes of battles, decisions and interactions are determined by dice rolls.

My study included convening focus groups with regular D&D players to determine whether their experiences playing the game represented serious leisure, as opposed to casual leisure associated with traditional board games.

Players described developing their characters for years and acquiring knowledge and skills. They learned how magical items and weapons worked, made calculations and researched their character sheets. All of these practices are attributes of a uniquely D&D subculture.

Participants also described the benefits they received from playing the game. For many of them, D&D offered a sense of community. It also was a safe space and a welcoming activity for those who might feel excluded by traditional leisure pursuits, such as sports and competitive games.

From yoga to tailgating

Prior studies have identified many other activities that can qualify as serious leisure, depending on the level of engagement. Some are in-person physical activities like yoga, sport clubs and rock climbing. Others include online pursuits like multiplayer online games and a virtual Harry Potter running club where members share running stories and experiences keyed to Harry Potter-themed discussion topics, such as logging miles in virtual races for their specific Hogwarts houses. Studies have explored game-based pursuits like tournament bridge, and even the social art of tailgating among serious football fans.

In each case, researchers found that participants experienced hallmarks of serious leisure. For example, participants in multiplayer online games describe prolonged immersion in the activity. Yoga students pursued systematic training and skill development. And maniacally devoted Florida Gators fans scheduled family events around football season.

In all cases, participants became increasingly involved over time, acquired knowledge and skills, and often forged shared identities and social connections.

Joining a run club to master a challenging distance shows how serious leisure can foster social connections and a sense of belonging.

Are you serious?

How do you know if your favorite leisure pursuit has gotten serious? One indication could be spending a lot of time on it and expanding your related knowledge or skills. You may also personally identify with the activity and its associated norms or subculture. Perhaps you’re increasingly spending time with other participants, and even using shared lingo.

Ideally, your serious leisure pursuit will give you pride and a sense of accomplishment. Belonging to a shared subculture can make it easier to express yourself, which promotes social interaction and a feeling of belonging.

These benefits aren’t trivial. Studies show that Americans’ social networks are getting smaller and that people are spending more time alone. These trends are associated with increased risks for premature death, heart disease and stroke, anxiety and depression, and dementia. In 2023, U.S. Surgeon General Vivek Murthy issued an advisory on the loneliness epidemic that called for a national strategy to advance social connection.

Leisure pursuits are a way to develop shared interests and social contacts. For example, dedicated bridge players describe a social world unique to champion-level players that involves hierarchies and relationships spanning decades. Serious participants in multiplayer online games describe feeling like part of a team and working together to share materials, skills and knowledge to help win challenges and battles. And serious football fans describe rites of passage associated with fandom, such as a solo performance of the team fight song on the tailgate of a truck.

How to start

Serious leisure doesn’t happen instantly, and not every practice needs to reach this level of commitment. Casual leisure has benefits too, so there is value in just getting started. But when a beginner gets obsessed with a new pursuit, it may start to take on the qualities of serious leisure over time.

Starting a new hobby can be nerve-racking, especially when it takes place outside of our familiar home environments. Start small, go easy and match the level of challenge with your skill. You just may find yourself getting serious about it.

US experiencing largest measles outbreak since 2000 – 5 essential reads on the risks, what to do and what’s coming next

Source: The Conversation – USA (3) – By Alla Katsnelson, Associate Health Editor, The Conversation

The measles outbreak in South Carolina reached 876 cases on Feb. 3, 2026. That number surpasses the 2025 outbreak in Texas and hits the unfortunate milestone of being the largest outbreak in the U.S. since 2000, when the disease was declared eliminated here.

The outbreak is exposing the breadth of dangers the disease can pose. South Carolina’s state epidemiologist revealed on Feb. 4 that cases of brain swelling, a rare complication of the disease, had emerged in some infected children, according to Wired magazine.

Some signs suggest that this particular outbreak may be starting to wane. But many public health scholars worry that the resurgence of measles across the U.S. and worldwide, driven by a drop in vaccination rates, may signal a coming wave of other vaccine-preventable diseases

The Conversation U.S. compiled a set of five stories from our archives to help readers gauge both practical considerations around vaccination and the bigger picture of what the return of measles might mean for public health.

1. A measles vaccine primer

Measles is one of the most contagious human diseases on the planet – much more contagious than more familiar infectious illnesses such as flu, COVID-19 and chickenpox. But the vaccine, which is given as a two-dose regimen, is 97% effective in preventing measles infection, wrote Daniel Pastula, a neurologist and medical epidemiologist at the University of Colorado Anschutz Medical Campus.

Most people born after 1957 have received the vaccine as children. A striking – though unsurprising – feature of the South Carolina outbreak is that at least 800 of the reported cases occurred in people who weren’t vaccinated.

For those worried about the risks and wondering how to protect themselves, Pastula offered some essential practical guidance.

“The immunity from a vaccine is effectively the same immunity you get from having measles itself – but vastly safer than encountering the wild virus unprotected,” Pastula explained. “The point of vaccines is to create immunity without the risks of severe infection. It is basically a dress rehearsal for the real thing.”

2. Long-term consequences

Most people who contract measles will experience 10-14 days of a high fever, cold-like symptoms, eye inflammation and a rash that starts on the face and spreads across the body. Because the infection usually resolves on its own, it’s easy to dismiss the fact that it can have severe consequences.

