Dear MEL Topic Readers, 
This is why you only breathe out of one nostril at a time
Your nostrils are the entrance to your respiratory system. They warm, condition, and filter the air you breathe. They also house your olfactory organs, which give you the sense of smell. That’s why when your nose gets stuffy or blocked, you don’t smell or taste well. Without noticing, your nostrils naturally switch between a dominant nostril for airflow while the other rests, called the nasal cycle. Regulated by the autonomic nervous system, this work-and-rest cycle prevents drying, cracking, and maintains mucus health. The cycle usually shifts every two to five hours without our recognizing it. Which of your nostrils is at work now?
Read the article and learn about the mechanism of our nostrils and the nasal cycle.

How Iranians are evading internet blocks to contact family abroad
Iranians, especially those who live in Tehran, have been under heavy bombardment by Israel and the USA since February 28. Also, they have been under an internet blackout by their own authorities since January 8. Without phone or internet connections, how have they been conveying their situations to those who live abroad? One analogue yet practical way to talk to others abroad is to use a Turkish phone and an Iranian phone near their border, where signals from both countries reach, and hold them together while talking. Another, more digital way is to use a Virtual Private Network (VPN), which secures your internet connection by creating an encrypted tunnel for your interactions. Connecting to the Internet via VPN, your data, location, and online identity are all hidden from the Internet Service Provider (ISP) or sensorship. Because of the desperate demands to hear the voices or messages from their loved ones, the prices of such arrangements have skyrocketed recently. However, there is no other way for Iranians to establish communication with the outside world. And when they talk, they say they are doing OK, no matter how heavy the bombardment around them might be. Who created a situation like this?

Dear MEL Topic Readers, 
How much of the Gulf’s water comes from desalination plants?
The total population of the six Gulf states, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates (UAE), is a little over 60 million, showing an increase of about 20% in the last decade. However, the area has no permanent rivers and receives very little rainfall. How does the arid region supply sufficient water to its growing population, businesses, and farming? Since the GULF countries border the Persian Gulf, they are making water by desalinating seawater. They produce more than 300 liters of water per resident each day from seawater at over 400 desalination plants along their coasts. Desalination of seawater is the process of removing salts, minerals, and impurities from seawater to produce water drinkable or suitable for irrigation and industrial use by membrane filtration or thermal distillation. Once processed, the water is then distributed through pipelines or in containers. In the Gulf region, plants and pipelines seem essential to produce and distribute essential liquids.

AI is exhausting workers so much, researchers have dubbed the condition ‘AI brain fry’
What if a dozen browser tabs open all at once, waiting for your judgment or directions? As more efficient and sophisticated AI tools are introduced in workplaces, more workers and managers are experiencing cognitive overload, called AI brain fry. It is mental exhaustion from using or supervising AI tools beyond one’s cognitive capacity. While asking an AI chatbot questions or having an AI tool do simple tasks like creating charts greatly saves time and workload for most workers, supervising what AI tools produce requires managers and specialists to conduct fact-checking and judgment, and fast. This is not a simple task like driving a car on a highway, but more like riding a monster motorcycle on a race track, where a simple mistake could easily lead to a fatal crash. To avoid such cognitive overload by new tools, users of powerful AI tools need to learn how to make better use of them within their cognitive capacity. Longer work hours certainly won’t help you work with AI, but attention span will.

Former leader Ardern has left New Zealand. She’s not the only one
Compared with New Zealand, Australia is 28 times larger in land size and five times larger in population. Australia’s average economic output per person, GDP per capita, is over USD 65,000, and New Zealand's is around USD 48,000. Last year, both countries had about a 3%+ inflation. Sydney and Melbourne are the two largest cities in Australia, with a population of over five million respectively, while roughly one-third of New Zealanders, or 1.7 million, live in the largest city, Auckland. Thanks to the free movement agreements, citizens of either country can move and live in the other freely. Which of these two closely located Oceanian countries offers economic advantages over the other? Recently, migration between Australia and New Zealand has experienced a significant surge, with record numbers of New Zealanders moving to Australia for higher wages, better opportunities, and lower costs of living. Last year, over 120,000 New Zealanders emigrated, fueled by rising living costs and a weakening job market, and 60% of them settled in Australia, including the former prime minister and her family. Economic advantages seem to overwhelm national identity or values to many young people and families, causing so-called brain-drain to New Zealand.

