Smoking may increase risk for lung disease (March 11, 2011) -- Researchers have found that approximately one out of every 12 adult smokers have abnormal lung densities present on chest computed tomography images suggestive of interstitial lung disease which is associated with substantial reductions in lung volumes. In addition, despite being positively associated with smoking, these lung densities were inversely not associated with emphysema. ... > full story
Americans have higher rates of most chronic diseases than same-age counterparts in England (March 11, 2011) -- Despite the high level of spending on health care in the United States compared to England, Americans experience higher rates of chronic disease and markers of disease than their English counterparts at all ages.

New view of human nerve cells opens door to potential drug targets (March 11, 2011) -- Scientists have found a way to uncover potential drug targets that have so far remained hidden from researchers’ view. By applying the new method to a type of nerve cell critical to regulating body temperature, the authors found more than 400 “receptors” (structures that bind other molecules, triggering some effect on the cell) responding to neurotransmitters, hormones, and other chemical signals. This represents 20 to 30 times more receptors than previous studies had identified. ... > full story
Trauma patients have higher rate of death for several years following injury (March 11, 2011) -- In a study that included more than 120,000 adults who were treated for trauma, 16 percent of these patients died within 3 years of their injury, compared to an expected population mortality rate of about 6 percent, according to a new study. The researchers also found that trauma patients who were discharged to a skilled nursing facility had a significantly increased risk of death compared with patients discharged home without assistance. ... > full story

Japan today is struggling with the aftermath of a massive 8.9 earthquake on a subduction zone, a short distance offshore, which unleashed a devastating tsunami that killed hundreds and has turned large parts of cities into rubble. The disaster is also a "wake up call" for the Pacific Northwest, a noted geologist says. ... > full story
