Could the three established domains of life - eukaryotes, bacteria and archaea - be joined by a fourth?

Five years ago this week, the BBC started broadcasting one of the most extraordinary documentaries ever to grace television: Planet Earth. The culmination of five years of field work, it employed the most cutting-edge of techniques in order to capture life in all its forms, from sweeping spaceborne vistas to shockingly intimate close-ups -- including many sights rarely glimpsed by human eyes. Visually spectacular, it showcased footage shot in 204 locations in 62 countries, thoroughly documenting every biome from the snowy peaks of the Himalayas to the lifegiving waters of the Okavango Delta, a rich narrative tapestry backed by a stirring orchestral score from the BBC Concert Orchestra. Unfortunately, the series underwent some editorial changes for rebroadcast overseas. But now fans outside the UK can rejoice -- all eleven chapters of this epic story are available on YouTube in their original form: uncut, in glorious 1080p HD, and with the original narration by renowned naturalist Sir David Attenborough.

Dmitar Sasselov is an astrophysicist, Director of the Origins of Life Initiative at Harvard and a co-investigator of the Kepler space telescope project to find Earth-like planets around the Cygnus constellation and discover extraterrestrial life. But no matter how successful the Kepler project may be, it still won't answer the most fundamental questions of astrobiology: How diverse is life in the universe? If alien life exists, will it have Earthly DNA and proteins? Or will it run on something else? So Dr. Sasselov has decided to collaborate with two synthetic biologists, asking them to create a life form based on mirror-image versions of what we know as the essential building blocks of living things on Earth.

Researchers at MIT and in Korea have developed a new, efficient desalinization nanotechnology that could theoretically lead to small, portable units powered by solar cells or batteries, yet deliver enough potable fresh water from seawater to supply the needs of a family or small village. As an added bonus, the system would simultaneously remove many contaminants, viruses and bacteria. MIT Press Release. Abstract and Supplementary Information from Nature Nanotechnology.

How much life could you find in one cubic foot? With a 12-inch green metal-framed cube, photographer David Liittschwager (of the Endangered Species Project) surveyed biodiversity in land, water, tropical and temperate environments around the globe for National Geographic. At each locale he set down the cube and started watching, counting, and photographing with the help of his assistant and many biologists. The goal: to represent the creatures that lived in or moved through that space. The team then sorted through their habitat cubes and tallied every inhabitant, down to a size of about a millimeter.

"In Massachusetts, a young woman makes genetically modified E. coli in a closet she converted into a home lab. A part-time DJ in Berkeley, Calif., works in his attic to cultivate viruses extracted from sewage. In Seattle, a grad-school dropout wants to breed algae in a personal biology lab. These hobbyists represent a growing strain of geekdom known as biohacking, in which do-it-yourselfers tinker with the building blocks of life in the comfort of their own homes." They might be discovering cures for diseases or developing new biofuels, but are their experiments too risky? Via. [more inside]

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."

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.]

"We have [a substance] that extends the life of every species it's given to. We're 50 years ahead of where I thought we would be 10 years ago." While Harvard Medical School rules prevent David Sinclair from recommending product, "I know a number of scientists who think [it] is their best shot. Others satisfy themselves with a glass of red wine," which contains the compound. Too good to be true?
