LOS ANGELES, Calif., Feb. 1, 2006 -- UCLA paleobiologist J. William Schopf and colleagues have produced three-dimensional images of ancient fossils 650 million to 850 million years old and preserved in rocks, an achievement that has never been done before and which the scientists say could also be useful in trying to find signs of life on Mars. If a future space mission to Mars brings rocks back to Earth, Schopf said the techniques he has used -- confocal laser scanning microscopy and Raman spectroscopy -- could enable scientists to look at microscopic fossils inside the rocks to search for...Read full article
