A ferry protein in the pancreas safeguards beta-cells from high-fat diet induced stress

Every time we eat, the glucose level in our body goes up. This spurs our pancreatic machinery into action and through intricate physiological mechanisms, appropriate amounts of insulin are produced, our blood glucose levels are controlled, and we remain healthy.

Newly identified mechanism regulates the distensibility of the heart

A healthy heart beats 50 to 100 times a minute and pumps 8,000 litres of blood around our body every day. A precondition for this function is the elasticity of the cardiac walls, which dilate as blood flows in (diastole) and contract again as the blood flows out (systole).
