Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed.
The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks.
Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models.
The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach.
“ We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships,” he said. “ To me, archeology is like search and rescue, but everyone has been dead for 5,000 years.”
The doctors are very excited about the potential for surgical robots to do things that humans can’t do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves.

There are a number of special days of the year that are celebrated in different countries. The origins of most of the days are unknown. They were certainly not created by individual people. Other days, however, especially those celebrated in western countries, often owe their origins to a particular person. One of the most popular of these, even though it is fairly recent, is Mother’s Day. Mothers have always been highly regarded in all cultures. The ancient Romans had a festival known as Hilaria, during which children took presents to the temple of the “Mother of the Gods”. The Christian Church adopted this idea and called it Mothering Sunday. However, over the years this custom was gradually forgotten and almost disappeared by the end of the 19th century.
Born in 1864 in Virginia, USA, Anna Jarvis was a school teacher and believed children should show gratitude to their mothers for all their love and care. Encouraged by a friend, she wrote to thousands of important people—politicians, churchmen, doctors, city officials—and asked them to support her idea: a special day of the year for thanking mothers.
In 1910 the Governor of West Virginia introduced Mother’s Day into the state. The date chosen was May 10—the second Sunday in May, which is still observed in America today. This date was chosen because May 10 was the date on which in 1908 Anna Jarvis’s mother had died. In 1914 President Woodrow Wilson made May 10 the official date for Mother’s Day throughout the United States.
Soon there was a Mother’s Day International Association and the custom began to be adopted in many countries of the world.
Anna Jarvis, a sad and disillusioned(失望的) woman, died in 1948. The custom she had worked so hard to establish and which had become almost universal had lost its original purpose. It had been taken over by business. Like Christmas, the giving of presents and the sending of cards had become a multi-million-dollar industry.
