Don't panic - five ways to stop your kids' endless scrolling

Excluding schoolwork, US teenagers spend as long as eight hours a day on entertainment and social screentime, and about half of them spend four hours or more on social media, such as YouTube, TikTok, and Instagram. That’s way too long for growing kids who should be engaged in real, face-to-face social activities, such as playing sports and hanging out with friends. But they want to keep up with rapidly changing fads and trends on social media. Also, auto-play and infinite scrolling glue their eyes to the display. Last December, Australia banned under-16s from using major social media services. Also, the EU is advancing region-wide legislation to restrict social media use for minors. Instead of just banning or restricting the use of social media help kids reduce gazing at and scrolling on smartphones, experts suggest some tips for parents to help their children reduce their screentime. The question is whether parents guide their children on how to use the smartphones they have grown up with?

Dear MEL Topic Readers, 

What happens to your brain in space?

In space where gravity is close to none, our body functions deteriorate. Muscles quickly weaken and shrink because they no longer have to fight Earth’s gravity to maintain posture or move around. Bones quickly lose density without the mechanical stress of weight-bearing. That’s why astronauts in the International Space Station (ISS) need to exercise rigorously for two hours each day to maintain their body functions. Still, their faces get rounder in space without gravity to pull blood and other bodily fluids downward. Then what will happen to the brain in microgravity if you stay for months? Research shows that the parts of the brain that control movement, balance, and body awareness physically adapt to microgravity, just as other parts of the body do. For a round-trip to Mars, it takes six to nine months for each one-way journey in microgravity and over a year in one-third gravity to wait for a launch window for Earth. For astronauts, it’ll be quite a challenge physically, cognitively, and mentally to live without gravity for a long time.

Japan is running out of royals. So why won’t it let women become emperor?

Before the current 126th emperor Naruhito took the throne in 2019, there were eight empresses in Japan’s 27-century-old imperial family. But in 1989, the Imperial House Law banned female emperors. Then in 1947, the imperial family was downsized to the immediate relatives of then Emperor Hirohito, abandoning 11 collateral branches. The current shortage of successors began from there because he had only two sons, one of whom had no children. Now, Emperor Naruhito is 66 years old and has just one daughter. His only brother is 60 and has two daughters and one son, who will turn 20 this September. Japan’s royal family members perform a variety of duties, such as attending state functions, public activities, and court ceremonies, but now they are done by fewer members because female members leave the royal family once they get married. Another serious issue is succession. There is only one male in the next generation of the current royal family. While the emperor's only child, Princess Aiko, is widely popular among Japanese citizens, conservative politicians and scholars dismiss the chance of creating an empress. So, how will the world’s longest royal family survive?

'Once it's gone, it's gone': How to future-proof your hearing

You know how noisy electrified music concerts and sporting events are. Also, a gasoline-powered leafblower, lawnmower, and buzzsaw are too noisy for unprotected ears. Surprisingly, fresh air from the car window on a highway is noisier than you might think. In addition, many people listen to music through headphones all the time without realizing how loud it is to their ears. All these unnaturally loud sounds bend or break tiny hairs in the ear, whose motion is translated into electrical impulses that our brain interprets as sound. Unfortunately, once these hairs are damaged, they cannot be fixed or reborn, and therefore, the loss becomes permanent. That’s why listening to music through headphones for a prolonged period of time, and every day, would impair hearing ability without realizing it until later in life. It’s not just your eyes but your ears, too, that could be damaged by the screen and headphones.

See if you can spot an AI deepfake with our test

Nowadays, photos taken by smartphones are usually edited or enhanced to some extent through intelligent systems to make them look clearer or more vibrant. AI deepfake technology can replace faces, manipulate facial expressions, and synthesize faces of individuals whose images have been shown on the web or shared online. The technology has become so advanced that deepfake photos are now hardly distinguishable. However, trained eyes can tell whether the images shown are real or fake in most cases, according to an international study conducted by Australian researchers. In the meantime, as AI is being trained with more data, it'll create more realistic deepfake images over time. Maybe only AI can distinguish real images from fake images.

Seven things you shouldn't do when eating in Italy

When in Rome, do as the Romans do, especially when it comes to what to eat and how to eat it.

Just like any other national or regional food, the culinary practices of Italian food are deeply tied to geography, history, and culture, and reflect the local environment and ingredients. Also, it is designed to be enjoyed in an orchestrated manner, starting with antipasto, followed by pasta, a main dish with seasonal vegetable side dishes, and dolce. Another important tip you want to know is that not all Italian food goes well together. For example, you do not want to sprinkle mountain-produced permesian over seafood. You also want to avoid ordering a rich, creamy cappuccino after lunch or dinner. Finally, expect your lunch or dinner at a restaurant to take hours because it is a social ritual. After all, you want to enjoy a meal rather than simply filling your stomach.

