7 . In an effort to help out important insects like bees and butterflies, bus stops across the United Kingdom (UK) are getting living roofs. Small gardens on bus shelter roofs are being planted with flowers chosen to help support the struggling insects. The gardens provide much-needed islands of nature in a man-made environment of a city.
Humans count on bees and other “pollinators (授粉者)” like butterflies to help grow plants, such as flowers and trees. But with humans taking over more and more land for cities, roads and farms, more natural areas have disappeared. The Wildlife Trusts, a group which works to protect wildlife in the UK, says that 97% of England’s wildflower fields have been lost since World War II and the insect numbers there have dropped by 50% since 1970. Bee bus stops are a small step toward supporting these important insects.
The advertising company Clear Channel is working with The Wildlife Trusts and city governments to set up bee bus stops in cities across the UK. Bee bus stops are like ordinary bus shelters, but small gardens have been added to the roofs. The gardens are filled with flowers and plants chosen to attract bees and butterflies. The company plans to set up 1,000 bee bus stops in the UK.
Clear Channel already has bee bus stop programs in several countries in Europe. In the Netherlands, the city of Utrecht has 300 bee bus stops. Research shows that these bus stops—along with many other steps taken to support pollinators—may be helping. After decades of dropping numbers, bee populations in the Netherlands seem to have become more stable over the last few years.
The little gardens can also help to slightly lower city temperatures. Even though the bus shelter gardens are small, together they add up to a much larger area. Thirzah McSherry, who works for The Wildlife Trusts, says, “We’re living through a nature and climate crisis and we need to use every tool we’ve got to deal with it.”

8 . Like other penguins, African penguins have white feathers covering their chests and black feathers covering their backs. They have lifelong mates, and they live in huge numbers —so, scientists wondered how the birds were able to identify their partners among a sea of black-and-white birds. To find it out, they studied 12 African penguins at a marine park called Zoomarine Italia.
In one test, they hung two life-size photographs of the African penguins. One is selected randomly(随机选择地), while the other is the test subject’s mate. The scientists recorded their interactions with the photos: How long did they spend looking at each photo, as well as how much time did they spend standing near each one? The penguins spent more time looking at the photo of their partners—about 23 seconds longer, on average —than looking at the other photo. They also stood next to the mate’s photo for twice as long. Then, the researchers covered up the heads of the birds in the photographs, and the penguins still stayed near their partners’ photos.
In another experiment, the researchers hung up two photos of a bird’s mate —but, in one, they had digitally removed its spots(点). In this case, the penguin again spent more time looking at the photo with the spots. In the third experiment, the researchers hung two penguin photos with digitally removed spots—one of the test subject’s mate and the other: a random penguin. In this case, the penguins did not appear to recognize their partners—they spent almost the same time looking at or standing near both photos.
Together, the research results suggest African penguins are zeroing in on their partners’ spots and using them like name tags. Scientists say: “Our results prove birds recognize their mates by specific visual patterns and all sensory modalities(模态)should be considered in the study of animal communication.”

10 . Four Natural Wonders
Poás Volcano, Costa Rica
Sitting more than 2,707 metres above sea level, Poás Volcano has been active for hundreds of years. Visitors can still get up close and personal with it at the national park where it’s located (with a reservation).
Tips: Dress warm and bring an umbrella, as rainfall is common at the top of the mountain due to unpredictable weather conditions.
Mount Otemanu, Bora Bora
Mount Otemanu is the main attraction on Bora Bora, an island first made popular during World War I. The massive mountain, which stands 727 metres above the lagoon of Bora Bora, is now the perfect backdrop for dreamy Tahitian sunsets. A few of the luxury resorts on the island which offer great views of the mountain have become hot spots for honeymooners.
Grand Canyon, USA
Arizona has no shortage of impressive mountains and sweeping views, but the Grand Canyon is hands down one of the most diverse geological wonders in the state. Visitors have several options to experience the beauty here: adventure seekers can enjoy an aerial view from a helicopter ride through the canyons or go whitewater rafting down the Colourado River.
Cappadocia, Turkey
You may have seen fascinating photos of colourful hot air balloons against a magical landscape of rugged cliffs, valleys and towers carved into the rocks. It’s hard to believe this place is real but it is and it’s in Cappadocia! For a good position overlooking the landscape of this natural wonder, check out Uchisar Castle or ride during sunrise in a hot air balloon.
