Attentional Distractions Do Not Influence Lumbar Spine Local Dynamic Stability during Repetitive Flexion-Extension Movements.

The association between low back pain and lumbar spine local dynamic stability (LDS) appears to be modulated by if and how someone catastrophizes about pain, suggesting that the cognitive perceptions of pain may influence an individual's ability to control lumbar spine motion. Previous work also demonstrates that directing cognitive resources and attentional focus can influence movement performance. Therefore, we aimed to examine whether distracting attentional focus would influence lumbar spine LDS during repetitive flexion-extension movements.

Plastic pollution on the world's coral reefs.

Coral reefs are losing the capacity to sustain their biological functions. In addition to other well-known stressors, such as climatic change and overfishing, plastic pollution is an emerging threat to coral reefs, spreading throughout reef food webs, and increasing disease transmission and structural damage to reef organisms. Although recognized as a global concern, the distribution and quantity of plastics trapped in the world's coral reefs remains uncertain.

Ageing of juvenile coral grouper () reveals year-round spawning and recruitment: implications for seasonal closures.

Temporal patterns in spawning and juvenile recruitment can have major effects on population size and the demographic structure of coral reef fishes. For harvested species, these patterns are crucial in determining stock size and optimizing management strategies such as seasonal closures. For the commercially important coral grouper ( spp.

Student Perceptions of Superimposed Mixed Reality Anatomy: A Bridge Between the Virtual and Physical.

A prototype mixed reality model was developed in which three-dimensional holograms of musculoskeletal anatomy were superimposed over a physical skeleton model, conferring tactile sensation to the bony attachments of virtually observed muscles. Fifty-three second-year medical students piloted this innovative format and provided feedback on its effectiveness as a learning modality.
