Sovereignty over stereotypes: The data behind false Cherokee identity claims in Canada

From writers and academics to politicians and even convicted murderers, why are people who claim to be Cherokee so prominent in Canadian “pretendian” cases?

Although Métis, Mi’kmaq and Abenaki communities are the Nations most often targeted by unsubstantiated and false claims to Indigenous heritage in Canada, the controversies involving Cherokee claimants may surprise many Canadians.

This is not unexpected. In the United States, it’s so common for non-Native people to claim Cherokee heritage that a family history myth has taken root — one so pervasive that even Ancestry.com warns users against it.

The “Cherokee syndrome” is a phenomenon in which someone claims an unverified distant Cherokee ancestor as the sole foundation on which they build a shallow Indigenous identity.

The roots of ‘Cherokee syndrome’

Most discussions of this phenomenon point to a mix of motivations for these heritage claims.

They include the desire for white settler descendants to distance themselves from their heritage’s history of colonial violence, co-opting Indigeneity for personal or political purposes — often to support right-wing white grievance politics — and basic greed for resources and opportunities belonging to Indigenous Peoples.

In all cases vague, essentialist claims to supposed “blood” are asserted as being more important and more “real” than actual Indigenous cultural belonging, verifiable kinship or confirmed political status.

As a globally recognized Indigenous Nation with a long history of intercultural exchange and intermarriage with newcomers, Cherokees feature prominently in these questionable family mythologies more frequently than other Nations, but only because of stereotypes and visibility, not because of actual relations.

This is increasingly reflected in available data, including national census figures in the U.S. and Canada.

A mismatch between identity and reality

The U.S. Census Bureau has tracked Indigenous heritage claims for decades, and Cherokee is overwhelmingly the group identity most commonly appropriated by Americans.

For example, from 1970 to 2020, Cherokee identification on the U.S. census increased by 2,221 per cent — an astonishing rate far exceeding the general population increase of 63 per cent. This can only be attributed to significant changes in self-identification.

In 2020, “Cherokee” was the top-cited Indigenous affiliation in 35 states, although the three federally recognized Cherokee Tribal Nations and reservations are in only two: Oklahoma and North Carolina. In fact, in 2020, there were more than a million additional Americans who self-declared as Cherokee than there were actual Cherokee tribal citizens.

This is true on the local level as well. The Cherokee National Research Center in Tahlequah, Oklahoma, provides extensive genealogical support for those seeking evidence of Cherokee heritage. Of 4,005 total research requests from 2022 to 2024, only 80 people — two per cent — had any confirmed evidence of Cherokee heritage.

Legitimate Cherokee relations aren’t particularly obscure or difficult to trace. Actual Cherokee scholars like me know that we’re one of the best-documented peoples in the world, with an extensive and detailed documentary archive, as well as community genealogists and researchers who can assess relations with high reliability.

Collating available data from national, tribal and institutional sources indicates that only three to seven per cent of people in the U.S. who assert a public Cherokee identity have any verifiable relationship to living or historical Cherokee communities; 93 to 97 per cent of claimants do not.

This troubling pattern repeats in Canadian census figures as well. In the 2021 census, 10,825 people in Canada identified as being Cherokee. Of the three Cherokee Tribal Nations, the Cherokee Nation has the most inclusive citizenship criteria and the most comprehensive records for genealogical confirmation, yet our own official citizenship data show only 145 Cherokee Nation citizens in Canada.

Figures from the Eastern Band of Cherokee Indians (EBCI) and the United Keetoowah Band of Cherokee Indians (UKB) were unavailable, but would likely be 20 to 30 at most, given their significantly smaller base populations. Even accounting for potential EBCI and UKB figures and a small number of verifiable non-citizen descendants, we would find at most about two per cent of people who claimed Cherokee heritage in Canada having any substantiated relationship with actual Cherokees, past or present.

Tellingly, of the 10,825 “Cherokee” respondents, 5,660 — 52 per cent — are Canadians whose families have been in Canada for three or more generations. Entrenched claims to Cherokee heritage therefore run deep in a surprising number of Canadian families — troubling histories that are only just coming to light in an analysis of the impacts of self-Indigenization and pretendianism.

False claims undermine Indigenous sovereignty

Pretendianism is a direct attack on Indigenous sovereignty and the rights of Native Nations to determine their own protocols of citizenship and belonging.

Believing a quaint family story is one thing, but it becomes deception — and even criminal fraud — when used to unethically access Indigenous relationships and resources, and becomes violence when used to attack Indigenous rights and undermine policies meant to improve Indigenous lives.

The arts, politics, and academia are increasingly sites of fierce debate and even chilling litigation as questionable claims to Indigenous heritage come under increasingly scrutiny from communities, activists and researchers.

The number of Canadians who have used such claims in troubling ways is not insubstantial, and neither are their impacts. Long-celebrated Canadian writer Thomas King and the libertarian Alberta premier, Danielle Smith, are prominent “Cherokee” examples, but they are by no means alone. (Incidentally, Smith is also on record claiming “Métis from America’s Midwest” heritage while consistently pandering to reactionary anti-Indigenous attitudes.)

Cherokee sovereignty and Cherokee people experience real harm when the overwhelming majority of people who insist their unsupported claims are genuine have no actual relationship to Cherokees, no familiarity with or understanding of histories, cultures, languages, struggles or hard-fought rights; no investment in our Nation’s well-being, no respect for our Nation’s political sovereignty and legal orders and no care for or commitment to our actual families or relations.

Using unsubstantiated claims to assert a public Cherokee identity not only misrepresents the ongoing reality of legitimate Cherokee experience, but also deforms how Cherokee belonging and sovereignty are understood in the non-Indigenous cultural imagination, as well as in law and politics. And this, like all the poisonous fruits of colonial violence, is harmful to all Indigenous peoples, not just Cherokees.

Cherokee relations are profound, abiding and verifiable realities. They are far from the self-serving extraction fantasies of colonizers and their claimant descendants, regardless of which side of the 49th parallel they call home.

The raccoon raiding your garbage bin might just be solving a puzzle — for the fun of it

Source: The Conversation – Canada – By Hannah Griebling, PhD Candidate in the Department of Forest and Conservation Sciences, Faculty of Forestry and Environmental Stewardship, University of British Columbia

Ever woken up to find that a crafty raccoon has overturned your garbage bin and spread the discarded contents of your life across the street?

