Terry talks with New Yorker writer John Seabrook about the downside of electronic mail. Then she gets a response from Stewart Brand, the inventor of The Well, a computer conference system. . . Last January Seabrook wrote an article in the New Yorker magazine about Microsoft chairman, Bill Gates. Seabrook was flooded with electronic mail as a result, and to his surprise he was "flamed" for the first time. In Internet jargon, to be "flamed" is to receive an obscene or derogatory E-mail message. Seabrook said he'd never received anything like it before.

Retired Astronaut and former test pilot Alan Shepard. He was America's first man in space in 1961; the voyage covered 302 miles and lasted 15 minutes. Ten years later with Apollo 14, he made it to the moon, playing golf on the moon's surface. (In 1969, the Apollo 11 landed on the moon, and Neil Armstrong was the first man to set foot on the moon). Early in his space career, Shepard was diagnosed with an inner ear syndrome which could have ended his career. Shepard grounded himself in 1963 and became Chief of the Astronaut Office.

Today it was announced that scientists had unearthed in Ethiopia the first nearly complete skull of the earliest recognized human ancestors. It's that of a male who lived three million years ago, giving a face to the species first identified in 1974 with the discovery of the skeleton named "Lucy." Paleoanthropologist Donald Johanson discovered Lucy and was part of the team to make this new discovery. The discovery could settle the debate of whether various fossils from this time period were from a single species, Australopithecus afarensis, or from different species.

Physicist James Trefil. His new book, "A Scientist in the City," (Doubleday) is a exploration of how the laws of nature and technology came together to make our cities. Trefil starts by looking at cities as natural ecosystems, and then looks at the key scientific discoveries that made cities possible. Trefil has written more than ten books on science, including, "1001 Things Everyone Should Know About Science." Trefil is also a regular commentator for NPR, and he teaches at George Mason University.

Astrophysicist George Smoot. Since 1974 he's worked on NASA's Cosmic Background Explorer (COBE) satellite, leading the instrument team that detected cosmic "seeds." In 1992 he announced that he and a team of researchers had detected the biggest, oldest objects ever observed in the universe, the "cosmic seeds" that were the origin of galaxies and clusters of galaxies.

Writer Howard Rheingold. In his newest book, "The Virtual Community: Homesteading on the Electronic Frontier" (Addison- Wesley) he argues that although computer mediated communication has made it possible for people to have access to almost anything, it is dangerous as well. Rheingold says individuals must keep using the internet as a way to express their views or they will loose the ability to do so, as the government and large corporations become more aware of the technology's capabilities.

Dr. Paul Mayewski, chief scientist with the Greenland Ice Sheet Project 2. The project archives tubes of ice extracted from Greenland which chronicle 250,000 years of the earth's atmosphere, and changes in the climate. From the ice, scientists can pinpoint the start of the industrial revolution, or the end of the ice age. Scientists hope, by looking at the ice, they can better understand rapid changes in the earth's climate. (Interview by Marty Moss-Coane)
