Our bodies are always moving, even when we don’t realize it. We churn through a solar system on a wobbly planet, stand upon ...

Siegfried Musser, PhD, and his team in the Department of Cell Biology and Genetics at the Texas A&M College of Medicine have ...

Heating a substance makes its atoms and molecules move faster. This happens whether the substance is a solid, a liquid, or a gas. It’s not easy to see it happen in a solid but let’s try it for a ...

It occurs down a concentration gradient - molecules move from an area of high to lower concentration. This does not require a supply of energy because diffusion is a spontaneous process.

Scientists at Yokohama National University, in collaboration with RIKEN and other institutions in Japan and Korea, have made an important discovery about how electrons move and behave in molecules.

Membrane transport proteins are specific and selective for the molecules they move, and they often use energy to catalyze passage. Also, these proteins transport some nutrients against the ...

Why did the colors move in cool ways? To answer this question, we have to use chemistry. Think about the atoms and molecules that the milk and detergent are made of and why they would act in this ...

Other signaling molecules must move much farther to reach their targets. One example is follicle-stimulating hormone, which travels from the mammalian brain to the ovary, where it triggers egg ...
