Could humans be capable of growing new limbs? Scientists are trying to figure that out with the aid of an unexpected resource: salamanders. Research shows that the amphibians' regeneration abilities ...

Tsukuba, Japan—Humans are among the most capable long-distance runners in the animal kingdom. However, body shape and composition vary individually, reflecting adaptations to common movement patterns.

Hierarchical communication between cells with distinct positional memories orchestrates the regeneration of missing limb structures in axolotls.

A passive prosthetic leg, says 23-year-old amputee Craig Hutto, is always a step behind. But a new leg built by researchers at Vanderbilt University "is only a split-second behind." Hutto, who is 6 ...

Sprinting is a motor task for humans using maximum physical features and demands considerable training. In this regard, an understanding of the leg morphology of sprinters from a biomechanical ...

People with spinal cord injuries often lose some or all their limb function. In most patients, the nerves in their limbs work ...

The nascent field of fluorescence-guided surgery (FGS) is fast growing, with potential to vastly improve the safety and efficacy of surgical procedures. In FGS, tissues of interest are targeted and ...

Human fingers and toes do not grow outward; instead, they form from within a larger foundational bud, as intervening cells recede to reveal the digits beneath. This is among many processes captured ...

Objective The objective of this study is to describe the mechanism of injury and situational patterns (based on ball possession and playing action leading to injury) of severe (lay-off time >28 days) ...
