A ring of beads connected to tentacles A modeling study shows how chemical reactions can stimulate motion in simple systems, like the structure here—made of enzyme coated beads connected to ...

Traditionally, chemical reactions have been described as one-line “equations” in which substrates, say A and B, convert purposefully but rigidly into a desired product, say C. Naturally, it has been ...

Researchers have observed steric effects—the interactions of molecules depending on their spatial orientation (not just between their electrons involved in bonding)—in a chemical reaction involving ...
