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.”

    The town of Green Bank, West Virginia, is the site of the largest radio telescope in the world, so Internet connections and anything else that can create electromagnetic(电磁的) waves, such as smart phones and microwave ovens, are banned.

    Green Bank is frozen in time, somewhere in the 1950s, because there's a 33,000-square-kilometer zone of silence due to the telescope. Cell phone towers are forbidden.

    The closer you get to the telescope, the greater the restrictions. There's a 16-kilometer radius(半径) around the observatory where radio-controlled items, even toys, cannot be used.

    Telescope employees even work in a special room that blocks electromagnetic waves from leaving it. “Here imagine a submarine(潜艇), water cannot get inside, and so this room is an electric submarine. No electromagnetic waves can get into this room, just as you can't go beyond it,” Michael Holstein, an observatory officer, said.

    The size of a football field, the telescope is so sensitive that it could pick up signals sent from an alien world. And scientists can't wait for that to happen.

    “All the signals that we now receive with the help of telescopes are signals that come from cosmic objects — stars, galaxies. We have not yet received anything from intelligent civilizations,” scientist Richard Lynch said.

    Local people respect the work of the scientists. “Yes, we are different. Many would say that we live the old-fashioned way, in the past. But for us, it's just the way of life that we have always lived,” Sherry said.

    “When we want to meet friends, we just call each other on a wire phone. And instead of sitting in front of your screen, we talk, we go fishing, to the mountains,” resident Sherry said.

    For the latest news, residents read the weekly local newspaper. When she's looking for a phone number, Sherry reaches for the phone book.

    And instead of Facebook, Sherry enjoys daily conversations with her customers. In this town, everyone knows each other and communication is face to face.

    Many animals recognize their food because they see it. So do humans. When you see an apple or apiece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

    Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A land of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

    Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health Choosing the right food, therefore, has become an area of study in modern life.

    Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs' fossils(恐龙化石) because dinosaurs died out millions of years ago.

    It's very difficult for the scientists to reach an agreement because different results can be got from the same fossils. Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck(陷入)all at once. Or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.

    Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “That's pretty much settled at this point.” Says Paul Sereno. A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.

    As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs, birds and crocodiles for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.

    There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.

Life Begins on Board Your Next Cruise(邮轮)

On a cruise, it's all about choices. And never about effort or annoyance. Simply step aboard and float away, as your grand accommodation takes you from port to port, country to country. Maybe you haven't been on a cruise yet. Let's see what it might look like.

Rise and shine

Everyone is a morning person on a cruise. Wake up to find yourself floating joyfully somewhere out on the horizon, between vast blue skies and rolling oceans. You've travelled far through the night, and each morning begins with a completely new and foreign destination calling from outside your window. What a way to start your day!

Breakfast of champions

Before the morning truly begins, spend some time relaxing on the top floor with a steaming cup of coffee and warm French pastries, taking in the unbelievable views and the fresh sea air. Or head to one of the many restaurants on the ground floor to find a rich meal fit for a king, then walk to the front of the ship and have some fresh fruit and American pancakes in the open-air market.

Ease into your day

Energize your morning with a yoga class, strengthening your body on the open-air board, palms stretched to the sea. Hit the gym for a refreshing workout or take a swim that will set you up for the day. If you are not so sporty, simply spend your morning sitting by the pool reading a book, perhaps losing yourself in the history, culture and legends of your next port of call.
