The self-drive tuk-tuks transforming travel in Sri Lanka

A tuk-tuk is a three-wheeled taxi popular in Southeast and South Asia, especially in Thailand and India. Tuk-tuks are widely used as taxis in urban areas as a conventional and economical transport for residents and tourists. In those places, thanks to the smartphone map, motorcycle rental is becoming popular among foreign tourists. Then what about renting a tuk-tuk? It allows you to travel and stop wherever and whenever you want for yourself, and maybe your travel companion. Such a service became available in Sri Lanka. Just like renting your spare room or apartment, some tuk-tuk owners are renting their three-wheel vehicles when they aren’t in use. You’ll need an international driving permit for booking, so that the renter can organize a local driving permit. Once you book a tuk-tuk online like a car rental, your tuk-tuk will come to your hotel. After getting a brief driving lesson, off you go!  

You may be hailed by other tourists for a ride, too. What an extraordinary experience!

Read the article about how this new service emerged in Sri Lanka.

She left her home in California to live on a cruise ship for 15 years

Villa Vie Odyssey is a 24,000-ton, 200-meter-long residential cruise ship where people can live aboard and travel around the world. Unlike ordinary cruise ships that sail passengers for days, weeks, or months, she accommodates just hundreds of “residents” who purchased their cabins and take them to various destinations around the world for as long as 15 years. The residents purchase their cabin like a condominium and then pay monthly fees for food and drinks, Wi-Fi, medical visits, weekly housekeeping, and bi-weekly laundry service. They can enjoy a continuous 3.5-year journey around the world while engaging with the other 500 or so residents on board. Some residents stay on the ship just for months, while others intend to live on board until the end of the voyage. Once onboard, you can enjoy watching the ocean and sky, feeling the ocean breeze, and bathing in the sunlight on the deck while checking what the next stop will be like. It may be more vibrant and entertaining than living alone in a house or a quiet care home on the ground. Also, if you are a remote worker, living on a residential cruise ship is just like renting a private, full-service office at sea. Since housing prices have soared in major markets, buying a cabin on a residential cruise ship might be a good option.

BMI is B-A-D, a new study suggests. Here’s a better way to measure weight

Body Mass Index (BMI) is a value from the mass and height of a person, which is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m². A BMI between 25 and 29.9 is considered overweight, and a BMI greater than 30 is considered obese. However, since BMI doesn’t account for body composition, like muscle, fat, or bone. So, someone with a high percentage of body fat could have the same BMI as a person whose height and weight are the same but very muscular. Also, BMI neither distinguishes between fat around organs and under the skin nor age, sex, or ethnicity. In order to provide person-specific health advice, Bioelectrical Impedance Analysis (BIA) measures the individual’s body fat, lean muscle, and water weight by using undetectable electric currents. With such information, medical or health experts can give more specific, tailor-made suggestions to improve your health.

Will a dice-playing robot eventually make you tea and do your dishes?

For many years, robots have been working in factories to do tasks programmed, such as attaching parts, drilling holes, and moving things. Recently, robots have been used in warehouses and distribution centers to load and unload trucks, move pallets, and pick and pack items. Some of them use sensors, AI, and machine learning to adapt to changing environments and requirements. Robots with embodied AI can see, sense, recognize things around them, and act accordingly to changing situations. Then, how soon will we see robots at home to do or help with household chores, look after babies, or assist seniors? Since home environments vary widely and change quickly, it is difficult to collect enough data to pretrain robots to perform tasks in such dynamic environments that people live in. However, even though today’s AI robots are still years away from being able to perform household tasks as flexibly and safely as required, they can learn quickly and better in the coming years. Imagine that AI robots were newborns. It would be faster for them to become capable of performing household tasks than human newborns.

How China made electric vehicles mainstream

China is the world’s largest automobile and EV country. Over 30 million new cars were sold in 2024 alone, more than the combined sales of the US and Europe. Among the new cars sold that year, over six million were battery-only vehicles (BEVs) and around 4.5 million were plug-in hybrid vehicles (PHVs). Combined, about 10 million electric vehicles, more than the EV sales in all the other countries combined. While other developed countries are seeing slower EV sales in recent years, China’s EV sales are growing fast. In fact, German, US, and Japanese automakers have somehow slowed down their EV sales projections. How has China become the leading EV country in the world? The price is one thing. The price tags of entry-level EVs are as low as those of conventional gasoline-powered vehicles. Also, government subsidies and incentives for EV and battery manufacturers and charging stations are quite substantial. In addition, registration and running costs are both much cheaper for EVs than those of conventional vehicles. Government’s strategies, commitment, incentives, and subsidies are all there in China to develop the industry in just a decade or so. The fast-growing industry is facing an overcapacity problem.

North Korea just opened a beach resort for 20,000 people. But who will visit?

Started in 1998, North Korea allowed South Korean tourists to visit Mount Kumgang, a 1,638- high mountain on the east coast of the country. Hundreds of thousands of tourists visited there each year until it was closed in 2008 when a South Korean tourist was shot in a restricted military zone. Last month, the secretive authoritarian country opened a new beach resort, the Wonsan-Kalma Coastal Tourist Zone, that is designed to welcome foreign visitors. The supreme leader Kim Jong-Un himself appeared at the inauguration event with his family and cut the ribbon. The Russian ambassador and staff also attended the ceremony to show their friendship with one of their remaining few allies. Though the resort is intended to earn foreign currencies, only a limited number of Russian tour groups are granted permission to visit the beach resort at the moment. Even though this newly opened resort looks no different from other beach resorts in the world, curious travellers might be interested in spending time and enjoying the services in one of the most secretive countries in the world.

