Cosmic Strings
Why are stars and galaxies clumped rather than spread out evenly in space? What drew them together? Thin strings of energy created during the birth of the universe may have provided the attraction...
Collective Computation in Neuronlike Circuits
Electronic circuits based on neurobiological models are able to solve complex problems rapidly. Their computational properties emerge {rom the collective interaction of many parts linked together in a network...
Courtship in Unisexual Lizards: A Model for Brain Evolution
An all-female species of whiptail lizards presents a unique opportunity to test hypotheses regarding the nature and the evolution of sexual behavior
The Fracturing of Glass
Only recently have the atomic interactions underlying glass fracture been defined. The work suggests ways to slow or even stop the growth of cracks in glass and other brittle materials
