Sometimes the need to escape the heat and humidity of a D.C. summer can be taken to extremes. Witness a decision made by a pair of scientists to summer in Antarctica. (OK, so 'summer' on the frozen continent goes from November through February. You caught us.)

The scientists are with the Smithsonian Institution and their work ranges from studying climate and meteorites, to researching the very origin of the universe. And even though they're back in D.C. as Andrew Hiller reports, the memory of their trip continues to keep them cool.
