Tasty New Mammal Family

Scientists have created the first new mammal family since 1974, when the bumblebee bat was discovered. Say hello to the southeast asian rock rat, laonastes aenigmamus, a previously undiscovered rodent which is said to resemble a cross between a rat and a squirrel, but which is in fact a fairly distant relative of any other currently living rodent.

So what kind of intensive field work led to this amazing discovery? Years of turning over rocks and cutting through Asian thicket, no doubt.

Well, not exactly.

Biologist Robert Timmins reports that he stumbled across the rock rat on sale as a snack food in Laos.

Sometimes the process of discovery can only be described as delicious. I’m not quite sure whether this is one of those times.

Radical Evolution: A Book Review

I managed to get my hands on an advanced copy of Joel Garreau’s Radical Evolution : The Promise and Peril of Enhancing Our Minds, Our Bodies — and What It Means to Be Human. If you like reading about the things we write about here, Garreau’s book is easily the best to cover these topics since Kurzweil’s Age of Spiritual Machines. Order it today. It’s that good.

Not that I agree with all of Garreau’s thoughts here. After outlining the possible technologies that the future may bring (what he calls the GRIN technologies – genetics, robotics, information, and nano-tech), he divides his book into several sections: Heaven, Hell, and Prevail. His idea is that there are some people – Ray Kurzweil being the most prominent – that see nothing but “Heaven” ahead. Others, like Leon Kass, see every new development as a harbinger of coming dystopia – the “Hell” scenario.

Then Garreau outlines a scenario that he obviously leans toward – “Prevail.” In the Prevail scenario we will advance with the same “two-steps-forward, one-step-back” rhythm that we’ve always experienced. New technologies will bring new problems that will be solved, as we’re able.

Heaven, Hell, and Prevail make for nice clean divisions in a book, but I don’t think that Kurzweil (or we Speculists) can be so easily pigeonholed as utopians. Even Leon Kass might be less of a dystopian in reality than he is portrayed here. Instead, almost all people who consider the future would accept some form of Garreau’s idea of Prevail. Prevail is really a sliding scale with Heaven at one extreme and Hell at the other.

No doubt The Speculist falls on the optimistic half of that spectrum. We believe that our accelerating development will provide more solutions than problems. We’re Billy Joel futurists:

‘Cause the good ole days weren’t
Always good
And tomorrow ain’t as bad as it seems

But that isn’t “Heaven.”

Enough nitpicking…Radical Evolution is a gold mine of information about coming technology. I especially enjoyed the section on DARPA. Just a quick example: Garreau mentions DARPA’s “Unconventional Pathogen Countermeasures” program. The goal of this project is to create super-soldiers that are resistant to all disease.

The object of the game is to discover the essential part of life common to many of these pathogens…and interrupt them. An example would be finding an enzyme that appears only in bacteria, but not in us… Another [method of attacking disease in general] is “genomic glue” – something that sticks onto the genome of the pathogen so tightly that it prevents the genome from being read…

How far along is DARPA in the development of this kind of wonder drug? The interview subject wouldn’t say, but there is this tantalizing clue:

The nice part, so far, is that the bugs have not been able to develop resistance to the treatment no matter how hard the researchers have tried to induce it.

Radical Evolution is thick with this sort of reporting. This one is not to be missed. Look for it May 17, 2005.

The Green Reformation

In the current issue of MIT’s Technology Review, Stewart Brand goes on record with a rather startling prediction:

Over the next ten years, I predict, the mainstream of the environmental movement will reverse its opinion and activism in four major areas: population growth, urbani­zation, genetically engineered organisms, and nuclear power.

I certainly hope Brand is right about the coming shift. Clearly, the environmental movement is on the wrong side of history with each of these issues. No matter how we play with the numbers, it’s now undeniable that the population explosion has ended, with some population numbers gaining momentum in the opposite direction. Urbanization is good for the environment because it centralizes populations, creating more room for species-preserving habitat. Genetically engineered crops produce better yields and make fewer demands on natural resources. Unlike the fossil fuels we currently use to power our energy grid, nuclear power does not pollute the air or water. Moreover, nuclear power provides the most plausible scenario for enabling the eventual use of hydrogen as a fuel for cars.

