    We will research, improve, innovate and ultimately implement nanotech solutions for one simple reason: we can. It's been the same right throughout human history.

    The views of the objectors, no matter how well founded and how well intentioned, will not lead to r&d into nanotech (or any other new technology, including human cloning) being stopped. At best it might be delayed, but even then the money to be made by Big Business makes this unlikely IMO.

    Can anybody think of any kind of new technology that has been abandoned, or even significantly delayed, through alleged (or real) risks ? I suspect new technologies are only abandoned because they are not feasible either technically or commercially (cost too much, too late to market etc) rather than for some ethical or environment consideration.

Like when he claimed that abestos insulation would have prevented the fall of the WTC towers. And when somebody points out the flaws in his claims (abestos is not that superior to other kinds of insulation), he just insists that he never said what you think he said. That makes any link to his site a non-argument. And plenty of reputable scientists do consider DDT a health hazard. Hey, by the time it was banned, it was reaching toxic levels in human milk.

          God, I can't wait for that crazy motherfucker to go away.

          Most of what he says there is reasonably accurate, but he also does a good job of leaving out most of the actual problems DDT has. He does a nicely comprehensive job documenting the predictably hysterical behavior of pop-scientists and the inefficacy of committees in doing anything useful, but jumping from there to advocating unbanning DDT is kinda insane.

          DDT is poison. This is the whole point. It's also fat-soluable. One of the many things that Junky doesn't talk about is DDT's effect of bats. Bats were hit pretty damn hard by DDT, because bats migrate, and when bats migrate, they first load up on fat, which is full of DDT, so when they start burning their fat in migration season, the DDT level in their blood suddenly goes through the roof and they all die and end up all over your back yard.

          Same thing happens to people. Like most fat-soluable chemicals, DDT is cumulative. In an environment saturated with DDT, like the US in 1970, you take in more than you pass. The .0026mg/kg body weight Junky mentions as a safe dose just means that it takes about 5 years of eating fish, vegetables, etc. for you to build up enough DDT in your fat to give you the effects of a good stroke. The trick to avoiding that is to never lose weight.

          Based on just the numbers Junky has, you take a 250lb farmer who's been ingesting 17, 18mg/day of DDT on the farm, have him work hard for 25 years, have a heart attack when he hits 50, decide to try and come down to 180, succeed, and then suddenly he drops dead because he's been flooding his system with backed-up DDT at 400mg/day as he burns off the fat.

          Regardless, the millions of lives are being saved anyway. We push DDT all over the 3rd world, it's not like Ghana's banned the stuff. The sad thing is we give them the same old shit that mosquitos have been selected to avoid and tolerate since facism was still cool instead of the vastly more effective, safer, and more stable products we've come up with in the intervening 1-1/4 centuries.
        • Indiscriminately spraying tons of DDT over every domestic crop in the world is a Bad Idea - DDT is a pretty nasty substance to have in the food chain in massive quantities; I'm sure I don't need to review the effects. But, if it were used correctly, the way its inventor intended, it would be the Magic Bullet against malaria, without wreaking massive environmental havoc.

      Yes, there is a huge backlash against GM crops in Europe and Africa (and other places too). It's NOT, however, due to the technology itself, but rather it's a backlash against the companies concerned making the modded seeds sterile, thus forcing farmers into subsistence and reliance on a single source of seeds forever (the ultimate genetic customer lock-in), or worse yet, having those seeds spread to normal crops, rendering THEM sterile. That's why countries refused shipments of American excess grain unless they were milled down - they didn't want their citizens planting the sterile seeds and condemning themselves to a barren wasteland when those seeds don't germinate.

    Among other things they address the 'grey goo' or uncontrolled replicator issue.

    One of the things that I appreciated about this article was how it only spent a small bit on the grey goo hypothesis. The folks who propose any kind of a goo should step back from the science fiction, and read some biochemestry and microbial ecology. Energy is probably the primary limited resource for replication and there just is not that much out there available to nano-scale machines or organisms.

    The medical concerns should be taken seriously however. The Center for Biological and Environmental Nanotechnology has a nice page [rice.edu] that promises to be a clearinghouse for information on these issues.

    Some of the best evidence for the feasibility of advanced nanotech is that the government has recently started up a disinformation campaign as a smokescreen to accelerate their own research. They did the same thing back in the 40's when developing nuclear weapons: publicly poopooing it on the one hand to discourage others, while actively developing it on the other.

    A salient quote from a nanodot.org article [nanodot.org] on this subject:

    After the seminar, I happen to bump into Drexler and have a rare opportunity to speak with him alone. I bring up the possibility that there could be a secret military project to develop nanoassemblers, and the current government position in the nanotech debate is a disinformation program.

    Following the briefest of pauses, Drexler looks me in the eye and replies in the same high, clear voice I'd heard him use during the panel discussion, "Those things are hard to know about." He still has his game face on.

    All of us on /. like to cheerlead the coming wave of nanotech, but it's looking more all the time that while we may be on the cusp of a new industrial revolution, like the first IR, it will bring horrors to match its benefits. Probably the most significant point made by the article is that while this tech could be very beneficial, due to our lack of understanding of surface chemistry of most living organisms, some of the byproducts could be toxic to levels previously unknown to exist.

    Significant is this bit from the article:

    On average the reactions [to nanotube inhalation] were worse than those in mice given equal amounts of quartz particles, which toxicologists use as their "serious damage" standard.

    And this is from one dose, and they further state that even without continued exposure, the existing particles continued to produce damage, presumably beyond what a single exposure to quartz dust might produce.

    I fear that we'll rush headlong into this without thorough research, and do significant damage to ourselves and the rest of the world. Yah, that sounds all "tree huggy," but when they talk about accidentally killing all soil microorganisms over a large area, frankly, that kind of scares me.

    I'm starting to tilt towards a rant, so I'll keep this short, but given our recent history (asbestos, PCBs, tetraethyl lead), we're probably going to find ourselves chasing waste streams yet again, only much worse this time around.

    After having read the article, Yep I RTFA.

    Good article overall. Points out that the extent of nanotechnology is likely to be less than some hope and fear.

    The gray goo ideal is hampered by design, energy and speed/movement constraints which means that it's only going to be a problem if we haven't the technology to combat isolated outbreaks.

    We can't put the genie back in the bottle, someone is going to study this technology and use it for unfriendly ends. The only question is will we have the knowledge and skills necessary to counter that.

    I believe that restrictive regulation would make it more likely that we wouldn't have the resources to fight such threats. I also believe that there is a limited period of vulnerability until all citizens have defenses as part of their normal biotechnological compliment. The less restriction on research in the bio/nano technology arena the faster I believe we can get through this threatening period.

    As an aside on "Prey", I've noticed over the years that Mr. Crichton has made it a point to use his status and writing talents against Bio and Nano technologies. I understand that he has every right to do so, but I also believe I've a right to point out such.
