http://www.sciencedaily.com/releases/2008/11/081117131709.htm

Construction of new coal-fired power plants in the United States is in danger of coming to a standstill, partly due to the high cost of the requirement — whether existing or anticipated — to capture all emissions of carbon dioxide, an important greenhouse gas. But an MIT analysis suggests an intermediate step that could get construction moving again, allowing the nation to fend off growing electricity shortages using our most-abundant, least-expensive fuel while also reducing emissions.

Among those trials published, unexplained discrepancies between the FDA submissions and their corresponding publications—the addition or deletion of outcomes, changes in the statistical significance of reported outcomes, and changes in overall trial conclusions—tended to lead to more favorable presentations of the drugs in the medical literature available to health care professionals.

'Gen X' author tells how guys really view age

http://www.msnbc.msn.com/id/25847518/print/1/displaymode/1098/

"A few days ago, I had a business lunch with a guy I thought was about 10 years older than I am. I'm 46, and he looked to be 55 and resembled every English teacher you've ever had. At the end of lunch he said, "You know, I was born the same week as you..." and went on to discuss all the same music we listened to in high school. Meanwhile, it was all I could do to compose myself while looking around for a reflective surface — a knife blade, the hologram on my Visa card — to convince myself I didn't look 55 like this guy did. I felt as if I had progeria, that disease in which you age half a century in five years. That's what growing older does to a guy."

Some Cancers Found By Mammograms Would Have Naturally Regressed, Study Suggests

http://www.sciencedaily.com/releases/2008/11/081124165117.htm

Breast cancer rates increased significantly in four Norwegian counties after women there began undergoing mammography every two years, according to a new report.

Rates among regularly screened women remained higher than rates among women of the same age who were screened only once after six years, suggesting that some of the cancers detected by mammography may have spontaneously regressed had they not been discovered and treated.
