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.

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.

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

Skin, mouth, lungs … it’s not just your gut that has a microbiome

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.

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 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 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.

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.

The world is in water bankruptcy, UN scientists report – here’s what that means

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.
