Blue eyed Adam

by Alexander Rose - Twitter: @zander on February 4th, 02008

Genetic Archeology (very cool site in its own right) is reporting new research that suggests that all blue eyed people stem from a common ancestor 6-10,000 years ago.
“They have all inherited the same switch at exactly the same spot in their DNA” says Professor Eiberg.  Brown-eyed individuals, by contrast, have considerable. . .   Read More

Man made life progresses…

by Alexander Rose - Twitter: @zander on January 24th, 02008

Wired and Reuters are reporting on the latest work by Craig Venter published in Science this week. Venter’s synthetic life program completed the second of three steps in creating a synthetic organism.
“We consider this the second in our three-step process to create the first synthetic organism,” said J. Craig Venter, president of. . .   Read More

DNA Driven World

by Alexander Rose - Twitter: @zander on December 20th, 02007

This BBC lecture was posted by Edge.org and I thought it would be a good preparation for our upcoming February 25th talk by Craig Venter. Some excerpts:
To begin the process of change we need to start with our children by teaching them in place of memorization, to explore, challenge, and problem solve in. . .   Read More

We are those mutants.

by Austin Brown on December 10th, 02007

The Human Exemptionalism (or sometimes ‘Exceptionalism’) Paradigm is the idea that humans are somehow separate from nature or that we have transcended it in some way through spirituality, technology or consciousness. It is a paradigm that is shared between many of the religious ideologies of the world as well as many devotees of science and. . .   Read More

Whole Earth Comes Into Focus

by Alexander Rose - Twitter: @zander on December 7th, 02007

 Our own Stewart Brand has an essay in the current issue of Nature (subscription required) on integrating two disparate disciplines in order to solve our worlds largest problems.

To understand how our planet uses energy, we must integrate genetic data from microbial studies with satellite views of our planet.
Two vastly different but complementary projects. . .   Read More

On the 8th day, Venter creates life

by Alexander Rose - Twitter: @zander on October 19th, 02007

Genes of micro-organisms are being modified to create something new
 
The BBC reports on our upcoming seminar speaker Craig Venter’s recent advances in creating life. Attendees of Juan Enriquez’ illuminating talk “Mapping Life” also heard about this research and Venter’s success in “jump starting” life by injecting DNA from one cell. . .   Read More

Juan Enriquez “Mapping Life”

by Stewart Brand on October 13th, 02007

Mapping Life

“All life is imperfectly transmitted code,” Enriquez began, “and it is promiscuous.” Thus discoveries like the one last month of an entire bacterial genome inside the DNA of a fruitfly is exploding the old tree-of-life models of evolution. The emerging map replaces gene lineages with gene webs.

“There is a whole. . .   Read More

Genetic diversity on the decline…

by Alexander Rose - Twitter: @zander on August 8th, 02007

By studying mitochondrial DNA from samples over 1000 years old to the present, scientists have good evidence that human genetic diverstiy is on the decline. You can see the article from the Royal Society here (a great source of many forms of long term science in general).
“In a study covering five different periods of. . .   Read More

Philip Longman – “The Depopulation Problem”

by Stewart Brand on August 17th, 02004

The depopulation problem

No need to summarize this time. Phillip Longman wrote out his whole talk, with the illustrations more viewable even than they were at the Seminar and talk.

It is full of rethink-the-news sentences like: “Notice that Japan’s lengthening recession began just as continuously falling fertility rates at last caused. . .   Read More
