A dog, it is said, is a man's best friend. Put a dog, a kid and a book together, and you have a struggling reader's best friend.

    The therapy dogs of R.E.A.D. – Reading Education Assistance Dogs – have been helping children improve their reading skills since 1999, when Intermountain Therapy Animals (ITA) began the program in Salt Lake City, Utah.

    Today, tens of thousands of R.E.A.D. teams – dogs and their owners – volunteer to spend time with youngsters in schools and libraries across the United States and around the world. The idea is that sharing a book with a nonjudgmental (不带评论的) partner encourages students' confidence and helps develop a love of reading.

    Izzy, a Havanese therapy dog, is a regular visitor to Public School 57 in East Harlem, New York. Students meet him in the library, pick out a book and sit down on the carpet. Izzy snuggles (依偎) up to them and gets ready to hear a story.

    “I love reading to Izzy because he listens to me, and he doesn't make fun of me when I make a mistake,” says third-grader Aelane Vasquez. The 9-year-old, whose parents are from Mexico, is one of 15 Latin-American students at the school who were selected for the program.

    “All the students that we work with in the R.E.A.D. program were behind reading levels at the beginning of the year,” Bridget McElroy, who teaches English as a Second Language, explained. “Now most of them have reached the average level, if not above it.” That's important, because achieving proficiency (熟练) in reading is vital for kids to succeed. Studies have shown that students who can't read at grade level by the end of third grade are four times less likely to graduate high school by the age of 19.

    The R.E.A.D. teams from New York Therapy Animals work with 175 kids at Public School 57 and nine other schools.

    McElroy said she sees a marked difference in Aelane and her classmates, and not just in study. “Not only do the kids have time to practice reading, what we are really seeing is that they are excited to read and practice even when Izzy is not here,” she said.

    You eat food and drink water, right? Skipping Rocks Lab is changing how you and your future generations will have water. Have you ever thought you could eat water? Think again, this is actually happening somewhere in the world.

    The group at Skipping Rocks Lab has made a water bottle you can eat. The product is called Ooho. Unlike plastic bottles, Oohos are neither tall nor hard. They look more like bubbles, or small, round, clear balls. They can hold liquid inside. People who drink Oohos can be surprised: the outside bursts in the mouth.

    Rodrigo Garcia Gonzalez is with Skipping Rocks Lab. He explains that the outside, or the membrane, of Ooho is made of seaweed, a plant that grows in the ocean. “It's a membrane made of seaweed that can contain water or any kind of liquid. It's made from an extract (汁) of the brown seaweed.”

    The Ooho membrane is tasteless, and you can eat it. The company says even if you throw away the membrane, it will break down in about four weeks. Gonzalez says the membrane is strong, and good for the environment.

Every year, billions of plastic water bottles are thrown away, polluting land and waterways around the world. The typical water bottle made of plastic can take hundreds of years to degrade.

    Lise Honsinger is also with Skipping Rocks Lab. “Most people just grab a bottle of water, hold it for five minutes, drink it, and throw it away. How can that then exist for 700 years? So, yeah, this is absolutely a solution to that. We are very purist: we don't want to see this packaged in plastic.”

    There are limits to the Ooho. It cannot be refilled. Each bottle is small. And Oohos do not store for more than a few days. The Skipping Rocks Lab is working on those issues. “We're still working on things like extending the shelf life, looking at different options in terms of thickness, if we want to make one that stands up more, or more flexible for marathons where people just want to eat it whole.”

    Right now, Skipping Rocks Lab can make only a few thousand Oohos a day. But it is developing new technology that could increase that number to hundreds of thousands.

    Bandhavgarh National Park in India is best known for its amazing setting, as well as having the highest concentration of tigers in India. In addition to tigers, there are also bears, deer, wolves, birds, etc.

    Location: In Madhya Pradesh state, almost 200 kilometers northeast of Jabalpur. The nearest village is Tala, which is the access point of the park.

    Opening Hours and Safari（打猎）Times

    Safaris operate twice a day, starting at dawn until late morning, and mid afternoon until sunset. The best time to visit the park is early in the morning or after 4 p.m. to spot the animals. the park is closed from July 1 to September 30 due to the monsoon season（季风季节）.

    Bandhavgarh Zone

    Bandhavgarh is divided into three main zones: Tala (the park's best zone, with the most tigers), Magdhi (the second best zone to see tigers), and Khitauli (scenic and less visited, although tiger sighting do occur there; particularly good for birding).

    Entry Fees and Charges for Jeep Safaris

    Bandhavgarh has become expensive to visit in recent years. Entry fees have increased since October 2014. When going on a safari, separate fees must be paid for park entry and jeep hire. Entry tickets are priced per vehicle (up to six people). For 2015-16, park entry tickets cost as follows:

    Tala Zone: 2,400 rupees for Indians, 4,800 rupees for foreigners. (Up to six people)

    Other Zones: 1,200 rupees for Indians, 2,400 rupees for foreigners. (Up to six people)

    Jeep Hire

    Expect to pay about 2,200 rupees to hire a jeep, in addition to the entry cost. This can be done at the park entrance. All hotels can arrange jeep hire and tours, but at a higher rate. It's much less trouble though. Besides, unlike many national parks in India, it's possible to take private vehicles into Bandhavgarh.

