In travel news this week: five Americans living in France and loving it, inside the cockpit of a self-landing plane, plus sweaty secrets of the TSA security checkpoints.

It’s been a sizzling summer so far in the United States and Europe, but there’s one lesser-known side effect of all these high temperatures.

Heavy perspiration can earn you a pat-down at airport security, particularly if it’s pooling in intimate pouches.

Ever had the machine go off and the security officer had to wave over you with the magic wand? Moistness might well have been the problem.

We asked the TSA to explain why this happens.

“Added moisture from a person’s body can alter the density of clothing, so it is possible perspiration may cause our Advanced Imaging Technology machines to alarm,” a spokesperson said.

“If this occurs, the passenger may need to undergo additional screening, such as a pat-down in the area of the body where the AIT alarmed, to ensure there is no threat.”

Sweatiness or otherwise, TSA lines will move a little faster from now on, since on Tuesday TSA removed the requirement for all passengers to take off shoes at airport security checkpoints.

Our video has the details.

The 3.4 ounce liquid rule remains in place, but there is one TSA-approved hack that allows travelers to bring a bottle of water past the scanners.

It takes a little planning, but your beverage will undoubtedly be refreshing. Here’s how it works.

To help you navigate high temperatures this summer — and know when extra hydration is important — CNN has produced a US heat-risk tracker.

“I had the dream of France … But the dream was not as easy as I thought at all,” says Colorado woman Jennie Vercouteren, who moved with her husband, Ward, to the French Pyrenees in 2016.

The pair entered the property management business and, while things got off to a shaky start, Vercouteren says, “We don’t regret making the decision. I love how beautiful and calm life here is.”

The Zuerchers, a Florida couple in their early 60s who recently moved to Nice, in the south of France, agree.

“Nice is what Florida wishes it was,” is Pennie Zuercher’s take on the French city. “Every country has its issues,” Geoff says, “so we’re not walking around with rose-colored glasses like France is perfect, but it really fits us.”

Proving that a fresh start can be made at any age, California woman Carole Carson says that relocating to France at the age of 80 saved her life.

She now writes for her hometown paper back in Nevada City, California, and has published four novels. “Something about being freed from expectations of who I was based on who I’d always been, allowed me to be the writer I’d always wanted to be …” she says. “I was free to recreate myself once again.”

One word of caution, though, given all our talk of high temperatures.

Western Europe just had its hottest June on record and air conditioning is still very rare in the region’s homes. Here’s why.

Giant 13-inch shoes found in ancient Roman fort near Hadrian’s Wall

Published

on



CNN
 — 

An ancient Roman mystery is afoot in the rolling hills of northern Britain.

Archaeologists have unearthed a stash of unusually large shoes at the ruins of a first-century military fort along Hadrian’s Wall, a 73-mile (117-kilometer) stone barrier that famously shielded the Roman Empire’s northwestern perimeter from foreign invaders. The discovery is raising new questions about the lives and origins of the fort’s inhabitants.

The giant leather soles were found at Magna Fort in May among 34 pieces of footwear, including work boots and baby-sized shoes, that are helping to paint a picture of the 4,000 men, women and children who once lived in and around the English site just south of the Scottish border.

Eight of the shoes are over 11.8 inches (30 centimeters) in length — a US men’s size 13.5 or greater based on Nike’s size chart — making them larger than average by today’s standard and sparking suspicions that unusually tall troops may have guarded this particular fortress at the empire’s edge.

By contrast, the average ancient shoe found at a neighboring Roman fort was closer to a US men’s size 8, according to a news release about the discovery.

“When the first large shoe started to come out of the ground, we were looking for many explanations, like maybe it’s their winter shoes, or people were stuffing them, wearing extra socks,” recalled Rachel Frame, a senior archaeologist leading the excavation. “But as we found more of them and different styles, it does seem to be that these (were) just people with really large feet.”

As digging continues at Magna Fort, Frame said she hopes further investigation could answer who exactly wore these giant shoes. A basic sketch of the site’s past is just starting to come together.

When the Magna Fort was in use, multiple different Roman military troops and their families moved into the site every few years after it was built around AD 85, archaeologists suspect.

