Swimmers' wake structures are not reliable indicators of swimming performance.

The structure of swimmers' wakes is often assumed to be an indicator of swimming performance, that is, how momentum is produced and energy is consumed. Here, we discuss three cases where this assumption fails. In general, great care should be taken in deriving any conclusions about swimming performance from the wake flow pattern.

A simple three-dimensional microfluidic platform for studying chemotaxis and cell sorting.

Lab Chip

Microbial chemotaxis plays a key role in a diversity of biological and ecological processes. Although microfluidics-based assays have been applied to investigate bacterial chemotaxis, retrieving chemotactic cells off-chip based on their dynamic chemotactic responses remains limited. Here, we present a simple three-dimensional microfluidic platform capable of programmable delivery of solutions, maintaining static, stable gradients for over 20 hours, followed by active sorting and retrieval of bacteria based on their chemotactic phenotypes.

Introduction: Substance use disorders, particularly alcohol use disorders, represent a significant public health problem, with adolescents particularly vulnerable to their adverse effects. This study examined the possible anxiolytic and antidepressant effects of biotin, a crucial vitamin for brain function, in attenuating the behavioral and neurobiological changes associated with alcohol withdrawal in adolescent rats.

Materials And Methods: Sixty male Sprague-Dawley rats were exposed to a 20% ethanol solution for 21 days, followed by a 21-day drug-free period to assess long-term behavioral and physiological changes.

Spatially ordered recruitment of fast muscles in accordance with movement strengths in larval zebrafish.

In vertebrates, skeletal muscle comprises fast and slow fibers. Slow and fast muscle cells in fish are spatially segregated; slow muscle cells are located only in a superficial region, and comprise a small fraction of the total muscle cell mass. Slow muscles support low-speed, low-force movements, while fast muscles are responsible for high-speed, high-force movements.
