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.

2 . 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.

3 . 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!

4 . The opening of California’s commercial crab season, which normally starts in November, is delayed once again to protect whales searching for their prey (猎物) along the coast.
California has been affected by a marine heat wave since May. The Blob, as this mass of warm water has become known, is squeezing cooler water preferred by whales and their prey close to shore, where fishermen set their traps. This crowding can lead to tangle (缠结) between whales and fishing equipment, endangering the animals’ lives and requiring rescue missions.
In a new study, scientists say they can now use global temperature models, commonly used in climate science, to predict up to a year in advance when hot ocean temperatures raise the risk of tangles between whales and fishing equipment.The tool analyzed in the new study, called the Habitat Compression Index, works by feeding sea-surface temperature measurements into an equation (方程式) that estimates the likelihood of whale habitat shrinking closer to shore.Regulators and fishermen agree that the new forecasting research could help them walk the tightrope between protecting whales and protecting local livelihoods (生计).
Mr Ogg, a commercial fishing boat captain, describes himself as a conservationist who doesn’t want to see whales harmed.“Fishermen have a big motivation to protect the natural environment,” he said, “because that’s where they make their living.” Previously, the challenge was adapting to changing conditions and fishing regulations on short notice, especially for smaller business owners and their crews.“One of the biggest problems we had was the unpredictability,” Mr Ogg said, “We were living from week to week then.”
Though scientists have shown the Habitat Compression Index can now forecast months in advance, state officials would probably wait to see conditions in real time before making decisions about the crab fishery, said Ryan Bartling, an environmental scientist at the California Department of Fish and Wildlife.

5 . The fruit-tree pinhole borer (针孔蛀虫), as its name implies, makes holes in fruit trees. It lays its eggs and raises its young in the galleries thus created . Yet the beetles (甲虫) do not feed directly on the wood they bore into. Instead, they devour fungi (真菌) that grow on the wood thus exposed.
Researchers have long suspected that this is a form of farming, because they have evidence that the beetles carry spores (孢子) of their preferred crop, R. sulphurea, into their smallholdings—in effect, sowing it there.
Observations of natural fruit-tree pinhole-bore r dwellings suggest that R. sulphurea grows in them more abundantly (大量地) than might be expected, given all the fungal competition around—but not why. To check whether the beetles are, indeed, weeding their crop, Janina Diehl and Peter Biedermann of the University of Freiburg did an experiment.
In the laboratory, they had mother beetles of the little wood bore restablish nests, in which the typical fungal gardens formed. But before the beetles had started laying their eggs, they collected all of the beetles and then returned half to their dwellings while leaving the other nests empty. Genetic analysis of the fungal gardens after 40 days showed that the presence of the beetles had greatly changed the fungal community. Twenty days after that, they sampled the gallery walls for fungi.
As they had hoped and expected, R. sulphurea was much more abundant in beetle-tended galleries than in those without residents. In the former, it made up half of the fungal mass extracted. In the latter, less than a third. These beetles are indeed weeding their crop.
“Further research into how exactly the beetles suppress the growth of weed fungi could alsoprovide worthwhile insights for human agriculture, which is struggling with weed resistance, for example,” says Biedermann. “It’s highly exciting for us to see how nature has been doing this for 60 million years. We humans can still learn something from these mechanisms.”

6 . Several security guards of residential compounds in Beijing and workers were seen shoveling snow and some parked vehicles were covered by thick overnight snow. The first snowfall of winter arrived in Beijing early Monday, covering the Chinese capital with a mantle (披风) of white overnight and plunging (使……下降) the city into freezing temperatures, with even colder weather coming this week in northern China.
Snowfall reached 5.8 mm on average by early Monday, with the highest snowfall of 10.2 mm recorded in Fangshan district, Beijing Meteorological (气象的) Service data showed. Beijing typically sees its first snow of the season between late November and February, or even none at all. More snowfall is expected this week, with temperatures seen further sliding to as low as -20°Celsius. The Chinese capital last saw such similarly extremely cold weather on Jan. 7, 2021, when the temperature dropped to -19.6℃.
The cold snap (寒潮) in Beijing this week, compared with the autumn-like conditions a week ago, mirrored the sharp swings in temperatures recently. In October, Beijing experienced one of its warmest Octobers in decades in a year of weather extremes.
On Monday, the government warned of road icing in large parts of the city of nearly 22 million, with authorities shutting some expressways or partially closing sections. By 10 a. m. local time, 62 out of a few hundred flights had been cancelled at the Beijing Capital Airport. Railway authorities enforced speed limits on lines connecting Beijing and Guangzhou in southern China, causing delays in some passenger trains. By 7 a. m. Monday, more than 180 bus routes in Beijing had been suspended.
The official Beijing Daily reported that vegetable stocks were enough, hitting this year’s highest daily market volume of 23,800 tons, as merchants stocked up (备货) ahead of time. Huang, a Beijing resident working in the internet sector, said the snow in Beijing came early. “Normally, it doesn’t snow until the Spring Festival,” Huang said, referring to the start of the Lunar New Year, which typically falls in January or February.