Inscriptions on the fort’s walls and altars recount settlements of Hamian archers from what is now Syria, Dalmatian mountain soldiers from Croatia and Serbia, and Batavians from the Netherlands, but the length of time each group stayed at the stronghold remains unknown.

Likely following orders from the Roman army, the troops would often leave the fort for distant regions and in their haste, ditch shoes, clothing and other belongings in the surrounding trenches, Frame explained.

Additionally, new occupants requiring more space would have built larger structures on top of the existing fort, packing rubble and clay between the walls and trapping any belongings left by the previous tenants, Frame said.

“As archaeologists, we like trash,” said Dr. Elizabeth Greene, an associate professor of classics at the University of Western Ontario. “You get those habitational layers where things were just left behind, maybe forgotten about, and that tells us more about the space.” Greene has studied thousands of shoes collected from the nearby Vindolanda Roman Fort, which has been excavated since the 1970s and is among the most well-studied of the Roman forts along Hadrian’s Wall.

The recently discovered Magna shoes share some similarities with those in the Vindolanda Fort collection, said Greene, who was not involved in the Magna excavation process, but has viewed the artifacts.

For one, the soles of the shoes from both sites are made from thick layers of cowhide leather held together with iron hobnails, she explained. While only a couple of the shoes discovered at Magna have some of the upper portions still intact, the Vindolanda Fort shoe styles include closed military boots and open work boots, as well as sneaker-like shoes reaching just below the ankle and sandals with leather fasteners.

It’s likely that the leather soles of the Magna shoes survived thousands of years in the ground thanks to ancient tanning techniques that used crushed up vegetative matter to create a water and heat resistant coating, Greene said. Testing is still underway to confirm this hypothesis.

Only two of the 34 shoes discovered at Magna Fort have the upper portions attached.

The length of the extra-large Magna shoes suggests the original owners may have been exceptionally tall, Greene said. At Vindolanda, only 16 out of the 3,704 shoes collected measured over 11.8 inches (30 centimeters).

Ancient Roman military manuals often described the ideal recruit as being only 5 feet, 8 inches or 5 feet, 9 inches in height, according to Rob Collins, a professor of frontier archaeology at Newcastle University in England. But the soldiers stationed around Hadrian’s Wall came from all around the far-reaching empire, bringing a wide diversity of physical traits to their settlements, he said.

Still, why Magna specifically might have needed troops of towering stature remains unclear.

To piece together the shoe owners’ identities, researchers will examine the Magna shoes for any signs of wear, Frame said. Any foot impressions left in the shoes could be used to model the feet of the original wearers.

Linking the shoes to real human remains, however, could prove difficult. For one, the Romans near Hadrian’s Wall generally cremated their dead, using a headstone to mark the graves, Collins said. Any bones that remain around the settlements are likely from enemy, illegal or accidental burials.

So far, the few bones that have been found at the Magna site were too soft and crumbly to provide insight, Frame said, but the team continues to search for new burial spots. Pottery and other artifacts found around the site may also help with dating and matching the timelines of the known occupants, she said.

But the researchers worry they could be running out of time.

Excavation of Magna Fort began in 2023.

The 2,000-year-old leather found at both the Vindolanda and Magna sites is preserved by the anaerobic, or low-oxygen, conditions of the soil, Frame said.

The 34 shoes found at the Magna fort, however, are in worse condition than those retrieved from Vindolanda decades ago — a problem Frame attributes to the changing climate.

“The more our climate changes, the more we get heat waves and droughts, or months’ worth of rain in one weekend type (of) scenarios, the more that influences the underground soil conditions and introduces more oxygen into these environments,” Frame explained.

In oxygen-rich soil, microbes thrive, contributing to decay, and acidic pH levels erode natural materials like leather.

Frame said the rapid weather changes only make their excavation of Magna more urgent.

“I’m not saying I don’t get excited about the shiny objects and precious treasures, but for me, archaeology is about the story of everybody else … the stories of the people whose lives weren’t written down, who weren’t kings or emperors or famous heroes,” she said. “These personal objects really put the real human people back into the picture.”

As South Korea becomes a key arms supplier to US allies, its best customer is on the edge of a warzone

Published

on


Seoul, South Korea
CNN
 — 

Poland has finalized a deal to acquire a second batch of 180 South Korean tanks under a 2022 agreement that will eventually see Warsaw boost its arsenal with almost 1,000 of the armored vehicles.

