1 . Imagine walking into the depths of the jungle (丛林) to observe the chimpanzees who cal it home. With a click of your camera, you document groundbreaking information about the species. Sounds wonderful, right? Jane Goodall did just that.
When Goodall was young, reading and exploring nature were her ideas of fun. Her mother encouraged her to learn and ask questions. Goodal dreamed of seeing the habitats (栖息地) of her favorite animals like chimpanzees firsthand.
In July 1957, when she was 23, Goodal arrived in Tanzania, East Africa, and journeyed to the Gombe Stream Chimpanzee Reserve. She learned early on that studying chimpanzees wouldn’t be easy. To observe chimpanzees up close, she had to gain their trust. That took months. To her, the chimpanzees were complex creatures with lives surprisingly similar to ours.
In October 1960, Goodall was observing chimps. She watched as they made tools out of grass stems to pick ants out of a nest. Until then, people thought humans were the only species that used tools, Because of Goodall’s discovery, chimpanzees are now accepted as intelligent, social animals.
Goodall established the Jane Goodall Institute in 1977, to provide conservation and environmental education. In the late 1980s, her focus shifted to something much larger. Deforestation (滥伐森林) and climate change were affecting the world’s natural habitats. The vegetation chimpanzees depended on for food was in danger. Goodall left Gombe to help. The fight she began against habitat loss continues today, through animal reserves and research sites.
Throughout her life, Goodall’s work has protected the lives of people and animals around the world. And she encourages young people to join in this fight for a better world. In 1991, she founded Roots & Shoots. It equips young people to take action on issues that matter. Goodall says that if we all do our part to help, the world will be a better place.

2 . A new study, published in the journal Sleep Health, has suggested that taking a short nap (小睡)during the day may help to protect the brain’s health as it ages, after finding the practice appears to be related to larger brain volume (容量).
While previous research has suggested long naps could be an early sign of Alzheimer’s disease, other research has showed that a brief nap can improve people’s ability to learn. Now researchers say they have found evidence to suggest that napping may help to protect against brain’s dwindling, a process that occurs with age and is faster in people with cognitive (认知的)issues and neurodegenerative (神经变性的)diseases.
Researchers at University College London(UCL)and the University of the Republic in Uruguay drew on data from the UK Biobank study that had collected lifestyle and health information from 500,000 people aged 40 to 69. “Overall, we found a connection between habitual daytime napping and larger total brain volume equal in 2.6 to 6.5 fewer years of ageing, which could suggest that napping regularly provides some protection against neurodege neration through making up for poor sleep,“ said Dr Victoria Garfield, a co-author of the study from UCL.” A short daytime nap could help preserve brain volume and that’s a positive thing, potentially for dementia prevention,” said Garfield, adding that previous research suggested a period of up to 30 minutes may be beneficial.
But the study is based on data only from European, and the exact period of naps connected with the benefits are unclear. Tara Spires-Jones, the president of the British Neuroscience Association welcomed the study, although she said it had limitations including that the self-reported napping habits of the UK Biobank people who took part may not be entirely accurate. “This study is important because it adds to the data indicating sleep is important for brain health,” she said.

3 . When Arvin Kuipers, who graduated from Beijing University of Chinese Medicine in 2017 and loves Chinese culture, asks his patients to stick out their tongue so he can diagnose(诊断) their illness, many are confused.
Kuipers, 30, practicing Traditional Chinese Medicine (TCM) in Amsterdam in the Netherlands, said, “In TCM I need to do face and tongue diagnosis. That’s strange for people in my country.” One elderly woman had been visiting him occasionally for advice, but her first experience with TCM surprised her. She had never experienced acupuncture (针灸) or any other TCM treatment. “She came in, and I examined her face and tongue,” said Kuipers. “I told the patient her kidneys were not doing well and that she wasn’t getting proper sleep.” The woman was shocked by his insight and asked if he had been spying on her. “Actually, it was easy to diagnose her condition when I saw the dark rings under her eyes. Her energy levels were also very low at the time.”
Kuipers opened his TCM clinic in September. Most of his work involves performing acupuncture, cupping as well as tuina — a TCM massage that patients in the West like the most, he said. In some cases he also gave his patients traditional herbal medicines.
Kuipers usually makes a cup of Chinese tea to calm his patients if they are nervous about the acupuncture needles. He also explains to them the meridian (经络) system, which is a central concept of TCM, yin and yang, and other concepts. “In TCM, good health requires balanced yin and yang, so practitioners not only pay attention to a patient’s illness, but also to his or her overall physical condition,” said Kuipers. “TCM is also a different culture and offers a new perspective, instead of being a curing method.”
As of early April, Kuipers has treated more than 200 patients, many of whom come to his clinic every week. “TCM does work, and works well. My patients really feel better with it, so I value it, and when my patients feel better I also feel better.”

