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.

Some students said teachers often overrun by a few minutes, and that some start their classes a few minutes before the breaks are scheduled to end. In these cases students do not even have time to go to the toilet.
A mother of a primary school student in Hangzhou, Zhejiang Province said her child’s school does not allow students to leave the classroom building during breaks. They are also forbidden to jump, run around or speak loudly.
The issue has caused a heated discussion on social media platforms.
“Teachers do not want to supervise students during class breaks. However, if students have accidents, some parents will still hold schools accountable,” said one netizen in a comment that received more than 10,000 likes. Another said, “Teachers are also tired, but the school makes such a requirement, and they have to follow.”
An official from the Ministry of Education said that it is important for schools to ensure students have time to rest during class breaks, which can help students relax, be healthy and avoid myopia (近视).
The ministry attaches great importance to class breaks, the official said. Apart from breaks between classes, schools should also make sure students have a 30-minute break each day for exercise. The ministry will urge local authorities and schools to implement the policies and prevent the practice of restricting class breaks in the name of “ensuring students safety”, the official said.

【推荐2】With his feet six inches apart, toes straight ahead, knees slightly bent, arms out at his sides, eyes forward, and his weight evenly distributed between your skates, Richard Epstein, from Santa Fe, New Mexico, has gone popular online thanks to a video his daughter Rebekah Bastian shared on social media.
In a post on Twitter, Rebekah uploaded a clip of her dad taking part in an ice skating performance with his teacher. She captioned the tweet, writing: “My father is 77 years old and has stage 4 cancer. He decided to learn how to ice skate a few years ago, and just did this performance with his teacher last month. For anyone that thinks it’s too late to try something new.”
Speaking to The Mirror, Rebakah explained how her dad, a retired astrophysicist and applied physicist, first started trying ice skating about 10 years ago. He then suspended it for several years, before deciding to commit to learning and enrolling in lessons with a teacher named Teri Moellenberg, three years ago. Richard now practices twice a week and is “really enjoying it”, with plans to keep on taking lessons. He was diagnosed with Chronic Lymphocytic Leukemia (CLL) about 2.5 years ago. That got under control with some medication. So far he’s still feeling good and is on some medications to slow that down. He’s a great example of keeping learning and making a new start and he’s certainly inspired that within her daughter.
Rebekah also added: “The company that I founded, OwnTrail, is all about there not being one right path through life, and embracing our ever-changing journeys. My father’s energy has definitely inspired that belief in me.”

【推荐3】The 24 solar terms (节气) originated and was firstly used in China. It was created thousands of years ago on the basis of practical needs of agriculture. Ancient Chinese people used it to guide agriculture production, special climate signs and even healthy living tips. The 24 solar terms was added to UNESCO’s world cultural heritage list in 2016.Now, it has been brought to life thanks to a creative designer from Southwest China’s Guizhou Province.
On the eve of the Qingming Festival, Shi Changhong released (发布) his version of reproduced and packaged characters for each solar term in the form of “moving art” of Gifs. Since their first release on Zcool on March 29, the Gifs have won great praise among the general public and quickly flooded social media with millions of hits during the festival period.
To maximize publicity, Shi released his work in three forms: video, animation and picture. The background sounds add to the brilliance.
“When I watch the short video, I can strongly feel the Chinese style elements hidden in them. And it is really cool to liven up Chinese traditional culture in such a unique way,” WeChat user Xiao Feifei said.
“It is really a comfort to me to see so many people like my latest work. To be honest, it would really surprise me if the work does not arouse great interest among Chinese people. The 24 solar terms is a deeply rooted concept that covers the essence of Chinese wisdom. However, only a small portion of people know all the names or the correct order of those terms. My intention is to increase Chinese people’s self-awareness to learn more about our traditional fine culture. Actually, the 24 solar terms work is only a part of my whole design program ‘Charm China’, which I started over a year ago,” Shi told China Daily.

