In what could be a breakthrough in cancer therapy, researchers report in The New England Journal of Medicine today that they succeeded in bolstering a patient's immune system enough to wipe out late-stage malignant tumors on its own.

Jeremy Nicholson's Gut Instincts: Researching Intestinal Bacteria [Scientific American Magazine]
Lundi 16 Juin 2008 - 22:00 - 6 mois, 3 semaines depuis - 8 lectures - Presse spécialisée - Scientific American
Editor's Note: The extended Q&A with Jeremy Nicholson mentioned in the July magazine can be found here. Jeremy Nicholson was only trying to be thorough. It was 1981, and the young biochemist was using a technique called nuclear magnetic resonance spectroscopy, which can identify chemicals based on the magnetic properties of atomic nuclei. In particular, Nicholson wanted to study how red blood cells absorb cadmium, a metal that causes cancer. Realizing that he would achieve the best results if he could mimic the cells’ natural environment, he added a few drops of blood to the cells and ran the test. [More]

Ghost Lusters: If You Want to See a Specter Bad Enough, Will You?
Lundi 27 Octobre 2008 - 07:00 - 2 mois, 1 semaine depuis - 8 lectures - Presse spécialisée - Scientific American
Most scientists dismiss the vast majority of ghost sightings as hoaxes. But researchers in Canada, England and elsewhere are exploring what happens in the brain to create the illusion that something is "haunted." So far, they have found evidence that some apparitions may be brain benders caused by spiking EMFs (electromagnetic fields), and possibly even extremely low-–frequency sound waves (known as infrasound) so subtle that the ear does not register them as noise.EMFs emitted by power lines and towers, clock radios and other electrical sources may help debunk myths that people or things are haunted, says Michael Persinger, a neuroscientist at Laurentian University in Sudbury, Ontario, Canada, who has conducted research on the topic. One such study, published in 2001 in Perceptual And Motor Skills chronicles the experiences of a teenager who in 1996 claimed to be receiving nocturnal visits--one sexual--from the Holy Spirit. The 17-year-old girl, who had sustained mild brain damage at birth, said she also felt the presence of an invisible baby perched on her left shoulder. [More]
