It’s easy making green: Muppets continue to make a profit 50 years into their run

Source: The Conversation – USA (2) – By Jared Bahir Browsh, Assistant Teaching Professor of Critical Sports Studies, University of Colorado Boulder

A variety show that’s still revered for its absurdist, slapstick humor debuted 50 years ago. It starred an irreverent band of characters made of foam and fleece.

Long after “The Muppet Show”‘s original 120-episode run ended in 1981, the legend and legacy of Miss Piggy, Fozzie Bear, Gonzo and other creations concocted by puppeteer and TV producer Jim Henson have kept on growing. Thanks to the Muppets’ film franchise and the wonders of YouTube, the wacky gang is still delighting, and expanding, its fan base.

As a scholar of popular culture, I believe that the Muppets’ reign, which began in the 1950s, has helped shape global culture, including educational television. Along the way, the puppets and the people who bring them to life have earned billions in revenue.

Johnny Carson interviews Muppet creator Jim Henson, Kermit and other Muppets on the ‘Tonight Show’ in 1975, ahead of one of an early ‘The Muppet Show’ pilot.

Kermit’s origin story

Muppets, a portmanteau of marionette and puppet, first appeared on TV in the Washington, D.C., region in 1955, when Henson created a short sketch show called “Sam and Friends” with his future wife, Jane Nebel.

Their motley cast of puppets, including a lizardlike character named Kermit, sang parody songs and performed comedy sketches.

Henson’s creations were soon popping up in segments on other TV shows, including “Today” and late-night programs. Rowlf the Dog appeared in Canadian dog food commercials before joining “The Jimmy Dean Show” as the host’s sidekick.

After that show ended, Rowlf and Dean performed on the “Ed Sullivan Show,” where Kermit had occasionally appeared since 1961.

Rowlf the Dog and Jimmy Dean reprise their schtick on the ‘Ed Sullivan Show’ in 1967.

From ‘Sesame Street’ to ‘SNL’

As Rowlf and Kermit made the rounds on variety shows, journalist Joan Ganz Cooney and psychologist Lloyd Morrisett were creating a new educational program. They invited Henson to provide a Muppet ensemble for the show.

Henson waived his performance fee to maintain rights over the characters who became the most famous residents of “Sesame Street.” The likes of Oscar the Grouch, Cookie Monster and Big Bird were joined by Kermit who, by the time the show premiered in 1969, was identified as a frog.

When “Sesame Street” became a hit, Henson worried that his Muppets would be typecast as children’s entertainment. Another groundbreaking show, aimed at young adults, offered him a chance to avoid that.

“Saturday Night Live’s” debut on NBC in 1975 – when the show was called “Saturday Night” – included a segment called “The Land of Gorch,” in which Henson’s grotesque creatures drank, smoked and cracked crass jokes.

“The Land of Gorch” segments ended after “Saturday Night Live’s” first season.

‘Saturday Night Live’s’ first season included ‘Land of Gorch’ sketches that starred creatures Jim Henson made to entertain grown-ups.

“The Muppet Show” was years in the making. ABC eventually aired two TV specials in 1974 and 1975 that were meant to be pilots for a U.S.-produced “Muppet Show.”

After no American network picked up his quirky series, Henson partnered with British entertainment entrepreneur Lew Grade to produce a series for ATV, a British network, that featured Kermit and other Muppets. The new ensemble included Fozzie Bear, Animal and Miss Piggy – Muppets originally performed by frequent Henson collaborator Frank Oz.

“The Muppet Show” parodied variety shows on which Henson had appeared. Connections he’d made along the way paid off: Many celebrities he met on those shows’ sets would guest star on “The Muppet Show,” including everyone from Rita Moreno and Lena Horne to Joan Baez and Johnny Cash.

“The Muppet Show,” which was staged and shot at a studio near London, debuted on Sept. 5, 1976, in the U.K, before airing in syndication in the United States on stations like New York’s WCBS.

As the show’s opening and closing theme songs changed over time, they retained a Vaudeville vibe despite the house band’s preference for rock and jazz.

The Muppets hit the big screen

“The Muppet Show” was a hit, amassing a global audience of over 200 million. It won many awards, including a Primetime Emmy for outstanding comedy-variety or music series – for which it beat “Saturday Night Live” – in 1978.

While his TV show was on the air, Henson worked on the franchise’s first film, “The Muppet Movie.” The road film, released in 1979, was another hit: It earned more than US$76 million at the box office.

“The Muppet Movie” garnered two Academy Award nominations for its music, including best song for “Rainbow Connection.” It won a Grammy for best album for children.

The next two films, “The Great Muppet Caper,” which premiered in 1981, and “The Muppets Take Manhattan,” released in 1984, also garnered Oscar nominations for their music.

As ‘The Muppet Movie’ opens, Statler and Waldorf tell a security guard of their heckling plans.

‘Fraggle Rock’ and the Disney deal

The cast of “The Muppet Show” and the three films took a break from Hollywood while Henson focused on “Fraggle Rock,” a TV show for kids that aired from 1983-1987 on HBO.

Like Henson’s other productions, “Fraggle Rock” featured absurdist humor – but its puppets aren’t considered part of the standard Muppets gang. This co-production between Henson, Canadian Broadcast Corporation and British producers was aimed at international markets.

The quickly conglomerating media industry led Henson to consider corporate partnerships to assist with his goal of further expanding the Muppet media universe.

In August 1989, he negotiated a deal with Michael Eisner of Disney who announced at Disney-MGM Studios an agreement in principle to acquire The Muppets, with Henson maintaining ownership of the “Sesame Street” characters.

The announcement also included plans to open Muppet-themed attractions at Disney parks.

But less than a year later, on May 16, 1990, Henson died from a rare and serious bacterial infection. He was 53.

At the end of ‘Fraggle Rock’s’ run, its characters look for new gigs.

Of Muppets and mergers

Henson’s death led to the Disney deal’s collapse. But the company did license The Muppets to Disney, which co-produced “The Muppet Christmas Carol” in 1992 and “Muppet Treasure Island” in 1996 with Jim Henson Productions, which was then run by Jim’s son, Brian Henson.

In 2000, the Henson family sold the Muppet properties to German media company EM.TV & Merchandising AG for $680 million. That company ran into financial trouble soon after, then sold the Sesame Street characters to Sesame Workshop for $180 million in late 2000. The Jim Henson Company bought back the remaining Muppet properties for $84 million in 2003.

In 2004, Disney finally acquired The Muppets and most of the media library associated with the characters.