“What generally lands people with measles in the hospital is the disease’s effects on the lungs,” wrote Peter Kasson, a biologist studying viruses at the Georgia Institute of Technology, in an article explaining the near- and long-term risks of infection.

Perhaps the most terrifying is a condition called subacute sclerosing panencephalitis, or SSPE, in which the virus lies dormant in the brain of someone who recovered from a measles infection and reawakens 7-10 years later to cause “a progressive dementia that is almost always fatal,” Kasson wrote.

This outcome is rare, but it does happen. The Los Angeles County public health department reported a case in September 2025.

3. What’s at stake

A common adage in public health is that vaccines are often victims of their own success. That’s particularly true for the measles vaccine – because it’s so effective, many doctors and nurses practicing today have never seen a case.

Infectious disease pediatrician Rebecca Schein at Michigan State University explored recent modeling studies that predict the trajectory of measles infection rates. One 2025 study she described found that the U.S. is on track to see 850,000 cases over the next 25 years at current vaccination rates.

“If vaccine rates decrease further, the study found, case numbers could increase to 11 million over the next 25 years,” she wrote.

That scenario is not a foregone conclusion, of course. Another study suggested that outbreaks could be contained if they’re stopped quickly – as long as 85% of the population is vaccinated against the disease.

4. Why do some parents opt out of vaccines?

Much ink, digital and otherwise, has been spilled discussing the rise of vaccine hesitancy in the U.S. and globally. But a safe assumption is that parents the world over want the same thing: to keep their children as healthy as possible.

To explain how parents might reasonably weigh the risks posed by vaccines and the risks posed by a disease like measles and decide not to vaccinate, public policy expert Y. Tony Yang and health economist Avi Dor at George Washington University invoked a mathematical framework called “game theory”.

“Game theory reveals that vaccine hesitancy is not a moral failure, but simply the predictable outcome of a system in which individual and collective incentives aren’t properly aligned,” they wrote.

5. Measles-free status

Measles is said to be eliminated from a country after at least 12 months in which there’s minimal spread of the disease internally and only small outbreaks linked to international travel.

The World Health Organization announced on Jan. 26 that the U.K. and five other European countries lost their measles elimination status, according to Reuters. And the organization’s Pan American office issued an alert on Feb. 3, noting the alarming spread of the disease across North, Central and South America.

In November 2025, when Canada lost its measles elimination status, global health epidemiologist Kathryn H. Jacobsen at the University of Richmond noted that the U.S. will likely lose it in 2026, along with Mexico.

Jacobsen explained why this designation is so important for public health.

“The loss of measles elimination status is a symptom of a deeper issue: declining trust in public messaging about science and health, which has led to decreased vaccination rates and growing vulnerability to vaccine-preventable diseases,” she wrote.

Federal and state authorities are taking a 2-pronged approach to make it harder to get an abortion

Source: The Conversation – USA (3) – By Naomi Cahn, Professor of Law, University of Virginia

The quest to restrict Planned Parenthood’s funding has made headway. Bill Clark/CQ-Roll Call, Inc via Getty Images

Anti-abortion conservatives have long sought to force Planned Parenthood’s clinics to close their doors and to make it harder, if not impossible, to get abortion pills as part of a two-pronged approach to limit access to abortion.

First, undermine Planned Parenthood and other abortion providers by questioning their credibility and block their funding. Second, try to ban mifepristone – a drug used in more than half of all abortions – in part by saying it’s unsafe.

As law professors who teach courses about health, poverty and reproductive rights law, we’re closely watching what’s happening with both strategies. We are particularly interested in how they will affect women’s health care, now that each state can write its own abortion laws.

Attacking Planned Parenthood

Opponents of abortion rights are attacking Planned Parenthood because its clinics perform hundreds of thousands of abortions, in addition to more than 9 million other procedures, every year.

For example, it screens patients for cancer, provides contraceptive care, tests people for sexually transmitted infections, conducts pregnancy tests and offers prenatal services. Abortions account for only 4% of all of Planned Parenthood’s services.

Conservative-led states are taking aim at the nonprofit with both litigation and legislation.

For example, the attorneys general of Missouri and Florida allege in 2025 lawsuits that Planned Parenthood’s website “lies” about the safety of mifepristone.

Planned Parenthood is not the only nonprofit that is accused of deceiving the public that way. In December 2025, the South Dakota attorney general sued Mayday Health, a reproductive health education nonprofit, alleging that its advertising in South Dakota violated a state law that bans “deceptive practices.”

In late January, after Mayday countersued in a federal court in New York, that court temporarily blocked South Dakota’s actions.

Other states are taking similar steps. Kentucky, which, like South Dakota, has a nearly complete ban on abortion, is investigating the legality of ads that Mayday Health posts at gas stations. The ads tell women how they can get help obtaining an abortion.

Undermining funding

Meanwhile, state and federal efforts to reduce Planned Parenthood’s funding are making headway.

In June 2025, the U.S. Supreme Court ruled in Medina v. Planned Parenthood South Atlantic in favor of South Carolina’s attempt to bar its Medicaid program from reimbursing Planned Parenthood for health care services. That decision made it clear that any state may deny Medicaid funding for care provided by organizations, such as Planned Parenthood, that perform abortions.

