Comment Re:The tools used to build StoneHenge (Score 2) 615

I have seen a wax cylinder shaved and recorded over in a demonstration in a class, although I can not recall if it was music or science. The cylinder was a replica made by a hobbyist, and I recall that a phonograph horn was made from paper and a straight pin to demonstrate how simply the technology is. However, this would qualify as far as the NPR article is concerned. Although I may be old enough that this isn't done in schools anymore so only qualifies as anecdotal evidence rather than proof.

With asbestos and lead, the tools still exist but were simply redesigned with other materials. In the case of the shoe-fitting x-rays, we do not have a replacement tool with anywhere near the same function. The closest we have is this contraption, and it would take a very strong argument to convince me that those are the same tool.

NB: correct contextual usage of the word "contraption" obviously gives greater weight and style to my argument. Nanny Nanny.

While I personally agree with you, that line of reasoning will not convince believing friends and family that the house isn't haunted.

That's okay, though. Because a thorough scientific investigation will not convince believers either. The slightest wobble in any of your readings will be read as a haunting. Lack of wobble in the readings will be read as a haunting. A complete failure to find any evidence of ghosts will be taken as evidence that the ghosts do not want to be found.

And then there's a good chance that your work and or words will be taken out of context in a way that seems to support ghosts, but will be worded in such a way that a FORMER SKEPTIC now BELIEVES!

Basically, don't do it.

I wouldn't be surprised to have my suspicion proven wrong... it's just my gut feeling that there are several different issues. I think we're getting closer to the point where we are altering natural systems to the point that a tiny nudge that would otherwise have no measurable impact on a healthy population ends up toppling some parts over the edge. We're getting better at identifying "safe and effective" levels in the lab, but those levels are only "safe and effective" in a controlled laboratory environment. Just like DDT was likely "proven" safe and effective, except we neglected the purely environmental reality of bioaccumulation.

The supposed fact (I haven't seen any published studies, so it's all hearsay and anecdotes so far) that organic bee farms don't experience CCD is quite important, except it doesn't tell which one of us is right. But it does suggest a course of action we would probably both agree on.

Technically, they weren't finding piles of dead bees. The initial presentation was often that the bees were simply missing.

But yeah, pedanticism aside, your main point still stands. Colony Collapse Disorder (CCD) is a pretty serious problem facing beekeeping and any agriculture that relies heavily on bees for fertilization, such as almonds. There are many many possibilities on what causes CCD. I personally have a feeling that it's going to end up being something like cancer where there isn't one type of CCD, but there are many different disorders with a similarly presenting outcome. I wouldn't be surprised if many of the collapses are multivariate, such as bee colony transport and exposure to crop pesticides reducing the bees immune system, which leads to infestation of mites, which is treated with more pesticides further stressing the bees to the point where they get a viral infection which then opens the door for secondary fungal or bacterial infections which actually kill the bees. It is thought that the hives are often found empty because if a bee "realizes" that it's sick, it will try to get away from the hive to prevent spread, but the widespread immune system impairment causes a full blown epidemic out of what would have been a couple of sick bees. Basically any of the individual stresses wouldn't be enough for the entire colony to collapse, but added up the bees don't stand a chance. Large problems like this never seem to have one magic pill that just fixes everything.

One of the assumptions is safe: low oxygen environment. This bacterium does not "eat" metallic iron, but reduces dissolved iron oxide which requires a reducing (I.E. anaerobic) environment. How the existing iron structure turns into iron oxide is another question. My brief poking around on the internet (I'm not going to call it research) seems to indicate that these bacteria live in conjunction with many other bacteria and fungi in an associated called a rusticle which only seems to form on wrought iron. Modern steel should not be affected by this particular association, and chances are anything exposed to open seawater probably would be naturally exposed to all of the component organisms needed. Weaponizing this phenomenon would probably end up being more like developing some sort of fertilizing agent that hastens the colonization and growth rate of the appropriate colonies of organisms and would likely either be so bulky as to be noticed during routine maintenance, or require multiple reapplications which would increase the likelihood of being discovered. I really don't foresee this being more effective than traditional sabotage methods.

Researching this phenomenon is probably far more likely to give us a more thorough understanding of oxidation and improvements in the rust resistance of steel.

Who knows... the whole thing seems to be speculation at this point. After a bit of digging I think I found the paper that is being referenced here. It looks like they isolated some organism and figured out its taxonomy using molecular techniques and very little research on the bacteria's actual metabolism. For all I know this particular bacteria could be simply feeding on those that are doing the actual oxidation and reduction. It looks like I'd be able to learn a bit more on the topic of bacterial mediated corrosion from this document. Maybe I'll have that digested by the time this article comes up as a dupe.

Due to your fervent believe in choice, you would deprive others of the choice to use a walled garden "just works" device? Your ire is especially misguided considering that the CR48 (The only chrome device users have gotten their hands on yet... anything else would be mere speculation) can be set into developer mode with literally the push of a button.