Disney continued to produce Muppet content, including “The Muppet’s Wizard of Oz” in 2005. Its biggest success came with the 2011 film “The Muppets,” which earned over $165 million at the box office and won the Oscar for best original song “Man or Muppet.”

“Muppets Most Wanted,” released in 2014, earned another $80 million worldwide, bringing total global box office receipts to over $458 million across eight theatrical Muppets movies.

The ‘Muppet Show’ goes on

The Muppets continue to expand their fandom across generations and genres by performing at live concerts and appearing in several series and films.

Through these many hits and occasional bombs, and the Jim Henson Company’s personnel changes, the Muppets have adapted to changes in technology and tastes, making it possible for them to remain relevant to new generations.

That cast of characters made of felt and foam continue to entertain fans of all ages. Although many people remain nostalgic over “The Muppet Show,” two prior efforts to reboot the show proved short-lived.

But when Disney airs its “The Muppet Show” anniversary special on Feb. 4, 2026, maybe more people will get hooked as Disney looks to reboot the series

‘The Muppet Show’ will be back – for at least one episode – on Feb. 4, 2026.

Innovations in asthma care can improve the health of Detroiters living with this chronic disease

Source: The Conversation – USA (3) – By Arjun Mohan, Clinical Associate Professor of Internal Medicine, University of Michigan

Researchers and doctors are beginning to modernize asthma treatment using innovative therapies.

Asthma is a common, chronic and treatable lung disease that touches nearly every family in America. It affects people of all ages and costs our health care system about US$82 billion each year.

In Michigan, the problem is acute. About 12% of Michigan adults live with asthma, compared to almost 9% nationwide, according to the Centers for Disease Control and Prevention.

Nowhere is the burden heavier than in Detroit, which is ranked No. 1 in the U.S. as the most challenging place to live with asthma – based on prevalence, emergency department visits and deaths.

Between 2021 and 2023, the city’s adult asthma rate was 14.8%, compared with 11.5% statewide, according to data from the Michigan Department of Health and Human Services. Childhood asthma reaches nearly 15%, almost double the state average.

Between 2019 and 2023, Detroiters were hospitalized for asthma more often than residents elsewhere in the state. Black residents, women and people with lower incomes bear the greatest burden, facing higher rates of disease and worse outcomes, such as hospitalization.

Personalized care based on medical advances

My experience as an asthma specialist has taught me humility in the face of this complex disease. Over the past decade, I’ve learned the value of pausing and inviting each patient to reflect on their own journey with asthma.

For some, it is a new and confusing diagnosis – often accompanied by a degree of denial about having a chronic condition that needs constant management.

For others, this process gives them space to reflect on disease-related harms such as lifetime exposure to corticosteroids, which treat inflammation, or the number of emergency department visits they have endured.

Taking time to reflect also gives doctors and patients an opportunity to think about other issues affecting the patients’ health. For example, patients often struggle with the relationship between asthma and being overweight. It is hard for them to lose weight due to their symptoms or the side effects of oral steroids.

This mutual understanding becomes the foundation for a personalized care plan, often using the latest scientific advances in therapy. My colleagues and I at the University of Michigan are deeply involved in clinical trials investigating novel therapies and forward-thinking approaches to asthma care.

These approaches are centered in the long-held principle that a preventive and proactive approach to care is better than a reactive one.

The problem with ‘wait-and-see’ care

Decades of research show that asthma, while characterized by airway inflammation and spasming, is a heterogenous syndrome. This means it takes many forms and affects patients in different ways.

For some, asthma fades over time or remains mild and manageable. For others, it is a lifelong struggle, marked by frequent flare-ups, hospital visits, missed days at work or school and declining lung function.

Alarmingly, severe outcomes can happen even in those labeled as having “mild” asthma. A seemingly manageable episode can suddenly become serious, reminding us how easily this disease can be underestimated.

Most people seek help for asthma only when symptoms get bad. They may find themselves overusing a rescue inhaler or needing urgent care or the emergency department. These flare-ups, also called exacerbations, are serious.

Patients who have frequent exacerbations are more likely to have future flare-ups and face long-term risks such as loss of lung function or even death.

Even the medicines used to treat flare-ups carry risks. Just two courses of oral steroids per year can raise the risk of osteoporosis, diabetes or cardiovascular disease. It is also important to note that poorly controlled asthma or regularly needing higher-dosage inhalers can lead to irreversible airway damage and loss of lung function.

Many patients also rely on the emergency department for routine asthma care. This is often due to poor knowledge about asthma, high medication costs, insurance barriers and life constraints such as work or school. Yet emergency departments are not designed for ongoing management. Emergency departments cannot provide lung-function testing, maintenance inhalers, long-term monitoring or follow-up care – all critical to keeping asthma under control.

In other words, the health care field’s current approach is reactive, waiting for symptoms to spiral downward and not really focused on addressing risk. Patients with warning signs often go unnoticed or receive treatments that don’t meet their needs. This approach to care is outdated and poorly suited to modern medicine.

Tailoring interventions to each individual

A better approach starts with awareness of asthma’s variability and moving away from “one-size-fits-all” care.

Consider allergen control. Detroiters are exposed to both year-round allergens – such as dust mites, cockroaches and indoor molds – as well as seasonal allergens such as tree, grass and weed pollens.

Allergen mitigation was once a major strategy for managing asthma and often thought of as a stand-alone intervention. But allergen mitigation alone is rarely enough. For example, if dust mites trigger asthma, using mattress covers alone isn’t sufficient – you also need to wash bedding weekly and avoid heavy humidifiers. The approach should incorporate different methods to reduce exposure.

Meanwhile, allergen control for people without clear sensitivity is often ineffective and expensive. The best care starts with a conversation between patients and a clinician: testing triggers, reviewing evidence-based strategies and tailoring interventions to what will work for each person.

Asthma also often flies under the radar, not just for doctors but for patients too. About 1 in 5 patients underestimate the severity of their asthma, while many overestimate their control. Awareness of red flags – such as frequent flare-ups or poor symptom control – is critical. Daytime symptoms more than twice a week, nighttime symptoms more than twice a month, frequent use of emergency inhalers or limited physical activities all signal risks.

These warning signs can be controlled in nearly 95% of patients with minimal medications, proper inhaler technique, addressing environmental triggers and treating related conditions such as acid reflux.

For 5% to 10% of patients with severe or hard-to-treat asthma, close monitoring and specialist care are essential.

Specialist visits allow a thorough review of a patient’s history, including long-term steroid use, and help identify low-hanging fruit such as poor inhaler technique, lifestyle factors, coexisting conditions or diseases that mimic asthma.

