Lightning implicated in ozone over Africa About five years ago, atmospheric scientists studying ozone concentrations over equatorial Africa and the southern hemisphere of the tropical Atlantic came across a puzzling situation. Unexpectedly high levels of ozone in southern Africa were finally explained by an overlooked phenomenon: lightning. |

Dwarfing Earth's Largest Dinosaur When compared to their counterparts today, animals and plants in the late Jurassic period, about 161 million to 145 million years ago, appear super-sized. Newly discovered dinosaur fossils show, however, that the largest animal to ever walk on Earth also came in a dwarfed version. |