Raccoons — sometimes referred to as “trash pandas” — are renowned as excellent innovators and problem-solvers who can often find their way through the trickiest barriers in their search for food.

So how do raccoons adapt their problem-solving strategies as tasks become more difficult? And will they still engage in problem solving even if it doesn’t lead to a food reward? We designed a research experiment to find out.

We were startled to discover that raccoons were intrinsically motivated to solve multiple puzzles within a 20-minute trial, even when finding a solution did not directly lead to an irresistible marshmallow.

Innovative brains, like primates

Raccoons often engage in problem-solving when foraging in human-dominated areas, and have several adaptations that allow them to do this.

First, they have a high number of neurons packed into a relatively small brain. Their neuronal density is more similar to that of primates than other carnivores.

They also have highly dexterous forepaws adapted for foraging in streams, and a generalist diet that allows them to eat nearly everything we throw away.

As researchers, we were curious to discover whether raccoons change their strategies as problems become more difficult. For example, what does a raccoon do if the garbage bin is open, versus if it has a lid or if that lid is locked?

We were also curious whether their problem-solving follows what we call an exploration-exploitation trade-off.

An irresistable marshmallow reward

To explore these questions, we gave raccoons a multi-access puzzle box. These boxes are used in animal cognition research to study problem solving and innovation. They have multiple problems to solve so the animal can access a single food reward.

Typically, researchers give the animal a multi-access box and let the animal solve a puzzle of their choosing to access the reward. Then, the researcher locks that solution and the animal must innovate a new way into the box.

Instead of locking the solutions on the box we asked a simple question: What would happen if we left the box unlocked and let the raccoons freely interact with it? Would they keep going back to the same solution type that they already knew how to use, or would they explore and open new solution types?

Would they open the box once, get their food reward — a single marshmallow — and be done? Or would they keep playing with the box even after the food
reward was gone?

Raccoons solve problems for fun

What the raccoons did was surprising. We expected them to find multiple solutions on the box. We did not expect them to continue looking for solutions after they found the single marshmallow inside the puzzle box.

They seemed to be intrinsically motivated to open multiple solutions within a 20-minute trial, even when solving the puzzle didn’t directly lead to a marshmallow reward.

In fact, the raccoons were discovering multiple solutions on the puzzle box even when the problems got more difficult to solve, and they could see and feel with their forepaws that there wasn’t another marshmallow in the box.

When the going gets tougher

As those problems became more difficult, the raccoons began to quickly hone in on a single solution to keep returning to.

This follows an exploration-exploitation trade off, where it’s more beneficial to exploit a single solution when the problems are more difficult, since solving them takes more time and effort from the raccoon.

Imagine standing on a city street, feeling hungry. You see your favourite restaurant, where you love the food, and you see an interesting new one next door. Where do you choose to eat?

Humans and non-human animals are faced with these decisions all the time: when to “explore” and try a new thing, and when to “exploit” our own knowledge.

If that new restaurant down the street is expensive, you might be less inclined to try it over your favourite dish served at your usual place.

Success in ever-changing cities

This propensity to innovate and problem-solve, even when it doesn’t directly lead to an extrinsic reward like food, might be familiar to most of us. It’s what drives our desire to solve a crossword puzzle or conquer a new video game.

This intrinsic motivation could help raccoons succeed in urban environments. In cities, resources are often changing rapidly — one night a raccoon might get into someone’s garbage, and the next night there’s a brick on top of the garbage bin to try and keep the raccoon out.

The more problems raccoons learn to solve, the more they might be able to access resources in ever-changing cities. Of course, that might annoy some of us, but we can admire raccoons’ ability to thrive alongside us.

Millions are protesting – but boycotts might be key to changing government policies

The organizers of the estimated 3,000 “No Kings” protests, rallies and other events planned for March 28, 2026, say they expect that the protests will be the largest such mass mobilization in U.S. history.

As scholars of peace studies and social movements, we investigate how ordinary people press their governments to change their policies.

An estimated 7 million Americans took part in the 2,100 “No Kings” protests on Oct. 18, 2025, breaking all previous records. But research that we and other scholars have conducted indicates that massive turnouts at protests may not be enough to achieve the goals of a protest movement, such as bringing about changes in government policies.

We believe that protest movements can be more effective when they place more emphasis on boycotts of corporations that support a government’s agenda than on increasing the size and scope of these protests.

That’s because history suggests that boycotts are uniquely suited to expand public participation and reach the scale necessary for political change. Boycotts attract first-time activists with simple “buy this, not that” instructions. They offer easy ways for people to feel heard with little investment of time, money or risk.

Rise of the ‘No Kings’ movement

The “No Kings” movement has been holding nonviolent protests across the U.S. since June 2025 to express mass opposition to the Trump administration’s policies.

Its organizers include a range of nonprofits. They include those supporting civil rights, such as the American Civil Liberties Union; LGBTQ+ rights, like the Human Rights Campaign; progressive political groups, including Indivisible and MoveOn; and unions, such as the American Federation of Teachers.

The protests’ organizers are harnessing growing public opposition to President Donald Trump’s second administration. Gallup’s final presidential poll, for example, conducted in December 2025, found that only about 1 in 3 Americans approved of his performance.

In March 2026, Fox News found that 6 in 10 Americans disapprove of Trump’s immigration enforcement effort, and a CBS poll found that 6 in 10 oppose the U.S. war with Iran.

The “No Kings” movement from the start has objected to harsh federal immigration enforcement tactics, including the rapid growth in the number of immigrants being detained and deported. The March 28 protests will also make the widespread opposition to the costly Iran war more visible.

“No Kings” organizers cite other reasons for their protests, such as the White House’s threats to intervene in elections, health care spending cuts and the cessation of many environmental protections.

Opposition to Trump is spreading

The “No Kings” protests have spread to more parts of the United States than ever before.

Protests have taken place in every state – in large cities like Dallas, Philadelphia and Phoenix, as well as thousands of smaller towns like Corydon, Indiana, and Hamilton, Montana. The protests even drew thousands of people in some GOP strongholds.

Researchers find that only a small part of the population needs to protest, boycott or strike to create strong pressure. If 3.5% of a population participates in nonviolent protests or boycotts, it can lead to policy changes.

In the United States, 3.5% of the population translates to nearly 12 million people. The “No Kings” movement would need to nearly double in size from its October 2025 levels to reach this threshold.

Boycotts could help reach this tipping point.

How boycotts work

Economic boycotts have a long history as a tool of collective protest as people withdraw their labor, purchases or cooperation to pressure powerful institutions.

