Minding the Planet

Virtual Out of Body Experiences

A very cool experiment in virtual reality has shown it is possible to trick the mind into identifying with a virtual body:

Through these goggles, the volunteers could see a camera view of their own back - a three-dimensional "virtual own body" that appeared to be standing in front of them.

When the researchers stroked the back of the volunteer with a pen, the volunteer could see their virtual back being stroked either simultaneously or with a time lag.

The volunteers reported that the sensation seemed to be caused by the pen on their virtual back, rather than their real back, making them feel as if the virtual body was their own rather than a hologram.

Volunteers

Even when the camera was switched to film the back of a mannequin being stroked rather than their own back, the volunteers still reported feeling as if the virtual mannequin body was their own.

And when the researchers switched off the goggles, guided the volunteers back a few paces, and then asked them to walk back to where they had been standing, the volunteers overshot the target, returning nearer to the position of their "virtual self".

This has implications for next-generation video games and virtual reality. It also has interesting implications for consciousness studies in general.

Scientists Encode Message into Bacterial DNA

Japanese scientists have developed a technique that can encode 100-bit messages into the DNA of common bacteria. The bacteria replicate and pass the message down from generation to generation for at least thousands of years. Because there are millions or more copies of the message it can survive gradual degradation or mutuations (so they claim). Perhaps by taking a sample of the message across a large number of descendant bacteriums any errors or mutations can be detected and corrected. The message that was encoded was ""e=mc² 1905".

I've written about the potential of storing messages in DNA in the past here, and here.

What's interesting of course is that since this is possible it begs the question of whether there are already messages encoded into the DNA of various living things on Earth? We might want to look at E Coli, or other common organisms, or perhaps human, dolphin, and whale DNA. We might also want to look at birds and lizards since they come down more directly from dinosaurs. Who knows -- maybe a long long time ago someone left us messages there, or their signature at least.

There are two places that I think it is most likely that we will first receive messages from aliens, if we ever do:

1. Our own DNA (or that of other living species on Earth)
2. The Internet. It's the logical place to establish communication with us. Perhaps via a Myspace page...
   

Capturing Your Digital Life

Nice article in Scientific American about Gordon Bell's work at Microsoft Research on the MyLifeBits project. MyLifeBits provides one perspective on the not-too-far-off future in which all our information, and even some of our memories and experiences, are recorded and made available to us (and possibly to others) for posterity. This is a good application of the Semantic Web -- additional semantics within the dataset would provide many more dimensions to visualize, explore and search within, which would help to make the content more accessible and grokkable.

Cryotherapy -- Freeze Yourself, For Health

And now for some other science news. A new technique called cryotherapy is emerging in which people subject themselves to short bursts of extreme cold, in order to rejuvenate the body:

It's minus 120 degrees and all I'm wearing is a hat and socks. Cryotherapy is the latest treatment for a range of illnesses including arthritis, osteoporosis, and even MS. New Age madness or a genuine medical breakthrough?

Prelude

Many years ago, in the late 1980s, while I was still a college student, I visited my late grandfather, Peter F. Drucker, at his home in Claremont, California. He lived near the campus of Claremont College where he was a professor emeritus. On that particular day, I handed him a manuscript of a book I was trying to write, entitled, "Minding the Planet" about how the Internet would enable the evolution of higher forms of collective intelligence.

My grandfather read my manuscript and later that afternoon we sat together on the outside back porch and he said to me, "One thing is certain: Someday, you will write this book." We both knew that the manuscript I had handed him was not that book, a fact that was later verified when I tried to get it published. I gave up for a while and focused on college, where I was studying philosophy with a focus on artificial intelligence. And soon I started working in the fields of artificial intelligence and supercomputing at companies like Kurzweil, Thinking Machines, and Individual.

A few years later, I co-founded one of the early Web companies, EarthWeb, where among other things we built many of the first large commercial Websites and later helped to pioneer Java by creating several large knowledge-sharing communities for software developers. Along the way I continued to think about collective intelligence. EarthWeb and the first wave of the Web came and went. But this interest and vision continued to grow. In 2000 I started researching the necessary technologies to begin building a more intelligent Web. And eventually that led me to start my present company, Radar Networks, where we are now focused on enabling the next-generation of collective intelligence on the Web, using the new technologies of the Semantic Web. 

But ever since that day on the porch with my grandfather, I remembered what he said: "Someday, you will write this book." I've tried many times since then to write it. But it never came out the way I had hoped. So I tried again. Eventually I let go of the book form and created this weblog instead. And as many of my readers know, I've continued to write here about my observations and evolving understanding of this idea over the years. This article is my latest installment, and I think it's the first one that meets my own standards for what I really wanted to communicate. And so I dedicate this article to my grandfather, who inspired me to keep writing this, and who gave me his prediction that I would one day complete it.