Sick of Earth? NASA is recruiting volunteers for a yearlong Moon and Mars simulation

Though it is not quite like flying to, living on, and returning from the red planet, you’ll experience what they are going to be like in the same space and environment. NASA is now recruiting volunteers who are willing to commit themselves to spending 14 months in a simulator with three others. The participants will spend several months inside a mock 60-square-meter spacecraft unit, move into a one-story, 84-square-meter facility to do on-Mars duties, and then go back to the spacecraft unit for the return journey. The mission crew will live on a Martian day, about 40 minutes longer than a day on Earth. Also, their diet is limited to space food and a few vegetables they grow in the simulator. They are expected to perform all scheduled tasks, exercises, and rests. What the participants will miss is Mars's gravity, which is only 38% of Earth’s, and the hundreds of days the mission will require to stay on Mars before the return journey. Can you maintain physical, mental, and emotional health in a confined environment with only three co-participants?

Most popular baby names for boys and girls in 2025 revealed

Nearly 90% of the UK’s 69.5 million population lives in England and Wales. There, 585,000 live babies were born last year. Some people might assume their popular names are like Charles, William, Harry, Edward, George, Tony, Gordon, or David for boys, and Camilla, Catherine, Sophie, Charlotte, Theresa, or Mary for girls, just like the UK’s royal families and PMs. In fact, Muhammad, Noa, and Leo are the top names for boys, and Olivia, Lily, and Amelia for girls, last year. Muhammad, also spelled Mohammed or Mohammad, is an Islamic name and a direct tribute to the founder of Islam. This Islamic name is so popular in the UK because the Muslim fertility rate is about twice as high as that of other Britons.

Why 'Asia's cleanest village' bans tourists on Sundays

Mawlynnong is a small village in the north-east of India near the border with Bangladesh. The village with a population of just 600 became famous for its cleanliness after it was named Asia’s cleanest village in 2003. It features flower-lined pathways, bamboo dustbins, and is free from single-use plastic. The village is maintained by its predominantly Christian villagers, young and old, many of whom do business with visitors. But on Sundays, they keep the village only for themselves to attend church and enjoy a peaceful day. Because it is a day off for everyone, they can also plan a family gathering, personal meeting, or community event without schedule conflicts. Do they lose a day of business every week? Since the Sunday closure is well-known, most visitors come on other days of the week. The cleanliness of the village seems to be sustained longer with the welfare of the villagers.

Ford rehires human engineers after AI fails to match quality checks

Founded in 1903, the Ford Motor Company is the second-largest American-based automaker, producing popular vehicles including the F-150 pickup, Explorer SUV, and iconic Mustang. In the last few years, the legendary automaker has introduced AI across its operations, including the quality-checking process. However, the company didn’t seem to have planned a smooth human-to-AI transition well, and the AI quality checker failed to live up to expectations. The management has learned that AI needs to learn sufficiently to perform its duties. The automaker has then rehired veteran technicians to train the machines that had taken over their jobs earlier. What will happen to them when the machines have learned enough knowledge and skills from them? When humanoid robots are deployed to human environments where safety is the #1 priority, they surely need to be trained properly and sufficiently before their introduction.

AI glasses are aiding cheating in exams. Test-obsessed Asia is ground zero

Ever since students started using AI tools like ChatGPT for academic writing, teachers have been struggling to find the right way for assessment.

The sites fighting to be removed from the UNESCO World Heritage List

UNESCO’s World Heritage List was brought forth to protect culturally and environmentally significant places in 1978. Since 12 sites were first inscribed on the list in 1978, it has grown to over 1,200 in 170 countries. In the beginning, the sites inscribed were monuments, archaeological sites, and buildings, but newly inscribed sites overlap with places where locals live, such as Vlkolínec in Slovakia and Ngorongoro Conservation Area in Tanzania. Once inscribed on the list and posted on SNSs, world heritage sites become popular tourist destinations, which helps the local economy and raises funds for conservation. However, when a site is overvisited by tourists and overinvested by businesses, its original value might be lost, and residents’ lives are disrupted. Some of them are now even calling for the removal of the site from the heritage list. The World Heritage List certainly authenticates the significance of the site, and SNSs amplify its popularity.

Bored at work? Let AI do the heavy lifting

As AI takes over entry-level tasks in many workplaces, requirements for entry positions, and even for veterans, are rapidly changing. While many entry-level jobs and repetitive tasks are being replaced by AI, humans are doing more productive, creative, or managerial tasks. They are now expected to undertake greater responsibilities faster and better by using AI, which is improving and evolving continuously and rapidly. Therefore, all workers, including newcomers or job starters, need to be competent in using AI and keep upskilling to be valuable office workers. One valued skill in today’s work environment is the ability to integrate AI into real work processes to produce better solutions. Another is the ability to use AI as an agent to improve the work quality and efficiency. For example, the effectiveness of an ad can be analyzed and summarized, and suggestions for improvement can be proposed by AI. Humans then give new directions and make judgments as to how to reach and move the target audience more. AI is indeed reshaping job requirements, but it is still humans who finally exercise soft skills, such as communication, collaboration, and face-to-face interaction, to be valuable in the workplace and for customers and clients.