Identifying symptoms early can mitigate health risks

New tools, such as blood tests and breath analyses, can measure airway inflammation and even predict flare-ups, treatment failures or lung function loss. While not yet widely used, these tools are the first giant leap toward proactive care, identifying problems before they take a serious toll. For example, patients with signals of inflammation in both blood and breath tests are at a much higher risk of future loss of lung function and exacerbations than their counterparts without these signals.

Another major advance is targeted therapies called biologics. These shots are usually administered under the skin by patients at home. They help control inflammation caused by asthma. In carefully selected patients, biologics can reduce flare-ups and hospitalizations, improve lung function, enhance quality of life and lower the need for oral steroids.

Many federally sponsored insurance programs now include certain biologics on their list of covered prescription drugs. However, actual approval and patient out-of-pocket costs can vary widely.

Advancing a new vision for asthma care

Michiganders would benefit from raising their awareness of asthma, not just because asthma is common here but because our environment is changing fast. Events like the 2023 Canadian wildfires show that the air we breathe is dynamic and unpredictable.

In my view, it is imperative to adopt a proactive approach that uses commonsense measures, promotes awareness, applies evidence-based practice and identifies at-risk people early. Achieving this vision requires addressing real-world challenges such as research gaps, costs and access to care.

Asthma is not just a personal health issue, it is a public health priority. My patients are impacted not only by lifestyle choices but also by factors outside of their control – factors such as drug costs, insurance plans, environmental changes and access to care.

Should medical marijuana be less stringently regulated? A drug policy expert explains what’s at stake

Source: The Conversation – USA (3) – By Chris Meyers, Adjunct Professor of Philosophy, George Washington University

Reclassifying marijuana to a Schedule III drug would put it in a category with prescription drugs like ketamine. LPETTET/iStock via Getty Images

Medical marijuana could soon be reclassified into a medical category that includes prescription drugs like Tylenol with codeine, ketamine and anabolic steroids.

That’s because in December 2025, President Donald Trump signed an executive order to reschedule marijuana to a less restricted category, continuing a process initiated by President Joe Biden in 2022.

Currently, marijuana is in the most restrictive class, Schedule I, the same category as street drugs like LSD, ecstasy and heroin.

For years, many researchers and medical experts have argued that its current classification is a hindrance to much-needed medical research that would answer many of the pressing questions about its potential for medicinal use.

In January 2026, Republican Senators Ted Budd, of North Carolina, and James Lankford, of Oklahoma, introduced an amendment to funding bills trying to block the rescheduling, claiming that it “sends the wrong message” and will lead to “increased risk of heart attack, stroke, psychotic disorders, addiction and hospitalization.”

As a philosopher and drug policy expert, I am more interested in what is the most reasonable marijuana policy. In other words, is rescheduling the right move?

Broadly speaking, there are three choices available for marijuana regulation. The U.S. could keep the drug in the highly restricted Schedule I category, move it to a less restrictive category or remove it from scheduling altogether, which would end the conflict between state and federal marijuana laws.

As of January 2026, cannabis is legal in 40 of 50 states for medical use and 24 states for recreational use. Rescheduling would only apply to medical use.

Let’s examine the arguments for each option:

Proponents of rescheduling marijuana say that it would be a boon to medical research on the plant, especially in states like Colorado, where there is a thriving medical marijuana industry.

The Controlled Substances Act

The Controlled Substances Act places each prohibited drug into one of five “schedules” based on proven medical use, addictive potential and safety.

Drugs classified as Schedule I – as marijuana has been since 1971, when the Controlled Substances Act was passed – cannot be legally used for medical use or research, though an exception for research can be made with special permission from the Drug Enforcement Administration. Schedule I drugs are believed to have a high potential for abuse, to be extremely addictive and to have “no currently accepted medical use.”

As a Schedule I drug, marijuana has been more tightly controlled than cocaine, methamphetamine, PCP and fentanyl, all of which belong to Schedule II.

The status quo option

Some policy analysts and anti-marijuana activists argue that marijuana should remain a Schedule 1 drug.

A common objection to rescheduling it is the assertion that 1 in 3 marijuana users develop an addiction to the drug, which stems from a large study called a meta-analysis.

A careful reading of that study reveals the flaws in its conclusions. The researchers found that about one-third of heavy users – meaning those who use marijuana weekly or daily – suffered from dependence. But when they looked at marijuana users more generally – meaning people who tried it at least once, the way addiction rates are normally measured – they found that only 13% of users develop a dependency on marijuana, which makes it less habit-forming than most recreational drugs, including alcohol, nicotine and caffeine, none of which are scheduled under the Controlled Substances Act.

Further, if the 1-in-3 figure were accurate, then marijuana would be more addictive than alcohol, crack cocaine and even heroin. This defies both common sense and well-established studies on the comparative risk of addiction.

Critics of rescheduling also deny that there is convincing evidence that marijuana or its compounds have any legitimate medical use. They cite research like a 2025 review paper that assessed 15 years of medical marijuana research and concluded that “evidence is insufficient for the use of cannabis or cannabinoids for most medical indications.”

This claim is problematic, however, given that the Food and Drug Administration has already approved several medicines that are based on the same active compounds found in marijuana. These include the drugs Marinol and Syndros, which are used to treat AIDS-related anorexia and chemotherapy-induced nausea and vomiting. Both of these contain delta-9-tetrahydrocannabinol, or THC, the substance that is responsible for the marijuana high.

If the active ingredients of marijuana have legitimate medical use as established by the FDA, then it stands to reason that so must marijuana.

Option 2: Moving marijuana to schedule III

Moving marijuana to schedule III would make it legal at the federal level, but only for medical use. Recreational use would remain federally prohibited, even though it is legal in 24 states as of early 2026.

The most obvious benefit to rescheduling, noted above, is that it would make research on marijuana easier. The system of cannabinoid receptors through which marijuana confers its therapeutic and psychoactive effects is crucial for almost every aspect of human functioning. Thus, marijuana compounds could provide effective medicines for a wide variety of ailments.

Contrary to the 2015 review mentioned earlier, studies have shown that cannabis is effective for treating nausea and AIDS symptoms, chronic pain and some symptoms of multiple sclerosis, as well as many other conditions.

