A chip inserted in a young quadriplegic's (四肢麻痹患者) brain is already improving his quality of life. Soon the benefits may be more widespread.

    A 25-year-old man unable to move from the neck down recently did what many assumed impossible. After a knife attack that had left him paralyzed, all he could move was his head, which he used to push a switch and call for a nurse. And he could turn his wheelchair by blowing into a straw near his face. That was it.

    Then last June, a Foxborough (Mass.) company called Cyber Kinetics opened the man's skull and inserted a special chip no larger than a baby aspirin. That insert has given him a few additional and precious abilities. When connected to a special computer via a cable, the chip translates the young man's thoughts into commands that let him move a cursor across a PC screen and open e-mail. He can draw a circle with a computer painting program. And he can use a robotic hook(钩) to perform simple tasks like picking up a candy and sliding it across a table.

    All he has to do is to think.

    Several new studies have begun or been completed in the past year. In fact, more than half of the scientific papers in this field, called brain-to-computer interaction (BCI), have been published in the past two years, notes Jonathan Wolpaw, a research physician at Wadsworth Center, the New York State Health Dept.'s research laboratory.

    Brain surgeries (手术) are no longer rare: Thousands of Parkinson's disease patients have had special devices inserted in their brains to ease uncontrollable shaking and other symptoms. The inserts themselves have improved, so the body doesn't reject them as furiously(猛烈地). And significant development has been achieved in software used to interpret the brain's signals and change them into commands understood by computers.

    But increased demand for thought technology remains the biggest reason for the field's progress. Today, 4 million Americans live with paralysis according to the Christopher Reeve Paralysis Foundation.

    Scientists hope that thought technology will reduce the impact of such disabilities. People with spinal-cord injuries, for example, often lose their ability to walk because the communications network between their brain and their legs has been interrupted. The brain still commands the leg muscles to move, but they don't hear its orders.

    Thought technology, scientists hope, will bridge this communications gap. "Our goal is for you to see paralyzed people eating at a restaurant and for you not to know that they are paralyzed," says John Donoghue, founder and chief scientific officer at Cyber Kinetics.

    Mom and Dad are two of the most important people in your life.You probably see at least one of them every day. If your dad worships（崇拜）the Pittsburgh Stealers,you're likely to grow up being a big fan of that football team.And if your mom loves to read,you just might grow up carrying a book wherever you go,just like she does.

    Here are four ways you can stay.close:and build a strong relationship with your parents.

    ⑴Spent time together.How much time do you spend just enjoying each other's company?

    Instead of playing a computer game or watching TV,maybe you can ask your mom and dad to play with you.Go outside together,try a board game,or read a book out.

    ⑵Share your feelings and ask for help.Your mom or dad might not know that you're having a problem.Tell a parent if you're sad or struggling with something.

    ⑶Show your care. Some families are always kissing, hugging, and saying "I love you". It's important to show that you care for each other. In addition to kisses and hugs, kids and parents show their love by respecting each other, being caring, polite, and thoughtful.

    ⑷Whatever you do, do your best! You, don't have to be perfect, but when you do your best, you make your parents proud. It makes them happy to see how you're turning into such a great kid. Why? Because it lets them know they're doing a good job.

Racing Timing

    The 5 km run will be timed using the BIB-TAG system. Your race number will have a timing device attached to the back of the race number; don't remove or bend this device. Simply wear the Bib on the front of your body on the outside of your clothing so it is visible and facing forward. You don't need to return the Bib, which is disposable.

The Turkey Trot is also a kick-off event for our weekend long “FITNATIC” celebration—we also have a huge number of events and specials all weekend. For more information, please visit http://www.fleetfeettulsa.fitnatic.com.

See you on Friday.

London Underground

    The world's first subway was built in London in 1863. At the time, the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work, they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems, the idea of the London Underground, the first subway system, was born.

    The plans for building the Underground met with several problems and delays, but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30,000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed), and pleasant decorations inside each of the cars. However, the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰), as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems, riding in the Underground did catch on. It carried 9 million riders in its first year.

Fishy Weather Conditions

    Laj amanu，Australia，is a dry little town，sitting right on the edge of the Tanami desert. Can you imagines How surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado，only it forms above oceans，lakes，or rivers. Like a tornado，a waterspout moves in a circle at high speeds. When it moves above the water，it tends to carry the fish with it，as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still，the fish in Honduras were very much alive when they rained down to the ground，but they were all blind. In England and Australia，it rained fish and snakes，and none were blind. It was difficult to puzzle out，but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep，underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras，scientists began to connect some dots. Clearly，these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent，and each time，people have tried in various ways to explain this strange phenomenon. Historically，villagers thought the “fishes from the heavens” might be answers to prayers for food. Others suggested that floods overran river banks and oceans，leaving the fish on the city streets. No scientist had actually seen the rain as it occurred，only the fish left on the ground. But in 1990，a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.
