1 . In late June, the US government agreed to allow two companies Upside Foods and Good Mo. to sell chicken meat that has been grown in a lab. That makes the US the second country to approve (批准) lab-grown chicken.
Unlike normal chicken meat, lab-grown meat isn’t created by raising and killing chickens. Instead, it’s a meat product developed from animal cells (细胞) that are grown in a lab.
The first cells come from live animals. Scientists have known for a long time how to keep living cells alive and grow them in a lab. In this case, they choose cells that can grow quickly and will have good taste. The cells are grown inside a “cultivation (培植) room”, where they’re fed with everything they need to grow. In a few weeks, the cells grow into sheets of meat. The companies then form this meat into more familiar shapes that can be cooked and sold
The lab-grown meat is better for the environment than meat from animals. Raising animals for food uses plenty of land and water. It also creates a lot of pollution. Lab-grown meat can also help out in other ways. For one thing, raising animals for food is very hard on animals. They are often kept in small spaces, and are treated badly.
Since lab-grown meat is made from animal cells, it is very hard to tell it apart from actual meat. It looks, smells, and tastes like chicken. However, many people aren’t too interested in lab-grown meat. Lots of people believe that it just sounds strange.
Right now, the lab-grown meat is far more expensive than meat from animals. Now that the companies have been approved, they have the huge challenge of figuring out how to make much more meat far more cheaply. The two companies say the lab-grown meat will mainly be served in high-end restaurants. It will probably be a long time before you’ll be able to buy lab-grown chicken in stores

2 . In January, Rio Verde Foothills, an Arizona desert community, found itself in a bad situation: The water supply was cut off.
The community is made up of about 2,000 homes. For years, many in the community have depended on water trucked in from the nearby city of Scottsdale. which gets its water from the Colorado River. But the river is drying up Scottsdale says it has to save water for its own. Now people in Rio Verde Foothills must find a solution.
Some experts say the solution is to bring water from outside of the state. One idea is to build a desalination (海水淡化) plant on Mexico’s Sea of Cortez. The plant would take away salt from the water and supply that water to Arizona through a 200-mile pipeline (管道). Supporters say this could provide fresh water for about ten years.
Environmentalists say the desalination project would harm the planet in several ways. Some of the salt taken out of the Sea of Cortez might end up back in the ocean, harming wildlife. The pipeline would be harmful to land where people and animals live. And the desalination process uses lots of power. This would create greenhouse gases, which are causing the conditions that have led to Arizona’s water problems.
Margaret Wilder, a professor at the. University of Arizona, says the government should focus on cutting water demand (需求) rather than increasing supply. That would mean taking water-saving measures and controlling how many homes are built in the desert. “We need to start asking questions when people present us with unproblematic and carefree solutions to the water problem,’ says Wilder.
People in Tucson, Arizona, have found a solution to the city’s water shortage: rainwater Thousands of households are collecting it and using it for cooking, for drinking, and in their gardens.

3 . Ehrman Crest Primary School in Pittsburgh celebrated its opening in August. Three months later, the school, was put on the annual list of best inventions by a local newspaper.
The honor focused on Ehrman Orest’s creative design. There are large maps on the walls. Some classrooms connect to the outdoors. There’s also a rooftop garden. “We didn’t set out to be a best invention,” said Tracy Vitale, a teacher in the school. “We set out simply to replace an 84-year-old building.”
Kids played a key role in creating Ehrman Crest. After adults made decisions about basics, the builders met with students. “We really push hard on, ‘What do you expect a new school to be?’ and ‘What kind of environment would you love to learn in?’” explained Michael Corb, who is with the builder CannonDesign. “We want students’ ideas on how the school should look and feel.”
CannonDesign worked with the Children’s Museum of Pittsburgh on the project Anne Fullenkamp, a director at the museum, said the design process started with kids expressing their views. “We try to pool the students’ ideas,” she said. “The kids were given plenty of materials, such as photos and different colored cards. They picked these things and created their own storyboards. Wood was important to them, because it felt natural and was comforting. And they preferred calming colors, such as blues and greens.”
The result is a school with all the excitement of a children’s museum. There are traditional classrooms, but there are also places for exploration. “It’s such a proud feeling to walk into our school,” teacher Ryan Bonicky said. “The kids are just excited about learning.”
Ehrman Crest hopes that the physical space will have a positive influence on student achievement. “We built our dream school,” said Tracy Vitale. “I think the lessons learned here are ‘Be creative as adults’ and ‘Listen to children’”

When my daughter. Rachel was 6 years old, we went to the local shelter, looking for a perfect cat. We liked all the cats we saw there, but we especially loved one that was black with a small white tip to her tail, like a bright star in the night sky. We brought her home and called her Starry.
Starry was lovely. At night when we watched TV, she would come into Rachel’s lap and comfortably stay there. Starry always got her face close to Rachel’s, ending her love with a gentle touch on Rachel’s nose. Sometimes I felt so jealous (忌妒的) of their love. Although I was the one who tank care of the cat, feeding and cleaning it, Starry was clearly Rachel’s cat. Finally, I came to love watching their close relationship
My little girl grew up and went to senior high school. Starry and Rachel were still close, though Rachel spent less and less time at home. starry spent most of her day sitting on the sideboard in the dining room, looking out of the window into the backyard. I loved seeing her as I passed by her, for her shiny black coat almost sparkled (闪烁) in the sunlight and the white tip of her tail looked bright against the shining black of her body.
One Sunday morning, early in November, Starry got out of, the room before we could stop her. When Rachel came home from school, she went into the room with a worried expression. “Where’s Starry?” she asked. When we told her we didn’t know, she led us outside with her. There was a black cat lying on the street.

Walking might seem simple. “But it’s not,” explains Peggy Cawthon, a professor at Harvard Medical School. “It’s an amazingly complex behavior when we try to understand how to improve our lives as we age.”
Don’t stop exercising
Cawthon agrees that the worst thing a person can do is to stop exercising. “You’ll feel the effects almost immediately,” says Cawthon. Sitting for hours leaves her uncomfortable, and it’s the days when she types that her arthritis (关节炎) doesn’t cause much pain.
Train yourself to walk with skill
To truly improve your walking, you need to think like an athlete. Imagine you want to play tennis, but you have a bad backhand. Playing lots of tennis won’t fix the problem, Cawthon says.
Give your brain a boost (激励)
So when should we face the music about our mobility? There is no final answer for when walking problems begin to come up. “You should be as active as you can at any age,” Cawthon says, noting that people who are healthy in their 20s and 30s are best equipped to deal with future age-related challenges. “The best time to start is now. Next best is tomorrow,” she says.