Boycotts are a form of mass noncooperation that enables more people to resist without taking time off from work, engaging in confrontation or risking arrest. While demonstrations signal dissent, boycotts change incentives for business leaders. When boycotts cause companies to lose customers and profits slump, they can become unexpected allies in public opposition.

For example, after mass protests against federal immigration raids in Minneapolis, many of the biggest corporations operating in the state released an announcement that called on the government to de-escalate to reduce tensions in the area.

Public support for boycotts

Several consumer boycotts are underway in the U.S., with many taking aim at the Trump administration’s policies.

Boycott leaders focus on major companies, such as Target, Walmart, Amazon and Home Depot, that have donated to the White House ballroom construction project and other causes Trump is personally spearheading,

People’s Union USA, a movement seeking to leverage the power of U.S. consumers, organized what it called a nationwide “economic blackout” on Feb. 28. The organizers urged Americans to avoid spending any money for 24 hours to protest corporate influence over U.S. policies. It’s unclear how effective that boycott was.

Where corporate boycotts have worked

In the 1980s, consumer boycotts of white-owned businesses in South Africa reduced profits and drew global attention to the government’s support of apartheid, a discriminatory system that denied rights to the country’s Black majority. As business suffered, white business leaders pressed for reforms, contributing to the end of apartheid and South Africa’s multiracial elections in 1994.

In the U.S., different boycotts from both the right and the left have compelled Target to change its policies in recent years. Right-wing boycotts demanding the removal of LGBTQ+ Pride merchandise in 2023 caused Target to curtail its embrace of diversity practices.

After Trump’s 2025 executive order banning diversity, equity and inclusion programs, Target faced left-wing boycotts for ending its Racial Equity Action and Change program. The company’s sales fell and its stock declined by 33% in the first three quarters of 2025.

In March 2026, boycott leaders declared victory, saying that the boycotts led to Target’s weak financial performance.

Following the growing wave of consumer boycotts, several media companies have also faced pressure from the public.

In September 2025, Disney suspended late night talk show host Jimmy Kimmel, whose program airs on ABC, after Kimmel suggested that right-wing influencer Charlie Kirk was killed by a fellow conservative. The comedian accused Trump supporters of using his death to “score political points.” Disney owns ABC.

Kimmel’s suspension triggered a rapid public backlash. Three million viewers called for a Disney boycott to disrupt the company’s streaming revenue. Facing mounting risks to its reputation and bottom line, Disney reversed course and put Kimmel back on the air. In December 2025, it renewed his contract for the following year.

The episode illustrated how organized consumer pressure can counter attempts at political intimidation when boycott campaigns focus on a company’s core economic interests.

Uncoordinated boycotts can fail

To be sure, many boycotts fail to meet their goals even when they do succeed at raising awareness.

Their economic impact depends on how many people take part, sustained participation, and clear demands. Boycotts lacking adequate coordination and clear aims are likely to fail, especially when different groups target different companies.

The No Kings protests will no doubt continue to reflect mounting public frustration. But to be effective at their goal of reining in many of Trump’s policies and actions, we believe that this vast movement will likely require a larger, focused boycott that can hurt the revenue and reputation of companies that have financially backed the president or provided support for his policies.

More people are watching podcasts – how The Harry Hill Show could signal the backward-looking future of the medium

Source: The Conversation – UK – By James McLean, Lecturer in Media Production, Graphic Design, and Media Studies, University of Hull

Poet John Cooper Clark on The Harry Hill Show vodscarf. The Harry Hill Show

Television has become a very difficult concept to pin down. It’s no longer the box situated in the corner of a family living room. Mobile platforms, online streaming and different modes of delivery have diffused our understanding of television. The concept of a podcast has, so far, undergone much less scrutiny, and yet we are seeing a need for a similar conversation: what is a podcast, not just to audiences, but to creators?

The podcast is becoming trickier to define. Where its roots may have been in radio, its relationship, or convergence, with that murky beast of television is becoming ever more visible.

To watch a podcast would seem like a contradiction. But in the US the video streamer Youtube has become the most popular podcasting platform. Video is reshaping the industry, with significant growth in people watching podcasts on living room devices – where people used to gather to watch traditional TV.

The usual video of a podcast features the host or hosts and whoever else is on the podcast chatting in front of microphones – the visual element is second to the listening experience. However, there are a slew of new podcasts which are taking this uptick in “viewers” seriously and creating material for them as much as for “listeners”, including the The Harry Hill Show.

In the stand-up comedian’s own words, The Harry Hill Show is a “vodscarf” – wordplay on podcast and video-on-demand. What makes this “vodscarf” interesting is the television-podcast format it toys with. While it is one product, the experience of watching the Harry Hill Show is different from just listening to it. It’s not that you’ll miss anything important information wise just listening but the visual experience is not secondary to the audio – as sets and camerawork, including visual gags and effects, are worked in. The show also draws on Hill’s own history in television.

Harry Hill is best known for his sketch show Harry Hill, later titled The All-New Harry Hill Show and also referred to as The Harry Hill Show, which ran from 1997 to 2003. In each episode, Hill delivered his surrealist comedy through a series of regular sketches, reoccurring characters and catchphrases that would repeat week-on-week. Into the 2000s, Hill fronted TV Burp for 11 series. The show infused his tried-and-tested formula into the television-clip show format.

Features from both these shows can be found in his podcast, which is clearly infused with a lot of nostalgia for that bygone era of TV comedy. Hill is mostly deskbound, as he was on TV Burp, and he again finds humour through the repetition of gags (“don’t make that noise, Gary, it will limit your appeal” is repeated weekly to his ventriloquist’s dummy, for instance). The segments have a deliberate (and possibly necessary) low-cost aesthetic, a style common to UK comedies from the broadcast television era of the 1990s like Hill’s shows.

But this isn’t simply a TV show masquerading as a video podcast. The Harry Hill Show also acknowledges and embeds common podcast ingredients. Each week the show has a special comedy guest and an educational guest who are interviewed in a traditional podcast style. Yet all the elements are highly reflexive as Hill passively (and sometimes actively) deconstructs podcasts and TV.

The single-guest interview that is at the centre of The Harry Hill Show, is common to the podcasting tradition. Media academics have noted that this format generates content that thrives on intimacy and authenticity. With Hill, this format is subverted by televisual factors where the guest is continually challenged and wrongfooted by his ludicrous segments.

