Gaia Education Educators for a Sustainable Earth (the GEESE) flew from the 4 corners of the world into Thailand to meet in a beautiful, curvaceous mud building surrounded by lotus ponds and bamboo groves. Inspired by Ghandian ashrams where social change meets spiritual practice and working with the land, Wongsanit Ashram is a hub of sustainability and grassroots leadership training in South East Asia. Wongsanit is also an idyllic eco-settlement complete with organic gardens and traditional thatched and cob houses. This was a wonderful base to come together to discuss the Ecovillage Design Education (EDE). In keeping with the diversity of the group the Southerners revelled in the sultry, humid tropical days whilst Northerners were challenged by the heat! ... more »

...Oster argues that health is an investment. If you’re expecting to live a good, long time, you might be more inclined to make health investments than if you expect to die soon. If your life expectancy is only 40-50 years due to environmental factors, you might be more willing to take this 3% risk than a gay man in America who otherwise expects to live almost 80 years.
To test this effect, Oster looked at sexual behavior rates in countries that had high, low and medium levels of malaria. In countries with low malaria, there’s a very strong correlation between prevalence of AIDS and change in behavior - in countries with high malaria, there’s no correlation, or in fact, an opposite effect. There’s a similar correlation with maternal health and child mortality. This suggests that if you want to combat AIDS, you also need to deal with malaria, internal air quality and maternal health. ... more »

...So, climate negative. Any plan which doesn't measure itself against that bar is no plan at all. To get a sense of how difficult our task will be, take a look at the boldness and complexity of Energy [R]evolution, a blueprint for reducing global CO2 by 50% worldwide by 2050.
Cutting our CO2 in half, the authors say, will take major breakthroughs in solar, wind, geothermal, bioenergy, hydropower, and advanced fossil fuel technologies. It will take behavioral changes. It will take policy shifts, changing the way we tax energy and pollution and incentivize innovation and investment to level the playing field. And it will take proceeding on different paths in different places. It will be, in short, a massive undertaking. Now imagine that as a half step, and one that will come too late. Imagine not just radical change, but transformation. ... more »

...The first prize winner for 2007 is James Nachtwey, a remarkable war photographer who’s been described as a “one man human rights watch”. He’s been extensively honored for his work, winning numerous prizes for his work covering some of the most difficult images in the world.
He apologizes for using notes - “after spending an entire career trying to be invisible” speaking before a group is an “out of body” experience. The truth is, his images are so powerful and moving, I found it very hard to even follow his voice for much of his talk. As he said, “I have been a witness - these pictures are my testimony.” ... more »

The annual TED (Technology, Entertainment, & Design) conference in Monterey, CA, USA, brings together more than 1000 thought-leaders, movers and shakers for four days of learning, laughter and inspiration. -- The first TED in 1984 included the public unveiling of the Macintosh computer and the Sony compact disc, while mathematician Benoit Mandelbrot demonstrated how to map coastlines with his newly discovered fractals and AI guru Marvin Minsky outlined his powerful new model of the mind. Several influential members of the burgeoning 'digerati' community were also there, including Nicholas Negroponte and Stewart Brand.
Those who have spoken at TED include Bill Gates, Frank Gehry, Jane Goodall, Billy Graham, Herbie Hancock, Murray Gell-Mann, Larry Ellison. Yet often the real stars have been the unexpected: Li Lu, a key organizer of the Tiananmen Square student protest, Aimee Mullins, a Paralympics competitor who tried out a new pair of artificial legs on-stage, or Nathan Myrrhvold speaking not about Microsoft platforms, but about dinosaur sex. ... more »

Daniel Tammet is a high-functioning autistic savant. He can calculate huge sums in his head in seconds and instantaneously recognise prime numbers, but he finds emotions difficult to understand and has trouble telling left from right. One of fewer than fifty such people living worldwide, Daniel is unique in his ability to articulate his savant experience.
Daniel can also learn to speak a language fluently from scratch in a week. In the documentary "Brainman," he is challenged to learn a difficult new language - Icelandic - from scratch in just seven days, and then does a succesful interview in Reykjavik entirely in Icelandic. ... more » Thursday, March 8

...Sony Computer Entertainment' Phil Harrison officially opened the doors on "Home" for PS3. This unique avatar-based real-time virtual community will enter a large scale beta trial in April and the service itself (which will be found after a free download on the XMB) is scheduled to launch this fall.
...Game 1.0 was represented by the disconnected console and static game discs; Game 2.0 was brought to us by connected consoles (or PCs) that offered static content; but Game 3.0 takes connected consoles to a new level by leveraging online collaboration and user-generated content. Suddenly the content is dynamic and, as Sony says, Game 3.0 "puts the spotlight back on the consumer." Harrison explained that Sony was influenced by the ideas put forth by web 2.0 – sites such as MySpace and YouTube that are driven by user-generated content. Harrison also made clear that Sony is not trying to trademark Game 3.0; they simply want to get the developer and gaming communities thinking about a trend which Harrison believes "will power the next decade of growth in our industry." ... more » Wednesday, March 7