Where do the 35 million foreigners living in the GCC come from?
Around 60 million people live in the six Gulf monarchies: Saudi Arabia, the United Arab Emirates (UAE, including Abu Dhabi and Dubai), Kuwait, Oman, Qatar, and Bahrain. These Gulf Cooperation Council (GCC) countries share the same religious, cultural, and social values, including Islamic identity, Arabic language, and Bedouin-merchant lifestyle, as well as modest behavior and hospitality. These countries are all scarce in water resources, but extremely rich in oil and natural gas resources, which generate the vast majority of their government revenues and contribute a significant portion of their GDPs. Also common among the GCC countries is their heavy dependence on foreign workers, or expatriates. Even though nationals are the majority of the population in Saudi Arabia and Oman, non-nationals outnumber the nationals in the other four countries, most significantly in Qatar and the UAE, where over 80% of their populations are non-nationals. Then where do those expatriates come from?

These filmmakers know exactly how to get you hooked on bizarre one-minute dramas
A study found that the time an average person spends on a screen is now only 47 seconds, significantly shorter than in the pre-smartphone era. (Vol.5072) However, when it comes to a “micro-drama”, there is only a second or two to get viewers’ attention and stop them scrolling further on their smartphones.  Originating in China, a micro-drama is a highly serialized, short-form video series designed for mobile viewing, featuring dozens of 1–2 minute episodes with fast-paced, melodramatic plots, often shot in a vertical format. Viewers can watch the first five to ten episodes free, and then need to pay to watch the remaining episodes. Therefore, it’s not the title or trailer that grabs viewers’ attention but the impact of the beginning scene. In production studios in Korea, screenwriters, producers, and editors all use AI to save time and cost to produce numerous episodes and titles of micro-dramas. It seems that the time to grab and keep attention is getting shorter as people scroll the screen faster.

You’ll likely move on in 47 seconds. Can I hold your attention a little longer?
It seems that most of us live in a life where we switch our attentions from one thing to another much faster than ever before. On the smartphone, many people keep swiping through the next videos or images in less than a minute. Also, people quickly turn their eyes to the screen whenever they have a few seconds to spare. A study found that the time an average person spends on a screen is now only 47 seconds, significantly shorter than in the pre-smartphone era. When there is always more content that grabs your interest at the blink of your eye, you may find it difficult to pay attention to off-screen activities and interactions that don’t gratify you with such instant pleasure. Then, how should you switch focus and concentrate on the work or task that requires good attention?

Five countries that are actively welcoming travellers in 2026
Tourism contributes economy, creates jobs, and improves infrastructure, if planned and managed sustainably. But if the number of tourists exceeds the sustainable capacity, it is labeled as overtourism, which often ends up creating bans, caps, and raising fees for tourists to curb the number, like in France and Italy. Still, there are countries that are welcoming more international visitors, in Africa, South America, and Europe.
Namibia, a South African country that borders the Atlantic Ocean and also South America, offers conservation-minded wildlife-spotting tourism. Brazil, the South American giant with the Amazon River, is encouraging visitors to travel around different regions, seasons, and types of experiences. Vietnam, an elongated coastal nation stretching over 1,600 km from north to south with a diverse climate and varied landscapes, has eased visa requirements and is about to complete upgrading Ho Chi Minh City’s international airport. Lithuania, a small Baltic country, is projecting to increase not just the number of travellers but the length of their stay so that they can experience local culture and food better. Canada, the world’s second-largest country after Russia, offers diverse tourism attractions stretching over 7,000 km east to west across six time zones. So, it’s better not to limit your travel destinations to already-popular world heritage sites, but rather expand your scope to other attractive places where local nature, culture, gastronomy, and environment are waiting for your visit.

