Synaptogenic Proteins and Synaptic Organizers: “Many Hands Make Light Work”

Synaptogenesis is thought to be mediated by cell adhesion proteins, which induce the initial contact between an axon and its target cell and subsequently recruit and organize the presynaptic and postsynaptic protein machinery required for synaptic transmission. A new study by Linhoff and colleagues in this issue of Neuron identifies adhesion proteins of the LRRTM family as novel synaptic organi...

Many Hands Make Light Work: Further Studies in Group Evolution

When niching or speciation is required to perform a task that has several different component parts, standard genetic algorithms (GAs) struggle. They tend to evaluate and select all individuals on the same part of the task, which leads to genetic convergence within the population. The goal of evolutionary niching methods is to enforce diversity in the population so that this genetic convergence...

Many Robots Make Short Work

1. Holding a meeting At the SRI Artificial Intelligence Lab, we have a long history of building autonomous robots, from the original Shakey (remember the STRIPS planner?) through Flakey [Congdon 1993] and more recently, the Pioneer class of small robots. Our current research focuses on realtime vision for robots, and multirobot planning using an agent-oriented architecture. For the AAAI contest...

Many hands make overlooked work: Over-claiming of responsibility increases with group size.

Logically, group members cannot be responsible for more than 100% of the group's output, yet claims of responsibility routinely sum to more than 100%. This "over-claiming" occurs partly because of egocentrism: People focus on their own contributions, as focal members of the group, more than on others' contributions. Therefore, we predicted that over-claiming would increase with group size becau...
