1 . Pieter Bruegel’s 1565 realistic painting The Harvesters hangs at the Metropolitan Museum of Art. “The work describes farmers cutting wheat nearly as tall as they are,” Ghent University biologist Ive De Smet says. “Nowadays, if you walk through a wheat field, you basically see wheat is about knee-high, which is a consequence of selective breeding (培育) from the second half of the 20th century.” De Smet says he’s teaming up with art historian David Vergauwen of Amarant to look at things where they can spot differences in shape, in color, and in size. Wheat is just one example of how historical artwork can help track the transformation of food crops over time.

Friends since childhood, they took interest in plants in artwork and began with a visit to the Hermitage Museum in Russia — where they noticed an odd-looking watermelon in an early-17th-century painting by Flemish artist Frans Snyders.

“So if you think of a watermelon, you cut it through, it should be dark red on the inside. But that one appeared to be pale and white.” De Smet assumed the painter had done a poor job. But Vergauwen said, “This is one of the best painters ever from that era. So if he paints it like that, that’s the way it must have been.” Other paintings showed that both red and white watermelons were raised during the 17th century.

The team hopes to set up an online research database of historical plant artwork. They create a social media hashtag (主题标签) for it. Anyone could send pictures of relevant artwork and details of plants when they visit a museum or exhibit through the hashtag. But, they add, the sources need to be realistic. “If you’re going to use, for example, Picasso to understand how a pear looked, you might be misled.”

2 . I had not hugged a friend or a family member for more than two years until recently when my sister flew in for a brief visit. For safety, we met outside. Despite the wintry weather, her hug warmed me from the inside out. It’s strange, but only now do I truly realize how much I’ve missed embracing loved ones.

I grew up through war in my hometown of Sarajevo, Bosnia, and every moment was full of danger. On one peaceful morning, I had begged my mom to let me go outside after spending weeks indoors. She finally agreed. I was outside for only 10 minutes when I was caught in an explosion. I ran to my neighbor’s house for safety and hung my arms around her neck just as my legs collapsed underneath me.

Thankfully, I made a full physical recovery, but the emotional scars never left me. Years later there was another explosion near my house. I was safely inside, but my father had left to buy a loaf of bread. He had only just missed the explosion. When he came back inside, I gave him the biggest hug imaginable. I was caked in tears as I held him tight.

That same night my parents managed to arrange my escape from our war-torn city. I was 16 and came to America on my own. A generous host family took me in. They had a large dog called Oscar. Over the next several months, I secretly struggled with feeling homesick and worried about my family back home. Despite managing quite well at school, I couldn’t express my feelings. The only way I shared how I felt was by giving Oscar a big hug.

It is yet another sad aspect of our pandemic(疾病大流行的) lives that hugging a stranger is the last thing on our minds. For many of us, even hugging a relative or a friend comes with stress and anxiety over risks and precautions. As I look back on my past, I count myself truly lucky to have been held, shielded and encouraged at some of the most key moments of my life by the power of a hug.

4 . Snowboarding genius Su Yiming made a name for himself by winning China’s first Olympic gold in the sport on Tuesday. By cleanly stomping back-to-back 1800 tricks, the teenager landed the biggest prize so far in his young career—gold in the men’s Big Air at the Beijing Winter Olympics. The notable achievement realized a childhood dream to reach the peak of the sport, which he began to learn at the age of 4.

Now with two shinning medals hung around his neck, the 17-year-old described his superb Olympic debut ( 首秀) as an unbelievable experience that has made all his sacrifices worthwhile. “This feels so surreal that I’ve finally accomplished what I’ve dreamed of since I was little,” said an emotional Su.

Over the past four years, Su has combined his talent with hard work to produce one of the swiftest rises to prominence the sport has ever seen. When the Shougang Big Air venue hosted its first international event, Su was an unknown qualifier, who didn’t even make the final runs. Just over two years later, Su is the name on everyone’s lips at the venue’s Olympic debut—drawing the whole nation’s attention to the sport he loves.

“The biggest motivation (动力) for me is my love for snowboarding,” Su said, when asked about the secret to his success. “In snowboarding, I feel like I can show my own style and creativity. Every time I ride my board, it’s always a joyful moment. I hope through my experience, I can inspire more young people to get interested in the sport.”

Su, a former child actor who featured in action movies, said the Olympic gold will encourage him to seek for more breakthroughs—even beyond his athletic career. “I enjoy snowboarding just as much as I enjoy acting,” said Su, who turns 18 on Friday. “I think I still have a lot of possibilities to explore in my future career either in snowboarding or in acting. But now I just want to enjoy the moment and celebrate it as the best possible birthday gift.”

Going to a boarding school is a new experience full of excitement of the unknown. Socialization is a big thing for students and it is common to feel a little uncomfortable going into a situation where everyone is a stranger. You may probably miss your friends from former school. Trying actively to find new friends can help ease the feeling of being lonely. A boarding school is a great chance to make new lifelong friends. The question is: How?

    1    

You may find you have lots of things in common with your roommate，but even if you are completely different from each other, with a little effort and understanding, the two of you may become best friends.

