[单项选择]High Stress May Damage Memory
According to a report issued in May 1998, elderly people who have consistently high blood levels of cortisol don’t score as well on memory tests as their peers with lower levels of the stress hormone. What’s more, high levels of cortisol are also associated with shrinking of the hippocampus, a region of the brain that plays a key role in learning and memory.

America’s genius with high technology may have put men on the moon, but there is growing skepticism (怀疑) about its ability to solve human problems closer to home.
In fact, a subtle but significant shift from purely technological solutions is already underway as scientists argue openly for new directions in research.
A growing number of scientists insist that answers to the world’s problems will not come from a flashier array of electronics and machines. Instead, as they see it, solutions must evolve from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential of the earth’s resources.
What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.
More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.
