It is hard to predict how science is going to turn out , and if it is really good science, it is impossible to predict. If the things to be found are actually new, they must be unknown in advance You cannot make choices on this matter. You either have science or you don't and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits.
The only solid piece of scientific truth about which I feel totally confident is that we don’t know enough about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, a clear piece of news. It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange seems the way ahead . In earlier times, they either pretended to understand how things worked or simply made up stones to give answers. Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered. Because of this, we are sorry. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.
But we are making a beginning, and there ought to he some satisfaction. There are probably no questions we can think up that can’t he answered, sooner or later. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, arid pay attention.

After their 20-year-old son hanged himself during his winter break from the University of Arizona five years ago, Donna and Phil Satow wondered what signs they have overlooked, and started asking other students for answers.
What grew from this soul searching was Ulifeline (www. Ulifeline. org), a Web site where students can get answers to questions about depression by logging on through their universities. The site has been adopted as a resource by over 120 colleges, which can customize it with local information, and over 1.3 million students have logged on with their college ID’s.
“It is a very solid Web site that raises awareness of suicide, de-stigmatizes mental illness and encourages people to seek the help they need,”said Paul Grayson, the director of counseling services at New York University, which started using the service nearly a year ago.
The main component of the Web site is the Self-screening program developed by Duke University Medical Center that tests students to determine whether they are at risk for depression, suicide and disorders like anorexia and drug dependences. Besides helping students, the services compiles anonymous student date, offering administrators an important window onto the mental health of its campus.
The site provides university users with links to local mental health services, a catalog of information on prescription drugs and side effects, and access to Go Ask Alice, a vast archive developed by Columbia University with hundreds of responses to anonymously posted inquires from college students worldwide. For students concerned about their friends, there is a section that describes warning signs for suicidal behavior and depression.
Yet it is hard to determine how effective the service is. The anonymity of the online service can even play out as a negative. “There is no substitute for personal interaction(个人互动才能解决)，” said Dr. Lanny Berman, executive director of the American Association of Suicidology, based in Washington.
Ulifeline would be the first to say that its service is no replacement for an actual therapist. “The purpose is to find out if there are signs of depression and then direct people to the right places,” said Ron Gibori, executive director of Ulifeline.
Mrs. Satow, who is still involved with Ulifeline, called it “a knowledge base” that might have prevented the death of her son, Jed. “If Jed’s friends had known the signs of depression, they might have seen something,” she said.
