I received a call today asking if I would be willing to bring food to a family in need. The mother was having a major operation and would be lying down for several weeks. Of course, I responded with an immediate “Yes!”. As I planned the meal in my head, I reflected on how many times over the years I had been asked to prepare food. I have done so countless times with a very open heart.

    But the truly amazing thing is that I have received double over the course of my life. When my mother passed away, our house was filled with fresh dinners for weeks. A woman from the church of our community stopped by each evening with some food. The gift of food was her small way of trying to ease our pain.

    Later in my life, when I was on bed rest during my pregnancy with twins, women of the church again stepped in to help. They arranged babysitting for my two-year-old daughter, and brought lovely dinners to our house. Even when I was put in the hospital, my husband would bring cooked meals to my hospital room. How we relied on these dinners to feed my tired husband and young daughter.

    Food is all about comfort. It feeds our bodies, but it can also feed our souls. When you hear people talking about their favorite holidays, it usually includes their feelings connected with sharing food. I know that I will have many more opportunities in my lifetime to prepare food for others. It is truly a gift I want to prepare and deliver to someone in need.

    For many people around the world, a subway journey means speeding from one dull station to the next, surrounded by too many uncomfortable, impatient people. But on the Moscow Metro, taking the subway is like walking through a national heritage site. Depending on where you get off, you'll receive a brief course in architectural movements and face colorful glass windows, marble(大理石) columns, gilded(鎏金的) mosaics and painted scenes from Russian history.

    “These extraordinarily beautiful places are unlike any metro station I've ever seen, “says Vancouver-based photographer David Burdeny.

    When Burdeny, who himself has a master's degree in architecture, first found out about Moscow's metro stations, he was struck by the work of art. In all, he has photographed 20 of the most beautiful stations.

    Burdeny had originally planned to focus on Russian stations more generally, taking photos of examples in both St. Petersburg and Moscow.

    “But when I saw the stations in Moscow, they just completely blew away the St. Petersburg ones,” he says.

    Shooting in the subway sounds simple, but it is not without challenges. For one thing, Burdeny had to figure out a way to access them between 00:30 a.m. and 5:30 a.m., when the stations were closed.

    In the end, he settled on Arbatskaya Metro Station, whose vaulted(拱状的) arches he found the most beautiful. But it also represented a challenge he was not sure if he was able to overcome: conveying the hugeness of the spaces. The Arbatskaya platform, for example, stretches 820 feet.

    “Some of the arches are quite long,” he says. “When you enter them, they're just so completely grand.”

    If Frida Kahlo（1907-1954） is today one of the best-known and most popular figures of 20th-century, Mexican art, it is undoubtedly because of her personality and the originality（独创性）of a body of works. Her work is, above all, the expression of a real life－a tragic and stormy life, one that challenged all conventions. The mere mention of her name excites enthusiasm and admiration, but her work is rarely exhibited, and has not been shown in France for fifteen years. The selection to go on show at the Musee de L'Orangerie includes major works by the artist, with masterpieces from the Museo Dolores Olmedo.

    The life and work of Frida Kahlo cannot be separated from those of her companion Diego Rivera（1886-1957）. Together they became figures of legend, and both have a place in the pantheon of 20th-century Mexican artists. Famous for his large wall paintings, Rivera's easel paintings, drawings and prints, which form a large part of his artistic production, are less well-known to the public in Europe. The exhibition aims to trace his artistic career from the early Cubist images, revealing his links with the Paris artists whose works are a key element in the Orangerie collections, to the paintings that established him as the founder of the 20th-century school of Mexican art. His travels throughout Europe influenced his vision and his skills without ever distancing him from his roots, thus confirming his place in history as the founder of the nationalist school.

    The exhibition devoted to the legendary couple Diego Rivera and Frida Kahlo presents their works together, as if to confirm the impossibility of their divorce that was in fact finalized（定下来）but reconsidered after just one year apart. It also gives us a better view of their respective artistic worlds, so different and yet so complementary（互补的）, through the deep-rooted attachment they shared to their country.

    You often can choose a private setting when you browse(浏览) the internet. But be forewarned: It may not afford nearly as much privacy as you expect. That's the finding of a new study.

