1 . In May this year, as part of our 150th anniversary, we asked readers aged between 18 and 25 to enter an essay competition. The task was to tell us, in no more than 1,000 words, what scientific advance they would most like to see in their lifetimes, and why it mattered to them.
The response was phenomenal: we received 661 entries. Some entrants hoped that science would make their lifetimes much longer than they can currently expect. Many looked forward to work that will end climate change. Others wanted to see advances in our understanding of human history, crop growth, space exploration, and medical technologies. The ideas were inspiring.
The winner is a compelling essay by Yasmin Ali, a PhD student at the University of Nottingham, UK. Ali submitted a piece on Beethoven, her brother’s hearing loss and the science which she hoped would one day cure it. It stood out to the judges as a reminder of why many scientists do research: to make the world better tomorrow than it is today.
All essays were judged by a group of Nature editors. The top ten submissions were then ranked by three members of a separate judging group: Magdalena Skipper, editor-in-chief of Nature; Faith Osier, a researcher; and Jess Wade, a physicist. All submissions were kept anonymous throughout the process.
We also selected two runners-up(非冠军的获奖者).Physicist Robert Schittko at Harvard University in Cambridge, Massachusetts, proposes that nuclear fusion(核聚变) could offer a solution to the climate crisis, in a piece that effortlessly mixes grand ambition with gentle humour. And chemist Matthew Zajac at the University of Chicago in Illinois wrote a powerful personal account of why he wants to see advances in the field of same-sex reproduction.
The results show that today’s young scientists have a wealth of ideas, talent and conviction that research can transform their world. We look forward to seeing what they do next.

2 . “The past is a different country; they do things differently there," L.P. Hartley wrote in one of his best-known novels, The Go-Between. To the British novelist, the past was irrelevant. And one of my Chinese students once told me "I have no interest in the past. I'm only interested in the present and the future." I have to disagree. The "past" is a very interesting country, and the more we know about it, the more we will be able to understand the present and thus, prepare ourselves for the future.
An ideal place, as I see it, that can allow us to look back on the past is the museum. I prefer to visit museums as if you are sitting in the same room with some of the greatest men in history. While no museums can claim to offer a complete picture of human history, the lessons we can learn from the events and wonders of the past are of great value.
Thanks to modern technology, museums are being transformed from places of looking and learning to spaces of participation and interaction. A large number of immersive (沉浸式) multi-media displays, which allow visitors to engage with its exhibits during their visit, play a big part at the Shanghai Natural History Museum.
The rise in technology has also made museums more accessible than ever. Since the outbreak of COVID-19, traditional museums have started to think outside of the box in order to create new ways for visitors to experience their collections online. It is definitely good news for those who are fascinated by museums but are struggling to actually go there. However, you shouldn't expect to get the same experience that an in-person visit would provide, at least, that is, for now.
International Museum Day is observed on May 18 every year. This is a quick reminder that you should always spare some time to visit museums and appreciate the "must-see 'em" things that are an important part of the cultural heritage of humankind.

3 . By mid-century there will likely be 9 billion people on the planet, using ever more resources and leading ever more technologically complex lives. What will our cities be like? How much will artificial intelligence (AI) advance? Will global warming cause disastrous changes, or will we be able to engineer our way out of the climate change issues? Recently, the magazine Big Think asked top minds from a variety of fields to weigh in on what the future holds 40 years from now. The result is as follows.
It's likely that by 2050 the majority of the people in the world will live in urban areas and will have a much higher average age than people today. Cities theorist Richard thinks urbanization will transform the education system of, making our economy less houses driven and removing the divisions between home and work.
And rapidly advancing technology will continue ever more rapidly. Cities of the future won't look like “some sort of science-fiction fantasy”, but it's likely that technological advances and information overlays (VR and AR) will greatly change how we live. Self- driving cars will make the roads safer and provide faster transports. A larger version of driverless cars-driverless trucks — may make long-distance drivers out of date.
Some long view predictions are completely dire. Environmentalist Bill says that if we don't make great progress in fighting global warming, it's likely we could see out-of- control rises in sea levels, huge crop shortfalls and wars over limited freshwater resources.
In terms of how we will eat, green markets founder and “real food" supporter Nina believes that there will be more small milk processing plants and more regional food operations and we'll be healthier as a result. New York Times writer Mark thinks that people will eat fewer processed foods and eat foods grown closer to where they live. And more people will be aware of the ethical responsibility" to grow foods.
1. What may happen by 2050 based on the magazine Big Think ?| A．Education will be driven by economy. | B．The majority of people will be taller. |
| C．AI will cause disastrous changes. | D．Most people will live in big cities. |
| A．It will make people live in science-fiction fantasy. |
| B．It will ensure safer transports due to faster cars. |

