Many systems models are strikingly vulnerable to even small changes in the variables
Systems biologists seek to model many complex biological interactions all at once. Typically, they input tens or even hundreds of variables to produce predic- tions about a system—for example,...

Pattern-classifiers interpret fMRI data
Peek inside the skull of a couch potato watching reruns on TV and you’ll see non-stop patterns of blood flow throughout the brain. If you learn to pick out which activity patterns match up with...

Mechanical forces drive many processes in the human body, from organ and tissue formation during development, to stem cell differentiation, to wound healing. Until recently, scientists could only...

Synthetic biologists explain cell behaviors while desinging new ones
Without synchronized clocks—whether embedded in our body’s cells or programmed into our desktop computers—any kind of coordinated activity is impossible. So after synthetic...

Simulations can teach us how young bodies and faces develop; how an artery compensates for decades of fatty plaque deposits by growing and thickening its walls; how tissue engineers can best coax endothelial cells to develop into organized sheets of skin for burn patients; and how cancerous tumors invade neighboring tissue.
For better or for worse, and on many levels, our tissues never stop growing and changing. While developing from childhood to old age, we grow not only bone, cartilage, fat, muscle and skin, but also...

Balancing Breadth and Depth
The last decade saw a proliferation of training programs at the intersection of life science and computation, with more than 60 new degree and certificate programs launched in the United States alone...

Predicting protein localization
Joe works in a factory; Jane works in a hospital; protein X works in the Golgi apparatus. Just as one might guess a worker’s job by knowing where he or she is employed, biologists can guess a...

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...

Simulating how cells form patterns.
Normal zebrafish have stripes, but mutant forms may display spots, blotches, or labyrinthine patterns. It’s a scenario that Rudyard Kipling might turn into a wonderful “just-so”...

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...
