Fluids moving through pipes lose energy to friction along the walls. Collisions, defects, and random motion steadily break ...

Physicists at TU Wien have created an ultracold quantum gas where both energy and mass flow without any measurable loss, a result that defies the standard expectation that interacting quantum systems ...

Just as rivers move sediment across the land, turbidity currents are the dominant process carrying sediments and organic carbon from coastal areas into the deep sea. Turbidity currents can also ...

After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Turbidity currents in submarine canyons often involve large-scale movement of the seafloor. This discovery could help ocean engineers avoid damage to pipelines, communications cables, and other ...
