2 . For years, planet-hunters have been searching for a planet other than Earth that can support life. They may have found one.
The planet is the sixth found orbiting a star called Gliese 581. Steven Vogt, one of the scientists involved, expects the new planet to have water. On Earth, when we find water, we find life.
A planet that can support life has to be just the right size for its system and just the right distance from its star. Some planets orbit so close to their stars that they’re much too hot for liquid water—or for life as we know it.
But a right-sized planet that's neither too close nor too far might be just right for water. Gliese 581 is probably just right. It is about three times as huge as Earth.
The new planet is 20 light years away, which is as far as 250 million trips to the Moon and back.
Gliese 581 is an exciting discovery—and astronomers are likely to find more soon, thanks to new, powerful telescopes specifically designed to look for planets.
| A．We can’t travel at the speed of light. |
| B．It’s pretty hard to imagine that water wouldn't be there. |
| C．Human beings won’t be visiting this planet any time soon. |
| D．So scientists looking for life on other planets look for water first. |
| E．It orbits its star so closely that it goes all the way around in only 37 days. |
| F．Astronomers will probably find more potential life-supporting planets soon. |
| G．Other planets keep their distance from the stars—where they’re too cold to have water or life. |
3 . 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.

4 . 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.
