A small group of people around the world have started implanting(移植) microchips to link the body and the computer.

    Mr. Donelson and three friends, who had driven 100 miles from their homes in Loockport, New York, to have the implants put in by Dr. Jesse Villemaire, whom they had persuaded to do the work, are part of a small group, about 30 people around the world, who have independently put in microchips into their bodies, according to Web-based reports.

    At a shop William Donelson was having a four-millimeter-wide needle put into his left hand. “I'm set,”he said with a deep breath. He watched as the needle pierced(刺穿) the fleshy webbing between his thumb and a microchip was set under his skin. At last he would be able to do what he had long imagined: strengthen his body's powers through technology.

    By putting the chip inside—a radio frequency identification device (RFID)—Mr. Donelson would have at his fingertips the same magic that makes safety gates open with a knock of a card, and bridge and tunnel traffic flow smoothly with an E-Zpass. With a wave of his hand he plans to connect with his computer, open doors and unlock his car.

    Implanting the chip was relatively simple task but very meaningful to Mr. Doneselson, a 21-year-old computer networking student so interested in the link between technology and the body that he has data-input jacks(数据输入插空) inside his body. They might lead to an imagined future when people can be connected directly into computers. His new chip is enclosed in a glass container no bigger than a piece of rice and has a small memory where he has stored the words “Technology”.

    Some doctors have done the piercing in people's homes, and others have implanted chips in their offices after patients signed forms showing the fact that long-term studies have not been done on their safety. Piercers treat the implants much like any other medical operation steps, instructing people to keep the site dry, and advising them that swelling and redness should last a week.

What Cocktail Parties Teach Us

    You're at a party. Music is playing. Glasses are clinking. Dozens of conversations are driving up the decibel (分贝) level. Yet among all those distractions, you can tune your attention to just one voice from many. This ability is what researchers call the “cocktail-party effect”.

    Scientists at the University of California in San Francisco have found where that sound-editing process occurs in the brain — in the auditory cortex (听觉皮层) just behind the ear, not in areas of higher thought. The auditory cortex boosts some sounds and turns down others so that when the signal reaches the higher brain, “it's as if only one person was speaking alone,” says investigator Edward Chang.

    These findings, published in the journal Nature last week, explain why people aren't very good at multitasking — our brains are wired for “selective attention” and can focus on only one thing at a time. That inborn ability has helped humans survive in a world buzzing with visual and auditory stimulation (刺激). But we keep trying to push the limits with multitasking, sometimes with tragic (悲剧的) consequences. Drivers talking on cellphones, for example, are four times as likely to get into traffic accidents as those who aren't.

    Many of those accidents are due to “inattentional blindness”, in which people can, in effect, turn a blind eye to things they aren't focusing on. The more attention a task demands, the less attention we can pay to other things in our field of vision. Images land on our retinas (视网膜) and are either boosted or played down in the visual cortex before being passed to the brain, just as the auditory cortex filters sounds, as shown in the Nature study last week. “It's a push-pull relationship — the more we focus on one thing, the less we can focus on others,” says Diane M. Beck, an associate professor of psychology at the University of Illinois.

    Studies over the past decade at the University of Utah show that drivers talking on hands-free cellphones are just as influenced as those on hands-held phones because it is the conversation, not the device, that is distracting their attention. Those talking on any kind of cellphone react more slowly and miss more traffic signals than other motorists.

    Some people can train themselves to pay extra attention to things that are important — like police officers learn to scan crowds for faces and conductors can listen for individual instruments within the orchestra as a whole. Many more think they can effectively multitask, but are actually shifting their attention rapidly between two things and not getting the full effect of either, experts say.

    Forest Schools originated in Sweden in the 1950s and spread to other countries, particularly Denmark where they have become an important part of the Danish early years program.

    In a typical Danish Forest School, young children from 3 years are taken into the forest for 4 hours each day of the week. They take no toys with them, but instead use only what the forest provides (and their imaginations) to develop their games. There is a primitive hut in the forest, which is used in extreme weather. Activities are child-led and fun, such as finding small animals or stomping in puddles. Because of high adult to child ratios, children can safely try out activities which are often considered too dangerous, such as climbing trees or lighting fires, and by dressing the children in good protective clothing, they are able to play freely. By setting children small manageable tasks at which they are unlikely to fail, and giving genuine praise, children's independence and confidence grow.

