1 . Mei Xiang, 25, Tian Tian, 26, and their 3-year-old son, Xiao Qi Ji, packed their bamboo and left for China on Wednesday, making D.C. panda-less for the first time in 23 years.
The trio’s departure followed months of goodbyes: a nine-day “Panda Palooza” celebration, final visits by generations of panda fans and one couple’s return to the scene of their 2016 engagement at the zoo’s panda house. And as with many breakups, the longer the relationship, the deeper the heartbreak.
Now all that’s left of those three bears are memories and mementos. Washington Post reporters gathered some of the items that symbolize the connection D.C.’s panda fans have felt to the animals for the past 51 years. They talked to some of the people who are deeply affected by the animals’ departure, and what they’re doing to stash their cherished memories away.
Soon after Yael Krigman moved her bakery, Baked by Yael, into a space across from the National Zoo’s entrance in 2015, people began to ask her for panda-related treats. Thus the panda cake pop was born. As time went on, the cake pops became a pillar (支柱) of her brand. Even with the pandas gone, Krigman said, the cake pops will remain.“The pandas are super cute, but their departure is not going to put us out of business,” she said.
Still, it’s possible fewer people will visit the zoo — and surrounding shops — after the pandas’ departure, said Robert Meins, executive director of Woodley Park Main Street.“You know, the more diverse and the more interesting the offerings that the zoo has, the more people will come — it’s that simple,” he said.
LiLLiES has been making “panda pancakes” since the restaurant opened in 2011, said Ryan Raihan, a manager there. When it opened, kids in panda hats and T-shirts would run in and order the pancakes.But splitting up with the pandas affects more than the restaurant’s brunch orders.“This hurts,” Raihan said. “They’re a huge part of our culture and our neighborhood. It’s not even about the financial gain or loss that is going to happen because of their leaving.”

2 . Anxious Animals
Our pets can get stressed by many things such as new places, changes in routine, new people, new additions like a baby or another pet to the home, and loud noises such as fireworks.
• Yawning
• Panting—with a curled tongue
• Pacing back and forth
• Licking their lips
• Ears pinned back
• Dilated pupils or red around eyes
• Whites of eyes showing (whale eye)
• Loss of appetite
• Backing away from someone
• Tail tucked between their legs
• Cowering (shrinking or crouching)
• Diarrhoea or more toileting
• Shivering (not cold or excited)
• Growling, flashing teeth, snapping or biting.
HOW TO HELP:
Give your pet time away
Avoiding or removing your dog from a stressful situation will help. Create a space away from children or a bed for them where they won’t get disturbed.
Exercise your dog
Stay nice and calm
Many dogs are very sensitive to their owner’s emotions and react to them. If your dog is stressed, keep calm and don’t panic or raise your voice as this might add to your pet’s stress levels.
This can help keep their mind focused and distracted from things they find stressful.

3 . Amsterdam, with its scenic canals lined with picturesque, 17th-and 18th-century buildings, a major European tourist destination, is slowly collapsing.
Sinkholes are appearing in small streets, and nearly half its 1,700 bridges are unstable and need repairs. The fundamental problem is the state of the canal walls: about 125 miles of them are so broken that they are in danger of collapsing into the canals, potentially taking buildings and people with them. As a huge project to shore up the canal walls gets underway, the city is beginning to look like one huge construction site.
Like much of the Netherlands, Amsterdam lies below sea level. Built on a swamp and heavily expanded in the 17th century, the city sits on millions of wooden piles that serve as foundations. As modern life changed the city, many houses were strengthened with concrete, but the foundations of streets and canal walls were ignored. Many of the wooden piles have shifted, cracked or collapsed under the pressure, causing bridges and can al side walls to sink and crack. Water then seeps in, washing away mortar(砂浆), further hollowing out the infrastructure and creating sinkholes.
The alderman, Mr. De Vries, said that if the city had continued to ignore the problem, it would have headed straight for a catastrophe. The reconstruction will take at least 20 years and will cost 2 billion euros, perhaps even more. “These are big numbers, and work needs to take place in a very busy, closely-populated area,” Mr. De Vries said. “People live here and work here, and we usually have many tourists.”
He acknowledged that Amsterdam in the coming years would look different from its usual postcard self. Still, he insisted that tourists should not be discouraged from visiting. “We invite everyone to come and see what we are doing,” he said. “We want visitors to realize that such a magnificent city needs maintenance.”

