With brown curly hair and a pair of glasses, 19-year-oldNicholas Allegra from New York state, US, looks like a real-life Harry Potter.However, rather than waving a wand, Nicholas is a "wizard " at"jailbreaking ". This is probably why he ended up with an intern­shipat Apple, a job many of his fellow Brown University students dream of.

Jailbreaking is the process of removing the limitations set byApple on devices with the iOS oper­ating system. These devices include theiPhone, iPod Touch, and iPad. It allows users to gain full access to theoperating system and download additional materials that are unavailable through the official Apple App Store.However, it is estimated that Apple loses $100 million (640million yuan) fromjailbreaking each year.

Nicholas, with a famous nickname "Comex", is theteenage hacker behind the jail-breaking site JailbreakMe. com. The site tellsusers how to unlock their iPhones using software that is not approved by Apple.The jailbreaking software he made has been downloaded millions of times byusers around the world.

Then Forbes magazine suggested in an article that Apple's securityteam might need him as a new intern. It seems that they do. Little more than aday after Steve jobs stepped down as CEO, Apple welcomed Nicholas Allegra.Nicholas wrote on his Twitter on August 26 that " It's been really, reallyfun, but it's also been a while and I've been getting bored. So, the week afternext I will be starting an internship with Apple.

Apple is not the only company embracing the skills ofhackers. Facebook recently hired iPhone jailbreaker George "Geohot"Hotz as a full-time employee.

However, there are still hot debates about whether employinghackers is a wise solution. The word "hacker" has always had a doublemeaning. In the press, "hacker" means someone who breaks intocomputers. They steal from people's bank ac­counts, download sensitiveinformation and attack legal websites. Among computer lovers, it means a coolpro­grammer who can make a computer do whatever he wants.

Hiring a hacker does have its advantages. A talented hacker isprobably quite capable of finding problems and suggesting corrections. On theother hand, because of a hacker's former behavior, many people doubt theirmorals .Can the company trust them with its valuable assets ? And can someonewho is so used to working alone in the dark fit into a new role within acompany?

One thing is for sure- Comex isn't the first member of thehacker community to land the job of his dreams. It's likely that he won't bethe last.

    I had been following the yellowish-green markers for a “popular and easy” three-mile out-and-back hike. Immediately after the trailhead(山道的起点), the trail became very rocky and steep. But having read information about the hike, I knew within five minutes, I was supposed to reach the hike's first overlook.

    However, the overlook never arrived. Instead, I found myself lost in the woods. Pulling out my cellphone, I saw it read “no service”. I checked the last text message I'd sent to my mom. It read, “Conference ended…going for a small hike before my flight home this afternoon.” I put my phone away and kept moving and yelling, “Help! Is anybody out there?” Every so often, I'd stop to listen, but I never heard a reply.

    I got out my phone again. The battery was running out fast as it searched for a signal. I struggled to find a place where I could get service. When I did, I called my mom. It went through! In a shaky voice, I said, “Mom?” And then the call dropped. More than 1,500 miles away, my mom instantly knew something was wrong. She called the Denver Police Department and was directed to the US Forest Service.

    This was how I was introduced to John, an operator from the US Forest Service. Following John's instruction on the phone, I finally escaped from the woods. I breathed a sigh of relief. Then my phone rang, and it was John, making sure I was still going in the right direction. “By the way,” he said, “we've had your mother on hold this whole time. We know once you get down the mountain, you will absolutely want to give her a call.”

    What Theresa Loe is doing proves that a large farm isn't a prerequisite for a modern grow-your-own lifestyle. On a mere 1/10 of an acre in Los Angeles, Loe and her family grow, can(装罐)and preserve much of the food they consume.

    Loe is a master food preserver, gardener and canning expert. She also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control what's on their plate.

Loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “I got into cooking my own food and started growing my own herbs (香草) and foods for that fresh flavor,” she said. Engineer by day, Loe learned cooking at night school. She ultimately purchased a small piece of land with her husband and began growing their own foods.

     “I teach people how to live farm-fresh without a farm,” Loe said. Through her website Loe emphasizes that “anybody can do this anywhere.” Got an apartment with a balcony （阳台）? Plant some herbs. A window? Perfect spot for growing. Start with herbs, she recommends, because “they're very forgiving.” Just a little of the herbs “can take your regular cooking to a whole new level,” she added. “I think it's a great place to start.” “Then? Try growing something from a seed, she said, like a tomato or some tea.”

    Canning is a natural extension of the planting she does. With every planted food. Loe noted, there's a moment when it's bursting with its absolute peak flavor. “I try and keep it in a time capsule in a canning jar,” Loe said. “Canning for me is about knowing what's in your food, knowing where it comes from.”

