In many countries, schools have long summer holidays, with shorter holidays in between. However, a new report suggests shortening school holidays to stop children forgetting what they have learnt during the long summer break. Instead of three school terms, it says, there should be five eight-week terms. And there should be just four weeks off in the summer, with a two-week break between the other terms.

    Sonia Montero has two children at primary school and works full-time. She supports the idea. “The kids,” she says, “have much longer holidays than me and I can't afford to take several weeks off work, so I need someone to take care of them. But nobody wants the work in the summer months — they all have holidays of their own.”

    Not surprisingly, some young people disagree. Student Jason Panos says “It's a stupid idea. I would hate staying at school in the summer. It's unfair, too. The people who suggest this had long school holidays when they were young, but now they want to stop us enjoying the summer. The kids in Spain and America have much longer holidays than here, but they don't forget everything they've learnt in a few months.”

    Nadia Salib agrees. “Sure,” she says, “the first week at school after the summer is never easy, but you soon get back into it. The real problem round here is that kids get bored after so many weeks out of school, and then some of them start causing trouble. But the answer is to give them something to do, not make everyone stay in school longer.”

    Open work spaces definitely have their benefits，but they come with the drawback of offering employees little to no control over visual distractions(干扰)．With so many people around and so much going on，some of us can easily get disturbed by this information overload and lose focus in what's really important．That's where the Focus Cap comes into play．

    “As we are still cavemen or mammals kept in an unnatural environment，I believe that only by reclaiming(收回)the normal，stress-free human state through simple tools and techniques can we finally release our actual creative potential and create our meaningful work for a brighter future，”says German designer Hannes Greblin，inventor of the Focus Cap．

    After looking at other products designed at minimizing visual distractions，Greblin decided that most of them were either too expensive or too uncomfortable to become mainstream，so he decided to go with something much simpler —a simple cap with a retractable visor(可伸缩的帽沿)．

    Greblin's Focus Cap is really straightforward．You just wear it like a regular cap'with the sides of the visor retracted，and just collapse the sides whenever you need to focus on what's ahead of you．Whether you're trying to focus on a task in an open work office．Trying to study at university，or practicing yoga in a park and trying to ignore stares from strangers，the Focus Cap can help．

    To be honest，this whole project sounds like a joke，but the Focus Cap does have its own website where people interested in this unusual accessory can actually sign up for updates on when it will go on sale．Greblin claims it will cost 30 euros($37)plus shipping．

    Rain beat against the window, matching my mood. I should have known that my new job at the hospital was too good to be true. Throughout the day, rumors (传言) warned that the newest employee from each department would be laid off. I was the newest one in the training department.

    My boss appeared. “You probably know we're cutting back,” he said. “Administration wants us to offer outplacement classes to help those employees find other jobs, showing them how to act in an interview, for example.” “Fine,” I answered unwillingly, not knowing what else to say.

    I decided to go home early that day. In the hall, I met the lady who brought us cookies every Friday. She was a little woman with gray hair. Only her head and the top of her green apron were visible over the cart (小车) loaded with cleaning supplies. At least she had a job!

    At the final meeting, laid-off workers formed a line at the door. A colleague whispered, “I can't believe our Cookie Lady is being laid off. We'll miss her as much as we'll miss her cookies.” When the colleague spoke to her in Spanish, I knew my classes would be useless for her and I realized how much better off was than this poor woman.

    I decided to do something for her. I wrote to a newspaper expressing how I felt about the unselfishness of the Cookie Lady who needed a job. A few days later, my article appeared in the newspaper and the Cookie Lady was allowed to stay in her position. On the same day, I received a letter, which seemed so unlikely that I read it twice. “An editor of a local magazine likes your piece and wants you to call her next time you're looking for work …”

    As free as they make us, mobile phones still need to stay close to a power source. Soon that may change with "green" power.

