There was a time when my favorite thing to do in the entire world was to play in the woods near our house. A river ran through them, so not only could I climb branches, but I could turn over rocks on the riverbank and find baby eels (鳗鱼).
My favorite book was called Guide to Reptiles (爬行动物). My father had given it to me for my birthday, and I read every page over and over, looking at the pictures of colorful animals. Some of the snakes were the most beautiful creatures I had ever seen, and some were described as poisonous, but still an important part of the ecosystem.
Little did I know that my book would end up saving a life.
My family moved to Virginia, into a new house. The houses were so new that no one had lived in them before. In fact, woods had been there first, and almost all the trees had been cut down to make room for houses and driveways. Inside our new house, everything smelled like fresh paint. Outside, no lawns had been planted, but my father tossed out grass seed and baby seedlings grew. My brother Patrick and I could not walk on them. We had to play in the driveway.
All the same, I liked our new house. One of the best things about living near the woods were the animals that would come into our yard. Rabbits and turtles came over every night. It seemed as if they were only trying to go home, and instead, what they had found was a big new land where their old homes used to be.
Besides playing in the driveway, we spent time in a sandbox, which my father built right next to the driveway. One day before dinner, I ran to the sandbox to build a castle but found there in the sandbox was a snake.
It was lying very still, and it was beautiful. The snake had rings of color around it-red, then white, then yellow, then black. I had seen a picture just like it in my reptile book, and I remembered that it was one of the prettiest snakes in it. It said in the book that the poisonous snake looked very much like it. I was scared and ran inside.
Para 1: “Dad! Dad! There’s a snake in the sandbox!” I yelled.

2 . Heat waves are becoming more common in parts of the United States — and that means more people running their air conditioners for longer. But those air conditioners can make the problem worse, giving off greenhouse gases as they work that contribute heavily to climate change.
SkyCool Systems is trying to break that cycle, using technology that promises to offer buildings an alternative means to cool down in a similar way to how the planet cools itself. “Our planet naturally cools itself by sending heat out in the form of infrared light (红外线) or radiation,” said Eli Goldstein, SkyCool’s cofounder and CEO. “We do this through rooftop panels, which look like solar panels but actually do the opposite, reflecting 97% of the sunlight that hits them and cooling the surface below,” said Goldstein.
SkyCool’s model involves fixing a network of pipes below those panels. These pipes are filled with water, which is kept cool by the panels and then flows into an air conditioning system. This process is designed to take pressure off the system’s cooling mechanism. And because the panels cool naturally and don’t need external power to function, it helps the entire system use less electricity.
A Grocery Outlet store in California, which has been using SkyCool’s system since last year, says it saw a marked drop in its electrical bills. Jesus Valenzuela, the store manager, estimates that the panels have saved his store roughly $3,000 a month.
But perhaps the biggest barrier to making the technology ubiquitous (无处不在的) is its relatively high cost. Increasing production could help bring the cost down, Goldstein said, particularly for developing countries in Asia and Africa where SkyCool hopes to eventually expand. For now, the company is focused on commercial applications of the technology, though it hopes to start setting up panels on the roofs of individual homes. “We’re just excited to be able to use this new technology for good,” Goldstein said.

3 . In gardens across Britain the grass has stopped growing, which is not drought-stricken. In fact, it is greener and cleaner than ever before. That is because the lawns (草坪) are actually artificial substitutes.
Britons are fascinated by lawns. Country estates (庄园) have long competed to have the most perfectly cut and polished grassland. “What you’re saying in big loud capital letters, is ‘I’m so terribly wealthy’,” says Fiona Davison of the RHS (皇家园林协会). With the coming of grass-cutting machines in 1830, the middle classes joined the fun.
But now Britons have fallen in love with artificial grass. Evergreens UK, which sells the stuff, says it has seen a 120% rise in sales since 2015. Artificial grass is popular with families who have children or dogs and don’t want mud dragged through their houses. It has another charm factor, too — people now see gardens as “outside rooms” — pairing carpets of artificial grass with delicately decorated seating and hot containers.
Not everyone is a fan. Artificial grass contains microplastics that ruin soil and risk flooding. A study finds earthworms gain 14% less body weight when operating under rubber, a form of artificial grass, which might not be a problem for its fans, as wormholes are regular disgusting things, but it disappoints green types. Ms Davison says a group of wildlife-loving gardeners is blooming, many having caught the bug during COVID-19 lockdowns. For example, a landscape designer says they like things less neat and try “to capture that wild element”. These eco-gardeners are influenced by rewilding projects and are more likely to be environmentalists.
While three written documents signed by many people have tried to stop artificial grass spreading, the government says regulating what people do in their backyards is wrong. The RHS is concerned about artificial grass, but prefers persuasion to laws. “We say ‘Let a hundred flowers bloom’,” says Ms Davison.