For instance, in Hill’s Name That Seed segment, the special guest must guess the identity of a particular seed from a pack of 8,000 different species. The game is whimsical and deliberately baffles the guest. Like many comedy podcasts, this and other segments create in-jokes with the audience. The more you’ve listened or watched The Harry Hill Show, the stronger a listener/viewer’s relationship becomes with the podcast and the more they are rewarded. After listening to several episodes, they know how the seed segment goes and can laugh along, on the inside of the joke, with Hill.

In essence, Hill takes the scripted comedy format of his television work and rebuilds it into a podcast medium that prefers unscripted and authentic encounters. In doing so, he has created a recipe that provides audiences with familiarity of TV but with the authenticity and intimacy of podcast.

The Harry Hill Show is an example of a podcast that could reshape the medium by mixing older approaches to modern media. Hill does this by reconstructing his identity and past formats through a podcast that clearly enjoys celebrating their mutual deconstruction (or destruction). As special guest Nish Kumar comments to Hill in the show’s trailer: “You’re self-funding your own nervous breakdown!”

With The Harry Hill Show we’re seeing something that’s not strictly television, but not strictly a podcast either. It is an example of the increasing importance of visuals, which could overtake the importance of audio. But who knows? This could be a flash-in-the-pan moment, or it could signal something deeper for the medium – that the podcast might be a media format with a limited shelf life.

The natural birth movement empowers many women but pressure can also work the other way

Source: The Conversation – UK – By Frances Hand, PhD Candidate, Faculty of Law, University of Oxford

Reshetnikov_art/Shutterstock

Childbirth is often framed as a choice between two extremes: “natural” birth or medical intervention. The real challenge is making sure women can decide how they give birth, without pressure in either direction.

Debates about childbirth often focus on pressure to accept medical interventions in hospital, such as caesareans or forceps delivery. But recent NHS maternity inquiries suggest some women feel pressure in the opposite direction. They describe being discouraged from medical assistance even when they believed it would be safer, or better for them.

One healthcare professional giving evidence in the 2022 Ockenden Review, which examined preventable deaths and injuries affecting mothers and babies between 2000 and 2019, described a culture in which avoiding caesarean sections had become a source of institutional pride:

They were always very proud of their low caesarean rates … I personally found all the failed or attempted instrumental deliveries very difficult to deal with. I had never seen so many injuries … or resuscitations … Nothing to be proud of.

Evidence presented to a House of Commons inquiry into the safety of maternity services similarly found that “hundreds of women felt pressure to have a normal birth”, without medical assistance.

During my doctoral research examining childbirth narratives across several major UK maternity inquiries, I analysed thousands of women’s birth stories submitted to public investigations. Some accounts describe women who felt discouraged from receiving medical assistance even when they would have preferred it.

The natural birth movement – which emerged in the mid-20th century as a reaction against the increasing medicalisation of childbirth – advocates for minimal pain medication, midwife-led care, and avoiding caesarean sections and instrumental deliveries where possible. It was designed to encourage women to reclaim control of their bodies from a medical establishment that had, in many cases, taken that control away.

That impulse was legitimate, and the movement has acted as an important counterweight to routinised, unnecessary intervention. But the same cultural force that pushed back against overmedicalisation can, in some settings, tip into a different kind of pressure – one where accepting medical help feels like failure.

When legal rights meet clinical reality

One of the most influential cases in modern medical law addressed this issue of informed choice during childbirth. In Montgomery v Lanarkshire Health NHS Trust (2015), the doctor did not warn the patient about the risks of vaginal delivery because they believed “it was not in the maternal interests for women to have caesarean sections”.

The Supreme Court rejected this reasoning. Instead, it emphasised that patients must receive clear information about risks and alternatives so they can make their own decisions about treatment.

Current Nice guidelines reinforce this principle. They stress that maternity care should support women’s choices during birth and caution against allowing personal opinions to influence the interventions that are offered.

The UK government also recently abandoned the World Health Organization recommendation that caesarean births should not exceed 20% nationally, after concerns that rigid targets were pressuring NHS Trusts to prioritise statistics over safety.

Despite these safeguards, institutional practices can still shape the choices that women feel able to make.

How pressure can shape birth decisions

Some women say these pressures reflect wider cultural narratives about childbirth. In recent years, messages celebrating “natural”, “empowered” or “positive” birth have become increasingly visible in antenatal classes, books and online communities. While these approaches are often intended to build confidence and support informed choice, some women say they can also create an environment in which accepting medical help feels like a failure, or where women worry they may be judged for being “too posh to push”.

These narratives don’t just circulate in parenting spaces or social media. They are also seen in how hospitals – intentionally or unintentionally – present different birth options to expectant parents.

This can feel particularly significant because it comes from institutions that women expect to trust. It shows how legal protections don’t always translate into everyday clinical practice.

In some cases this influence appears in the language hospitals use to describe different birth options. Recently archived material from one hospital promoted non-medicated birth approaches by stating that “treatments are usually non-invasive and rarely cause the unpleasant or long-lasting side effects that can be associated with medication”.

Language like this is often intended to reassure patients. But it can also shape how different options are perceived, particularly when the potential drawbacks of medical interventions are emphasised more strongly than their benefits.

In other cases, the pressures are structural. Some maternity units are organised in ways that make it difficult to move quickly between midwife-led and obstetric wards. Women have described having to walk between departments while in pain and sometimes partially undressed. Situations like this illustrate how problems can arise not from individual professionals, but from how hospital systems are designed.

Finally, recent research by Birthrights, a UK charity that campaigns to protect women’s rights during pregnancy and childbirth, highlights institutional barriers to maternal request for caesarean sections. The organisation found that 113 NHS Trusts do not fully align with Nice guidance. Some policies delayed decisions until 36 weeks of pregnancy, creating uncertainty for expectant mothers.

Pressure to avoid medical intervention should be taken as seriously as pressure to undergo it. Although more than half of first-time mothers experience some form of obstetric intervention, many report feeling ashamed when this occurs.

This matters because some research has linked birth-related shame with an increased risk of suicidal thoughts among mothers, associated with an expressed sense of failure to birth “normally”. When hospital policies create additional barriers to accessing care, they may reinforce these feelings.

Why the term ‘obstetric violence’ matters

Around the world there is growing recognition of the concept of “obstetric violence”, a term used to describe systemic harms that women may experience during childbirth. The concept highlights how these harms often arise not from malicious individuals but from institutional cultures, clinical norms and wider social expectations about motherhood.

