	They are not just chopsticks ． Scientists at an American university have invented a pair of electronic chopsticks that can change the taste of food．When you put the chopsticks in your mouth，they can make you feel the taste becomes better，such as making sweet food taste sweeter or salty food less salty．Soon the scientists are going to try their technology on bottles，cups and spoons．
	It's not just a sticker ． It's said that about 52%of the fruits of the earth go bad before reaching the buyers．Scientists from Malaysia thought of a simple way to solve the problem﹣tiny stickers（小粘贴）that are made out of some natural materials．Put the stickers on fruits，and the fruits can keep fresh up to two weeks．
