1 . There are two distinctive types of electric buses making their way along Nanjing Xi Lu, one of Shanghai’s busiest roads. The first is a fleet of blue trolleybuses that serve bus route number 20, a line set up by a British-run transport company in 1928. They use poles to receive electricity from wires overhead and have kept the route running in this way for nearly a century. But while the historic electric buses are a reminder of Europe’s past technological innovation, the new buses traveling alongside them are symbols of China’s contemporary net-zero ambition. These modern electric buses powered by lithium batteries (锂电池) , were introduced in Shanghai in 2014. They offer a smoother ride, especially during starts and stops. Widely used across China, these buses are key to the country’s EV transition and are influencing the global shift towards green transportation.
The most recent data available shows that China in 2018 was still the second largest source of carbon dioxide emissions in the global transport sector, responsible for 11%, and behind only the United States, which accounted for 21%. After around two decades of government support, China now boasts the world’s largest market for e-buses, making up more than 95% of global stock. At the end of 2022, China’s Ministry of Transport announced that more than three-quarters (77% or 542, 600) of all urban buses in the country were new energy vehicles. The speed of this transition was remarkable.
So far, however, the Chinese cities with the most successful e-bus introduction — such as Shenzhen, Beijing and Shanghai — all have moderate weather and are relatively flat. To take its e-bus campaign to the next level, China faces challenges. For one thing, it is difficult to bring fleets to cities such as Hong Kong, which — like London — have double-deckers. These two-storeyed vehicles are “very hard” to electrify, because they are heavier, use more energy, and so need bigger batteries, reducing the number of passengers they can carry. Cold weather is a problem, too, as it can make a battery’s charging time longer and its range shorter. The reason China has not achieved 100% electrification for its buses is its northern regions, which have cold winters, says Xue Lulu, a transportation expert at the World Resources Institute China.

2 . If you haven’t taken down your Christmas tree yet, no worries. Here’s an idea: have you ever thought about eating it?
Julia Georgallis has some recipes. Over the last five years, she’s been preparing carefully for Christmas dinners in London with a friend. “How can we make something sustainable around Christmas time? What can we cat? What’s the thing that no one eats and that somehow represents Christmas? And then we just decided on Christmas trees,” Georgallis says.
She turned it into a book, How to Eat Your Christmas Tree. And her idea is that it’s not that odd. Some people enjoy Christmas wine. Some people like to go shopping and most people can get behind saving the planet.
“What I aimed for this book to do, really, was to get people thinking about the odd ways that they can be more sustainable in their daily lives,” Georgallis says.
“Eating Christmas trees isn’t going to save any animals in danger or freeze any ice caps. But if we start to think about everything that we do as a whole, then that builds up, you know, and that helps,” she says.
Most of the recipes in her book use the needles from the tree. “You’d use the needles like a herb,” she says.
“And different Christmas trees kind of have different flavors. They’re quite subtle, but they do have different flavors. So fir (冷杉), which is a really popular choice of Christmas trees, gives people better feeling and atmosphere. And then you have pine, which is a little bit more delicate.”
A warning: some Christmas trees are poisonous if eaten — like cypress and cedars. And be sure your tree wasn’t sprayed with pesticides (杀虫剂) and other chemicals. “So if you have any doubt that your Christmas tree might not have been grown to eat, then maybe don’t eat it,” Georgallis says.
And, of course, don’t even think about eating your artificial tree!
So, with all those instructions and with the appropriate tree, what could we cook? Well, Georgallis’ book has all sorts of recipes for different foods and drinks. Let’s open up the world’s cuisine with simple ingredients!

3 . Researchers in Australia have identified enzymes (酶) in the body of certain beetle larvae (甲虫幼虫) that can degrade or break down plastic. In a study published in Microbial Genomics, they write that these “superworms” could help reduce plastic waste in the future.
“Superworms are like mini recycling plants, cutting up the polysyrene (聚苯乙烯) with their mouths and then feeding it to the bacteria in their stomach,” said Chris Rinke from the University of Queensland in Australia. “The breakdown products from this reaction can then be used by other microbes to create high-value chemicals.”
In the study, scientists divided beetle larvae into three groups, feeding one group wheat bran, one polystyrene and one nothing. Over three weeks, they monitored their growth. “We found that superworms fed a diet of just polystyrene not only survived, but even had marginal weight gains,” said Rinke. “This suggests the worms can get energy from the polystyrene, most likely with the help of their stomach bacteria.”
On the other hand, the plastic-fed worms gained much less weight and were overall much less healthy than the bran-fed ones, though better off than the starvation group. After three weeks, some larvae were also set aside to grow into beetles, according to the study. About 93% of the bran-fed larvae formed adult worms, while about 67% of the plastic-fed larvae and 10% of the starved larvae formed adult worms.
The researchers investigated the superworm’s stomach bacteria to find the specific enzymes linked to plastic degradation, writes Fionna M. D. Samuels for Scientific American. The enzyme that degrades the polystyrene appears to live with the stomach bacteria, not the worm itself.
Polystyrene is one of the most common plastics used today. But it’s not very chemically reactive, and breaking it down with industrial recycling methods takes high heat. So, researchers have been looking for plastic-degrading enzymes and bacteria for years.
Further research will still need to be done to figure out how to employ these worms, bacteria and enzymes in recycling facilities.

