People in Ethiopian highlands have adapted to living at high altitudes. Cattle-raising people in East Africa and northern Europe
18、 have gained a mutation(突变) that helps them digest milk as adults. On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptationnot to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau,
19、 as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, theyve also built houses on stilts (支柱) in coastal waters. They are simply a stranger to the land, said Rodney C. Jubilado, a Univ

25、s more expensive, urban designers are using modern technology to help citizens avoid traffic jams, and shorten the time needed for bus waiting and other things. Technology is also used to cut costly waste.In Santander, a Spanish port city, parking is easy to find. As one car drives away, an undergro
26、und sensor shows that a parking space is now free. 400 sensors send messages to signs on streets, and GPS devices direct drivers to the nearest available parking spaces, reducing traffic jams. Trash is collected only when the bins are full and bus stop signs show exactly when the next bus is coming.
27、 The public parks are watered only when the soil gets dry. All this is made possible by 20,000 sensors installed on buildings, street posts and even buses. They are part of the smart city project, launched by the University of Cantabria seven years ago.University researchers like Luis Munoz regularl

Here, we give them the opportunity to see these ideas happen in real life, said Munoz. For example, the university helped a woman create an app that outlines the