Droughts are transforming the Turkish landscape with massive sinkholes

Located on the southwestern edge of the Central Anatolian Plateau, Konya was once the capital of the Seljuk Empire. It is now the agricultural capital of Turkey, producing about 10% of the country’s agricultural production, including water-thirsty crops like sugar beets and maize. Konya is located in a closed basin, and its water supply relies heavily on rapidly depleting groundwater due to excess extraction for farming. Approximately two-thirds of the 100,000 wells in the region are illegally created. Because of the drought, farmers are pumping more groundwater than it is naturally replenished. As a result, many hazardous sinkholes have appeared rapidly in recent years in the area, some are as large as more than 200 meters in diameter and 170 meters deep. Unless current farming practices are changed, more sinkholes will appear as a clear sign of depleting groundwater. Borrowing from the future for today’s needs is an acceptable practice as long as the debt is payable. Can they expect to have more rain?

Café Terrace at Night: Five details that unlock the genius of Van Gogh's original 'starry night'

Vincent van Gogh was a Dutch Post-Impressionist painter who created about 2,100 artworks before he took his own life in 1890 at the age of 37. To enjoy the sun and colors of Southeastern France, he arrived in Arles in February 1888 and stayed there for nearly 15 months. Seven months later, he created Café Terrace at Night with his first starry background. The iconic post-impressionist nocturnal art uses bold yellows, warm oranges, and deep cobalt blues but not black, evoking the vibrant, inviting energy of a bustling public gathering under the stars. The color contrast of the brilliant yellow light from the café and the dark blue sky appeals to viewers' eyes and impresses their minds. And there are other details that Van Gogh recreated an ordinary city square into a dreamlike mirage, including the colorful cobblestones, columns, chairs, the tower, and the stars.

uropean summers are getting brutally hot. So why is air conditioning so rare?

Under the searing and prolonged heat waves in June, temperatures reached or exceeded 40 degrees in many parts of Europe. France recorded its hottest day, with the highest temperature reaching 44 degrees, leaving dozens who sought relief in rivers and lakes drowned. While homes and buildings in southern European countries are heat-resistant with thick walls and small windows, those in northern Europe are built without heat in mind. Then why don’t they install air conditioners? Economically, ACs are expensive to run for Europeans whose electricity bills are relatively high. Also, while ACs make the rooms comfortable, their compressors outside make the building look ugly. Environmentally, ACs increase planet-heating pollution because they exhaust heated air to the outside. And if more fossil fuels are burned to run ACs, it will make it harder for Europe to reach the 2050 climate-neutral goal. However, as heatwaves become more frequent and prolonged, air conditioners may soon become a must-have home appliance in Europe, too.

How to exercise safely in hot weather

A sweat-inducing heat dome over 40 degrees covered much of Western Europe last month, forcing France to ban public Alcohol consumption. FIFA introduced a mandatory three-minute hydration break into each half during the 2026 World Cup held in North America. As this summer in the Northern Hemisphere isn’t going to be much cooler than last year, how should you keep exercising outdoors? In hot conditions, your body tries to cool itself by sweating and diverting blood towards the skin, which puts extra strain on your heart and could lead to heat exhaustion, or, in the worst case, heat stroke. Since quitting exercise could put your long-term health at risk, you need to adopt practical methods to maintain physical activity, such as choosing the time and place to exercise, adjusting the menu depending on the temperature and humidity, pre-cooling or cooling down smartly, and consulting your body when to rest or stop. One thing you want to avoid is pushing yourself to the limit in the heat. After all, you’re exercising for your long-term health.

Rivers set free: Why countries are tearing down hundreds of dams

Rivers naturally experience seasonal fluctuations, flooding during heavy rain or melting snow, and drying up during droughts. Dams are built to prevent floods, generate hydropower, and manage water flow and supply for farming, daily life, and navigation. In Europe, there are as many as 1.2 million water barriers, such as dams and weirs, but many of them have been removed recently to restore the environment and ecosystems. In fact, Sweden, Finland, and Spain each removed more than 100 barriers in 2025 alone. If a river is blocked, some fish species, such as salmon, face difficulty reaching upstream habitats for reproduction, and ecosystems are fragmented by barriers. Also, water in reservoirs can be lost faster through evaporation. But removing such barriers is no easy task, as it takes years of environmental assessments, engineering studies, and public consensus. In the meantime, are they prepared for more extreme rains, severe drought, and rising temperatures that will melt ice and snow faster without dams?

Qantas locks in launch date for Sydney-London nonstop flights as it debuts the custom jet designed for the trip

Opened in 1920, Sydney Airport (SYD) is the busiest airport in Australia, serving more than 40 million passengers, and the main hub for Qantas, Australia’s flag carrier. Since Australia sits on an isolated continent in the southern hemisphere, flight distances from SYD to major cities in other continents are quite extensive: 6,300 km to Singapore, 10,400 km to Delhi, 16,000 km to New York, and 17,000 to London.  In 1947, Qantas's first direct flight service from Sydney to London, the Kangaroo route, carried 29 passengers with stops in Darwin, Singapore, Calcutta, Karachi, Cairo, Tripoli, and Rome, flying 55 hours in four days. Today, it takes more than 24 hours to reach London with a stopover in Singapore. Now, starting from October next year, the airline is set to start a non-stop service between the two cities, and also to New York. The Airbus A350-1000ULR (Ultra-Long-Range) will fly 22 hours with 238 passengers on board in 3 first-class suites, 52 business-class suites, 40 premium economy seats, and 140 economy seats. The flight will save a stopover and about two hours, but will probably cost more because it’s a non-stop service. Special seats, services, and amenities will be provided for the passengers to survive this day-long flight from gate to gate. Also, crew members will have to work and rest even longer on the aircraft. Since there are several one-stop flights between the two cities, the choice is yours.