Last year, 161 exabytes of digital information were created and copied, according to research firm IDC. Can't get your mind around that number? That's understandable. Try this -- that amount of information is equal to three million times the amount of information in all the books ever written. It's also equal to 12 stacks of books, each extending the 93 million miles between the Earth and the sun. -- And it's only going to continue to grow exponentially. According to IDC, the amount of information created and copied in 2010 will surge more than six fold to 988 exabytes. That amounts to a compound annual growth rate of 57%. -- An exabyte is one quintillion bytes or a billion gigabytes...
The largest component of the digital universe, IDC said, will be images captured worldwide by more than 1 billion devices, from digital cameras to camera phones, medical scanners, and security cameras. The number of images captured on consumer digital still cameras in 2006 exceeded 150 billion worldwide, while the number of images captured on cell phones hit nearly 100 billion, IDC said. Digital photography by 2010 will capture more than 500 billion images... "This ever-growing mass of information is putting a considerable strain on the IT infrastructures we have in place today," said Mark Lewis, EMC executive VP and chief development officer, in a written statement. "This explosive growth will change the way organizations and IT professionals do their jobs, and the way we consumers use information." ... more » Thursday, March 1

On April 26, Dr. Hawking, surrounded by a medical entourage, is to take a zero-gravity ride out of Cape Canaveral on a so-called vomit comet, a padded aircraft that flies a roller-coaster trajectory to produce periods of weightlessness. He is getting his lift gratis, from the Zero Gravity Corporation, which has been flying thrill seekers on a special Boeing 727-200 since 2004 at $3,500 a trip.
Peter H. Diamandis, chief executive of Zero G, said that “the idea of giving the world’s expert on gravity the opportunity to experience zero gravity” was irresistible. In some ways, this is only a prelude. Dr. Hawking announced on his 65th birthday, in January, that he hoped to take a longer, higher flight in 2009 on a space plane being developed by Richard Branson’s company Virgin Galactic, which seeks to take six passengers to an altitude of 70 miles. ... more » Monday, February 26

Ray Kurzweil wrote this article as the introduction to James Gardner's new book, "The Intelligent Universe: AI, ET, and the Emerging Mind of the Cosmos." It's a good summary of Ray's latest thinking. Though its very techno-optimistic view is contrary to the post-modern skeptical flavor often presented on SCIY, I've been following Ray's thinking for years and continue to be impressed with his erudite scholarship. -- In any case, I believe it's an important function of SCIY to present viewpoints that are contrary to our own; to be skeptical of our own skepticism.
... It is remarkable to me that almost all of the discussions of cosmology fail to mention the role of intelligence. In the common cosmological view, intelligence is just a bit of froth, something interesting that happens on the sidelines of the great cosmic story. But in the standard view, whether the universe winds up or down, ends up in fire (a great crunch and new Big Bang), or ice (an ever-expanding and ultimately dead universe), or something in-between, depends only on measures of dark matter, dark energy, and other parameters we have yet to discover. That the story of the universe is a story yet to be written by the intelligence it will spawn is almost never mentioned. This book will help to change the common "unintelligent" view. So what will we do when our intelligence is in the range of a google (10^100) cps? One thing we may do is to engineer new universes. Similarly, our universe may be the creation of some superintelligences in another universe. In this case, there was an intelligent designer of our universe--that designer would be the evolved intelligence of some other universe that created ours. Perhaps our universe is a science fair experiment of a student in another universe. (Reading the news of the day, you might get the impression that this erstwhile adolescent superintelligence who designed our universe is not going to get a very good grade on his or her project.) But the evolution of intelligence here on Earth is actually going very well. All of the vagaries (and tragedies) of human history, such as two world wars, the cold war, the great depression, and other notable events, did not make even the slightest dent in the ongoing exponential progressions I previously mentioned. ... more » Thursday, February 22

