    Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.

    Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting（收缩）and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.

    Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”

    The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see and guide whether we see fear.”

    To further understand this relationship, the scientists also used a brain scanner（扫描仪）to show how the brain influences the way the heart changes a person's feeling of fear.

    “We have found an important mechanism by which the heart and brain ‘speak' to each other to change our feelings and reduce fear,” Dr Garfinkel said.

    “We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those who may be suffering from serious stress disorder.”

    Machu Picchu is an unusual site in Peru and one of the most mysterious wonders of the world. Built at almost 10,000 feet on the top of an Andean mountain, the Incas built hundreds of structures made of stone. A large number of Machu Picchu's surrounding structures date back to the early 13th century, but it was considered a chief sacred site far before then. The Inca people changed the large site into a very small but wonderful city, completely self-sufficient and hidden from below. Agricultural terraces (梯田) surrounded the entire city, fed by natural spring water, supporting the entire population.

Inca Trail

    The trail is one of the most famous in the world and regarded as one of the best. It covers only 26 miles, combining cloud forest, green mountain scenery, forest, and plenty of tunnels, paving stones, and ruins. The four-day hike begins slowly but quickly changes into a difficult journey suitable for those in excellent shape. The trail winds through the Andes, leading alongside and through ruins. Though independent hiking was once permitted, now it must be done with a guide.

Funerary Rock

    It is believed that the Funerary Rock at Machu Picchu was used as a place to prepare Inca nobles for preservation, or mummifying (做成木乃伊), a common habit among the tribe. Nobles would be laid out to be mummified by the hot sun and freezing cold nights after their organs were removed. The rock is also famous as a spot from which a view of the city is afforded.

Temple of the Sun

    Within the city's castle, deep within Machu Picchu, is the Temple of the Sun, accessed only by the Emperor and

    Inca priests. It means the Inca's advanced knowledge of religion, weather, and nature, showing the great extent

    Incas went to adapt to and learn about nature. Still unbroken, the temple was built to honor the god Inti, who is exactly the sun. The temple was effectively protected. It was also a very important scientific center, built in half-moon shape with openings facing north and east. The windows' shadows in the center of the temple helped see the start of winter solstice (至日), showing farming season.

    For years now, I've been wanting to sell our house, the place where my husband and I raised our children. But to me, this house is much more than just a building.

    In the front room, there's a wall that has hundreds of pencil lines, marking the progress of my children's growth. Every growth stage is marked in grey, with each child's name and the date when they were measured. Most people I know have been featured on a wall like this, or at least had a wall like it in their home.

    Of all the objects and memories, it is this thing in a home that is the hardest to leave behind. Friends I know have returned home after work only to discover their wall of heights has been freshly painted over. A new paint job wouldn't normally be greeted by tears, but erasing that evidence of motherhood hurts more than it should. Our children grow in so many ways, but the wall is the physical evidence of their progress, right there for everyone to see.

    Over the years, I've talked about how much I would hate leaving that wall behind when I moved, even though the last marks were made 10 years ago when my children stopped growing.

    So one day, while I was at work, my children decided to do something about it. They hired Jacquie Manning, a professional photographer. She came to our house, and over several hours, took photos of the hundreds of drawings and lines, little grey fingerprints and old marks. Somehow, she managed to photograph all those years of memories perfectly. Afterwards, she put all the photos together into one image, changing them into a beautiful history of my family.

    Three weeks later, my children's wonderful gift made its way to me — a life-size photo of the pencil lines and fingerprints that represents an entire lifetime of love and growth.

    Amsterdam, the capital and most populous city in the Netherlands, is one of the most popular travel destinations in the world, famous for its beautiful canals, top art museum, cycling culture, and Red Light District. Here are some of the key points to remember as you plan your trip to Amsterdam.

    Must-See Attractions

    Most visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You'll also want to check out Amsterdam's Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the Vondelpark. The top museums to visit are the Rijksmusuem, the Ann Frank House, and the Van Gogh Museum. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a popular place for celebrity spotting and nightlife today.

    Transportation

    Travelers should be aware that Amsterdam Airport Schiphol is one of the busiest airports in the world. This airport is located about 15 kilometers southwest of city center. You can catch a train from Schiphol to Amsterdam Central Station, which has many connecting routes. It's typically not a good idea to drive a car to the city center because traffic is heavy and parking is difficult to find. Cycling is incredibly popular here, and it's easy to find cheap bike rentals around town. Amsterdam has a flat terrain (地形) and is a great city to explore on foot.

    Money Saving Tips

    Unless you really want to see the tulips (郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.

    Look for accommodations in Amsterdam's South District, where rates are generally cheaper than in the city center.

    Buy train tickets at the machine instead of the counter to save a bit of money.

    Instead of hiring a tour guide, hop on a canal boat. They're inexpensive and will give you a unique point of view of the city.

Passing the Cities through the Lens (镜头) of Women, a solo exhibition by Swiss artist Catherine Gfeller, is being held at the Swiss embassy in Beijing.

Between 2016 and 2019, Swiss artist Catherine Gfeller embarked on a journey to a number of Chinese cities, weaving a narrative as she engaged with the stories of women from different backgrounds. Her vision of the women, the challenges they confront, and their distinctive spirit are the focuses of the artist's subsequent explorations.

In the bustling streets of Guangzhou, Guangdong province, Hong Kong, Beijing and Kunming in Yunnan province, Gfeller found a means of exploring the essence of these urban landscapes by focusing her lens on women. On Saturday, the Swiss embassy in Beijing launched a solo exhibition, Passing the Cities through the Lens of Women, which spotlights the perspectives and voices of women with photographs, texts, and videos. Through her lens, Gfeller skillfully establishes a dialogue and builds a bridge between the narratives of the women and the liveliness of the cities they inhabit. 

For Gfeller, women's voices are very important in modern Chinese society. During shooting, she learned how the women perceive the new ways of life and how they find an anchor in their cities. "The moment I pressed the shutter, I felt like I became part of the city," Gfeller says.

Ambassador of Switzerland to China Jurg Burri said at the opening ceremony, "Ms Gfeller cares very much about people, especially women in cities. Women's issues are a global topic and I hope that more women's voices will be heard."

The exhibition is open to the public until the end of March. The 58-year-old artist is known for her focus on landscape photography. Using techniques like montage, collage, and superimposition, she creates unique photographic artworks.