Medicaid, the U.S. government’s health insurance program that primarily covers low-income people, is jointly funded by federal and state governments. About 1 in 10 women of reproductive age who received family planning services and are enrolled in Medicaid relied on Planned Parenthood’s services in 2021.
EG: Is it more accurate to say “… who in 2021 received family planning services and WERE enrolled in Medicaid relied on Planned Parenthood’s services”?

Under what’s known as the Hyde Amendment, federal Medicaid dollars may not be used to pay for abortions except in cases of life endangerment, rape or incest. States are free to use their own Medicaid dollars to pay for abortions, and some do so.

Shortly after the Supreme Court ruling, Congress passed a measure prohibiting federal Medicaid dollars from going to any clinics that perform abortions – such as Planned Parenthood.

The provision, which bars reimbursement for all services, including those unrelated to abortion, was in the big tax-and-spending package that President Donald Trump signed into law on July 4, 2025. The defunding measure went into effect immediately, for one year, and applies to the whole country.

The provision is supposed to end in July 2026.

Due in part to the financial pressure that measure caused, Planned Parenthood says that dozens of its clinics around the country closed in 2025.

Planned Parenthood, as well as 22 states and Washington, D.C., challenged this provision in two lawsuits in a Massachusetts federal court.

The court granted Planned Parenthood’s request to dismiss its case in January 2026. The other case, brought by the states and Washington, D.C.’s local government, is still pending.

Trying to discredit mifepristone’s safety

Efforts to designate mifepristone as a dangerous drug began before the Food and Drug Administration approved its use in 2000. Abortion opponents have stepped up that campaign since the Supreme Court overturned Roe v. Wade with its Dobbs v. Jackson Women’s Health Organization ruling in 2022.

That same year, a group of doctors and medical associations opposed to abortion challenged the FDA’s approval of mifepristone and the guidelines governing its prescription.

In essence, they claimed that there was insufficient evidence demonstrating the drug’s safety, although it has been used by millions of people for more than 20 years. Several prominent medical associations, citing hundreds of peer-reviewed clinical studies and decades of evidence-based research, assert that the drug is “conclusively safe.”

Many studies have found that mifepristone is as safe as ibuprofen and safer than Viagra.

Ultimately, the Supreme Court rejected the lawsuit because the doctors did not have standing. That is, the physicians couldn’t show that they faced any clear and concrete harms from the FDA’s actions making mifepristone more widely available.

Arguing that the FDA made a mistake

But in 2024, the Missouri, Kansas and Idaho state governments were allowed to join the lawsuit, after they argued that they had standing.

The three states similarly claimed that the FDA acted improperly in 2016 as well as later, when it loosened the regulations around mifepristone, including allowing it to be prescribed via telehealth or mailed to patients.

While their case works its way through the courts, other states are questioning the FDA’s treatment of the drug.

In late 2024, Louisiana classified abortion pills as controlled substances, restricting their use more tightly than the FDA. In October 2025, the state went further, challenging the FDA’s loosened regulations, including its elimination of requirements that the pill be dispensed in person.

And in early December, Florida and Texas sued the FDA. Those states argue that its approval and regulation of mifepristone violated several federal laws, including one that gives the FDA authority to regulate drugs.

Revisiting safety findings

There are also regulatory threats to mifepristone’s availability because the Trump administration is reconsidering evidence regarding the drug’s safety.

In September 2025, Health and Human Services Secretary Robert F. Kennedy Jr. said the FDA would conduct “its own review of the evidence,” including the drug’s “real-world outcomes and evidence, relating to the safety and efficacy.”

Kennedy referenced a report cited by 22 Republican state attorneys general that, according to Kennedy, indicates “potential dangers that may attend offering mifepristone without sufficient medical support or supervision.”

The report has not been peer-reviewed or published in a medical journal. Many experts describe it as “junk science.”

If the FDA were to find mifepristone unsafe or to further restrict how it’s prescribed, this could make it harder to get an abortion. While misoprostol, which is commonly prescribed for ulcer prevention, can be used alone for abortions, it is less effective and less safe than when it’s used in combination with mifepristone.

What happens next might take a while. Some efforts to end access to mifepristone appear to be on hold – for political rather than legal reasons.

FDA Commissioner Marty Makary told the officials working in his agency in December 2025 to delay their review of data concerning the safety of mifepristone “until after the midterm elections” in November 2026.

CAN 2025 de football : pourquoi la CAF a sévi contre le Sénégal et le Maroc

Source: The Conversation – in French – By Professeur Abdoulaye Sakho, Professeur de droit, Université Cheikh Anta Diop de Dakar

La finale de la Coupe d’Afrique des nations (CAN) 2025 (21 décembre – 18 janvier) a basculé dans la la controverse dans les dernières minutes du match. Le penalty litigieux, le match interrompu, l’envahissement de la zone VAR (contrôle vidéo), l’usage de lasers dans les tribunes et les affrontements entre supporters sénégalais et policiers marocains ont marqué l’épilogue du tournoi. Quelques jours plus tard, les sanctions tombent sont tombées contre les fédérations du Sénégal et du Maroc.

Dans cet entretien, Abdoulaye Sakho, spécialiste en droit du sport, décrypte les infractions retenues, le fonctionnement indépendant du jury disciplinaire et pourquoi cette finale pourrait marquer un tournant dans la gouvernance du football africain.

