London taxi drivers exploit neighbourhood boundaries for hierarchical route planning.

Humans show an impressive ability to plan over complex situations and environments. A classic approach to explaining such planning has been tree-search algorithms which search through alternative state sequences for the most efficient path through states. However, this approach fails when the number of states is large due to the time to compute all possible sequences.

A test of the social withdrawal syndrome hypothesis of bulimia nervosa.

Background: The study examined the social withdrawal syndrome (SWS) hypothesis of bulimia nervosa (BN). According to the hypothesis, eating disorders such as BN are associated with a coherent set of social withdrawal cognitions, affect, and behavior.

Participants And Procedure: Eight-eight young female adults completed a standardized measure of bulimic symptoms and measures of social withdrawal (affective withdrawal, trust beliefs in close others, and disclosure).

Future directions in human mobility science.

We provide a brief review of human mobility science and present three key areas where we expect to see substantial advancements. We start from the mind and discuss the need to better understand how spatial cognition shapes mobility patterns. We then move to societies and argue the importance of better understanding new forms of transportation.

The Impact of Spatial Orientation Changes on Driving Behavior in Healthy Aging.

Objectives: Global cognitive changes in older age affect driving behavior and road safety, but how spatial orientation differences affect driving behaviors is unknown on a population level, despite clear implications for driving policy and evaluation during aging. The present study aimed to establish how spatial navigation changes affect driving behavior and road safety within a large cohort of older adults.

Methods: Eight hundred and four participants (mean age: 71.

Lack of racial and ethnic diversity in lung cancer cell lines contributes to lung cancer health disparities.

Lung cancer is the leading cause of cancer death in the United States and worldwide, and a major source of cancer health disparities. Lung cancer cell lines provide key models for molecular studies of lung cancer development and progression, and for pre-clinical drug testing. To ensure health equity, it is imperative that cell lines representing different lung cancer histological types, carrying different cancer driver genes, and representing different genders, races, and ethnicities should be available.