More than a third of this country’s population has applied to relocate

Located about midway between Australia and Hawaii, Tuvalu is an island country in the Polynesian subregion of the Pacific Ocean. Around 10,000 people live in the land areas of only 26 km² on three reef islands and six atolls. Tuvalu’s average elevation is just two meters above sea level, and the highest elevation is only 4.6 meters. As sea level rises, the island nation is predicted to become uninhabitable by the end of the century. When Australia opened a window for Tuvalians to apply for 280 permanent residency visas in June, over 4,000 Tuvalians applied for the visa scheme. The winners will be chosen by a random ballot in the next six months. Tuvalu is now trying to recreate everything they have, land, history, culture, and governmental functions, into a digital space. Also, Australia has committed to recognizing Tuvalu as an independent sovereign country even after its land disappears into the sea. But will all the residents be relocated to other places in time?

South Korea banned dog meat. So what happens to the dogs?

Dog meat is consumed in several countries, including Vietnam, Indonesia, Cambodia, China, and South Korea. However, it has become less common in South Korea. According to a 2020 survey, over 80% of South Koreans had never eaten dog meat, and a government poll in 2024 found only 8% of respondents had eaten dog meat in the prior 12 months. So, in January 2024, the South Korean government passed a law banning the sale and production of dog meat, which will become effective in 2027 after a three-year grace period. If dog breeders stopped producing dogs for meat immediately, the number of dogs for meat would have gradually decreased, and would be zero when the trade is prohibited. However, most dog farmers have to make their living with dogs and cling to the business until the very end. According to government estimates, there are still nearly half a million dogs in dog farms. Since most of them are medium to large breeds, it is difficult to find their foster families in South Korea, where housing prices have soared in recent years. Also, rescue shelters are already overcrowded. Some are exported to other countries like Canada or the US, where larger dogs are popular as pets. But unless their homes are found, many of those dogs might be euthanized, instead of being eaten. Only 18 months left before the grace period ends.

The Eiffel Tower is closed to tourists due to searing heat. Here’s why it’s happening

Heat waves have become more frequent, intense, and longer because of climate change caused by humans, and Europe is warming faster than any other continent. In Spain, the average temperature in June surpassed the normal average for July and August. The UK, where fewer than 5% of homes are equipped with air conditioning, recorded its second warmest June since records began in 1884. At the Wimbledon tennis tournament, the players had to not only cope with their opponents but also struggle with the heat on the court. In Portugal, 46.6 degrees Celsius was recorded, the record-high temperature for June. In France, the Eiffel Tower summit was closed to tourists on June 30 and July 1 due to due to the searing heat. Also, the heat wave caused wildfires in Turkey, forcing 50,000 people to evacuate.

Dear MEL Topic Readers,

What does hot weather do to the body?

It’s summer in the northern hemisphere. Summer is becoming longer and more severe with higher temperatures and heat waves of over 40 °C. Can our bodies withstand such heat? Our bodies function best at a core temperature of about 37 °C. When the outside temperature rises, our bodies try to regulate body temperature by opening up blood vessels, which leads to lower blood pressure and makes the heart work harder to pump blood throughout the body. Also, as we sweat, our bodies lose fluids and salt disproportionally, so that their balance changes. As a result, we may feel dizziness, nausea, fainting, muscle cramps, and or headaches, typical symptoms of heat exhaustion. If you feel any of such symptoms in the heat, you should cool your body and skin, lie down, drink a lot of water or rehydration drinks. But if someone doesn’t recover from heat exhaustion within half an hour, feels confused or nauseous, vomits, stops sweating, experiences a high temperature over 40°C, or loses consciousness, the person is likely suffering from heatstroke and needs medical emergency. Since the climate is changing faster than how much our bodies can adapt, we need to adapt our lifestyles and activities to the heat.

Is an apple a day really good for your health?

"An apple a day keeps the doctor away" is a well-known English proverb, but is it true? Like any other fruit, apples are a good source of vitamins, minerals, and fiber. Also, apples are rich in polyphenols, which are beneficial plant compounds with antioxidant properties. However, the apple is not the only fruit that has such health and nutritional benefits. What makes apples so beneficial to our health is that they are so widely available, mostly affordable, and have a long shelf life. Unlike bananas or papayas, apples are grown in many regions worldwide. Because of their availability, apples are economically and environmentally friendly. Also, apples can be stored longer than other seasonal fruits like strawberries or oranges. Indeed, apples are nearly everyone’s fruit almost throughout the year.

'Eldest daughter syndrome' to the rebellious youngest sibling: Does your birth order shape your personality? 

