Britons become first to scale Mount Everest with the help of Xenon gas, organiser says
KATHMANDU (Reuters) -Four British climbers became the first to scale Mount Everest on Wednesday using Xenon gas, which helped them save several weeks that mountaineers need to get used to high altitudes, an official of their expedition organising company said.
Normally climbers spend several weeks or even months on the mountain to allow their bodies to adjust to higher altitudes before trying to reach the summit of the world's highest mountain. It is extremely dangerous to go up if the climber is not properly acclimatised.
The British climbers, who had inhaled Xenon gas in Germany before embarking on the expedition, climbed the 8,848 metre (29,032 ft) peak in less than five days after departing London, said Lukas Furtenbach of the Austria-based Furtenbach Adventures that organised the expedition.
They slept in special tents that simulate high-altitude conditions at home before heading to the mountain and used supplemental oxygen like other climbers during their ascent.
Xenon is a colourless and odourless gas found in very small amounts in the earth's atmosphere and is known to have some anaesthetic properties and medical uses.
'Xenon improves the acclimatisation and protects the body from altitude sickness and the effects from the hypoxic environment,' Furtenbach told Reuters in a text message from the base camp, referring to the low oxygen environment in the mountains.
Furtenbach, who has logged four Everest ascents, said Xenon gas was used by guides before but 'it is the first time for clients', or ordinary climbers.
Xenon made the climb safer and shorter as it kept the climbers properly acclimatised, he said.
'Shorter expedition also means less garbage, less resources, less human waste in this sensitive environment,' Furtenbach said. Piles of garbage dumped by climbers have been an issue on Everest in recent years.
American climber and guide Adrian Ballinger of the Alpenglow Expeditions company called the use of Xenon a 'stunt ... it's never seemed like the type of experience we want to provide.'
'Everyone should climb the mountain in a form they are proud of. If these climbers are proud of this style, then that's their choice,' Ballinger said.
Nepal has issued permits to 468 people to Everest during the current March-May climbing season and more than 200 have already topped the summit so far.

Offbeat NYC graffiti tour survives despite predicted drop in foreign tourism thanks to visitors from this country: ‘They're obsessed with street art'
These tourists see the writing on the wall. French art lovers are flocking to industrial Brooklyn in droves for quirky walking tours of warehouses sprayed with graffiti and street art. Advertisement The niche fascination is still going strong despite a major industry group projecting a nearly 20% drop in overall foreign tourism to the Big Apple this year. 5 Audrey Connolly of Graff Tours leads a tour of street art and graffiti in Bushwick, Brooklyn. Stephen Yang 'There are so many people in France that are obsessed with graffiti and street art: It's been a huge part of our business for years,' Bushwick-based Graff Tours tour guide Audrey 'Byte' Connolly told The Post. Advertisement Connolly, who has led walking tours of the hipster neighborhood's urban art for nearly a decade, attributing trailblazing cultural similarities in New York and Paris for the grand amour. As tour guides across the city report an absence of usual visitors from Canada, Australia, Germany and other nations — possibly over political boycotts and tariff-related economic fears — French tourists are largely unbothered, Connolly said. 'They're obsessed with street art — hopefully, they keep coming.' 5 Connolly leads a group of tourists — two French families and one group from Kansas City, Missouri — on a tour through industrial Bushwick. Stephen Yang Advertisement Germans and Israelis — who also represent large swaths of Graff Tour patrons — have not booked nearly as much this year, and school groups from Canada and China have also dwindled, Connolly said. Antoine Jacquet, a 23-year-old Graff Tours customer from Dijon, France, said its been more difficult to clear immigration hurdles under the Trump administration. But he was able to make the overseas trip himself, and even predicted foreign tourism will 'probably pick up with the new mayor Zohran [Mamdani],' referring to the Democratic mayoral nominee, a socialist, because 'his policies are more based out of Europe than to America.' New York City Tourism + Conventions, the city's tourism authority, recently said that some 2 million fewer visitors from other countries are expected to make the trip to the Big Apple in 2025, a loss of roughly $4 billion in foreign tourism dollars. Advertisement August is typically one of the busiest months for tours, Connolly said, but during weeks this year when she would've typically been working for seven days straight, she's spent entire days off without a booking. 'Tourism has big-down market effects: it affects hotels, it affects small businesses, it affects [the] local economy,' said Graff Tours president Gabe Schoenberg. The impact has been felt in trendy Bushwick, from thrift shops to restaurants that cater to Euro families in the hipster shopping district, added Schoenberg. 5 Antoine Jacquet, 23, of Dijon, France, expects that tourism to the US will tourism will 'probably pick up with the new mayor Zohran [Mamdani].' Stephen Yang As French tourism to the biz remains strong, Schoenberg still reports a roughly 10% drop in overall foreign visitors since last year — and is now trying too woo domestic tourists and locals with targeted social media ads. 'We did better this year with domestic tourism than years past,' he said. But 'a lot of domestic tourists don't see [graffiti] as art,' Connolly said. 'They're being told to fear New York and everything about it.' Schoenberg also attributed the reluctance of foreign tourists to visit New York City to 'backlash' over President Trump and his policies, as well rising transportation and food costs and fears over tariff-related price increases. Advertisement 'Even for a New Yorker, prices are going up and prices are going up exponentially,' he said. 'But locally, either exemptions for tourism or some type of incentive for tourism could also help.' 5 While French tourism remains steady, Graff Tours has still seen a roughly 10% drop in overall foreign visitors since last year — and is now trying too woo domestic tourists and locals. Stephen Yang 5 Graffiti writer The Ghostface Mims teaches a workshop at Graff Tours. Stephen Yang Advertisement The president of the tour company — which has a Los Angeles outpost as well — attributed diversity in its offerings as its key to staying afloat in uncertain times. Aside from industrial walking tours, Graff Tours' Bushwick site also offers spray painting classes and has hosted corporate events for the likes of Meta, L'Oréal and even hosted an influencer-filled launch party for Samsung this summer. 'The class revenue is significant compared to the tour revenue,' Schoenberg said. 'If I was relying on tours in general, I don't think I would still be in business.'