Thousands of baby seals died on two remote sub-Antarctic islands. Scientists now think they know why

On remote sub-Antarctic islands about 4,000 kilometers southwest of Australia, thousands of carcasses of seal pups, penguins, and seabirds were left. In one area, nearly all seal pups were dead. It was found that the cause of the devastating deaths of the sea mammals and birds was H5 bird flu, which had likely been transferred through migratory birds from other sub-Antarctic islands 1,800 km away. The H5 bird flu, specifically the highly pathogenic H5N1 strain, is a contagious, deadly disease currently widespread among wild birds, commercial poultry, and dairy cattle. While the public health risk to humans remains low, infected birds and animals display severe symptoms and then die. When H5 bird flu is detected on a chicken farm, it is put under strict quarantine, its entire flock is culled, and the farm undergoes extensive cleaning and disinfection. Last month, a wild migratory brown skua was found positive for the H5 bird flu in Western Australia, the first case on the continent. People in Australia are now advised not to touch sick or dead birds or animals. Watch out not only for sharks but also for seabirds on Australian shores.

Satellite images show 10 places where water is disappearing globally

Caused primarily by human activities and climatic variations, desertification is the degradation of land in arid, semi-arid, and dry sub-humid areas. A drought is a prolonged period of unusually dry weather with very little or no rain over an extended period. Both slowly impact ecosystems, agriculture, and water supplies. To raise public awareness about desertification and drought and promote action to restore degraded land, the UN marked June 17 as the World Day to Combat Desertification and Drought three decades ago. Over the period, however, the world has lost a significant amount of freshwater. The South Aral Sea in northwestern Uzbekistan and Lake Urmia in northwestern Iran have both shrunk by more than 90%, exposing the former lakebed. Lake Mead, the US’s largest reservoir on the Colorado River, has shown a dramatic decline due to prolonged drought, rising temperatures, and excess water usage. Also, lakes in Africa and South America, and South America’s second-longest river, have shown drastic shrinkage. As the world’s population increases and temperatures rise, more water is needed for drinking, farming, and industry. Will we then depend more on recycled or desalinated water instead of fresh water?

Why moving about is key for children's health - and happiness

Gone are the days when children rushed to go out to climb a tree, run and jump around, or play tag in their free time. Nowadays, instead, they play online games, watch videos, or scroll screens indoors whenever they find time, moving only their fingers and eyeballs. Once children get used to a sedentary life, they tend to be less physically active in their future and visit the doctor more often in adulthood. Also, studies find that physically active children show better mental health, educational achievements, and cognitive performance. What parents and carers can do to help children is encourage them to do more physical activity, not just by words but by playing sports, running, or walking together, or enrolling them in sports clubs or events. Schools can dedicate some time daily to have students do physical activity during recess or lunch break instead of leaving them with their smartphones. As smartphones have become intimate with children’s lives, moving bodies is essential for children’s health, wellbeing, and future.

Tricycle ambulances are saving lives in Ghana

In Ghana, there are only 356 ambulances for a population of 35 million, approximately one ambulance per 10,000 people. However, hundreds of thousands of people in rural areas do not have access to ambulance services. There, maternal mortality remains comparatively high, with 234 deaths per 100,000 live births, 14 times higher than in the US. Most of these deaths occur in rural areas, where access to hospitals is limited or none. Then a non-profit called Moving Health came up with a practical and economical vehicle for about-to-be mothers: a tricycle ambulance. It is powered by a motorcycle engine and equipped with a stretcher, a seat for a carer, basic life support, and emergency birthing kits. It costs only $7,000, much cheaper compared with a full-spec ambulance that usually costs at least $75,000. The organization has placed 31 tricycle ambulances in five districts so far, serving more than 230,000 people, who otherwise have no access to an ambulance. Tricycle ambulances can serve in rural areas as they are engineered to drive narrow, rough roads where four-wheel ambulances cannot. Just like three-wheel tuk-tuks are transporting many passengers in Asia, tricycle ambulances may become popular emergency vehicles in Africa.

Instant noodles have a bad reputation — but the world still can’t get enough of them

Invented by a Japanese businessman in 1958 to fill hungry stomachs, instant noodles are precooked and dehydrated noodles that are quickly prepared just by adding hot water. Because of their palatability, convenience, long shelf life, and affordability, today about 120 billion servings are consumed worldwide. China consumes the most, with more than 40 billion servings annually, followed by Indonesia’s 15 billion and India’s 8 billion. On a per-person basis, Vietnamese and South Koreans eat the most, about 80 servings per year. Because instant noodles are affordable and satisfying for the tongue and stomach because of their alluring combination of salt, sugar, fat, and carbs, they make eaters addicted. They are also ultra-processed foods, such as snacks, sweets, and frozen ready-to-eat meals. Even though instant noodles are comfort food and readily available anywhere around the world, you want to avoid consuming such highly processed food too often for your health.

