The history of the field of microbiology may not be as long as other scientific areas, but it's just as interesting. After 100 years in print the Journal of Bacteriology is taking, what you might say, a walk down memory lane. It's highlighting the top 100 historical papers over the last century in its "Classic Spotlight" series.

What's more, dark beer is packed with beneficial free iron. And that's also why beer should have been included in the recently-issued nutritional guidelines.