Rescheduling could also improve medical marijuana guidance. Under the current system, medical marijuana users are not provided with accurate, evidence-based guidance on how to use marijuana effectively. They must rely on “bud tenders,” dispensary employees with no medical training whose job is to sell product. If cannabis were moved to Schedule III, doctors would be trained to advise patients on its proper use. On the other hand, medical schools need not wait for rescheduling. Given that many people are already using medical marijuana, some medical experts have argued that medical schools should provide this training already.

Rescheduling, however, is not without complications. To comply with the law, medical marijuana programs would have to start requiring a doctor’s prescription, just like with all other scheduled substances. And it could be distributed only by licensed pharmacies. That might be a good thing, if marijuana is as dangerous and addictive as critics claim. But advocates of medical marijuana might be concerned that this would increase costs to the consumer and restrict access. That concern might be mitigated, however, if health insurance companies are required to cover the costs of medical marijuana once it is rescheduled.

In addition, it is unclear how rescheduling would affect state-level bans on medical marijuana. Generally speaking, states cannot legally restrict access to pharmaceuticals that have been approved by the FDA. However, this principle of federal preemption is currently being challenged by six states claiming they have the authority to restrict access to the abortion medication mifepristone.

Option 3: Unscheduling marijuana

The debate over rescheduling ignores a third option: that marijuana could be removed entirely from the Controlled Substances Act, giving states the authority to allow medical marijuana to be distributed without a prescription.

Some of the objections to rescheduling come from marijuana advocates. Given that marijuana is safer and less addictive than alcohol – which is not scheduled under the Controlled Substances Act – a case could be made for removing it entirely from the list of scheduled substances and allowing states to legalize it for recreational use, as many states have already.

In fact, many drugs as, or more powerful than, marijuana are also not scheduled. For example, most over-the-counter cough medicines contain dextromethorphan, a hallucinogenic dissociative, which in large doses causes effects similar to PCP.

Removing marijuana from the list of controlled substances would also decriminalize the drug. Over 200,000 Americans were arrested for marijuana in 2024, over 90% of them for mere possession.

At the moment, the third option seems very unlikely. Although over 60% of Americans are in favor of full marijuana legalization, it lacks support in Congress.

Medical marijuana rescheduling looks likely to occur in 2026. After all, it has been proposed by both Biden and Trump. Whether it is the right move, only time will tell.

Under Salt Marsh: detective drama uses the Welsh coast to explore climate anxiety

Source: The Conversation – UK – By Sarah Olive, Senior Lecturer in Literature, Aston University

Morfa Halen means “salt marsh” in Welsh. This tidal island is a delicious invention of Sky Arts’ new detective drama, Under Salt Marsh, although it has very real antecedents in north Wales. Shell Island on the Mochras peninsula, near Harlech, inspired writer and director Claire Oakley.

Morfa Halen is cut off from the mainland nightly, when the tide swamps the causeway. This isolation is emphasised through an overhead shot of a car cutting a foamy, white swathe through the blues and browns of saltwater and sunken grasses. Immediately, Morfa Halen is established as the kind of closed community on which the detective genre thrives: think monasteries, country houses and Oxbridge colleges.

Under Salt Marsh uses familiar detective tropes to tell a story about environmental precarity and community displacement – but its treatment of Welsh language and identity is more conflicted than its ecological politics.

The opening moments establish that central character, Jackie Ellis (Kelly Reilly), cares. We see it when the primary school teacher soothes her pupils’ troubles. It is evident when she discovers her student Cefin’s body face down in a drainage ditch, breaks the news to his parents, then babysits their other children. She cares because something similar has happened before. Her niece, Nessa, disappeared at the same age, from the same town, and is presumed dead. A police officer at the time, Ellis was unable to solve the case.

Ellis immediately interferes in the investigation, questioning witnesses and ordering the police team around. They are led by Detective Eric Bull (Rafe Spall). He was Ellis’s junior partner when her niece went missing. She wants him pulled from the case, saying he messed up the investigation then betrayed her. He claims Ellis was suspended for gross professional misconduct.

The trailer for Under Salt Marsh.

Their antipathy is complicated: she lies for him on her own initiative, getting him out of a scrap with a local lad. The gesture pays off. By the end of episode two, Ellis drags a reluctant commitment out of Bull to an illicit co-investigation. So far, so standard detective fare: a professional v amateur odd couple.

Furthermore, Bull’s encyclopaedic knowledge of flora and fauna; willingness to work viscerally by tasting ditchwater and chomping on samphire; and queer sexuality repackage classic detective traits from the likes of Sherlock Holmes. However, Bull’s character updates his aristocratic precedent with an urban English accent and football club tattoo.

Imagined communities

Place and its influence on people’s thinking and behaviour has long made for compelling detective television, from the Oxford of Inspector Morse to the Scandinavian borderland of The Bridge.

Morfa Halen’s community faces displacement due to climate change. This is a reality along the north Wales coast. In the short term, a severe storm threatens a forced evacuation. Evidence of the crime will be washed away, making the investigators’ work a race against time.

Sea defences are being built by workers who temporarily swell the village’s population and offer additional lines of inquiry. The earliest clues come when Cefin’s autopsy detects the salinity of the water in his lungs although he drowned in a rainwater ditch, and acid on his skin associated with landfill sites. Illegal dumping is discovered in a former quarry on land owned by Cefin’s grandfather, Solomon Bevan (Jonathan Pryce).

The community’s “deep connection to the land” is both materialised on the corpse and called into question. The series feels fresh in its ecological concern, but salty in its environmental critique. Oakley told the audience at the preview I attended: “Salt marsh stores carbon, it is a buffer from erosion. If we don’t protect it, it can’t protect us.”

Oakley clearly loves the setting. She nails the rise and fall atmosphere of neglected seaside towns: the seasonal highs of ice cream parlours and lows of seasonal unemployment, the pretty painted cottages and drab pebble-dash bungalows. Oakley pours herself into the speech of a fellow incomer, an Irish engineer who has been motivated to oversee the flood defences by memories of childhood summers.

North Wales is established visually through a familiar repertoire: sea-to-mountain views; heavy rain and sheep. Though the rain was faked by machines, the sheep are real enough. However, the scene in which Solomon herds them into his own village pub to protest resettlement is fantastical (don’t sheep where you eat).

Characters of colour momentarily promise to redress the usual white default in constructions of Welsh identity, especially in the countryside. However, except for Irene, we barely hear from these characters in the first few episodes.

Audibly, the show is dominantly English. There are the Welsh accents of some actors, such as Pryce, although these are mainly south Walian. The few identifiably “Gog”/north Walian accents include those of Cefin’s cousins and mother. This reinforces the skew in media representation to Wales’ southeast.

