What’s with the ‘God’ Angle?

A startling headline, no doubt:

Self-assembling computer circuits, who needs God?

And a pretty amazing story to go with it:

On a cross between physics, chemistry, biology and what some could possibly call blasphemy, European scientists have developed a self-assembling integrated circuit, an important step towards the ultimate goal: self-assembling computers.

According to Geoff Brumfiel in Nature, a team of European physicists has developed an integrated circuit that can build itself. Today, the building of computer chips is slowly pushed to the limit. Computer chips are made by etching patterns onto wafers made of semiconductors. The details of these patterns are no more than a few tens of nanometres. For us humans, it is nearly impossible to realize how small this is. There are 1,000 millimetres in one metre (25.4 in one inch), there are 1,000 micrometres in one millimetre and there are 1,000 nanometres in one micrometre. In other words, there are 1 billion nanometres in a metre or one million in a millimetre. Current technology is really getting to the limit, therefore other methods have to be found.

Dago de Leeuw, a researcher at Philips Research Laboratories in Eindhoven, the Netherlands, thinks that the most obvious solution is to let these circuits build themselves. We know that this is possible, since nature is chock-full of self-assembling machines: microbes, plants and animals, including humans. This is done via our genetic code that steers the entire process. In order to create truly self-assembling computers, scientists must come up with an entire new but similar system that would be able to get insulators, conductors and semiconductors to automatically link to each other. According to de Leeuw, this is still a long way off.

Nevertheless, the team has made a first step, and as usual, the first steps are the hardest ones to take. They took quinquethiophene, a long organic molecule with mobile electrons that acts like a semiconductor. They attached it to a long carbon chain, terminated by a silicon group. The silicon group acts as an anchor.

They then took a circuit board with preprinted electrodes and immersed it in a solution of these new molecules. Billions of molecules hooked on to an insulating layer between the electrodes. As a result, they formed connections through which a current could flow.

“The different molecules are like little bricks,” says Edsger Smits, another researcher at Philips. “Frankly it worked much better than we expected.”

But then come to think of it, I don’t really see how that headline, or the article’s opening sentence, go with the story at all. Self-assembling machines aren’t considered blasphemous in any religion I’ve ever heard of. I suppose there might be some nature religions which take offense at all machines and which therefore might consider a self-assembling machine to be particularly egregious.

But then shouldn’t the headline read, “Who Needs a Goddess?”

I guess the reporter needed a hook, and wanted to come up with something more original than the standard “The machines are taking over” line.

I suppose we should be grateful for that. Still, he might consider another really fresh approach: simply reporting positive developments as positive developments. It could work.

Life Finds a Way

This is pretty interesting:

An organism that was discovered in a South African gold mine, nearly 3km beneath the Earth’s surface, has scientists “buzzing with excitement” because it offers fascinating evidence that life could exist on other planets, say reports.

A community of the organisms was found by researchers in water extracted from a rock fissure in the Mponeng gold mine on the Witwatersrand near Johannesburg.

The rod-shaped bacterium, named Desulforudis audaxviator, exists in total darkness, with no oxygen and in 60°C heat. But, most importantly, it is the first known species to live in isolation in its own ecosystem, say researchers in a report by the Lawrence Berkley National Laboratory in California, one of a number of institutions involved in the research.

Certainly provides an interesting follow-up to this story, doesn’t it? If life can exist in such harsh conditions on this planet, it’s hard to rule it out altogether in a lot of hostile environments.

Creating Happiness

Here’s Martin Selgiman of the University of Pennsylvania with some thoughts on how happiness can be achieved. Selgiman has done extensive research into the effects of optimism on levels of performance and satisfaction in life.He argues here that psychology can’t just be focused on treating misery. It needs to take a positive approach that emphasizes pleasure, meaning, and flow. He concludes by arguing that technology (as well as entertainment and design) need to be re-tooled to achieve the same ends.

Better All The Time #38


Dispatches from a rapidly changing, rapidly improving world

10/16/2008

There’s a lot of bleak news out there, but let’s not let that blind us
to the good news. There is as much of it as ever — more in fact. This week
alone we have four good news stories about energy, hope for cancer treatment
from an unlikely source, confirmation of the power of the unconscious mind,
an "extinct" flower that’s back from oblivion, a cute robot that
might help usher in the next stage of evolution, and proof that smart guys
are sexier than jocks! Now what were you saying about the economy?

The Power of Unconscious Thought: Does It Result in Creative Problem-Solving?

No doubt many of us have all experienced a situation where, after long hours
of trying to solve a certain problem, we give up, and go get a break, only
to come back and solve the problem within moments. This appears to be a somewhat
commonplace situation. However, the science behind it is much more complex.