    A Swedish scientific study found that children in the Forest School are more balanced and socially capable, have fewer sick days, are more able to concentrate and have better co-ordination than the city nursery children. The primary reason appeared to be the greater opportunities to play in nature, so that children play for longer at a time, tending not to disturb each other as much as children in the city nursery. The study observed that where children were interrupted, they became irritable, their stress level rose, and their ability to concentrate fell.

    The study also showed that the Forest School children had 25 % fewer sick days than the city children. One reason for this is that the air is nearly always better outside than indoors. Outside a child is not so exposed to virus and bacteria and not so likely to be infected by other children. Another reason may be that, since stress has been shown to have a negative effect on the immune system, high stress levels may be weakening the city children. The Forest School children, on the other hand, are in a pleasant, natural, fun and less stressful environment.

    Carri Kessler and her husband Will named their daughter Ottilie after a friend from the UK, who helped them a lot. However, right after their baby girl was born, the couple noticed a big problem: "No one could remember her name and no one could pronounce it, were going to keep having to introduce her!" Kessler told Today.com.

    The situation then grew worse as Kessler's grandmother admitted to sticking Post-it notes around the house to help remind her of Ottilie's name which can be pronounced either Ott-ill-ee or Oh-TEEL-ya. Three months after Ottilie was born, the Kesslers have decided to legally change their daughter's name. The couple came up with two possible names. They then settled on Margot after talking to a name expert.

    The Kesslers situation is not uncommon as an increasing number of parents experience the same as the Kesslers. According to Baby Center Canada, 11% of its users wish they could change their children's names due to being over popular mispronounced or simply unfitting. Parents care a lot more and think a lot more about names now than their parents.

    To deal with this, a number of name experts now offer services to help parents choose the right name. Couples have also looked for help from the Internet to choose their baby's name. However, parents can change their child's name in the event that they regret their choice. In Canada, the rules vary in each province. For instance, in Ontario, the child must have lived in the province for the past 12 months, or since birth if under the age of one. Each of the child's legal guardians(监护人)must also give permission.

With gas prices rising and airport security lines snaking longer than ever, why not book your next domestic vacation on a train? Compared to other alternatives, it's comfortable and relaxing. Here is some advice on how to make a trip by rail as pleasant as possible. 

Plan ahead. Most long-distance trains, especially the sleeping car accommodations, sell out very quickly.{#blank#}1{#/blank#}But no matter when you travel, it's a good idea to make your reservations at least 90 days in advance. 

Use a travel agent. Consider turning your travel plan over to a travel agent and letting him double-check all the details, make suggestions, and then handle the actual reservations. A good one can sometimes find you discounted tickets.{#blank#}2{#/blank#}Then you won't have to walk through several cars on a moving train three times a day for your meals. 

Bring a blanket.When you're riding on trains, you won't be provided with a blanket for free, even if your trip is an overnight one.{#blank#}3{#/blank#}In the summer in particular, the air conditioning can make them quite cold. 

Arrive early. Most trains operate just once a day and some run only three times a week, so missing yours can be a disaster.{#blank#}4{#/blank#}Note: The times listed on the schedules are departure times, not arrival times. 

Have fun.{#blank#}5{#/blank#}Read a book, knit, do a crossword puzzle, or simply watch the world unfold outside the window. To calculate your speed as you do, divide 3,600(the number of seconds in an hour)by the number of seconds it takes you to travel one mile(the distance between two mileposts). If it takes the train 53 seconds to travel one mile, you're going 67.92 mph.

A.Train trips aren't for impatient types.

B.You'll have views from both sides of the train.

C.The temperature on rail cars is often hard to control.

D.That's particularly true during busy summer months.

E.You might have to wait longer than 24 hours to catch the next one.

F.Chances are the cost will be a lot less than the cost of one bedroom.

G.He may also book you in a sleeping car that's right next to the diner.