Much of the global discussion about obstetric violence has focused on the dangers of overmedicalisation. However, similar pressures can arise when women feel discouraged from accepting medical interventions. In both situations, expectations about the “ideal” self-sacrificing mother can shape how decisions about birth are framed.

In the UK, the term “obstetric violence” is rarely used in policy or public discussion. This reluctance matters. Without language that clearly names systemic harm, it becomes harder to recognise patterns, challenge institutional norms and push for meaningful change.

Many women have positive experiences of both natural and medically assisted birth, and most maternity professionals work hard to support women’s choices. What matters most is that decisions about birth are based on balanced discussions of risks and benefits.

Recognising how pressure can operate in both directions is essential if maternity care is to genuinely support women’s autonomy during childbirth.

The four types of dementia most people don’t know exist

Source: The Conversation – UK – By Clarissa Giebel, Senior Research Fellow in the Institute of Population Health, NIHR Applied Research Collaboration North West Coast, University of Liverpool

What most people think of when they hear the word “dementia” is memory problems and forgetfulness. But what people often don’t know is that dementia can cause many different symptoms – affecting speech, behaviour, sleep, motor function and more.

In fact, dementia is an umbrella term. There are estimated to be more than 100 types of dementia. Alzheimer’s disease is the most common subtype of dementia, affecting approximately 60% of all cases. Memory loss in one of the most common symptoms of this type of dementia.

But approximately 40% of all dementia cases are considered to be different, rarer types. Unfortunately, having a rarer subtype of dementia often makes diagnosis more difficult and requires more complex care.

Although most people might be aware of some types of dementia – including Lewy Body, Parkinson’s disease dementia and frontotemporal dementia – awareness of other rarer types is low.

Knowing how to spot the signs of these rarer types of dementia early could be crucial in ensuring loved ones get the support they need.

Posterior cortical atrophy

Posterior cortical atrophy (PCA) affects mostly visual and spatial functioning. Memory is not as badly affected early on as it is in Alzheimer’s disease.

People with PCA can struggle with visual hallucinations and spatial navigation. This can become apparent when reading or judging depth and space on a staircase – making it difficult to judge where the next step is, for example. Symptoms commonly start appearing between the ages of 55 and 65.

There’s still much we don’t know about PCA because of how rare it is. Researchers are still trying to figure out whether PCA is a distinct subtype of dementia or whether it’s an atypical form of Alzheimer’s disease. This is because the brain changes that occur in people with PCA closely resemble those that occur in people with Alzheimer’s disease, although the symptoms are different. It’s also estimated that between 5% to 15% of people with Alzheimer’s have PCA.

Creutzfeld-Jakob disease

Creutzfeld-Jakob disease is a particularly rare form of dementia, affecting about one in 1 million people worldwide.

Creutzfeld-Jakob disease is a prion disease. These diseases involve prion proteins which, for unknown reasons, suddenly change into a three-dimensional shape. The function of healthy prions remains unknown, but they appear to play some role in protecting nerves and brain cells and keeping the body’s circadian rhythm functioning (the natural, 24-hour cycle our body follows that controls everything from sleep, digestions and immunity).

The misfolding of prion proteins in Creutzfeld-Jakob disease causes a very rapid and severe form of dementia, progressing much more quickly than Alzheimer’s disease or Lewy Body dementia, for example. Besides the notably quick nature of progression, people with Creutzfeld-Jakob disease struggle with memory and movement, including sudden jerky movements.

Risk factors for this subtype of dementia include old age and genetics (occurring in 10-15% of cases). In very rare cases, it can also develop as a result of contamination – such as from eating beef from cattle infected with mad cow disease.

FTD-MND

FTD-MND is a form of frontotemporal dementia that occurs alongside motor neurone disease.

Frontotemporal dementia refers to subtypes of the disease that cause gradual brain tissue loss in the frontal and temporal lobes of the brain.

Motor neurone disease, on the other hand, is a rapidly progressing neurological condition which can lead to difficulties breathing, movement and paralysis. Although it affects the brain and nerves, it is not itself a form of dementia.

Approximately 10-15% of people with frontotemporal dementia also develop motor neurone disease. This co-occurence seems to be linked to a mutation in the C9orf72 gene. Because of this genetic link, FTD-MND can run in families.

People with FTD-MND experience several muscle-related issues, including muscle waste, stiffness and problems with swallowing. These are things you would not normally associate with dementia and memory problems.

It’s currently not clear whether frontotemporal dementia develops first and then motor neurone disease, or if it’s the other way around.

Progressive supranuclear palsy

Progressive supranuclear palsy (PSP) is a rare neurological condition that causes both dementia and problems with movement.

It’s estimated to affect approximately 4,000 people in the UK. PSP is difficult to diagnosis as it overlaps with many other conditions – including Parkinson’s disease.

PSP primarily leads to damage in subcortical brain regions, specifically the brainstem and basal ganglia. These areas are linked to vision and movement.

As such, people with PSP struggle using their eyes and can thus often fall and experience difficulties moving around. People with PSP can also struggle concentrating and problem solving.

Dementia support

As with all dementia subtypes, there is no cure yet. While there are medications that can delay symptoms, these only work in cases of Alzheimer’s disease.

As such, we still need to find ways to support people with other subtypes of dementia as best as possible.

One way of doing this is by properly understanding their condition and their subtype. Knowing that someone might particularly struggle with walking and movement as opposed to memory is important to put the right care in place in advance.

It is just as important to be able to spot the signs early on. Dementia doesn’t just affect memory. Changes in behaviour, problems seeing or falling more frequently, walking or moving differently or difficulty speaking can all be early signs of dementia.

Better understanding dementia’s many forms will hopefully lead to better ways of managing and treating this complex disease.

Protests coupled with boycotts tend to be most effective at making governments change policies

The organizers of the estimated 3,000 “No Kings” protests, rallies and other events planned for March 28, 2026, say they expect that the protests will be the largest such mass mobilization in U.S. history.

As scholars of peace studies and social movements, we investigate how ordinary people press their governments to change their policies.

An estimated 7 million Americans took part in the 2,100 “No Kings” protests on Oct. 18, 2025, breaking all previous records. But research that we and other scholars have conducted indicates that massive turnouts at protests may not be enough to achieve the goals of a protest movement, such as bringing about changes in government policies.

We believe that protest movements can be more effective when they place more emphasis on boycotts of corporations that support a government’s agenda than on increasing the size and scope of these protests.

