Scientists have taken a major step toward the 3D-printing of parts of the human body. A new technique for bio-printing tissue allows scientists to create blood vessels. Jordan Miller, assistant professor of bio-engineering, explains why this development is so important. He says that this is the first step toward discovering how to print complex networks of blood vessels, which are necessary for supplying nutrients to tissue. The importance of this development was also highlighted by Miller's colleague, Kelly Stevens of the University of Washington. According to Stevens, this has solved a major problem. Now that scientists can print tissue that looks and even breathes more like the healthy tissue in our body, the hope is that it may also function like the healthy tissue. This is important because how well bio-printed tissue functions affects how successful it is in medical treatments. Scientists expect that bio-printing will become a part of mainstream medicine within the next 20 years.【缺少答案，请补充】
In November, mobile phone developers released a new feature that allows users to pass personal information to family members and friends in the event of the user's death. The feature and a number of similar services launched by tech companies one after another have started a heated discussion about arrangements for digital legacy. Digital legacy, the digital information that is available about someone following their death, is often shaped by interactions the person had and the information that they created before their death. This might include their social media profiles, online conversations, photos, videos, gaming profiles, and their website or blog. As digitalization becomes further integrated into our daily life, netizens are increasingly concerned about the proper treatment of their digital legacy. Young people, in particular, tend to make plans in advance and many draw up wills including digital assets. Despite the trend, challenges still exist in identifying the scope of digital legacy and protecting privacy. Relevant laws are expected to be introduced in the near future.【缺少答案，请补充】
The inventor of the World Wide Web, Tim Berners-Lee, questioned what it had become on the 30th anniversary of its creation. He said many people now felt unsure whether the web was "a force for good". In an open letter to mark the anniversary, he described the web as a "mirror of humanity" where "you will see good and bad". Noting privacy and safety were now under serious threat from the Internet, Berners-Lee expressed three main worries about it. The first worry is criminal behavior, like hacking and online harassment. The second is how social media spreads false information, especially fake news. The final one is about people's privacy. Berners-Lee also stressed the importance of fighting for a better and safer web and keeping it free for everyone to use. "If we give up on building a better web now, then the web will not have failed us. We will have failed the web," he wrote. "It's our journey from digital adolescence to a more mature and responsible future."【缺少答案，请补充】
Conversation 1 William: Hi Carolyn. Carolyn: Hi William. What are you doing? William: Well, I'm thinking about doing a digital detox. Carolyn: What do you mean by "doing a digital detox"? William: It means I'm going to take a break from all my digital devices and stay disconnected for a while. Carolyn: Wow! So, you're going to stop using your phone, laptop, and cut yourself from the Internet as well? William: Yes, and I'm going to do that for a whole week. Carolyn: Really? But why are you doing that? William: I think I'm using digital devices too much and that has started to affect my health. Being surrounded by technology and the Internet all the time stresses me out. Carolyn: That's too bad. But do you have to stop completely? I think the most important thing here is moderation. You just need to control how much you use digital devices. William: You're right, but I find moderation really difficult. A short detox may help

William: You're right, but I find moderation really difficult. A short detox may help me reset. Carolyn: That sounds even more difficult. I'm really curious to know how you will carry out your plan. What if someone calls you or sends you a message? William: Well, I will still answer phone calls. I just won't use any app or social media. I will not reply to messages, either. Carolyn: But people will expect you to answer if they send a message or email. William: If it's urgent, they will call me. People survived without phones before! Carolyn: That's a good point, but it's a very different world now. William: True, but I want to give it a go. Carolyn: OK. Good luck then! Remember to share your experiences with me.【缺少答案，请补充】

