Elephants sing low the same way humans do

(Phys.org) -- Mammals produce sounds in two ways, either via the flow of air over vocal folds (vocal chords), as in humans and many other mammals, or via active muscular contractions as in the cat’s purr. Until now no ...

Spectrin proteins spring into action to restore nucleus

When you lift weights, carry heavy boxes, or engage in physical activity, the cells in your body stretch and deform to accommodate your movements. But how do your cells recover, or return to their original state, once you ...

Identifying molecular guardian of cell's RNA

When most genes are transcribed, the nascent RNAs they produce are not quite ready to be translated into proteins - they have to be processed first. One of those processes is called splicing, a mechanism by which non-coding ...

New views of intracellular channel that controls skeletal muscle

Using high-resolution electron microscopy, Columbia University Medical Center (CUMC) researchers have uncovered new details of the structure and function of an intracellular channel that controls the contraction of skeletal ...

Scientists discover secreted protein helps repair and grow muscles

Scientists from Tokyo Metropolitan University have discovered that a protein called platelet-derived growth factor subunit B (PDGF-B) is continuously secreted from skeletal muscle cells and helps to repair muscles by encouraging ...
