"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]

Are plasma crystals alive? Cosmic dust can, in the presence of plasma, creates formations known as plasma crystals. An international team of researchers published a study in the Aug.14, 2007, issue of the New Journal of Physics (PDF here, abstract here) that indicates that these crystals may be more sophisticated than anyone realized. In simulations involving cosmic dust, the researchers witnessed the formation of plasma crystals displaying some of the elementary characteristics of life -- DNA-like structure, autonomous behavior, reproduction and evolution.

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?

Is life possible even in the coldest depths of space? If so, this tough little guy has long been thought to be a good candidate. Now, finally, analysis of the Tardigrades (a.k.a. "water bears") exposed to open space as part of the TARDIS project is finally complete. So what's the verdict? [more inside]

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?"

The Meaning of Life. "We create life, we search for it, we manipulate and revere it. Is it possible that we haven't yet defined the term (PDF)?" [Via The Loom.]

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.]

As the Pentagon ousts plans to turn insects into cyber war machines you'd be forgiven for asking the question: Where does the real digital end and the faked life begin? Are we simulating life synthetically? or just speeding up an entirely natural process? Technologically engineered life is here to stay. Its not far fetched to speculate that simulacra may become all there is.

The origin of life?! I heard from an authority in molecular biology today that a group of researchers funded by the Carnegie Institution and NASA believe they've discovered the origin of RNA, and with that, the origin of life.
This new discovery grew out of NASA's Deep Impact mission to study the composition of comets. Specifically, they started investigating a kind of carbon that forms in layers, with each layer slighly offset from the previous one in a helix shape. Significantly, the thickness of these carbon layers corresponds with the thickness of each twist in a strand of RNA.
It turns out that the individual building blocks of RNA are capable of bonding to this layered carbon when exposed to UV radiation. Once this has happened, apparently formaldehyde can then bond to the building blocks of RNA on the carbon "pattern", allowing the bonded RNA to slough off into the primordial soup. Over time, some of these RNA strands could fold and bond to themselves, forming DNA. Formaldehyde, the initial bonding material, would eventually be replaced by a more chemically sophisticated substance, creating the chemical bond that we observe today in DNA.
Expect a paper on it to be released in approximately three months with all the details.

"If time has to end, it can be described, instant by instant," Mr. Palomar thinks, "and each instant, when described, expands so that its end can no longer be seen." He decides that he will set himself to describing every instant of his life, and until he has described them all he will no longer think of being dead. At that moment he dies.
In memoriam of Italo Calvino, who died exactly 20 years ago.
"Calvino's novels" by his friend Gore Vidal. Calvino's obituary by Vidal, il maestro William Weaver's essay on Calvino's cities, Jeanette Winterson on Calvino's dream of being invisible, and Stefano Franchi's philosophical study on Palomar's doctrine of the void. More inside.

Did the discovery of evolution lead to Darwin's agnosticism, as claimed? Carl Zimmer wonders. More importantly, can evolution be reconciled with Christianity?

The Meaning of Life according to various rather famous people (Dennett, Fukuyama, etc). I'm watching the Dennett video at the moment and it starts rather weakly, but, by midway through, is rolling along nicely. With topics like "being good without god" and "the anthropic principle" it struck me as relevant to a couple of recent askmefi threads.
Dennett: [pause] i guess i'll say it again, more slowly...
