　　　 Most people would agree that it would be wonderful if humans could regenerate (再生) limbs．Those who have lost their arms or legs would be complete again．The day is still far off when this might happen．But in the last 10 years, doctors have reported regeneration in smaller parts of the body, most often fingers.

　　　 Regeneration is not a newly-discovered process．For centuries, scientists have seen it work in some kinds of animals．Scientists now are looking for a way to turn on this exciting ability in more highly-developed animals, including humans．Their experiments show that nerves (神经), cell chemistry and the natural electric currents in the body all seem to have a part in this process.

　　　 The body of every animal contains general purpose cells that change into whatever kind of cells the body needs．These cells collect around the wound．They form a mass called a blastema (芽基)．The cells of the blastema begin to change．Some became bone cells, some muscle cells, some skin cells．Slowly, a new part re-grows from the body outward．When completed, the new part is just like the old one.

　　　 More than 200 years ago, Italian scientist Luigi Spallanzani showed that younger animals have a greater ability to regenerate lost parts than older animals．So do animals lower on the ladder of evolutionary (进化的) development．The major differences seem to be that less-developed animals have more nerves in their tails and legs than humans do in their arms and legs.

　　　 Another helpful piece of information was discovered in the late 1800s．Scientists found that when a creature is injured, an electrical current flows around the wound．The strength of the current depends on how severe the wound is and how much nerve tissue (组织) is present.

　　　 She is widely seen as proof that good looks can last for ever．But, at nearly 500 years of age, time is catching up with the Mona Lisa.

　　　 The health of the famous picture, painted by Leonardo da Vinci in 1505, is getting worse by the year, according to the Louvre Museum (卢浮宫) where it is housed.

　　　 “The thin, wooden panel on which the Mona Lisa is painted in oil has changed shape since experts checked it two years ago,” the museum said．Visitors have noticed changes but repairing the world’s most famous painting is not easy．Experts are not sure about the materials the Italian artist used and their current chemical state.

　　　 Nearly 6 million people go to see the Mona Lisa every year, many attracted by the mystery of her smile．“It is very interesting that when you’re not looking at her, she seems to be smiling, and then you look at her and she stops,” said Professor Margaret Livingstone of Harvard University．“It’s because direct vision (视觉) is excellent at picking up detail, but less suited to looking at shadows．Da Vinci painted the smile in shadows.”

　　　 However, the actual history of the Mona Lisa is just as mysterious as the smile．Da Vinci himself loved it so much that he always carried it with him, until it was eventually sold to France’s King Francis I in 1519.

　　　 In 1911, the painting was stolen from the Louvre by a former employee, who took it out of the museum, hidden under his coat．He said he planned to return it to Italy．The painting was sent back to France two years later．During World War II, French hid the painting in small towns to keep it out of the hands of German forces.
