Molecules

Researchers thought that what enabled complex fluids to break apart was their elasticity. But a crack in a nonelastic simple fluid has them questioning that idea.

The mechanical process of cell division exerts powerful, if microscopic, forces. How do the molecular machines that power it manage the strain?

Scientists keep detecting new forms of ice. According to simulations, there could be many more left to find.

A newly proposed explanation for the slipperiness of ice has revived a centuries-long debate.

Earth’s radiation can send some molecules spinning or vibrating, which is what makes them greenhouse gases. This infographic explains how relatively few heat-trapping molecules can have a planetary effect.