4 . For Cruz, who grew up in Peru’s mountainous region of Cuzco, fog represents a massive opportunity. As a boy, he had to hike for more than an hour every day across hills to collect water from the nearest source. But over time, he realized that during the rainy season, droplets of water would gather in the large leaves of banana trees. So one day he and his father tried to build a canal system with the leaves to collect water and it turned out a success. But afterwards, he moved to Lima at the age of 25.
There, shocked by the water shortages and expensive water supply that some of the city’s poorest residents were faced with, Cruz set up El Movimiento Peruanos sin Agua in 2005. The idea was to deploy the method he learned in his hometown on a larger scale, which would provide free, independently sourced and easily accessible water to those who needed it most. He began installing (安装) a traditional fog catcher model developed in the 1980s.
At the highest point of Los Tres Miradores, there is a curious set of large structures that resemble a fleet of ships in the sky. They are so-called “fog catchers”. Netted devices, made of high density Raschel polyethylene and spanning several meters wide, are lined up at the top of a misty mound and linked by a network of tubes that lead to storage containers. The 40 fog catchers there provide enough water for 180 families, whether to bathe, clean, drink or to irrigate crops on small garden patches.
Supporters believe that fog catchers have the potential to improve water supply for communities around the world among the ever-challenging circumstances. German researcher Lummerich says, “They are cheap, easy to construct.” In a world searching for water supply systems, it is one important puzzle piece that can make an essential difference locally.
However, there are some issues. For one, fog catchers require space, which is not always easy to come by in cities, let alone urban slums. At the same time, fog catchers must be properly cleaned and maintained to stay effective. Most crucially, appropriate climate conditions are required. Fog isn’t everywhere.

6 . Finding a California condor in the wild would be the most unusual treat. perhaps even more unusual than finding a wolf in Yellowstone National Park. In fact, the wolf was what opened my eyes to the fact that humans could bring an animal back to the place where it had disappeared.
In 1987, there were only 27 California condors left, none of which were in the wild, only in captive breeding programs, It was those breeding programs that contributed to their population rise, enough that by 1991 some of them could be freed into the wild.
Still, the hope of seeing a California condor, which remains an endangered species, is very low, let alone getting a photo of one. California condor population dropped mostly due to human factors, such as poaching and living areas destruction-these are challenges California condors still face today.
Although this is just a bird’s-eye view of the challenges California condors face and there are many others, it is part of why the opportunity to work with the US Fish and Wildlife Service team and their partners helping their recovery is so special to me as a photographer. I am not only able to photograph the birds in their wild living areas, but also understand and record how difficult the work is of those people on the front lines of the protection.
I am grateful for the work of the team, and my hope is that California condor population will continue to rise allowing future generations an opportunity I never had when I first got here-to look to the sky and see one flying around.

7 . Monkfish are low in calories and they are easy to cook. They can be cut into pieces, mixed with egg whites, cornflour and salt, and then put into boiling water for a few minutes. There is only one problem with monkfish: they are ugly. With their eyes sticking out and wide mouths full of sharp teeth, they are frightening.
In the Netherlands, fishermen who caught them used to throw them back. They are still usually sold without their heads, but the days of throwing them away are long gone. Japanese diners love the fatty liver; while Italians may still call them toad tails, that doesn’t stop them from eating the fish. People have been encouraged to eat more monkfish, as well as other unattractive creatures — in order to ensure the biodiversity of the ocean environment.
There are more examples for sea animals going from “purposely avoided” to “willingly consumed”. In America, lobsters used to be fed to prisoners — a result of their abundance but also, no doubt, because they are difficult to eat and look frightening. Not until the late 19th century did they become fantastic dish. Today they are so desirable that Maine, where most American lobsters are caught, has the images of these creatures printed on many of its vehicles.
Sometimes fashion goes the other way. Turtles were plentiful in early America, but in the 19th century they became fashionable: few foods were more recommended than turtle soup. Americans ate some species of turtle nearly to extinction. Yet today turtle-eating is more closely associated with remote and uncultured areas.
Among cooking choices, people prefer the rare and the beautiful one than the unattractive one. But such narrow-minded food choices can have bad results: some species may not survive human preference for them. Better to stare into monkfish’s eyes than to contribute to the permanent loss of a species.

9 . Scientists have reported that the sea ice in Antarctica (南极) is at a record low level. Antarctica is a great, icy land, surrounded (围绕) by the huge Southern Ocean. The ice in Antarctica doesn’t just cover the land. There’s also a large area of sea ice on the ocean’s surface.
Every year, the sea ice at the South Pole goes through a cycle. In the summer, the huge sea ice melts (融化) to its smallest point. Over the colder winter months, the sea ice grows and grows until it covers a wide area. Usually, the sea ice covers the greatest area around September 23, as winter ends at the South Pole.
Scientists have been measuring the area of the sea ice in Antarctica since 1979. For most of this time, Antarctica has seemed to be almost unaffected by the changing weather conditions experienced in other parts of the globe. That began to change around 2016. Now, for several years, the area of Antartica’s sea ice has been shrinking.
This year, the US National Snow and Ice Data Centre (NSIDC) reported that Antartica’s sea ice covered its greatest area on September 10 — almost two weeks earlier than normal. And the sea ice was at a new record low-not just by a little bit, but by a lot.
The last time Antartica’s low sea ice set a record at the end of winter was in 1986. And this year, there’s about 398, 000 square miles less sea ice than in 1986.
Scientists are still trying to understand what is driving the change in Antarctica. One likely direct cause for the change is the rising temperatures of the world’s oceans. Ted Scambos, a research scientist at the University of Colorado, says Antarctica’s ice levels have always changed some, but the sharp loss this year is “pointing towards warmer ocean conditions around the continent.”
The new low record has concerned the scientists. Scientists are working hard to better understand Antarctica. They don’t know yet if this is just a short-term problem, or part of a long-term shift (转变) towards less sea ice in Antarctica.