The Welsh language is spoken occasionally, though more fleetingly than in the show’s nearest geographical and generic rival Hinterland (2013). The latter’s bilingual version was credited as the first BBC television drama featuring dialogue in both Welsh and English.

Sometimes Under Salt Marsh reinforces the Anglophone stereotype of the Welsh language being used as “code speak” to evade English ears. A family discusses what to do with evidence as the English-speaking police pass by unaware. Road and street signs make fleeting contributions but the scarcity of bilingual shop fronts, menus and display boards in the village undercuts its resemblance to north Wales.

Author Saunders Lewis’s proclamation that “Wales without the Welsh language will not be Wales” applies to the sight of Welsh, as well as its sound. The omission is, however, unlikely to be noticed by Sky Arts’ far-flung audience.

Watch Under Salt Marsh because it promises excellent environmentally engaged detective drama, not to learn about Wales or Welshness.

How to use cleanser properly – by an expert in skin science

Source: The Conversation – UK – By Rebecca Wagner, Postdoctoral Researcher, Stem Cell Biology and Single Cell Technologies, Karolinska Institutet

Cleansing is an important part of any skincare routine. leungchopan/ Shutterstock

Cleansing has long been an important part of hygiene rituals across cultures. Nowadays, cleansing remains an essential part of daily skincare routines, helping to remove sweat, makeup and old skin cells.

But with skincare routines becoming more and more extensive (and expensive), it can be difficult to know which cleanser to use – and how to use it. The right product can benefit skin health and overall wellbeing, while the wrong product could potentially damage the skin.

What does cleanser do?

Cleansers are designed to clean the surface of the skin. They remove excess oils, dirt and other products – such as makeup or sun cream.

Cleansers can be divided into four base ingredients: soap, detergent, surfactants and emulsifiers. These are all compounds with properties that allow them to solubilise particles – a process which allows particles (such as makeup or dirt) to be dissolved in water. This process separates these particles from the surface of the skin so they can be washed away – leaving the surface of the skin clean.

The first cleansers were soaps. These are relatively harsh on the skin as they strip away the skin’s natural oils, causing dryness or even irritation.

Most modern cleansers contain synthetic detergents, which are less irritating to the skin. Some cleansers also contain a higher proportion of lipids (fats). This prevents the skin from becoming dry by replacing the oils that are removed by cleansing.

When should we cleanse?

How often you should cleanse is a personal matter, depending on factors such as lifestyle, skin type and genetics.

For instance, if you have dry skin, cleansing less frequently or with milder products may suit your skin better. But if you’re someone with oily skin you may want to cleanse more often.

How do you pick the right cleanser?

The type of cleanser that works best for a specific person will vary depending on a whole host of factors such as skin type, age and lifestyle. So what works for one person doesn’t guarantee it will work well for the next.

Cleansers are typically made with a specific base ingredient – such as water or oil. Water-based cleansers remove water-soluble particles, such as dirt and sweat, while oil-based cleansers can remove oil-soluble particles, such as makeup and sun cream. Additional ingredients are also often added to cleansers to help provide specific results.

For example, salicylic acid is often found in cleansers for blemish control. It has anti-inflammatory properties and slows down cell growth.

Benzoyl peroxide, has anti-bacterial properties, which is why it’s useful in treating mild acne.

If you don’t have acne or a skin condition where these compounds have been proven useful, cleansers containing salicylic acid or benzoyl peroxide may be unnecessarily harsh and could harm the skin.

Cleansers containing ceramides, which are naturally-occurring lipids that are an important component of the skin barrier, may be a good option for those looking to protect their skin. The addition of ceramides to a cleanser means less of the skin’s natural oils are lost during cleansing.

Why is using the right cleanser so important?

The skin is delicate. If you use ingredients that are too harsh, it could negatively affect the skin.

For instance, soaps and detergents can be harsh on the skin – specifically to the skin’s lipid components, which are key to the skin’s function as a protective barrier.

Harsh cleansers (or cleansing too often) could also potentially disrupt the skin microbiome – the many different types of bacteria, fungi and viruses that live on our skin and are essential to overall skin health. should be fixed now

If the skin microbiome is disrupted, it could lead to a microbial imbalance, where one bacterial strain grows out of control. This could lead to breakouts or even exacerbate other skin issues, such as eczema.

Dry skin after cleansing may be a sign the skin barrier (the outer layer of dead skin cells that protect the underlying cells from harm) has been damaged. Moisturising after cleansing can combat this. Alternatively, using a cleanser that has a moisturising component – such as ceramides or a micellar water – may be helpful, though it’s still worth monitoring how your skin feels after cleansing.

How do you cleanse properly?

Washing your face with water alone won’t be enough to remove any oil, dirt or makeup that has built up.

Usually a single cleanse will work just fine for removing these things from the surface of the skin – including makeup.

Double cleansing is something that has been popularised by Korean beauty trends. This involves cleansing in two steps – first using an oil-based cleanser, which may work better to remove oily products (such as makeup or sunscreen), and following this up with a water-based cleanser. This procedure is meant to provide a deeper clean, which can be useful.

However, a water cleanser will not be very efficient at removing any residue that may be left behind from the oil cleanser. This could lead to a build-up of the oil-based cleanser which could lead to irritation or breakouts.

When deciding on how to cleanse and which products to use it’s important to consider what will be best for your lifestyle and your skin type. Just be sure your cleanser contains ingredients that allow you to clean your skin without destroying your skin barrier.

Trump 2.0: overhaul of counter-terrorism policy massively expands US list of bad guys

Source: The Conversation – UK – By Brian J. Phillips, Reader (Associate Professor) in International Relations, University of Essex

It’s only one year into Donald Trump’s second term as US president, and he has already massively transformed US counter-terrorism policy.

The list of designated terrorist groups has grown at an unprecedented rate. Counter-terror policies are being stretched to include drug cartels – with serious international consequences, as we saw in Venezuela at the beginning of January.

And, importantly, the US is taking these steps without its longtime allies.

Since early 2025, Trump has added a whopping 26 new groups to the Foreign Terrorist Organization (FTO) list. In most years since the list started in 1997, only two or so groups were added. The past 12 months have seen the largest single year increase in US-declared terrorist organisations.

The FTO list imposes serious consequences on listed groups. It is a felony for anyone to “materially support” an FTO, so a US citizen could be sent to prison for transferring funds to a group member.

Banks have to freeze funds of anyone associated with a designated group. Alleged associates of designated organisations can also be barred from entering the US or kicked out if already in the country.

