New method found for moving tiny artificial swimmers

Princeton researchers have debuted a novel way of generating and potentially controlling locomotion in tiny objects called artificial swimmers. These swimmers have sparked considerable interest for their potential applications ...

Swimmers warned about oil after Georgia ship spill

Health officials warned swimmers and fishers to be on the lookout for oil sheens off two Georgia islands after oil spilled from an overturned cargo ship while crews were dismantling it.

Tiny swimming donuts deliver the goods

Bacteria and other swimming microorganisms evolved to thrive in challenging environments, and researchers struggle to mimic their unique abilities for biomedical technologies, but fabrication challenges created a manufacturing ...

Liquid crystal droplets as versatile microswimmers

Nature's most common swimmers are single-celled organisms such as microalgae that swim toward light sources, and sperm cells that swim toward an ovum. For a physicist, cells are simply biochemical machines, which must obey ...

Actively swimming gold nanoparticles

Bacteria can actively move towards a nutrient source—a phenomenon known as chemotaxis—and they can move collectively in a process known as swarming. Chinese scientists have redesigned collective chemotaxis by creating ...

Can microswimmers swim through gel?

Researchers from Tokyo Metropolitan University have studied how microswimmers, like bacteria or sperm, swim through fluids with both solid and liquid-like properties, e.g., gels. They found that subtle changes in a swimmer's ...