AI is sparking a jobs boom — just not for newbies

As AI takes more human roles, thousands of jobs, such as repetitive, structured, predictable tasks, such as data entry, telemarketing, customer service, coding, and administrative positions, have been eliminated in the US. Accordingly, there are significantly fewer job openings for these entry-level jobs, which are suitable for new graduates to start their careers. As of March, over 5% of recent college graduates were unemployed, while the overall unemployment rate stood at 4.2%. Upskilling is one way for job seekers to qualify for remaining job opportunities, but AI is also upgrading while they are learning new skills. As for US employers, instead of growing talent through jobs, they are looking for senior-level talent who can manage AI and teams around the fast-moving world, and they are competing to hire people from the same small pool of talent. But this eliminates not only young people’s job opportunities but also their chance to bloom in the future. What seems essential for businesses might not be just replacing jobs with AI but improving and growing with AI.

Costs, careers and choice: Why Indians are having fewer children

The total fertility rate (TFR) is the average number of children a woman would have over her lifetime. Though it had been declining gradually over decades, India’s TFR was still above 3.0 births per woman in the 2000s. Recently, however, it has fallen below 2.1, the replacement level to keep the population stable. Even though the figure remains higher than in other developed countries, the downward trend of the fertility rate reflects fundamental changes in India’s society. The drop in TFR in developed communities such as Delhi and Bengaluru, and Southern states with good health and education systems like Kerala, is as significant as in another populous country, China. In the meantime, in poorer states like Bihar and Uttar Pradesh, with lower education levels and higher infant mortality rates, fertility rates are twice as high as those in high-income states. Better education, career development, lower child mortality rates, changes in family values, along with inflation, seem to have led India’s women to choose to have fewer or no children. The world’s most populous country is now facing the same problem as other developed countries.

Morocco’s answer to drought is in the ocean. Could more of Africa follow its lead?

The world is now using more water than nature provides by rain and snow, and as a result, rivers and lakes are shrinking, wetlands are drying up, and aquifers are declining. Morocco spans from the Atlantic Ocean to mountainous areas and the Sahara Desert. As drought occurs more frequently and for longer, the country can no longer rely on rainfall and dam inflows. So, the country with a population of 37 million launched a project to provide fresh water from the Atlantic to coastal cities while using dam water and rainfall for inland areas. The project includes building desalination plants, dams, wastewater reuse, and water pipelines. The energy-intensive desalination plants are powered by eco-friendly wind and solar power. Economically, desalinated water will boost agricultural outputs and secure farming jobs, which account for a third of the nation’s workforce. However, they also produce high-salt-concentration brine with chemical residues, which could damage marine ecosystems when discharged back into the ocean. Currently, over 20,000 desalination plants are in operation around the world, most of which are fossil-fuel-powered and in the Middle East. Morocco wants its water project to be shared by other water-stricken African countries.

Swiss voters reject 10 million population cap

While Switzerland’s total fertility rate sits around 1.3, well below the 2.1 replacement rate, its population has grown by nearly 30% in the last three decades to 9.1 million. The driver of the population growth is foreign residents, who now account for as much as 27% of the nation’s population. They contribute significantly to the nation’s economy and society, particularly in tourism, hospitals, and care homes. For example, about half of hotel workers are now immigrants. While they become a much-needed workforce immediately, the rapid increase in the adult population has put strain on transport, housing, and the environment. Recently, a proposal was made by a right-wing party to cap the nation’s population at 10 million. At the direct vote on June 14, 55% of the voters rejected the proposal and 45% supported the population limit. Politicians and business leaders are particularly relieved by the result because they want to keep the country’s commitment to Europe’s free movement of people, a crucial requirement to be part of Europe’s single market. But the 5% gap in the vote might change to the other side depending on social stability, economic pressure, and living conditions.

Maasai women turn drought into income through fodder farming in Tanzania

Maasai people live in Kenya and northern Tanzania. They traditionally make their living by herding livestock, mainly cattle, goats, and sheep. When drought hit the region, they would lose their livestock. Traditionally, Maasai women are responsible not only for managing domestic duties and raising children but also for building homes and milking livestock. Recently, they came up with drought-resistant livestock fodder, which not only feeds their livestock but also generates money. It is part of the climate-adaptation initiatives that are coordinated by the Pastoral Women’s Council (PWC), a women-led membership organization that serves over 450,000 Maasai pastoralists, whose lives and wealth mostly rely on their animals. When climate change accelerates, people of all kinds and ages need to adapt their living to more severe extreme weather conditions.

Why have World Cup hydration breaks attracted criticism? It's the ads.

While basketball and American football are divided into four 10-to-15-minute quarters, a soccer/football match is split into two 45-minute halves, excluding the stoppage time added by the referee for injuries or substitutions. Now, since the 2026 World Cup games are being hosted in Canada, the USA, and Mexico, game conditions vary widely. FIFA, then, introduced mandatory 3-minute hydration breaks taken 22 minutes into each half for all of the 2026 World Cup matches, to ensure equal conditions for all teams amid dangerous heat. While the additional mandatory breaks hydrate and recharge the players, they disrupt the natural flow and momentum of matches. Fans aren’t necessarily happy with the two disruptions in the middle of the game and the extended game time. In the meantime, the hydrogen breaks bring economic benefits. Since each of the 104 matches has two 3-minute extra ad times, there will be a total of 832 30-sec commercial slots, which will generate substantial revenue for the broadcasters and then for FIFA.

