1 . In the magnificent range of mountains of northern California, 42 radio telescopes point towards the stars, scanning for signs of life. The Search for Extraterrestrial Intelligence （SETI） Institute has been listening for a signal here since it was founded in 1984. Jill Tarter, its co — founder, says the programmed aim is not just to communicate with remote civilisations. It is also to remind human beings of its own modest, fragile （脆弱的）place in the universe. Thus, for the first time, SETI is cocking its ear towards Earth to look for a signal that can be sent into space to represent the species.

Felipe Perez Santiago, a Mexican musician and composer, has an idea of what might work.Since songs, like the human voices, are common to all languages and nations, he and Ms. Tarter have designed the “Earthling Project”-a call to people everywhere to upload extracts （精华）of song that he plans to melt into a collective human chorus. An initial composition will be launched into space this summer, recorded on a virtually indestructible disk. Future plans and dreams include an eventual landing on Mars.

Human music has been sent to the heavens in 1977. Distant beings can in theory already enjoy Peruvian panpipes, a Navajo chant, Bach, Beethoven and more. But no previous offering, and perhaps no composition undertaken anywhere, has tried to encompass the entire diversity of human song.

Mr. Santiago says he is thrilled about bringing together contributors from around the globe. Unlike other recordings sent into space, says Mr. Santiago, “Everyone's invited. You don't have to be one of the main composers of our history like Beethoven, just someone singing in their shower.” Download the “Earthling Project" app, sing up to three songs of 30 seconds each, and your voice will be sent into the sky.

2 . The AI project intends to use artificial intelligence to create an innovative (创新的) theatrical performance, which is expected to premiere (首演) early next year. Head of the research team Rudolf Rosa said: “The main idea behind our study came from Tomáš Studeník, an innovator who noticed the centenary of the play ‘RUR’ is approaching. “This was a key moment for robotics, as the idea of a robot, including the word ‘robot’ itself, was invented by Karel Capek and his brother Josef wrote this play.

“Tomáš believed this should be properly celebrated and formulated the idea of turning the story around: 100 years ago, a man wrote a play about robots; what if today, robots wrote a theatre play about men?”

While there are now numerous papers focusing on machine-produced art, including some where computational techniques were used to produce dialogues or story ideas for plays, the automatic generation of an entire theatrical performance is an extremely complex task never-before attempted.

Rosa’s team decided to split the production of their play into several sub-parts. Although other research teams have used this approach to generate dialogues, few have attempted to produce an entire play. Dr Rosa said: “Thanks to the approaching anniversary, our main target is clear and fixed: by January 2021, we need to have a play ready for premiere. As it will be performed by a professional theatre group, we need to have the script ready in September, so that there is enough time for rehearsals (彩排).”

The researchers started experimenting with pre-trained language model called GPT-2. Once adequately trained, GPT-2 is able to complete unfinished texts using similar language and covering related themes. For example, if GPT-2 is fed the first paragraph of a news article, the model will try to continue to write a few additional paragraphs on the same topic, using the existing text for inspiration, while generating sentences about new concepts.

3 . Procrastinators (拖延症患者)，take note: If you’ve tried building self-control and you’re still putting things off, maybe you need to try something different. One new approach: Check your mood.

Often, procrastinators attempt to avoid the anxiety or worry aroused by a tough task with activities aimed at repairing their mood, such as checking Facebook or taking a nap. But the pattern, which researchers call “giving in to feel good,” makes procrastinators feel worse later, when they face the consequences of missing a deadline or making a last-minute effort, says Timothy Pychyl, an associate professor of psychology at Carleton University.

Increasingly, psychologists and time-management consultants are focusing on a new strategy: helping procrastinators see how attempts at mood repair are destroying their efforts and learn to control their emotions in more productive ways.

The new approach is based on several studies in the past two years showing that negative emotions can damage attempts at self-control. It fills a gap among established time-management methods, which stress behavioral changes such as adopting a new organizing system or doing exercises to build willpower.