We feel it in our bones': Can a machine ever love you?
Loving someone is not just having a romantic feeling but involves a deep, conscious commitment characterized by care, respect, and unconditional support for another person's well-being, growth, and happiness. As the relationship develops, it often evolves beyond initial infatuation into a stable partnership built on trust, shared values, and mutual sacrifice, according to an AI overview. Nowadays, some people are emotionally so engaged with AI that they feel love for their AI companion or avatar. In an extreme case, a Japanese woman had a marriage ceremony with a ChatGPT character (Vol.4995). However, unlike human companions, chatbots are designed to engage users and agree with their perspectives and emotions. While they become comparable to humans in understanding emotions, chatbots are often submissively responding without feeling anything. But as people use AI more from an earlier age, another kind of “love” might be developed. In fact, many people love their pets just like their family members, even if they don’t speak the same language.

The business of not ageing: Why people are spending $1,300 on longevity treatments
There are quite a few evidence-backed lifestyle habits to live longer, healthier lives, such as eating a nutrient-rich, balanced diet, engaging in regular physical activity, getting enough sleep, refraining from smoking or drinking alcohol, managing stress, and maintaining social connections, none of which costs any money but one’s mindset, attitude, and determination. In the meantime, there is an increasing number of businesses that offer longevity treatments, such as mindfulness sessions, mental longevity, diagnostics, neurostimulation, sleep optimization, and stress-resilience therapies, none of which seem to be supported by clinical trial data or evidence. These diagnoses and customized treatments cost thousands of dollars, but there are quite a few people who don’t mind spending money to delay aging and live longer. Indeed, longevity treatment might be a healthier way to spend money than on luxurious ornaments or dresses. However, if you live alone longer than your loved ones or friends, you’ll miss them a lot. Will there be loneliness treatments that you can buy?

'The damage is already there': A controversial airport comes to Peru's Sacred Valley
Sitting above the Urubamba River valley in the Andes Mountains in Peru, Machu Picchu is a famous Incan citadel. Built around 1450, this historic sanctuary stands 2,430 meters above sea level in the middle of a tropical mountain forest, which was abandoned about a century later during the Spanish conquest. Designated a World Heritage Site in 1983, it is one of the most iconic symbols of the Inca civilization and a major archaeological site in the Americas, drawing around 5,000 visitors a day, 1.5 million annually. But Mach Picchu is hard to reach. After arriving at Lima, Peru’s capital, which is a long way from the other continent, you need to take a 1.5-hour domestic flight to Cusco, then take a four-hour train to reach Aguas Calientes to catch a 30-minute shuttle bus to the entrance. However, a new international airport has been under construction for decades in Chichero, only about a 1.5 to 2-hour train ride to Aguas Calientes. Once completed, the now-hard-to-reach Incan monument will be much more accessible to many more travellers. Already, more hotels are being built to accommodate more guests in the area. But what will happen to Incan roads, irrigation systems, structures, farmlands, and an inland salt mine, some of which are all still in use? Also, can the infrastructure and environment sustain so many visitors, workers, and businesses that are planned on paper? Conservationists, environmentalists, archeologists, indigenous communities, and even local operators and guides are protesting the airport project.

How where you grow up affects your personality
Which determines human behavior, personality, and traits, nature or nurture? Nature, or genetics, refers to innate biological factors inherited from parents, including DNA, eye/hair color, and genetic likelihood of developing certain diseases or mental health conditions. Nurture, or environment, includes external factors, such as upbringing, parenting styles, social relationships, culture, and life experiences. How different would the personal traits of identical twins, who share almost identical DNA, be if they grew up in different families, places, or cultures? For example, while people in the West tend to be more individualistic, the Japanese people are often more collectivistic. Also, religions play a significant or fundamental role in shaping personal identity and cultural values. In the meantime, research shows that Intelligence Quotient (IQ) is over 50% heritable on average, while about 40% of personality traits are heritable, meaning the rest is developed or formed by the environment and opportunities. All in all, it doesn’t seem to be just one or the other, but both nature and nurture develop one’s personality and capability.

