  • Last year a dull star suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star has long since faded back to obscurity, but observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" have uncovered remarkable new features.

    The Nuclear Heart of Planet Earth
    Brisbane - Mar 31, 2003
    What would we find if we were to dig a hole all the way down to the centre of the Earth? According to high school science books we would discover a liquid iron alloy core and a smaller solid inner core at the center. For ten years, geophysicist J. Marvin Herndon has presented increasingly persuasive evidence that at the very centre of the Earth, within the inner core, there exists a five mile in diameter sphere of uranium which acts as a natural nuclear reactor. In this extended interview Wayne Smith talks with Dr Herndon about this theory and its implications for planetary science.

    America Not Prepared for Bio-Terror
    San Antonio - Mar 31, 2003
    One would think, after the many months of debate and evaluation by the experts, that all of the major concerns about the United States smallpox protection plan presently being implemented, would have been resolved. However, at last count seven weeks into stage one (of three stages), only about 17,000 individuals (3.7 percent of the goal) have been vaccinated writes Saul B. Wilen.