Pourquoi les deux fédérations du Sénégal et du Maroc ont-elles été sanctionnées ?

Les deux fédérations ont été sanctionnées parce que le jury disciplinaire a estimé que chacune d’elles a été coupable d’infractions aux lois du jeu et au code disciplinaire en vigueur.

Le football, en tant qu’activité sportive, repose sur un ensemble de normes qui encadrent à la fois l’organisation des acteurs et leurs comportements sur et en dehors du terrain. Ces normes sont définies par des textes communs à toutes les organisations affiliées à la FIFA,

C’est en ce sens qu’il existe des textes de base qui sont communs à la totalité des organisations sportives qui relèvent de la FIFA. Parmi ces textes, je peux citer le code disciplinaire, le code éthique et le code électoral. Ces textes précisent non seulement les comportements attendus, mais aussi la nature des infractions, les sanctions applicables et le fonctionnement des instances chargées de trancher les litiges disciplinaires.

S’agissant des mesures prises contre les deux fédérations et les joueurs, elles relèvent de sanctions disciplinaires rendues par le jury compétent conformément au code de discipline.

Le comportement des acteurs du football lors d’une rencontre est également défini par les Lois du jeu de l’International Football Association Board (IFAB)
(l’organisme international chargé de définir et faire évoluer les règles du jeu), ainsi que par le code de discipline. Ces deux textes prévoient les infractions et les sanctions, ainsi que l’organisation et le fonctionnement des autorités responsables du règlement des litiges.

Concernant les infractions disciplinaires, comme toutes les autorités juridictionnelles de la Confédération africaine de football (CAF), le jury qui en traite est indépendant. Il est composé de personnalités indépendantes qui ne sont pas membres de la CAF.

Quelles sont les principales sanctions ?

Les deux fédérations ont été sanctionnées parce que le jury disciplinaire a estimé qu’elles étaient responsables d’infractions aux lois du jeu et au code disciplinaire en vigueur. La décision du jury disciplinaire comporte deux volets. Il y a d’abord des sanctions sportives à l’encontre des fédérations marocaine et sénégalaise, et de certains joueurs et officiels pour violations avérées du Code disciplinaire de la CAF. Ensuite, il y a le rejet de la réclamation introduite par la fédération royale marocaine de football (FRMF) qui plaidait un forfait technique du Sénégal. Autrement dit, selon la prétention marocaine devant le jury, fondée les articles 82 et 84 du règlement de la CAN le Sénégal devait perdre le match sur un score de trois à zéro (3-0).

Cette distinction est importante. Le rejet de la requête du Maroc constitue une qualification non retenue, distincte des faits qui ont servi de base aux sanctions retenues contre le Sénégal.

Pour le Sénégal, les sanctions reposent sur les infractions suivantes :

• comportement antisportif, violation des principes de fair-play et d’intégrité, et atteinte à l’image du football ;

• comportement antisportif envers l’arbitre ;

• comportement inapproprié de supporters ayant porté atteinte à l’image du football ;

• comportement antisportif des joueurs et de l’encadrement technique en violation des principes de fair-play, de loyauté et d’intégrité ;

• faute disciplinaire de l’équipe nationale, cinq joueurs ayant reçu des avertissements.

Ainsi, le sélectionneur Pape Bouna Thiaw a écopé d’une suspension de cinq matchs et d’une amende de 100 000 de dollars. Les joueurs Ilimane Ndiaye et Ismaïla Sarr sont suspendus deux matchs pour comportement antisportif envers l’arbitre. La FSF est en outre sanctionnée par trois amendes totalisant 615 000 USD pour le comportement de ses supporters, de ses joueurs, de l’encadrement technique et pour une faute disciplinaire collective liée aux avertissements reçus.

Du coté marocain, les sanctions reposent sur :

• des comportement antisportifs ;

• des comportements inappropriés des ramasseurs de balles du stade ;

• des comportement inappropriés des joueurs de l’équipe nationale et de l’encadrement technique, ayant envahi la zone d’examen de la VAR et entravé le travail de l’arbitre, en violation des articles 82 et 83 du Code disciplinaire de la CAF ;

• l’utilisation de lasers par ses supporters lors du match.

Par conséquent, Achraf Hakimi est suspendu deux matchs, dont un avec sursis, et Ismaël Saibari trois matchs, assortis d’une amende de 100 000 USD pour ce dernier. La FRMF est condamnée à 315 000 de dollars d’amendes pour le comportement des ramasseurs de balles, l’intrusion de joueurs et de membres du staff dans la zone VAR, et l’usage de lasers par des supporters.

Ces sanctions sont-elles en cohérence avec les décisions habituelles de la CAF et auront-elles des effets concrets ?

En matière disciplinaire, chaque situation présente des spécificités qui rendent délicate toute comparaison avec des décisions antérieures. Il faut aussi rappeler qu’il ne s’agit pas d’une décision de la CAF en tant que telle, mais de l’exercice du pouvoir juridictionnel souverain d’un jury indépendant et de la sensibilité de celui-ci aux objectifs généralement attendus des sanctions juridiques. En droit, des sanctions jouent une triple fonction : punition des coupables, réparation des dommages causés aux victimes et dissuasion pour toute autre personne qui serait tentée de refaire la même infraction.

