Dynamite as a Railroad Builder

A dynamite intercellular highway

Any which way but loose back-to-back arrangement of kinetochores is not needed for correct alignment on the mitotic spindle, as shown by Hilary Dewar, Tomoyuki Tanaka (University of Dundee, UK), and colleagues. Sister chromatids are glued together by cohesin such that their kinetochores face opposing poles. This arrangement might thus prevent both chromatids from attaching to spindle microtubul...

Improvisational Builder: Improvisation as Conversation

To participate in musical improvisations, an interacting system must both generate appropriate musical materials and express those materials appropriately in collaboration with other performers. We have used results from the study of conversation and discourse to identify the major components for a theory of improvisation—listening, composing, and realizing. Our goal is a framework based on a m...

VILLIN2 Emerges as a Master Builder in Rice.

The architecture of a plant determines its ability to capture solar energy and thus has a striking effect on yield. Plant architecture is the product of coordinated patterns of cell division, expansion, and differentiation. Whereas the molecular mechanisms governing cell division are well established, those regulating cell expansion and differentiation are not. Studies indicate that the cytoske...

Dynamite: A Testbed for Multiple Mobile Robots1

We are experimenting with multiple mobile robots under visual control. The current goal of our work is to construct an architecture for robots engaged in cooperative and competitive behaviour. Multiple robots have recently been the focus of much attention; however, the little work that has been done with implemented systems has involved simple tasks and behaviours. We have initiated the Dynamo ...