In most developed countries or established societies, the number of family members is shrinking to as few as three or even two. Declining birthrate, unmarried couples, housing costs, inflation, working mothers, and higher education costs, to name a few reasons why parents are contributing to fewer or no children. Do only children have distinctively different personality traits, like selfishness or narcissism, from children with siblings? Also, it is often said that the firstborns are more responsible and caring because they often look after younger siblings. But are there any significant characteristics, behavioral, or intellectual gaps between earlier-borns and later-borns? In fact, the only child or the first-born child tends to have more time to communicate with and learn from their parents, while later-born children often spend more time with their elder siblings. In the meantime, later-borns often have a better chance of growing up in a better financial situation. Another aspect to be taken into consideration is that young siblings are often compared at the same time, which means they are of different ages. For example, if you compare a teenager, the most sensitive age group, with a six or eight-year-old child, the happiest and carefree age, they certainly exhibit very distinct characteristics. Indeed, there seem to be so many aspects to compare siblings.

The women at the centre of Somalia's construction boom

Located on the Horn of Africa, Somalia is the easternmost country in Africa, facing the Gulf of Aden to the north and the Indian Ocean to the east. Former Italian and British territories united and formed the independent Somali Republic in 1960. However,  the nation had been under domestic conflicts and also suffered a US-backed Ethiopian invasion until 2012, when the Federal Government of Somalia was established. Somalia, with a population of around 18 million, is among the least developed countries in the world, with a large portion of the population living by subsistence farming. In the meantime, in Mogadishu, the capital city, the post-conflict reconstruction has led to a construction and housing boom, and thousands of new buildings have been constructed since 2020. Unfortunately, since this construction boom occurred before building regulations were put into force, there are mounting concerns about the safety of the buildings. Also, the city’s infrastructure, including water and sewage systems, has not caught up with the booming construction. In addition, there is a severe shortage of workforce, particularly construction engineers. Surprisingly for an Islamic society, two young female engineers are now overseeing construction work in a traditionally male-dominated workplace, putting hard hats on their hijabs. Rapid urban development in a least developed country gave young Muslim women the chance to work in a male-dominated construction workplace.

AI to help tell donkeys apart at island sanctuary

Facial recognition is a technology that identifies or verifies a person's identity using their face. It works by comparing a facial image from a camera or a video frame to a database of known faces. Facial recognition is used in various applications, including security systems, smartphone unlocking, law enforcement, airport passenger screening, and automatic ticket gates. It first identifies key facial features from the image, such as the distance between the eyes, the shape of the nose, and the contour of the jawline, and then compares them with the features in the database. Can we use the same or similar technology to identify a particular animal within a herd of cattle? With the help of the University of Southampton, a donkey sanctuary in the Isle of Wight, England, is developing a mobile app to identify particular donkeys by using AI. With the mobile app, visitors will be able to find the identity and profile of the donkey they are interested in soon. In the future, the sanctuary hopes to use the app to help monitor health issues in the animals. Once developed, such technology might help farmers monitor the health and growth of dairy cattle, too.

Why Ukraine is one of the world's most digital countries

Denmark, Estonia, and Singapore are among the few most recognized leaders in digital government. They use digital technologies and data to transform how governments operate and deliver services to citizens and businesses, including tax, pension, IDs, certification, and elections. For example, Denmark is shutting down its postal service by the end of the year because it can provide governmental services without mail. Ukraine is another country that has an advanced digital government platform, apps, and services. Its digital service portal offers 130 services for 22.7 million users, about 60% of the nation’s population. Since citizens’ data are shared by government departments and organizations, users do not have to re-enter their profile or record again when they apply for a benefit. Also, as the country has been at war against Russia since 2022, users can apply for damage compensation for their property or report the location of Russian troops through the app. What creates a digital divide may not be citizens’ digital literacy but a bureaucratic divide.

What are rare earth minerals, and why are they central to Trump’s trade war?

Rare earth elements (REEs) are 17 metallic elements in the periodic table made up of scandium, yttrium, and the lanthanides. Rare earths are ubiquitous in the technologies we rely on today, from smartphones to wind turbines to LED lights and flat-screen TVs. They’re also crucial for batteries in electric vehicles, MRI scanners, and cancer treatments. They are called "rare" not because they are scarce in the Earth's crust, but because they are difficult to find in concentrated, economically viable deposits. Also, while some REEs are relatively abundant, they are usually dispersed and mixed with other elements, making extraction challenging, expensive, and environmentally damaging, which has made China and a few other countries the dominant suppliers of the processed REEs. In fact, while China produces approximately 60% of the world’s raw magnet rare earth elements, it occupies over 90% of the global refined supply. For the USA to domestically process enough REEs for its needs, it’ll take years of financial investment, regulatory approvals, and environmental studies, in addition to access to REEs. No wonder the US administration wants Ukraine and Greenland to become suppliers of REEs.

How airline fees have turned baggage into billions

An airfare is a fee paid by a passenger for air transport. Airfares vary by class, fare restrictions like changeable or cancelable, and seat selection for most airlines. In-flight services such as meals, drinks, and wifi access are mostly optional for budget airlines. Nowadays, what costs you quite substantially is baggage fees. Recently, a growing number of airlines are charging fees for checked baggage, whether for excess, additional, or even the only bag. Furthermore, some European budget airlines, such as Ryanair and Easyjet, are now charging fees on carry-on baggage that doesn’t fit under the seat in front of the passenger. Even if you manage to put all your belongings into a bag and put it under the seat in front of you, you’ll sacrifice the already-squeezed legroom.