US faces $9.4bn tourism loss from new $250 visa fee targeting African countries
The United States could forfeit an estimated $9.4 billion in visitor spending over the next three years following the introduction of a new $250 'visa integrity fee,' according to industry groups, who warn the policy risks undermining tourism and costing thousands of jobs. The U.S. government recently introduced a $250 'visa integrity fee,' provoking concerns about negative impacts on tourism and economic activity. The Congressional Budget Office estimates the fee could generate $27 billion over ten years Industry experts however, claim the fee may lead to a loss of $9.4 billion in visitor spending and 15,000 travel industry jobs The United States' decision to introduce a $250 'visa integrity fee' on international visitors has triggered sharp criticism from the global tourism industry, with officials warning that the measure could deter millions of travellers and cost the U.S. economy billions. The $250 'visa integrity fee, ' part of the One Big Beautiful Bill Act signed on July 4, 2025, will take effect later this year. According to immigration law firm Envoy Global, it applies to all nonimmigrant visa holders which include students, tourists, temporary workers, and business visitors particularly from African countries. The fee is non-waivable, non-reducible, and charged on top of existing MRV, anti-fraud, and reciprocity fees. The policy has drawn particular concern across Africa, where high travel costs, tariff barriers, and strict visa regimes already limit access to the American market. For many middle-class travellers from Nigeria, Kenya, South Africa, and Ghana, an additional $250 charge could turn U.S. tourism into a privilege reserved for the ultra-wealthy. Economic Fallout According to the U.S. Travel Association, the fee is expected to reduce visitor spending by $9.4 billion and tax revenue by $1.3 billion over the next three years. The group also estimates that about 15,000 U.S. travel jobs could be lost as a result of fewer international arrivals. Forbes reports that these projections stand in sharp contrast to calculations by the Congressional Budget Office (CBO), which expects the fee to generate $27 billion over ten years, roughly $2.7 billion annually, for the U.S. Treasury. However, industry economists argue the CBO analysis focused only on revenue collection, excluding the wider economic fallout of reduced travel demand. 'By longstanding tradition, the Congressional Budget Office does not incorporate macroeconomic feedback effects into its traditional cost estimates, ' a CBO spokesperson told Forbes. 'We didn't specifically do a dynamic analysis of this provision.' Similarly, Tourism Economics, a division of Oxford Economics, estimates the $250 fee could discourage 5.4% of international visitors, almost one million trips annually. Fewer visitors mean reduced spending on hotels, restaurants, retail, and cultural attractions, which in turn lowers tax income and weakens job creation. Erik Hansen, senior vice president of government relations at the U.S. Travel Association, said: 'Congress made the mistake of assuming that this worldwide visa integrity fee would not have a big impact on visitors from countries like India or Brazil. This is the exact type of armchair public policymaking that is going to get us into a big mess.' While Hansen highlighted India as a 'bright spot' for inbound travel, with Indian tourists spending $13.3 billion in the U.S. in 2024, similar growth has been recorded across Africa. Demand from students, entrepreneurs, and leisure travellers has been rising since the pandemic, with airlines such as Ethiopian Airlines, South African Airways, and Royal Air Maroc expanding U.S. bound capacity. However, a new supercharge from Washington could halt this trajectory. For African students in particular, the cost comes on top of visa application charges, SEVIS fees, and proof-of-funds requirements. Analysts warn that the fee risks slowing down people-to-people exchanges, business travel, and academic opportunities that have traditionally linked the U.S. and Africa. And could redirect African families to more accessible destinations such as Canada, the UK, and China. Refund Controversy Congress has described the fee as refundable once a visa expires, provided all conditions are met. But with most U.S. visitor visas valid for ten years, the refund process appears impractical. ' The idea that you're going to give the government money and then wait around 10 years and remember to ask for it back, even if you followed the rules, is just absolutely crazy,' Hansen told Forbes. The CBO itself acknowledged that only 'a small number of people would seek reimbursement' and noted that the State Department would require years to create a refund system. Tourism Competitiveness at Risk The timing of the new fee raises further questions about U.S. tourism competitiveness and openness, especially as the country prepares to host global sporting events like the Olympics and the FIFA World Cup. A World Travel & Tourism Council (WTTC) report in June forecast that international visitor spending in the U.S. could fall by as much as $29 billion in 2025, the only major economy projected to see a decline. 'While other nations are rolling out the welcome mat, the U.S. government is putting up the 'closed' sign,' Julia Simpson, president and CEO of WTTC, said. Outlook Unlike travellers from over 40 countries, including Japan, South Korea, most of Western Europe, and Australia, who enjoy visa-free entry to the U.S. under the Visa Waiver Program, no African country is included. This means African travellers, already burdened with strict visa requirements, will be disproportionately affected by the additional $250 fee. Fewer Africans travelling to the U.S. could mean reduced cultural, academic, and professional exchanges, weakening U.S.–Africa ties at a time when China, Europe, and the Gulf states are aggressively courting African travellers. The fee could also discourage family visits, cutting remittance-linked travel flows, and make it harder for African SMEs and startups to access U.S. markets.

