TOKYO—Lonely astronauts on the International Space Station (ISS) may soon be getting a robot friend from Japan.

    Japan's space agency is considering putting a talking humanoid(有人的特点的) robot on the ISS to watch the work while astronauts are asleep, monitor their health and stress levels and communicate to Earth through the micro­blogging site Twitter.

    Japan's space agency JAXA announced this week that it is looking at a plan to send a humanoid robot to the space station in 2013 that could communicate with the ground through Twitter—primarily feeding photos, rather than original ideas —and provide astronauts with “comfort and companionship”．

    Following up on US NASA's “Robonaut” R­2 program, which is set for launch on the Discovery shuttle next week, the Japanese robot would be part of a larger effort to create and refine robots that can be used by the elderly, JAXA said in a statement.

    Japan is one of the leading countries in robotics and has a rapidly aging society with one of the world's longest life expectancies.

    Improving robot communication capabilities could help elderly people on Earth by providing a nonintrusive(无干扰的) means of monitoring the robot owner's health and vital signs and sending information to emergency responders if there is an abnormality, JAXA said.

    “We are thinking in terms of a very human­like robot that would have facial expressions and be able to talk with the astronauts，” said JAXA's Satoshi Sano.

    The robot was being developed with the advertising and communications giant Dentsu Inc and a team at Tokyo University.

    The NASA project has a human­like head, hands and arms and uses the same tools as station crew members. The “Robonaut” called R­2 is intended to carry out maintenance tasks in the station's Destiny lab.

    NASA says it hopes that humanoid robots could one day stand in for astronauts during spacewalks or perform tasks too difficult or dangerous for humans.

    For now, the $2.5 million NASA robot is limited to activities within the lab.

    We get it: You're tired. You're busy. And your shoes are away over there. Excuses are OK sometimes, but not every day—and especially not today. So put on your sneakers, get up off the couch, and let us kick your excuses to the curb (路边).

    “I…dislike…panting !”

    Being really out of breath may mean you're trying too much too soon, which will kill your confidence. But you don't have to be huffing and puffing to get a workout. Being active doesn't have to mean high-intensity. It's just about moving.

    “I hate exercise.”

    It may seem unbearable, but you just have to get started. Exercise releases endorphins (your brain's own feel-good chemicals), which can be habit-forming. What' s the best exercise? The one you'll do regularly. So you may hate running. Don't run! Ride your bike or just dance. Even cleaning your room is active. As long as you're moving and getting your blood pumping, it counts. So get creative.

    “I don't have time.”

    You may not have lots of time to spare when you're busy with schoolwork, but we bet you can find 10 minutes. Bonus: An activity break will send oxygen to your brain, making you super-alert and more creative too. Famous thinkers like Aristotle and Steve Jobs liked “walking meetings," and you can follow in their footsteps by moving around while you brainstorm about a tough task or memorize your English vocabulary.

    “I never see results!”

    Even if you train with the help of a professional, you won't see results right away. But you will feel them almost immediately. Don't focus on how your body looks—focus on how you feel. Keep a journal of when you exercise (or don't) and how you feel that day: Stressed? Focused? Tired? When you start noticing the amazing effects of exercise, you'll have no excuses.

    I have a pair of pants. Tell me: How many different ways can I put a pair of pants to use?

    Now imagine you're Lady Gaga. Bill Gates. A scuba diver. An architect. You still have the pants. What other uses come to mind?

    What you just practiced—the conscious act of "wearing" another self—is an exercise that, according to psychiatrist Srini Pillay, MD, is essential to being creative.

    One problem about our understanding of creativity is that we tend to connect it to our concept of self: Either we're "creative" or we aren't, without much of a middle ground. "I'm just not a creative person!" a frustrated student might say in art class.

    Dr. Pillay, an assistant professor at Harvard University, has spent a good part of his career challenging these ideas. He believes that the key to unlocking your creative potential is to reject the old advice that urges you to "believe in yourself." In fact, you should do the opposite: Believe you are someone else.

    Dr. Pillay points to a 2016 study where the authors – educational psychologists Denis Dumas and Kevin Dunbar-divided their college-student subjects into three groups, instructing one group to think of themselves as "poets" and another to imagine they were "librarians" (the third group was the control). The researchers then presented all the participants with ten ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one.

    Those who were asked to imagine themselves as poets came up with the widest range of ideas, whereas those in the librarian group had the fewest. Meanwhile, the researchers found only small differences in students' creativity levels across academic majors. In fact, the physics majors pretending to be poets came up with more ideas than the art majors did.

    These results, write Dumas and Dunbar, suggest that creativity is not an individual trait but a "product of context and perspective." Everyone can be creative, as long as he or she feels like a creative person.