El Niño is here and rapidly strengthening. Here’s what it means for your weather

El Niño conditions are now underway in the tropical Pacific, with sea surface temperatures having risen sharply in recent months, according to the US National Oceanic and Atmospheric Administration (NOAA). El Niño involves the transfer of a large amount of heat energy from the ocean to the atmosphere, which boosts global average surface temperatures, leading to extreme weather conditions, such as heat waves, flooding, and droughts, depending on the location. It occurs every two to seven years and lasts for about a year, but this one is predicted to be stronger than previous super El Niño events in 2015-16, 1997-98, and 1982-83. Since global average surface temperatures have increased to a record high due to human-caused warming from fossil fuel burning, 2027 will likely be even hotter than the previous record in 2024. Humans have learned to predict climate change, like global warming and El Niño. Are we ready for a hotter, drier, or wetter climate?

The Netherlands vs the sea: The race to hold back rising waters

About a quarter of the Netherlands lies below sea level, and major coastal cities  Rotterdam, the largest seaport in Europe, sits at -4 meters, and Amsterdam, the capital, at -2 meters. But unlike New Orleans (Vol.5166), the low-lying nation has long been protected by massive storm-surge barriers called the Delta Works for decades from the rising levels of the North Sea and overflowing rivers. Completed in 1997, the 1,000km long protective system consists of dams, dikes, levees, sluices, and pumps. However, as sea levels rise faster and storms become fiercer, the protective system is feared to become unsustainable. The country is already spending about 1% of its GDP annually on building new structures and maintenance and operation of the existing system. It took more than 1,800 lives in the 1853 North Sea Flood to initiate the Delta Works project. How will the Netherlands cope with the rising danger?

Iran’s lakes are vanishing: Satellite images show a deepening water crisis

Iran has hundreds of dams to generate electricity and store water, yet its 92 million residents are facing severe water shortages. More than 30,000 of the country’s 69,000 villages have been abandoned so far due to water shortages. Years of drought, declining rainfall, and unsustainable water use have depleted reservoirs, rivers, and groundwater reserves. For example, Lake Urmia, the largest saltwater lake in the Middle East, has shrunk to less than 10% of its former size since the 1990s. About 90% of the water is used for agriculture, but much of the extracted water doesn’t reach crops because of inefficient irrigation systems. Iran has plenty of oil to export to buy weapons, but not enough water to sustain its farming, industry, and population. It has been at war with the US and Israel for its nuclear weaponization effort, and is putting most of its resources and efforts into firing missiles and flying drones. But which might deplete first, weapons or water?

Rising seas will swallow New Orleans. People need to start relocating now, scientists say

Some coastal regions in the world have already started relocating due to sea level rise and sinking land. Tuvalu, a Pacific island nation, is organizing the world’s first planned migration of the entire country to Australia. Jakarta, Indonesia, is relocating the nation’s administrative capital functions to another island. The USA is no exception. New Orleans, famous for its lively jazz, vibrant Creole culture, and historic French Quarter, sits in a low-lying basin, mostly below sea level. It is surrounded by extensive, highly vulnerable wetlands that are crucial for buffering storm surges, but they are rapidly disappearing due to human activity, land subsidence, and rising sea levels. About 75% of its remaining wetlands are predicted to be lost, and the inland could retreat by as far as 100 km. New Orleans has already lost about a quarter of its population since the 2005 Hurricane Katrina, which submerged 80% of the city and killed nearly 1,400 people. As the city’s residents move out, tax revenues, public services, and home values decline, and as a result, empty or abandoned properties will increase. As protective wetlands disappear, land sinks further, and sea level rises, New Orleans is facing an existential challenge, as critical and urgent as that of the Pacific Islands.

Siesta then fiesta: Enjoy Europe like the locals

Seville, Athens, and Rome. One thing common about these European popular tourist destinations is scorching summer heat. This year, Europe’s heatwave season had already started in late May, marking an all-time May record in London and Budapest, knocking out tennis players at the French Open, and killing over 100 people in heat-related deaths in Spain. If you’re traveling to Europe this summer with an ordinary 9 am-6 pm outdoor itinerary, you’ll be baked just like other tourists. So, instead of going out during the heat hours, how about visiting outdoor tourist destinations early in the morning, staying indoors and taking a siesta in the afternoon, and going out again after sunset to enjoy nighttime tourism? Locals spend the summer days by this work-siesta-work and fiesta schedule to avoid the summer heat while working and enjoying just like in other seasons. In fact, people in Italy and Spain usually have dinner around 9 pm and enjoy after-dinner activities until after midnight. If your body clock is already confused by the jet lag, it may be easier to adjust it not to the local time but to the local customs.

