1 . For the past decade, one of the most linguistically (语言学地), diverse places in the world, square mile after square mile, has been my home: Queens, New York.

The soundtrack outside my door is extraordinary: On any given block, passing voices speak varieties of Polish, Ukrainian, Egyptian Arabic, Mexican Spanish, Puerto Rican Spanish, Dominican Spanish, and all the forms of New York City English they give rise to.

As a person who studies languages: I can usually distinguish them from one another, but understand only a part of what people are saying.

Users of Seke, a language from five villages in Nepal with 700 speakers, live a subway ride away. In certain stores, Albanians, Bosnians, Serbs, and Montenegrins all reunite, using the languages of the former Yugoslavia as if the country still existed. No group has a majority, or even 15. percent of the neighborhood, and most are at just 5 or 10 percent. English acts, for the most part, as a vital lingua franca (通用语). This’ last point is crucial, because a city can be a haven (避难所) for diversity but also an end point.

My neighborhood has its signature sound, but there are several dozen others that are just as diverse, each in a different way.

These are the places where the Endangered Language Alliance, the nonprofit I co-direct, has recorded New Yorkers speaking more than 100 languages that the survey and other data sets say don’t officially exist, and more than 700 in total.

That linguistic portrait makes clear that early-21st-century New York City is a last haven for endangered languages—ones that are being hounded out of existence elsewhere. And this deep linguistic diversity is among the least explored but possibly most important factors in New York’s history and makeup. New York’s soul can be found in the existence of these many, many languages, explaining New York’s particular capacity for tolerance and its ability to “make room” for others.

2 . Today, many people are turning to social media for their fitness routines, with TikTok, one of the most popular platforms. Indeed, its fitness category has some 300 billion views. But are the posted works, exercises and challenges really safe and effective?

While fitness influencers can encourage people to become more physically active, which is a positive, the quality and accuracy of their content is a concern, according to a 2023 review in Frontiers in Public Health.

“There are a lot of unsustainable and unrealistic workouts on TikTok, and even some dangerous advice,” said Jess Brown, a certified personal trainer in Westchester, New York. “What’s more, much of the fitness information on TikTok isn’t backed by science or posted by fitness professionals. The workouts are usually generalized to anyone, too, and don’t take into account your health, your family history, your flexibility, your range of motion—the list goes on,” said Monica Jones, a certified personal trainer in Washington, DC.

One of the more popular TikTok fitness trends involves developing your abdominal muscles. These challenges often show an influencer doing one exercise or series of movements that, if repeated daily for a week or two, is promised to result in a sexy six-pack. “No way,” Brown said. “We’ve proven again and again that spot reduction isn’t a thing.”

“Unfortunately, there will always be trends centered around getting fast results, because those grab people’s attention. But it’s important to look at your fitness and health as a lifelong journey, not something you can achieve within 10 to 90 days,” Jones said.

How can you separate quality workouts from dangerous ones? First, check the information of the posters. They should be certified fitness professionals who have experience working with people. You also want a coach who emphasizes improving strength and health, not one who focuses on body type. A quality influencer should encourage mental well-being, self-care and the importance of listening to your body in addition to physical fitness.

4 . While technology addicts teens to their devices, they are not helpless against the draw of it. Here are five ways educators can support their students’ digital well-being.

Explore design tricks companies use. The technology we use daily is designed to catch and hold our attention. Companies know what keeps our eyes on the screen. To help, teachers can unpack design tricks and explain how companies employ features like auto-play to get users to stay on their apps.     1    

Talk about how technology can increase feelings of anxiety. The decline in youth mental health is associated with an increase in social media use.     2     We can help our students by allowing them to consider the benefits of technology and then to think about changing the habits that aren’t serving their well-being.

    3     Social media can bring the feeling: “All my friends have better lives than me.” Plus, design features like “read receipts” can lead to teens knowing their messages have been seen and stressing about why friends haven’t yet replied. These are classic examples of thinking traps. Identifying them can help teens get rid of some negative thoughts.

Uncover the ways that AI can play a role in misinformation. AI is rapidly transforming the world. Recommendation algorithms (算法), which determine what we do and do not see on our feeds and in our search results, can have very real consequences.     4     By understanding how these technologies work, students can start to enjoy more benefits of technology.

Encourage families to have meaningful conversations with their child. Take the time to share with families the topics and resources you’re teaching in class.     5     Knowing we’re all in the same boat is crucial.

5 . 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.

8 . In this day and age we live in, our life is taken over by technology. We can’t imagine our life without it, and listening to stories that my mom tells about how she grew up without the Internet or cell phones sounds like a nightmare to me.

Though technology is wonderful and we are used to it and have no desire to be without it, it can be a good idea to sometimes just unplug (拔掉) from it all. Have you ever woken up in the morning just to see you have actually replied to a message to which the reply either doesn’t make sense or you can’t even remember that you did reply? This can be one of the signs that you are allowing technology to take over your life.

It can be very difficult to pull yourself away from the technology and you will feel you are going to be separated from the things or people around and miss a lot, but is it really so bad to at least get away from it at night and make sure you get a good night’s rest? You may feel you don’t need a lot of sleep, but at the end of the day you are making it difficult to concentrate the next day.

So let’s pack away the technology for a few hours at night—you only have to make a few small changes. Turn off your cell phone and switch off your computer at night when you go to bed. If you feel you will use your phone during the night, charge your phone in another room.

Make enough sleep a priority and feel and look good the next day. You may think it is a really silly idea to be without a cell phone or a computer during the night, but once you do it a few times and you get enough sleep and feel refreshed the following day, you will understand why it is a good idea and will try and unplug more times.

9 . The mushrooming video screens in buses, taxis and apartment halls in cities like Shanghai are taking away our already rare resource: a place for a moment of peace. Taking a nap or reading a book on buses is less pleasant now, as the LCD screens broadcast news, entertainment and advertisements at unbearable volumes.

You pay the bus fare simply to get a ride—undisturbed—but now you are exposed to this “added value”, whether you like it or not. If it’s a crowded bus, the noise is even more exasperating. More and more Chinese cities have joined Shanghai, regarded as the first to put video screens on buses, disturbing millions of passengers.

Some may like to watch programme aired on buses or in apartment halls. But those who don’t should be equally respected. Because of the bus screens, students cannot focus on reviewing their lessons or preparing for a test. People who like to read or reflect feel unsettled by the noise. Youngsters who like to listen to music on their iPods must increase the volume to fight against the competing audio. If you already feel stressed after a busy day, the bus video advertising certainly increase the tension of both your muscles and nervous system. Bus drivers are surely the worst victims because they have to bear it at least eight hours a day, non-stop.

A high public tolerance for noise pollution has helped bus video advertisers to expand their businesses. But opposition has already started to make its voice heard. Some people have already accused bus companies of breaking their contracts, since their obligation is only to deliver passengers to their destinations.

Shanghai, as a world-class city, should set an example for the country. It should first adopt world-class behavior in its massive public transportation system to return the public a peaceful place.