À cette étape de la procédure, il n’est pas aisé de se prononcer d’un point de vue scientifique. À mon avis, il appartient aux concernés, en fonction de leur perception de la réglementation, d’apprécier si ces sanctions sont ou non en phase avec ce que fait d’habitude le jury, si ces sanctions sont ou non « justes » à leurs yeux.

Par ailleurs, le dispositif disciplinaire prévoit le double degré de juridiction. Les parties sont donc libres de voir ou non si elles doivent aller en appel vers la commission de recours, une commission elle aussi indépendante, composée de personnalités indépendantes. La procédure peut même être poursuivie jusqu’au Tribunal arbitral du sport (TAS). D’ailleurs la fédération marocaine a déjà fait appel.

Quelles conséquences ces sanctions pourraient-elles avoir sur l’avenir des compétitions africaines ?

Il s’agit de sanctions que certains ont considérées comme sévères pendant que d’autres ont dit qu’il s’agit de compromis politique. Au-delà des sanctions, c’est le déroulement de cette CAN, le film de la finale et de son dénouement qui pourraient avoir des répercussions sur le futur du football africain et sur la gouvernance de la CAF. La CAN a révélé une absence de lisibilité de l’information où les récits diffusés sur les réseaux sociaux ont pris le pas sur ceux des journalistes.

Qu’on le veuille ou non quelque chose s’est produit en mondovision relativement à la gestion des matchs de football en Afrique.

Des réformes semblent attendues. Le président de la CAF, Patrice Motsepe, a annoncé plusieurs réformes visant à renforcer le cadre réglementaire et institutionnel de l’organisation.

Il a évoqué notamment une révision du code disciplinaire pour “garantir que les organes judiciaires de la CAF disposent de pouvoirs suffisants pour infliger des sanctions appropriées et dissuasives”. Il a aussi réitéré son engagement à veiller à ce que “les opérateurs VAR et les commissaires de match soient perçus, respectés et reconnus comme impartiaux, équitables et de niveau mondial.”

En tous les cas, une fois le chapitre débat autour des sanctions et
des recours clôturés, le football africain devrait ouvrir, de manière concertée et inclusive, le débat sur les réformes nécessaires pour préserver l’esprit sportif du jeu que l’Afrique conçoit de plus en plus comme une activité économique porteuse de croissance et de développement.

Sport et luxe : les enjeux de l’élan olympique de Milano-Cortina

Plusieurs marques de luxe sont associées aux Jeux olympiques d’hiver qui débutent vendredi 6 février. Quels sont les enjeux pour ces marques ? Plus généralement, que traduit le lien croissant entre le monde du sport et celui du luxe ?


À l’aube des Jeux olympiques d’hiver de Milano-Cortina 2026, le marché du luxe, en pleine recomposition post-pandémique, cherche un second souffle. Confrontées à la pression des droits de douane américains, à la montée en puissance des marques chinoises locales et à la faiblesse persistante du dollar et du renminbi face à l’euro, les maisons européennes misent sur les sommets enneigés pour renouer avec l’éclat. Au travers de trois exemples du Vieux Continent (Moncler, Loro Piana et Omega), nous analyserons comment ces maisons se sont emparées de l’opportunité clé que constituent ces jeux pour réaffirmer leur positionnement, capitaliser sur leur héritage et attirer de nouvelles communautés. Comment transforment-elles l’engagement client passant d’une logique de possession à une expérience émotionnelle ?

L’héritage comme actif stratégique : le cas Moncler

Le 31 janvier 2026, Moncler a marqué les esprits avec un défilé spectaculaire à Aspen, dévoilant sa collection Moncler Grenoble automne/hiver 2026. La maison, désormais sponsor officiel du Comité olympique brésilien et partenaire technique de la fédération brésilienne des Sports de neige, s’apprête à habiller les athlètes de ce pays lors des cérémonies d’ouverture et de clôture. Ce retour aux Jeux d’hiver, près de soixante ans après ceux de Grenoble, est une plongée dans l’histoire même de la marque.

JO Milan-Cortina 2026 et Alpes 2030 : qui sont les « éléphants blancs » ?


Née à Monestier-de-Clermont, près de Grenoble, l’entreprise Moncler (d’où l’origine du nom Mon-Cler) s’est forgée une réputation grâce à l’excellence technique de ses produits. Après avoir équipé les vainqueurs du K2 en 1954, elle a connu son heure de gloire en 1968, lorsque Jean-Claude Killy, vêtu de ses doudounes, a remporté trois médailles d’or dans la capitale des Alpes. Tombée dans l’oubli, la marque renaît en 2003 sous l’impulsion de Remo Ruffini, qui en fait un symbole du sportswear urbain chic, incarné par la devise « Né dans les montagnes, vivant en ville » (Born in the mountains, lives in the city). Aujourd’hui, Moncler mise sur des ambassadeurs comme Lucas Pinheiro Braathen (skieur brésilien-norvégien) pour incarner cette dualité entre performance et style, tout en célébrant son héritage pour renforcer son authenticité auprès d’une clientèle exigeante.

