Using computational models, researchers are gaining traction toward understanding what makes a stem cell a stem cell; how gene expression drives stem cell differentiation; why studying stem cell heterogeneity is important; and, ultimately, how stem cells control their fate.
To the casual observer, stem cells offer the almost magical promise of—Voila!—turning into exactly the kind of cell needed to repair an injured spinal cord or replace a damaged organ. And...

From hardened software to scientific productivity, the NCBCs have changed the landscape for biomedical computing. What will happen when their funding expires?
It has been eight years since the National Institutes of Health (NIH) funded the first National Centers for Biomedical Computing (NCBCs). With two or three years remaining in the program (...

An opportunity and a challenge
When discussing biocomputation startups, there’s one thing people agree on: These days, they don’t generate much excitement among venture capitalists.
“In the 1990s, there...

AgentCell is the first simulation program to model a biochemical network at the molecular, single cell, and population levels simultaneously.
When a bacterium swims toward food, it follows a chaotic path, alternating between spinning randomly and driving forward, or ‘tumbling’ and ‘running.’ Computer scientists at...

How to share knowledge, data, tools, and computational resources in a sustainable manner
Once upon a time, a deep divide existed between scientists who did and those who did not have easy access to scientific content (journals, lectures, data), hardware (imaging devices, lab instruments...

Exploring the current state of connectomics--in the midst of hype
Connectomics is having a moment. Following on the heels of genomics, proteomics, transcriptomics, metabolomics, and microbiomics, the latest “omic” to seize the spotlight is generating...

Postdocs get a glance at the entire field and their first inside view of NIH grant-making
If he were a graduate student now, Francis Collins would be studying computational biology. That’s what the Director of the National Institutes of Health (NIH) told a rapt audience at the...

Describing information flow within cells
Like corporate and governmental organizations, cells rely on middle managers to keep things running smoothly. These “middle managers” function as a critical bridge that controls the flow...

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...