    Demand for the Chinese tech company's devices(设备) is red hot even though the country's overall market for smartphones is getting smaller Huawei's China sales rocketed more than 20% in the final quarter of 2018, and experts say that's partly due to the US govenment's global campaign against the company.

    "The latest tension between the US and China raised the patriotism(爱国主义) in Chinese consumers, said Jusy Hong, an analyst at research firm IHS Markit

    He pointed out that some Chinese companies encouraged employees to buy Huawei phones late last year. The moves were a gesture of support after the firm's chief financial officer was arrested in Canada in early December at the request of the United States.

    Huawei's booming sales show how major parts of its business continue to increase even as the United States tries to persuade other countries to shut Huawei products out of 5G wireless networks and pursues(追究) criminal charges against it. The company expects to overtake Samsung as the world's biggest smartphone maker by next year.

    Huawei sold 30 million phones in China in the last three months of 2018, nearly three times as many as Apple(AAPL), according to data published this week by research firms Canalys and IDC. Apple's sales plunged almost 20%.

    Huawei's success in China, the world's largest smartphone market, is more than about geopolitics(地缘政治). Chinese consumers love its flagship, high -end- phones because they have great cameras, cutting edge technology and cost less than the latest iPhones, according to analysts. And by offering a selection of cheaper phones, Huawei is able to target a bigger market.

    It also benefited from the troubles this year at ZTE (ZTCOF), a rival Chinese smartphone and telecommunications equipment maker. ZTE was banned by the US government from buying vital American parts for months last year.

On account of the government shutdown, many of the city's best attractions, such as the national museums, are closed. It may affect your social plans. That's especially true if you have out-of-town visitors coming to the District. Don't worry! For every closed museum, we've offered up a suitable substitute that is privately run, thus not subject to the shutdown. Here's where you can go instead.

Anacostia Community Museum and the National Museum of African American History and Culture

Alternatives: Banneker-Douglass Museum or Alexandria Black History Museum

The National Museum of African American History and Culture is one of the hottest draws on the National Mall, with free tickets taken weeks in advance. Its sister museum, the Anacostia Community (社区) Museum, takes a community-focused look at African American history. So does the Banneker- Douglass Museum in Annapolis, which traces (追溯) the African American experience in Maryland, and the Alexandria Black History Museum, where exhibitions honor local activists and explore the influence of slavery in the area. And unlike the African American Museum, neither requires you to plan ahead.

Hirschhorn Museum and Sculpture Garden

Alternative: Glenstone

Wandering through the galleries at Glenstone, you'll come across some of the biggest names in 20th century art — Jackson Pollock, Jean-Michel Basquiat and Robert Rauschenberg. Glenstone sits on a 230-acre estate (土地) that doubles as an outdoor sculpture garden. Free tickets for Glenstone are often reserved weeks in advance, but 72 free tickets are available every day for anyone who takes a Montgomery County Ride-On Bus from Rockville Metro Station to the museum.

National Museum of African Art

Alternative: The African Art Museum of Maryland

Masks, musical instruments and jewelry can be found in Fulton, where the African Art Museum of Maryland houses a collection of traditional and contemporary African artworks and objects. And the best part, for visitors on a budget? Admission is free.

What is the best part of a typical relaxing summer day? Nothing is better than sitting in an armchair with a beer and some chips in your hand, enjoying the great comfort.

The much-loved combination of beer and chips is being exploited for the first time to deal with climate change. Chips firm Walkers has adopted a technique it says will cut CO₂ emissions (排放) from its production process by 70%.

The technology will use CO₂ captured from beer processing in a brewery (啤酒厂), which is then mixed with potato waste and turned into fertilizer. It will then be spread on UK fields to feed the following year's potato crop. Creating fertilizer normally produces high CO₂ emissions, but the technology adopted by Walkers makes fertilizer without generating CO₂. So, the beer-and-chips combination performs a double function. It stops the emission of brewery CO₂ into the atmosphere — and it saves on the CO₂ normally generated by fertilizer production.

This Creative win-win solution was developed with an approval from the UK government by a 14-employee start-up called CCm. The fertilizer was experimented on potato seed beds this year, and next year Walkers will install CCm equipment at its Leicester factory to prepare for its 2022 crop.

A decision has not yet been made on which brewery Walkers will work with on this. The new technology adds to carbon-saving techniques already under way. The firm has installed an anaerobic digester (厌氧消化池), which feeds potato waste to bacteria to produce a useful gas. The gas is burned to make electricity for the chip-frying process — so this saves on burning gas or coal.

The new system will go a step further by taking away potato "cake" left after digestion — and mixing the brewery CO₂ into it to make an enriched fertilizer which will help put carbon back into the soil as well as encouraging plant growth.

It's an example of scientists finding ways to use CO₂ emissions which otherwise would increase the over-heating of the planet.
