Suitcases rattle against cobblestones. Selfie-snappers jostle for the same shot. Ice cream shops are everywhere. Europe has been called the world’s museum, but its record numbers of visitors have also made it ground zero for concerns about overtourism.

Last year, 747 million international travelers visited the continent, far outnumbering any other region in the world, according to the UN's World Tourism Barometer. Southern and Western Europe welcomed more than 70% of them, The Associated Press reported.

As the growing tide of travelers strains housing, water and the most Instagrammable hotspots in the region, protests and measures to lessen the effects of overtourism have proliferated.

Here's a look at the issue in some of Europe's most visited destinations.

What’s causing overtourism Among factors driving the record numbers are cheap flights, social media, the ease of travel planning using artificial intelligence and what UN tourism officials call a strong economic outlook for many rich countries that send tourists despite some geopolitical and economic tensions.

Citizens of countries like the US, Japan, China and the UK generate the most international trips, especially to popular destinations, such as Barcelona in Spain and Venice in Italy. They swarm these places seasonally, creating uneven demand for housing and resources such as water.

Despite popular backlash against the crowds, some tourism officials believe they can be managed with the right infrastructure in place.

Italy's Tourism Minister Daniela Santanchè said she thinks tourism flows at crowded sites such Florence's Uffizi Galleries that house some of the world's most famous artworks could be better managed with AI, with tourists able to buy their tickets when they book their travel, even months in advance, to prevent surges.

She pushed back against the idea that Italy — which like all of its Southern European neighbors, welcomed more international visitors in 2024 than its entire population — has a problem with too many tourists, adding that most visits are within just 4% of the country's territory.

“It’s a phenomenon that can absolutely be managed,” Santanchè told The Associated Press in an interview in her office on Friday. "Tourism must be an opportunity, not a threat — even for local communities. That’s why we are focusing on organizing flows.”

Where overtourism is most intense Countries on the Mediterranean are at the forefront. Olympics-host France, the biggest international destination, last year received 100 million international visitors, while second-place Spain received almost 94 million — nearly double its own population.

Protests have erupted across Spain over the past two years. In Barcelona, the water gun has become a symbol of the city's anti-tourism movement after marching protests have spritzed unsuspecting tourists while carrying signs saying: “One more tourist, one less resident!”

The pressure on infrastructure has been particularly acute on Spain's Canary and Balearic Islands, which have a combined population of less than 5 million people. Each archipelago saw upwards of 15 million visitors last year.

Elsewhere in Europe, tourism overcrowding has vexed Italy's most popular sites including Venice, Rome, Capri and Verona, where Shakespeare's “Romeo and Juliet” was set. On the popular Amalfi Coast, ride-hailing app Uber offers private helicopter and boat rides in the summer to beat the crowds.

Greece, which saw nearly four times as many tourists as its own population last year, has struggled with the strain on water, housing and energy in the summer months, especially on popular islands such as Santorini, Mykonos and others.

The impact of overtourism In Spain, anti-tourism activists, academics, and the government say that overtourism is driving up housing costs in city centers and other popular locations due to the proliferation of short-term rentals that cater to visitors.

Others bemoan changes to the very character of city neighborhoods that drew tourists in the first place.

In Barcelona and elsewhere, activists and academics have said that neighborhoods popular with tourists have seen local shops replaced with souvenir vendors, international chains and trendy eateries.

On some of Greece's most-visited islands, tourism has overlapped with water scarcity as drought grips the Mediterranean country of 10.4 million.

In France, the Louvre, the world’s most-visited museum, shut down this week when its staff went on strike warning that the facility was crumbling beneath the weight of overtourism, stranding thousands of ticketed visitors lined up under the baking sun.

Angelos Varvarousis, a Barcelona- and Athens-based academic and urban planner who studies the industry, said overtourism risks imposing a “monoculture” on many of Europe's hotspots.

“It is combined with the gradual loss and displacement of other social and economic activities,” Varvarousis said.

What authorities are doing to cope Spain's government wants to tackle what officials call the country's biggest governance challenge: its housing crunch.

Last month, Spain's government ordered Airbnb to take down almost 66,000 properties it said had violated local rules — while Barcelona announced a plan last year to phase out all of the 10,000 apartments licensed in the city as short-term rentals by 2028. Officials said the measure was to safeguard the housing supply for full-time residents.

Elsewhere, authorities have tried to regulate tourist flows by cracking down on overnight stays or imposing fees for those visiting via cruises.