According to the authors of the study – Professor Adam Galinsky of the
Kellogg School of Management, Chen-Bo Zhong from the University of Toronto
and Ap Dijkstererhuis of Radboud University Nijmegen – unconscious thought
results in creative problem-solving in a two step process.

But this is not as simple as having an “Aha!” moment and moving
on. The trio note that while the distraction might be helpful in coming up
with the solution, a period of steady thought must follow so as to understand
the solution and how those solutions can be applied. Similarly, while such
moments might be useful in dealing with particularly tricky problems, easier
problems should be confronted the old fashion way.

The Good News

The research seems to show that conscious thought is better at solving straightforward
analytical problems, while unconscious thought gives a boost for solving more
complex problems. Clearly, we need a combination of both. But when faced with
a truly complex problem, it turns out that tendency to avoid thinking about
it might actually help.

Sometimes, anyway. But when in doubt…think.

Anything Into Ethanol

Biofuels could be a crucial weapon against both rising temperatures and dwindling
global oil supplies. They are made from organic material such as plants, so
they essentially recycle existing carbon in the atmosphere instead of releasing
new carbon from the depths of the earth; they are also, in principle, endlessly
renewable. But the best-known biofuel, ethanol, is looking decidedly unpromising
right now. Today most ethanol in the United States is made from corn, using
an energy-intensive process that may not actually save a lot of fossil fuel,
and in any case America cannot produce enough ethanol from corn to really
matter.

Scientists have long tried to devise an efficient way to make ethanol from
a wider range of raw materials, especially waste products rather than food.
The U.S. government has calculated that the country could generate 1.4 billion
tons of biomass a year. This could make 100 billion gallons of fuel or more,
enough to meet much of America’s demand for motor gasoline. One approach
to tapping into all that biomass focuses on cellulose, the material that gives
plant cells their strong walls. The cellulose is converted into sugar and
then from sugar into ethanol. But despite decades of research, the technology
is still far from commercially viable.

Now several companies, including Coskata and Range Fuels, say they have cracked
the problem. They are pursuing a different strategy, one that turns any carbon-rich
matter into a gas, which is then converted to liquid fuel. This approach can
use any organic material, so the potential sources for this fuel are virtually
unlimited. Soon, the companies claim, they will be able to refine vast quantities
of noncorn ethanol. Coskata even predicts they will do so for as little as
$1 a gallon.

The Good News

The article goes on to estimate that there is enough biomass in the southeastern
US alone to produce 15 billion gallons of fuel per year. Assuming that Americans
average about 500 gallons of gasoline each per year, and assuming that a gallon
of ethanol provides about 75% of the power that would come from a gallon of
gasoline, this biomass could meet the fuel needs of approximately 21 million
Americans, roughly 7% of us.

Plus, if the estimates above are anywhere near accurate, at $1.00 a gallon
— even providing quite a bit less energy per gallon than gasoline — this approach
would save us quite a bit of money. In fact, if that estimate is two times as
optimistic as it should be, and the ethanol would cost $2.00 a gallon to produce,
even accounting for the difference in energy provided and allowing for a reasonable
markup, we would be looking at the equivalent of $3.00 – $3.25 for a gallon
of gas. Not too shabby, even in these days of falling gas prices.

Nerds rejoice: Braininess boosts likelihood of sex

Lonely men ought to flaunt their copies of New Scientist. Women looking for
both one-night stands and long-term relationships go for geniuses over dumb
jocks, according to a new study of hundreds of university students.

"Women want the best of both worlds. Not only a physically attractive
man, but somebody in the long term who can provide for them," says Mark
Prokosch, an evolutionary psychologist at Elon University in North Carolina,
who led the study.

To many women, a smart man will appeal because he is likely to be clever
enough to keep his family afloat. But he may also pass on "good"
genes to his children, say Prokosch and his colleagues at the University of
California, Davis.

The Good News

Interestingly, these findings were based not on simply asking women what they
would prefer hypothetically, but by showing them videos of men alternatively
playing Frisbee, reading news reports, and talking about the possibility of
life on Mars. The guys who were rated as the most intelligent were also rated
as the sexiest.

Imagine that: men who talk convincingly about the possibility of life on Mars
are sexier than men who display athletic ability.

The Downside

Sorry ladies. These
guys
are taken. But, hey, if you want to listen in and dream, that’s okay.
There’s nothing wrong with that.

World’s First 100% Renewable Jet Fuel is Created

The EERC is leading the way to proving a pathway to energy security in the
United States by achieved a major technical milestone in creating a 100% renewable
domestic fuel that meets the JP-8 aviation fuel screening criteria.

