A great invention by an 18-year-old high school student grew out of a simple problem most teenagers meet with.

    “I'm a teenager and I have a cellphone and my cellphone battery always dies，so I was really looking for a way to improve energy storage，” Eesha Khare said on Tuesday. “That's how I came across the super capacitor.”

    The teenager who came from California, and graduated from high school last week，won a $50，000 prize on May 17，2013 at the Intel International Science and Engineering Fair for creating a device that can store enough energy to charge a cellphone in 20 to 30 seconds.

    “It charges very quickly and can store a lot of energy，” Khare said. “The cool thing is that it's a lot thinner than one strand of hair.”

    Khare hasn't used her invention to recharge a cellphone yet，but she used it to power a light-emitting diode (LED) in order to show its capability(容量). If used on cellphones，the supercharger would slide on to the phone's battery to juice it up in a matter of seconds. The technology isn't available to consumers yet，and it could be years until it is.

    At an Intel event in Phoenix，Khare won the Intel Foundation Young Scientist Award，taking second place overall in the world's largest high school science research competition. She beat out more than 1，600 finalists from 70 countries. She said that she has been approached by several companies to continue her research，but she is now focused on attending Harvard University in autumn.

    “Right now，just my education，but hopefully we'll see what happens in the future，” she said about her plans. “I have a lot of interests，so we'll see what I do in the future.”

    Are you looking for some great beach movies? If you are, here are some beach movies that you are advised to watch.

    Blue Hawaii (1961)

    The first of Elvis Presley's Hawaiian three beach movies puts him into a setting(背景) as an army man who returns home for some surfing. Mom Angela Land sbury wants Presley to get a real job, but he's all about touring the island. Relax, Mom. Time for some wonderful parties!

    Beach Blanket Bingo (1965)

    The most famous of the “beach party” film of the 1960s stars Frankie Avalon and Annette Funicello. This movie is all about how fun it is to be a teenager, especially if you're at a party on the beach. Sunny, silly and energetic! You might find yourself laughing at the story and being happy after watching it.

    Six Days Seven Nights (1998)

    Anne Heche stars a woman unhappily engaged (订婚) to Frank Martin. On a vacation, she finds herself on a plane piloted by a sad man called Quinn Harris. They hate each other, which gets even more annoying once they two find themselves being alone on an island with no people. What better setting to fall in love?

Teen Beach Movie (2013)

    The Disney Channel remade the beach party movie in 2013 and brought us a new series of teens-dancing-on-the-beach movies. Ross Lynch is a kid suddenly thrown into a actual teen beach movie by a magic wave! Time to dress up fifties-style and sing tunes (曲调) like Surf Crazy and Cruisin for a Bruisin. In the end, the kids return to the real world. These are the movies to watch if you love happy endings.

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition (营养) “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the whole forest.

    “We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    Machines equipped with artificial intelligence (AI) have performed better than human beings in a high-level test of reading comprehension. Two natural language processing tools received higher test scores than humans in recent exams.

    One of the tools is a product of the American software maker Microsoft. The other was created by the Chinese online seller Alibaba Group. The company said that a deep-learning model developed by its Institute of Data Science of Technologies was the first to beat a human score in the reading comprehension test.

    The test is called the Stanford Question Answering Dataset. It was developed by researchers at Stanford University in California. It has over 100,000 questions and answers. They are based on information found in over 500 stories from the Wikipedia website. The answers to all the questions come from the reading material.

    The AI-powered machines were tested on whether they could provide exact answers to the questions after processing large amounts of information.

    Alibaba said its deep neural (神经的) network model received an “Exact Match” score of 82.44 on the Stanford test. Microsoft reported that a team at Microsoft Research Asia had a score of 82.65. It said the human score on the same questions and answers was 82.304. Many research organizations also appeared on the list—all with scores below 82.

    Alibaba said it has already used its reading comprehension model in different parts of its business. For example, the company is using machines to answer many incoming telephone calls from customers. The company says in the future, the technology could enable machines to guide visitors through museums or provide advice to medical patients.

    Microsoft noted that, overall, people are still much better than machines at understanding the complexity and nuances (细微差别) of language.