In the lowest place on Earth, a sea is rapidly dying — and no one can agree how to save it

Located on the border between Jordan and Israel, the Dead Sea is an inland salt lake sitting at about 430 meters below sea level, the lowest exposed point on Earth's surface. As the salinity of the lake is about 34%, roughly 10 times saltier than usual ocean water, your body floats easily in the water. However, as climate change has made droughts fiercer and rainfall rarer, the water level has dropped. Also, over the past decades, excess amount of water has been extracted from the Jordan River for increasing population, crops, and livestock, which has significantly reduced the water flow and shrunk the Dead Sea. As a result, the sea level has been dropping by about one meter annually, and as a result, the surface area has shrunk by approximately one-third. Also, the salt water has become too salty to dissolve salt anymore, causing the undissolved salt to form solid crystals and natural salt sculptures. It is an environmental disaster in slow motion, which requires immediate attention and action. Unfortunately, the surrounding countries, Israel and Jordan, are too busy dealing with regional conflicts and extracting minerals from the brine to deal with the clear and present environmental danger.

Brain freeze? Ice cream headaches can reveal a surprising amount about your health

When you sip, lick, or bite a cold substance, such as an ice cube, shaved ice, or ice cream, you might feel an acute ache in your forehead. This cold-stimulus headache occurs when the roof of the mouth or back of the throat is cooled so rapidly that it shrinks the blood vessels, and then the shrunk vessels are forced to swell back up again to restore blood flow. This rapid change in the blood flow activates pain receptors and sends signals to the brain, but the brain misinterprets them as coming from the forehead rather than the mouth. That’s why your forehead hurts but not your tongue. It is easily avoidable if you take a little more time to eat or drink cold food or drinks. But some people still experience a more severe headache than others. Researchers think this blood vessel shrinkage seems to run in families. Do your parents have ice cream headaches, too? Also, those who have migraine tend to experience this kind of headache when they eat cold stuff. So, if you feel pain in your brain or forehead when you eat ice cream even if you’ve eaten it slowly, you may want to try the same treatment as for migraine.

Why America’s rich keep getting richer

In the “K-shaped economy”, the upper arm of the letter “K” represents the wealthy while the lower arm shows lower-to-middle-income families. In the last three years in the US, the top 1% earners increased their cumulative real net worth by 30%, the next 19% earners gained 20%, and the next 20%, classified as the upper middle group, enjoyed about an 18% increase (Vol 5152), while the middle 40% and bottom 20% had less than a 15% gain. What made the gap wider between those who gained wealth more and less is housing, stocks, and inflation. Even though the S&P 500, the benchmark market index, has gained 86% over the last three years, about three-quarters of America’s stocks are owned by the top 20% earners. As for housing, over half of mortgages belong to the top 20%, whose property values have seen steep increases in the last few years. In the meantime, recent inflation in food, energy, and gas prices, in particular, hit the middle 40% and bottom 20% of income groups harder because they spend a higher proportion of their income on those daily necessities. Once dreamed of by middle-income households were cars and houses, which are now getting out of their reach. How will AI affect the wealth gap for Americans?

The FIFA World Cup kicks off next week in the US, Canada, and Mexico, and millions of fans will scream germs into the air of very crowded stadiums. Also, summer vacationers are traveling around and interacting with others in many ways. In the meantime, the hantavirus outbreak on a Dutch cruise ship in April infected 13 on board and killed three.

Contagious diseases can be easily transmitted from one person (or animal) to another through various routes, including airborne/respiratory droplets, physical contact, or fecally or orally contaminated surfaces. One of the most worrisome contagious viruses is measles, whose particles can stay in the air for up to two hours. It is much more contagious than the flu or COVID-19, as a single infected individual could pass the virus to between 12 and 18 people. The problem is that even though it can be contained by a simple vaccine, vaccination rates for measles are falling in many countries, including the World Cup host countries.

Is 'out of control' US tipping culture spreading overseas?

In the US, tipping is a standard practice for services such as restaurants, taxis and rideshares, doormen and bellboys, and delivery services. Among these, servers at restaurants depend most of their income on tips from their customers because their minimum hourly wage is set significantly lower than the federal minimum wage. The expected restaurant tip in the US was 10% to 15% of the bill in the mid to late 20th century, but it has risen to 18% or higher today, partly due to pre-programmed electronic payment machines that often suggest 18%, 20%, 22%, and 25%. In large cities like New York, Chicago, and Los Angeles, a 20% tip is mostly expected. Tipping/gratuity is a unique practice in the USA, and it is not expected in most other countries. However, when American travelers dine in restaurants abroad, they often leave tips for their servers. This has made serving staff expect tips from other customers, too, which makes locals annoyed. Another influencer of tipping practice is rideshare services, like Uber, which also show tipping options in other countries where they operate. If you travel abroad, you may want to ask AI if you should leave tips, where, to whom, and how much in advance.

However, you cannot expect free tap water at a restaurant there. Instead, you are expected to order bottled mineral water, choosing between sparkling or still. And a recent ruling by the Italian Supreme Court allowed hospitality venues in Italy to refuse requests for tap water and serve only sealed, bottled water at the table. The ruling was made in response to a claim by a woman who was refused to serve tap water at the restaurant of a five-star hotel in a ski resort. She was offered an eight-dollar bottle of mineral water when she asked for tap water. She argued that water is a natural resource and a universal human right. In Italy, however, laws and regulations do not mandate restaurants to provide free tap water to guests, and therefore, it is up to individual venues to serve tap water to their guests. When in Rome, do as the Romans do, a timeless proverb says, but the woman was visiting from Rome.

