revolution: the right kind and the wrong kind

carolynbaker | Lately I've been encountering articles and news stories touting the need for revolution in the wake of a gansterized U.S. financial system and a government that has itself become a criminal enterprise. I sense that many bloggers and their readers are salivating with anticipation that someone or something will light the fuse of a revolutionary cannon that will eviscerate the present system and replace it with something more just and humane.

I share their enthusiasm for profound, bone-marrow transformation of the status quo. Jefferson really was right when he proclaimed that the United States needed a revolution every twenty years. Many of us who were activists during the Vietnam War era were determined to pull off a revolution that would destroy the military industrial complex, institutionalized racism, and the entire capitalist agenda.

Today's visionaries and activists cherish similar hopes, yet I fear that they do not yet grasp the kind of revolution that the planet seems to be asking for. And unlike the revolution we envisioned four decades ago, this one must be in response to the planet and the earth community. From this perspective, I believe there are two kinds of revolution in front of us: The kind that is inappropriate and the kind that is both useful and critical for planetary survival.

Inappropriate Revolutions
The most truly inappropriate revolution would be one based on false assumptions, principally, the notion that political change on a grand scale is meaningful. Pundits of this kind of revolution include all cheerleaders for the Democratic Party and all others who champion the Progressive, left-liberal landscape. These folks are currently obsessing about the November election and agonizing over Tea Party cacophonies. From this perspective, if the far-right were resoundingly defeated by the election of liberal candidates, the nation might be spared from spiraling downward into fascism.

Other well-meaning but naïve proponents of revolution argue that social upheaval and more people in the streets will signal enough distress among the population to provide fertile ground for a political and cultural revolution. While not directly advocating the overthrow of the federal government, these individuals are poised to organize and assume positions of leadership should sufficient unrest unfold.

Inappropriate revolutions tend to focus on widespread global (whether literal or symbolic) measures that will result in mass consciousness raising, mass movements, and mass political and cultural change. This philosophy mirrors "bigger is better" and assumes that significant change only happens when society at large is involved. Models of this kind of revolution in the modern era would be ones such as the Russian Revolution, the Maoist revolution in China, and the Cuban Revolution.

Such revolutions rarely address the emotional and spiritual aspects of social change because for the most part, the possibility that any force greater than the human mind and ego exists is rejected out of hand. A revolution operating from this assumption is by definition, human-centric. Whereas political revolutions may include individuals who care deeply about the ecosystems and argue passionately for stewardship of the earth, their agenda is not fundamentally informed by the earth. Man is still the measure of all things and therefore, given the desired political context, humans can reverse their species' destruction of the planet and engineer something approximating utopia.

So what is an appropriate revolution? And appropriate to what, you may ask.

Appropriate Revolutions
An appropriate revolution is one that is relevant to what is actually needed in the light of human and planetary evolution. It is not primarily political but rather informed by what the earth community is asking for. For example, the earth is not asking for more efficient and accessible healthcare. Rather, it is asking that humans live in such conscious intimacy with the earth that nearly all of humanity's diseases and injuries are prevented as a result of that relationship.

Likewise, the earth is not asking for renewable energy but a cellular level transformation of consciousness regarding how we live on the earth-how we eat, what we wear, the products we use, where we live, where we travel and how.

The earth is not asking for jobs, but rather a painfully honest examination of our purpose in walking on her body in terms of the work that is most beneficial for her and all species that inhabit the planet.

The earth is asking, no pleading, for inhabitants who are willing and eager to live and relate locally in small communities, cooperating with neighbors to replenish what has been stolen from the earth and to enhance the well being of all species.

earlier start to multicellular life

The Scientist | Newly uncovered fossils hint that multicellular life may have evolved more than 2 billion years ago -- some 200 million years earlier than previously expected, according to a study published this week in Nature.

The fossils are "not really [what] you expect to find in the rock record 2 billion years before present," said paleontologist Philip Donoghue of the University of Bristol, who was not involved in the research. "These fossils are centimeters in size" and "relatively thick" -- too large to be just a single cell, he said.