This is an article about a new generation of technology that is sometimes called the Semantic Web, and which could also be called the Intelligent Web, or the global mind. But what is the Semantic Web, and why does it matter, and how does it enable collective intelligence? And where is this all headed? And what is the long-term far future going to be like? Is the global mind just science-fiction? Will a world that has a global mind be good place to live in, or will it be some kind of technological nightmare?

A Village Where Aging is Sped Up

Here's an interesting video about a village in India where men have been stricken for over a decade with a disease that causes them to age much faster. Nobody knows what is causing this. Men in their 30's appear to be 80. It's strange. Watch the video. Perhaps if someone were to collect some DNA and compare it to DNA of people without this syndrome a cure or at least an explanation could be found. This might also reveal what is different, if anything, about the DNA of people in this village that causes them to age -- and if a specific gene or set of genes is involved, this could perhaps provide a key to slowing down aging in healthy people.

Scientist Raises Possibility of Silicon-Based Life

Just read an interesting article on the possibility of "intraterrestrial" silicon-based life on Earth:

SETI spends enormous amounts of money and resources looking for life outside of Earth's realm, but life forms so alien that scientists may simply not have recognized evidence of their existence could inhabit the Earth, according to a leading scientist.

Dr Tom Gold, emeritus professor of astronomy at Cornell University in America, believes that organisms based on silicon - completely unrelated to all the carbon-based life man has encountered so far - may live at great depths.

In a forthcoming book he will suggest that scientists should take the possibility more seriously. Gold, who is a member of the Royal Society, previously predicted that vast amounts of more conventional bacteria live miles down within the Earth's crust. Scientists initially dismissed the idea, but many now agree with him.

"So long as nobody suspects there could be silicon-based life, we may just not be clever enough to identify it," he said last week.

Rocks bearing signs of silicon-based organisms may already be sitting in laboratories, he believes, with their significance overlooked.

Every known living organism, from bacteria to mankind, is based on the chemistry of carbon, which forms the complex molecules such as DNA that are central to our existence. Scientists believe that if extraterrestrial life is found, the chances are that it, too, will be carbon-based.

Editor's Note: While the prospect of silicon-based life is an interesting subject for further research, what the above scientists failed to note is that there is already a large population of Silicone-based life, particularly in Hollywood. Of course they probably can't get government funding to research THAT subject!                                                                                                                                                   

Neuro-Chips

Researchers continue to make progress in fusing living neurons with computer chips:

The line between living organisms and machines has just become a whole lot blurrier. European researchers have developed "neuro-chips" in which living brain cells and silicon circuits are coupled together.

The achievement could one day enable the creation of sophisticated neural prostheses to treat neurological disorders or the development of organic computers that crunch numbers using living neurons.

To create the neuro-chip, researchers squeezed more than 16,000 electronic transistors and hundreds of capacitors onto a silicon chip just 1 millimeter square in size.

They used special proteins found in the brain to glue brain cells, called neurons, onto the chip. However, the proteins acted as more than just a simple adhesive.

"They also provided the link between ionic channels of the neurons and semiconductor material in a way that neural electrical signals could be passed to the silicon chip," said study team member Stefano Vassanelli from the University of Padua in Italy.

The proteins allowed the neuro-chip's electronic components and its living cells to communicate with each other. Electrical signals from neurons were recorded using the chip's transistors, while the chip's capacitors were used to stimulate the neurons.

Big Thinkers' Most Dangerous Ideas

The Edge has published mini-essays by 119 "big thinkers" on their "most dangerous ideas" -- fun reading.

The history of science is replete with discoveries that were considered socially, morally, or emotionally dangerous in their time; the Copernican and Darwinian revolutions are the most obvious. What is your dangerous idea? An idea you think about (not necessarily one you originated) that is dangerous not because it is assumed to be false, but because it might be true?

 

Obsessed Tourist Marries Dolphin

Here's a happy story about true love. An Israeli millionaire tourist recently married a captive dolphin in a formal wedding ceremony. There's something fishy about this wedding though -- I mean did the dolphin really love her for HER, or did he just want her for her money? When asked to comment, the woman repeated that she is "not a pervert" -- PHEW! I'm glad she emphasized that point because otherwise I might have had my doubts. Anyway, what I really want to know is: was it a traditional Jewish wedding ceremony or not, and if it was, how did the dolphin crush the wine glass? Do they even let people bring glassware into the pool nowadays? I thought you could only bring plastic cups to the pool. What kind of operation are they running down there anyway? Well, if you ask me this marriage probably won't last: I think couples should live together for a while before getting married.
