1 . In many cultures, it is considered unlucky to spill salt. Fortunately, many cultures also have a solution to the problem, which usually involves throwing a pinch of salt over your shoulder. It may seem confusing to modern humans, but knowing that salt was once incredibly valuable can change this perspective.
For thousands of years, salt was an extremely rare commodity. It was difficult to obtain so that the price was very high. Many trading routes were set up to carry salt, people were paid in salt, and salt was sometimes worth more than its weight in gold. Therefore, spilling salt was considered wasteful.
Because of its high value, salt was also associated with friendship and good fortune. Offerings of salt were included in many religious ceremonies, and people might bring salt to a new home for good luck. These associations would have suggested that it would be bad luck to spill salt, since it would seem to violate salt’s fortunate properties.
Salt is also an excellent preservative. It prevents food from going bad. As such, it came to be linked with health and longevity. In some cultures, spilling salt was thought to reduce one's well-being. In Britain, for example, each spilled grain was said to represent a tear, while in Germany spilled salt awakened the devil, bringing misfortune.
The fear of spilling salt was also adopted into the Christian faith. It is said that Judas spilled salt at the Last Supper, and since he later turned out to be the betrayer of Christ, spilled salt is considered unlucky by many Christians.
Should you be unfortunate enough to spill salt, you might throw a pinch over your left shoulder to blind the Devil.

2 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.
Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.
In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.
The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.
The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.
So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.

3 . I woke up with drool (口水) on my pillow this morning. The alarm clock rang, and I reached over to turn it off. As I laid my face back down on the pillow, I felt the wet drool on my pillow case. I opened my eyes and saw a smiling, panting (喘气的), furry face gazing down at me. I tried to get up, but she was too fast. My face was suddenly covered in kisses with one going straight up my nose and another right in my ear. I laughed, reached out and picked up the eight-pound love machine and held her away from my wet face. It was just another morning in a life with dogs.
Why do we welcome them into our homes and our hearts? We know that most likely we are going to outlive them and have our hearts broken when they age quickly and pass away after ten to fifteen years. We know that there will be vet bills, flea baths and enough fur to make a vacuum cleaner cry. We know that our ears will ring from the barking, that we will be picking up the animal waste every single day and that we will never get to finish a full sandwich again.
Yet, when we are feeling down or blue, there will always be a soft head on our lap needing to be pet. When we get home after a long day’s work, there will be a happy face at the door waiting for us. Our lives will be full of balls to throw, bellies to scratch, and love and loyalty that will warm our hearts and uplift our souls.
For thousands of years, dogs have been our best friends. They remain one of the greatest gifts life has ever given us. Even if they can’t love us for the rest of our lives, they will always love us for all of theirs.

4 . Experts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors in Bristol cared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”
The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive sight loss.
He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it really arduous to read, watch TV or recognize faces.”
Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too many certain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”

5 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.
Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.
Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".
There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.
The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.
The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.
However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

6 . In honor of National Writing Day in the UK, actor Benedict Cumberbatch sat down at a desk and with the wisdom of his 39 years, he penned a letter to Santa Claus. You can read the letter in full—including the one gift the actor still really wants—below.
"Dear Father Christmas,
Like most adults I feel embarrassed asking anything of you because our time with you is surely gone. Now we get our own presents, take responsibility for our own actions, and live in the world we have created. So it's not for us to turn around and ask for your help with the environment, education, food banks, human rights and wars. Though we need all the help we can get with all these man-made problems.
And it's not that you're not kind-hearted. You're great because you are for the children who need some magic in a world where playful imagination and innocence(纯真)are decreasing.
This is what I'd like to ask you to help with. A little more time for children to be children. Lengthening the moment of magic and playfulness. Keep them away from the realities of a world that's gone mad, especially those suffering illness or hunger or shaking with fear or cold because of environmental disasters or wars. Please help to light up their worlds with a moment of joy and hope.
You do inspire wonder among those who write you letters and go to sleep hoping there might be a new object in their possession coming down. You inspire good behavior.
I feel a little sorry. And I guess I've done exactly what I said I wouldn't... Asked you to help with adult problems and solve some of the greatest worries we have for our children. I promise to leave some delicious pies for you!"

7 . Chinese audiences on average spent more time watching entertainment content online in this uncommon year when the battle against COVID-19 is still being fought.
An average consumer has spent 133.9 minutes each day watching TV dramas, a 10 percent increase compared to last year, according to the report. Interestingly, TV romantic dramas make up 36 percent of all 131 new television series this year, ranking the first.
In the overseas market, Chinese dramas are seeing a rise in popularity, such as hit costume dramas Three Lives Three Worlds, The Pillow Book, and The Romance of Tiger and Rose. The report shows that subscribers (订阅者) of WeTV, the overseas version of Tencent Video in more than 110 countries and regions, have risen 175 percent over last year, with time spent watching these programs up 300 percent year-on-year.
Shows with strong female roles are more popular, like the hit series Nothing but Thirty, I Will Find You a Better Home and A Murderous Affair in Horizon Tower, the report said. It also found that a quality trailer (预告片) played an important role in drawing an audience, as about 90 percent of consumers pick their choices from trailers.
As a result of the six-month shutting down of Chinese cinemas, a number of people have chosen watching films online.
Through Nov. 30, a total of 15 online films have earned more than 10 million yuan, propelling the annual box office income on Tencent Video to nearly 500 million yuan this year. While TV series are almost "dominated" by female audiences, men are favored online movies more. Nearly 70 percent of online film viewers are men, whose favorite themes center on fantasy, comedy and adventure.