The once-biological shapes carved out of black shale formations in Africa outdate the next oldest example of what may have been multicellular life by about 200 million years. Unfortunately, "there's nothing preserved inside," said Donoghue, who wrote an accompanying perspective. "You can't demonstrate [for sure] that it was multicellular [because] you can't see component cells."

Sedimentologist Abderrazak El Albani of the University of Poitiers in France and his colleagues discovered the amorphous fossils in the black shale formations of the Francevillian Basin in Gabon, Africa. The team found more than 250 specimens at the site, all dating to approximately 2.1 billion years ago, and ranging up to 12 centimeters in length. Chemical analyses confirmed the biological origin of the fossils, which are now composed of the iron-sulfide mineral pyrite that replaced the organic tissue as the organism decomposed. And their large and complex structures, as revealed through X-ray microtomography, are indicative of cell-to-cell signaling and coordinated growth between cells, El Albani said.

Specifically, the fossils display scalloped edges with radiating slits, and many have a central structure, not unlike the overall structure of a jellyfish medusa. "This organism, in my opinion, was something very light, very gentle, very soft," El Albani speculated. Given the ubiquity of the radial structures among the highly diverse specimens, "I am sure that this radial fabric has some functionality for these specimens," he said, possibly for movement or fixation to the sediment, but "we have a lot of work [to do]" to determine what that function truly was. Still, the complexity and organization of their structure "shows clearly that [these organisms were] multicellular," he insisted.

But to call these fossils multicellular, it's important to first define multicellularity, Donoghue told The Scientist. "There are a great number of definitions, some of which are very restrictive and others which are all encompassing." Part of the difficulty in defining the term, he added, is that "much of the molecular machinery that is necessary for cell-to-cell communication is" found even in more primitive organisms, such as bacterial colonies.

Interestingly, these fossils appear just a couple million years after the Great Oxidation Event, when oxygen became more widely available in the atmosphere and in the shallow oceans. This may have facilitated the evolution of a thicker organism, where "it becomes more difficult for the cells in the middle to obtain that oxygen if it's only at trace levels in the atmosphere," Donoghue said.

old bonobos just nasty......,

Reuters | Disease risk higher for swingers than prostitutes. Scientists studying swingers -- straight couples who regularly swap sexual partners and indulge in group sex at organized meeting -- say they have higher rates of sexually transmitted infections (STIs) than prostitutes. Dutch researchers publishing their work in the British Medical Journal showed that older swingers -- those over the age of 45 -- are particularly vulnerable and yet are a group largely ignored by healthcare services.

With estimates that the swinger population could be many millions across the world, the scientists said there was a risk this untreated group could act as an STI "transmission bridge to the entire population."

"Although exact estimates are unavailable, the swingers' population is probably large," wrote Anne-Marie Niekamp, who worked on the study with colleagues from Maastricht University.

The Dutch study analyzed the numbers of patients seeking treatment in 2007 and 2008 at three sexual health clinics in South Limburg in the Netherlands.

The clinics have recorded whether a patient is a swinger since the start of 2007, in an attempt to track infection rates among this group.

During the study period, there were just under 9,000 consultations at the three clinics. One in nine of the patients was a swinger, with an average age of 43.

Overall, combined rates of Chlamydia and gonorrhea were just over 10 percent among straight people, 14 percent among gay men, just under 5 percent in female prostitutes, and 10.4 percent among swingers, they found. And female swingers had higher infection rates than male swingers.

One in 10 older swingers had Chlamydia and around one in 20 had gonorrhea.

Chlamydia is the most common sexually transmitted disease among women and in 70 percent of cases causes no symptoms. The bacterial infection can lead to pelvic inflammatory disease, ectopic pregnancy and infertility. Gonorrhea is another bacterial infection which can also lead to infertility if left untreated.

Niekamp said that while other high risk groups, such as young straight people, gay men and prostitutes, were relatively easy for healthcare service to identify and target for advice and help, swingers were generally a hidden community.

"That makes them very hard to reach," she said in a telephone interview. "Because they are so hidden and in some ways also stigmatized, it is hard for them to come forward for STI testing and treatment."
