Dear MEL Topic Readers,
Biased and wrong? Facial recognition tech in the dock
What is face recognition, or FR? It is a method of identifying or verifying the identity of a person by the images of their faces. Face recognition systems use computer algorithms to pick out specific, distinctive details about a person’s face, such as distance between the eyes or shape of the chin. Then, they convert the information into mathematical data and compared with data of a face recognition database. Facial data can be collected from social media, Closed-circuit Television (CCTV), traffic cameras, published or private photos, or organizations’ database without being recognized by the person. So, if the face of a known terrorist is captured by security cameras in a public place like an airport or station, face recognition system alerts the authority for attention or action. It surely saves time and could save lives.
However, how reliable face recognition technology is? Unfortunately, it varies by situation and object. The angle and brightness of the image, and the skin color and gender of the object all affect the accuracy of the identification system. Also, there are technical difficulties that are unique to machines. For example, differentiating photos of a blueberry muffin and the face of a chihuahua dog isn’t an easy task for facial recognition.
Some authorities use FR aggressively to identify criminals, unwanted or suspicious people in public places. In fact, there are hundreds of millions of CCTV cameras installed in China. On the other hand, law enforcement agencies of San Francisco are banned to use facial recognition for fear of threatening civil liberties and making false alerts.
Is technology always flawless, or close to perfect? Which is more reliable, human eyes or AI-powered face recognition?
Enjoy reading the article and think if you feel more secure in an airport with face recognition security system.

Amazon at 25: The story of a giant
Born on July 5, 1994, in a Seattle metropolitan area in Washington, Amazon celebrated its 25th birthday this month. The company initially sold books at its online marketplace and later added electronics, CDs and DVDs, games, apparel, groceries and toys to its offering. Just in five years, its sales surpassed well over the one-billion-dollar mark. The rapidly growing online giant retailer opened its distribution services to small businesses, introduced prime membership and subscription services, launched electronic reading and smart devices, started on-demand cloud computing platforms, and stepped into brick-and-mortar retail business. Now, Amazon is the world’s largest online retailer and internet company and US’s second largest employer and technology company by revenue. It is now one of three most valued companies with Microsoft and Apple, which made the founder and chairman Jeff Bezos the wealthiest person in the world, who just made the world most expensive divorce settlement.
What Amazon will be doing in the next 25 years? Will we see extraterrestrial delivery services by amazon spacecraft? That might not be in the not so far future.

Dear MEL Topic Readers,
Destination trouble: Can overtourism be stopped in its tracks?
With rising middle class, increasing budget airlines and massive cruise liners, and influencing travel websites and social media, tourism has been flourishing for the last few years. In 2018, there were 1.4bn international tourist arrivals, according to the World Tourism Organization (UNTWO), a rise of 6% over the previous year. Some of the popular travel destinations are visited by more tourists than the local residents daily. Although tourists bring and spend money that creates jobs and boosts the economy, too many visitors could cause trouble to local communities. Indeed, overtourism is becoming a major problem to popular tourist destinations, and they are trying to find a way to balance tourist demand with the peace and life of the local community. Some cities like Venice, Italy have started levying entrance fees to day trippers who tend not to spend so much money. Such tourist tax varies by season to reduce peak-season visitors and boost slower-season visitors. Others like Amsterdam, Netherlands, and Reykjavik, Iceland are promoting other cities in their countries to divert tourists. To maintain order, Rome, Italy now bans bars to serve alcohol between 2 am and 7 am and fines people who drink in the street after 10 pm.
Overtourism seems to be another case of imbalance between the economy and the environment.

