- This "Roman Tech" episode illustrates a myriad of innovations the Romans developed before us: bikinis, strengthened concrete, sports arenas, central heating, window glass, double-paned windows, bathrooms, aqueducts providing clean tap water for a million citizens, sophisticated road systems, multi-story block apartments, surgical instruments, anesthetics and high-tech medical facilities.
- Earth's magnetosphere, which shields us from deadly solar radiation is decaying rapidly. When it collapses, as Mars's did billions of years ago, Earth will be stripped of its atmosphere, water and life. This episode explores new evidence that the Earth's magnetic poles are on the verge of reversing. As it does, Earth's magnetosphere will weaken greatly for thousands of years, allowing solar radiation to penetrate to the Earth's surface. This will threaten many species, including man, with extinction. In 2010 three satellites will be launched to detect minute variations in field strength and identify any new areas of pole reversal. For mankind to survive, we must develop technological methods of protecting ourselves before this happens.
- Scientists reveal evidence of the existence of alien life. Detailed imaging of an underground ocean on a planetary moon and newly discovered extrasolar planets reveal what contacting alien life will be like. This is a serious scientific look at how will we meet ET.
- Iceland's Eyjafjallajokull volcano erupted April 14, 2010, spewing aircraft-harming ash over most of Europe. It could cause Katla, its neighboring, larger volcano to erupt. NGC looks at Eyjafjallajokull before, during and after, explaining the science behind the chaos and the biggest disruption of air traffic since 9/11.