That’s because history suggests that boycotts are uniquely suited to expand public participation and reach the scale necessary for political change. Boycotts attract first-time activists with simple “buy this, not that” instructions. They offer easy ways for people to feel heard with little investment of time, money or risk.

Rise of the ‘No Kings’ movement

The “No Kings” movement has been holding nonviolent protests across the U.S. since June 2025 to express mass opposition to the Trump administration’s policies.

Its organizers include a range of nonprofits. They include those supporting civil rights, such as the American Civil Liberties Union; LGBTQ+ rights, like the Human Rights Campaign; progressive political groups, including Indivisible and MoveOn; and unions, such as the American Federation of Teachers.

The protests’ organizers are harnessing growing public opposition to President Donald Trump’s second administration. Gallup’s final presidential poll, for example, conducted in December 2025, found that only about 1 in 3 Americans approved of his performance.

In March 2026, Fox News found that 6 in 10 Americans disapprove of Trump’s immigration enforcement effort, and a CBS poll found that 6 in 10 oppose the U.S. war with Iran.

The “No Kings” movement from the start has objected to harsh federal immigration enforcement tactics, including the rapid growth in the number of immigrants being detained and deported. The March 28 protests will also make the widespread opposition to the costly Iran war more visible.

“No Kings” organizers cite other reasons for their protests, such as the White House’s threats to intervene in elections, health care spending cuts and the cessation of many environmental protections.

Opposition to Trump is spreading

The “No Kings” protests have spread to more parts of the United States than ever before.

Protests have taken place in every state – in large cities like Dallas, Philadelphia and Phoenix, as well as thousands of smaller towns like Corydon, Indiana, and Hamilton, Montana. The protests even drew thousands of people in some GOP strongholds.

Researchers find that only a small part of the population needs to protest, boycott or strike to create strong pressure. If 3.5% of a population participates in nonviolent protests or boycotts, it can lead to policy changes.

In the United States, 3.5% of the population translates to nearly 12 million people. The “No Kings” movement would need to nearly double in size from its October 2025 levels to reach this threshold.

Boycotts could help reach this tipping point.

How boycotts work

Economic boycotts have a long history as a tool of collective protest as people withdraw their labor, purchases or cooperation to pressure powerful institutions.

Boycotts are a form of mass noncooperation that enables more people to resist without taking time off from work, engaging in confrontation or risking arrest. While demonstrations signal dissent, boycotts change incentives for business leaders. When boycotts cause companies to lose customers and profits slump, they can become unexpected allies in public opposition.

For example, after mass protests against federal immigration raids in Minneapolis, many of the biggest corporations operating in the state released an announcement that called on the government to de-escalate to reduce tensions in the area.

Public support for boycotts

Several consumer boycotts are underway in the U.S., with many taking aim at the Trump administration’s policies.

Boycott leaders focus on major companies, such as Target, Walmart, Amazon and Home Depot, that have donated to the White House ballroom construction project and other causes Trump is personally spearheading,

People’s Union USA, a movement seeking to leverage the power of U.S. consumers, organized what it called a nationwide “economic blackout” on Feb. 28. The organizers urged Americans to avoid spending any money for 24 hours to protest corporate influence over U.S. policies. It’s unclear how effective that boycott was.

Where corporate boycotts have worked

In the 1980s, consumer boycotts of white-owned businesses in South Africa reduced profits and drew global attention to the government’s support of apartheid, a discriminatory system that denied rights to the country’s Black majority. As business suffered, white business leaders pressed for reforms, contributing to the end of apartheid and South Africa’s multiracial elections in 1994.

In the U.S., different boycotts from both the right and the left have compelled Target to change its policies in recent years. Right-wing boycotts demanding the removal of LGBTQ+ Pride merchandise in 2023 caused Target to curtail its embrace of diversity practices.

After Trump’s 2025 executive order banning diversity, equity and inclusion programs, Target faced left-wing boycotts for ending its Racial Equity Action and Change program. The company’s sales fell and its stock declined by 33% in the first three quarters of 2025.

In March 2026, boycott leaders declared victory, saying that the boycotts led to Target’s weak financial performance.

Following the growing wave of consumer boycotts, several media companies have also faced pressure from the public.

In September 2025, Disney suspended late night talk show host Jimmy Kimmel, whose program airs on ABC, after Kimmel suggested that right-wing influencer Charlie Kirk was killed by a fellow conservative. The comedian accused Trump supporters of using his death to “score political points.” Disney owns ABC.

Kimmel’s suspension triggered a rapid public backlash. Three million viewers called for a Disney boycott to disrupt the company’s streaming revenue. Facing mounting risks to its reputation and bottom line, Disney reversed course and put Kimmel back on the air. In December 2025, it renewed his contract for the following year.

The episode illustrated how organized consumer pressure can counter attempts at political intimidation when boycott campaigns focus on a company’s core economic interests.

Uncoordinated boycotts can fail

To be sure, many boycotts fail to meet their goals even when they do succeed at raising awareness.

Their economic impact depends on how many people take part, sustained participation, and clear demands. Boycotts lacking adequate coordination and clear aims are likely to fail, especially when different groups target different companies.

The “No Kings: protests will no doubt continue to reflect mounting public frustration. But to be effective at their goal of reining in many of Trump’s policies and actions, we believe that this vast movement will likely require a larger, focused boycott that can hurt the revenue and reputation of companies that have financially backed the president or provided support for his policies.

Why do basketball players miss shots they’ve made a thousand times before? Neuroscience has an answer

Source: The Conversation – USA – By David Van den Heever, Associate Professor of Agricultural and Biological Engineering, Mississippi State University

Every March Madness it happens. A player steps to the line, takes the shot and misses. And just like that, there goes your perfect bracket.

These are elite players. The player has made that shot thousands of times before. So what went wrong this time?

Research from my lab has found that the difference between making and missing a shot may come down to stability not only in how you move but how you think.

Measuring brain activity

My team wanted to understand how people build their skill at shooting hoops. So we examined the early phase of learning this particular skill – when coordination between your brain and body is still being formed rather than taken for granted.

Decades of research on the performance of elite athletes suggest that their sport-specific movements are consistent and their brains appear to be optimized for the task. In other words, they show less unnecessary brain activity and more focused processing on executing a specific activity. But it is not known whether these brain states are exclusive to elite performance or whether they can begin early in the learning process.

