A method does not deskill teachers, rather it empowers them

If it does not kill them , it makes them stronger : collisional evolution of star clusters with tidal shocks

The radii of young ( 100Myr) star clusters correlate only weakly with their masses. This shallow relation has been used to argue that impulsive tidal perturbations, or ‘shocks’, by passing giant molecular clouds (GMCs) preferentially disrupt low-mass clusters. We show that this mass–radius relation is in fact the result of the combined effect of two-body relaxation and repeated tidal shocks. Cl...

One Community Does Not Rule Them All

Online communities attract many users and have replaced search engines as the primary entry point to the Web. But, while some community platforms show a tremendous growth in terms of registered users, generated content and visitors, others at a certain point in time do not manage to acquire new users or even lose active or inactive members. A typical pattern that can be observed is a major play...

Chronic atrial fibrillation does not further decrease outward currents. It increases them.

Rapid atrial pacing causes electrical remodeling that leads to atrial fibrillation (AF). AF can further remodel atrial electrophysiology to maintain AF. Our previous studies showed that there was a marked difference in the duration of AF in dogs that have been atrial paced at 400 beats/min for 6 wk. We hypothesized that this difference is based on the changes in the degree of electrical remodel...

Cognitive Offloading Does Not Prevent but Rather Promotes Cognitive Development

We investigate the relation between the development of reactive and cognitive capabilities. In particular we investigate whether the development of reactive capabilities prevents or promotes the development of cognitive capabilities in a population of evolving robots that have to solve a time-delay navigation task in a double T-Maze environment. Analysis of the experiments reveals that the evol...