We’re living in the ‘premium economy’ economy

Premium economy is an airline cabin class situated between economy and business class, offering upgraded comfort with wider seats, extra legroom, enhanced dining options, and priority airport services, at 30% to 60% higher prices than economy class tickets. Recently, airlines have been adding more premium economy seats for passengers who are willing to pay more for better, but not thrice or more for business class. This move reflects the increasing number of upper-middle-class consumers in the US economy, whose annual household income ranges from $133,000 to $400,000. They cannot afford to buy a house whose values soared after the pandemic and inflation, but they earn higher wages that they can use for more comfortable travel experiences and higher-quality groceries. Full-service carriers and retailers like United Airlines and Walmart are generating more profits from these valued customers, while budget airlines and discount retailers are struggling to run their businesses, including the recently bankrupted Spirit Airlines. McDonald’s or Starbucks may be an economical option for these upper-middle-class consumers, but they are premium food and drink options for many Americans who are struggling to make ends meet due to soaring commodity, gas, and energy prices.

Why did T. rex have tiny arms? A new study may finally have the answer

The Tyrannosaurus rex (T. rex) was one of the largest and most fearsome terrestrial carnivores that lived between 68 and 66 million years ago. An adult T. rex grew up to 12 meters in length, stood about 3.6 meters tall, and weighed six to nine tons. The unique, iconic feature of the carnivore was its massive, heavily reinforced skull, which was used as its primary weapon. As herbivorous dinosaurs grew larger to deter predators, predatory dinosaurs faced immense evolutionary pressure to grow larger and stronger to hunt them. So, T. rex and some other carnivores invested their most energy resources in growing a larger head, stronger skull, and sharper teeth. The trade-off was their forearms, which did not play any vital role in their survival. As a result, those non-essential parts of their body shrank over time. Researchers believe that was why the T. rex had disproportionately short forearms. Evolution seems to have grown T. rex’s skull stronger and larger while shrinking its forearms, and made the land carnivore like a giant land shark.

This paint could cool your home and harvest water from the air

Cities are becoming hotter and hotter as concrete and rooftops absorb the sun’s energy, causing the urban heat island effect. If the sun’s energy is reflected, urban temperatures might be reduced during the summer. Do paints help increase the reflection of the sun’s energy? Total Solar Reflectance (TSR) measures how much sunlight a paint reflects. For example, black paint typically reflects less than 10% of sunlight, or absorbs 90% or more of the sun’s energy, while white paint reflects around 70% to 80% of incoming sunlight. Naturally, a white-painted building is cooler than a black-painted one under the sizzling summer sun. Now, an Australian startup has developed a special coating that reflects up to 96% of incoming sunlight, which keeps the roof surfaces as much as 6 degrees Celsius cooler than the surrounding air. If more rooftops are painted with this nanoengineered special coating, the urban heat island effect will be eased without costing any environmental burden. Also, if the surface temperature is lower than the surrounding temperature, moisture in the air is condensed on the surface, like water is formed on the outside of a cold glass. Once the water is collected, it can be used as a supplemental water source for the toilet or shower. Passive radiative cooling, a technology that cools surfaces by reflecting sunlight and radiating trapped heat outward into the cold sink of deep space, is expected to play a vital role in cooling cities while reducing carbon emissions.

'Everest Man' and 'Mountain Queen' break own records scaling world's tallest peak

This season, as many as 500 alpinists were permitted to climb Mount Everest from Nepal. Unfortunately, a massive block of glacial ice hindered the route to the summit and kept alpinists waiting nearly two weeks at the base camp. On May 13, the climbing route to the summit was officially cleared, and they started climbing the mountain. Among them was a renowned Nepali mountain guide, Kami Rita Sherpa, who broke his own record for scaling the 8,849-meter summit for the 32nd time. The 56-year-old mountain guide, known as the “Everest Man”, first scaled the peak in 1994 and has reached the summit almost every year. On the same day, a 52-year-old Lhakpa Sherpa, known as “Mountain Queen”, scaled the summit for her 11th time, breaking her own record for the most ascents by a female climber. A few days later, on the 20th, a record 274 climbers scaled Mount Everest from the south side. The world’s highest summit granted three records to climbers this season.

Why Canada is seeing its biggest military recruitment surge in 30 years

Despite its massive geographic size, Canada has a relatively small population of just around 41 million. While having the longest border and coastline in the world, Canada has only about 68,000 active and 32,000 reserve military personnel. Even though the Canada-US border is the world’s longest land border, neither country protects its border against the other because they are NATO allies. And Canada has been relying on the US military power against its other neighbor, Russia. However, Russia’s invasion of Ukraine in 2022 and Trump’s reference to Canada as the 51st state were wake-up calls for Canada’s national security. Last year, applications to the Canadian Armed Forces nearly doubled to 40,000 from the previous year. Also, Canada increased its military spending to 2% of its GDP last year, even though it is far short of NATO’s 5% target. Canada needs to raise pay for its military personnel, expand its troop size, and modernize weapons, equipment, and facilities to live up to the new reality.