To investigate this question, my team recorded both the body movement and brain activity of novice and intermediate basketball players as they shot hoops. Specifically, we used motion capture technology to analyze their movement mechanics and electroencephalography to analyze their neural activity. After a brief practice and familiarization phase, each player took 50 shots. We then compared the shots that went in with those that did not.

What we found was telling.

Successful shots for all players were associated with more consistent movement patterns. The feet and lower body were positioned to provide a stable base of support, improving balance and enabling more effective transfer of force to the ball. Joint motion across the body was more coordinated, and variability was reduced in key segments of the movement, particularly at the wrist and elbow.

At the neural level, successful shots were associated with more stable neural activity. There was also increased activity related to the integration of sensory information and motor control.

Unsuccessful shots, by contrast, were much more inconsistent, showing small fluctuations throughout the movement. This suggests the players were continuously correcting their movements mid-execution. Similarly, brain activity during missed shots appeared to reflect a system still trying to figure things out, continuously evaluating, adjusting and correcting.

This trial-by-trial variability and adjustment is exactly what’s expected in early skill acquisition. According to a classic model of learning, beginners rely more heavily on effortful processing of verbal, visual and spatial information as they learn to coordinate perception and action. In other words, they are consciously and actively thinking through the movement. Learning requires exploration, error detection and correction as the brain and body are searching for a solution.

Even within this messy process of learning, successful attempts already showed signs of greater control. Making a shot was not simply about whether the brain was more or less active, but about how consistently it operated. Successful shots were marked by a more stable, less variable brain state, along with activity patterns suggesting the brain was better tuned to the demands of the task.

Mind over matter

But here’s the catch: The processes that help you learn can hurt you when you perform.

Elite athletes are not consciously micromanaging each action. Rather, they rely on systems that have been finely tuned through repetition. As skill develops, performance becomes less about effort and more about consistency. Variability decreases as neural processing becomes more efficient.

Under pressure, however, that stability is exactly what can break down. A college player may be very talented, but they are still developing physically and mentally. In high-stakes, high-pressure moments – especially like those in March Madness, which they haven’t experienced in practice – pressure can push the athlete back into their own heads. They may begin to monitor and control their movements more consciously and explicitly. This reintroduction of conscious processing can disrupt the automatic coordination they have built through practice, inadvertently increasing the variability of their movements and thoughts and therefore reducing performance.

Training that focuses not only on the mechanics of the sport but also the mental side of performance could help athletes enter, maintain or return to the mental state that supports consistent performance, even under pressure. My lab is investigating biofeedback and neurofeedback tools to help make these invisible states and metrics visible to aid in training. If athletes can learn how their brains and bodies react under pressure and practice returning to a more stable state, that may be one path toward more consistent performance.

The goal is not just to learn the right movement, but also to learn when and how to stop trying to control it.

NASA’s Artemis II mission will take an astronaut crew around the Moon – a space policy expert describes the long road to launch

NASA is once again shooting for the Moon, for the first time since the 1970s. As soon as April 2026, NASA will launch its Artemis II mission, using the Space Launch System heavy lift rocket to send a crewed spacecraft, called Orion, into orbit. From there, the crew will journey to and circle around the Moon over 10 days.

In this episode of The Conversation Weekly podcast, we spoke to Scott Pace, the director of the Space Policy Institute at George Washington University. Pace worked with the George W. Bush administration in space policy, and from 2017 served for four years as the executive secretary of the National Space Council during Donald Trump’s first term as president.

In the first paragraph, it makes it sound like the spacecraft is landing on the moon. “From there, the crew to orbit around the Moon over 10 days”

We’re about to send humans in orbit around the Moon again. What’s had to happen to get to this point?

Pace: Let’s go back to the 1980s and 1990s. After the space shuttle Challenger accident, a lot of people were thinking, “What do we do next?”

The space shuttle program was not an economic success. The recurring cost per flight was very expensive. So there was a lot of thinking about different vehicles that could be the shuttles’ successor. NASA pursued some of the higher-risk options, thinking that if they didn’t work out, they could still extend and use the shuttle. Some of those higher-risk ideas were things like single-stage-to-orbit space planes. When they didn’t work, it was OK because NASA was still working on the shuttle.

And then we had the 2003 space shuttle Columbia accident. NASA figured they could either stop for a decade or so and then try to restart a human spaceflight program once they had better technology, or try to transition the infrastructure and industrial base they had with the space shuttle to a new system.

When the second shuttle accident happened, we examined what we had to build a new system with, and we had solid rocket boosters and external tanks. To make something safer, we needed to build crew capsules. A capsule with an escape system onboard was one of the few immediate ways you could increase the likelihood of a crew’s survival.

If your eventual goal is Mars, you’ll then need a really heavy-lift vehicle to launch more crew and a heavier load. All that deliberation led to the current Space Launch System and the Orion capsule.

Four astronauts will be sent on a 10-day mission orbiting the Moon. What’s exciting to you about this mission, and what will you be looking out for?

Pace: The first thing is the performance of the solid rocket boosters on launch. Boosters are very reliable, but if they go bad, they go bad pretty quickly. The next thing is a checkpoint in Earth’s orbit when they’re going to make a decision about whether to do a translunar injection. During the translunar injection, they fire the engine to escape Earth’s orbit and get on the right path to orbit around the Moon.

Before they decide, they’re going to check the environmental control and life support system to make sure the passengers are safe and healthy inside the vehicle. Once you make the commitment to head for the Moon, that life support system is going to be essential. And they haven’t yet done a full flight test on Orion of the environmental control and life support system.

The translunar injection is actually fairly straightforward. In many ways, this is less risky than Apollo 8, which went to the Moon and then fired its engines to get into a stable orbit around the Moon. Then, it fired the engines again to come home.

Artemis II is more like Apollo 13. They’re going up, looping around the Moon and using its gravity to whip around and then come back. In some ways, it’s a less risky trajectory than Apollo 8 because you don’t have to fire the engines as much.

When the crew vehicle comes back, we’re going to look at its heat shield performance. The heat shield has had a long and complicated history. It looks like it’ll be safe, but this is a flight test. And so we’re going to look at how it reenters the atmosphere and how it handles the heat load put on it.

The SLS does come with challenges. One is the high cost. Every time you build one of these vehicles, it costs several billion dollars. The other problem is flight rate.

Some people will argue that beating China to the Moon is really important. Does that matter to you?

Pace: It matters to me if China is the only one showing up and they drive all the standards and the operating norms on the Moon. But the issue of beating China back in the near term doesn’t quite seize me as much as the longer term.

