To understand biology—and provide appropriate medical care—scientists need to understand interactions across multiple scales. Hence the Physiome.
This is the reality of human biology: events span a 109 range in lengthscale (molecular to organismal) and a 1014 range in timescale (molecular movement to years). To understand this biology—...

Computation shows that the skull guides the wrinkling
In the four months before birth, a fetus’s brain grows from a smooth tube of neurons into a highly crinkled, convolved mass of tissue. Because the cerebral cortex has a surface area nearly...

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...

There is growing recognition that epigenetics may be just as important as genetics in human health and disease.
In the early 19th century, Jean-Baptiste Lamarck explained evolution as the inheritance of acquired traits; he believed that changes due to behaviors and exposures in one generation could be passed...

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...

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...