Terrorist designation implies a great deal of work on the part of law enforcement, financial institutions, the military and others, first in identifying and then in pursuing and countering organisations on the list.

In the mid-2010s, at the height of the threat from the Islamic State, there were about 60 FTOs – now there are more than 90. With such an inflated list, it is unclear that officials can focus on the highest priorities.

Other FTOs continue to carry out or direct attacks, such as the Bondi massacre of Jewish people celebrating Hanukkah in Sydney in December 2025, or Iran’s Revolutionary Guard Corps plotting the assassination of Israel’s ambassador in Mexico in 2024.

Drug dealers or terrorists?

The main US terrorist list has sprawled beyond traditional terrorist organisations. These are defined as ideologically motivated groups using intentional violence against civilians to achieve political goals.

In February 2025, the Trump administration added 15 groups to the terrorist list that are probably best described as drug cartels or gangs – such as the Sinaloa cartel in Mexico and gangs in Haiti and Central America.

Most people in the US had probably never heard of these groups, such as Gran Grif in Haiti and Los Lobos in Ecuador.

Especially perplexing to many analysts is why criminal groups would be added to a terrorist list. There are already US sanctions for criminal organisations, such as the Kingpin Act, which bans financial transactions with drug cartels and freezes their assets.

Apart from anything else, it stretches the resources of US crime-fighting agencies away from actual terrorist groups. And it seems to green-light excessive and counterproductive policies toward criminal organisations. A growing body of research shows that counter-terrorism and counter-insurgency used against drug cartels or gangs often backfires, leading to increased violence.

This expansion of the “war on terror” to criminal groups has been used to justify more than 100 deaths (so far) in missile strikes, and the overthrow of Venezuelan president Nicolás Maduro. The Trump administration has justified the missile strikes with the language of counter-terrorism. Trump announced the first attack, on September 2 2025, with an explanation on social media indicating that the targeted group, Tren de Aragua, is an FTO.

There have now been 35 similar strikes, killing approximately 120 people.

America does not claim, however, that the targeted boats carry bombs or guns, the typical tools of terrorists. The boats are attacked because they are alleged to carry drugs – even though drug trafficking is almost never a death penalty offence in the US.

There have not been any missile strikes since Maduro’s capture on January 3. The US president justified the raid by saying that Maduro was the head of the Cartel de los Soles, which was designated as an FTO in 2025.

But, two days after Maduro’s capture, the US justice department dropped the claim that the cartel exists. It changed its indictment against the Venezuelan president to instead nominate him as sitting at the top of a system of corrupt patronage under which drug trafficking has flourished.

The US has certainly carried out regime change before, notably in Panama in 1989 when it captured and removed the country’s dictator, Manuel Noriega, who had been indicted before his capture. He was subsequently convicted and jailed in the US.

But the use of counter-terrorism law, language and lethal tactics abroad for drug traffickers – to this degree, in an extended military campaign – represents an unprecedented escalation.

A new path

These changes are all the more remarkable because they are part of a decoupling from traditional US allies on counter-terrorism. For decades, the US set the standard on counter-terrorism. Analyses of the dozens of terrorist lists around the world demonstrate that when the US designated a certain group as terrorists, its allies tended to follow suit – until 2025, that is.

Over the past year, the US has far outstripped all other countries when it comes to adding to the list of groups deemed to be “terrorists” proscribing terrorist groups. And most have not followed Washington down the road of listing criminal groups as terrorist organisations.

A few Trump-aligned Latin American countries, such as Argentina, labelled some of the cartels as terrorists. Canada also followed suit, listing seven cartels, but the move was widely reported to be part of an effort to gain a favourable trade deal.

States that historically copied US counter-terrorism priorities, from Australia to the UK, have not stretched their terrorist proscription regimes to include organised crime.

Longtime US allies have gone in another direction on counter-terrorism in recent years, proscribing far-right groups. The UK, for example, added two white supremacist networks to its terrorist list (alongside the pro-Palestine group Palestine Action) in 2025. The Trump administration did not include any far-right groups among its 26 new FTOs.

Overall, the decoupling of the US and its traditional allies is occurring more broadly than just on counter-terrorism, as the recent debate about Greenland makes clear. But when they can’t see eye to eye on who the main threats are, it begins to present a problem for the people tasked with keeping the world safe.

Scabies outbreak in UK and Europe – what you need to know

Source: The Conversation – UK – By Jo Middleton, Research Fellow in Public Health, Brighton and Sussex Medical School

Scabies cases are surging across the UK and Europe. The tiny mites that cause it spread easily through skin contact, making children, young adults and elderly people particularly vulnerable. Effective treatments are available, but myths and stigma are getting in the way of proper control.

What is scabies and how do people catch it?

Scabies is a skin infestation with tiny mites called Sarcoptes scabiei. The mites transfer from person to person through skin-to-skin contact – when parents cuddle children, care workers help residents, people share beds, or during sex. Occasionally, contaminated clothing or bedding can spread them too.

Are scabies cases rising in the UK, and if so why?

In institutions across England and Wales, such as care homes and schools, our team found 241 outbreaks in just one year.

In the wider population, the picture is less clear because scabies does not have to be officially reported to health authorities, and many people treat it themselves using over-the-counter medicines. However, reports from GP surgeries and sexual health clinics suggest cases have risen sharply over the last few years.

We don’t yet know all the reasons for this rise. However, one of the main culprits is that in 2023 and 2024 supply chain problems left pharmacy wholesalers struggling to stock imported scabies creams. With treatments delayed, more people became infested.

Who is most at risk of catching scabies?

Anyone can catch it, but three groups face the highest risk: children, sexually active young people and the elderly. This is mainly because these three groups tend to have more physical contact and are congregated in institutions like nurseries, universities and care homes. People in other crowded settings, such as migrant centres or prisons, are also at risk.

Is scabies caused by poor personal hygiene?

Absolutely not. Bathing habits make no difference to scabies rates. Unlike many bacteria and viruses, these mites tolerate soap and alcohol handwash just fine.

What are the symptoms?

Scabies usually causes an intense itch, particularly at night. However, these symptoms usually take around four to six weeks to arise if it is the first time someone is exposed.

Sometimes you can spot S-shaped burrows on the skin, particularly between fingers or on genital areas. In elderly patients, we’ve found scabies can look quite different – they may not even complain of itching.

How contagious is scabies and how long can mites survive off the body?

Scabies is highly contagious. Even a few minutes of skin-to-skin contact – such as holding hands – can be enough for a mite to crawl from one person to another. This is how most people become infested. Depending on room temperature and humidity, the mites can survive off the body for up to a week, but human skin is their natural habitat.