Researchers have come up with a playbook of strategies to help procrastinators turn mood repair to their advantage. Some are tried-and-true classics: Dr. Pychyl advises procrastinators to just get started, and make the doorstep for getting started quite low. “Procrastinators are more likely to put the technique to use when they understand how mood repair works,” says Dr. Pychyl, author of a 2013 book, “Solving the Procrastination Puzzle.” He adds,“A real motive power comes from doing what we intend to do—the things that are important to us.”

He also advises procrastinators to practice “time travel”—projecting themselves into the future to imagine the good feelings they will have after finishing a task, or the bad ones they will have if they don^’t. This cures procrastinators’ tendency to get so stuck in present anxieties and worries that they fail to think about the future.

Another mood-repair strategy, self-forgiveness, is aimed at dismissing the self-blame. University freshmen who forgave themselves for procrastinating on studying for the first exam in a course procrastinated less on the next exam, according to a recent study led by Michael Wohl, an associate professor of psychology at Carleton.

Thomas Flint learned about the technique by reading research on self-control, including studies by Dr. Sirois and Dr. Pychyl. He put it to use after his family moved recently to a new house. Instead of beating himself up for failing to unpack all the boxes gathered in his garage right away, Mr. Flint decided to forgive himself and start with a single step. I’d say, "OK, I’m going to take an hour, with a goal of getting the TV set up, and that's it, he says; then he watched a TV show as a reward. Allowing himself to do the task in stages, he says, is “a victory.”

4 . Don’t teenagers hate being treated like children? Shouldn’t we accept that they are growing up? Yes, of course, they are growing up and may want to change things about their habits or activities, but parents trying to be “supportive” and encourage these changes often do more harm than good.

For example, you and the rest of your family are heading up to the mall for hours. Your teenage daughter Laura has shown resistance to being seen with you in public recently, so you decide not to persuade her to come with you. This seems like a very respectful thing to do that takes into account her feelings and opinions, but when you return she is upset. What went wrong? Well, many things could have gone wrong while you were away. She could have been caught up in friend drama, boy drama, or any other kinds of drama. Or she could be feeling hurt. Maybe she really didn’t want to go to the mall with you, but maybe you should have at least talked with her about it. Even knowing that you wanted to spend time around her probably would have felt good.

Some people say that this is an unreasonable expectation for parents to be “enabling” their kids to demand constant attention and validation (确认). I say, spending 30 extra seconds to make sure your children know you care about them is only “enabling” them to have a part of the self-worth they are so lacking at this time in their lives.

Expecting them to be removed and emotionally distant from you only re-enforces the idea that they should be. Always give them the choice to be an independent teen or your baby girl. When they need a break from the high school soap opera, you will both be glad you didn’t close that door.

5 . Last year, 138,000 San Francisco residents used Airbnb, a popular app designed to connect home renters and travelers. It’s a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, as San Francisco voters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.

The company fiercely opposed the measure, Proposition F, with a nearly $10 million advertising campaign. It also contacted its San Franciscan users with messages urging them to vote against Proposition F.

Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on road trips and longer stays in cities, and it often has more competitive pricing than hotels. It’s a textbook example of the “sharing economy”, but not everyone is a fan.

The app has had unintended consequences in San Francisco. As the San Francisco Chronicle reported last year, a significant amount of renting on Airbnb is not in line with the company’s image: middle-class families putting up a spare room to help make ends meet. Some users have taken advantage of the service, using it to turn their multiple properties into vacation rentals or even full-time rentals. Backers of Proposition F argued that this trend takes spaces off the conventional, better-regulated housing market and contributes to rising costs.

“The fact is, widespread abuse of short-term rentals is taking much needed housing off the market and harming our neighborhoods,” said ShareBetter SF, a group that supported Proposition F. Hotel unions have protested the company’s practices in San Francisco and other cities, saying that it creates an illegal hotel system.

San Francisco is in the middle of a long-term, deeply rooted housing crisis that has seen the cost of living explode. Actually, explode is a generous term. The average monthly rent for an apartment is around $4, 000. Located on a narrow outcropping of land overlooking the bay, San Francisco simply doesn’t have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking to Silicon Valley.

As the Los Angeles Times reported, some San Francisco residents supported the measure simply because it seemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runs much deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city’s existing problems.
