    What if you arrived home to find it delicious hot meal waiting for you, prepared by your very own kitchen robot? It might sound like science fiction. but professors at the university of Tokyo  have  taken  the first steps toward making that  scenario a reality. The team recently introduced a humanoid kitchen robot that can pour and other drinks into cups and serve the m to guests. When teating is over, the robot can also wash the dishes and put them away.

    In California, another interesting kitchen robot has been developed, called Readybot. It can pick up objects and either store them in  cabinets (橱柜）or put them in the trash. It also carries a separate floor-cleaning robot that can operate by itself. Unlike the Japanese robot, Readybot just looks more like a large box with arms and wheels.

    Readybot was created by engineers and designers who established a club called the Readybot  Challlenge. They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks. Readybot is just the first step in their plan to create a robot that can do jobs not  only  in  kitchens but  in other rooms of homes and in offices as well.

    Clearly there are technological difficulties to solve before robots can cook a Complete dinner, and there arc also many safety concerns (忧虑） .Not everyone (especially parents) would be comfortable with the idea of robots in their house, manipulating hot pans and sharp knives. The European Commission recently funded(资助） a project to study these concerns. According to lead researcher Professor Chris Melhuish,“ Enabling  robots to work  safely with humans is a key need for the future development of robotics.”

    Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health．

    In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children's diets．Children should not eat more than two slices of pizza for a meal，and should pair that with salad, rather than with another high-calorie food，the researchers concluded．

    “Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands．”Said Lisa Powel, director of the Illinois Prevention Research Center．

    Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them．Studies have found pizza is among the greatest sources of calories for children．

    “Since pizza remains a common part of children's diet, we need to make 'healthy' pizza．”Powel said．To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content,” she said．

    Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research. “Many foods are eaten too frequently and in large sizes,” said Tindall．To solve the problem, people don't have to give up eating pizza, but instead, they can eat smaller and healthier pizza，”she said．

    “Make it at home, instead of ordering it out where you don't have any control over how it's made.” Tindall said. “When we make it at home, we can choose healthier ingredients，increase the vegetables, reduce fat, and put in less cheese．Pizza doesn't have to be just pepperoni(意大利辣香肠)and cheese．”

    Most heroes are not super. They don't appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.

    Bike Batman is a 30-year-old married engineer who lives in Seattle, Washington. He's a cyclist who also buys and sells bikes as a hobby.

    About three years ago, he was looking for a bike for his wife. He found one on Craigslist, a website where people list things they want to sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they're taken. The bike, which he was considering purchasing, clearly matched one reported stolen on Bike Index. Then he called the person who claimed to be the bike's owner and arranged to meet him— supposedly to complete the sale. When the two men met, Bike Batman told the thief, “You've got two options. You can wait until a police officer gets here, or you can just get out of here.” You can imagine what the thief did.

    After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes, the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.

    His nickname came from a discussion with a police officer who suggested he be called “Robin Hood”. Since he wasn't exactly stealing from the rich and giving to the poor, “Batman” seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle's reputation as a friendly city.

    TESCO has announced it is banning the sale of energy drinks to teenagers, and that the big move will begin in weeks. The supermarket has joined a host of major names banning teenagers from buying high caffeine, high-sugar drinks. The government indicates that the principal question to be determined is whether the purchasing restrictions will apply at the age of 16 or 18.

    Theresa May said the consultation was linked to the government's childhood obesity (肥胖) strategy and said it was necessary to examine the consumption of energy drinks "often because they are sold at cheaper prices than soft drinks".

    The principal reason for the ban is the high level of caffeine in the energy drinks, which has been linked to a string of health problems for children, including head and stomach aches as well as sleep problems.

    Energy drinks often also have higher levels of sugar than soft drinks. According to government figures, sugared energy drinks have 60% more calories and 65% more sugar than normal soft drinks and sugar is one of the largest causes of obesity.

    Jamie Oliver said he welcomed the ban on energy drink sales because "too many children are regularly using them to replace breakfast" and "teachers from across the country have told me how their lessons are disrupted because of these drinks".

    A Downing Street source added that there is no evidence that energy drinks have any nutritional value in children's diet. That accounts for the government's action on measures to tackle childhood obesity and improve children's health.

    The move is the latest step in an approach in relation to childhood obesity and health. According to European Food Safety Authority research, two-thirds of 10 to 16-year-olds regularly consume energy drinks, along with 18% of 3 to 10-year-olds.
