Convective mixing of fluids goes faster when the container is tilted—a finding that may impact the choosing of geological sites for carbon dioxide storage.

Paper pyramids hovering in an oscillating air column enlighten us about the stability of flying insects.

Salt crystallizing on walls or old artifacts forms in discrete bunches, rather than coating the surface, because of an unexpected feedback effect, according to experiments and simulations.

The paddling motion works not just for swimmers but also for fliers, as new high-speed video observations of fruit flies show.

Even though global warming remains a heated political topic, physicists should not ignore the intellectual challenge of trying to model climate change.

As aqueous emulsions containing colloidal particles dry, two very different behaviors are observed.

Experiments now quantitatively confirm the standard model of electrokinetics, in which electric fields drive the flow of electrolytes, potentially leading to better sensors and biomedical diagnostic devices.

The rotational flow of fluid in a heated tank containing some heavy beads periodically reverses direction, mimicking some aspects of the motion of Earth’s continents over geologic time.