This is part of the problem I have with the term “race.” The U.S. had a space race in the past, but what we have now with China is a long-term competition.

Space is not yet contentious in the way the South China Sea is, or border disputes with India are. But I can see why some people are worried by looking at China’s behavior in other areas.

Part of the stated goal for Artemis is to secure a lasting presence on the lunar surface. Do you think there’s a rationale for nations to stay permanently on the Moon now?

Pace: Humanity’s future in space depends on two sub-questions. First: Can you live off the land and use local resources, or are you always dependent upon Earth? Second: How are you paying? Are you also financially dependent upon Earth – for example, supported by taxpayers?

If you can both use local resources and do something economically useful, then you can build space settlements and get permanent human activity beyond the Earth.

If the answer is no on both counts, then space is like Mount Everest: It’s a place of adventure and symbolism. People can go there and take pictures. But nobody really lives there.

If you can do something useful in space and generate an economic return, but still have to come home to Earth because the environment can’t support life long term, then space is like a North Sea oil platform. It’s a dangerous and difficult place, but a place where you can go for economic reasons.

If you still have to depend on taxpayer money, space may be similar to Antarctica – like going to McMurdo Station. You can do science there and have a human presence, but it’s a constrained environment.

Part of the purpose of exploration is to find out which of these futures is feasible. Some people have faith that space settlements are possible. But we really don’t know.

If it turns out there are economically useful things to do on the Moon, there may be an eventual transition. Activity on the Moon would go from a government-led effort to one led by private sector activities, including mining helium-3 or shipping water back to refueling stations.

If it turns out that none of that really makes sense, we’d still have some science presence there, but we would press on to Mars. I think there’ll be some sort of scientific presence regardless – but its size will depend on economics and markets that we, frankly, don’t understand yet.

The world today in space is much more globalized, much more democratized. Many more countries and entities are involved in space. While the U.S. wants to be the leader in this effort, it knows that simply doing it with a NASA logo is really not sufficient. The Artemis program is meant as an international and commercial partnership effort with others to voluntarily shape what space looks like.

Scientists may be overestimating the amount of microplastics in the environment – and the culprit is lab gloves

Source: The Conversation – USA – By Anne McNeil, Professor of Chemistry and Macromolecular Science and Engineering, University of Michigan

Gloves used in the laboratory that led to microplastic overestimation. Madeline Clough

It seems like every day a new study finds tiny plastic particles called microplastics where they should not be: in our bodies and our food, water and air.

Yet finding and identifying microplastics is extremely challenging, especially given their small size. One microplastic can range from as large as a ladybug to as small as an eighth of a red blood cell.

In addition, it can be hard for researchers to avoid unintentionally contaminating their samples, because these plastics are practically everywhere. As a result, much of this research may be overestimating the number of microplastics.

In a new study published in March 2026, our team found that, even when following established protocols, using certain methods to measure environmental microplastics can potentially contaminate the results.

Microplastics are tiny plastics shed from plastic waste. They are found in the environment, waterways and even the human body.

The study

We are chemists at the University of Michigan working in a collaborative team. We set out to understand how many microplastics Michiganders were inhaling when outside, and whether that depended on where they lived.

When preparing our samples, we followed all the standard protocols while conducting our research – we avoided plastic use in the lab, wore nonplastic clothing and even used a specialized chamber to reduce potential contamination from the laboratory air.

Despite these precautions, we found plastic counts in the air that were over 1,000 times greater than previous reports. We knew these numbers didn’t seem right, so what happened?

The culprit: Lab gloves

After a long path to pinpointing the contamination source, we found that laboratory gloves, which the scientific community recommends using as a best practice, can transfer particles to the surface of our samples – in this case, small metal sheets used to collect material depositing from the air. Moreover, the particles led to an overestimation of microplastic abundance in our study.

Here’s how: The particles, which we identified as stearate salts, are used to help the gloves cleanly release from their mold during the manufacturing process. When gloves are used to handle laboratory equipment, the particles are transferred to anything they touch. Stearate salts are similar to soap molecules – if you eat a lot of them, they’re probably not good for you, but they’re not harmful in the environment in the same way that microplastics are.

While not microplastics themselves, stearate salts are structurally similar to polyethylene, the type of plastic most often found in the environment. This structural similarity makes it difficult to distinguish them using the most common tools scientists use to determine whether a particle is plastic.

Researchers use vibrational spectroscopy to identify microplastics, which entails measuring how the particle interacts with light to produce what scientists call a chemical fingerprint.

Because polyethylene and stearate salts have very similar structures, they also interact with light in a similar way.

As a result, at least some of the time, the particles from gloves are incorrectly identified as microplastics. As more researchers rely on automated methods to speed up their analyses, glove residue may be increasingly mistaken for microplastics, leading to higher reports of microplastics in the environment than in reality.

How widespread is this contamination?

To investigate how prevalent this contamination might be, we looked at different glove types. We mimicked the touch between seven types of gloves while handling laboratory equipment and counted the number of microplastics we would incorrectly attribute to the environment if we followed the most common approaches.

We found that gloves can contribute over 7,000 particles per square millimeter that are misidentified as microplastics. This finding means that researchers could be unknowingly overestimating microplastic abundance in the environment when handling their samples with gloves.

Even more concerning, we found that the particles were largely less than 5 um in size. Microplastics in this size range have larger impacts on human and ecosystem health because they can more easily enter cells. By inflating microplastic counts in this size range, using laboratory gloves may jeopardize the studies that inform future policies and regulations.

How handling samples with gloved hands leads to an overestimation of plastics.

Moving forward

To avoid contamination, we suggest scientists avoid glove use while conducting microplastic research. If that is not possible – for example, with biological samples where the researchers must wear gloves to protect themselves – we recommend a glove made without stearates, such as those designed for electronics manufacturing. To recover older, potentially contaminated datasets, we have developed methods to help differentiate the chemical fingerprints.

Science is an iterative process. New areas of research, including environmental microplastics, introduce new challenges to the scientific community. In addressing these new challenges, we will encounter setbacks, such as unforeseen contamination.

While we had to discard our initial dataset, we expect the lessons we learned about glove contamination to reach other scientists. In addition, we plan to continue our research on Michigan’s atmospheric microplastic contamination – but this time without gloves.

It’s important to note that even if the microplastic abundance in the environment is lower than researchers originally thought, any amount of microplastics can be troublesome, given their negative effects on human health and ecosystems.