Why does scabies treatment sometimes fail or seem not to work?

Traditional cream treatments work well in ideal circumstances, but using them correctly can be difficult. The creams need to be put over the entire body and left on for hours. At the same time, clothing and bedding need to be washed, and close contacts, such as family members, need to be treated even if they have no symptoms.

This whole process then needs to be repeated seven days later. This is because the creams work excellently at killing the adult mites, but less well at penetrating egg-cases. The second treatment will kill the newly hatched mites before they have a chance to mate. Not carrying out any of these steps risks failing to eradicate the mites.

Even successful treatment can leave itching that persists for weeks, wrongly leading people to assume they’re still infested.

Why was an oral medication recently introduced?

In many countries, an oral medication called ivermectin has been available for treating scabies for many years – making treatment far easier. To tackle the surge in cases, my colleagues and I in the NIHR Applied Research Collaboration Kent, Surrey, Sussex were involved in getting the drug licensed and available on prescription in the UK. But like the creams, it usually needs repeating after seven days to be fully effective.

Is scabies becoming resistant to medicated cream?

There is evidence scabies mites in other countries have developed some resistance to permethrin, the medicated cream used to eradicate them. However, most treatment failures in the UK probably stem from the practical difficulties of using treatments correctly rather than the medication itself not working.

What are the emotional and mental health effects of scabies on patients and families?

The visible signs on skin, combined with the persistent myth about poor hygiene, create real problems. When we’ve spoken to patients and their families, they describe feeling ashamed, being judged by others, and withdrawing socially. Add in disrupted sleep from the itching, and the mental health impact can be serious.

Why do shame and embarrassment make scabies harder to control?

Early diagnosis and treatment reduce how many people catch it from an infected person. But shame causes delays – people put off seeking help for themselves, their family members, or even residents in their care. This gives the mites more time to spread.

What should people do if they think they have scabies?

If you are concerned about scabies, you should see your GP. They can examine your skin to determine if it is indeed scabies and put a treatment plan in place, if necessary.

Mexico and US look for new deal in long-running battle over 80-year old water treaty

Source: The Conversation – UK – By Natasha Lindstaedt, Professor in the Department of Government, University of Essex

Mexico City has experiencing years of low rainfall, leaving it often unable to supply its citizens with water.

The city, originally built on lakes and wetlands, is now covered in concrete and asphalt. Another factor is that Mexico City loses about 40% of its water through leaks.

The shortages have sent the price of water shooting up. One resident told ABC News that he now spends about 25% of his income on buying water. And in 2024 water was rationed in 284 of the city’s neighbourhoods.

But the problem extends well beyond Mexico City. Water shortages are projected to affect 30 of its 32 states by the year 2050, which is forecast to affect 40-80% of its population.

Despite all of these water shortages, Mexico is being forced to send part of its water supply to the US because of a just over 80-year-old agreement that was negotiated when water was less scarce. The 1944 treaty governs the allocation of water from the Rio Grande and Colorado River. Under the agreement, Mexico must send 430 million cubic metres of water per year from the Rio Grande to the US, and the US agreed to send 1.85 billion cubic metres a year of water from the Colorado River to supply the Mexican border cities of Tijuana and Mexicali.

US president Donald Trump recently threatened additional 5% tariffs on Mexican exports to the US, claiming that Mexico was 986.8 million cubic metres short of delivering water targets set out in the treaty.

While Mexico is facing its worst water crisis in decades, with reservoirs that serve over 23 million people drying up, it continues to be struggle with this water debt to the US.

Now Mexico has agreed to send 65 billion gallons of water (246 million cubic meters) north by the end of January 2026, about a quarter of the debt, in an updated deal that was finalised on December 15, with distribution to Texas starting in January 2026.

Trump and Mexico’s president Claudia Sheinbaum are expected to discuss further steps for Mexico to resolve its water debt by the end of January 2026. Sheinbaum has argued that there has to be recognition that Mexico has experienced years of drought.

Mexico has been dealing with droughts for years.

How is Mexico coping?

This isn’t a new problem. Mexico City is sinking at a rate of 20 inches a year, with the aquifer that provides 60% of the city’s water over pumped. Back in February 2024, there were concerns that Mexico City might even run out of water in months.

In the town of San Cristóbal, in the southern state of Chiapas, residents have had to travel at least 30 minutes to access water as the taps often run dry, while other residents claim they only have access to water for a few hours a day.

In March 2025 for the first time ever the US refused a request by Mexico to provide water to the border city of Tijuana, which was running out of water. Tijuana is a manufacturing hub just 27 miles south of San Diego, California, which depends on the Colorado River for 90% of its water.

About 97% of the Colorado River basin lies within the US, while about 60% of the Rio Grande runs through the Mexico-Texas border, with the rest running through Colorado and New Mexico.

Mexico has not consistently adhered to the water agreement since the early 1990s, and the agricultural sector in Texas has struggled to cope without the water being supplied. Texas lawmakers have made this a priority, calling on Trump to apply pressure on Mexico for not complying with the agreement.

And the pressure on Mexico is likely to continue as it must start to renegotiate the US-Mexico-Canada Trade Agreement this year.

It’s not just Mexico that is running out of water, according to a new report by the United Nations.

The report reveals that more than 50% of the world’s large lakes have lost water while 70% of the major aquifers are experiencing long term decline. This is likely to ramp up tension between neighbouring countries over water access, with the Mexico/US conflict being just part of the bigger picture.

Mexico and the US’s growing dispute over water rights further complicates an already strained relationship that must tackle existing challenges related to drug trafficking, security, migration and trade wars. Water is just the latest issue to rise to the top of the tension table.

There’s long-lasting, negative effects for children like Liam Ramos who are detained, or watch their parents be deported

When Immigration and Customs Enforcement agents detained Liam Conejo Ramos, a 5-year-old boy who is an asylum seeker, in Minneapolis on Jan. 20, 2026, the photos quickly became a flash point in the Trump administration’s aggressive immigration enforcement activity.

In one image, a man wearing a black uniform holds onto a gray and red Spider-Man backpack that the worried-looking young boy, wearing a blue bunny hat with floppy ears, has on his back.

Meanwhile, ICE and Customs and Border Patrol operations near schools have become increasingly common over the past year, spreading from Texas to Maine. While some parents in Minnesota have set up patrols around schools, there are families choosing to keep their kids home for days or weeks.

We are scholars of migration and children and childhood adversity.

