How a New Hope in Cancer Fell Apart - NYTimes.com "The episode is a stark illustration of serious problems in a field in which the medical community has placed great hope: using patterns from large groups of genes or other molecules to improve the detection and treatment of cancer. Companies have been formed and products have been introduced that claim to use genetics in this way, but assertions have turned out to be unfounded. While researchers agree there is great promise in this science, it has yet to yield many reliable methods for diagnosing cancer or identifying the best treatment. Instead, as patients and their doctors try to make critical decisions about serious illnesses, they may be getting worthless information that is based on bad science."  (nytimes.com)

Medicare cuts may fall hard on Boston teaching hospitals - The Boston Globe "Massachusetts teaching hospitals would lose $322 million, or about two-thirds of the federal dollars they receive for the training of medical residents, under a bipartisan proposal to tamp down the rising costs of Medicare and reduce the federal deficit.