4 . Wandering in a thick forest amid fresh air, colorful flowers and the sweet melodies of wild birds, tourists might feel they are in a fairy tale world. In fact, they are picking wild mushrooms in Yunnan Province. Known for its breathing-taking landscapes and diverse ecosystems, Yunnan provides a lot of mushroom picking destinations.
Xu Yaowei is in charge of a mushroom picking project on the app “Youyunnan”. He explained to China Daily that it was launched in early July. There are two types of tour routes. The first mainly aims at tourists from outside the province. Their main demand is for a mushroom hunting experience, focusing on easily finding mushrooms. The second route is for local and high-end customers, and includes a mushroom hunting experience, picking wild tea, enjoying a mushroom feast on a farm, and visiting a local wild mushroom market.
The project is already a success. By the end of August, it conducted nearly 40 one-day wild mushroom collection tours, serving nearly 800 tourists. More than 95 percent of them are from outside the province. Most of them are college graduates and parents with children, ranging from 25 to 35 years old.
One tourist surnamed Li said, “The most unforgettable was undoubtedly our encounter (遇到) with the professional and passionate tour guides.” “Their attractive stories and interactive sessions deepened our understanding and appreciation of the wild mushrooms we encountered,” Li added.

5 . Goldfish may seem like simple creatures swimming in a glass tank, but they possess a rather complicated navigation system, as discovered by researchers at the University of Oxford Led by Dr. Adelaide Sibeaux, the study aims to shed light on our understanding of how fish, and potentially humans, estimate distances using what could be described as an internal GPS.
Writing in the journal Proceedings of the Royal Society B, Sibeaux and colleagues report how they created a tank in their experiment with 2cm-wide black and white vertical stripes (条纹) on the walls, connected by similar stripes across the floor. The team trained nine goldfish to swim a set distance of 70cm and then return to their starting point when waved at. The experiment aimed to investigate how the fish would estimate this distance without any gestures, under different patterns.
Over multiple trials, the goldfish averaged a swim distance of 74cm, give or take 17cm, when presented with the vertical 2cm-wide stripes. However, when the stripe pattern was altered to either narrower vertical stripes, checked patterns, or horizontal stripes, the fish’s behavior changed significantly. Narrower vertical stripes led them to overestimating the distance by 36%, while horizontal stripes resulted in highly inconsistent estimations.
According to the researchers, the goldfish appeared to be using an “optic (光学的) flow mechanism” based on the visual density of their environment. They kept track of how frequently the vertical pattern switched between black and white to estimate how far they had traveled. The study suggests that different optic flow mechanisms are used by mammals, including humans, based on angular (有角度的) motion of visual features. The study implies that the use of visually based distance information could have emerged early in the evolutionary timeline.
“This study is novel because, despite knowing that fish respond to geometric information regarding direction and distance, we don’t know how they estimate distances,” Professor Colin Lever, although not involved in the study, said, “it’s exciting to explore fish spatial mapping because fish navigation evolved earlier and better than most mammals.”

8 . When the sun goes down in the evening and you are sitting outside at home, you may not be able to see many flowers in the yard without artificial lighting.
The plants with silver or multi-colored leaves, white or light-colored flowers, or flowers that open only at night are good choices for a moon garden. Another way to enjoy plants in the evening is to choose ones with a pleasing smell. Plant them along a walkway or near a seating area outdoors, where you can enjoy them up close, or within view of a window.
Select plants depending on season or temperatureYou can begin the garden early with early bloomers, like lily of the valley. Make the season last longer into the autumn with late bloomers like chrysanthemum. In very warm places, try planting frangipani to fill your evenings with pleasure.
For the best visual effect, plant in groups of three, five or seven of the same kind of plant. That is a good gardening method in general because it avoids creating a disorganized mixture of plants and flowers. But it is more important in a moon garden.
There is one more thing to increase how much you can see your moon garden—add some small lights that face the plants.
A.Insects that visit flowers at night love them |
B.Plant some plants that show well in moonlight |
C.They will increase the appeal of your moon garden |
D.However, with some planning, you can have a moon garden |
E.You certainly don’t want your single plants to get lost in the dark |
F.Find the plants that work best in your climate by talking with a local expert |
G.These plants can be seen after sunset and especially shine under a full moon |
