Molecular dynamics is a tool for simulating the interactions between atoms or molecules. It utilizes basic Newtonian physics, by treating bonds and angles as springs, to approximate the motions of molecular structures. Because it is computational, it allows researchers to test hypotheses with unprecedented resolution...

Nevus, or as it is often called in common language, mole, is a benign neoplasm that can affect any of the cell types that populate the skin surface or epidermis. Examples of types of nevi include epidermal nevi and connective tissue nevi. In addition there...

Of course, the notion of biological evolution...

Biochemistry is that branch of chemistry that applies to chemical reactions in cells of organisms as big as a cow and as small as a bacterium. These biochemical reactions that take place inside the cells are amazingly organized and accurate. This organization and accuracy stem...