The deal underlines Poland’s emergence as a substantial European military force, as well as South Korea’s status as a major arms supplier – especially to US allies as wars around the world exhaust American stockpiles.

It comes as Russia ramps up attacks on Ukraine, some of which have come within 100 miles of Polish territory on Ukraine’s western border.

Warsaw has been increasing defense spending since Russia’s invasion of Ukraine, acquiring new weaponry while also helping Kyiv with its defense.

As a NATO member bordering Ukraine, it is seen part of the alliance’s first line of defense should Russian leader Vladimir Putin decide to expand his aggression beyond Ukraine.

Poland’s Defense Ministry announced the tank deal, which still needs to be formally signed, in a post on social media platform X earlier this month.

It put the price tag at $6.7 billion and said that includes 80 support vehicles, ammunition, and logistics and training packages for the Polish Army.

The deal for the K2 main battle tanks, regarded as among the world’s most powerful, includes units to be made in South Korea by defense giant Hyundai Rotem and the establishment of a production line in Poland for a Polish variant, the K2PL, according to South Korea’s Defense Acquisition Program Administration (DAPA), which oversees Seoul’s foreign military sales.

A K9 Thunder self-propelled howitzer takes part in an Armed Forces Day military parade in Warsaw, Poland, on August 15, 2023.

Sixty of the batch of 180 tanks will be built in Poland, the Polish Defense Ministry’s post on X said. The first 30 of the South Korea-made tanks included in the new contract are expected to arrive in Poland next year, it said.

In 2022, the two countries signed a deal for Poland to get 180 K2s. All but about 45 of those have been delivered, with the remainder expected to arrive in Poland by the end of the year, Hyundai Rotem said.

That framework was considered South Korea’s biggest overseas defense deal ever. It included a total of 980 K2s, 648 self-propelled K9 armored howitzers, and 48 FA-50 fighter jets, the Polish Defense Ministry said at the time.

The ministry said the armored vehicles would, in part, replace Soviet-era tanks that Poland has donated to Ukraine to use in its fight against Russia.

A March report from the Wilson Center based in Washington, DC, said Poland has given Ukraine more than 300 tanks and more than 350 infantry fighting vehicles and armored personnel carriers.

Poland has been on edge in recent days after Russia ramped up drone attacks on Ukraine.

A Russian drone barrage against the northwestern Ukrainian city of Lutsk was so intense it caused Warsaw to scramble fighter jets as a precaution. Lutsk is about 50 miles from the Polish border.

A NATO report from April cited Polish efforts to dramatically increase defense spending in the face of the Russian threat. Warsaw’s defense spending has grown from 2.7% of GDP in 2022 to an expected 4.7% in 2025, according to the report.

“Of all NATO allies, it spends the highest percentage of its GDP on defense,” the NATO report said.

It noted Poland’s purchase of South Korean arms to quickly fill gaps left by donations to Ukraine.

The Wilson Center report said Poland has “arguably emerged as Europe’s most capable military power.”

But a May report from the RAND Corp think tank expressed caution over the financing of Poland’s arms buildup.

Many of its purchases are “financed through direct loans from countries supplying equipment,” RAND said, adding: “If securing such loans proves impossible, market financing might be too expensive to turn framework agreements into binding contracts.”

RAND also said Poland faces recruitment challenges, needing to increase troop strength by almost 50% in the next 10 years.

Ukrainian President Volodymyr Zelensky and Poland's President Andrzej Duda greet each other as they arrive for their meeting outside Mariinskyi Palace in Kyiv, Ukraine on June 28, 2025.

Meanwhile, South Korea has emerged as the world’s 10th-largest arms exporter over the past five years, according to the Stockholm International Peace Research Institute.

Over that span, Poland has received 46% of South Korean military exports, followed by the Philippines at 14% and India at 7%, according to the SIPRI’s Trends in International Arms Transfers 2024 report.

As the war in Ukraine has dragged on, as well as Israel’s war in Gaza, US military aid for Ukraine and Israel has drained its arms stockpiles. South Korea is therefore increasingly seen as an option for US allies in need of weapons, according to a 2024 report from the DC-based Stimson Center.

