1 . A new study on 26 chimpanzees (黑猩猩) from zoos around the world found that chimpanzees can recognise family members and long lost friends even after decades of separation.
The participating chimpanzees were given juice while staring at a screen flashing side by side photos of other chimps. One animal from each pair of photos had lived with the group for at least a year, while the other was a stranger. An eye-tracking camera recorded where the participants were looking and for how long. Data showed their eyes rested longer on familiar groupmates, suggesting “rich recognition of each other.”
There is also evidence that they became more intent when shown a picture of a chimpanzee with whom they’d had more positive interactions, compared with conflicting relationships.
In the most impressive case, a 46-year-old chimpanzee named Louise repeatedly demonstrated “intense” attention upon seeing photographs of her sister Loretta and nephew Erin, whom she hadn’t seen in more than 26 years. The team said Louise’s results represent the longest-lasting social memory documented in any non-human animal to date.
“We tend to see ourselves as unique special creatures with incredible intellectual (智力的) capacities that are very different from other animals on earth,” said Laura Simone Lewis, a postdoctoral fellow in Berkeley’s psychology department and lead author of the study. “This study is showing us how similar we are to chimpanzees.” She noted that the findings support the theory that long-term social memory in humans and modern day chimps has come from “our last common ancestor that lived somewhere between 5 to 7 million years ago” who also likely had long-term social memory.
Now that they have definitive evidence that these endangered species possess long-term social memories, researchers have more questions, including whether chimpanzees miss the individuals they’re no longer with, especially their friends and family. “Our study doesn’t determine they are doing this, but it raises questions about the possibility that they may have the ability to do so,” Lewis said.

I have a passion for fishing and animal protection, which can date back to my childhood. When I was young, my father was a fish and wildlife officer, so he traveled all over the province in the spring and fall. He loved his job, especially the part where he protected nature from human.
He’d taught me to fish alone, in silence, lost in my own thoughts.
I still remembered that special day. Midweek, even in late August, no one was around. Police Outpost Lake is as far as you can go and still be in Canada. Songbirds, ducks, and Canada geese glided (滑翔) by on the breeze, touching down briefly on the water’s surface before flapping and quacking their way back up into the sky, passing in front of the sun, temporarily blocking its warming rays.
“How can I get the fish with these birds making noise?” I complained, rod (鱼竿) in my hand.
“Be patient, Jacob. Birds won’t disturb you.”
Out of the corner of my eyes, I suddenly caught a glimpse of a few great northern loons (潜鸟) stayed together not far from the shoreline. Dad once told me loon usually travel alone, but here were five of them in a group. Maybe it was a family? One loon, making odd sounds, swam away from the group, towards me.
This is unusual.
“Dad! Come here! Take a look at this loon!”
Hearing this, dad laid his rod down on the dirty sand, walking quickly towards me.
The loon rested in the shallow water near shore, not ten feet away from us. It was so close, we could see its red eyes.
“Look at that beak (喙)!”I said. “It could easily hurt us to death with that thing! It could tear our faces! Blind our eyes!”
Walking into the water, getting closer to the loon, we both saw thin wire wrapped around its neck. Fishing line maybe? Was there a hook(钩子)on the line, too? Was the loon asking us for help?

3 . As AI becomes popular, researchers have noticed its influence on the environment. Training an AI system requires huge computing power and electricity, and the resulting CO2 emissions (排放) are one way AI affects the environment. But its environmental effect is more than its carbon (碳)footprint.
Jesse Dodge, a scientist at the Allen Institute, says, "The influence of Al systems is going to be from their applications, not the cost of training them." David Rolnick, a computer scientist at McGill University, compares AI to a hammer (锤子) “The main effect of a hammer is what is being hammered,” he says, "not what is in the hammer." Just like a hammer which can either destroy things or build a house, Al can hurt or help the environment.
In 2019, ExxonMobil, an oil company, said it would use Microsoft’s app Azure. With the Al technology, it would increase its production and create billions of dollars. This means Microsoft's AI is directly contributing to greenhouse gas emissions. This is not the only AI application that could be environmentally harmful. AI behind the ads that jump out on Instagram or Facebook pages pushes customers to spend more on products like clothes. This in turn causes more emissions through more production and delivery.
But on the other side of the coin, there are AI applications that can help deal with environmental problems, such as the destruction caused by hurricanes. One such application is xView2, a program started by a U. S. organization. It can recognize buildings damaged and people trapped in natural disasters, reducing danger and saving time for rescuers.
AI could be a valuable tool in the fight against climate change—if the Al industry can reduce its harmful climate effects. "Both AI and climate rules have roles to play." Rolnick says. When creating Al rules, he suggests considering its applications, emissions, and other production costs. Further, Dodge adds that those AI professionals should help set up some value systems to limit the technology's use.

