I couldn’t quite figure out how to categorize this one. There are stories of children being raised by wolves, but here’s the first case, at least of which I’m aware, of a man being raised by chickens.

It will be certain to be the butt of jokes, but of course it’s a tragic situation. I really mean it–once you get past the absurdity of it, it really was catastrophic for the poor guy.

But it could have been worse–he was fortunate that it happened after he had at least developed the ability to speak. Children raised without human contact from birth never develop the ability to do so–there’s a certain critical point in development and the wiring of the brain during which speech is acquired, and if you miss it, you’ve apparently missed it forever. The story claims that he is learning (or relearning) how to speak, and presumably to eat with utensils instead of pecking.

Of course, as the old joke in the Woody Allen movie (Annie Hall?) went, they may not want to go too far in rehabilitating him. They won’t get any more eggs. Besides, he may have a thrilling career ahead of him as a sports team mascot.

So anyway, it turns out that Wood’s Hole, being one of the nations finer scientific establishments, actually has internet access. Who’d a thunk it? A technological widget developed for the transmission of porn, spam, and offers from deposed Nigerian dictators, being used by scientists as a means of remote collaboration. Just goes to show the innovative and unexpected uses to which researchers can turn everyday objects.

Obviously I’m being a little ironic above. More seriously, my wife just showed me a really cool little trick that allows a >$10,000 piece of scientific equipment to be replaced by common items costing under $100. It’s a neat little illustration of nonlinear thinking and creative problem solving on the part of a graduate student who simply did not have enough money to buy the high end gear, so she tried to figure out a way to do it on the cheap. Nobody told her it wouldn’t work, and she was really keen on getting the work done, so she kept trying until she made it work. It’s a very cool little application, so why am I being evasive about details? Well, it involves a basic technique for genetic engineering. If this was September 10th 2001, I’d blissfully blog away. In the current environment I think dropping the cost of making genetically modified organisms by over $10,000 is not necessarily in the best interest of anyone. I had a nice little post all lined up to talk about technology and creativity and the importance of persistence, but I think I’ll just leave well enough alone.

It’s only a matter of time before genetic engineering techniques come within reach of basically anyone with a couple million dollars. The long pole in the tent right now is just the sheer amount of time it takes to carry out all the work, and the scattershot nature of the results. Given time, and especially given volunteers willing to die, a terrorist attack using GMOs is a real possibility. Technology is advancing rapidly, and established technologies are becoming cheaper and more accessible. The only effective way of reducing the risk of a mass casualty attack is to undermine the ideas behind the ideologies that drive the attackers. There will always be people who want to cause destruction, but the fewer collaborators they have the lower their chances of success.

The reason I’ve been a little quiet these past few days is that I’ve been preparing a talk for presentation at the IEEE International Conference on Plasma Science, held in Baltimore this year. I presented yesterday, and it was generally well received. The topic was technical and boring, so I won’t gn into details here. The talk that ended the session I was at was particularly interesting, though, so I thought I’d blog about it.

The talk in question was presented by J. E. Brandenburg of the Florida Space Institute, titled Microwave Enhancement of Inertial Electrostatic Confinement of Plasma for Fusion: Theory and Experiment. Inertial Electrostatic Confinement (IEC) uses two (or more) nested spherical grids charged to a high relative voltage to accelerate ions towards the common center of the grids, where they collide and fuse. Philo Farnsworth patented an IEC concept he called the Fusor, and there are all the usual conspiracy theories about suppression of his research surrounding the history of the Fusor, though I suspect the truth of the matter has a lot to do with the fact that it didn’t really work very well, at least for power generation.

I’m a member of a group of young fusion researchers who are trying to figure out how to make fusion happen in our lifetimes. This is nontrivial because ‘young’ in this case means under 40, and current plans from DOE don’t put fusion power on the grid for another 35+ years. Given the accuracy of government forecasts a whole year down the line, I’m not holding my breath.

I think that the single largest factor holding up the development of commercial fusion is not physics, its program structure. We need to revolutionize the way fusion research is structured, and the best way to do that is to bring the power of the market to bear. Prizes have been suggested (notably by Bob Bussard). I offer here an alternative proposal, seeking your feedback.

The goal is to encourage private funding. This means finding a way to reduce the risk to investors in potential fusion schemes. If a given idea can pass a basic peer reviewed sanity check (doesn’t violate any laws of physics), DOE should offer to insulate investors from some measure of risk. As a concrete proposal, say DOE will purchase all the intellectual property assets of any innovative energy company which closes down after raising private venture funding. There would be some limit, indexed to the amount of money raised, say 1/2 the total venture funds raised, up to a limit of $50 million expended by DOE per company. The physical plant would remain property of the investors or creditors. DOE would pay an external auditor to catalog and organize the intellectual property assets, and would make them freely available to interested parties.

There would have to be sensible mechanisms for peer review and for deciding when to shut down (presumably the investors would make that call), but I don’t see showstoppers there. I think the idea would work, but getting congress to agree is likely to be hard. There’s a real danger of the money disappearing after a venture is funded, thanks to diversion to some more worthy cause, like rainforests in Iowa.

Anyway please comment, kvetch, suggest, advise, discuss, either in comments here or in email to me.

Ian Murray (who seems to be having spam problems) should find this one fascinating. There’s a brief, but interesting article in this week’s Economist about the disturbing prevalance of shaky statistics in peer-reviewed scientific papers.

I firmly believe that the single most important area of scientific research is cognitive psychology (the rigorous branch of psych, not the motherlovin’ it’s-just-a-cigar-to-me-but-you’re-a-pervert freudian crap). There’s an interesting article on the results of a cross cultural comparison of behavior in some simple games here. This sort of thing helps get at what human nature really is and what’s just cultural overlay. The results are interesting, and generate more questions than answers, but at least the questions are well posed.

btw, welcome back, Rand. I hope the moving problems resolve painlessly.

I came across a rather nice little page on aerodynamics for nonspecialists today. I’ve been slowly teaching myself the basics needed to understand the design of aircraft, and this page provided some good simple background. Plenty of pictures, and clear text.

This was the last day of scientific presentations, and it ended on a high note with a banquet, about which more later. L. J. Perkins did an excellent overview of fusion physics, and mentioned a couple of things in passing that caught my attention. The most significant is that p-B11 is viable as a fuel in fast ignition ICF. In ICF a fuel pellet is compressed by depositing energy symmetrically on a spherical capsule, blowing off the outer layer. The resulting reaction force collapses the pellet to fusion relevant densities, heating in the process. Fast ignition is a scheme where you hit the compressed pellet at or just before the moment of maximum compression with an additional energy source (ion beam or laser) focused on a small spot. Ignition of the fusion fuel is initiated at the spot, and this serves as a spark plug which sends a shock front through the high density fuel, triggering fusion throughout the volume. The nice thing about ICF is that the fuel density is really high, so the mean free path for photons is really short, smaller than the size of the pellet. This means that bremstrahlung, the traditional enemy of p-B11, is less of a problem, since bremstrahlung photons are captured within the pellet, rather than escaping as they do with the lower density plasmas used in magnetic confinement.