The island with an air-conditioned ‘forest’ to cope with scorching summers
Bordering Saudi Arabia and surrounded by the Persian Gulf, Qatar is a small peninsular Arab country with a population of just over 3 million, most of whom are expatriates and migrant workers. It is rich in natural gas reserves, contributing to over 18% of global liquid natural gas (LNG) exports. The airport in the capital, Doha, is a major global hub, serving more than 50 million passengers a year. Doha has become one of the most popular tourist spots in the Arabian Peninsula. However, Qatar has an arid, hot desert climate, with summer temperatures exceeding 40 degrees Celsius, making outdoor activities intolerable. To offer a year-round pleasant atmosphere, Doha’s Al Gharrafa and Umm Al Seneem parks blow cold blasts piped up from the street. People can jog, walk, or shop outside comfortably even in summer. On Gewan Island, a newly added man-made archipelago, visitors can enjoy walking a promenade under its air-conditioned forest. Artificial Intelligence is everywhere, helping people with their jobs. Doha’s artificial environment is certainly one of a kind, providing leisure to the residents and attracting visitors from around the world.

China’s latest AI is so good it’s spooked Hollywood. Will its tech sector pump the brakes?
During the Cold War, the USA and the Soviet Union competed in their spaceflight technologies by sending animals and men into space, and landing astronauts on the Moon. It sparked rapid advancements in aerospace technology, reforms in science education, and the nuclear arms race. In this decade, military drones, humanoid robots, and AI have made significant technological advancements to the point where conventional technologies, skills, and labor are being replaced. Drones and counterdrones are now the major forces in the Russia-Ukraine War. Humanoid robots are working in factories, stores, and restaurants along with human coworkers. AI is taking the place of skilled, experienced, and knowledge workers. And China seems to be leading the race in speed, scale, and economy, thanks to the AI Plus initiative to integrate artificial intelligence across all economic, industrial, and social sectors, transforming AI from a technical tool into a core driver of productivity. Only about two years after ChatGPT’s debut, DeepSeek, a high-performance, cost-effective AI model, was released by a Chinese AI startup. To kick off the Lunar New Year, a band of humanoid robots performed Kung Fu, spin kicks, and back flips at the country's annual Spring Festival Gala. Then, in early last month, movie stars, celebrities, and famous characters appeared in cinematic videos and went viral. They were created with a new AI tool called Seedance 2.0 by ByteDance, a Chinese tech giant known for TikTok and Douyin. It is such an advanced and sophisticated tool that short videos are created from images, audio, video, and text prompts quickly and effortlessly. For example, you can see a fighting scene of famous stars like Tom Cruise and Brad Pitt. Hollywood was quick to react by issuing a warning notice to ByteDance for copyright infringement. As AI improves, so do deepfakes. The race and battle are already going on to protect copyrights from infringement and the public from being misinformed.

Six possible effects of Trump's climate policy change
Last month, the US president erased the scientific finding that climate change endangers human health and the environment and deregulated federal greenhouse gas emission standards for all vehicles and engines of model years 2012 to 2027 and beyond. The administration claims that the deregulation restores consumer choice, makes more affordable vehicles available for American families, and decreases the cost of living because of the lower cost of trucks. This reversal action against the global efforts will not only remove limits on carbon dioxide, methane, and four other greenhouse gases that spur heat waves, droughts, wildfires, and other extreme weather, but also lead to health problems and premature deaths in its own country. Also, the cars manufactured without environmental regulations in the US may be cheaper for domestic buyers in the short term, but will not be sold in other markets without meeting their respective environmental regulations and requirements. So, what will business leaders in the automotive industry do: enjoy the temporary pain relief to make the balance sheet cleaner, or move forward to the future trend in the bigger picture? They may also be wondering which wind will blow in the next election in 2028, the blue or the red.