Moncler s’inscrit dans une démarche de réancrage historique conciliant héritage technique et désirabilité urbaine. Néanmoins certains voient dans cette participation aux jeux un risque d’opportunisme événementiel et de « greenwashing ». En effet, ces jeux sont accusés de contribuer à la fonte de glaciers tout comme le défilé d’Aspen qui avait nécessité l’utilisation massive de canons à neige. Sans parler de son empreinte carbone liée au déplacement d’équipes, de célébrités et d’influenceurs du monde entier. Enfin malgré les reconnaissances obtenues en matière de développement durable, Moncler reste critiqué avec ses doudounes pour son utilisation de duvet d’oie (même si l’entreprise exige de ses fournisseurs les plus hauts standards de qualité et de bien-être animal).

Raffinement et performance : Loro Piana et l’art de la discretion luxe

A Cortina, Loro Piana a inauguré une boutique conçue comme un chalet, un écrin de sérénité à l’esthétique épurée et aux couleurs naturelles qui se fondent avec le nouveau Pantone 2026 11-4201Cloud Dancer, un blanc gris qui semble avoir été créé pour cet environnement entre neige, montagne et nuages. Elle y présente une collection capsule ski dans laquelle on retrouve tous les codes de la maison (couleurs, élégance intemporelle, cachemire, matières exceptionnelles) et propose également des pièces en textile technique, notamment le tissu Techno Bistretch 3L Storm qui stimule la microcirculation et régule la température corporelle grâce à la caféine contenue dans les couches intérieures. Loro Piana mise sur une expérience sensorielle et une communication subtile destinée à séduire une clientèle aisée représentée à « 90 % à 95 % de clients affluents », à savoir des clients disposant de plus de 250 000€ de patrimoine financier comme l’avait précisé Bernard Arnault lors de l’assemblée générale du 17 avril 2025.

Loro Piana crée du désir sans tomber dans l’excès, la discrétion devient un marqueur de luxe absolu. La maison italienne très dépendante de l’approvisionnement en fibres rares (cachemire « baby cachemire », vigogne) devra toutefois veiller à limiter sa croissance afin de toujours garantir une qualité exceptionnelle sans nuire à la survie des espèces animales. Pour cela, la maison d’origine piémontaise doit assurer la traçabilité de ses matières premières et surtout pouvoir préserver la rareté pour conserver sa clientèle fidèle et fortunée.

Précision et exclusivité : Omega, l’art de la mesure et de l’expérience

Léonard de Vinci disait « Les détails font la perfection et la perfection n’est pas un détail. » L’artisan comme l’athlète répète le geste jusqu’à atteindre la perfection. Sans précision, pas de performance ni d’excellence. Tout doit être calibré, millimétré. Omega, chronométreur officiel des Jeux olympiques depuis 1932, incarne cette philosophie. Pour Milano-Cortina, la marque suisse dévoile deux éditions limitées à destination des collectionneurs : la Seamaster 37 mm Milano Cortina 2026 et la Speedmaster 38 Milano Cortina 2026, où la typologie des jeux orne le cadran. Des modèles signature qui suscitent la désirabilité autant par le produit (design, cadran, finition, précision) que par l’émotion qu’elle génère (rareté, caractère historique, esprit des jeux et valeurs de l’olympisme).


De la possession à l’émotion

Mais Omega va plus loin et s’aventure dans l’hospitalité en ouvrant sa première Omega House à Milan au cœur même de la célèbre Galleria Vittorio Emanuele II dans le restaurant Cracco. Avec l’« Omega Café by Cracco », elle offre à ses membres et ambassadeurs l’opportunité de célébrer ensemble les valeurs olympiques. En choisissant ce lieu symbolique dont le chef est également ambassadeur Omega, la maison associe une expérience culinaire à l’identité de marque. Une très belle initiative réservée à un club d’invités triés sur le volet, une communauté de clients épicuriens et amoureux de belles expériences. Une initiative éphémère, aussi exclusive qu’inoubliable. De cette façon, Omega réussit à transformer un partenariat sportif en une plate-forme d’engagement communautaire tout en préservant l’exclusivité.

LVMH 2026.

Reste à savoir si le développement des nouveaux modèles et les investissements marketing permettront de toucher d’autres segments de clientèle. Et enfin, s’ils procureront le retour sur investissement espéré surtout dans un secteur horloger très concurrentiel avec notamment Rolex (perçu comme plus prestigieux) et des marques plus accessibles (Tudor, Grand Seiko), ou encore les smartwatches (Apple Watch) qui captent une partie du marché.

De l’utilitaire à l’hédonique : le luxe, miroir de nos aspirations

Les Jeux olympiques et plus largement le sport à (très) haut niveau offrent aux marques une tribune unique pour transcender la simple fonctionnalité. Les produits, tout en répondant à des exigences techniques, doivent aussi satisfaire une quête de sens et de plaisir – ce que les chercheurs appellent la « valeur hédonique ». Le luxe contemporain ne se contente plus de posséder : il se vit, s’éprouve, se partage.

Milano-Cortina 2026 s’annonce comme un laboratoire d’innovation pour le luxe européen. Des équipements techniques aux collections capsules, en passant par les montres d’exception et les expériences culinaires, les maisons affûtent leurs stratégies pour attirer et fidéliser les communautés prêtes à investir dans leurs passions. L’enjeu ? Aligner héritage et modernité, allier possession et émotion, et surtout, créer de l’émerveillement – non plus seulement par le produit, mais par l’expérience elle-même. 2026 sera-t-elle l’année où le luxe renoue avec l’authenticité, l’émotion et le frisson partagé ?