4 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?
These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.
Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.
More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.
Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).
How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?
1. What does paragraph 2 mainly tell us about mobile phones?| A．Their target users. | B．Their wide popularity. |
| C．Their major functions. | D．Their complex design. |
| A．Admit. | B．Argue. |
| C．Remember. | D．Remark. |
| A．They like smartphone games. | B．They enjoy guessing callers’ identity. |
| C．They keep using landline phones. | D．They are attached to their family. |
| A．It remains a family necessity. |
| B．It will fall out of use some day. |
| C．It may increase daily expenses. |
| D．It is as important as the gas light. |
5 . What picture do you have of the future? Will life in the future be better, worse or the same as now? What do you hope about the future?
Futurologists predict that life will probably be very different in 2050 in all the fields of activity, from entertainment to technology. First of all, it seems that TV channels will have disappeared by 2050. Instead, people will choose a program from a 'menu' and a computer will send the program directly to the television. By 2050, music, films, programs, newspapers and books will come to us by computer.
In what concerns the environment, water will have become one of our most serious problems. Demand for water will increase ten times between now and 2050 and there could be serious shortages. Some futurologists predict that water could be the cause of war if we don't act now.
In transport, cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed of the cars and there won't be any accidents. Today many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination.
In the domain of technology, robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots-they do not ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere — in factories, schools, offices, hospitals, shops and homes.
Last but not least, medicine technology will have conquered many diseases. Today scientists have discovered how to control genes. They have already produced clones of animals. By 2050, scientists will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. Scientists will be able to do these things-but should they?

6 . With over 4.1 billion people, or around 55 percent of the world’s population, living in urban areas, cities and towns worldwide are getting increasingly jammed. In addition to spending hours stuck in traffic, residents are also exposed to high air pollution levels caused by transportation emissions(排放). Now, Saudi Arabia hopes to overturn urban living with “The Line”—a futuristic city designed around nature, without cars, roads and crowded places!
The totally different city, announced on January 10, 2021, is the brainchild of Saudi Crown Prince(王储)Mohammed bin Salman(MBS).Located in Neom, a 10, 000-square-mile high-tech planned development on the Red Sea coast. The Line will be the base of MBS’s Saudi Vision 2030. The strategic plan aims to diversify Saudi Arabia’s oil-dependent economy into other fields, like tourism, and create exciting job opportunities for its citizens.
The 105-mile-long city, expected to cost between $100 billion and $200 billion, will be built along a straight line and comprise several self-sustaining communities. To ensure all services are within a short, five-minute walk, each community will feature a three-layer infrastructure(基础设施)．
There will be no cars or roads on the top “pedestrian layer”, so residents can freely walk and bike in the surrounding green spaces. The second “service layer”, will include all essential daily services, such as schools, medical clinics, leisure facilities, and grocery stores. The third “spine layer” will house ultra-high-speed transportation and autonomous vehicles transporting residents across communities in less than 20 minutes. The entire city will be powered with renewable clean energy sources such as solar and wind, and possibly even hydrogen．
If all goes according to the plan, construction of this groundbreaking, complex infrastructure project will start before the end of 2021. In addition to providing up to a million residents with a clean and stress-free living environment, the Line is expected to create 380, 000 new jobs, promote economic diversification, and contribute a shocking $48 billion to Saudi Arabia’s Gross Domestic Product(GDP)by 2030. More importantly, MBS believes it will provide governments worldwide a blueprint for how people and planet can co-exist in harmony.