8 . A road running through Accra, Ghana's capital, looks like any other blacktop（柏油路）. Yet what most drivers don't realize is that it is made from plastics—melted bags, bottles, and snack wraps--that otherwise would have ended up in a landfill.
In a developing nation, “it's difficult to recycle plastic,” noted Heather Troutman, program manager of the Ghana National Plastic Action Partnership. “It's expensive, and much easier just to burn it. But if you could put value on recycled plastic, it won't get buried or burned.”
First appearing two decades ago, plastic roads are being tested and built in more and more countries as the world's plastic pollution problem becomes more serious. India has built over 60,000 miles of these roads. The technology, meanwhile, is gaining ground in Britain, Europe, and Asia. Several countries—South Africa, Vietnam, Mexico, the Philippines, and the United States, among them—have built plastic roads recently. Roads containing waste plastic have the potential to perform as well or better than traditional roads. They can last longer, are stronger and more durable（更耐用的）in respect to loads, car tolerate wide temperature changes, and are more resistant to water damage and cracking.
Troutman views plastic roads as “a promising advance,” especially in a country like Ghana with more road projects in the future. And yet, with the prediction that by 2050 the world will produce over three times as much plastic waste as it ever has, she stresses it is vital to curtail Ghana's all unnecessary use of plastics. “This is the first step,” she noted. “If we keep pumping out more and more plastic, we'll never be able to manage it in a sustainable way.”

9 . The over 48,000 orange trees that are distributed at all corners of Seville, Spain, not only fill the city's air with the pleasant smell of their flowers in spring, they also produce over 16, 500 tons of fruit every winter. Though that makes the city Europe's top orange-producing city, the fruit is too sour to be consumed fresh. While some of the produce is used to make orange juice, most of it ends up in Seville's landfills. However, that may change soon thanks to a creative idea to use the oranges to produce clean energy.
In the pilot program, juice from 38. 6 tons of oranges will be left to ferment (发酵)in an existing biogas facility. The juice is fructose (果糖)made up of very short carbon chains, and the energetic performance of these carbon chains during the fermentation process is particularly high. The gas released from the fermented liquid will be used to drive a generator to produce clean power. The officials estimate the test run will generate about 1,500 kWh of energy—enough to run a water purification plant. "It's not just about saving money. The oranges are a problem for the city, and we're producing added value from waste,M said Benigno Lopez, the head of Emasesa's environmental department.
If successful, by 2023, the city hopes to recycle all the oranges and add the electricity generated back to its grid (电网). In trial runs, 1,000 kilos (2,200 pounds) of oranges produced 50 kWh of clean energy一enough to meet the daily electricity needs of five homes. The project team estimates that if all the fruit is recycled, it will produce enough energy to power as many as 73,000 residences.
The latest effort is among the many programs implemented in Spain to achieve the country's goal of switching its electricity system to renewable sources by 2050—and if everything goes according to plan, fully decarbonizing its economy shortly after that.

10 . JeffBezos has a rule at Amazon, or perhaps more appropriate a philosophy. If a team cannot be fed by two pizzas then that team is too large. The reasoning is quite straightforward and basic. More people means more communication, more bureaucracy, more chaos, and more of pretty much everything that slows things down, hence why large organizations are oftentimes considered as being so inefficient.
In 2013 Gallup released a report called “The State of The American Workplace", in which they found that smaller companies had more engaged employees. In fact,42% of employees working at companies of 10 or fewer were engaged at work versus only 30% of employees at large companies.
Most people are not familiar with the Ringelmann Effect which is the tendency for individual members to become less productive as the size of a group increases. This concept was named after Maximilien Ringelmann, a French professor of agricultural engineering who passed away in 1931.In one of his experiments he asked volunteers to perform a very simple task, to pull on a rope. He found that when only one person is pulling on the rope they give 100% of their effort; however, as more people are added the individual effort goes down.
This experiment was recreated in the 1970's by Alan Ingham who came up with the concept of “social loafing” which helps us understand why the individual effort decreases as the team size increases. So why does this happen? Because it becomes harder to extract the individual contributions and performance of each person.
Organizations should really think about what their team structures look like and create and follow similar “two pizza rules”. It's no coincidence that smaller organizations are oftentimes more nimble while large organizations look like they are stuck in the mud.