Global warming forced scientists to change the way they look at El Niño
El Niño, meaning “the little boy” in Spanish, and La Niña, “the little girl”, are two opposing climate patterns that break these normal conditions. El Niño occurs when the normal east-to-west trade winds that push warm water toward Asia weaken or reverse, and warm surface water from the western Pacific moves eastward towards South America. This prevents cold water from rising to the surface, upwelling, near South America, making the central and eastern Pacific become much warmer, and changing rainfall patterns and influencing global weather. When the trade winds strengthen, the opposite phenomenon occurs, La Niña. El Niño and La Niña events occur every two to seven years but not regularly, and they last nine to 12 months, sometimes for years. In the last three decades, these phenomena have been detected by comparing the ocean temperature in a specific part of the tropical Pacific. But as global warming has raised the temperatures of the whole tropical Pacific, the anomalies have become harder to see. Now, scientists subtract the temperature anomalies in the rest of the tropical Pacific from those in the region most important for El Niño. This update is just like replacing the old glasses with newly prescribed ones. With upgraded glasses, scientists can now see the changes in ocean temperatures earlier and better, and forecast long-range weather more accurately.

How the sound of sport is being reimagined for deaf fans
Just like the Olympic Games and FIFA World Cup, an international sports event is held every four years for deaf athletes, called The Deaflympics. Last November, its 25th Summer Games took place in Tokyo, marking the 100th anniversary of the event. The event featured 21 sports, including athletics, football, swimming, basketball, cycling, golf, handball, judo, shooting, tennis, and wrestling. The Deaflympics is also regarded as an important testing ground for inclusive technologies, where users and providers meet and work together to enhance sports experiences. One technology that helped the spectators feel the vibe was onomatopoeia, words that imitate, resemble, or suggest the natural sounds associated with objects or actions, such as Bang, Splash, Smash, Click, Beep, or Meow. The AI-driven, visual, and multilingual sound-recognition technologies were used to help Deaf and Hard of Hearing (DHH) viewers experience the stadium atmosphere with onomatopoeia in their languages. Also, at judo events, spectators who wore special vibration devices felt the players’ movements captured by microphones and sensors in the mat. Now, sound is no longer just heard, but can be read and felt.

Gender pay gap won't close for another 30 years, warns trade unions group
In the UK, the Equality Act 2010 entitles individuals to equal pay for "like work," work rated as equivalent, or work of equal value. The act protects against unfair treatment based on age, disability, marriage, race, religion, sexual orientation, and gender. However, according to a trade union, despite a slow, long-term downward trend, there is still a considerable pay gap between men and women in the UK. On average, men are paid 12.8% more than women by UK companies with more than 250 staff in the same industries. The gender pay gap is equivalent to a month and a half of the annual pay. Though the gap varies by industry, like 27% in finance and insurance, 17% in education, and 13% in health, it still exists across the board, both in full-time and part-time. Also, the widest pay gap is seen among workers in their 50s. The union attributes the cause to the long-term effects of women pausing or reducing their career opportunities for childbearing and caring responsibilities. In the meantime, the total fertility rate of the UK is now around 1.4, far below the reproduction level of 2.1. It seems essential to improve not only protections for expectant and new mothers, but also parental leave for both parents to reduce the gender pay gap while increasing the fertility rate.

China has another solution to its shrinking population: robots
Thanks to the massive workforce, gigantic market size, and the government’s initiatives, China’s economy grew rapidly in the last two decades and has become the world’s second-largest economy, only after the USA. Those who have contributed to the growth are now, or soon, retiring and aging. They will need care sooner or later. Traditionally, children took care of their parents in China, but things have changed as many of them work away from home for opportunities. Also, even after the removal of the decades-long one-child policy, China’s total fertility rate has fallen to around 1.0, well below the 2.1 reproduction level. As a result, its population declined by more than 3 million last year. How will China maintain economic growth and provide care to aging seniors with a smaller workforce and population? One solution is already there. Robots. In fact, China is the world’s largest market for industrial robots, with over half of all robots worldwide. Industrial robots are key to improving productivity and increasing production output. Also, China is keen on humanoid robots, which could help or replace humans in factories, distribution, stores, restaurants, and care services. As the capabilities and productivity of these robots and humanoids are further enhanced by AI, they are expected to mitigate China’s population and demographic issues, even though they may replace the existing workforce or reduce employment opportunities until humans re-skill or up-skill themselves to the new environment. So, it seems that the timing and speed of transition, replacement, and reinforcement are the key to coping with China’s demographic and social challenges.
