1 . Paris mayor Anne Hidalgo has long worked to make her city less dependent on cars. She wanted to see more people using bicycles to get around. Over a number of years, the city government set limits on cars and increased the amount of bike paths from 200 kilometers to over 1,000 kilometers.

This year, Parisians are not complaining about too much automobile traffic. Instead, they say there are too many bikes. “Now, it’s really like a bike traffic jam(阻塞),” Thibault Quere, a spokesperson for France’s Federation of Bicycle Users, said. ”It’s kind of a good difficulty to have, especially when we think about what Paris used to be.”

Some famous roads along the River Seine are completely closed to cars. Now you see people riding bikes, running and walking with their families along the river. In another part of Paris, a bike path on Sebastopol Boulevard is one of the busiest in Europe, after opening in 2019. In one week in early September, it reached a record high of 124,000 riders.

The city will host the Summer Olympics in 2024 and plans to add more bike paths by then. Paris wants to reduce its pollution by half during the games, even as visitors from around the world will be in the city for the event. Organizers say all of the competition sites will be reachable by bike through a 60-kilometer network of bike paths.

The change to Paris, however, has not been easy. With more people using bikes, more people are making mistakes. Some of them are new to cycling and disobey traffic rules. But the environment may be improving. Cycling is good exercise and helps reduce pollution, which is still a problem for the large city. The French government blames atmospheric pollution for 48,000 early deaths in the country each year.

Hidalgo was re-elected in 2020 and plans to keep making what she calls a “Paris that breathes”. Her newest five-year bike plan includes over $250 million for more bike paths and bike parking. The new budget is an increase of over $100 million from her first five-year plan.

2 . The first wave of concerns over artificial intelligence(AI)in 2023 appeared soon after New Year’s Day when classrooms reopened and schools from Seattle to Paris started blocking ChatGPT, a powerful software based on AI large language models, because teenagers were using it to do their homework.

The AI large language models behind such products as ChatGPT work by repeatedly guessing the next word in a sentence after having “learned” the rules from a huge amount of/human-written works. Although they often get facts wrong, their answers appear so natural that Keven, their inventors begin to worry about their possible use for spreading false information.

People became more worried when various AI products started to create not just texts but novel images, music and human voices, which threatened the livelihoods of anyone who writes, draws or sings for a living. It led to strikes by Hollywood writers and actors and legal challenges from artists and bestselling authors. Some of the most respected scientists even warned that the technology’s unchecked progress was possibly threatening human existence. “In the longer term, they might manage our attention,” pioneering AI scientist Fei Fei Lisaid. “They would tell us which video to watch, which book to read or whose communication to respond as AI technology’s abilities improve rapidly. They could be a very good assistant, but also with really big risks.”

Li hoped that 2023 is going to be a year for people to think about what Al is, how to use it and what the effects are — all the good, the bad and the ugly.

“It’s easy to forget that they are not the first wave of AI products. Computer vision techniques developed by Li and other scientists have helped sort through a huge database of photos to recognize objects and individual faces and guide self-driving cars. Speech recognition advances have made voice assistants like Siri and Alexa a normal thing in many people’s lives,” said Tom Gruber, co-founder of Siri Inc.

3 . Schools in England will be offering British Sign Language (BSL) as a general certificate of secondary education(GCSE) subject as a way of boosting life skills and social inclusion (包容). This is something that comes after a decade of efforts that were backed by celebrities including Rose Ayling-Ellis, the stage and TV actor and model Tasha Ghouri, who has a hearing disability.

Ghouri has been encouraging people to learn sign language and told The Guardian that people often feel uncomfortable trying to speak to others who are deaf or hearing impaired (受损的). That’s because, she said, “they don’t know how to communicate”.

One in five people in the UK are deaf or hearing impaired according to the RNID organization. This includes at least 50,000 deaf children. It is estimated that 25,000 people use BSL as their main language.

Daniel Jillings started an activity when he was 12 to allow British Sign Language to be a core subject in school. Earlier in 2023, Daniel spoke to the government about the importance of deaf awareness in schools. Teaching BSL in the schools will allow hearing students to learn and that will lead to more social inclusion. “This is a significant moment in the history of the British deaf community, as it is a powerful step to equality,” he said.

While it is too late for Daniel, who was born without a cochlea (耳蜗), so he cannot use hearing aids and cannot speak, it is a welcome change for other students. The first GCSE courses are set to begin in 2025.

There are concrete benefits for students. Education secretary Gillian Keegan said, “Studying British Sign Language can open so many doors for young people, giving pupils an understanding of how thousands of people communicate and ultimately even expanding job prospects.”

South Koreans have enjoyed their first close-up look of new baby giant pandas at a name-revealing ceremony that is also     1     early celebration of the 100 days since the twins’ birth.

