Sparks of Life. "That the electric 'spark of life' figured prominently in debates over the nature of life in the late eighteenth and early nineteenth centuries is well known. Less well known is the fact that prior to this period, gunpowder was often identified with the substances that were necessary to life, if not as a vitalistic spirit, then as an essential element in the animation of the body. The idea of a spark of life went back to ancient times, likening living beings to the glowing embers of a fire. In the Old Testament, for example, the wise woman of Tekoah begs for the life of her son, pleading 'they will stamp out my last live ember.' But from the sixteenth to the eighteenth century, this vital flame was often equated with gunpowder. There was fire in the blood: not electric, but pyrotechnic fire."
Source Of Geysers On Saturn's Moon Enceladus May Be Underground Water. Earlier this year the Cassini spacecraft detected organic material in the geysers of Enceladus. The question now is, how's the fishing?
Festooning The Tree Of Life. Carl Zimmer describes new research on lateral gene transfer which makes the Tree of Life look more like a Gordian Knot.
Suspending Life. "If almost every species on Earth was killed some 250 million years ago, how did our ancient ancestors survive and evolve into us?"

In Games, an Insight Into the Rules of Evolution. Carl Zimmer writes about Martin Nowak (previously mentioned here), a mathematical biologist who uses games to understand how cooperation evolved. [Via MindHacks.]
The Encyclopedia of Life project will create a compendium of every aspect of the biosphere. It aims to compile data on all of Earth's 1.8 million known species on one Web site, and will include species descriptions, pictures, maps, videos, sound, sightings by amateurs, and links to entire genomes and scientific journal papers. E. O. Wilson is getting his wish. [Via BB.]
The Shape of Life is a new PBS series produced by the Sea Studios Foundation.