    Have you ever trained your brain? Now there are some new suggestions, such as eating dark chocolate and having cold meat for breakfast. You should also avoid watching soap operas, spending time with people who complain or follow fat-free diets, according to a new book on getting “brain-fit”.

    Many of the suggestions in Teach Yourself Training Your Brain are surprising. The book says to read out loud while holding a baby. Writers Terry Horne and Simon Wotton say their advice is from the latest research by experts around the world.

    “For years we have thought our brain capability is decided by our genes. But it's now clear that it depends on our lifestyle. What we eat and drink, how we learn at school and what type of feelings we have are all important,” said Horne.

    The book talks about the most up-to -date thinking in science about how diet, the environment, stress and other sides of modern life affect our brain capacity. It also offers advice and exercises. The book comes as more and more people are spending money on books, DVDs and computer games, which can improve their brain's capability.

    Horne believes that people need to make changes to their lifestyles to increase their brain capacity. Happiness, confidence and an optimistic nature help the brain, he added.

    “So mix with people who make you laugh, or share the same interests as you. And avoid people who complain,” said Horne. “People who are negative will make you sad, which means you won't achieve things.”

    Moksh Jawa, 16, a student at Washington High School in the US, has already become a legend(传奇) among students. “Why not?” might be his favorite question to ask.

    As a seventh-grader, he taught himself coding(编程) by studying on the Internet.

    As a high school freshman, he passed the AP Computer Science A exam with a 5, the highest score possible.

    As a sophomore (高中二年级学生), he developed his own online course and helped his classmates get through it because his high school didn't teach coding.

    Everything he did came from his own interest. His father sent him a link to Codeacademy, an online coding training program, in middle school. He learned a programming(编程) language all by himself after signing up to the website.

    “I just fell in love with computer science,”Jawa said. Along the way, he lit a fire of curiosity and passion among classmates to learn coding too.

    “All of my friends, especially the girls, were really, really afraid of computer science,” he said. But the subject and exam weren't things to be feared, he said, “Computer science is all about logic(逻辑), not about how smart you are. ”

    To make his knowledge available online, Jawa set about creating his own online course, with easy-to-follow lessons. He included quizzes and tests too.

    The course has so far attracted 3, 200 students across the US and in 120 countries and regions, including China, Ukraine and Algeria.  It shows, Jawa said, the huge need for coding lessons.

    When video lecturing, “I deliver it like I'm talking from one high school student to another,”Jawa said. “It's always great to make it as clear and fun as possible, and to try to keep my voice as energetic as possible. ”

    He also does that, when teaching members of the computer science club he founded at his high school.

    “His tutorials(辅导) were great, ”said Taj Shaik, the club's co-president, who took the whole course last year. “I'm definitely one of the early adopters(使用者) of Moksh. ”

    “He's pretty amazing, ”said Bob Moran, principal of Washington High School, who saw him lead the club. “He was just a fantastic teacher—clear, organized and entertaining. When a student got the right answer, he would throw him a candy. ”

    The number of snow geese arriving in the Arctic each spring to breed has risen over the past few decades. At first, wildlife biologists saw this as an environmental crisis, pointing to marshes（湿地） where plants were eaten by the hungry birds. In response, the federal government loosened restrictions on snow goose hunting.

    But how do the Inuit, in whose backyard this is taking place, view the situation? A recent plan is giving Inuit wildlife experts the opportunity to lend their knowledge to managing the species. The snow goose study, which is supported in part by Polar Knowledge Canada and led by the Kivalliq Wildlife Board (an Inuit organization that manages hunting, trapping and fishing in central Nunavut), asked the experts to share their generations of knowledge about snow geese and their views on what should be done.

    “The community had concerns about controlling the population,” says Ron, a community officer of the Kivalliq Inuit Association, “and Inuit snow goose knowledge had never been recorded. People wanted to pass on what they knew.” Inuit experts disagreed with that, considering it wasteful and unnecessary. They felt hunting more snow geese in an organized way, such as paying local hunters a minimal amount of money and distributing the birds to disadvantaged families or operating a limited commercial hunt by employing local people, would be appropriate.

    Inuit wildlife experts will plan to call on scientists this fall. They say they hope to search for a common way forward and that while there may be too many snow geese in some areas, it's not a crisis. Biologists now generally agree that there seem to be plenty of undamaged marshes available and newer research shows that some damaged areas can recover.

    “Now that we have recorded and documented Inuit knowledge of snow geese,” says Ron, “when facing the crisis other people will be able to use the information to help manage the species, which is fundamental to dealing with it effectively.”