...We do not yet know what makes some systems more adaptable than others, but research on complexity has yielded some clues. Some of my own work on physical systems called spin glasses suggests that the level of central control over subsidiary parts of a system is an important consideration. Too much control freezes the system into limited configurations; too little causes it to wander aimlessly. Only systems that hover on the border between order and chaos exhibit the needed general stability and capacity to explore the universe of possible solutions to challenges.
The path to maximum prosperity will depend on finding ways to build economic systems in which new niches will generate spontaneously and abundantly. Such an approach to economics is indeed radical. It is based on the emergent behavior of systems rather than on the reductive study of them. It defies conventional mathematical treatments because it is not prestatable and is nonalgorithmic. Not surprisingly, most economists have so far resisted these ideas. Yet there can be little doubt that learning to apply these lessons from biology to technology will usher in a remarkable era of innovation and growth. ... more » Tuesday, February 20

NORFOLK, Va. -- At the Naval Network Warfare Command here, U.S. cyber defenders track and investigate hundreds of suspicious events each day. But the predominant threat comes from Chinese hackers, who are constantly waging all-out warfare against Defense Department networks, Netwarcom officials said. - Attacks coming from China, probably with government support, far outstrip other attackers in terms of volume, proficiency and sophistication, said a senior Netwarcom official, who spoke to reporters on background Feb 12. The conflict has reached the level of a campaign-style, force-on-force engagement, he said.
“They will exploit anything and everything,” the senior official said, referring to the Chinese hackers’ strategy. And although it is impossible to confirm the involvement of China’s government, the attacks are so deliberate, “it’s hard to believe it’s not government-driven,” the official said. - The motives of Chinese hackers run the gamut, including technology theft, intelligence gathering, exfiltration, research on DOD operations and the creation of dormant presences in DOD networks for future action, the official said. ... more » Sunday, February 18

Scientists have developed a new technique for species identification - a DNA barcode. Similar to the barcodes that identify consumer products, species barcodes identify unique animals or plants. - Now, taking the use of DNA barcoding to a more complex level, an international team of scientists reports assembling a barcoded genetic portrait of bird life in the United States and Canada - the prelude to a genetic portrait of all animal life on Earth.
Based on DNA barcode identifiers, the scientists have discovered 15 new genetically distinct species, nearly indistinguishable to human eyes and ears and thus overlooked in centuries of bird studies. ... more » Friday, February 16

The next known close encounter with an asteroid will occur, somewhat ominously, on Friday the 13th of April 2029. Then, Near-Earth Object 99942--also known as Apophis (Greek for "The Demon of Darkness")--is expected to miss the planet by a mere 30,000 kilometers. The real sweating begins soon after, when astronomers must determine whether Earth's gravity has steered Apophis onto a course for impact seven years later. ... more »

This is an unusually long article for SCIY. It's copyrighted by Eric M. Weiss, and was his dissertation for his Ph.D. at CIIS, the California Institute of Integral Studies, with a concentration in Philosophy, Cosmology and Consciousness. I'm taking the liberty of posting it here because, in my opinion, it's one of the most thorough and insightful treatments of the core concern of SCIY; the multiple & interpenetrating relationships between science, culture, and consciousness, placed within the contextual framework of Sri Aurobindo's Integral Yoga. - Warning: This is challenging material, but I believe working through it and contemplating its implications is well worth the effort. - My deepest appreciation goes to Dr. Eric Weiss for his extraordinary and groundbreaking work. ~ ron
...Here we are, at the dawn of the Twenty First Century, and I have awakened to find myself living in a science fiction novel. If this novel were to be written from the standpoint of the 23rd century, looking back to the beginning of the 21st, it might start something like this: At that time, the certainties of science had faltered. The great charism of the men in white lab coats had faded. The bastions of materialism had crumbled from within, and the civilization that it had fostered was losing its way. Meanwhile, three centuries of rapacious assault on the biosphere were, at last, showing decisive results. The globe was poisoned, people were sick, species were being slaughtered by the tens of thousands, global temperatures and global sea levels were both beginning to rise. A civilization was ending, and in its death throes, it was bringing to a close the Cenozoic Era. The Earth was preparing for a fresh creation. Looking back, too, we can see that the promise of the new civilization had already begun to shine. The iron cage of the material world, in which the species had been trapped for centuries, was starting to dissolve. Here and there, the experiences of the subtle worlds were breaking through. A few intrepid explorers had seen the promise, and had just begun to glimpse the vast freedoms and the limitless horizons that we now enjoy, but the darkness was still thick and Kali was dancing wildly across the face of the globe. This is the story of those early pioneers… more » Sunday, February 11

A mysterious illness is killing tens of thousands of honeybee colonies across the country, threatening honey production, the livelihood of beekeepers and possibly crops that need bees for pollination.
Researchers are scrambling to find the cause of the ailment, called Colony Collapse Disorder. Reports of unusual colony deaths have come from at least 22 states. Some affected commercial beekeepers _ who often keep thousands of colonies _ have reported losing more than 50 percent of their bees. ... more » Wednesday, February 7