So it would seem that logic alone dictates that the environmental movement make these changes. But according to Brand, logic is only part of the equation:

Reversals of this sort have occurred before. Wildfire went from universal menace in mid-20th century to honored natural force and forestry tool now, from “Only you can prevent forest fires!” to let-burn policies and prescribed fires for understory management. The structure of such reversals reveals a hidden strength in the environmental movement and explains why it is likely to keep on growing in influence from decade to decade and perhaps century to century.

The success of the environmental movement is driven by two powerful forces—romanticism and science—that are often in opposition. The romantics identify with natural systems; the scientists study natural systems. The romantics are moralistic, rebellious against the perceived dominant power, and combative against any who appear to stray from the true path. They hate to admit mistakes or change direction. The scientists are ethicalistic, rebellious against any perceived dominant paradigm, and combative against each other. For them, admitting mistakes is what science is.

I finally got around to seeing Luther a couple of weeks ago. The film presents a similar dichotomy to the one Brand describes, with the scholarly Luther challenging the dominant paradigm of the dogmatic church hierarchy. The movie doesn’t have a lot of time to spend on the counter-reformation which eventually ocurred, wherein the Catholic church cleaned up its own act on many of the isssues which had initially led Luther to rebel. But I think what Brand is describing, 10 years down the road, is a counter-reformation within the environmental movement.

Before there can be a counter-reformation, however, won’t there first have to be a protestant reformation? Won’t some of these scholarly, ethicalistic scientists have to break with Rome over the central issue of authority?

No, not the papacy.

I was thinking more like global warming.

In his article, I note that Brand does not challenge the received wisdom concerning global warming in any way. In fact, his major argument for nuclear power is the benefit it will provide in combating global warming.

But then again, Luther dedicated his first book on papal indulgences to the pope himself. The story is just beginning.

Plant More Rice!

Many people are afraid of our accelerating future. I doubt that the name for our destination – “The Technological Singularity” – helps relieve any fear. There’s something sinister-sounding about any singularity, but this is a black hole in our timeline. You don’t have to be especially prone to worry for this to cause concern

In some ways “Singularity” is the perfect name. It accurately represents our ability to predict the future at some point – perhaps after super intelligence arrives. But for glass-half-full guys like me, the Singularity is less a falling to zero than an explosion in personal power – more life, more liberty, and more happiness.

The engine powering all this is exponential increases in computation. This is a trend commonly called Moore’s Law. Moore’s Law states that the size of each transistor on an integrated circuit chip will be reduced by 50 percent every twenty-four months. The result is the exponentially growing power of integrated circuit-based computation over time. Moore’s Law doubles the number of components on a chip as well as the speed of each component while price remains roughly constant.

dozen doublings.JPGRay Kurzweil takes a broader view of this trend. Computation via the integrated circuit is just the latest paradigm that goes back to the arrival of RNA, if not before.

Wherever you place the starting line, the effect of exponential doubling is mind boggling. Here’s a graph showing the effect of twelve doublings. Each step forward is equal to all the progress of the past in just one unit of time. Phil has illustrated the power of this trend with an old parable:

A prince wanted to reward the inventor of chess for the wonderful new game. So the inventor asked for one grain of rice for the first square on the chessboard, two grains for the second, four for the third square and so on doubling for each square.

[The prince] dispatched one of his stewards to fulfill the order. It took the steward a while to report back, and when he did the news was not good. Although harvest was just completed, the gift was going to completely exhaust the royal granaries. And they were only on the 40th square!

In fact, it turns out that if you were to keep doubling until you reached the 64th square, you would have an amount of rice greater than the total yield of every rice crop in the history of the planet earth.

3d graph.JPGAs remarkable as this story is, it fails to capture the full power of the trends we are experiencing. We aren’t just getting better computers. The exponential improvements in computation are fueling exponential trends in all areas of technology. To picture this we have to add a z-axis to our graph.

Our civilization is playing the rice game on Mr. Spock’s chessboard! Advancement on the computation board buys our way onto new boards: nanotech, genetic engineering, life extension, self-replicating universal constructors, etc. Advancement on the new boards can further fuel the progress of any other board or create new boards. It’s an explosion of knowledge in all directions.

Domesticated Bacteria

Lord Broers, the President of England’s Royal Academy of Engineering, recently said, “Our experience with chemistry and physics teaches us that we do not have any idea how to make an autonomous self-replicating machine at any scale.”

