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...

Bringing models closer to reality
When the ill-fated space shuttle Columbia launched on January 16, 2003, a large piece of foam fell off and hit the left wing. Alerted of the impact, NASA engineers used a computer model to predict...

How errors in data, software, and methodology can teach us how to do better
In 2006, a paper in Nature Medicine suggested a novel and potentially revolutionary method for predicting patient responses to cancer therapies using gene signatures. The finding piqued the interest...

They've gone from hype to backlash. Now it's time for reality: How microarrays are being used to benefit healthcare
When DNA microarray technology emerged more than a decade ago, it was met with unbridled enthusiasm. By allowing scientists to look at the expression of enormous numbers of genes in the genome...

Set objectives and follow through
Having engineered several scientific software applications for public consumption, the authors know from experience that the process offers unique challenges. Typically, the algorithms being...

Modelers should take the lead.
Many collaborators 1 with whom modelers2 work have little or no training in modeling3 and so it is natural that they may be cautious,...

Public databases impact not only how research is done but what kind of research is done in the first place.
The setting: a scientific conference in January 2008. The speaker, Bruce Ponder, MD, PhD, an oncology professor at Cambridge University, is describing a previously unknown link between a particular...

How some tools are already impacting patients
Medical decision-making is often more art than science, requiring physicians to exercise judgment in the face of complex factual circumstances. But now a few tools offer the opportunity to...