‘We do this to survive’: Harvesting opium poppies in Myanmar’s Shan State

Myanmar, also referred to as Burma, is a country in northwest Southeast Asia with a population of around 55 million. The country has been under a civil war since 2021 between the Myanmar military, ethnic armed organizations, pro-democracy forces, and civilian-led militia groups. Bordered by China to the north, Laos to the east, and Thailand to the south, the Shan State of Myanmar is home to several armed ethnic groups, and recently, it has come under Chinese economic influence. The region has become the epicenter of synthetic drug production, opium, and is part of the Golden Triangle, the area around the Ruak and Mekong rivers bordered by Myanmar, Thailand, and Laos. After Afghanistan’s Taliban prohibited opium production in 2022, Myanmar became the world’s largest producer of opium again because the demand surged and so did the price. More farmers in the region are now engaged in opium poppy farming and gum production, which brings them decent money quickly. Those farmers now work like factory workers for illegal produce.

World’s most beautiful castles

A palace is a grand residence of the ruling monarchy or noble family. A fortress is a large, strong building or a group of buildings to defend from attack. A castle is a fortified residential structure for the ruler. Many castles were built during the Middle Ages in places like Europe, the Middle East, and Japan. They were built primarily for defense and residence, but they also served as symbols of power, status, and authority of the ruler. Some of them have moats, high walls, towers, and battlements to reinforce defense. Castles are called Castillos in Spain, Château in France, and Shiro or Jo in Japan. Many were destroyed during battles and wars, while others were demolished or became ruins. However, there are still quite a few castles that are preserved and maintained as historic symbols and landmarks, such as Himeji Castle in Japan, Edinburgh Castle in Scotland, and Prague Castle in the Czech Republic. Visiting a castle, you can not only enjoy seeing the beautiful architecture but also feel the historical significance of the structure.

The everyday activity that can reveal your brain's age

The faster you walk, the slower the aging of your physical and cognitive health seems to be, according to studies. Walking speed varies by age, person, and health conditions. For example, the average walking speed for 60-69 year-old men is around 1.43 meters per second, but it declines to below one meter for 80-89 year-olds. Also, a 45-year-old adult may walk as fast as healthy 20-year-olds, while others walk as slowly as much older adults. Walking relies on the coordination of various body systems, including bones, muscles, eyes, heart, lungs, brain, and nerves. As you age, these functions slow down, which affects the person’s walking speed. Also, if your physical or cognitive conditions decline faster than your aging, your walking speed becomes slower than that of others in the same age group. Then, how fast is normal or too slow at your age?

World fertility rates in 'unprecedented decline', UN says

Just several decades ago, countries in eastern Asia such as Japan, South Korea, and China were struggling to deal with an increasing number of newborns. For example, China implemented the infamous one-child policy in 1979 to control population growth, but in the last several years, it has been trying to increase the low fertility rate of only 1.2 children per woman, which is well below the replacement level of 2.1. Also, the number of Japan’s newborns exceeded two million between 1971 and 1974, but it fell to below 700,000 last year, much fewer than the number of deaths of 1.6 million. According to the recent UN report from a survey of young adults and those past their reproductive years in 14 countries with various fertility rates, one in five said they haven't had or expect to have as many children as they desire, even though most of the respondents want to have two or more children. Nearly 40% cited financial limitations as the main reason for not having the desired number of children.

Google’s DeepMind CEO says there are bigger risks to worry about than AI taking our jobs

AI is getting many kinds of jobs and tasks done more easily, productively, and even more creatively. It finds information much faster from vast resources, organizes it, and provides solutions. Also, AI generates code or creates stories or artworks based on natural language prompts. Many kinds of jobs have already been affected or replaced by this autonomous and even creative intelligence, and more are expected. Indeed, humans have experienced such job transformations when innovation appeared, such as steam engines, automation, computers, and the Internet. But as AI is getting better at almost all intellectual tasks than humans, it could be used for harmful or malicious purposes, such as cyberattacks, disinformation campaigns, and creating content like deepfake pornography. Artificial General Intelligence (AGI), which is capable of performing most intellectual and cognitive tasks that humans can, is on the horizon. Humans may no longer be capable of detecting and stopping AI crimes, but AI police may be.

'Traffic saved me': Student missed Air India crash by just 10 minutes

On June 11, Air India flight AI171 bound for London Gatwick crashed only moments after takeoff in Ahmedabad, western India, at 13:39 local time. All of the 12 crew members and 241 passengers onboard the flight were killed but one. The sole survivor on board was a 40-year-old British man of Indian origin who was seated in economy class seat 11A. Surprisingly, there was another lucky person who did not die in the crash. An Indian student who lives in Bristol had been visiting western India for a holiday. She was scheduled to fly the same flight and was assigned to seat 36G. However, she arrived at the airport 10 minutes late to board the plane due to heavy traffic and missed the flight. After she left the airport sadly, she learned that the airplane had gone down.