This is Part 1 of a series of quoted passages from the book The Field: the Quest for the Secret Force of the Universe, by science journalist Lynn McTaggart. It’s an excellent non-technical explanation about the metaphysical implications of modern quantum theory, especially what’s called the ‘Zero Point Field.’ I hope this can provide a useful vocabulary for our ongoing dialogues re possible relationships between science and spirituality. I’ll say more in future comments to these articles. ~ ron
...The notion of an electromagnetic field is simply a convenient abstraction invented by scientists (and represented by lines of 'force', indicated by direction and shape) to try to make sense of the seemingly remarkable actions of electricity and magnetism and their ability to influence objects at a distance — and, technically, into infinity — with no detectable substance or matter in between. Simply put, a field is a region of influence. As one pair of researchers aptly described it: 'Every time you use your toaster, the fields around it perturb charged particles in the farthest galaxies ever so slightly.' ... In the quantum world, quantum fields are not mediated by forces but by exchange of energy, which is constantly redistributed in a dynamic pattern. This constant exchange is an intrinsic property of particles, so that even 'real' particles are nothing more than a little knot of energy which briefly emerges and disappears back into the underlying field. According to quantum field theory, the individual entity is transient and insubstantial. Particles cannot be separated from the empty space around them. Einstein himself recognized that matter itself was 'extremely intense' — a disturbance, in a sense, of perfect randomness — and that the only fundamental reality was the underlying entity — the field itself. ... The Zero Point Field is a repository of all fields and all ground energy states and all virtual particles — a field of fields. ... The existence of the Zero Point Field implied that all matter in the universe was interconnected by waves, which are spread out through time and space and can carry on to infinity, tying one part of the universe to every other part. The idea of the Zero Point Field might just offer a scientific explanation for many metaphysical notions, such as the Chinese belief in the life force, or qi, described in ancient texts as something akin to an energy field. It even echoed the Old Testament's account of God's first dictum: 'Let there be light', out of which matter was created. ... If all subatomic matter in the world is interacting constantly with this ambient ground-state energy field, the subatomic waves of the Zero Point Field are constantly imprinting a record of the shape of everything. As the harbinger and imprinter of all wavelengths and all frequencies, the Zero Point Field is a kind of shadow of the universe for all time, a mirror image and record of everything that ever was. In a sense, the vacuum is the beginning and the end of everything in the universe. ... If that were true, it meant every part of the universe could be in touch with every other part instantaneously. ... ... If matter wasn't stable, but an essential element in an underlying ambient, random sea of energy ... then it should be possible to use this as a blank matrix on which coherent patterns could be written, particularly as the Zero Point Field had imprinted everything that ever happened in the world through wave interference encoding. This kind of information might account for coherent particle and field structures. But there might also be an ascending ladder of other possible information structures, perhaps coherent fields around living organisms, or maybe this acts a a non-biochemical 'memory' in the universe. It might even be possible to organize these fluctuations somehow through an act of will. ... this represented nothing less than a unifying concept of the universe, which showed that everything was in some sort of connection and balance with the rest of the cosmos. The universe's very currency might be learned information, as imprinted upon this fluid, mutable field of information. The Zero Point Field demonstrated that the real currency of the universe — the very reason for its stability — is an exchange of energy. If we were all connected through the Zero Point Field, then it just might be possible to tap into this vast reservoir of energy information and extract information from it. With such a vast energy bank to be harnessed, virtually anything was possible — that is, if human beings had some sort of quantum structure allowing them access to it. But there was the stumbling block. That would require that our bodies operated according to the laws of the quantum world. ... more » Wednesday, January 31

A toxic purple haze of diesel exhaust hangs over the rice and jute fields here in northeastern India, and bird songs are frequently drowned out by the chug-a-chug-a-chug of diesel generators. — Across the developing world, cheap diesel generators from China have become a favorite way to provide electricity. — They power everything from irrigation pumps to television sets, allowing growing numbers of rural villages in many poor countries to grow more crops and connect to the wider world. — But as the demand increases for the electricity that makes those advances possible, it is often being met through the dirtiest, most inefficient means, creating pollution in many remote areas that used to have pristine air and negligible emissions of carbon dioxide and other global warming gases...
Another popular approach being tried in India and elsewhere -- using solar energy to recharge lanterns by day -- has run into difficulty even as diesel prices would seem to make it more competitive. — The problem is that prices for photovoltaic panels for solar energy have surged as governments in industrialized countries, especially Germany, have encouraged greater use of renewable energy, said Hemant Lamba, the coordinator of Aurore, a renewable energy service company in Auroville, India. — "It's harder to do any solar energy projects in India," he said. ... more »