    In addition to being more in touch with the food she's eating, another joy comes from passing this knowledge and this desire for good food to her children: “Influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture,” she said, “that if we don't take care of the earth, no one will.”

    The more interested you are in a topic, the more likely you may be to form “false memories” about the events related to that topic.

    “Most people are pretty confident about their own memory for some events, but new research shows that false memory is a lot more frequent than many people realize. In terms of daily life, the key point here may be to understand that someone who remembers an event differently from yours isn't necessarily lying—someone's memory may be faulty, or it might be you,” said study co-author Ciara Greene, a psychologist at the university College Dublin.

    In the study, the researchers asked 489 people to read four news stories about events that were related to the topics they ranked as the most interesting, and four stories about events related to the topics they rated as the least interesting. In each case, three of these events really did occur, but the fourth one was made up.

    It turned out that people tended to remember the stories of the topics they said they were more interested in compared with the topics they were not interested in. However, the participants also tended to store more false memories related to the topics they were interested in compared with the topics they were not interested in, the researchers found.

    The more people know about a topic, the more memories related to this topic they have stored in their brains, the researchers said. Therefore, when a person meets new information on this topic, that information may find traces of similar memories that have already stored in the brain, Greene said.

    “This can result in a sense of familiarity or recognition of the new material, leading to the conviction (确信) that the information has been met before and is in fact an existing memory,” Greene said. In other words, this new material or information may “feel” familiar and therefore the person may believe it must be true, he said.

    Learning more about how false memories work may help protect against the harmful results of them, such as when eyewitness accounts(证言) of crimes are faulty.

    American college students are becoming more adventuresome as they study abroad, showing less interests in English-speaking destinations such as Great Britain and Australia and more in such countries as China, India, Argentina and Brazil.

    Britain remained the most popular study destination in 2005, according to annual figures from the Institute of International Education, followed by Italy, Spain and France. But the number of American students studying in Britain and Australia descended a little, even as the number of American students abroad rose by 8%. The growth came in non-English speaking European countries and in Asia. China is now the eighth most popular destination for American students, attracting nearly 6,400 in 2005, up 35% from the number of the year before. Argentina and India saw increases of more than 50%.

    Allan Goodman, president of the Institute of International Education, said that a range of factors contributed to the trend, from growing awareness of globalization after the terrorist attacks on September 11, 2001, to programs such as former President Bush's National Security Language Initiative, which trains soldiers, intelligence officers and diplomats in foreign languages. “What Americans are doing is waking up and discovering there's a world out there,” he said.

    Other figures showed the flow of students in the opposite direction, from foreign countries into American universities. The institute found that international enrollment (入学) in American higher education remained steady at about 565,000. The figures are of keen interest to universities, which depend on foreign students for teaching and research help, and to policy-makers, who consider it important, as future foreign leaders may be familiar with the United States. The year of 2005 saw big increases in students from South Korea, Mexico and Taiwan of China. India sends the most students and China is No.2. Other countries that show large percentage increases in the number of students sent to the US include Nepal and Vietnam, while Japan, Turkey and Malaysia saw declines. About 58% of international students in the US come from Asia.

    At the age of seven, while his friends were spending their allowances on candy and toys, Jose Adolfo Quisocola, from Peru, came up with the creative idea of an eco-bank, which allows kids of all ages to become economically independent and financially wise while also helping the environment.

    Established in 2012, The Bartselana Student Bank is the world's first cooperative bank for kids. Whoever wants to join has to bring in at least 5 kilograms(11 pounds) of solid waste(paper or plastic) and establish a savings goal. Once accepted, all bank “partners” are required to deposit at least one additional kilogram(2.2 pounds) of recyclables on a monthly basis and obey other requirements, such as attending financial education and environmental management workshops. The waste accumulated is sold to local recycling companies, who, thanks to some clever negotiation by Jose, pay a higher-than-market rate for everything brought in by Bartselana Student Bank members. The funds received are placed in the individual's account where they collect until his／her savings goal is reached. The account holder can then withdraw his／her money, or choose to leave it and continue to grow for a bigger target.

    “At the beginning, my teachers thought I was crazy or that a child could not undertake this type of project, ” Jose recalls. “They did not understand that we are not the future of the country but its present. Luckily, I had the support of the school principal and an assistant in my classroom.”

    The youngster's persistence paid off. Today, the eco-bank, which now has the support of several local institutions, has ten educational centers and begins accepting applications from kids all across Peru. On November 20, 2018, the young boy was awarded the famous Children's Climate Prize (CCP). “Jose's eco-bank is a brilliant way of linking economy and climate impact, both in thought and practice. The potential impact is amazing,” a judge said.

    Hopefully, Jose's success will inspire more kids and adults to come up with new ideas that create value while helping the environment. As the boy says,” Together we can change the world…we just need an opportunity…”