The pandemic generation: How Covid-19 has left a long-term mark on children

Five years have passed since the COVID-19 outbreak spread around the world. Many places, including offices, shops, restaurants, and schools, were shut down for months or even longer. As frontline school teachers have been witnessing, such social isolation appears to have profound effects on children, including toddlers. When they were at the age of learning the foundation of social communication, they were only with a few family members in an isolated space without interactions with other people or the outside world. Also, as many school children had to take classes online or from their caregivers for months or even longer, they missed the opportunities to interact with other students, participate in school or club activities, and have hands-on learning. Teachers have been adjusting curricula to help those students catch up with the requirements. Researchers are studying the social, mental, physical, and economic impacts of the missed opportunities on the pandemic generation.

Humanoids are general-purpose, bipedal robots modeled after the human form factor and designed to work alongside humans to augment productivity. They are expected to learn and perform tasks in factories, warehouses, kitchens, hospitals, and more, where hands and legs are needed. On the practical side, they can learn to move and pack boxes, assemble parts and modules, flip patties for burgers, or lift and carry a person. Chinese humanoid inventors and developers are also trying to have robots learn to run a road race (Vol. 4749), dance, and exercise. Recently, a humanoid robot fighting competition was held in Hangzhou, China. The participating robots had to go through stress tests to prove their ability to perform in the fight.

Japan’s annual births fall to record low as population emergency deepens

The population of the Japanese declined by nearly 900,000 last year to 120 million. While over 1.6 million died, fewer than 700,000 were born. Why were there so few newborn children? In fact, 1974 was the last year when Japan’s total fertility rate marked 2.0 or higher. The number has been consistently falling to 1.50 in 1992, 1.36 in the millennium year, and 1.15 last year. Also, fewer than 500,000 Japanese couples got married in the last few years. Japan is one of the East Asian countries, like China and South Korea, whose number of newborns and population have been declining rapidly. Also, these societies are aging fast. Nearly 30% of Japan’s population is 65 or older, who are eligible for a pension. Despite the financial incentives and social support, young people in Japan and these countries don’t seem to be encouraged to get married or have children. In the meantime, the number of foreigners living in Japan increased by 337,000 to 3.6 million. They are young, eager to work, and reproductive.

How your pets alter your immune system

Living with animals can significantly enhance our lives by providing companionship, reducing stress, and offering a sense of purpose and meaning. Trained service animals, in particular, provide support to the disabled both physically and mentally. Domesticated animals also contribute to our physical health by increasing exercise and potentially impacting heart health. Indeed, animals make us work physically. In addition, studies have found that children living in farming communities where cattle, farm animals, and pets live close to humans have a lower risk of allergies, asthma, and hay fever. That is because exposure to microbes during infancy and childhood helps train the immune system to distinguish between harmless and harmful microorganisms, fostering tolerance to commensal bacteria and preventing overreactions to foreign invaders. While AI-powered humanoid robots might take over or help human labor, pet animals do provide physical and mental benefits to our lives.

One death every seven minutes: The world's worst country to give birth

With an estimated population of nearly 240 million, Nigeria is the most populous country in Africa and the sixth most populous country in the world. Its population is growing rapidly due to a high fertility rate, nearly five births per woman, a large young population, and relatively low death rates. However, the number of Nigeria’s maternal deaths, the death of a woman while pregnant or within six weeks of the termination of pregnancy, is the highest in the world, with about 75,000 deaths in a year. Severe bleeding, high blood pressure, infections, and prolonged or difficult labor are common causes of maternal deaths, along with unsafe abortions. There were only 121,000 midwives for a population of 218 million in 2021, which is well short of the 820,000 that the WHO recommended for the country. Also, many healthcare facilities lack proper equipment, supplies, and trained experts. In addition, many expecting mothers, especially in rural areas, are reluctant, cannot afford, or don’t have access to hospitals. Since more and more young girls are growing into reproductive age, Nigeria needs to improve maternal care urgently.

Hagia Sophia: Secrets of the 1,600-year-old megastructure that has survived the collapse of empires

The Byzantine Empire, also known as the Eastern Roman Empire, was a continuation of the Roman Empire in the East, lasting from 330 CE to 1453 CE. Its capital was Constantinople, modern-day Istanbul, which was founded by Emperor Constantine. The Byzantines developed their own distinct cultural and religious practices, including Eastern Orthodox Christianity. Greek became the official language, and the Byzantine Empire preserved and developed aspects of Greco-Roman culture. Hagia Sophia, meaning holy wisdom in Greek, is a significant historical and architectural site built in 537 CE in Constantinople. It had been the hub of Orthodox Christianity and the last standing symbol of the Byzantine Empire until it was conquered by the Ottoman Empire in 1453. Subsequently, the holly church was converted into a Sunni Muslim mosque, and minarets were added. In 1935, Hagia Sophia was converted into a museum by Atatürk, the founder and the first President of modern Turkey, but in 2020, it was re-converted into a mosque. Only the second floor is now serving as a museum where tourists can enjoy seeing and feeling the magnificent architecture and artworks that represent the long history of the Byzantine Empire to the Ottoman Empire, and the religious conversion from Christianity to Islam.

