Analyzing the Ring of Life

Molecular biologists have uprooted a traditional perspective on life's ancient ancestry, if their supplanted tree-of-life metaphor is modified to look more like a ring-of-life.    Astrobiology Magazine -- One of science's most popular metaphors - the "tree of life," with its evolutionary branches and roots, showing groups of bacteria on the bottom and multicellular animals on the higher branches - turns out to be a misnomer, UCLA molecular biologists report in the Sept...

Zeno of Elea famously postulated his many paradoxes in defence of Parmenides' worldview: that all is "oneness," and pluralism is merely an illusion.    Of his forty paradoxes, the four most enduring have fascinated philosophers, mathematicians, and regular pundits for millennia.    As one of the many pundits ensnared by Zeno's challenges, I will present my own analysis of arguably his most famous paradox of all: The race between Achilles and the tortoise.

JACKSON HOLE, Wyoming -- There is mounting evidence of the role of water  in Mars' evolution. That fact appears to have been favorable to the  development of life -- and the leftover calling card of past biology may be  preserved in that world's geologic record.

"Rubinius is a project to watch", so says Charles Nutter in his post Rite, Rubinius, and Everything &mdash; I think he's right.  Evan is hard at work making things work better in rubinius.  He's now got continuations working (I think this makes him the first alternative implementation of Ruby to do so), and says he should have serializable continuations soon (see his post on it here).  W00t!

The complexity of life took    billions of years to push and stretch and reshape the biological niche that    is Earth. It would seem prudent Â if one had the means Â to save some portion    of the blueprints of this majesty, so that the process would not have to start    over from scratch in the event of a global cataclysm.
