Europe’s deadly outbreak of a rare form of E. coli bacteria (大肠杆菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(肠) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.

A recent study, which was published in last week’s Journal of the American Medical Association, offers a picture of how dangerous it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers has three times the possibility of a serious accident, compared with a teenager driving alone.
The authors also found that the death rates for teenage drivers increased greatly after 10 p.m., and especially after midnight. With passengers in the car, the driver was even more likely to die in a late-night accident.
Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with “really stupid behavior” than with just a lack of driving experience. “The basic issue is that adults who are responsible for giving out licenses fail to recognize how complex and skilled driving is.” he says.
Both he and the author of the study believe that the way to mitigate (使缓解) the problem is to have states set up so-called graduated licensing systems, in which getting a license is a process with several stages. A graduated license requires that a teenager first prove himself able to drive in the presence(在场)of an adult, followed by a period of driving with night of passenger restrictions (限制) before graduating to full driving rights.
Graduated licensing systems have reduced teenage driver crashes, according to recent studies.

I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent.
I no longer consider myself the center of the universe. I show up. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows(誓约) mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today.
So here's what I wanted to tell you today: Get a life. A real life, not a desire of the next promotion(提升), the bigger paycheck, the larger house.
Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure(空闲), it is work. Pick up the phone. Send an e-mail. Write a letter. And realize that life is the best thing and that you have no business taking it for granted.
It is so easy to waste our lives, our days, our hours, our minutes. It is so easy to exist instead of to live. I learned to live many years ago. Something really, really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all. And what I learned from it is what, today, seems to be the hardest lesson of all.
I learned to love the journey, not the destination. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally. And I tried to do that, in part, by telling others what I had learned. By telling them this: Read in the backyard with the sun on your face. Learn to be happy. And think of life as a deadly illness, because if you do, you will live it with joy and passion as it ought to be lived.