Our research shows that exposure to severe immigration enforcement experiences during childhood carries long-term, significant consequences: These children are twice as likely to suffer from anxiety in young adulthood.

Why this matters

There is well-documented research showing how immigration enforcement has immediate negative effects on children and adults

Children whose immigrant parents are arrested, detained or deported often experience emotional and behavioral problems, including separation anxiety, school absenteeism, hyperactivity and other behavioral issues.

Yet, until recently, it has not been well understood how experiencing or being subjected to immigration enforcement actions affects children once they grow up to become adults.

That said, over three decades of research shows the clear links between traumatic childhood events and mental health problems in adulthood. Studies show, for example, that adults who experienced temporary separation from their parents as children are more likely to say they’ve experienced depression symptoms years later.

We decided to investigate whether a child being exposed to immigration enforcement actions – meaning the arrest of a parent, or detention of a close family member, for example – is associated with mental health problems among young adults who grew up in immigrant families.

How immigration enforcement unravels families

Our study first combined interviews and open-ended survey questions to define what it means to experience severe immigration enforcement during childhood.

We then examined the link between severe immigration enforcement actions and anxiety among 71 young adults – all U.S. citizens age 18 to 34 – who were raised in immigrant households in New York.

As children, all of these young adults witnessed or experienced the arrest, detention or deportation of an immigrant family member or a member of their communities. Three-quarters of the participants identified as Hispanic.

We analyzed our interviews to develop several criteria to determine what constitutes severe exposure to enforcement during childhood, considering factors like whether they witnessed a detention or arrest more than once, and how old they were when these experiences took place.

We found that approximately 26% of the survey participants – all of whom in this group were Hispanic, except one – had severe exposure to immigration enforcement actions during childhood. Not all of them had a parent who has been deported.

Some of these young people had relatives who had drawn-out cases in immigration court, or felt constant fear that their parents might be deported.

When we linked our interviews with survey data, our results were striking.

We found that young adults who experienced severe immigration enforcement actions as children were twice as likely to have anxiety, compared with young adults who did not have this experience when they were growing up.

Exposure to severe immigration enforcement actions as a child was not independently associated with depression as a young adult. But all the survey participants who said they were experiencing depression also reported anxiety symptoms – further evidence of a connection between severe immigration enforcement actions and anxiety among young people.

Lasting impact of today’s policies

Many legal experts and political observers say that the Trump administration’s immigration enforcement tactics in Minneapolis and in other cities are designed to intimidate and instill fear among civilians.

Children are not immune to these tactics, either as witnesses or as targets.

Federal immigration officers deployed tear gas, for example, on students at Roosevelt High School in Minneapolis on Jan. 8. Experiences like this constitute a major adverse childhood event, exposing children and adolescents to significant trauma.

We believe that we can learn from decades of adverse childhood experiences research, which clearly shows the link between childhood adversity and physical and mental health outcomes in adulthood.

The enforcement tactics ICE is using in Minnesota and other places in the U.S. today are likely, our research suggests, going to harm the next generation of U.S. citizens and residents.

As trauma researchers have long known, our bodies keep score over a lifetime. The question facing policymakers is not whether these enforcement tactics will cause lasting harm – our research suggests they would – but what human costs we, as a nation, are willing to bear.

Scientists have identified unique sounds for 8 fish species

Source: The Conversation – Canada – By Darienne Lancaster, PhD Candidate – Marine Ecology and Acoustics, University of Victoria

Have you ever wished you could swim like a fish? How about speak like one?

In a paper recently published in the Journal of Fish Biology, our team from the University of Victoria deciphered some of the strange and unique sounds made by different fish species along the coast of British Columbia.

Researchers have known for centuries that some fish make sounds, and the ancient Greek philosopher and scientist Aristotle even mentioned fish sounds in his writings. However, our understanding of which sounds are made by which fish species is extremely limited because it is difficult to pinpoint where a sound comes from underwater.

To accurately identify which sound is made by which fish, our team deployed an underwater acoustic localization array at sites in Barkley Sound, B.C. The localization array was designed by our project collaborator, Xavier Mouy, and it allowed us to precisely triangulate sounds to specific co-ordinates.

Using this triangulation and paired underwater video recordings, we were able to tie fish sounds to the correct species. We identified more than 1,000 fish sounds during our study, and successfully tied those sounds to eight different rocky reef fish species: copper, quillback, black, canary and vermillion rockfish, as well as lingcod, pile perch and kelp greenling.

We were particularly excited to identify sounds for canary and vermillion rockfish since these species had never been documented making sounds.

Differentiating fish sounds

We also wanted to investigate if different species sounds were unique enough to be differentiated from each other. We created a machine learning model using 47 different sound characteristics, like frequency (how high- or low-pitched the sound is) and duration (how long the sound is), to understand the unique differences in species calls.

For example, black rockfish make a long, growling sound similar to a frog croak, and quillback rockfish make a series of short knocks and grunts. The fish sound model was able to predict which sounds belonged to which species with up to 88 per cent accuracy. This was surprising and exciting to our team since many rocky reef fish species are very closely related.

Some fish species are known to make unique sounds during specific activities like courtship or guarding territory. Our research found that many species are also making sounds while fleeing from other fish.

For example, the copper and quillback rockfish both make significantly more grunting type sounds while being pursued by larger fish. We also documented sounds made during feeding activities and during aggressive activities like chasing.

Using sounds in future research

We also used stereo cameras in our research which allowed us to measure the length of the fish. We found that smaller fish make higher frequency (pitched) sounds than larger fish, which means scientists may eventually be able to estimate how big a fish is just by listening to its sounds. This discovery could be used in conservation in the future because estimating fish size is an important tool for effectively managing fish populations.

Our team plans to apply this research to improve marine conservation efforts. Now that we understand fish species sounds can be differentiated, there are many exciting possibilities for developing these acoustic tools into monitoring methods.

We can create species-specific fish sound detectors that will tell us where fish live without disturbing them. This has important implications for future conservation efforts, and the techniques we used can be adapted by scientists all over the world to decipher other fish calls.

Going forward, our team plans to develop a method of counting fish using acoustic recordings by examining the number of calls each species makes.

We also plan to compare the fish sounds we collected in Barkley Sound to fish calls made in other areas of British Columbia to see if fish have unique accents or dialects.

Using underwater sound recordings to study fish is highly beneficial. It is minimally invasive and acoustic recorders can collect information for months or years in hard to access or low visibility locations underwater. With more development, underwater acoustic monitoring could become an important new tool for conservationists and fisheries managers.
