Blogging--It's Good for You [Scientific American Magazine]
Jeudi 22 Mai 2008 - 06:25 - 6 mois depuis - 20 lectures - Presse spécialisée - Scientific American
Self-medication may be the reason the blogosphere has taken off. Scientists (and writers) have long known about the therapeutic benefits of writing about personal experiences, thoughts and feelings. But besides serving as a stress-coping mechanism, expressive writing produces many physiological benefits. Research shows that it improves memory and sleep, boosts immune cell activity and reduces viral load in AIDS patients, and even speeds healing after surgery. A study in the February issue of the Oncologist reports that cancer patients who engaged in expressive writing just before treatment felt markedly better, mentally and physically, as compared with patients who did not.Scientists now hope to explore the neurological underpinnings at play, especially considering the explosion of blogs. According to Alice Flaherty, a neuroscientist at Harvard University and Massachusetts General Hospital, the placebo theory of suffering is one window through which to view blogging. As social creatures, humans have a range of pain-related behaviors, such as complaining, which acts as a “placebo for getting satisfied,” Flaherty says.

Scientific American Magazine: Regaining Lost Luster
Dimanche 16 Décembre 2007 - 16:01 - 11 mois, 1 semaine depuis - 20 lectures - Cancer - Scientific American
The past 15 years have been a roller coaster for gene therapy. After being touted in the early 1990s as “the medicine of the future,” gene therapy left an 18-year-old dead and three others with leukemia; in July it was tied to the death of a 36-year-old Illinois woman undergoing treatment for rheumatoid arthritis, although further investigation cleared her therapy of the blame. Gene therapy scientists, however, believe they can put the bad news behind them, thanks to a handful of recent developments and others just over the horizon.
