Different microarray systems more alike than previously thought
A multicenter comparison of equipment that can analyze the expression of thousands of genes at once to create a genetic "fingerprint," suggests these different microarray technologies are more alike than once thought. Published in the May 2005 issue of Nature Methods, the study provides new hope that the mounds of information generated by these systems might actually be comparable, even t...All placebos not created alike
The debate about the existence of a placebo effect has heated up over the past year as more and more lab experiments are detecting immediate physiological responses to placebos. A new study takes placebo investigations out of the lab and into a clinical trial, showing a discernible placebo effect over time, according to an article in the Feb. 1 British Medical Journal. While researchers u...
