] To see what might happen if buckyballs got into the ] environment, Eva Oberdörster, an aquatic scientist at ] Southern Methodist University, put some into a fish tank ] at a concentration of 0.5 parts per million, along with ] nine largemouth bass. The buckyball-breathing fish ] experienced significant brain damage after 48 hours. ] Brain-cell membranes were disrupted, an affliction that ] has been linked to illnesses such as Alzheimer's disease ] in humans. ] ] Oberdörster's unpublished study, which was released last ] week, is one of the few completed studies looking at the ] potential risks of nanomaterials. There is some cause for ] concern. Two recent studies documented lung damage in ] animals after they inhaled a type of buckyball called a ] carbon nanotube. Another showed that nanoparticles can ] get into the brain if inhaled. ] ] They're also small enough to cross cell walls and leak ] into the nucleus, the home of an organism's DNA. And, in ] the case of titanium dioxide nanoparticles, they can kill ] bacteria. That's good news in a hospital, but bad news in ] the environment, where bacteria are extremely important ] for maintaining soil fertility, among other things.

] Check this shit out (Fig. 1). That's bonafide, 100%-real ] data, my friends. I took it myself over the course of two ] weeks. And this was not a leisurely two weeks, either; I ] busted my ass day and night in order to provide you with ] nothing but the best data possible. Now, let's look a bit ] more closely at this data, remembering that it is ] absolutely first-rate. Do you see the exponential ] dependence? I sure don't. I see a bunch of crap. ] ] Christ, this was such a waste of my time. ] ] Banking on my hopes that whoever grades this will ] just look at the pictures, I drew an exponential through ] my noise. I believe the apparent legitimacy is enhanced ] by the fact that I used a complicated computer program to ] make the fit. I understand this is the same process by ] which the top quark was discovered. Funniest. Lab Report. Ever. Kovar/Hall |

] Why should we want the universe to last forever, anyway? ] Lookâeither the universe has a purpose or it doesn't. ] If it doesn't, then it is absurd. If it does have a ] purpose, then there are two possibilities: Either this ] purpose is eventually achieved, or it is never achieved. ] If it is never achieved, then the universe is futile. But ] if it is eventually achieved, then any further existence ] of the universe is pointless. So, no matter how you slice ] it, an eternal universe is either a) absurd, b) futile, ] or c) eventually pointless. A really interesting article on Slate of all places on the end of the Universe. A lot of bizarre theories out there.... How Will the Universe End? - A cosmic detective story about the demise of the world, in three parts. By Jim Holt |

] CONSERVATIVE LYSENKOISM, CONTINUED. Tapped alum Chris ] Mooney reports here on a startling development: 20 Nobel ] Laureates have signed a statement calling on the Bush ] administration restore scientific integrity to the ] policymaking process. It's quite unprecedented, and very ] interesting. I've been following this topic -- often ] through Chris's valuable blog -- for the last two years, ] and I think this is emerging as one of the key political ] issues for 2004. For more reading, I'd check out the ] following three articles. First, Chris's profile of White ] House science advisor John Marburger in the Prospect. ] Second, this article by Nick Thompson documenting the ] growing divide between the GOP and the scientific ] community on a variety of issues where conservative ] theology conflicts with available evidence or scientific ] consensus. Finally, this piece by Richard Florida in the ] Washington Monthly, which explains how the Bush ] administration's anti-scientism (among other things) ] threatens our economic health. very interesting. goto http://www.ucsusa.org/global_environment/rsi/index.cfm to read about the scientist's movement to stop the distortion of science by the bush admin....