And Seoul’s arms industry may become important to Washington in the future, the report said.

“Increased South Korean defense industrial base capacity, particularly in arms and shipbuilding, has the potential to directly support the United States,” the report said.

Shipbuilding is seen as a particular area of South Korean military industrial strength, and Washington has already seen contracts for maintenance of US Navy supply ships go to South Korean yards as the Navy grapples with a backlog in US shipyards.

Along with the K2 tanks, South Korea has sent 174 K9 howitzers to Poland under the 2022 framework, with 38 remaining to be delivered, according to contractor Hanwha Aerospace.

A second tranche of 152 K9s is in the works, Hanwha said.

Of the 48 FA-50 jets ordered, only 12 have been sent so far, according to manufacturer Korean Aerospace Industries.

Scotland faces up to its drug crisis by offering the UK’s first supervised injection facility

Published

on



CNN
 — 

In a quiet corner of Glasgow’s East End, a radical public health experiment is underway. For the first time in the United Kingdom, people who inject illicit drugs such as heroin and cocaine can do so under medical supervision – in a safe environment and indoors.

No arrests. No judgment. No questions about where the drugs came from – only how to make their use less deadly.

The facility, known as the Thistle, opened in January amid mounting political and public health pressure to confront Scotland’s deepening drug crisis. With the highest rate of drug-related deaths in Europe, Scottish health officials say, there have long been calls for a more pragmatic, compassionate response.

Funded by the devolved Scottish government and modelled on more than 100 similar sites across Europe and North America, the pilot safe drug consumption facility marks a significant departure from the UK’s traditionally punitive approach to illegal drug use.

Dorothy Bain, who heads Scotland’s prosecution service and advises the government, told a UK parliamentary committee in May that “it would not be in the public interest to prosecute users of the Glasgow safer drug consumption facility for possession of drugs for personal use.”

She added that the approach would be kept under review to ensure it “is not causing difficulties, raising the risk of further criminality or having an unlawful impact on the community.”

Supporters describe it as a long-overdue shift toward harm reduction. Critics warn it risks becoming a place where damaging addiction is maintained, not treated.

Located in a low-slung clinical building near the city center, the Thistle is a space where individuals bring their own drugs, prepare them on site, and inject under the watchful eyes of trained staff.

The service provides no substances, nor does it allow drug sharing between users. What it offers instead is clean equipment, medical oversight, and a protected environment for a population who might otherwise use in alleyways, public toilets or dumpster sheds, with the associated risks for themselves and the wider community.

“We’ve had almost 2,500 injections inside the facility,” Dr. Saket Priyadarshi, the clinical lead of the Thistle, told a CNN team who visited the facility in early June. “That’s 2,500 less injections in the community, in parks, alleyways, car parks.”

All users must register before receiving support, providing only their initials and date of birth. Staff ask what drugs they plan to use and how. Then, they observe – not intervene – ready to act in the event of an emergency.

“We’ve had to manage over 30 medical emergencies inside the facility,” Priyadarshi said. “Some of them were severe overdoses that most likely would have ended in fatalities if we hadn’t been able to respond to them immediately here.”

Nurses work with patients to reduce harm wherever possible, advising on injection technique, equipment, and vein placement.

“We’ll spend a bit of time with them. Just (to) try and get the vein finder working,” said Lynn MacDonald, the service manager at the facility, referring to a handheld device that uses infrared light to illuminate veins beneath the skin.

“People have often learnt technique from other people who are using it and it’s not particularly good,” she told CNN. With equipment such as vein finders, she said, the staff at the Thistle are able to highlight “better” sites of injection to “reduce harm and make the injection safer.”

Service manager Lynn MacDonald demonstrates how to use the vein finder.

The Scottish government told CNN that the service has already delivered results in terms of public health.

“Through the ability of staff to respond quickly in the event of an overdose, the Thistle service has already saved lives,” Scottish health secretary Neil Gray said. The service, he said, is “helping to protect people against blood-borne viruses and taking used needles off the street.”

The Thistle bears little resemblance to a medical clinic. There are no fluorescent white lights, no clinical uniforms, and no sterile white rooms. Even the language has been reimagined: users aren’t brought into “interview rooms,” but welcomed into “chat rooms.”

