On a Saturday night at home while relaxing with friends, a dog showed up at the house. In an attempt to find the legal owner and return the dog, we knocked on the door of the legal owner and an old man opened the door. This was the start of an interesting week.

    The old man sat down, made himself at home, and gifted us the dog. After a brief visit, he left, and we were now the proud owners of this dog. It takes experience and knowledge to know that our lifestyle can't satisfy the needs of this dog; the owner that gifted us the dog was mismatched for him as well.

    Three attempts to return the dog to his old owner failed. (I think he was avoiding us.) Because our lifestyle didn't allow us to give this poor dog the attention he needed, he disturbed the neighbors. They got involved. After we shared the story, they gained a new perspective and wisely stepped in to help us find a solution.

    One week later it was decided that dog would be picked up from us by the old neighbor. He would then return it to the previous owner who was more equipped to care for it.

    When faced with unexpected challenges in life, it helps to see everyone's perspective. We have to look at one another's perspective to solve a problem with honesty, experience and knowledge. That's the sign of a leader. Although the old neighbor typically has little to do with leadership, it did bring a neighborhood together to understand one another and work as a team to solve a problem.

    You use her as a shoulder to cry on. She texts you back with casual jokes. But she, Xiaoice, is only a virtual chatbot（虚拟聊天机器人）.

    Xiaoice, Microsoft's latest artificial intelligence robot, was briefly released in 2014, and returned to WeChat in 2015, where she became a big hit. Millions of young Chinese now exchange messages with her daily, The New York Times reported. On WeChat, Xiaoice is an official account. After following it, users can start text-based conversations with Xiaoice.

    “Her incredible learning ability was why people loved to talk with Xiaoice,” Liu Jinchang, a researcher at High-tech Research and Development Center under the Ministry of Science and Technology, told China Daily. Apart from her ability to identify photos and send emojis（表情符号） in conversations, Xiaoice gains 45 percent of her knowledge from interacting with users, China Daily reported.

    Chatbot programs first appeared in the mid-1960s in the US. Driven by top tech companies, they are becoming smarter and more common. For instance, IBM's latest artificial intelligence program served as an academic consultant at Australia's Deakin University, answering students' questions about course schedules and financial aid. Apple's Siri and Amazon's Alexa have been used as voice assistants who can read news, play music and even make jokes for their users.

    These programs are expected to move beyond smartphones, into televisions, cars and living rooms, The New York Times pointed out. However, it may take decades before scientists develop a “Samantha”, the advanced chatbot seen in the fiction film Her. In the film, Samantha has a romantic relationship with her user played by US actor Joaquin Phoenix. Many viewers were enthusiastic about this fantasy of virtual soul mates.

    How to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else).Registered dietitian(营养专家) Barbara Morrissey suggests that a few simple rules can help.

"Go for nutrient dense foods that contain a multiple of nutrients," she suggests, "For example, select whole wheat bread as a breakfast food, rather than coffee and cake. Or drink orange juice rather than orange drink, which contains only a small percentage of real juice——the rest is largely colored sugar water. You just can't compare the value of these foods, the nutrient dense ones are so superior," she emphasizes.

    Morrissey believes that variety is not only the spice of life; it's the foundation of a healthful diet. Diets which are based on one or two foods are not only virtually impossible to keep up the strength, they can be very harmful, she says, because nutrients aren't supplied in sufficient amounts or balance.

    According to Morrissey, trying to find a diet that can cure your illnesses, or make you a super woman is a fruitless search. As women, many of us are too concerned with staying thin, she says, and we believe that vitamins are some kind of magic cure to replace food.

"We need carbohydrates(碳水化合物) protein and fat—they are like the wood in the fireplace. The vitamins and minerals are like the match, the spark, for the fuel," she explains, "We need them all, but in a very different proportion. And if the fuel isn't there, the spark is useless.”

    As the temperature rises, sweaty humans are making a response that is further worsening the problem of climate change. At present, the world just has 1.6 billion air conditioning units, but these units use a surprising total of ten percent of all global electricity supply. While less than a third of families globally are so equipped, the most AC-addicted countries are Japan (in 91 percent of families), the US (90 percent) and South Korea(86 percent).

    New research by the International Energy Agency (IEA) guesses that the total number of AC units is likely to increase to over 5.6 billion by 2050－equal to ten new units being sold every second for more than 30 years－with sales driven particularly by India, China and Indonesia. This will make the use of air conditioning one of the world's largest demands for energy.

    "Growing electricity demand for air conditioning is one of the most critical blind spots in today's energy debate," argues Faith Birol, executive director of the IEA. "With rising incomes, air conditioner ownership will skyrocket, especially in the developing world. While this will improve daily lives, it is quite necessary that efficiency performance be prioritized."

    Birol and the IEA stress the need for new efficiency standards to ensure that consumers are at least buying units that require significantly less power to function, therefore decreasing the total energy demand. Variations on the traditional "vapor compression" technology, which has formed the basis for AC units for more than a century, may appear really important. A water-based system was recently developed by researchers at the National University of Singapore (NUS), which uses 40 percent less electricity and produces only one by-product: drinkable water.

    "Our cooling system can be tailored for all types of weather conditions, from wet climate in the tropics to dry climate in the deserts," says associate professor Ernest Chua at NUS. "While it can be used for indoor living and commercial spaces, it can also be easily used to provide air conditioning for blocks of buildings in an energy-efficient manner."

Do you want to learn the material you're studying—like, reallylearn it? {#blank#}1{#/blank#}One learning theory suggests that if you overlearn, you'll gain the ability to do something without having to think about it — and eventually obtain more knowledge. Here's what overlearning is and how to do it.

What is overlearning?

Simply put, overlearning means studying something even once you're sure you know it. Don't stop reviewing or studying just because you succeeded in memorizing something. {#blank#}2{#/blank#}

The purpose of overlearning is to make the task easy to ensure it is completed to a high standard with no stress. For example, a student wants to pass their spelling test which has 10 words. Knowing about overlearning, she doesn't just memorize each word, but also learns about the origins of each word. {#blank#}3{#/blank#} Similarly, a teacher wanting to learn about teaching strategies might not simply read one book — they may read ten books, watch videos, attend lectures (and maybe even write their own book).

How do you overlearn?

{#blank#}4{#/blank#} For instance, when using the Leitner method, always review all the flashcards you're assigned on a particular day, even if you feel like passing over them because you got them right last time. Repeatedly going over material you know well is the key to overlearning and eventual automatic recall.

Schedule blocks of time in your week for reviewing materials you've already mastered. {#blank#}5{#/blank#} Continually reintroducing familiar ideas to yourself will dig them deeper into your long term memory.
