Keep quiet or be eliminated: How cell competition modulates morphogen gradients
Tissue patterning is an important process during embryo formation, as well in adult tissue, which ensures that groups of cells are correctly arranged to allow them to function properly. Many studies have attempted to understand how disruptive cells (arranged or signaling improperly) are removed from healthy tissues; none have provided a clear explanation, until now.

Vitamin D deficiency is associated with poor muscle function in adults aged 60+
New research from Trinity College Dublin shows that vitamin D deficiency is an important determinant of poor skeletal muscle function in adults aged 60 years and over. While resistance exercise is known to preserve muscle function, there is growing evidence that adequate vitamin D status may also be protective.
