Researchers create mathematical model of fruit fly eyes

Many researchers have tried to create a mathematical model of how cells pack together to form tissue, but most models have many different complicated factors, and no model is universal.

Researchers at Northwestern University have now created a functional equation — using only two parameters — to show how cells pack together to create the eyes of Drosophila, better known as the fruit fly. They hope that the pared-down equation can be applied to different kinds of tissues, leading to advances in regenerative medicine.

First complete computer model of human metabolism

Researchers at the University of California, San Diego, have constructed the first complete computer model of human metabolism. Available free on the Web, the model is a major step forward in the fledging field of systems biology, and it will help researchers uncover new drug pathways and understand the molecular basis of cancer and other diseases.