5 . Lay eggs and make noises — that’s it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters (公鸡) could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental contexts.
Whether animals can recognize themselves and thus have self-awareness is one of the central questions in behavioral research. The mark test, a classic test for self-recognition came to the scientists. In the test, if an animal stands in front of a mirror and begins to explore the colored mark placed on its body, this is considered proof that it recognizes its reflection as itself.
“However, our goal was to conduct the mirror test in an environment that is better adapted to the ecologically relevant behavior of the roosters,” says Sonja, a researcher from the University of Bonn. She came up with the idea of using a natural behavior of roosters for the experiment.
Initially, the researchers set up a test area and placed a net to separate two compartments (隔间), through which the roosters could see each other. Then a picture of a fox was placed onto the ceiling of one compartment. Faced with the predator, the roosters let out 77 alarm calls in the presence of a partner, but only 17 when they were alone. The result shows that most roosters, faced with a fox, do alarm partners, which is the perfect illustration of the animals’ self-awareness. The next step was to place a mirror between the two compartments instead of the net. In all, only 25 alarm calls were let out. “The result indicates that the roosters don’t mistake their reflection for a partner, and possibly recognize themselves in their mirror image,” says Sonja.
For comparison, the team also performed the classic mark test. Here, the roosters didn’t recognize themselves in the mirror. The research team sees clear evidence that the classic mirror-mark test produces more reliable results when the behavior of the particular species is included in an ecologically relevant context. “In the classic situation, a rooster may not show self-recognition,” says Sonja. “But when a fox threatens him, it becomes clear that his reflection is not another rooster, but himself.” Further research on animals’ self-awareness is needed so as to better understand animal rights and animal welfare.

6 . This year marks the 20th anniversary of China’s first manned space mission, with Yang Liwei becoming the first Chinese astronaut to go to space. Since then, another 19 astronauts have reached for the stars. The selection of the fourth generation of astronauts began in 2022 and is now in full swing. Experts revealed how tough the training is before astronauts can fly to space.
The human body is not designed for space life. Astronauts are faced with multiple challenges on a space mission. The changes in gravity can have an impact on their bodies. The sensation of confinement(封闭)living in a small spacecraft for months can damage their mental health. Emergencies during missions challenge their knowledge and ability to solve problems under huge pressure. So it’s no wonder that astronauts have to meet extremely high standards and go through a tough training program.
To make sure that Chinese astronauts complete their missions and return to Earth safely, “Eight types, including over 200 subjects of training, were set,” Huang Weifen, chief designer of the astronaut system for China’s manned space project, told CCTV News. Apart from physical fitness training, it also includes basic scientific theories, psychological health, and mock(模拟)missions.
Among the training subjects, the most tiring one is underwater training. This training is designed for astronauts to adapt to the microgravity environment in space. According to Huang, astronauts stay underwater in suits weighing over 100 kilograms for six hours at a time. Water resistance(阻力)and the heavy suit make every move exhausting. “Nie Haisheng, one of the astronauts, once reported a two-kilogram loss in weight after one underwater training exercise,” said Huang. Each astronaut receives training for at least three and a half years before having the chance to go to space.

