When the results of the research are controversial, it draws people's attention. This can lead to the field itself, like Embryonic Stem Cell and Obesity research becoming controversial. But controversial research can lead to more new developments as researchers strive to address the controversy with new solutions.

This article briefly looks at the physiological and some of the chemical processes and changes associated with sleep.

Astronomy has to be one the most humbling of all subjects to study. Just the thought of our universe, being like a grain of sand in a sandy shore of universes, is enough to make me want to crawl back under the sheets.