【推荐1】Kew Gardens is not only a popular tourist destination in London, but also a botanical garden and a research center that has the largest collection of living plants at a single site. So, let’s explore the Royal Botanical Gardens with CGTN’s reporter Robyn Dwyer.
Palm House
The first stop is the Palm House, a giant indoor rainforest with a wide range of plants. Visitors can enjoy these unique plants while researchers can study the secrets of these plants. Eatable plants such as cocoa tree and African oil palm are all preserved here to keep the diversity of food resources. At the same time, it houses many medical use plants, including some that are used to treat cancer.
Temperate House
Known as the world’s largest Victorian glasshouse, the Temperate House is home to 1,500 species of plants from temperate regions of the world. Some of the species kept here have gone extinct in the wild, such as Encephalartos woodii, a cycad from South Africa. And some are already extinct like Saint Helena olive, but the Kew has stored its DNA.
Mediterranean (地中海) Garden
In the Mediterranean Garden, one can see plants from the Southern Europe, such as rosemary, olives and cork oak. Walking in the garden, one can feel the non-indoor vibe (氛围) of the Mediterranean and learn about the economic as well as scientific uses of these plants.

【推荐2】For many years, scientists saw trees as independent living things. Each tree in the forest was trying to get light, water and nutrients. Trees competed for resources.
In forests, fungi connect trees through underground networks. Trees’ roots branch out in all directions. The same soil is home to fungi, which can grow on and around tree roots. The fungi grow in thin threads (线状物). As they grow, the threads can link to numerous trees. The fungi create webs between trees known as mycorrhizal (菌根) networks.
The fungi in a mycorrhizal network link the trees together.
Mycorrhizal networks are not always cooperative. Some plants will use the networks to take nutrients from their neighbors. Some flowers will steal food from other plants.
A.Trees also send messages through the networks. |
B.Networks can even connect different species of plants. |
C.Scientists think the fungi are important for healthy forests. |
D.Trees can share sugars, nutrients and water with one another. |
E.However, scientists are discovering that trees may actually work together. |
F.There are also plants that send poisonous substances through the networks. |

【推荐3】Four Best Plants to Give as Gifts
Choosing a gift for someone is always a challenge. Giving plants is one way to try if the recipient is already a plant-lover. Here are some sure to impress as thoughtful gifts.
Jade Plant
The jade plant is a large succulent (肉质植物) that makes a perfect gift for someone who’s mastered parenting succulents. With a woody stem (茎), it looks like a tree once growing tall enough. Besides occasional watering and a bright window, the jade plant has few other requirements. A good challenge for ambitious owners is to regularly cut off its heavy leaves to reduce weight.
Christmas Cactus
This is a succulent with eye-catching flowers that appear in winter. You might assume it a picky plant, but nothing could be further than the truth. It prefers bright, indirect light and grows well in average potting soil. This plant prefers a steady watering schedule, especially in winter. To encourage more growth, plant it in a hanging container that allows its branches to hang down.
Paperwhite
Some people just aren’t interested in keeping houseplants around long-term, and paperwhite flowers are an excellent gift for anyone you know who fits this mould. Paperwhites grow from bulbs (鳞茎) and will produce flowers out of season. The roots need to be kept relatively damp, but once they are blooming (开花), there’s not much that can go wrong. They can be replanted outside after they have run their course.
Corn Plant
The corn plant is forgiving of variable light conditions and watering routines. It grows slowly, but can reach a height of four to six feet, and can make an impressive floor plant. Its leaves turn paler in direct sunlight to reflect the extra light, and darker green in shady conditions to maximize sunlight absorption.
1. Which plant requires practised gardening experience?A.Jade plant. | B.Christmas cactus. | C.Paperwhite. | D.Corn plant. |
A.By replanting it outside before blooming. | B.By watering it regularly during blooming. |
C.By cutting off most of its heavy leaves. | D.By making its branches grow upwards. |
A.The frequency of watering. | B.Its flowering time. |
C.Its rate of growing. | D.The amount of sunlight. |