I went to Italy for the first time and left with 5 big regrets
I took my first trip to Italy in October 2022, visiting Venice, Rome, and Milan. I made some mistakes when booking and planning my trip that made it less fulfilling. During the six-day trip, I regretted being an annoying tourist and visiting hot spots. I never thought I'd be that annoying tourist until one afternoon in Venice, Italy. I never imagined I would regret touring the Colosseum in Rome. I couldn't have predicted I'd feel sour about spending one night in Milan. But as I've learned as a travel reporter, I make mistakes every time I visit a new place. My first visit to Italy was in October 2022 during a two-week backpacking trip through Europe. I traveled by train to four countries and spent six days exploring three Italian cities — Venice, Rome, and Milan. I had an amazing vacation, but it could have been even more fulfilling and sustainable if I'd known a few things beforehand. Squeezing three cities into a six-day trip was my first mistake. With three destinations to visit in six days, my trip to Italy felt like a race. It started with a two-night stay in Venice, and before I knew it, I was off to Rome. Roughly 48 hours later, I was on the train to Milan, where I spent just one night before hopping on a train to another European city. Traveling too quickly made me feel like I was always rushing. Going all the way to Milan for a single night didn't satisfy me. If I had selected just one destination, I would have been more present during my trip — and more environmentally conscious. Justin Francis, cofounder of the UK-based sustainable vacation company Responsible Travel, previously told Business Insider that longer stays are better for the planet than quick visits. "Fewer but longer trips mean fewer air miles, more money in local hands, and you'll have a more relaxing trip, too," Francis said. I thought visiting in October would help me avoid crowds. I was wrong. Traveling to Europe in the summer doesn't seem like a good idea. During peak season, the continent's hottest destinations are overwhelmed with tourists. So I thought booking my trip in October, during shoulder season (the time between peak and off-seasons) would help me avoid long lines and obstructed views. Well, I was wrong. In Venice and Rome, I shuffled down cobblestone streets with pedestrian traffic jams. I dragged my feet over tourist-packed bridges. I viewed ancient sites like the Colosseum through the phone screens of people standing in front of me. It seems the word is out about shoulder season. So next time I go to Italy, I'll take a winter trip. In Venice, I shouldn't have booked my stay outside the city. Spending three nights in a castle for $360 was an offer I couldn't pass up. After all, it was a unique opportunity to sleep like a queen in the tower of Castello di Roncade, which was only a half-hour drive from Venice. Though my stay was marvelous and a steal for the price point, I felt regret after learning that daytrippers can worsen overtourism in places like Venice by adding to the crowds without spending on accommodations. By not spending the night in the city itself, I wasn't contributing as much as I could have to the local economy. I should have researched etiquette before my trip. When it comes to tourism etiquette, I was wrong to assume my own sense of common courtesy would serve me well. After a walking tour in Venice, I hoped to sit down for lunch, but all the restaurants I passed were packed. Hungry and hot, I eventually cut my losses and stood in line for gelato before sitting on a shaded step to enjoy it. As I was about to take my first bite, the nearby authorities waved their hands up and down at me — a gesture I could only take to mean "get up." If I could do it again, I'd be more aimless. In Rome and Venice, I had a rigid schedule. I booked tours and planned every hour of my day to see as many highlights as possible. Every place I ventured to was one I'd seen repeatedly in films and on Instagram. Seeing these famous places in person was fascinating, but I felt like I was missing out on a sense of wonder. When I got to Milan, I dropped the agenda and walked around the city in hopes of discovering something myself. It paid off. I stumbled upon a 15th-century castle I'd never seen on social media — Castello Sforzesco. Walking through the gate, I felt like I'd stepped into a fairy tale. Brick walls and towers lush with overgrown vines surrounded me. Exploring the grounds of this castle was more fulfilling than the gondola ride in Venice or the Colosseum tour in Rome. And I think that's because I wasn't expecting it.
