...early June with Chinese-made toothpaste. Following 100 deaths in Panama linked to cough syrup containing diethylene glycol (the ingredient had been mislabeled as glycerin, which is harmless), the FDA issued an import alert on all toothpaste made in China, tested the tubes it could find for the toxin and recalled the questionable batches. "Obviously it's not possible for us to test every product that is coming in to make sure it's meeting every standard we have," Acheson says. "It's got to be based on risk...
...this is to confuse the bacteria, hitting them with not just one natural toxin but two. At Vertex Pharmaceuticals in Cambridge, Mass., scientists are developing a new class of antibiotics that targets a pair of enzymes the microbes depend on to copy their genes and reproduce. Adapting in two directions at once slows down the bacteria enough to give the drug time to work. "Mathematically, it becomes much harder for the bacteria to develop resistance to different targets at the same time," says Dr. John Alam, the company's chief medical officer...
...watchers: an abrupt no. There were some obvious reasons for Russian intransigence. The case is a skein of disputed plots and subplots. Lugovoi and one companion - or two, according to some versions - met Litvinenko at a London hotel on Nov. 1. Litvinenko died 22 days later from the invisible toxin apparently swallowed at that meeting. British investigators have tried to unpick the events, linking Lugovoi to a trail of particles shed by the polonium. Lugovoi denies blame, while Russia says its constitution prevents it from handing over a citizen to a foreign power...
Alexander Litvinenko. Lugovoi is accused of poisoning Litvinenko, a former KGB operative who became a prominent dissident opposed to Russian President Vladimir Putin, with the radioactive metalloid polonium 210. The CPS's move, although welcomed by Litvinenko's widow, Marina, and officially backed by the British government, injected fresh toxin into Russian-U.K. relations already weakened by the affair. British Foreign Secretary Margaret Beckett told Russia's ambassador in London, Yuri Fedotov, that the U.K. expects "full cooperation." But Russia's own public prosecutor responded that the country's constitution does not permit it to extradite Russian citizens...
...researcher Serge Przedborski, drawing a parallel between crime-ridden areas and cellular environments. “What we found was that in fact, those normal motor neurons were dying due to the aspect of being surrounded by these mutant [support cells].” Though the identity of the toxin produced by these cells is still a mystery, the researchers are optimistic about the prospects of discovering it and finding drugs to combat it. “You’re looking at anywhere between three and four years,” Przedborski said. Lou Gehrig’s disease...