The Hajj explained visually

Today ends the annual Hajj, an annual Islamic pilgrimage to Mecca, Saudi Arabia. It is a mandatory religious duty for financially and physically capable Muslims at least once in their lifetime. Though depending on where the pilgrim travels from, it costs at least hundreds to thousands of dollars to take part in the five to six-day pilgrimage to Mecca. In addition, pilgrims have to bear the lost income and the cost of living of their family member at home during the trip. Furthermore, Hajj is physically demanding, challenging, and even dangerous. Pilgrims are required to walk more than 10 kilometers each day under the scorching desert sun at temperatures over 40 degrees Celsius. In fact, temperatures during last year’s hajj soared past 50 degrees, and over 1,300 people on the Hajj pilgrimage in Mecca died due to extreme heat.

Five-year forecast paints a troubling picture of extreme weather and deadly heat

10 years ago at the UN climate summit in Paris, 190 countries agreed to limit global warming to 2.0 degrees Celsysus, preferably 1.5 degrees, warmer than the time before the Industrial Revolution when humans started burning a substantial amount of planet-heating fossil fuels, so-called the Paris Agreement. However, the planet has experienced the 10 warmest years, and last year, it crossed the 1.5-degree threshold. Now, meteorologists predict there is a 70% chance that global warming will exceed 1.5 degrees Celsius, and even a higher chance that we’ll experience the hottest year on record in the next five years. As the planet warms, sea ice and glaciers in polar regions melt, causing further sea level rise. Also, glaciers in high mountains collapse and destroy settlements in valleys, like Blatten in Switzerland (Vol. 4788). China, the largest emitter of warming gases, has been promoting new energy vehicles (NEVs) and extending its high-speed railway network to reduce fossil fuel emissions. However, the US, the second-largest warming gas emitter, decided to withdraw from the Paris Agreement again. The world seems likely to experience warmer temperatures, more extreme weather conditions, and further sea level rise in the coming years.

Millions of honeybees abuzz after truck overturns in Washington state

Honey bees play a vital role in plant reproduction and food production. While foraging for nectar, Bees collect pollen on their bodies. When they visit another flower, some of this pollen is deposited on the stigma, enabling fertilization. This process is crucial for the reproduction of many crops, including nuts, vegetables, berries, citrus, and melons. Beekeepers manage and care for honeybee colonies for harvesting honey and other hive products like beeswax and pollen. They also provide pollination services for crops. They transport bees to take advantage of different growing seasons and control the environment in which their bees live. On May 30, in northwestern Washington state in the USA near the Canadian border, a truck carrying over 30 tons of active honey bee hives rolled over, and as many as 250 million honeybees escaped. Local beekeepers responded to rescue as many honeybees as they could to rehive the worker bees and find their queen bees. The public was warned to avoid the swarm until they were retrieved.

Glacier collapse buries most of Swiss village

Global warming is melting ice sheets in Antarctica and Greenland, raising sea levels around the world. Rising sea levels are posing a significant threat to coastal areas, especially in tropical and subtropical river deltas, low-lying islands, and densely populated coastal zones. Warming temperatures are also melting snow, ice, and glaciers in arctic regions and mountains at an unprecedented pace. Blatten is a small mountain valley village in Switzerland with a population of around 300. On May 28, approximately 90% of Blatten was lost under a landslide triggered by the collapse of the Birch glacier. Debris destroyed large parts of the village, and ice, earth, and rock partially blocked the Lonza River. Thanks to prior warning, all the residents but one had evacuated from the village safely before the glacier collapsed. Glaciologists have been monitoring melting glaciers and permafrost and warning some other alpine towns and villages of such incidents. Since the glacier is unstable, many of the residents of Blatten may never be able to return to their homes.

So what happens to America’s 114 billion pennies once the US stops making them?

A penny is the smallest denomination coin in the US, worth 0.01 or a cent of a dollar. The penny was one of the first coins made by the US Mint, a bureau of the Department of the Treasury responsible for producing coinage, that entered circulation in 1793. A modern US penny is made of  97.5% zinc and 2.5% copper, and the cost of producing a penny is now 3.69 cents per coin. Thus, the US Treasury Department has decided to stop producing pennies next year. While existing pennies will retain their value for transactions indefinitely, those in circulation will decrease gradually. So, what’ll happen if you try to pay your bill in cash? In Canada, the distribution of pennies ceased in 2013. Retailers were then no longer expected to return pennies as change for cash purchases, and they started to round purchases to the nearest five cents, even though goods are still priced in one-cent increments. For example, totals ending in 1 or 2 round down to 0, totals ending in 3, 4, 6, or 7 round to 5, and totals ending in 8 or 9 round up to 10. Non-cash transactions like credit cards or mobile payments will not be affected and will be paid to the exact cent. After all, it is a matter of cash transactions, not a re-denomination of the currency.

Scientists propose novel way of treating mosquitoes for malaria

Malaria is a life-threatening disease spread to humans by some types of mosquitoes, which are still common in tropical and subtropical countries. People who have malaria usually feel very sick with a high fever and shaking chills, and in severe cases, it can cause jaundice, seizures, coma, or death. In fact, as many as 600,000 people die of malaria each year, mostly in Africa. The infection does not spread from person to person, but is caused by a parasite, which is carried by some type of mosquito. Human malaria infection is initiated when a female anopheline mosquito injects Plasmodium sporozoites into the skin during a blood meal. To prevent malaria, you should reduce contact with mosquitoes by wearing protective clothing, using window screens, and sleeping under a bednet. You can also use insecticide to kill mosquitoes, but they’ve become resistant to it. Now, researchers at Harvard University have come up with a new way to prevent malaria by using drugs that kill parasites in mosquitoes instead of mosquitoes themselves. In their test, the drug applied onto bednets didn’t kill all mosquitoes, but killed all the parasites. After all, it is the parasites that spread malaria, not mosquitoes themselves. More research is still needed, but the effectiveness of bednets against malaria infection might improve significantly.