4 . In our human-centric view, the ability to shoot ink or change colors may seem odd, but you know what’s really odd? Menopause (更年期). You can count species other than humans known to experience and outlive menopause on one hand. Only Oracs (虎鲸) and some whale populations have females that live long past their reproductive years to become grandmothers. But a new, landmark study confirms that at least one population of chimpanzees can now be added to the list.
The discovery comes as the result of 21 years’ worth of observing the Ngogo community of wild chimpanzees in Kibale National Park, Uganda. Studying urine from 66 Ngogo females, aged 14 to 67, showed that their hormone levels changed after approaching 50, confirming they were in menopause. Interestingly, 50 is also the age when many people begin to experience menopause. “It’s really cool to finally have that piece of the puzzle come into place,” says Catherine Hobaiter, a primatologist who was not part of the new study.
But Catherine points out that the Ngogo community lives in a chimp paradise: the resource-rich, well-protected Kibale National Park that also lacks leopards, their main predator. And because the Noggo community is found in the heart of the park, its only neighbors are other chimps — not humans who can expose chimpanzees to viruses that have devastated other communities. “The Ngogo population may be an outlier (局外人) when it comes to the rest of the species,” she cautions.
And there is a question concerning “the grandmother effect”, according to which a grandmother has a decidedly beneficial effect on her children and grandchildren. Chimpanzees do not form long-term pair-bonds and females leave in search of new communities when they reach maturity, which means grandmother chimpanzees likely don’t know who their grandchildren are in the same way humans or even orcas do. What they do after the menopause remains a question of interest. “And that’s all future work to be done.” said Catherine.

5 . It’s a common belief that cats hate water. They don’t beg to play with water or jump in a pond or pool like dogs do. But what makes them hate one of the most plentiful substances on Earth? They have to drink it to survive, so what’s the big deal?
The easy answer is that they’re just not used to being wet. Cats clean themselves by licking (舔), so humans don’t usually bother to introduce them to bathing in water the way we do with dogs. Show cats, for example, to learn very early on to take baths and they don’t have that typical fear of water. If you want a cat that likes water, introduce it as a kitten to the idea that water is nice. Ideally, you start introducing them to water during their socialization period before they reach l6 weeks old.
The cat’s preference for bathing itself without any help from humans is another factor in its dislike of water. All that licking means cats have little oil buildup on their fur. Oil helps avoid water, so when cats do get wet, the water soaks all the way down to their skin. It makes their fur feel heavy and they can feel less quick and flexible.
We also use water for punishment. When they jump on the counter or lick our bowl of yogurt, or scratch (抓) the arm of the couch, we often spray (喷洒) them with water. It works because it’s an unpleasant surprise. It’s cold and uncomfortable, so they stop the behavior we don’t want them to do and run off to stare at us from a distance.
But not all cats hate all water. Big cats — like tigers — often even go for a dip. Even house cats like to drink from running water or play at the edge of a filled bathtub. They seem to enjoy the splashy noise and the sparkle of light on the water’s surface. Some breeds of pet cats even like to swim!

6 . A new study has found that light pollution is making the night sky brighter and the stars dimmer (暗淡的). The study examined data from more than 50, 000 citizen star watchers across the world, It found that man-made, or artificial lighting is making the night sky about 10 percent brighter each year. Data for the study was collected from 2011 to 2022.
The result was a much faster rate of change than scientists had estimated in the past. As cities expand and put up more lights, a “skyglow” is created in the sky. Skyglow is a term scientists use to describe light that becomes more intense. The research team gave an example to explain the result. If a child is born where 250 stars can be seen on a clear night, by the time that child turns 18, only 100 stars will be seen.
Past studies involving artificial lighting used satellite images of the Earth at night. They had estimated the yearly increase in sky brightness to be about 2 percent a year. But the satellites used are not able to identify light with wavelengths toward the blue end of the spectrum (光谱) — including light given off by energy-effective LED bulbs. The researchers noted that more than half the new outdoor lights put in across the United States during the past 10 years have been LED lights. The satellites are also better at finding light that gets spread upward like a spotlight than light that spreads out from side to side, Kyba said.
“Migratory songbirds normally use starlight to orient (确定方向) where they are in the sky at night,” said Georgetown University biologist Emily Williams. She was not part of the study. And when sea turtle babies hatch, they use light to orient toward the ocean — light pollution is a huge deal for them.
Falchi, the physicist at the University of Santiago de Compostela, said part of what is being lost is a universal human experience. “The night sky caused the generations before ours to have exciting new ideas or made them want to create something, especially in art, music, science and literature,” he added.

