Scientific experimentation is based on examining falsifiable hypotheses, and not simply using relatively meaningless experiments to prop up thedogma du jour.

Psychiatrists can draw upon long clinical experience with adult patients to surmise why antidepressant medications foster suicidal thoughts and behavior in some children, as the US Food and Drug Administration warned this fall.
Low-calorie diets extend lifespan in almost every model tested, but scientists can't yet agree on what controls this phenomenon.
The ion channel field has been a bit charged up lately, thanks largely to an impressive series of crystalline structures published by Rod MacKinnon's group at Rockefeller University.
As formal and methodological as it sometimes appears, science remains at its heart a process of storytelling.

These papers were selected from multiple disciplines from the Faculty of 1000, a Web-based literature awareness tool http://www.facultyof1000.com.T.A. Allen et al., "The SINE-encoded mouse B2 RNA represses mRNA transcription in response to heat shock," Nat Struct Mol Biol, 11:816–21, September 2004.A small, noncoding RNA, called B2, is expressed during heat shock and represses transcription from RNA polymerase II. Interestingly, B2 RNA is transcribed from a DNA region previously thought to
When scientists make long-term research plans, they must try to anticipate how emerging technologies will influence their work in the coming years.
Scientists from Manhattan to Pasadena, Moscow to Johannesburg, responded to The Scientist's question, "What gift do you most want this holiday season, and why?" Answers included the practical (sliceable gel blocks), the whimsical (a Star Trek tricorder), and meteorological (another El Niño). But what they all had in common was the desire for that most intangible and elusive of gifts: hastened progress in the researchers' respective fields.TREKKIAN DELIGHTFor upcoming missions to Mars and Eu