Dans l’espace, le vieillissement du cœur des astronautes s’accélère

Source: The Conversation – France in French (3) – By Cyril Tordeur, PhD Candidate in Biomedical Sciences and Pharmacy (Space Cardiovascular Physiology), Université Libre de Bruxelles (ULB)

L’astronaute française Sophie Adenot s’entraîne lors d’un vol parabolique destiné à simuler l’état d’impesanteur. Les travaux révèlent que ce dernier entraîne l’atrophie rapide de petits muscles importants pour l’étanchéité des valves cardiaques. ESA – A. Conigli

De nouveaux travaux révèlent que, dans l’espace, certains muscles du cœur sont mis à rude épreuve par l’impesanteur. En quelques mois, cette dernière provoque leur atrophie. Les conséquences de ce processus, qui prend des décennies sur Terre, sur la santé des astronautes restent à évaluer. Point positif : ces résultats pourraient faire avancer notre compréhension de certains mécanismes à l’origine de l’insuffisance de la valve mitrale.


Considérons, d’un côté, un patient de 80 ans, essoufflé au moindre effort, dont le cœur affaibli laisse refluer le sang vers les poumons et, de l’autre, un astronaute âgé de 35 à 45 ans, entraîné, qui revient de six mois à bord de l’ISS, la Station spatiale internationale, et qui semble en parfaite santé. Que peuvent bien avoir en commun ces deux individus ? Plus qu’on ne le pense.

Pour la première fois, nos travaux ont mis en évidence l’existence chez l’humain d’un phénomène jusqu’alors observé uniquement chez l’animal : dans l’espace, certains petits muscles logés au sein des cavités cardiaques s’atrophient, malgré le sport que les astronautes pratiquent tous les jours.

En réalité, la mission de l’astronaute a donc imprimé sa marque sur son cœur. Derrière son apparente forme physique se cachent des modifications cardiaques subtiles qui miment, en accéléré, ce que le vieillissement a provoqué beaucoup plus lentement chez le patient terrestre. La coupable est l’impesanteur, cet état où la pesanteur du corps ne se fait plus ressentir, qui fait flotter ceux qui s’aventurent dans l’espace. Une situation qui pourrait compliquer les futurs voyages interplanétaires.

Le cœur de l’astronaute face à l’impesanteur

Sélectionnés parmi des milliers de candidats et candidates, les astronautes sont des professionnels soumis à des entraînements rigoureux, et suivis médicalement de manière continue. Pourtant, dès qu’ils quittent la Terre, leur système cardiovasculaire entre dans un processus de « déconditionnement ». Autrement dit, sa physiologie et ses caractéristiques physiques se modifient, parce qu’il n’a tout simplement plus besoin de travailler aussi dur.

En effet, en condition d’impesanteur, le cœur n’a plus la nécessité de lutter aussi difficilement pour propulser le sang vers le cerveau. Les fluides corporels se redistribuent vers la tête, le volume sanguin diminue, et le muscle cardiaque, moins sollicité, s’adapte.

Les scientifiques, qui étudient ces phénomènes depuis les premières missions spatiales, ont découvert que cette adaptation n’est pas sans conséquence. Des études antérieures avaient par exemple montré que le cœur pouvait perdre de la masse musculaire après quelques semaines en orbite, et que sa forme devenait plus sphérique.

Il y a plus de trente ans, une étude menée sur des rats avait aussi mis en évidence une diminution de la taille de petits muscles cardiaques très particuliers, les muscles papillaires.

Les muscles papillaires, essentiels, mais peu étudiés

La mission principale du cœur est de faire circuler le sang à travers les poumons et le corps. Pour cela, il est composé de quatre cavités se contractant à un rythme régulier. Des valves jouent le rôle de clapet antiretour et empêchent le sang de circuler dans le mauvais sens.

Pour accomplir leur fonction, elles reçoivent l’aide de petites structures musculaires, qui représentent moins de 10 % de la masse totale du cœur : les muscles papillaires. Ces derniers évitent que, lorsque le cœur se contracte, les valves ne se retournent comme un parapluie par grand vent. C’est d’ailleurs précisément ce qui se passe en cas d’insuffisance mitrale, une pathologie qui touche des millions de personnes – principalement âgées – dans le monde.

En 1992, une étude menée sur des rats avait mis en évidence une diminution de la taille de ces muscles papillaires, après seulement deux semaines dans l’espace. Néanmoins, aucune étude de ce genre n’avait été menée chez l’humain, au cours de vols spatiaux de longue durée.

Pour combler cette lacune, nous avons utilisé l’imagerie par résonance magnétique (IRM) afin de mesurer précisément la masse de ces petits muscles chez des astronautes assignés à des missions spatiales de longue durée (de six à douze mois) à bord de l’ISS. Les mesures avaient lieu dans une période de quarante-cinq à soixante jours avant le décollage et environ une semaine après leur retour sur Terre.

Un risque de perte d’étanchéité de la valve mitrale

Nos résultats ont mis en évidence une réduction moyenne de 14 % de la masse des muscles papillaires après le vol spatial. Cette atrophie sélective, combinée à la sphéricité accrue du cœur observée en impesanteur ainsi qu’à une augmentation de 6 % du diamètre de la valve mitrale (située entre l’oreillette gauche et le ventricule gauche), crée des conditions anatomiques qui pourraient théoriquement favoriser un manque d’étanchéité de ladite valve.