7 . A dinosaur footprint found by a four-year-old girl on a Welsh beach has been regarded as the “finest find in a decade” by experts.
Lily Wilder was walking her dog with her family at Bendricks Beach in Barry when she spotted the fossilized (石化的) footprint in the rocks. Her mother said that after making the find, she uploaded a picture to Facebook and was shocked to receive a “huge response” from fossil hunters. Mrs. Wilder then contacted National Museum Wales, who advised her to take down the post to avoid a wild rush of fossil fans towards the protected section of land.
The 110-mm footprint fossil has now been legally detached, after permission was given by the landowners and Natural Resources Wales, and is currently in safekeeping. The footprint fossil, believed to be around 220 million years old, will be taken to National Museum Wales, on a temporary or permanent basis.
Cindy Howells, who arranged for the legal removal of the footprint, said: “This is an amazing discovery. It’s the best-preserved footprint fossil that’s ever been found in South Wales-normally they’re hollow (中空的) or less well-defined, but on this one you can see the claws (爪子) and the points at the end. This discovery is unique and worth protecting — we will be studying the footprint and it will teach us a lot more about dinosaur feet and their bone and muscle structure.”
The footprint is believed to be that of a meat-eating dinosaur from the early days when dinosaurs were first starting to evolve (进化), around 10 million years after dinosaurs first emerged on Earth.
Lily, who now plans to get more dinosaur toys, will forever be named as the footprint fossil’s finder and will be invited into the museum once it reopens.

8 . One of the ocean’s noisiest creatures is smaller than you’d expect — snapping shrimp (鼓虾). They create a widespread background noise in the underwater environment, which helps them communicate, protect their homes and hunt for food. When enough shrimp snap (发出噼啪声) at once, the noise can be deafening.
Aran Mooney, a biologist at Woods Hole Oceanographic Institution, suggested that with increased ocean temperatures, snapping shrimp will snap more often and louder than before. This could raise the background noise of the global ocean. “They make a sound by closing a claw so fast. This makes a bubble (泡泡) and when that bubble bursts, it makes that snapping sound,” said Mooney.
Mooney discovered a strong relationship between warmer waters and more frequent snapping shrimp sounds after experimenting with the shrimp in tanks in the lab and by listening to the shrimp in the ocean at various water temperatures. “As the temperature rises, the snap rate increases,” he said. This makes sense because shrimp are essentially cold-blooded animals, meaning their body temperature and activity levels are largely controlled by their living environment. “We can actually show in the field that not only do snap rates increase, but the sound levels increase as well.”
How the louder snapping shrimp would affect or benefit the surroundings remained to be seen. “We know that fish use sound to communicate,” Mooney said. “If the environment gets noisy, it has the possibility to influence that communication. That’s something we have to follow up on.” There is also the possibility that the change of snapping shrimp affects machines humans use to discover mines, which could lead to unpleasant results.

9 . Antarctica (南极洲) is a great, icy land, surrounded by the huge Southern Ocean. The ice in Antarctica doesn’t just cover the land. There’s also a large area of sea ice, which floats (漂浮) on the ocean’s surface.
Scientists have been measuring the area of the sea ice in Antarctica since 1979. For most of this time, Antarctica has seemed to be almost not influenced by the changing weather conditions experienced in other parts of the planet. In fact, until recent years, Antartica’s sea ice area mainly set records for growing.
That began to change around 2016. Now, for several years, the area of Antartica’s sea ice has been getting smaller. This year, the US National Snow and Ice Data Center (NSIDC) reported that Antartica’s sea ice reached its maximum on September 10 — almost two weeks earlier than normal. And the sea ice was at a new record low — not just by a little bit, but by a lot.
The last time Antartica’s low sea ice set a record at the end of winter was in 1986. And this year, there’s about 1.03 million square kilometers less sea ice than in 1986. It’s hard to picture such a large area, but it’s around 1.6 times the size of France.
Scientists are still trying to understand what is driving the change in Antarctica. Ted Scambos, a research scientist at the University of Colorado, says, “Antarctica’s ice levels have always changed some, but the situation this year is pointing towards warmer ocean conditions around the area.”
The new low record has scientists worried. The sea ice is important, because it helps cool the planet. When it’s frozen, sea ice reflects sunlight back out into space. But when the sea ice melts (融化), the water left behind is darker, and takes in and keeps more heat.
1. What did NSIDC find about the sea ice in Antarctica this year?| A．It protected the wildlife in the ocean. | B．It grew and covered a wider area. |
| C．It turned out to be difficult to observe. | D．It reached a new record low level. |
| A．To present the total area of the country. |

| C．To show the sharp loss of Antarctica’s sea ice. |
| D．To explain the position of the wonderful land. |
| A．Low rainfall. | B．Rising temperatures. |
| C．Cold weather. | D．Short summer months. |
| A．It’s key to the earth’s cooling system. | B．It’s just a short-term problem. |
| C．It reminds us to find water resources. | D．It offers humans a bright future. |