A group of US billionaires is calling for a wealth tax
Wealth tax is a tax on the total value of personal assets, such as money, bonds, stocks, real estate, cars (and boats and airplanes), valuable properties like antiques and paintings, pension plans, and unincorporated businesses. Poor people don’t have such assets. People of the middle-class may have just enough assets to get by for now, and hopefully for after retirement. Only the rich own more than enough personal assets to spend or waste, donate or give, or inherit or succeed at will. They usually try their very best to minimize taxes they have to pay.
Now, some very wealthy Americans are calling for a tax on their wealth to tackle climate change and reduce inequalities. They seem to be generous enough to institute such a progressive initiative trying to make changes. But not all the rich will agree with being levied more taxes as they already paid income tax, sales tax or inheritance tax when they obtained their assets. In other words, it’s double taxation. Also, there are non-financial assets that are unique and hard to value, such as vehicles, antiques, private business.
Will this move help solve the problems? How much additional tax burden can they bear?

Obesity 'causes more cases of some cancers than smoking'
The fatter a person is, the higher the risks for cancer are. And the risks become even higher if the person is overweight or obese for a longer period. Furthermore, those who are overweight or obese are more likely to suffer from cancer than smokers, according to a UK research institute.
Though the link between obesity and the biomechanisms is still yet to be known, the research shows bowel, liver, kidney, and ovarian cancers are caused more by obesity than smoking. However, smokers shouldn’t feel relieved by these research findings as smoking still is the top cause of cancer overall in the UK. The problem is while smokers are decreasing in number, those who are overweight or obese are increasing. And the potentially fatal problem is increasing child obesity. Indeed, they are obese for a much longer period than their parents.

What to drink to help you sleep
What do you avoid eating or drinking after dinner to enjoy a sound sleep? Those who are sensitive to caffeine try to refrain from taking caffeine-rich drinks like coffee, green tea, and some soda.
Then does sweet chocolate that you may find on the bed in your hotel room get you a sweet dream? Sorry. It also contains caffeine. You also need to brush your teeth again.
What about a nightcap? Milk, whether warm or not, might be of some help but definitely not alcohol. It only helps you fall asleep but disrupts your sleep quality.
One thing seems to be sure. None of the things in your hotel room, in the fridge or minibar, helps you sleep better but water. Yes, water. You certainly want to be adequately hydrated when you go to bed.

Assam NRC: Are India’s ‘unwanted people’ being driven to suicide?
Assam is a state in northeastern India known for its wildlife, archeological sites, silk, and tea. It is bordered by Bhutan to the north and Bangladesh to the south.
Recently, the state has been intensifying its effort to identify who are locals and who are not.  Those who migrated from its eastern neighbor Muslim-majority Bangladesh, or East Pakistan before its independence in 1971 may lose their citizenship. Four million people have already been excluded from the national register of citizenship list and many of them are feared to face either detention or deportation if they cannot prove their residence prior to 1971. It is a fatal blow to those who have already lived in the state for more than a few decades. They have nowhere to go once they lose their citizenship. Some of those in despair about their future have killed themselves. India was a dreamland and has been their homeland.
Is this just a sort of legal procedure or ethnic cleansing? Could the same thing happen to Hispanic Americans in the US?

Heatwaves: What you should and shouldn’t do to stay cool
Summer is coming in the northern hemisphere. If you are in an air-conditioned space, you need not worry about the heat and do whatever you like, such as reading a book, taking a nap or doing an exercise.

Second US town pays up to ransomware hackers
Ransomware is a malicious computer software that threatens to destroy someone’s files, systems, or even reputation unless a demanded ransom is paid. If not paid, the ransom goes up, or the threatened files or systems are encrypted so that the victim cannot use or access the data or use the system. At that point, the victim has only three choices, to pay the inflated ransom with a hope to bring the files and system back to life, to restore them from the backup only is such backup had been made, or to give up and rebuild everything from scratch.
Where there are risks, there also are insurance businesses. Cyber insurance is designed to help organizations to relieve or reduce risk exposure by offsetting costs for recovery after a cybersecurity breach. When a small town in Florida suffered downed computer systems for two weeks, they decided to have their cyber insurance company pay the ransom. The good news is the system came back to life after the payment was made and the cost was covered by the insurance. The bad news is that their insurance premium will go up unless they build a bullet-proof security system that convinces the insurer that future risk is lowered.
To avoid such disaster, never open attachment or links in unsolicited emails. Make sure to update your computer system. Keep backup files on an external drive or cloud service. Remember, every time a ransom is paid, it finances the attacker to be more demanding, malicious, and sophisticated.