7 . For the first time in about 100 years, a rare bird called the takahē is walking freely along the Lake Whakatipu Waimaori Valley in New Zealand after 18 captive birds were released into the wild. The area is also home to a Maori tribe called Ngai Tahu, which has spent years campaigning for the birds to return to their land. The Maori are New Zealand’s Indigenous people (first people known to live there), and they consider the takahē bird to be “taonga”, meaning a treasure.
Takahē are large, round, flightless birds with red legs, and they have lived in New Zealand since prehistoric times. Like many New Zealand birds, takahē evolved to be flightless because there were no mammals to compete with. When Europeans arrived in New Zealand, however, predators such as cats and ferrets were introduced and killed off many flightless birds. Takahē were declared extinct in 1898, but a small number of the birds were discovered in 1948 in a remote part of the Murchison Mountains.
Since then, conservationists have been trying to restore the takahē population in captivity. They gathered the bird’s eggs in order to keep the chicks safe from predators. The chicks were raised by volunteers, who fed them while wearing sockpuppets on their hands to imitate the parent birds. There are now about 500 takahē birds in captivity. Several pairs of adult birds have been released into the island’s sanctuaries and national parks. Experts will monitor them to see how they adapt to their new environment. If everything goes well, they hope to release seven more birds this month and 10 young birds next year.
Ta Tipene O’Regan, an elder of the Ngai Tahu tribe, helped to release the birds. He told The Guardian newspaper, ”There are few things more beautiful than to watch these large birds running back into lands where they haven’t walked for over a century. ”O’Regan said, “It’s an absolute joy. ”

8 . Growing up on a mountain farm in Tyrol, Fritz enjoyed watching how cows and horses interacted with each other more freely, once they’d been led out of the barn and into pasture. It was what he observed in his boyhood that took root in his pursuit of becoming a biologist. After he finished his study at university. Fritz landed work at Austria’s Konrad Lorenz Research Center, raising raven chicks by hand and teaching graylag geese how to open boxes as he pursued his PhD. Working this closely with free-living animals was exactly what he’d dreamed of as a boy.
In 1997, a zoo gave the research center its first northern bald ibis chicks (隐鹮) Nowhere near as teachable as geese—and not even close to super intelligent ravens—the ibises frustrated most of the scientists. But Fritz was fascinated. He devoted himself to taking care of them. After the ibises were first released back into the wild more than 20 years ago, Fritz learned that spending generations in zoo hadn’t reduced their drive to migrate (迁徙), though it did leave them geographically uninformed. In their search for “south”, some ended up in Russia. What the ibises needed, Fritz thought, was a guide.
Fritz decided he would teach the birds a new, safer migration route by guiding them himself in a tiny aircraft. And he was confident he could succeed in this daring, unconventional plan—because he had done it before. “Around that time, the movie ‘Fly Away Home’ was a huge hit with us biologists,” Fritz says. When he announced that he’d do the same with the ibises, he was initially laughed at. But Fritz didn’t give up. He modified an ultralight aircraft so it would travel at speeds slow enough for his winged students to keep up. He had been his young pupils’ only provider of food, love and hugs since they were just a few days old, and the ibises eagerly followed their teacher, who just happened to pilot a fairly noisy machine.
In 2004, three years after some initially bumpy (颠簸的) experiments, Fritz led the first batch of birds from Austria to Italy, and has since led 15 such migrations. Over that time, he has rewilded 277 young ibises, many of which then started to pass the route on to their own young.

9 . Conservation organization Plantlife is urging people to put away their lawnmowers (除草机) for a month and let wild flowers grow instead, as part of its No Mow May project.
Leaving the grass uncut will create a habitat that will benefit bees and other insects, the organization says. Plantlife says lawns could be biodiversity hot-spots if left alone. It says those who participated in its campaign last year reported the growth of more than 250 plant species on their lawns. Among these were wild strawberry and wild garlic. There were also sightings of declining species like green-winged orchids.
One gardener who has been enjoying a more relaxed approach is Tom Jennings, 45, from Buckinghamshire. He says it’s a chance to reconnect with the natural world. “Those fascinated by neat gardens use not only lawnmowers but chemicals.” says Tom.
After letting his back garden grow out, Tom witnessed an explosion of wild flowers—important for pollinators (授粉者) such as bees. Tom says he’s been shocked at how quickly insects have returned to his back garden: an encouraging signal given the global decline of insect populations.
According to Colette Webb, 42, who lives in West Sussex, there are added benefits to letting nature gradually take its course in the garden. “It saves you a bit of time and arguments with the husband about getting the lawnmower out—something my husband hates doing,” she says. “There’s a part of me that thinks the garden is really messy, but when you sit there for some time a day and look at what’s it’s supporting, you realize it’s for the benefit of nature.”
But not everyone is on board with the idea, says David. One of his neighbours is pursuing their own re-wilding project in their own garden—but the other is yet to be convinced. “And my mother, who’s 81, still says it looks untidy,” he laughs.

10 . Recently, China has announced the list of the first five national parks. Each of them is divided into two parts — the core protection area and the general control area. In the core protection area, only research and surveillance (监视) in science are allowed. And the general control area is open to the public, allowing travel activities such as camping and hiking. In the future, national parks are expected to be natural classrooms. People can learn about different kinds of animals and plants through eco-friendly travel activities.
Three River-Source National Park on the Qinghai-Tibet Plateau is the largest national park in China. Because it is home to the sources of the Yangtze, Yellow and Lancang rivers, people call it “China’s water tower”.
Northeast China Tiger and Leopard National Park is in Heilongjiang and Jilin Provinces. It covers an area of 14,100 square kilometers. It is our country’s biggest and only place for wild Siberian tigers and Amur leopards to live in.
Wuyi Mountain National Park in Fujian Province is a UNESCO natural and cultural heritage site. The forest makes up over 96 percent of the park. The park is the paradise of birds, kingdom of snakes and world of insects. You can also see the Danxia landform there.
Giant Panda National Park connects panda habitats in Sichuan, Shaanxi and Gansu Provinces. Inside the park are more than 1,600 wild giant pandas. They make up over 70 percent of the pandas in China.
Hainan Tropical Rain forest National Park is the largest tropical forest in China. There are more than 400 kinds of plants that can only be found in Hainan.
