A mathematical model for animal stripes
The back of a tiger could have been a blank canvas. Instead, nature painted the big cat with parallel stripes, evenly spaced and perpendicular to its' spine. Scientists don't know exactly how stripes develop, but mathematicians since the 1950s have been modeling possible scenarios.

Physics attempts to explain why stem cells move
Research has shed light on the complex interactions of stem cells and molecular diffusion in brain tissue. The calculations may explain phenomena such as stem cell differentiation and even the formation of the cortex of our brain.

Epigenetic change leads to cerebellum circuitry
Before birth and throughout childhood connections form and continue to form between neurons in the brain. To date, scientists have a pretty good understanding of how these circuits functionally get set up. But, they don't know how much is the result of our DNA template — and how much is epigenetic.

Id tags define developing neural circuits
The human brain is composed of circuits made up of neurons, cells specialized to transmit information via electrochemical signals. Like the circuits in a computer, these neuronal circuits must connect in very unique ways in order to function. But with billions in a single human brain, how does a neuron make the right connection with the right cell?

Mechanism for how organs branch found
The lung is as much a natural work of art as a functioning organ with its twisting bronchial branches and delicate curls. Now Princeton researchers have observed this artistry unfold. While growing mouse embryo lungs, they arrived at a surprising conclusion about forces to help shape lungs.
