    Electrical devices (仪器) could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.

    The device connects to a person's knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.

    There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers (起搏器). It could even be used to assist in the movement of robotic arms and legs.

    The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version should be ready in one year.

    The developers hope the device will one day help developing countries. Nearly twenty-five percent of people around the world live without electric power.

    A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person's back that also produces power from walking. The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.

    What are the categories?

    There're five categories which are based on the Waste Hierarchy(层级). We appreciate that companies will have different strengths within those categories as they work towards Zero Waste. The broad categories are: waste prevention, re-use, recycle/recover, energy recovery, general.

    How do I enter?

    Submitting an entry is really easy! Just follow these few simple steps:

    1) Carefully read through the category information;

    ). Write your entry--it should be a maximum of 1,500 words and a word document;

    3) Arrange your supporting material into a single document--maximum six pages long;

    4) Complete the simple online entry form.

    Important dates

    While entries are welcomed all year round, these are key dates—this is to give the judges plenty of time to read through all the entries! These are listed in entry deadlines column below. Don't worry if you have just missed one of the entry deadlines, your submission will be automatically entered into the next session.

    You can submit a maximum of two entries per year—six months apart.

    Awards

    We understand that working towards Zero Waste is an ongoing journey and as such the

    Zero Waste Awards scheme offers organizations a structure to celebrate their progress along the way. The four awards are: Gold (76-100), Silver (51-75), Bronze (26-50), Highly Commended(0-25).

    Blowing bubbles is fun! The best thing about bubbles is that it's easy to make your own bubble solution(溶液). You can make as much as you want and blow as many bubbles as you'd like. If you add a "secret" ingredient(配料), you'll get bigger and stronger bubbles! Do just as follows:

    Measure 6 cups of water into one container, then pour 1 cup of dish soap into the water and slowly stir it until the soap is mixed in. Try not to let bubbles form while you stir.

    Measure 1 tablespoon of glycerin(甘油) or 1/4 cup of corn syrup（玉米淀粉） and add it to the container. Stir the solution until it is mixed together.

    You can use the solution right away, but to make even better bubbles, put the lid on the container and let your super bubble solution sit overnight. The soap mixture on the outside of a bubble is actually made of three very thin layers: soap, water, and another layer of soap. A bubble pops when the water that is trapped between the layers of soap evaporates(蒸发). The glycerin or corn syrup mixes with the soap to make it thicker. The thicker skin of the bubbles keeps the water from evaporating as quickly, so they last longer. It also makes them stronger, so you can blow bigger bubbles.

    Dip a bubble wand or straw into the mixture, slowly pull it out, wait a few seconds, and then blow. If you don't have a ready-made "bubble wand", you can make your own by cutting off the end of the bulb of a plastic pipet. Dip the cut end in solution and blow through the narrow end. You can also make a loop out of thin wire or pipe cleaner. Just twist a round end on your wire to blow the bubbles through. You can even make it heart-shaped, square or use other shapes if you're clever enough to bend it well.

    Imagine you're standing in line to buy a snack at a store. You step up to the counter and the cashier scans your food. Next, you have to pay. but instead of scanning a QR Code（二维码）with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your ear.

    Now, this type of technology might not be far away. As technology companies move away from the traditional password, biometric（生物特征识别的）security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

    In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then, using one's fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives. And since 2016, Samsung has featured eye-scanning technology in its top smart phones, while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometrics might not be as secure as we imagine. “Biometrics is ideally good in practice, not so much,” said John Michener, a biometrics expert.

    When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said. “The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million.” But it's already been done. In a video posted on a community website Reddit, two brothers showed how they were each able to unlock the same iPhone X using their own face. And they aren't even twins.

    “We may expect too much from biometrics,” Anil Jain, a computer science professor at Michigan State University, told CBS News. “No security systems are perfect.”

    Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splinter. “It's good to see biometrics being used more,” Jain told CBS News, “because it adds another factor for security. But using multiple security measures is the best defense.”

    The United States of America is faced with serious traffic problems. Too many cars travel on the freeways to and from the city. This heavy traffic causes delays and lots of pollution from cars that are using their engines but not moving anywhere. Many cars going nowhere is called a "traffic jam".

    While many cities in the United States have traffic problems, some of the worst are in Los Angeles, California, which is a big city with a large downtown area. One of the reasons why there is so much traffic is that few people use public transportation to get around.

    Experts say one possible solution to the traffic problems in Los Angeles would be to make people want to use the public transportation system of buses instead of their own cars. People say the buses should be made easier, faster, less costly and more dependable than driving a car.

    One suggestion is to reduce the cost of taking the bus. Also, Los Angeles could make the buses easier for people to use. The buses could travel to more places in the city. And there could be more special lanes on the freeways that only buses could drive in. These changes would make taking the bus faster and easier than driving a car.

    Other experts have said that the best way to ease traffic problems is to charge people money to drive on the freeways. These charges, or tolls, would be for the most crowded roads. The tolls would be in effect during the times of a day when most people drive to work and home. These times in the morning and late afternoon are called "rush hour". People would try to avoid driving on these roads, which would decrease the amount of traffic. Also, the money collected from these tolls could be used to improve the roads and public transportation system.