    Three Chilean students got the idea for a plant-powered device(装置) to charge their cellphones, while sitting in their school's outdoor courtyard during a break from exams, with dead mobile phones. Then, one of them had an "aha" moment.

    “It occurred to Camila to say about plants,” said inventor Evelyn Aravena. “'Why don't you have a socket, if there are so many plants? 'After that, we thought, 'why don't they have a charging outlet? Because there are so many plants and living things that have the potential to produce energy, why not?'”

    Their invention—a small biological circuit called E-Kaia—uses the energy plants to produce during photosynthesis(光合作用). A plant uses only a small part of that energy and the rest goes into the soil, and that's where the E-Kaia collects it. The device plugs into the ground and then into your phone.

    "It's the most amazing project I've ever seen in my life, plain and simple. They brought this original model, and it worked — and that's when it all changed, at least from my personal point of view and I began to support them." said Mauricio Cifuentes.

    The device solved two problems for the engineering students — they needed an idea for a class project, and an outlet to plug in their phones.

    "Looking for a place to charge the notebook, which had no power, and the mobile phones, we weren't able to find anything because all the other students were in the same state of madness trying to find a place to charge their devices," said Aravena.

    But plants are everywhere, and the bio－circuit makes the best of their excess(过多的) power.

    The E-Kaia doesn't carry much charge but it's powerful enough to completely recharge a mobile phone in less than two hours.

    The student inventors have applied for patents on their technology, and expect the E-Kaia to go on sale in December 2016.

    UK-based swimming pool manufacturer (制造商) Compass Pools has announced plans for the world's first 360-degree infinity (无限) pool. Titled Infinity London, the pool would contain 600,000 liters of water, and would sit at the top of a 55-story hotel.

    According to Compass Pools' plan, the pool would feature transparent (透明的) walls and floor, offering views across London's skyline and down into the hotel below. These walls would be made of cast acrylic, a material chosen to make sure that the material is completely clear.

    The main problem with designing the pool was how to make sure entry or exit from the pool without affecting the view. Speaking about this design, Compass Pools' technical director and designer Alex Kemsley explained，"Normally a simple ladder would suffice, but we didn't want stairs on the outside of the building or in the pool as it would spoil the view – and obviously you don't want 600,000 litres of water running down through the building either. The solution is based on the door of a submarine, coupled with a rotating spiral (螺旋的) staircase which rises from the pool floor when someone wants to get in or out."

    Take a look at early models of how the pool might look in the gallery above. At present, no contract has been made but building work could begin as early as 2020.

The coronavirus in China right now has really turned things upside down for a lot of people, but not even it can come between a marathon runner and his training.

Like many of his countrymen, Pan Shancu, an amateur marathon runner from Hangzhou, in the eastern Chinese province of Zhejiang, is trapped in his apartment because of the COVID-19，but he didn't let that small detail stop him from keeping in shape for his next race, whenever it may be. He has been using the small space in his apartment as a training track, jogging around two tables and the short length of a small hallway, and recently posted on social media.

"I could not bear siting around anymore," Pan wrote. "Let's run laps in the room! Yes, one lap is about eight meters (26 feet) and I ran 50 kilometers (31 miles), I did it in 4:48:44. I am sweating all over, feeling great!"

The runner, who has a marathon best of two hours and 59 minutes, also wrote that he considers his neighbors while jogging, trying to step as lightly as possible on the floor as not to disturb them. He completed 6, 250 circuits in one of his rooms in four hours, 48 minutes and 44 seconds, and his neighbors have yet to complain.

Pan Shancu's achievement spread rapidly like virus this week, with people praising his training spirit, and saying to adopting similar strategies to stay in shape.

"I start in the kitchen, go through the living room, turn into my daughter's room, the less than 20m-long racecourse has beautiful scenery and on my left, my husband's snoring is cheering me on," one commented on Pan's post. "This is a silent battle. My husband's opinion is that I have psychological issues.