And, I really like the immersive display feature. Bob: I don't use my phone for games that much, so the display isn't a priority for me. But I'd love a better camera. The photos I take with my phone are of poor quality,【缺少答案，请补充】
Mobile app development is one of the fastest growing industries now. Statistics show that worldwide, there are about six billion smartphone users, and many of them have installed dozens of apps on their phones. According to research, there are three hot trends in the development of mobile apps. First, the Internet of Things, or IoT, is considered to be an important new technology in mobile app development. With IoT, people can monitor their devices from mobile phones and get operational data. IoT apps are now being developed for smart homes and smart areas, self-driving cars, health care, etc. Second, 5G technology has been around for some time now and has made its way into the development of mobile apps. It makes apps more user-friendly. Videos will start to replace images as a means to drive user engagement, VR - and AR - based features will become more common, and users will experience increased visual clarity thanks to the high - speed connection. It is expected that in just a few years' time, the customer experience with mobile apps will be completely different from now. The cloud is another technology that has much to offer to mobile app development. These days, with the help of the cloud, many security - related concerns in mobile app development have been solved. Thus, mobile app development becomes safer, more reliable, and faster. For example, it is now possible to develop powerful apps that run directly on the cloud, which requires minimal storage space on individual users' smartphone. Obviously, technology will never stop evolving, nor will the mobile app development industry.【缺少答案，请补充】

Experts believe that the next big change in agriculture will be digital farming. It is the use of technology to collect, store or analyze digital information for smarter farming. Farmers have always collected and assessed large amounts of data with each growing season: seed varieties, inputs applied, harvest, etc. Today, the rise of data science and digital technologies provides farmers with even more new data and new opportunities to improve operations and outcomes. It affects the entire process - from the purchase of seed, transportation, funding, farming, to sales. For digital farming, remote sensors and satellites are used to constantly collect millions of data points by monitoring plant health, soil conditions, temperature, etc. After the data is collected, AI tools can analyze it at high speeds, send the results to farmers, and help them make critical and practical decisions. The most important advantage of digital farming is the boost of food security and protection of natural resources. It also brings about improved labor and production. From a marketing perspective, the technology matches buyers with sellers, lowers the cost of trading, and allows more farmers to enter the market. The use of big data works best for large farms, but may become a threat to unskilled labor. Digital farming is an important development in modern agriculture. In the future, the technology will continue to enhance farming efficiency by monitoring each piece of land and determining the precise inputs needed for crops to thrive.【缺少答案，请补充】
A new wearable device called Moodbeam can let people know their mood. In the form of a wristband, Moodbeam was designed by a U.K. company to help medical staff monitor their mood. Wearers of the device can check their mood by logging in to their Moodbeam account, and information about their mood will be stored in the cloud. Moodbeam can also be used by employers to promote the employees' mental health and well-being. The original idea for the Moodbeam wristband came from a worried mother. She wanted to know how her daughter was feeling when she wasn't with her. The company's website says: "Moodbeam is built on the unfortunate truth that while how we feel is important to our well-being, it's hard to capture, tough to talk about, and often invisible." The device "allows for a better understanding of how we feel, creates more meaningful conversations with those we care about, and helps us lead a happier life".【缺少答案，请补充】

Host: Hello and welcome to Financial Updates! Today, we've invited Professor Li Rui, an expert in finance, to introduce digital RMB. Professor Li, could you please first introduce digital RMB briefly? Prof. Li: Sure. Digital RMB, also called e-CNY, is a digital form of China's legal currency RMB. It's a central bank digital currency that aims to replace some of the cash in circulation. Host: I see. How can we use it then? Through an app or something? Prof. Li: Well, it's pretty similar to an online payment transaction with third-party payment providers. You can just download the digital wallet on your mobile phone. Host: Sounds easy. But what's the difference between digital RMB and third-party payment providers? Prof. Li: You know, with third-party payment providers, people need to link their account with their bank card. But with digital RMB, the money is in our wallet. We don't need the bank to help us transfer. Also, unlike third-party payment providers, transactions using digital RMB can be done without the Internet. Host: That's very convenient. Will it be used as commonly as third-party payment providers? Prof. Li: Yes, in all situations where cash is used, digital RMB can also be used, such as payment between individuals and shopping in stores. Host: That's great! Now the last question: How will it affect people's life? Prof. Li: That's a good question. It will reduce the use of cash, as I just mentioned. It will make our life more convenient. And more importantly, it has good safety. People don't need to worry about bank card theft or cash loss. Host: Thank you, Professor Li, for all the information you shared with us. Prof. Li: My pleasure.【缺少答案，请补充】