'Shrinking Nemo': Smaller clownfish sound alarm on ocean heat

Finding Nemo is a 2003 animated comedy-adventure movie by Disney about a tropical clownfish that lives in the Great Barrier Reef. He embarks on a dangerous journey to find his son after his son, Nemo, was captured by a diver and taken to Sydney. 20 years after the movie production, ocean temperatures heated up and caused a severe and widespread coral bleaching event. Recetnly, new research found that clownfish living on coral reefs became shorter by several millimeters during the heatwave while keeping the same weight. The researcher thinks the clownfish made themselves smaller to survive with less food and oxygen. The surprising finding could help explain the declining size of other fish in the world’s oceans.

Denmark raises retirement age to 70 — the highest in Europe

Retirement age is the age at which people usually retire from work and become eligible for social security or a pension. With better health and longer life expectancy, more people are able to and want to keep working in their 60s or even 70s. This is good and needed for aging societies whose pension budget has been squeezed due to rising pension costs, underfunded funds, and poorer investment returns on pension fund assets. Recently, the retirement age has been increased in many developed countries whose society is aging rapidly: 67 in Australia, 65 in Canada and Japan, 63 in China (men), 62 in the USA, and 60 in Turkey (men). In Europe, the pension eligibility age is 62 in France and Italy, 63 in Germany, 66 in the UK, and 67 in Sweden and Denmark. This month, Denmark’s parliament has voted to raise the retirement age to 70, the oldest in the world, in order to maintain its welfare for future generations. In fact, more people continue working while receiving a pension nowadays, thanks to their health and more accommodating work conditions. In the meantime, it may be a stretch for those who work for physically demanding jobs like construction or teaching. How old is too old to work seems to depend on the individual’s health condition, mental motivation, and the type of job.

India’s caste system is controversial and discriminatory. So why is it being included in the next census?

Originating as far back as 1500 BCE, India's caste system is one of the oldest forms of social stratification in the world. The Varna system consists of four divisions: Brahmins (priests and scholars),  Kshatriyas (warriors and rulers), Vaishyas (merchants and landowners), and Shudras (laborers and service providers). The Dalits, formally known as “Untouchables”, were considered below the Varna system. Over time, the Varna became rigid and birth-based, and this social division persisted in India’s society until it was banned in 1950 under the new constitution. However, this segregatory stratification persists in today’s India, the world’s most populous country. For example, only about 5% of marriages are inter-caste, and there are gaps in wealth, health, and educational attainment between different castes. The national and local governments have been offering affirmative action quotas and benefits for jobs and educational opportunities for people in marginalized castes, but without knowing exactly who and how many in a specific caste. In order to better aid and allocate resources to those who need the most, Modi’s administration recently announced that caste will be included in the next national census, which was last surveyed in 1930 during the colonial period. India is the world's most diverse country, with a variety of languages, religions, ethnicities, customs, and social structures, and different regions boast unique blends of traditions and cultures.

A crucial system of ocean currents is slowing. It’s already supercharging sea level rise in the US.

It’s not just melting ice sheets from Antarctica and Greenland that cause sea level extremes, but storm surges, tides, waves, and the expansion of seawater itself all affect sea levels. Ocean currents also affect sea levels. When a current weakens, water becomes less dense and expands. For example, flooding on the US Northeast coast has risen substantially as the Atlantic Meridional Overturning Circulation (AMOC) weakens. In addition, weakened AMOC seems to have affected the flow of the Gulf Stream and caused water to flow back onto the Northeast coast. According to a new study, up to half of the flooding events along the northeastern coast in the last two decades were driven by a weaker AMOC, which could have been interconnected with warming sea temperatures. We now know better why some coastal regions are experiencing higher sea level rise than others.

31 million tons of supercharged seaweed is creeping toward beaches in Florida and around the Caribbean

Sargassum is a brown seaweed that typically floats on the surface of warm, nutrient-rich waters. While it provides vital habitat and food for various marine species, including fish, crabs, shrimp, sea turtles, and birds, it could create "brown tides" that smother coastal flora and fauna, including coral reefs, when it blooms. Also, when it rots on shore, it emits harmful gases and stinks. This year’s bloom of sargassum in the Caribbean region, the Gulf, and the South Florida region is estimated to be 31 million tons, about 40% more than the previous record in 2022. Rising ocean temperatures due to global warming is the first to blame. Also, runoff of the nitrogen-rich agricultural fertilizers from the Mississippi and Amazon rivers supercharges the brown seaweed. Sargassum’s impacts on the ocean ecosystem, fisheries, tourism industry, and health of coastal residents are substantial. But just like other environmental disasters and catastrophes that are triggered by human-caused global warming, sargassum may bloom even more in the coming years.