In Greece, starting July 1, a cruise tax will be levied on island visitors at 20 euros ($23) for popular destinations like Mykonos and 5 euros ($5.70) for less-visited islands like Samos.

The government has also encouraged visitors to seek quieter locations.
To alleviate water problems, water tankers from mainland Greece have helped parched islands, and the islands have also used desalination technology, which separates salts from ocean water to make it drinkable, to boost their drinking water.

Other measures have included staggered visiting hours at the Acropolis.
Meanwhile, Venice brought back an entry fee this year that was piloted last year on day-trippers who will have to pay between 5 and 10 euros (roughly $6 to $12) to enter the city during the peak season.

Australian firefighters warned people on Monday to prepare for more bushfires in a "high-risk" summer, after blazes killed one person and incinerated more than 350 buildings in the southeast.

Weather conditions have eased since strong winds and temperatures topping 40C fed dozens of wildfires in southeastern Australia's Victoria, which declared a state of disaster on Saturday.

But officials said 12 major fires were still burning across the state.

Country Fire Authority chief officer Jason Heffernan said another "heating event" was expected towards the end of January, though its intensity was uncertain.

"We are early in the high-risk weather season," Heffernan told a news conference.

"There's been a lot of fire in the landscape. Much work will be done between now and then to contain these fires," he said.

"Whilst we join with community in the rebuilding and the relief and recovery of the fires that have been, we need to turn our minds to the fires that could be as the season continues."

More than 350 structures -- including over 65 homes -- have been lost so far in the state, officials said, with the number likely to rise as fire damage is assessed.

One person died in a fire near the town of Longwood, about two hours' drive north of state capital Melbourne, police say.

Emergency Management Commissioner Tim Wiebusch said weather conditions had become more favorable for firefighters.

"But that doesn't mean that the risk is over," he said.

"Whilst the conditions are easing in some parts of the state, even the slightest of winds are still causing those fires to move around."

High temperatures and dry winds combined last week to form some of the most dangerous bushfire conditions since the "Black Summer" blazes.

The Black Summer bushfires raged across Australia's eastern seaboard from late 2019 to early 2020, razing millions of hectares, destroying thousands of homes and blanketing cities in noxious smoke.

Australia's climate has warmed by an average of 1.51C since 1910, researchers have found, fueling increasingly frequent extreme weather patterns over both land and sea.

Some Supplements Can Make Your Medication Less Effective

Health experts warned that some supplements can interact with certain medications and reduce their effectiveness, according to Eating Well website.

While these supplements are usually sold over-the-counter, taking them without asking a health care provider can have dangerous impact on your health.

Naturopathic doctor Jacob Wolf said that for instance, some vitamin and mineral supplements can interfere with absorption of medications.

Other supplements can bind with medications, preventing the drug from being utilized in the body, or they may be metabolized by the same or similar pathways as medications, explains Wolf. That can have a dangerous impact on your health.

Top offenders include calcium, magnesium, iron, fiber, activated charcoal and vitamins C and K.

Minerals like calcium, magnesium and iron can bind with medications, especially levothyroxine, a drug used to treat hypothyroidism, said Wolf.

“This can impact how levothyroxine is utilized in the body, adversely affecting treatment,” he explained.

These minerals can also interact with antibiotics in the tetracycline and fluoroquinolone class, said pharmacist Amanda Corbett.

Taking these mineral supplements at the same time as antibiotics may reduce the bioavailability of the antibiotic, creating risks like bacterial resistance or ineffective treatment.

And while scientists affirm fiber is an important nutrient for digestive regularity, healthy cholesterol levels and blood sugar management, supplementing isn’t always a great idea, as large doses can impact the absorption of certain medications.

Fiber-rich foods are a cornerstone of blood sugar management, even for those taking blood sugar–lowering medications, like metformin.

Fiber may also impair the effectiveness of other drugs, including digoxin (which treats certain heart conditions) and levothyroxine for hypothyroidism, Wolf said.

Therefore, if you do choose to take a fiber supplement, Wolf recommended speaking with your health care provider about spacing out your fiber and medication doses.

As for activated charcoal, it is a form of carbon that is used in the emergency room to treat the ingestion of toxic drugs and poisons.

“Activated charcoal acts like a sponge and can bind to many medications. It is best to completely avoid activated charcoal if on any life-critical medication,” said Wolf.