The fiction that predicted space travel
Born in England in 1917, Sir Arthur Charles Clarke was a renowned science fiction writer. The stargazing child worked as a radio engineer during WWII and later became a science fiction writer, futurist and undersea explore in Sri Lanka.
His first novels were about space explorations, the first flight to the Moon and colonization of Mars both of which were published in 1951 during when the world was still stuck in the aftermath of WWII.
His most famous work, A Space Odyssey was written in 1968 when the world was divided by ideology and nuclear weapons. It was made into one of the greatest films of all time directed by Stanley Kubrick. The story was about encounters with an alien monolith that sparks a technological and intellectual leap, which was succeeded by three sequels, 2010: Odyssey Two in 1982, 2061: Odyssey Three in 1988, and 3001: The Final Odyssey in 1997.
Another famous alien encounter story is Rendezvous with Rama in 1973, whose sequels were published in 1991, The Garden of Rama and in 1993, Rama Revealed.
In these futuristic books, Clarke introduced iPad like communication and information device, computer software that reads human lips, space tourism, space elevators, and space stations.
Over a decade after his death, only a few of these have been brought into life. Humans still have a long way to catch up his extrapolations.

San Francisco becomes first US city to ban e-cigarettes
An electronic cigarette also called e-cigarette or vapor is a battery-operated device that emits doses of vaporized nicotine. Users of e-cigarettes can enjoy a similar sensation to inhaling tobacco smoke without smoke. Though the manufacturers claim that e-cigarettes offer a more healthful alternative to cigarettes, there is growing evidence that vaping may be harmful. It contains nicotine that is addictive especially to the young and hazardous during pregnancy. Also, the aerosol contains harmful solvents, flavorings, and toxicants.
The most alarming problem seems to be teenage vapers who tend to do what others do. With alluring assorted flavors, such as menthol, peach pit, vanilla, chocolate, and mango tango, along with fashionable packaging and cool brand names, more and more teenagers are attracted to this smoking alternative.
Now, San Francisco is going to prohibit sales of e-cigarettes in and delivery to the city. It sounds controversial because San Francisco is where Juul Labs, the most popular e-cigarette manufacturer in the US, is located. They claim that the ban will drive their customers back to their competitor’s products, traditional cigarettes.
Isn’t it like staring at smartphones instead of TV screens? Both are addictive. In either case, how do kids get money to buy a smartphone or vaper?

A guide to 4th of July for non-Americans
Yesterday, The United States of America celebrated its 243rd birthday. It declared independence from Great Britain on the fourth of July 1776 and became the first European colony to be recognized by the international community after the American Revolutionary War that ended in 1783. Other countries in the American continents followed suit and became independent in the next century, like Mexico from Spain, Brazil from Portugal, and Canada from Britain.
On the fourth of July, Americans celebrate their birthday party and enjoy ceremonial events across the country. Firework displays, parades, and barbeque parties, to name a few. Somehow, hot dog is the most popular food to celebrate this birthday, and over 150 million hot dogs were eaten last year, according to an industry organization. Actually, a single man ate 71 hot dogs in 30 minutes at the Nathan's Famous hot dog eating contest to defend his title.

