10 Ways We Get the Odds Wrong
Silkweaver
by Silkweaver  6-20-2008    2
 And the two last ones: IX. We Love Sunlight But Fear Nuclear Power Why "natural" risks are easier to accept. X. We Should Fear Fear Itself Why worrying about risk is itself risky. Though the odds of dying in a terror attack like 9/11 or contracting Ebola are infinitesimal, the effects of chronic stress caused by constant fear are significant. Studies have found that the more people were exposed to media portrayals of the 2001 attacks, the more anxious and depressed they were. Chronically elevated stress harms our physiology, says Ropeik. "It interferes with the formation of bone, lowers immune response, increases the likelihood of clinical depression and diabetes, impairs our memory and our fertility, and contributes to long-term cardiovascular damage and high blood pressure."

 "...All the while scientists are monitoring their instruments and taking readings. After running a transect through the hurricane, the plane comes about and makes another penetration. A few more penetrations and the P-3 returns to home base, refuels, and prepares for another mission into the hurricane the next day, all in the name of science and trying to help make better forecasts and predictions for the people of the United States and Caribbean ..

  Maj. Gen. Taguba led the US Army's official investigation into the Abu Ghraib prisoner abuse scandal and testified before Congress on his findings in May 2004. Taguba retired in January 2007, later alleging that Pentagon officials had ordered him to retire for being "overzealous" in his criticisms of the military. He writes here, in the Preface to the report "Broken Laws, Broken Lives."

Genetically engineered cells make their own nanomagnets, providing clear MRI images.

by Silkweaver  6-20-2008    2
 If genetically engineering cells to produce their own magnetic nanoparticles proves successful, this provides a new window through which to view many biological processes as they unfold, from the formation of tumors to the migration of stem cells injected to treat disease. "It's just amazing that they can get a mammalian cell to actually make the material," says Lee Josephson, an associate professor at the Harvard Medical School's Center for Molecular Imaging Research. "I think it's a really meaningful piece of work."