One day two years ago, my mother came home from work and announced that she had found a pet for the family. My father, little sister, and I eyed her in doubt.
My sister asked what kind of dog it was. My mother said it was a poodle (贵宾犬) named Pepe. I couldn’t believe she wanted a poodle — especially one with such an ordinary name. But she had made up her mind. “Actually, I’m doing a co-worker a favor,” she said. “The woman who owns Pepe says he hates to be alone and needs children to play with him.”
Pepe arrived the next night. His short tail shook happily. I didn’t get very close to him, thinking he should have stayed with his previous owner. My little sister played with him until bedtime, and he would come to me and begged for more attention. I always ignored him. But no matter how I treated him, he’d always like to be with me. He has always been waiting for me at the front door at the end of the day, smiling happily. He seems to know that I will be coming home from school at that time. Every day, he asks me with his eyes to play with him or take him somewhere. At night, he will wait until I fall asleep, leave his bed by the wall heater, walk down the hall and jump onto the end of my bed.
One night, while everyone was sleeping, I was in a half dream state. My throat hurt, my eyes pained, and some animal was crying in my ear. I opened my eyes and saw fog in my room. I wondered who left the window open. Pepe cried and bit my pajama sleeve (睡衣袖). Then I woke up and realized that it wasn’t fog in my room — it was smoke.

5 . Butterflies are the adult stage of an insect belonging to a group called Lepidoptera, which is a Greek word meaning “scaly wings.” The term is appropriate, as the wings of these insects have thousands of overlapping (重叠的) tiny scales. They give the butterfly its super appearance as the scales are set in colorful patterns unique to their species.Butterflies have the typical body of insects: head, thorax, abdomen, and six legs. They also have an exoskeleton (外骨骼) and two feelers.
The first stage of butterfly life is the egg. These shells are tiny and can be roundor oval. Females attach eggs to plant stems or leaves, which serve as food when the larvae (幼虫) hatch.
At the second stage, the larva/caterpillar hatches. The new animal may have a number of legs. Several pairs will be true legs but some will be false legs. The caterpillar has a greedy appetite and spends most of its life eating. It grows a lot during this phase, only the outer skin doesn’t grow along with the rest of its body. Outgrowing its skin, the caterpillar molts, ridding one exoskeleton and replacing it with another. Caterpillars may go through up to five molts.
The third stage is the chrysalis (虫茧). Caterpillars find a spray and make it home. (They may use a wall or other support.) The exoskeleton splits and reveals the chrysalis. The chrysalis shell hangs like a big bag. Inside the shell, the caterpillar breaks down. It rearranges its structure, growing a new body, legs, and wings. Unlike the caterpillar, the chrysalis doesn’t eat. It survives on energy from food eaten during the larval stage. This third step can last from several days to twelve months.
The final stage is the birth of the adult butterfly. The chrysalis splits, and the butterfly emerges.
Most adult butterflies live a week or two. Some species live as long as 18 months.

6 . Dogs may have earned the title of our best friends through their interactions with humans, but now researchers say these social skills could, be present shortly after birth rather than being learned.
To better understand the role of biology in dogs’ abilities to communicate with humans, the researchers studied 375 eight-week-old service dogs. They looked at how these dogs performed in a series of tasks designed to measure their communication skills. The puppies were still living with their littermates (同窝出生者) and had not been sent to live with a volunteer puppy raiser, making it unlikely that they had learned about his or her behavior.
In the first task, a person hid a treat beneath one of two overturned cups and pointed to it to see if the puppy could follow the gesture. Since dogs are good at using noses to find things a treat was also taped to the insides of, both cups. In the second task, puppies watched as the researchers placed a yellow, block next to the correct cup, instead of pointing to indicate where the puppy should look for the food.
The third task was designed to observe puppies’ tendency to look at human faces. The researchers spoke to the puppy in a voice people sometimes use when talking to a baby. They then measured how long the puppy fixed a stare on the human.
In the last task, researchers sealed a treat inside a closed container and presented it to the puppy. They then measured how often the puppy looked to the human for help in opening the container.
The study found that while many of the puppies were responsive to humans’ physical and verbal cues, very few looked to humans for help with the unsolvable task. Researchers said, “This suggests that while puppies may be born knowing how to respond to human-initiated communication, the ability to initiate communication on their own may come later.” The next step will be to see if specific genes that may contribute to dogs’ abilities to communicate with humans can be identified.
1. Why were eight-week-old service dogs chosen for the study?| A．They were the best age to learn. |

