1 . In a Parisian old shoe factory on the city’s outskirts, a new kind of life is taking root. Neoplants, a startup from Paris, has developed a special houseplant that could potentially help improve indoor air quality by removing harmful pollutants.
The plant is a modified variety of one of the most popular and low-maintenance houseplants. Its DNA has been altered to enhance its capacity to absorb volatile organic compounds (VOCs) from the air we breathe inside our homes. These VOCs include substances like formaldehyde, benzene. toluene. ethylbenzene, and xylene, which are commonly found indoors and can be harmful in large quantities.
The genetic tweaking also allows the plant to convert the absorbed VOCs into substances it can use. such as sugars and carbon dioxide, which then fuel its growth. While Neoplants’concept is quite promising, proving its effectiveness is a challenge.
Plant shops often claim their greenery can purify the air, but much of this belief stems from research conducted by NASA back in 1989. They found that houseplants could indeed absorb certain toxins. However, achieving the same level of toxin removal as simply opening a window would require an impractical number of plants — anywhere from 10 to 1,000 per square meter.
So, does Neoplants’genetically modified houseplant offer a better solution? Field tests haven’t yielded definitive results yet, but there is hope for more conclusive testing in the future with the help of a new lab equipped with unique non-absorbent rooms that mimic real-life conditions . Additionally, the company is exploring potential applications for its gene-editing technology in areas such as carbon capture and phytoremediation, where plants are used to clean up contaminated environments
Neoplants is relying on patience and a bit of faith. It takes time for innovations to mature. “This will be the first time such a product exists.” says the company’s CEO. drawing a parallel to the early days of computers, which were not very powerful initially but still represented a significant breakthrough.
With Neoplants’ vision, the old shoe factory on the edge of Paris isn’t just a place where shoes were made; it’s where a novel approach to cleaning our indoor air is being cultivated — one that could someday make our homes healthier and more environmentally friendly.

4 . 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.

In Rome there was once a poor slave whose name was Androclus. His master was a cruel man, and so unkind to him that Androclus ran away. He hid himself in a wild wood for many days; but there was no food to be found, and he grew so weak and sick that he thought he would die. So one day he climbed into a cave and lay down to wait for death, and soon he was fast asleep.
After a while, a great noise woke him up. A lion had come into the cave, and was roaring loudly. Androclus was very afraid, for he felt sure that the beast would kill him. Soon, however, he saw the lion was not angry, but that his foot were hurt.
Then Androclus grew so courageous that he started to examine the lion’s paw to see what was the matter. The lion stood quite still, and rubbed his head against the man’s shoulder. He seemed to say, “I know that you will help me.”
Androclus lifted the paw from the ground, and saw that it was a long, sharp thorn that hurt the lion so much. He took the end of the thorn between his fingers; then he gave a strong, quick pull, and out it came. The lion was full of joy. He jumped about like a dog, and licked the hands and feet of his new friend.
The two became such good friends that Androclus found his new life a very happy one. One day some soldiers found Androclus in the cave and took him back to Rome. It was the law at that time that every slave who ran away from his master should fight a hungry lion. For each of these occasions, a fierce lion was locked up for a while without food, and a time was set for the fight.
Paragraph 1When the day came, thousands of people crowded in to see the fight.

The Internet’s carbon footprint is as bad as air travel. While it is difficult to measure precisely, estimates place it at over two percent of global greenhouse gas emissions(排放)—the same as the air travel.
Information may appear to spread around the world unseen to our eyes, but it actually passes through enormous data centers placed strategically about the globe, which store, organize and deliver everyone’s data. These centers are extremely energy intensive. In the EU, they consume close to three percent of its total energy usage and also require lots of water to prevent their computers from overheating. In the US, about a fifth of data centers draw water from already stressed water sources.
A typical spam email(垃圾邮件)emits around 0.03g of CO2 emissions, though longer messages read on a laptop can go all the way up to 26g. Now multiply that by 333 billion(roughly the number of emails that get sent every day in 2022). That puts all those work emails into perspective. One study found if every British adult sent one less “thank you” email a day, it would save 16, 433 tons of carbon a year. It even predicted that the ICT industry could account for up to a fifth of the world’s energy consumption by 2025.
However, there are measures that we can take to reduce our digital carbon footprint. For instance, you can unsubscribe from marketing and other spam emails and only subscribe to newsletters that you still regularly read. Have regular data checks where you delete old contact lists and other documents that no longer have any use. Keep a clean inbox and delete emails you no longer need.

10 . No matter how many times Sandy has rescued an animal, she never gets over the casual cruelty some people display toward unwanted pets. When she lost her own “angel” dog, she started Logan’s Legacy to help other pets in need.
Sandy recently received a phone call about a small dog, possibly a puppy, that had been abandoned on a street. Since she was too far to help on, she called a friend who lives nearby to get there as soon as possible. When her friend Tom arrived, he found a tiny dog curled(蜷缩)in a tight ball with the chain firmly tied to a tree. Someone had left food and water for her, but the puppy was too frightened to eat or drink. Once gathered up in a blanket and placed into the back seat of the car, she began to get weak quickly from dehydration(脱水)and exhaustion.
The moment she got some water and food, the puppy made a rapid recovery, and her lovely and sweet personality could finally shine! “We have named her CiCi,” Sandy added, “She is feeling so much better. She has been observed at my place and she is doing great. This sweet baby girl will never feel fearful again, and won’t ever be abandoned again.” After winning hearts at Sandy’s office, CiCi has been approved for adopting and will soon leave for her new life. Sandy and her fellow rescuers are trying their best to find her the perfect family to love her and treat her with the respect all living creatures deserve!