7 . About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this section by 40% in the US. The approach is called ATES, short for aquifer thermal energy storage (含水层热能储存).
“We need storage to absorb energy from the sun and wind. It’s crucial to creating affordable, reliable, and deeply environmental-friendly electricity systems. Most people are interested in batteries and other kinds of electrical storage. But we were wondering whether there was any opportunity to use geothermal (地热的) energy storage,” said first author A.T.D Perera. “With ATES, energy can be stored for a long period of time, without adding an additional burden to the grid (输电网).”
ATES is a pleasantly simple concept that takes advantage of the heat-absorbing property of water and the natural geological features of the planet. You simply pull existing underground water up and heat it at the surface in the summer with environmental heat or energy. Then you send it back down. It stays fairly hot because the Earth is a good insulator (绝热体).
“Unlike above-ground tank-based water or ice storage systems, ATES will not need space. It’s also more efficient and can support larger communities in cooling or heating than traditional geothermal heat pump systems that rely on heat moving with the underground soil,” added co-author Hong Tianzhen.
A major beneft of ATES is that it will become more efficient as weather becomes more extreme in the coming years due to climate change. The hotter summers and severer winters could increase the amount of free thermal energy that can be stored with ATES. “It’s very much a realistic thing to do and this work is really about showing its value,” said Perera. “This technology is ready to go, so to speak. We just need to do it.”

8 . The Kirtland’s warbler(莺) has required protections since the foundation of Endangered Species Act (ESA), but that’s about to change. The Fish and Wildlife Service (FWS) today announced it is removing the songbird from the endangered species list.
“The effort to recover the Kirtland’s warbler is a successful example of how to save endangered species,” said Margaret Everson, director of FWS. “The Kirtland’s warbler has responded well to active management over the half century.” In 1971, the Kirtland’s warbler population declined to approximately 201 singing males and had habitats in only six counties. By 2015, the population reached 2,383 singing males and had spread geographically. FWS regularly noted the singing of male warblers during the breeding season made counting possible.
“The negative factors for the development of the recovery plan have been dealt with,” said FWS. Modern wildfire suppression(扑灭) practices enabled the growth of the jack pine forests favored by the species, FWS noted. Michigan state has replanted approximately 90,000 acres of Kirtland’s warbler habitat over the past 30 years. Timber(木材) incomes offset the cost of replanting jack pine needed to support a survivable bird population.
But while the bird is falling off the ESA list, officials note that it remains a “conservation-dependent species”. Conservation of the Kirtland’s warbler will continue to require an approach for carrying out future conservation work, like partnerships and enough financial support, FWS stated. Under the Endangered Species Preservation Act of 1966, the Kirtland’s warbler was officially listed as an endangered species in 1967.
“This remarkable bird has a most impressive success story that illustrates effective conservation and cooperation at work,” added Heather Good, executive director of Michigan Audubon. Shawn Graff, vice president of American Bird Conservancy’s Great Lakes program, pointed out the delisting(除名) is “cause for celebration and proof that the Endangered Species Act works.”

9 . As a young girl growing up in France, Sarah Toumi dreamed of becoming a leader who could make the world a better place. Her passion to help others was awakened when, from the age of nine, she accompanied her Tunisian father to his birthplace in the east of the country during holidays. There she organized homework clubs and activities for children.
Toumi witnessed first-hand the destructive effect of desertification (沙漠化). “Within 10 years rich farmers became worse off, and in 10 years from now they will be poor. I wanted to stop the Sahara Desert in its tracks.” A decrease in average rainfall and an increase in the severity of droughts have led to an estimated 75 percent of Tunisia’s agricultural lands being threatened by desertification.
Toumi recognized that farming practices needed to change. She is confident that small land areas can bring large returns if farmers are able to adapt by planting sustainable crops, using new technologies for water treatment and focusing on natural products and fertilizers rather than chemicals.
In 2012, Toumi consolidated (巩固) her dream of fighting the desert. She moved to Tunisia, and set up a programme named Acacias for All to put her sustainable farming philosophy (理念) into action. “I want to show young people in rural areas that they can create opportunities where they are. Nobody is better able to understand the impact of desertification and climate change than somebody who is living with no access to water.”
By September 2016, more than 130, 000 acacia trees had been planted on 20 pilot farms, with farmers recording a 60 percent survival rate. Toumi estimates that some 3 million acacia trees are needed to protect Tunisia’s farmland. She expects to plant 1 million trees by 2018. In the next couple of years, Toumi hopes to extend the programme to Algeria and Morocco.
