Classifying variability of gene expression
Genetically identical cells or organisms grown in identical environments will differ phenotypically, because—even with a common script—gene expression is inherently variable, or noisy....

How to deal with too many dimensions and too few samples.
Noninvasive experimental techniques, such as magnetic resonance (MR), infrared, Raman and fluorescence spectroscopy, and more recently, mass spectroscopy (proteomics) and microarrays (genomics) have...

Researchers are not simply retrieving and repackaging what is already known, but are also deriving new knowledge by discovering connections that were previously unnoticed.
Not long ago, reading biomedical literature involved hours in the library combing through rows of dusty periodicals—not to mention pocketfuls of change for the copy machine. Now, although the...