Christchurch attack: New Zealand launches gun buy-back scheme
A gun buyback program purchases guns, and in some cases with ammunition, from private owners to reduce the number of firearms. Some programs also give the chance for those who own firearms illegally to surrender the weapons to the authority without prosecution
In Argentina, over 100,000 firearms were collected in the 2007-2008 buyback program, which was voluntary and anonymous.
In Brazil, more than one million guns were collected and destroyed in two programs between 2003 and 2009.
In Australia, as many as 660,000 firearms were retrieved and destroyed in a similar program in 1996.
New Zealand banned semi-automatic weapons shortly after the March 15 Christchurch massacre which left 51 victims. They’ve now launched a buyback program to collect as many as 14,300 licensed military-style semi-automatic weapons until December 20.
In any case, even though the number of guns on the streets is reduced at least for some period of time, the chance for another mass shooting still remains until the last gun is collected.

India to overtake China as the world's most populous country: UN
The world’s population was about 2.5 billion in 1950, six billion in 2000, seven billion in 2012, and 7.7 billion this year. So, there are over three times as many people now as were shortly after WWII on the planet. That is quite a leap in a very short period of time in Homo Sapience’s seventy-some millennium history. And the increase has been accelerated especially for the last two decades, which have added nearly two billion people. The world is surely getting more crowded especially in Asia and Africa.
And for the next three decades, the world is predicted to add two more billion people. The growth rate declines as over 50 countries are expected to lose their populations more than one percent mainly due to low fertility rate. China alone is going to lose 300 million people by 2050 due to the decreasing fertility rate that is caused by urbanization, later marriage, and rising living, especially education costs.
The growth is expected to come from other part of Asia, but not from eastern countries like Japan or Korea but from South and Southeast Asia like India, Pakistan, and Indonesia and also from Africa. For example, Nigeria, whose present-day population is about two hundred million, is expected to add more than half a billion people just in the next three decades.

Dogs' eyes evolve to appeal to humans
You know it.
Dogs often make an attention-grabbing expression or noise when they want their owner to do something for them, such as petting and feeding. You may take it for granted, but researchers found that such infant-like expression is a result of evolution over millenniums.
Since domesticated dogs no longer need to develop strong jaw muscles to bite other animals or tear the meat off the bone, they seem to have developed a muscle to raise the inner eyebrow over time instead to make a non-verbal appeal to humans, just like human infants do. Indeed, they seem to have learned such subtle and delicate, yet effective communication means to get along with, or even take advantage of human feeling.

Backlash grows against cashless society
Is cash still king?
In China, nearly 600 million people use mobile payment, such as Alipay and WeChat Pay that dominates over 90 percent of the market. In fact, the total number of transactions made via mobile payment platforms surged to 60 billion in 2018, up from 1.7 billion in 2013. People can buy mantou at a food stand, book a rideshare vehicle, make utility payments, or even pay a speeding fine. More and more people in large cities stop carrying their wallets when they go out.
In the US, six out of every 10 retail transactions were made in cash a decade ago but now it's only three in 10 transactions. More retailers prefer accepting only plastic or mobile payment to cash to save time and cost as well as to reduce the risk of robberies.
In Sweden, many banks abandoning handling cash as the Scandinavian country is moving towards a cashless society.
It seems that money control is shifting from banks to card issuers and mobile payment platformers. And this move gives convenience for both ends of the transaction. As a result, more retailers are accepting only non-cash payment. However, what about those who don’t have a plastic card, mobile phone, or bank account? Will they all be left out when no one accepts cash?

Located on the Coromandel Coast off the Bay of Bengal, Chennai, used to be called Madras, is the biggest cultural, economic and educational center of south India. With a population of nearly five million, it is the sixth largest city in India.
Chennai usually gets most of the seasonal rainfall during the monsoon season from October to December that refills water reservoirs. Since no major rivers flow through the region, Chennai suffered from massive floods during the monsoon season in 2015 that was caused the record-breaking rains in a century. But when there is little rain during the season, the city gets water shortage. And that is what happed in the last monsoon season. As a result, the city’s four major reservoirs are almost dried out after having no rain for nearly 200 days. Now people, businesses, hotels, schools and even hospitals get no tap water. They are solely depending on water tankers. Only large hospitals get priority for water delivery, but most others get rationed quota of water once a day or week. Many restaurants and hotels are closed for weeks. People have a hard time washing their dishes, bodies and even hands before a meal, which is hygienically problematic as people eat by hand.