About three decades ago, in the 1990s, when their parents were likely born, Jessica, Ashley, and Emily were the top three names for girls, and Michael, Christopher, and Matthew were the top three names for boys. When their parents were likely born in the 1960s, Lia, Mary, and Susan were the most popular girls’ names, and Michael, David, and John were the top three names for boys. Last year, Olivia, Emma, and Amelia were the top three girls’ names, and Liam, Noah, and Oliver were the top three boys’ names. You can see that none of these names are seen in other generations. Interestingly, the popularity of these names has been consistent. Olivia for girls and Liam for boys have been at the top of the list for the last five years, and other top names have been on the top list, too. As a matter of fact, the most popular girls’ name by sound is Sophia/Sofia, which were ranked number 6^th and 10^th, respectively. Combined, Sophia/Sofia outnumbers Olivia by a substantial margin.

Dear MEL Topic Readers,

Trump wants to end birthright citizenship. Where do other countries stand?

In many countries in Asia and Europe, have the right of blood principle, where children legally inherit their nationality from their parents, regardless of their birthplace. In contrast, around 30 or so countries, including the USA, grant citizenship to anyone born in the country, called birthright citizenship. However, as illegal immigrants and birth tourism, where foreign women visit a country to give birth, increase, some countries that once granted birthright citizenship have revised the policy, such as India, Ireland, and the Dominican Republic. Now, the Trump administration is trying to terminate the US birthright citizenship policy that was established by the Constitution about 160 years ago to address the legal status of freed slaves. It is part of the move to deny citizenship to the children of people who are either in the US illegally or on temporary visas, including birth tourism. Will the US just end the 160-year-old birthright citizenship policy or even revoke already-granted citizenship of the children of illegal or non-permanent residents?

Dear MEL Topic Readers,

Super-sized cruise ships are becoming the norm. Is there an end in sight?

One way to enjoy your vacation is to get on a cruise ship. Over 37 million passengers are expected to cruise this year alone, about the same number of foreign visitors to Japan last year, and the number is expected to grow in the coming years. Also, more and more mega cruise ships have been and will be added to the cruise market, which accommodate thousands of passengers at a time. Some of them have more than 3,000 cabins and a capacity of 8,000 guests. Those mega cruisers are larger than mega resort hotels on land, and are almost like resort destinations by themselves. To accommodate passengers of different generations, companions, preferences, and expectations, those ships have neighborhoods or districts in addition to various dining options, shows, shops, swimming pools, playgrounds, and other entertainment facilities. Typically, cruise ships visit popular tourist destinations or tropical islands, but nowadays, some cruise vacations offer an integrated experience in a private island or destination with water parks or beaches. But what about the environmental impact (Vol.4774) of increasing floating cities on the oceans?

Dear MEL Topic Readers,

8 ways to travel more sustainably in 2025

When you travel to a popular tourist destination in high season, you’ll pay high prices for everything and wait in lines to visit or take photos at hotspots. Also, as overtourism is negatively impacting local communities, residents, and the environment, travelers to popular destinations like Barcelona, Venice, and Kyoto aren’t so welcome any longer. In addition, when you fly, drive, and stay, you’ll leave substantial carbon footprints. Isn’t it time to rethink how to plan your travels? Instead of heading for travel hotspots at peak times, you could choose less crowded or popular places in the off-season and experience local cultures. You may take a train rather than flying so that you can enjoy the scenery along the way instead of gazing at your smartphone in a tiny seat on the flight. Also, there is an increasing number of environmentally friendly, sustainable accommodations. How about dedicating some time of your stay to an environmental, cultural, or social activity, such as beach cleanups or habitat restoration? There are many ways to enjoy your travel with less impact on society and the environment.

Dear MEL Topic Readers,

Can AI care for your loved ones?

A baby monitor has an audio or visual monitor that allows the carer to remotely listen to or observe the baby from a different place. Such monitors are also used to monitor pets, patients, or elderly people. They may be programmed to send an alert if an unusual pattern is monitored, such as excessive noise or sudden movement. When AI technologies are embedded in such monitors, they will learn the normal noise or movement patterns of the individual, so that they can alarm the carer when attention is required. This could eliminate, or at least reduce, routine checks or constant monitoring of the carer in hospitals or nursing homes. As many developed societies like the UK and Japan are aging fast, more people will need care 24/7 while having fewer carers. Machines with learning capabilities may help care for those in need of help better.

Dear MEL Topic Readers,

He was killed in a road rage incident. His family used AI to bring him to the courtroom to address his killer

Visual images are impactful, and sometimes more appealing and convincing than written statements or evidence to the audience. The family members of a victim of a road rage incident in Arizona, USA, used AI to recreate the victim to speak in the courtroom. It was played not as evidence but to give the deceased family member the chance to express forgiveness to the defendant during the sentencing hearing. They trained AI software platforms with photos and videos of the victim to create a video replica to speak what he would have said to the shooter. The defendant's lawyer indicated that the use of the video in a courtroom might become an issue when the case is appealed, even though it was not used as evidence. Nowadays, you can use AI software to create a video of a dead person, which could be played to remember the person or deliver messages. Indeed, avatars and AI-created yourself can speak for you even after your death.