For Vitamin C, it is an important antioxidant that protects cells from free radical damage and supports proper immune system function.

However, if you are undergoing chemotherapy treatment for cancer, experts strongly caution against taking vitamin C supplements.

“Vitamin C can lead to certain chemotherapies being less effective or ineffective in treating cancer,” said Corbett.

Vitamin E, another antioxidant, can also interfere with chemotherapy’s effectiveness.

If taking Vitamin K, which is a fat-soluble vitamin that helps blood clot and shores up bone health, you should know that it can reduce the effectiveness of a blood-thinning medication called warfarin (Coumadin).

That, in turn, can make blood more likely to clot, which can lead to a heart attack or stroke.

If you are taking warfarin, you don’t necessarily need to avoid vitamin K, but it is critical to keep the amount you consume—from both foods and supplements—consistent to avoid clotting problems.

Experts advise that to take supplements safely, consult with your health care provider.

Many supplements can interact with medications, and so it’s critical to connect with your prescribing health care provider to make sure that the supplements you’re taking play nice with your medications.

Also, look for those that have been independently tested in a laboratory, recommended Corbett.

Experts say you should also know how much to take. Supplement dosages are listed on the label, but they aren’t standardized.

That means they can vary from product to product, and may far exceed safe levels.

 

 

 


Rejuvenated Human Eggs… Scientists Revolutionize IVF Success

Rejuvenated Human Eggs… Scientists Revolutionize IVF Success

German scientists claim to have “rejuvenated” human eggs for the first time in an advance that they predict could revolutionize IVF success rates for older women.

The groundbreaking research suggests that an age-related defect that causes genetic errors in embryos could be reversed by supplementing eggs with a crucial protein, according to The Guardian.

When eggs donated by fertility patients were given microinjections of the protein, they were almost half as likely to show the defect compared with untreated eggs.

If confirmed in more extensive trials, the approach has the potential to improve egg quality, which is the primary cause of IVF failure and miscarriage in older women.

The decline in egg quality is the main reason IVF success rates drop steeply with female age and is why the risk of chromosome disorders such as Down’s syndrome increases with maternal age.

“Overall we can nearly halve the number of eggs with [abnormal] chromosomes. That’s a very prominent improvement,” said Prof Melina Schuh, a director at the Max Planck Institute for Multidisciplinary Sciences in Göttingen and a co-founder of Ovo Labs, which is aiming to commercialize the technique.

“Most women in their early 40s do have eggs, but nearly all of the eggs have incorrect chromosome numbers,” added Schuh, whose lab has been investigating egg biology for the past two decades. “This was the motivation for wanting to address this problem.”

The latest approach targets a vulnerability in eggs linked to a process called meiosis, in which sex cells (eggs or sperm) jettison half their genetic material so they can join together to make an embryo.

In eggs, this requires 23 pairs of X-shaped chromosomes to align along a single axis in the cell. On fertilization, the cell divides causing the chromosome pairs to be – ideally – neatly snapped down their centers to create a cell with precisely 23 single chromosomes from the mother, the rest being delivered by the sperm.

However, in older eggs the chromosome pairs tend to loosen at their midpoint, becoming slightly unstuck or detaching entirely before fertilization.

In this scenario, the X-shaped structures fail to line up properly and move around chaotically in the cell, so when the cell divides they are not snapped symmetrically.

This results in an embryo with too many or too few chromosomes.

Schuh and colleagues previously found that a protein, Shugoshin 1, which appears to act as a glue for the chromosome pairs, declines with age. In the latest experiments in mouse and human eggs, they found that microinjections of Shugoshin 1 appeared to reverse the problem of chromosome pairs separating prematurely.

Using eggs donated by patients at the Bourn Hall fertility clinic in Cambridge, they found that the number showing the defect decreased from 53% in control eggs to 29% in treated eggs. When they looked only at eggs from women over 35 years of age, a similar trend was seen (65% compared with 44%), although this result was not statistically significant, which the scientists said was probably due to them only having treated nine eggs in this age range.

Dr Agata Zielinska, a co-founder and co-CEO of Ovo Labs, said: “Currently, when it comes to female factor infertility, the only solution that’s available to most patients is trying IVF multiple times so that, cumulatively, your likelihood of success increases. What we envision is that many more women would be able to conceive within a single IVF cycle.”

The findings will be presented at the British Fertility Conference in Edinburgh on Friday and have been published as a preprint paper on the Biorxiv website.