In 2013, when a 20-meter-wide asteroid exploded in the skies over Chelyabinsk, Russia, the airburst caused shockwaves that smashed windows and injured 400 people.
Last year, a small asteroid called 2018 LA exploded over Botswana, Africa and a meteoroid of a size of 2-meter-across landed in thick grass, which was retreated after an intensive search.
Aren’t these asteroid impacts frequent and significant enough for human beings, and all the other earthlings, to worry about? If it had been Central Europe, not Siberia, what scale of destruction would have recorded in human history? People would not have had enough energy or resources to engage in WWI. What if the last year’s tiny meteoroid had hit Beijing or Washington DC instead of the grassland in Africa? The damage and casualty would have been beyond imagination.
In order to save earthlings from killer space rocks, a system of telescopes called Atlas is tracking objects flying around our planet. Once a potentially hazardous asteroid is discovered, astronomers begin plotting trajectories and predicting impact sites. When the asteroid comes close enough for radars, they can estimate the density of the object to predict landing area and the impact when it enters the atmosphere. Then an early warning could be issued to the people in the predicted area.
Is there any way to avoid such devastating impact?

Dear MEL Topic Readers,
Reading the tea leaves about whether drinking green tea is good for you
Originated in China, green tea is popular among Asian countries. Unlike black tea or oolong tea, green tea doesn’t undergo withering and oxidation process. Because of the abundant catechins, green tea has been believed to have various health benefits, such as preventing cancers and cardiovascular diseases, lowering fasting blood sugar, losing weight, and deterring cognitive decline. Is green tea really an almighty medicine or life-savor?
Unfortunately, none of such health benefits has been chemically or medically proven. However, that does not mean you cannot enjoy the flavor and taste of green tea. For example, what is an appropriate or ideal drink after a Chinese or Japanese cuisine, coffee or black tea with sugar and milk? Indeed, food and tea, like wine or sake, have long been evolved together. Also, there is undeniable relaxation benefit for having green tea, just like having a cup of coffee or black tea after a meal, during work or for a break.
The bottom line: you can certainly enjoy green tea without harm to your health.
Enjoy reading and learn about what green tea does or doesn’t do for you.

Dear MEL Topic Readers,
Is it time to treat sugar like smoking?
Plain tobacco packaging requires the removal of all branding, such as colors, imagery, logos, and trademarks, and permits manufacturers to print only the brand name in a regulated size, font, and place on the pack. The rest of the package’s area must be printed with, often severely discouraging health warning to deter smoking. In 2012, Australia became the first country to introduce plain packaging. In the UK, plain packaging became a requirement for all cigarettes sold after May 2017. In Asia, Thailand is becoming the first country to mandate plain packaging starting from September this year.
There is a more serious health problem in the UK. Obesity is now one of the leading preventable cause of death. More than one-third of men and over 8 in 10 women are thought to be overweight or obese, and by next year, the ratio is predicted to reach 90%. This serious weight problem has been increasing the number of deaths by diabetes, heart diseases, and cancers as well as medical costs. And children are no exception. They are constantly exposed to attractive sweets and sugary drinks, which often contains multiple times of recommended daily sugar intake per serving.
In order to make people think twice before opening the attractive package of a such-rich snack or twisting the cap of a sugary drink, a new move to introduce “discouraging packaging” is on the rise. Imagine a chocolate or candy bar wrapped in a plain package full of health warning with a plain brand name. For producers, it would be awfully difficult to market or promote new products that aren’t familiar to consumers. It would also be difficult for consumers to distinguish Coke from Pepsi.
Though it may sound too radical when the smoking ban in public places or plain tobacco packaging was first discussed, neither of which had been expected to pass Parliament.
Enjoy reading the article and think if the idea is a good step towards a sugar-free diet.