    2    

If you leave your door open，this shows that you welcome visitors. As a result, people will naturally stop in and say hello. Closed doors are not likely to bring many visitors and those who stay locked up in their rooms may give others the impression of being cold. Other students will be less likely to stop in and build a new friendship.

    3    

Getting involved in organized socialization is a great way to meet new people. It also helps you get more familiar with the campus. By staying active in school groups such as clubs and organizations, you can meet lots of people with whom you share common interests.

    4    

Get to know your classmates as you’ll be spending several months with them. Starting conversations in class is a great way to meet people who are interested in the same kind of studies as you are. Short friendly discussions can build lifelong friendship.

    5    

If you’re athletic, trying out for a sport will do for you the same thing as joining a club will do. You will instantly meet a large group of people who share your interest in sports.

7 . If you cut in line, you might just be a bad person. The queue is a regulation where the reward (the ice-cream stand/dining room/ticket booth) is earned through patience. Your choice to avoid this time-honored process will be bound to draw the anger of those you pass by, drawing remarks like “Whoa there, Chief,” the passive-aggressive “There’s a line, you know!” and of course, the incredibly common “Hey, Copernicus, why don’t you guide yourself to the back of the line?”

But, in the moment in which you really cannot wait, for example, the entire royal family has prepared a dinner party upon you last minute, then there is a way to cut the line correctly.

There are a few different ways to consider and a few different methods to employ. The regularity of the situation is very important. If you’re waiting to use the photocopier at work, you might be more likely to manage a successful cut than if you were waiting for a lifeboat on the Titanic. Sure, that might be an extreme example. But the importance of the event does matter.

For those requests in normal situations, emphasizing either the urgency of your task or the simplicity of your task proved to be effective: experimenters who said “Excuse me, I have five pages. May I use the photocopier?” had a cut rate of 60 percent and experimenters who said “May I use the photocopier because I need to make copies?” saw a success rate of 90 per cent when queuing for the copy machine.

If you have a couple of extra dollars lying around, bribing members of the line also proved to be effective. And most of the time, the person being bribed didn’t end up accepting the money, because even the offer showed that the briber had a sense of desperation.

9 . Jules is now in his sixties, and is one of the many homeless people who live on the streets; he buys a newspaper most days. Today, with his fellow tramps, he reads about yesterday's student demonstrations.

Like many of the tramps who live under the bridges, Jules was not always so poor. A long time ago he was in the Navy, and like many who have been to sea for a long time, he has stayed slim and fit. Despite the strict organization on board ship, he loved his life, and had the opportunity to see many countries. He visited Poland and Russia; in South Africa he realized what he valued in each country was the people he met. He was always astonished and delighted by the ways in which the people he met differed from one country to another. Some day, he hopes, everyone will see the world as he does.

After many happy years in the Navy, he had to retire. The good things in life always come to an end. His mother and father had long since died and he’d lost touch with his other relatives. He became an industrial designer. He was happy, although it wasn’t the same as the sea. He never wanted to get married and have children.

And then there was the period of darkness. He smiles sadly. He shrugs his shoulders and looks at his hands. There are tears in the corners of his eyes. This is something that he cannot bring himself to talk about. ''It all went wrong, '' he whispers.

He was silent for a while, then recovered. He began to talk more loudly. ''Look at me now---it makes me angry. And what about the President? He's been in power for years, and look what he's done for us. Nothing! I am still out on the streets and live the life of a dog.''

10 . Summer is here, and with it comes a chance you'll get too much sun. While there's no cure for sunburn, a small but fascinating new study suggests taking large amounts of vitamin D after exposure may prevent the associated redness and inflammation (发炎).

In the paper, researchers exposed 20 volunteers to a light resembling solar radiation to induce a sunburn on a small piece of skin. They then gave the ''burn victims'' large amounts of vitamin D, and followed up with participants one, two and three days (and a week) later to measure skin redness and thickness. The researchers found that vitamin D decreased inflammation and redness, compared with taking a placebo (安慰剂). And this effect increased in proportion to how much was consumed. Vitamin D also appears to increase the activity of a gene called arginase-1, which is involved in tissue repair and healing. Taking 50, 000 international units (IU) of vitamin D--125 times the recommended daily allowance-led to a significant reduction in redness and inflammation, compared with the placebo. Those who took 100,000 IU had even less redness and pain; and those who took 200, 000 IU had the greatest reduction in inflammation.

This is the first study to show vitamin D can reduce inflammation, and suggests that it   ''could potentially help prevent sunburn, '' says senior author Kurt Lu, a physician scientist and assistant professor at Case Western Reserve University.

It used to be thought vitamin D was primarily involved in building healthy bones and muscles, but recent research has found it has many more roles, including influencing inflammation, such as the kind associated with sunburns.

So, if you get burned, should you take a lot of vitamin D? The study authors don't recommend it. ''I think that's probably not a good idea and not well established by this study, '' says Barbara Gilchrest, a physician scientist at Massachusetts General Hospital. Such large amounts, if taken repeatedly, have the potential to cause vitamin D toxicity (毒性).
