When administered in lethal levels, antibiotics trigger a fatal chain reaction within  bacteria that shreds the cell's DNA. But, when the level of antibiotic is less than lethal the same…

There is a presumption among many people that extraterrestrial life is a foregone conclusion and that it is only awaiting our discovery.  The Drake equation is usually highlighted as many…

In an article published this week in Science, Monash University biochemists say they have discovered the process by which bacteria developed into more complex cells and that this crucial evolutionary…

Go check out Carnival of Evolution # 20 at Skeptic Wonder. This month's issue includes a metagenomic analysis of the carnival submissions. (I get a fairly long phylogenetic branch of my own!) Go…
