New Pill May Help Divers Fend Off the Bends

Thursday, March 25th, 2004

I find the focus of the article (and its headline) peculiar, given the actual research finding. From New Pill May Help Divers Fend Off the Bends:

Divers may soon be able to take a pill that fends off decompression sickness when surfacing, according to a team of Norwegian scientists.

‘The bends’ happen when sudden pressure changes lead to bubbles of gas forming in the bloodstream.

Researchers found that a bout of intense exercise around 20 hours before a dive dramatically reduced bubble formation, New Scientist magazine reported Wednesday.

One theory suggests exercise stimulates the release of nitric oxide (NO), which dilates blood vessels and makes them more slippery and difficult for tiny bubbles to stick to.

The Norwegian team thinks it may be possible within a decade to develop an NO-releasing drug for divers which would mimic the effect of exercise.

Is a bout of exercise the day before a dive that inconvenient?

Phileas Frogg: Again the eternal conflict between the Real and the Nominal, and once more the Nominal lies. Never forget, lying is an act of aggression, and should always be treated as such. The more egregious the lie, the more aggressive the act. Respond accordingly.

Phileas Frogg: History is a gift and its study a blessing; even the people whose effects I have come to despise are so obviously superior to our present milieu that one can’t help but feel a sort of scruffy abashedness in the presence of their biographies. And, of course, it gets worse the further back you go. One wonders at the impression a fully fledged Adam in the Garden, before the Fall, would have had on us scampering apes.

Phileas Frogg: “Interestingly, working-class Americans are more likely to read local news, while the wealthy and highly educated favor national and global news.” I wonder how much of this is social norms vs self-perception. Do the wealthy and educated feel in touch with (or that they should be in touch with) national and global events, or is it mere mimicry? How about the working-class? The two are necessarily mutually exclusive of course, but I wonder if there’s a different primary...
Phileas Frogg: As advances in weapon’s have improved the range and effectiveness of the individual soldier’s impact on the battlefield, the number of soldiers has increased in importance relative to the quality of any individual soldier. It’s the Thermopylae Principle in reverse because of weapons advancements. Reminds me of RTS balancing, where to effectively implement melee units developers need to give them either unrealistic speed or durability relative to the ranged capabilities of...
Bob Sykes: Calling Mohamed Farrah Aidid’s militia a mob is a bit much, but they were lightly armed and poorly trained. However, they defeated the US/UN mission to Somalia, or at least fought it to a draw. We’re still fighting Aidid’s grandchildren, and we still haven’t won. The war is now in its 4th decade, with no end in sight. Settling aside our Indian Wars (1607 to 1918). Somalia is the longest US war.
McChuck: Anybody who has ever played a wargame can tell you that your defenses can handle a certain amount of opposition, but when enemy numbers, regardless of quality, exceed that number, you get overrun. The mobs in Mogadishu back in 1993 weren’t well organized, weren’t well equipped, weren’t well trained, and weren’t well led. But there sure were a whole lot of them shooting at the Rangers.

Phileas Frogg: The class divide in the US is as deep and wide as any as has existed in history, but instead of acknowledging the divide, much less trying to bridge it, we have chosen moralization and mutual animosity, which will be the death of us.

Phileas Frogg: In conjunction with the Rob Henderson excerpt one can safely conclude that neither drug use, nor sexual immorality, can be meaningfully correlated with class. “But poverty causes crime!” Does it?
Bruce: Green energy is a patronage fraud, and Terraform Industries is working with it. But their tech isn’t a fraud.
Handle: What is Henderson taking about? I was under the impression that it was a broadly believed meme and one frequently portrayed in popular entertainment for several generations before Henderson was born that college kids got drunk and enjoyed / experimented with recreational drugs quite a lot. Maybe Rob’s poorer friends couldn’t afford to watch those episodes of South Park or didn’t hear about George W Bush’s “youthful indiscretions”? Man, the left really is...
Bob Sykes: How effing stupid are we supposed to be. The energy input to make the methane will be several times the energy of combustion when the methane is burned. And, of course, all the methane will become exactly the amount of carbon dioxide originally removed from the atmosphere. Net, no carbon dioxide removal. And considering all the carbon produced during the manufacture of the Terraform system and the solar/wind systems, this proposal actually increases atmospheric CO2. And the cost claims are...