7 . Dog ownership may be associated with longer life, especially for heart attack and stroke (中风) suvivors who live alone, according to a new study.
Previous studies have shown that dog ownership alleviates social isolation (隔绝), improve physical activity and social bonds, even lowers blood pressure, leading researchers to believe dog owners could potentially have better health outcomes compared to non-owners. They sought to determine how dog ownership affected health outcomes.
Researchers compared the health outcomes of dog owners and non-owners after a heart attack or stroke using health data provided by the Swedish National Patient Register. Patients in the study were Swedish residents aged 40 to 85 who experienced a heart attack or stroke. Compared to people who did not own a dog, researchers found that for dog owners, the risk of death for heart attack patients living alone after hospitalization (住院) was 33% lower and 15% lower for those living with a partner or child. The risk of death for stroke patients living alone after hospitalization was 27% lower and 12% lower for those living with a partner or child.
The lower risk of death associated with dog ownership could be explained by an increase in physical activity and decreased depression and loneliness, both of which have been connected to dog ownership in previous studies.
While this study drew the conclusion from a large sample (样本), potential misclassifications (错误分类) of dog ownershipin couples living together, death of a dog and change of ownership could have affected the outcomes of the study.
The results of this study suggest positive effects of dog ownership for patients who have experienced a heart attack or stroke. However, more research is needed to confirm a cause-effect relationship. Moreover, from an animal welfare perspective (角度), dogs should only be owned by people who feel they have the ability and knowledge to give the pet a good life.

8 . Once again, China has conquered the world’s highest peak, Mount Qomolangma, on May 4th, 2022. Thirteen members of the Chinese Earth Summit Mission 2022 scientific expedition (探险) team successfully established an automatic weather station at an altitude of over 8800 meters, the world’s highest of its kind, on Mount Qomolangma on the China-Nepal border, achieving the milestone task of the country’s second comprehensive survey to the roof of the world.
To finish this mission, Yao Tandong, a leader of the expedition, said they have organized a massive party consisting of 16 teams and over 270 researchers, some of whom trained for over two years for the project. Now they have set up eight stations from 5200 meters to 8800 meters on Mount Qomolangma, with four stations higher than 7000 meters respectively at 7028 meters, 7790 meters, 8300 meters and 8800 meters. These weather stations at different altitudes mainly monitor the temperature, relative humidity, wind direction, wind speed, pressure and radiation changes in the region, and can realize real-time remote transmission (传输) of data.
Conventional weather observations are generally below 5000 meters and rarely above 5000 meters, and such high-altitude weather observations are scarce at the moment, Zhao Huabiao, a researcher at the Institute of Tibetan Plateau Research, said. “The reason for building a weather station at 8800 meters instead of 8848 meters is that the snow and ice on the summit are not suitable for fixing equipment, and in this regard, the weather station was built on bedrock around 8800 meters which is easier,” said Zhao.
The team reached the summit of Mount Qomolangma and used high-accuracy radar to measure the thickness of ice and snow, and collected samples for further research. Kang Shichang, a researcher of the Northwest Institute of Eco-Environment and Resources under the Chinese Academy of Sciences, said studying the changes to the glacier aims to clarify the impact of global warming, which is beneficial to mounting a global response to climate change. “Through the study of glacier changes and glacier air pollutants, we can see the impact of global and regional human activities in the Qomolangma area,” Kang said.

9 . “Flying insects don’t fly directly to lights from far away because they’re attracted to them, but appear to change course toward a light if they happen to be passing by due to a strange inborn biological response,” writes Samuel Fabian, a bioengineer, in a research paper.
Until now, the leading scientific hypothesis has been that insects use the moon’s light to direct the way at night and mistake artificial lights for the moon. But this idea doesn’t explain why insects that only fly during the day also gather around lights.
To find out what really happens, Samuel’s team track the precise movements of insects in the wild around lights using a high-speed camera. This revealed two notable behaviours. First, when insects fly above lights, they often invert (转向) themselves and try to fly upside down, causing them to fall very fast. Just after insects pass under a light, they start doing a ring road. As their climb angle becomes too steep, they suddenly stop and start to fall. Second, when insects approach a light from the side, they may circle or “orbit” the light.
The videos show that the inversions sometimes result in insects falling on lights. It can appear to the naked eye as though they are flying at the lights. “Instead, insects turn their dorsum toward the light, generating flight perpendicular(垂直) to the source,” the team write. It is common to the two behaviours that the insects are keeping their backs to the light, known as the dorsal light response (DLR). This DLR is a shortcut for insects to work out which way is up and keep their bodies upright, as the moon or sun is usually more or less directly above them, and this direction allows them to maintain proper flight attitude and control. They also find that the insects fly at right angles to a light source, leading to orbiting and unstable flights as the light’s location relative to them changes as they move.
Samuel’s team suggest that a possible outcome of the research could help the construction industry to avoid the types of light that most attract insects.