What to name the twin sisters was widely discussed among netizens after they were born on July 7 in theme park Everland. The names were     2     (ultimate) decided on through two public voting     3     (procedure). One is named Rui Bao, which means wise treasure, and the other is Hui Bao or shining treasure. Half a million panda lovers helped choose their names with a handful of lucky fans     4     (invite) to the ceremony. “They are even     5     (cute) in real life than they appear on screen,” said a college student in attendance.

The baby pandas,     6     have just begun teething and crawling, are very healthy. Everland has shared videos documenting the pandas’ growth online. The twins’ birth has gained 640,000 views since it     7     (upload). “This feels like a great opportunity to call for better     8     (preserve) of pandas,” said Donghee Chung, head of the park’s zoo. Chung noted that between 40% and 50% of panda births result     9     twins.

Everland said it would monitor the twins’ health     10     (determine) when the twins are ready to be open to the public.

6 . Twenty-two years ago, I won a Nobel Prize, together with Tim and Leland Hartwell, for our work on how cells control their division.

The prize changed our lives. Suddenly you become a public figure being asked to do all sorts of things: to give lectures, quite often on topics you know little about; to sit on committees and reviews you are not always well qualified to be on; to visit countries you have barely heard of. It is like having a whole new extra job, with upwards of 500 requests a year.

A recent study suggests that in general the extra commitments that Nobel winners take on result in fewer papers after their awards. There may be some truth to this given the extra demands on one’s time, but of course prestigious awards also allow new projects and research to be undertaken.

What effects did the Nobel Prize have on my subsequent career and work? It has certainly helped me to get scientific leadership positions. Within a year of getting the prize I was offered and accepted the presidency of Rockefeller University in New York. Having the prize also helps to get things done. For example, I have been involved in the merging of two separate cancer research charities to form Cancer Research UK. And it has helped me support causes I care deeply about. I became an ambassador for Ukraine education and science to help raise money for schools in that shattered country. Moreover, having a Nobel does help attract high-quality research colleagues. I have just started three excellent new PhD   students. It is a privilege for me to be able to pursue curiosity-driven research at this late stage of my career.

However, one thing I am glad to say that the Nobel Prize did not influence was peer review from my fellow scientists, assessing the suitability of my own research for publication, and my grant applications for funding. My rejection rates have remained essentially the same before and after the prize. And that, of course, is exactly how it should be.

7 . A team of leading environmental experts have warned that the current war on plastic is detracting from the bigger threats to the environment. In an article, they say that while plastic waste is an issue, its prominence in the general public’s concern for the environment is overshadowing greater threats, for example, climate change and biodiversity loss.

The team argue that much of the bad talk about plastic waste is based on data that is not always representative of the environments that have been sampled. The dislike of plastic associated with this could encourage the use of alternative materials with potentially harmful effects.

The authors warn that plastic pollution dominates the public’s concern for the environment and has been exploited politically, after capturing the attention of the world, for example, through the images of wildlife caught in plastic was alarmist headlines. They say small political gestures such as law banning cosmetic microplastics, taxing plastic bags, and financial rewards for using reusable containers, as well as the promotion of products as “green” for containing less plastic than alternatives, make people neglect other environmental problems that are not as noticeable as plastic pollution.

The article also highlights that plastic is not the only type of polluting materials, originating from human activity that pollutes the environment. Other examples include natural textile fibres such as cotton and wool, and brake-wear particles from vehicles — all of which are present in different places. The authors note that these materials are often much more abundant than microplastics and some are associated with “plastic alternatives” that are marketed as solutions to plastic pollution. The impacts of these materials are less well-known than plastic and microplastic pollution, yet they could have huge impacts.

The article states that solutions are likely to come from a greater focus on designing materials and products that can be recycled, that have their end-of-life, and that markets and facilities exist to recycle.

8 . The United Nations’ International Year of Soils is hardly a media favorite. Maybe it’s because many people are like me, who recall Mom’s words: “Take off your shoes! Don’t bring dirt into the house! “With all the challenges in the world today, why would we recognize soils?

Simply put, soils are literally the base that humans stand on. Ignoring the importance of this meter-thick skin covering our planet is like ignoring the importance of the air we breathe.

Without healthy soils, we would not be here.

Soil provides the structure and nutrients needed to grow our food. It stores water that satisfies the thirst of the environment, agriculture and humans. It houses the largest amount of carbon (碳)on land, keeping the climate from warming even faster. It provides the necessary support for the habitat of all life on land-including diversity in the soil itself (in some regions, just a handful of soil contains microorganisms that are more than the people on Earth). In short, soil plays an essential role not only in feeding humans but in supporting the living things that produce the oxygen we breathe and purifying the water we drink. In other words, soil keeps our planet habitable.

We, therefore, must stop considering ”soil“ a dirty word and remember that the food we eat and water we drink can be traced back to it. Businesses should adopt guidelines that ensure the long term health and productivity of soil. And local and national governments should provide policies that encourage soil protection.

Soil is one of the most important resources on our planet, and we have ignored it too long-at our own risk. The most important thing that can happen is a change in mind-set that recognizes soil is not dirt. It’s life beneath our feet.