The EERC fuel was produced under a $4.7 million contract with the US Department
of Defense’s Defense Advanced Research Projects Agency (DARPA). The Department
of Defense is the largest consumer of petroleum in America, and securing a
domestic fuel source is a key operational challenge for the military. Production
is now under way to produce a large fuel sample for engine testing this fall.

The Good News

The quoted article goes on to explain that this new fuel is made from "various
crop oils and waste greases." I thought it was pretty cool a while back
to learn that Daryl Hannah was running a Cadillac off fuel made from french-fry
grease
. That’s pretty cool, no doubt. But how much more cool if she
was flying one of these babies…

Rare Plant Thought Extinct Re-discovered in Upstate New York

A salt-marsh plant thought to have vanished from upstate New York is back.
But it has not come back to the inland salt marshes, of which only four remain
(three in New York and one in Michigan). Rather, the rare goldenrod was found
growing alongside local streets, probably competing well where run-off from
winter road salt suppresses other plant life. The species was discovered serendipitously
by Dr. Leonardo of the SUNY College of Environmental Science and Forestry
(ESF) as he was out walking.

"They’re coming out of asphalt, with no soil anywhere," Leopold
is quoted in an article in Syracuse. "And it’s striking because they’re
all blooming right now. It’s a visually spectacular plant." But the seaside
goldenrod’s beauty is not alone among it’s benefits to humanity and the environment.

The Good News

What’s great about this story is not only the good news that the seaside goldenrod
is still with us, but the wonderful adaptability that life on this planet can
display. No salt marshes available for habitat? Forget about it. This hardy
flower decides just to shoot up through the asphalt.

Furthermore

At The Speculist, we take an unusual stance on extinctions. Of course we think
they’re bad news. Terrible, in fact. It’s the Speculist view that we should
be doing all that we can to preserve our planet’s biodiversity and take what
steps are needed to prevent extinctions of animal and plant species from occurring.

So far, so good. But that sounds like everybody else’s view of extinctions,
doesn’t it?

Where we differ is in our belief that extinctions — while terrible and to
be avoided — are not the end of the story. We believe that advanced biotechnology
and nanotechnology will enable us one day to recover lost species. That doesn’t
mean that it’s okay to allow species to die out today, any more than it’s okay
to allow someone to go into preventable cardiac arrest because we can always
whip out the paddles and try to shock that heart into beating again. But it
does mean that there is hope that we will one day restore many species that
have been lost and are being lost now.

Solar Paint on Steel Could Generate Renewable Energy Soon

In three years, buildings covered in steel sheets could be generating large
amounts of solar electricity, thanks to a new photovoltaic paint that is being
developed in a commercial partnership between UK university researchers and
the steel industry.

A laboratory built to develop the new solar technology that replicates plant’s
photosynthesis is due to start work on October 30th in Shotton, North Wales.

The Good News

So we can grind up wood chips to power our cars
and we can use solar-steel buildings to power the electric grid. There certainly
does seem to be a wide range of options for how we might deal with our energy
problems. They don’t all have to work. A few select ones can make a huge difference.

Gut Microbe Strikes Again: Ulcer-Causing Bug May Also Prevent Cancer

The common ulcer-causing bug linked this summer to reduced rates of childhood
asthma and allergies may also help protect adults against one type of cancer,
according to a new analysis. Researchers report today in the journal Cancer
Prevention Research that they found the stomach microbe Helicobacter pylori
(H. pylori) may help prevent a major form of cancer of the esophagus (the
muscular tube that carries food and drink from the throat to the stomach).

The Good News

In the US alone, esophageal cancer kills nearly 15,000 people
each year. Any hope for prevention or treatment of this disease is, of course,
a wonderful thing. What makes this story especially wonderful is the source
of the hope. A bug that causes ulcers can help fight childhood allergies and
esophageal cancer. What’s next? A potato virus that cures
Alzheimer’s disease?

Prometheus Demonstrates Solar-Powered Electric Motorcycle

This past weekend, Prometheus Solar founder Jim Corning demonstrated his
proof-of-concept electric motorcycle at the Santa Monica AltCar Expo. The
motorcycle is a reconstructed Ninja 250 that uses four solar panels which
provide 800 watts of power.

The panels aren’t actually attached to the bike. Instead, they are left
out in the sun and connected to the bike’s 4.6 kW Thundersky lithium-ion
phosphate batteries for power storage. The front wheel cover and extended
back keep the motorcycle upright and aerodynamic.

And the bike isn’t exactly slow— Corning’s motorcycle can
go up to 70 MPH and has a range of 50 miles.

Corning currently has no plans to sell the bike, but perhaps interest in
the prototype will persuade him to look into mass production.