Selvi Alagappan rises early each day to tend to her small patch of crossandra and jasmine flowers in the rural Indian village of Mangalam, in the Union of Pondicherry. These and the mushrooms she cultivates in a nearby shack bring in a monthly income that, while still below the poverty line, keeps her large family from going hungry. — Two years ago, however, starvation was very much a reality for Selvi and her family. But like many other participants of the Biovillage Project, a collaborative development programme described by its authors as "pro-nature, pro-women, pro-poor", Selvi was given the tools and technical assistance to increase her household income and get her back on her feet again.
The project is run by the M.S. Swaminathan Research Foundation, a local non-governmental organization in Chennai, with funding and technical assistance from the Government of India and international agencies including FAO, the United Nations Development Programme (UNDP) and the International Fund for Agricultural Development (IFAD). The project began in 1992 with 42 participants in three villages. It now operates in 19 villages with a team of 24 project specialists. ... more »

The United Nations (UN) has been recommended to set up a Statutory Body comprising G8 and G20 nations to provide political oversight to the global and national efforts to achieve the goal of a hunger-free world by 2015. — The recommendation was made in the Chennai Declaration that was adopted yesterday on the concluding day of the three-day international workshop on "Food Security: A Great Threat to Human Security" held at the MS Swaminathan Research Foundation (MSRRF) in Chennai in India.
"The goal should be eradication of hunger by 2015, and not halving the proportion or the number of the hungry in relation to any chosen base year," the declaration recommended. — It said all the member states of the UN should make the right to a balance diet, clean drinking water, environmental sanitation, primary health care and primary education a basic human right... The programme will be completed today (Thursday) through visiting Biovillage and Auroville, a MSSRF project in Pondicherry. ... more »

I started reading this interview with more than a little skepticism. ("Oh, this must be one of Bush's Christian fundamentalist appointees.") But as I read through it, I became increasingly impressed with the balanced perspective held by Dr. Collins. I'm posting it here because I think it provides an encouraging example of a possible rapprochement between scientists and people of faith.
The media often portray the religious right in the United States as antiscience. Is that a fair characterization? I don't think it's fair to blame believers for getting defensive about attacks on the Bible when they see their whole belief system is under attack from some members of the scientific community who are using the platform of science to say, "We don't need God anymore, that was all superstition, and you guys should get over it." Believers then feel some requirement to respond, and this has led to an unfortunate escalation of charges and countercharges... So what would you say to the scientists who are fervently opposed to religious thought and practice? Is there any dogma more unsupported by the facts than from the scientist who stands up and says, "I know there is no God"? Science is woefully unsuited to ask the question of God in the first place. So give the religious folks a break. They are seeking the kind of spiritual truths that have always interested humankind but that science cannot really address. ... more » Tuesday, January 30

This is one of the best summaries of the science of climate change and global warming forecasting I've seen. It's by Kerry Emanuel, a professor of meteorology at MIT, who was recognized in 2006 by Time magazine as "one of the world’s 100 most influential people." Highly recommended.
...The evolution of the scientific debate about anthropogenic climate change illustrates both the value of skepticism and the pitfalls of partisanship... general awareness of the issue dates to a National Academy of Sciences report in 1979 that warned that doubling CO2 content might lead to a three-to-eight-degree increase in global average temperature. Then, in 1988, James Hansen, the director of NASA’s Goddard Institute for Space Studies, set off a firestorm of controversy by testifying before Congress that he was virtually certain that a global-warming signal had emerged from the background climate variability... Most scientists were deeply skeptical of Hansen’s claims; I certainly was... At roughly this time, radical environmental groups and a handful of scientists influenced by them leapt into the fray with rather obvious ulterior motives. This jump-started the politicization of the issue, and conservative groups, financed by auto makers and big oil, responded with counterattacks... A very small number of climate scientists adopted dogmatic positions and in so doing lost credibility among the vast majority who remained committed to an unbiased search for answers... On the right, the search began for negative feedbacks that would counter increasing greenhouse gases: imaginative ideas emerged, but they have largely failed the acid test of comparison to observations. But as the dogmatists grew increasingly alienated from the scientific mainstream, they were embraced by political groups and journalists, who thrust them into the limelight. This produced a gross distortion in the public perception of the scientific debate. Ever eager for the drama of competing dogmas, the media largely ignored mainstream scientists whose hesitations did not make good copy. As the global-warming signal continues to emerge, this soap opera is kept alive by a dwindling number of deniers constantly tapped for interviews by journalists who pretend to look for balance... more » |
