To fully understand and treat respiratory diseases, it is important to determine the flow pattern of air and particulates through the alveoli. In Biomicrofluidics,, scientists from the Harbin Institute of Technology in China created a model alveolar system that mimics the breathing action of the human lung and allows visualization of flow patterns within the alveoli.

Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases.

The investigators designed a chip that includes tubes arranged like the structure of a bifurcation point in the bronchial network.

There's the old saying in dieting that one must "breakfast like a king, lunch like a prince, and dine like a pauper," based on the belief that consuming the bulk of daily calories in the morning optimizes weight loss by burning calories more efficiently and quickly. But according to a new study published in Cell Metabolism, whether a person eats their largest meal early or late in the day does not affect the way their body metabolizes calories. However, people who ate their largest meal in the morning did report feeling less hungry later in the day, which could foster easier weight loss in the real world.
