Abstract: Cardiac trabeculae are widely used as experimental muscle preparations for studying heart muscle. However, their geometry (diameter, length, and shape) can vary not only among samples, but ...

Loss-of-function in epicardial proteins called Numb Family Proteins leads to left ventricular noncompaction, or spongy heart, presenting with pediatric-onset heart failure. The loss of function is ...

Spicules are small, needle-like or star-shaped structures made of calcium carbonate or silica, serving as skeletal elements in various marine invertebrates, particularly sponges. These structures ...

Centuries after Leonardo watched a heart beat, a fresh answer is taking shape. A new wave of imaging, genetics, and computation shows that the fine mesh of muscle lining the heart—called ...

The heartbeat is synonymous with life. It’s one of the of the first essential functions to begin during development and to end at death. “The heart is one of the first organs to form and function ...
