A multi-year evaluation of medical student performance on and perceptions of collaborative gross anatomy laboratory examinations.

Collaborative testing and its benefits have been reported in diverse disciplines across different types of academic institutions. However, there has been minimal research conducted on collaborative assessments in medical schools, particularly in the gross anatomy laboratory. The objectives of this study were to explore the effect of collaborative anatomy laboratory examinations on student performance and to gauge student perceptions of this assessment format.

Changes in wingstroke kinematics associated with a change in swimming speed in a pteropod mollusk, Clione limacina.

In pteropod mollusks, the gastropod foot has evolved into two broad, wing-like structures that are rhythmically waved through the water for propulsion. The flexibility of the wings lends a tremendous range of motion, an advantage that could be exploited when changing locomotory speed. Here, we investigated the kinematic changes that take place during an increase in swimming speed in the pteropod mollusk Clione limacina.