The Good News

Getting 70 mph on sun power is not too shabby. They need to work on that range,
of course, and the gimmick of having it come with its own solar panels is just
that. A more scalable solution will be an electric motorcycle that runs off
the grid, whether that power is solar, nuclear, hydrogen, whatever.

Still. Looks cool, doesn’t it?

Toy Robot Intended to Save Humans From Evil, Future Bots

When roboticist David Hanson thinks of the future, he fears that
man will accidentally create a super-sentient artificial intelligence that is
heartless and clinically insane.

So to save the world, he formed Hanson Robotics and built Zeno, a 17-inch
robot boy, who smiles, laughs, recognizes your face and remembers your name.

The Good News

We have written many times on the Speculist that one of the keys to a positive
future unfolding is the development of friendly artificial intelligence, not
only because of all the wonderful benefits that friendly AI will bring, but
because it is our best defense against unfriendly AI.

David Hanson puts it this way:

We want to be damn sure that by the time [robots] become as smart as we are,
they have a conscience and compassion and that we are friends. There’s no
guarantee. They could be psychotic.

Obviously, we need to take whatever steps are necessary to avoid that. Artificial
intelligence needs to be friendly. And if it’s cute, that’s just a bonus.

Better All The Time was compiled by Phil Bowermaster. Live to see it!

What's in a Name?

Phil and I spent some time Sunday night talking about various technogies that we think will have a profound impact on the future. We mentioned the space elevator, nuclear fusion, a universal assembler, cure for aging, and friendly artificial general intelligence.

Seemingly endless possibilities make predicting the future a fool’s game. But we play the game anyway here at the Speculist and on FastForward Radio because its just that fun.

With all the possibilities and uncertainty about the future it is surprising that there is a broad consensus amoung futurists about what technologies will be most important in shaping the future:

  • Nanotechnology,

  • Biotechnology,
  • Information technology, and
  • Cognitive science

Each of these four areas have the potential to cause a profound disruption in the way we do things today. And all four areas interact and build on one another in an exponential process I’ve called “Spock’s Chessboard.”

The combination of these emerging and converging technologies really should have a single accepted name. But as of right now, there are at least five competing acronyms. The prosaic “NBIC” (the four technologies listed in the above order) seems to have some official standing because it was used in a report sponsored by the US National Science Foundation.

Joel Garreau used “GRIN” (genetics, robotics, information tech, and nanotechnology) in his book Radical Evolution. Douglas Mulhall used the similar word “GRAIN” (genetics, robotics, artificial intelligence, and Nanotechnology). Ray Kurzweil, I think, used GNR (genetics, nanotechnology, and robotics) in his books.

But I prefer the acronym that’s being popularized by the ETC Group – “BANG.”

  • Bits,

  • Atoms,
  • Neurons, and
  • Genes.

It’s easy to remember and the word invokes the potential of these technologies to explode upon the world in ways that are both scary and exciting.

The 1934 Internet

A very smart fellow named Paul Otlet put the basic ideas together 74 years ago:

However, that was only his latest-and-greatest thinking on the subject. In fact, he attempted to implement a more primitive version of the Internet in the 19th century!

Testing the Many-Worlds Interpretation

Tipler says its doable:

The many worlds interpretation of quantum mechanics holds that before a measurement is made, identical copies of the observer exist in parallel universes and that all possible results of a measurement actually take place in these universes.

Until now there has been no way to distinguish between this and the Born interpretation. This holds that each outcome of a measurement has a specific probability and that, while an ensemble of measurements will match that distribution, there is no way to determine the outcome of specific measurement.

Now Frank Tipler, a physicist at Tulane University in New Orleans says he has hit upon a way in which these interpretations must produce different experimental results.

His idea is to measure how quickly individual photons hitting a screen build into a pattern. According to the many worlds interpretation, this pattern should build more quickly, says Tipler.

And he points out that an experiment to test this idea would be easy to perform. Simply send photons through a double slit, onto a screen and measure where each one hits. Once the experiment is over, a simple mathematical test of the data tells you how quickly the pattern formed.

The many worlds interpretation of quantum mechanics asserts that everything that could ever happen has happened and is happening and will happen across a vast — possibly infinite — number of parallel universes. If this idea were to be confirmed, it would arguably be the greatest scientific discovery of all time, even though it wouldn’t have any practical consequences. That is, we will continue to experience the world the same way whether we believe it’s the one and only world or we know that it is one of many.

Still, from a philosophical standpoint, it would be a pretty signfifcant development. It’s been suggested that we might one day prove the existence of parallel universes using qunatum computers or via elaborate experiments using the Large Hadron Collider. How interesting if it can be proved by simply performing measurements on an experiment that’s been around for years.
