You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams (1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

    Rachel Carson (1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor (1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and, in 1981, the first woman to join the U.S. Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks (1913-2005)

    On December 1,1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was, was tired of giving in,” said Parks.

    I absolutely love Bark magazine! I love the “smiling” pages and the tips on every issue.

    Dog Fancy

    Don't waste your money on this magazine. 60-70 percent of it are advertisements, and the articles offer little useful information. It might be suitable for children, but not adults who are serious about educating themselves about dogs.

    Dog World

    Cover Price: $48.88           Price: $14.99 ($1.25 / issue)

    You save: $33.89 (69%)        Review: By one critic

    Dog World has many very interesting and thought-provoking (令人思考的) articles for people involved in dog showing, breeding(饲养), performance events, etc. However，over half of the magazine is devoted to breeder ads, which is boring. Still, as a whole, I recommend(推荐) it for the articles. Good articles, but tons of ads.

    Modern Dog

    Cover Price: $45.00             Price: $15.00 ($3.75 / issue)

    My new favorite magazine! Beautiful photos, smart and amusing articles, fashion, art, interviews with famous people… all with a dog focus！Cover models range from Paris Hilton and Tinkerbell to Virginia Madsen and her dogs. Thanks to Modern Dog I now know how to give a dog-friendly cocktail party and how to actually get my dog to come when she's called. Surely worth checking out.

    In box-office terms, Steven Spielberg is the most successful movie director in the world. Jaws, E.T. the Extra-Terrestrial, Indiana Jones, Schindler's List ... his movies are cinema classics.

Q: What were you afraid of when you were a child?

A: I was my own monster (怪物). My fancy was unbelievable, so I was afraid of everything. A chair could very quickly change into a mouse. I remember looking up at the sky when I was five. One of the clouds up there looked like a beautiful bird, then suddenly it was a tiger. I ran home crying.

Q: What did your parents feel about that?

A: For my parents my imagination was a real problem, so much so that they seriously considered having me examined by a doctor. After all I was always seeing things that didn't exist (存在) except in my head. My mother and father thought I had something wrong with my mind. I probably did — but it is the gateway to a great career!

Q: What do you consider your greatest career achievement so far?

A: The right to decide my own programs. That was always my only dream, telling my stories without anyone else interfering (干预). It was also why I built my own company.

Q: Which movie did you enjoy making most?

A: That was E.T. the Extra-Terrestrial, because it was the first time I realized I wanted to be a father. Three years later I had my first son.

Q: Do you make home movies?

A: Yes, I always have a video camera with me. At Christmas it's traditional for my family to see a movie about the family that lasts one hour. We all watch the film together and everyone gets a DVD of it.

    When introducing American universities, some of the first institutions to mention are the Ivy League schools. Originally, the Ivy League was an athletic conference made up of 8 private institutes of higher learning in northeastern United States. However, as time went on, these schools also became known for their excellence in academics besides athletics. Included in the Ivy League schools are Brown University, Columbia University, Cornell University, Dartmouth College, Princeton University, University of Pennsylvania, Yale University, and Harvard University. These 8 schools have been recognized as some of the best colleges and universities in the United States.

    Harvard University is a private institution located in Cambridge, Massachusetts. The university includes a number of graduate and professional schools, as well as a college for undergraduates. In 2012, Harvard ranked number one in US News' ranking of national universities again. Founded in 1636, Harvard is the oldest institute of higher education in the United States. It can be said that first there was Harvard, then the United States of America. Also, Harvard's library contains the oldest collection of books in the United States as well as the largest private collection in the world. Harvard has also been described by Forbes Magazine as one of the “billionaire universities” as of their recent list of 469 billionaires, 50 received a degree from Harvard.

    Harvard College (the institute for undergraduate students) is one of the most famous schools in the United States. It offers over 40 undergraduate fields of study, including astrophysics(天体物理学), mathematics, neurobiology(神经生物学), etc. And the financial aid program there is amazing. Even though the tuition is about $ 37,576, and there are other expenses throughout the year, about 70% of undergraduate students received financial aid. Out of those students, over 90% of them had their full need met. And the policies for international students are the same for U.S. citizens.

    Harvard College is very selective, as it only admits about 6% of their applicants. For admission into Harvard College, it is required that students take the SAT or the ACT, as well as SAT Subject Tests. Harvard will also look at other factors during admission such as your application essay, high school transcript, work experience, GPA (Grade Point Average), your interview, recommendations, and most importantly, your character and personal qualities.

    Every month we look at a different artist. We think Haroshi is super cool—he makes sculptures(雕塑) from skateboards.

    Haroshi is in his late 30s. He's a skateboarder but he also makes things from wood. He began skateboarding when he was 15 years old and he loved it. He used to skate every day. Now, if you know anything about skateboarding, you'll know that skateboards don't last forever because they break. But Haroshi didn't throw his out because he was fond of them. Over time he built up a big collection and at the same time he learnt about all the different types of skateboard. Surprisingly, not all skateboards are of the same shape and actually they are often built in different ways. By the time he was 25, he had an enormous collection of old skateboards.

    He decided he had to do something with them so he started to cut them up. As he was doing that, he noticed some interesting patterns in the wood. He then cut more and stuck them on top of each other. The first thing he created from the wood was a piece of jewelry. He created something new from something old.

    Nowadays, however, he is known for his extremely large 3D wooden sculptures. His ideas generally come from skateboarding culture, ranging from skateboarding cats to cool trainers, but also everyday topics such as hurting yourself, getting better, being crazy about something and of course, growing up. All skateboarders will understand these. Haroshi has made over 40 pieces and each piece takes a very long time. There is no doubt that he is very talented but he's had no formal art training. He taught himself.

    Haroshi held an exhibition in London last month and three of us from @teenattack went along. As we entered the first room, we saw a huge bird that covered one wall. It was absolutely enormous! There was also a sculpture called Ordinary life. It looked like a broken leg—a very common problem, of course. It's incredible to think that these sculptures are all made from broken skateboards. But there's something else that is really interesting about Haroshi's work.

    In the twelfth century a sculptor called Unkei placed a glass ball in each of his works to show the heart of the piece. Haroshi also places something inside his sculptures—a piece of broken skateboard. In this way, he gives his sculptures life. We think that is just awesome!

Singapore researchers say they have developed a form of electronic skin that can create a sense of touch. They hope their invention will give people with prosthetic hands (假肢手) the ability to identify different objects.

The skin device measures 1 square centimeter. The system contains 100 small sensors that attempt to recreate things like texture (质地), temperature and even pain. The researchers call the device Asynchronous Coded Electronic Skin, or ACES, which can process information faster than humans' nervous system. Machine learning methods trained the device to recognize 20 to 30 different textures. It can even correctly read Braille letters most of the time, the researchers say.

The system does not require the users' movement to work. Humans need to slide to feel texture. But in this case the skin, with just a single touch, is able to detect textures of different roughness.

A demonstration showed that the device could identify the difference between a soft ball and a solid plastic one. "When you lose your sense of touch, you essentially become numb and prosthetic users face that problem, " said Benjamin Tee, leader of the research team. "So by recreating an artificial version of the skin, for their prosthetic devices, they can hold a hand and feel the warmth and feel that it is soft."

Tee said his idea for the device came from the movie Star Wars, when character Luke Skywalker loses his right hand and it is replaced with a robotic one. In the film, the new hand is able to experience touch sensations just like the real one.

The artificial skin technology is still going through experiments and development. But Tee said there had already been a lot of interest in the system, especially from the medical community. Tee said similar inventions that his team has developed include see-through skin that can repair itself when torn and a material for wearable electronic devices that gives off light.
