Roberta F. White of Boston University led the study of sarin nerve gas, which used new scanning technology. Though the results are preliminary, the study is notable for being financed by the federal government and for being the first to make use of a detailed analysis of sarin exposure performed by the Pentagon, based on wind patterns and plume size.Link. And here's the site for NeuroToxicology (pay access only, and the site navigation is abominable)The report, to be published in the June issue of the journal NeuroToxicology, found apparent changes in the brainâs connective tissue â its so-called white matter â in soldiers exposed to the gas. The extent of the brain changes â less white matter and slightly larger brain cavities â corresponded to the extent of exposure, the study found.
Previous studies had suggested that exposure affected the brain in some neural regions, but the evidence was not convincing to many scientists. The new report is likely to revive the long-debated question of why so many troops returned from that war with unexplained physical problems.
Reader comment: Patrick Snajder says,
You noted in the link to the NeuroToxicology that the site navigation, from publisher Elsevier, is abominable. You are probably aware, but Elsevier is currently being boycotted by some scientists for its involvement in arms trade shows: Link, and current news here.] The fact that Elsevier was involved was, ironically or not, rooted out by another Elsevier journal, The Lancet: Link.

I'm absolutely delighted to receive this tremendous honour from the world's oldest learned society. There are very few countries (including my own) where a somewhat cheeky book about happiness could win a science prize -- but the British invented intellectual humour and have always understood that enlightenment and entertainment are natural friends. So God bless the empire!
Eli Lilly, the company behind Prozac, originally saw an entirely different future for its new drug. It was first tested as a treatment for high blood pressure, which worked in some animals but not in humans. Plan B was as an anti-obesity agent, but this didn't hold up either. When tested on psychotic patients and those hospitalised with depression, LY110141 - by now named Fluoxetine - had no obvious benefit, with a number of patients getting worse. Finally, Eli Lilly tested it on mild depressives. Five recruits tried it; all five cheered up. By 1999, it was providing Eli Lilly with more than 25 per cent of its $10bn revenue...


I've seen Salvador DalĂ's famous Alka Seltzer commercial many times, but this video shows two I didn't know about: DalĂ pitching Lanvin chocolates and Veterano brandy. There are others on the YouTube page too!
Five screws were drilled into Malloy's neck. Four more were drilled into her head to keep it stabilized. Then a thing called a halo -- rods and a circular metal bar -- was attached for added support...
If you've ever spent any time on your sofa wishing that you could take it wherever you wanted to go, you might want to talk to Marek Turowsk.

Rep. Tim Ryan (D-Ohio) and Rep. Jim McGovern (D-Mass.) are among a handful of congresscritters participating in an experiment in which they must subsist on standard US food stamp rations for one week.
Folks like me who rely on Internet streaming to listen to great public radio stations like KEXP in Seattle or KCRW in Los Angeles - may be disheartened by the recent ruling by the Copyright Royalty Board (CRB) requiring public broadcasters to pay the same (outrageous) royalties as commercial broadcasters, and charging them back-pay.
I cranked up the voltage of the electric shocks to my tongue. It didn't feel bad, actually â like licking the leads on a really weak 9-volt battery. Arnoldussen handed me a long white foam cylinder and spun my chair toward a large black rectangle painted on the wall. "Move the foam against the black to see how it feels," she said.

"Of the 200 million stars in the Milky Way galaxy, someâperhaps manyâmay have inhabited planets and spacefaring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours. We hope someday, having solved the problems we face, to join a community of galactic civilizations. This record represents our hope and our determination and our goodwill in a vast and awesome universe."