Broers didn’t say that autonomous self-replicating machines are impossible. Still, this caused a bit of a stir over at Howard Lovy’s Nanobot blog where K. Eric Drexler responded (in part):

It is a pity that Lord Broers has joined the parade of denialists who discuss distorted versions of obsolete scenarios to the exclusion of all research in the field since 1990.

This problem – self-replicating machines – is being approached from multiple directions. Adrian Bowyer is working on macro-scale self-replicating machines. Howard Lovy’s blog points to a multitude of scientists working on nano-scale inorganic machines. And we’ve recently had some important news from microbiologists. A team led by Ron Weiss at Princeton University has demonstrated the ability to command bacteria to form complex shapes and even colors. This is done through DNA instructions.

050428_bacteria_bullseye_02.jpgWeiss and his colleagues engineer a special segment of DNA, the blueprints for any cell’s operations. The segment is called a plasmid.

“You have a segment of DNA that dictates when proteins should be made and under what conditions,” Weiss told LiveScience. The plasmid is inserted into a cell, and “the cell then executes the set of instructions.”

These pictures show two of Weiss’ bacterial formations – a bullseye and a heart. Weiss believes that this technology could be quickly adapted to detect bioterrorism chemicals. The bacteria could literally form a bullseye around an anthrax microbe.

Long-term applications are even more interesting. Weiss has also shown the feasibility of making bacteria act like networked computers.

050428_bacteria_heart_02.jpgThe cells, for example, could be made to perform basic mathematical logic and produce crisp, reliable readouts that are more commonly associated with silicon chips than biological organisms…

The creation of patterns, such as the bull’s-eye effect, is a key step in one of Weiss’ eventual goals, which is to have the cells secrete materials that build physical devices such as antennas or transmitters in places that are hard for humans to reach. Programmed cells also could be used to control the repair or construction of tissues within the body, possibly guiding stem cells to the locations where they are needed for the growth of new nerve or bone cells in a process Weiss called “programmed tissue engineering.”

Imagine biological cyborgs – people with networked cells traveling throughout the body with programmed instructions to fix problems. An external server that looks like a nicotine patch could control this activity.

It’s true that we have much to learn about autonomous self-replicating machines. Engineered bacteria may dominate the early years of nanotech. There’s a precedent: the horse was domesticated before we built a car.

Live To See It

Last year Phil wrote a post entitled “Death Sucks.” No argument here. It does. But for some reason there’s no shortage of people who ask, “Why would you want to live indefinitely?”

Aubrey de Grey thinks it’s a fair question, but he has a good answer. You don’t have to decide today to live 1000 years. If life is rewarding now, you probably don’t want to die today. Chances are you’ll still be in no hurry to die if 100 years from now life is still rewarding. You may still feel the same in 1000 years. This is also an answer to those who might not want life extension. De Grey is not arguing for mandatory immortality. He’s arguing against mandatory age-related death.

In his book, “More Than Human,” Ramez Naam had another thought. He argued that we shouldn’t consider life extension technologies in isolation from other transformative technologies:

When we contemplate the three years that a mouse may live, we don’t mourn its short time on this earth. In three years, a mouse lives and learns as much as it’s able, and more years wouldn’t add meaning or quality to its life. Today a human life span may provide enough years for a man or woman to learn and grow as much as we’re able. But in the decades to come, we’ll increase our capacity to learn, grow, and change over time. Eventually one hundred years may seem like a brief adolescence…

More Than Human – page 126

I think we could continue to find life rewarding for many more years even with current mental limitations. It’s not life that gets old. It’s the getting old that gets old. As the body fades it takes more effort to reach diminishing goals. Little wonder that the elderly grow nostalgic for “the good old days.” They may not have had indoor plumbing, but their body’s plumbing worked great.

People also get bored with their jobs. It might not make financial sense to retrain late in a career – particularly if age will affect job prospects after retraining. But an ageless workforce wouldn’t be stuck like that. You could work for a time, take a sabbatical (in lieu of permanent retirement), retrain, and then work in a new position.

I suspect, though, that Naam is correct. If we understand the human body well enough to fix a problem as complex as aging, what’s to keep us from enhancing the body as well? Given the option, most of us would choose to be smarter, stronger, more agile, and resistant to toxins and disease. We would want sharper vision and better hearing. We would like to eat what we want without adding pounds.

We may be within 25 years of real treatment for aging. We will see advancements in all of these other areas in the interim. Beyond that…all bets are off.

Live to see it!
