Supermarkets are trying out new computers that make shopping carts more intelligent (具备智能的). They will help shoppers find cups or toilet soap, and keep a record of the bill.

The touch-screen devices (触摸屏装置) are on show at the Food Marketing Institute's exhibition here this week. "These devices are able to create value and get you around the store quicker," said Michael Alexandor, manager of Springboard Retail Networks Inc., which makes a smart cart computer called the Concierge.

Canadian stores will test the Concierge in July. A similar device, IBM's "shopping buddy," has recently been test-marketed at Stop & Shop stores in Massachusetts.

Neither device tells you how many fat grams or calories are in your cart, but they will flash you with items on sale. The idea is to make it easier for people to buy, not to have second thoughts that maybe you should put something back on the shelf.

"The whole model is driven by advertisers' need to get in front of shoppers," said Alexandor. "They're not watching 30-second TV ads anymore."

People can use a home computer to make their shopping lists. Once at the store, a shopper can use a preferred customer card to start a system (系统) that will organize the trip around the store. If you're looking for toothpicks, you type in the word or pick it from a list, and a map will appear on the screen showing where you are and where you can find them.

The devices also keep a record of what you buy. When you're finished, the device figures out your bill. Then you go to the checker or place your card into a self-checkout stand and pay.

The new computerized shopping assistants don't come cheap. The Buddy devices will cost the average store about $160,000, and the Concierge will cost stores about $500 for each device.

In some children who go blind, certain parts of the brain that normally control vision appear to switch jobs and focus instead on sound, a new study has found.

The study, by researchers at the University of Montreal, involved 7 adults who could see and 12 adults who had lost their vision when they were children. Each participant sat in a room with 16 loudspeakers at different locations. The room was designed so that there were no echoes. During the experiment, the speakers irregularly produced sounds. Participants had to point to where the sounds were coming from. Meanwhile, the researchers monitored blood flow in the brains of the participants to see which brain structures were working during the task.

The results showed that five of the blind participants were very good at pointing to where sounds were coming from. In these people, blood flow increased in the visual cortex- an area at the back of the right side of the brain. This part of the brain is usually associated with vision.

The other seven blind participants showed no increase in activity in the visual cortex. These people didn't do very well at picking out where sounds were coming from. Now, the researchers are looking at whether these people have gained an enhanced sense of touch instead of sound to replace their lost vision.

The scientists say that their study shows how adaptable parts of the brain can be.