    Major web browsers, such as Google's Chrome and Apple's Safari, often a private-browsing option. It's sometimes referred to as “incognito.” This option lets you surf the Internet browser and saves a record into its history of each page that you visited. And what sites you visit won't affect the suggestions your browser makes the next time you're filling out an online form.

Many people believe—incorrectly— that the incognito setting protects them more broadly. Most believe it even after reading a web browser's explanation of the incognito mode.

    For instance, a new study had 460 people read web browsers' descriptions of private browsing. Each person read one of 13 descriptions. Then the participants answered questions about how private they thought their browsing would be while using this tool. The volunteers didn't understand the incognito mode. This was true no matter which browser explanation they had read. The researchers reported their findings on April 26 at the 2018 World Wide Web Conference in Lyon, France.

    More than half of the volunteers thought that if they logged into a Google account through a private window, Google wouldn't keep a record of their search history. Not true. And about one in every four participants thought private browsing hid their device's IP address. That's wrong, too.

    Blase Ur was one of the study's authors. He's an expert in computer security and privacy in Illinois at the University of Chicago. Companies could clear up this confusion by giving better explanations of the incognito mode, his team says. For example, the browsers should avoid vague（模糊).The web browser Opera, for instance, promises users that “your secrets are safe.” Nope Firefox encourages users to “browse like no one's watching.” In fact, someone might be.

    We've all had cases where we've waited just a bit too long to pay an electric bill or speeding ticket. But one man, from California by reasonable assumption, who goes by "Dave", recently took procrastination (拖延) one step further, by paying a parking ticket almost a half-century after it was given.

    In December 2018, the Minersville Police Department in Pennsylvania received a letter in the mail. Whoever wrote the letter decided it was best to keep his name somewhat unknown, so he put the return address as "Wayward Road, Anytown California" under the name "Feeling guilty".

    When the officers opened the envelope, they found a brief letter, along with a $5 bill, and a parking ticket dating all the way back to 1974. The note read, "Dear PD, I've been carrying this ticket around for 40 plus years always intending to pay. Forgive me if I don't give you my info. With respect, Dave."

    Even though the initial parking ticket was only for $2, "Dave" must have felt awfully guilty because he left 150 percent, or $3, in interest.

    Michael Combs, the Police Chief of the Minersville Police Department, stated in an interview that the same ticket would cost about $20 if it were given today. Combs went on to share that the original ticket from 1974 was given to a vehicle that had an Ohio license plate.

    Because there was no system for tracking tickets given to out-of-state cars back then, "Dave" could have gotten away with never paying the $2 fine. But apparently, guilt got the best of him, and he decided to finally cough up the money more than 40 years past its due date.

    Throughout history scientists have risked their health and their lives in their search for the truth.

    Sir Isaac Newton, the seventeenth century scientist, was very smart, but that didn't stop him from doing some pretty stupid things. In his laboratory in Cambridge he often did the strangest experiments. Once, while testing how light passes through lenses (晶状体), he put a long needle into his eye, pushed it to the back, and then moved it around just to see what would happen. Luckily, nothing long-lasting did. On another occasion he stared at the sun for as long as he could bear, to discover what effect this would have on his sight. Again he escaped suffering permanent damage, though he had to spend some days in a darkened room before his eyes recovered.

    In the 1750s the Swedish chemist Karl Scheele was the first person to find a way to produce phosphorus (磷). He in fact discovered eight more chemical elements including chlorine (氯), though he didn't get any praise for them. He was a very clever scientist, but his one failing was a curious habit of tasting a little of every substance he worked with. This risky practice finally caught up with him, and in 1786 he was found dead in his laboratory surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.

    Eugene Shoemaker was a respected geologist. He spent a large part of his life studying craters (火山口) on the moon, and how they were formed, and later did research into the comets of the planet Jupiter. In 1997 he and his wife were in the Australian desert where they went every year to search for places where comets might have hit the earth. While driving in the Tanami desert, normally one of the emptiest places in the world, another vehicle crashed into them and Shoemaker was killed on the spot. Some of his ashes (骨灰) were sent to the moon aboard the Lunar Prospector spacecraft and left there — he is the only person who has had this honor.
