...phenomenon began in 1998 when two Silicon Valley entrepreneurs circulated an online petition demanding that Congress, in their phrase, "move on"--that is, stop trying to impeach President Clinton. Thus was born MoveOn.org which now has 3.2 million members. Most of the bloggers who have become Netroots leaders can trace their influence back only a couple of years, to 2003 and '04, when the growth of partisan liberal online activism was spurred by a strain of antiwar, anti-Bush fervor and frustration with congressional Democrats for not standing up to the President. Blogs like Daily Kos and MyDD grew rapidly...
...spinach-related E. coli poisoning. Until Wednesday, investigators at the CDC and the Food and Drug Administration (FDA) had only suspected that fresh, bagged spinach had caused nearly 150 people to fall ill, and led to one death, from the bacterial infection. Researchers had not been able to trace the bacteria to fresh spinach until they tested one of several opened bags of the leafy vegetable from the homes of sickened people. DNA fingerprinting confirmed not only the presence of E. coli, but also linked the bacteria found on the spinach to the same ones isolated from patients. This...
...than text-based communications because live conversations, when converted to digital bits for transmission on the Internet, are harder than e-mail to search for offensive words. Voice information is generally discarded once a call is over, while e-mail is stored indefinitely on servers, making it easier to trace the authors. Services like Skype also use encryption technology to scramble calls, so eavesdroppers can't decipher what's being said without a software "key" to decode the transmission. There's another benefit, too: in Vietnam's crowded Internet caf?s, it's tough for police to discern which...
...authorities are fighting back, using such tactics as surveillance, infiltration and the cutting of suspected dissidents' Internet connections. Government officials won't comment on enforcement matters. But administration sources tell TIME that because they can't easily trace VoIP with technology, agents have joined and surreptitiously monitored VoIP chat rooms. Participants in antigovernment discussions use aliases, but agents try to lure them into revealing their true identities...
...except that Phipp, 30, was in a dark room at a South London medical center, lying inside a loudly whirring functional magnetic resonance imaging (fMRI) scanner that mapped her brain as video images flickered before her eyes. Brain scanners, which use radio waves and a powerful magnetic field to trace oxygenated blood to areas of neural activity, are used mainly to study or diagnose brain diseases. But Phipp's brain was being scrutinized by researchers to see how it reacted to the TV pictures--specifically, whether she responded to ads differently at night than in the morning...