8 . Sixty percent of Americans play video games daily, according to Techjury. In order to escape from the reality of quarantine (隔离), more people have turned to video games and VR (virtual reality) has become more popular than ever.
The world of VR isn't new to the gaming industry. It has been an ongoing concept for years, dating back to the 1800s. NASA popularized VR technology in 1989, bringing light to advancements that had never been seen before, and in 1991, SEGA introduced VR to gamers.
Gaming companies such as Oculus and HTC have redefined gaming by allowing players to involve themselves deeply in the world of VR through personal headsets. VR users are able to socialize through chat rooms, create 3D art and exercise through heart-pumping gameplay. Once a user puts on a headset, they are immediately transported into a virtual world. This allows the player to have a better experience compared to simply staring at a TV with a game controller.
Although VR has many positive aspects, using virtual reality too much can cause health problems among users. When using VR, it is common for people to lose spatial (空间的) awareness. Therefore, users are encouraged to play in an area that is clear of furniture and other objects causing potential danger. Eye strain can also be caused by using VR too much, so it is important to limit your time playing in virtual reality and take breaks in order to minimize the possibility of experiencing negative health effects.
How VR will develop in the future is unknown to us. However, new advancements for it are on the way. Teslasuit, a company specializing in VR equipment, is creating haptic (触觉的) suits for VR gameplay. These suits will allow users to feel aspects of VR while in game and will increase involvement, build 360-degree awareness and engage muscle memory. There are an endless number of possibilities that users can experience and create in VR, and the boundaries of the virtual world are limitless.

9 . Brain aneurysms (脑动脉瘤) affect about one in every 50 Americans and can lead to serious medical emergencies, including stroke, brain damage and death if they burst. Existing treatment options are limited and often invasive(扩散), and surgical outcomes can vary widely from person to person.
Researchers at Lawrence Livermore National Laboratory (LLNL) have become the first team to produce a living, bioprinted aneurysm outside of the human body, perform a medical procedure on it and observe it respond and heal as it would in an actual human brain.
“While there are a lot of promising treatment options, some still have a long way to go,” said Moya, the project’s principal investigator. One common treatment is “clipping”-attaching a metal clip to the base of the aneurysm to redirect blood flow away and keep it from bursting. The procedure is highly invasive, requiring surgeons to open up the skull and expose the brain. A more common and less invasive treatment is the metal coiling (缠绕) approach. The downside to “coiling” is that success is highly dependent on a variety of factors, including the geometry of the patient’s blood vessels, which differ from one person to the next, researchers said.
Animal models aren't necessarily the best way to try out these options, as they lack direct observation of treatment effects and have uncontrollable aneurysm geometries. Unlike animal models, LLNL’s platform allows scientists to directly measure the liquid.
To take some of the guesswork out of aneurysm treatments, Hynes, the original principal investigator, realized researchers would need a way to validate more predictive 3D models that take patient geometry into account by bioprinting with human cells.
By combining the 3D-printed platform with computational models, researchers said they've developed a potential tool for surgeons to pre-select the best coil types, and perform “testruns” of procedures before attempting them on the human patient “What’s exciting is that this platform copies the actual blood vessels and also is strong enough to handle a coiling procedure. This makes it ideal to be used as a training platform for surgeons.” Moya said.
In addition to a testbed for surgical training, researchers said the platform has potential for improving the understanding of basic biology and the post-surgery healing response. While early results are promising, the researchers cautioned there's a long way to go before the platform sees application in the clinical environment.

10 . In the past few decades, great progress has been made in the field of space exploration, which has enabled mankind to have a deeper understanding of the Solar System, our place in it and in the universe. “We sent probes(探测器) to every planet in the Solar System. This is by far the best one,” said Clayton, vice president of Blue Origin. “Let's focus right now on protecting the Earth environment, and then we'll go from there. Space science and technology should be people-centric and application-centric, and focus on improving human life. We need to have a strong footing on the Earth, learn to solve the day-to-day problems of the society.”
“Space technology can help achieve the 17 sustainable development goals to be achieved by 2030 set by the United Nations. Satellite monitoring can really help with agriculture. ” said Victoria, CEO of a company working on sustainable development, “Through Global Navigation Satellite System, animals' movement information recorded on self-recharging devices can be transmitted to the company server. Farmers can be alerted in real time if anomalies(异常现象）are detected. We can use it to ensure the traceability of the entire meat chain. As a result, it enables consumers to know that the beef they are eating does not come from protected areas or the cattle don't contribute to deforestation. ”
As early as 2007, Michael Griffin, former Administrator of NASA, put forward the concept of the “space economy” in a speech. He is very optimistic about the market prospect of commercial space and said, “According to the latest data, the global space industry could reach $1 trillion in 2040, up from $ 378 billion currently. I believe more business models and space activities will be created in the future to achieve the economic scale of $1 trillion. ”
As an entrepreneur(创业者）herself, Victoria thinks the thriving space market will bring countless opportunities for entrepreneurs. She mentioned future settlements on Mars or on the Moon. “If we are going to develop a new society outside the Earth, we will need all types of applications and all types of startups. But coming back to the Earth, there are so many problems that need to be solved, and space technology can really help with that.”