The space itself is soft and deliberate, – furnished with books, jigsaws, warm lighting and a café-style area where people can sit, drink tea, shower, or have their clothes washed.

“The whole service is just designed to that ethos of treating people with a bit of dignity, a bit of respect, bringing them in, making them feel welcome,” Macdonald told CNN. “We want them to leave knowing somebody cares about them and we’re looking forward to seeing them safe and well again.”

For Margaret Montgomery, whose son Mark began using heroin at 17, the existence of the Thistle offers a degree of solace that once felt impossible.

Margaret Montgomery says her son struggled with drug addiction for 30 years.

Now in his fifties, Mark is no longer using – but it took years, and distance, to get there.

“My son went into treatment and it’s like six weeks, three months, six months. That’s not enough time. There’s no aftercare,” Montgomery told CNN.

She added that she’d asked her son whether he would have used the Thistle “all those years ago.”

“He said, ‘yes, I probably would have used it because of the other facilities that they’re offering in there.’” Mark declined to speak with CNN himself but was happy for his mother to recount his experience.

What the Thistle represents, for Montgomery, is not approval – but reprieve. “Nobody wants to think their children are taking drugs anywhere,” she said. “There must be parents that are sat out there and they’re going, ‘well thank god he’s going in there and he’s doing that in there, not in a bin shed.’”

Her support is unflinching – and practical. She is the chairperson of a family support group that was consulted about the Thistle.

“I think the Thistle’s the best thing that’s happened in Glasgow,” she told CNN.

‘Ethical and moral question’

Others see the facility not as an act of compassion, but as a quiet surrender.

Annemarie Ward, who has been in recovery for 27 years, believes that without a clear route to abstinence, harm reduction risks becoming a form of institutionalized maintenance.

“Have we given up trying to help people? Are we just trying to maintain people’s addictions now?” she told CNN.

Ward, who is from Glasgow, is the chief executive of the charity Faces and Voices of Recovery UK (Favor UK), and a campaigning voice for better access and treatment choices for those seeking help with addiction.

For Ward, the danger lies not in what the Thistle does, but in what it omits: a vision of freedom from dependency. Without that, she argues, the ethics of such facilities become blurred.

Discarded paraphernalia used by drug users is pictured in Glasgow in December 2020.

“If our whole system is focused on maintaining people’s addiction and not giving them the opportunity to exit that system,” she said, “I think there’s an ethical and moral question that we need to ask.”

The Thistle is “just prolonging the agony of addiction,” she said. “If you know anybody who’s suffered in that way or loved anybody that’s suffered that way you would see how inhumane this actually is.”

But Glasgow City Council says that the facility is one strand of a broader strategy.

The council says that the Thistle does not divert “from other essential alcohol and drug services in the city,” adding that the local authority “also invests heavily in treatment and care and recovery services.”

“Comparing these interventions is not helpful,” the council said in a statement. “All services are equally important – and needed – to allow us to support people who most need them.”

The idea itself is not new.

The world’s first safer drug consumption room opened in Switzerland in 1986 -– a clinical counterpoint to street-level chaos. Since then, the model has spread across Europe, from Portugal and the Netherlands to Germany, Denmark and Spain, and beyond to Canada and New York City.

The Thistle, the UK’s first iteration, operates 365 days a year, and shares its premises with addiction services and social care teams.

The

As of June, 71.9% of drugs injected inside were cocaine, with heroin making up a further 20%. The users are overwhelmingly male. Most have been injecting for years; all are at risk.

Still, resistance remains. CNN spoke to several people in the area who were concerned about the facility’s opening and said it had encouraged more drug users to come to the area in the six months since opening.

Others, however, told CNN that they had noticed there were fewer needles and less discarded drug paraphernalia on the ground since the clinic opened.

Chief Inspector Max Shaw, of Police Scotland, told CNN that the force was “aware of long-standing issues in the area” and was “committed to reducing the harm associated with problematic substance use and addiction.” He added that officers would continue to work with local communities to address concerns.

For the nurses, doctors and support staff who work in the building, the mission remains immediate: delivering potentially life-saving support to those in need.
