　　American doctors say that mothers who smoke before their babies are born may slow the growth of their babies lungs. They say reduced lung growth could cause the babies to suffer breathing problems and lung disease later in life. Doctors in Boston, Massachusetts studied 1 100 children. The mothers of some of the children smoked, the other mothers did not. Doctors found that the lungs of the children whose mothers smoked were 8% less developed than the lungs of the children whose mothers did not smoke, and that the children whose mothers smoked developed 20% more cold and breathing diseases than other children later in life.

　　Another recent study found that children had a greater chance of developing lung cancer if their mothers smoked. The study also showed that the danger of lung cancer increased only for sons and not for daughters, and that the father's smoking did not affect a child's chance of developing lung cancer.

It's likely that everything you learned about America's ancient history is wrong.

   The new book, 1491, completely changes our understanding of the Americas before the arrival of Columbus in 1492.

                DID YOU KNOW?

   When Columbus landed there were probably more people in the Americas than there were in Europe.

   The peoples of North America had such healthy life-styles that as late as the 19th century they continued to be the tallest people on earth.

   Facts have shown that the Americas were populated as long as 33,000 years ago.

     4,000 years ago Mesoamerican farmers developed corn in a feat (技艺) of genetic engineering that still isn't completely understood.