Dans un tel cas de figure, le sang n’est plus expulsé correctement : au lieu de se diriger en direction de l’aorte, une partie reflue vers l’oreillette gauche, dans le sens contraire de la circulation normale. On parle de « régurgitation mitrale ».

En aigu, cette fuite de sang vers l’oreillette gauche et vers les poumons peut provoquer une détresse respiratoire. À long terme, le cœur, contraint de compenser cette insuffisance progressive, se remodèle petit à petit, jusqu’à ne plus être en mesure de maintenir une fonction suffisante : c’est l’insuffisance cardiaque.

Jusqu’à présent, aucune fuite de ce genre n’a été observée dans le cœur des astronautes, principalement parce que cet aspect n’a pas encore été étudié en détail. D’autres travaux devront être menés pour évaluer les potentielles implications cliniques de ce constat en situation spatiale.

Cette nouvelle étude soulève autant de questions qu’elle apporte de réponses. Nous ne savons pas encore si l’atrophie des muscles papillaires est réversible après le retour sur Terre, ni si elle s’aggrave lors de missions plus longues. Nous ignorons également si elle affecte réellement la fonction de la valve mitrale à long terme.

Des protocoles d’imagerie plus spécifiques, consacrés à l’évaluation valvulaire, et des suivis à long terme seront nécessaires pour répondre à ces interrogations, car les régurgitations mitrales peuvent rester asymptomatiques pendant des années avant que des dommages irréversibles ne surviennent.

L’espace, une « machine à voyager dans le temps » physiologique

Cette découverte prend tout son sens quand on la replace dans le contexte du vieillissement terrestre. Sur Terre, l’inactivité physique prolongée et le vieillissement physiologique sont associés à un risque accru d’insuffisance mitrale. Ce processus se déroule sur des années, voire des décennies. En orbite, l’impesanteur compresse ce temps : en six mois, des modifications anatomiques similaires apparaissent.

C’est ce qui fait de l’espace une « machine à voyager dans le temps » physiologique. Les astronautes ne vieillissent pas réellement plus vite, mais leur corps subit des contraintes qui reproduisent certains effets du vieillissement de manière accélérée et réversible. Cette particularité offre aux chercheurs une fenêtre unique pour observer et comprendre des mécanismes qui, sur Terre, se perdent dans la lenteur du temps biologique.

Le parallèle entre espace et vieillissement terrestre s’étend bien au-delà du cœur. Le système musculosquelettique subit lui aussi un déconditionnement rapide en impesanteur : les astronautes peuvent perdre jusqu’à 1 à 2 % de leur masse osseuse par mois dans certaines régions du squelette, un rythme dix fois supérieur à celui de l’ostéoporose terrestre. Leurs muscles des jambes s’atrophient rapidement, faute de devoir supporter le poids du corps.

Les yeux ne sont pas non plus en reste. En impesanteur, les fluides corporels se redistribuent vers la tête, ce qui augmente la pression au sein du crâne et provoque des modifications structurelles du nerf optique et du globe oculaire, un syndrome désormais bien documenté sous le nom de Spaceflight Associated Neuro-Ocular Syndrome (SANS) ou syndrome neuro-oculaire associé aux vols spatiaux).

Par ailleurs, une autre étude a montré que six mois de vol spatial induisent une résistance à l’insuline associée à une rigidification des artères menant le sang vers le cerveau. Un processus qui, sur Terre, se déroule sur des années.

Pour lutter contre ce déconditionnement généralisé dans l’espace, la solution mise en œuvre sur l’ISS est intensive : les astronautes suivent un protocole strict d’environ deux heures et demie d’exercice quotidien, combinant vélo, tapis de course et renforcement musculaire.

Cependant, si ce protocole permet de limiter considérablement la perte de masse musculaire, ainsi que la masse cardiaque totale, il n’empêche malheureusement pas l’atrophie des muscles papillaires. Cette vulnérabilité spécifique pourrait s’expliquer par leur anatomie unique et leur sous-stimulation en contexte spatial.

De l’orbite au lit d’hôpital : un double bénéfice

Ces observations ont une double portée. Pour les agences spatiales, elles soulignent la nécessité de surveiller la fonction valvulaire des astronautes, particulièrement dans la perspective de missions de longue durée vers la Lune ou vers Mars. Si l’atrophie des muscles papillaires s’aggrave avec le temps, elle pourrait théoriquement compromettre l’étanchéité de la valve mitrale et entraîner des fuites cardiaques chez des équipages, loin de toute assistance médicale terrestre.

Elles ont aussi des implications prometteuses en matière de médecine « terrestre » : comprendre comment l’impesanteur provoque l’atrophie des muscles papillaires pourrait aider à identifier les mécanismes qui sous-tendent également leur détérioration liée à l’âge ou à la sédentarité.

Une chose est certaine : l’étude du cœur des astronautes continue d’éclairer notre compréhension des maladies cardiovasculaires terrestres. Chaque mission spatiale est aussi une mission médicale qui profite aux millions de patients cardiaques sur Terre. En regardant vers les étoiles, nous apprenons à mieux soigner ceux qui ont les pieds sur Terre. Un paradoxe de plus dans cette fascinante aventure qu’est l’exploration spatiale.
