Magnetic Particle Snake
Magnetic particles suspended between two liquid layers in a magnetic field self assemble into snake like structures based on the movement of waves at the interface between the liquids.
A DNA transistor can precisely control the motion of a DNA molecule so that a sequencing device might be created in the future.
Nanoparticles Speed and Stick
A nanoparticle of 30,000 silicon atoms traveling at speeds in excess of 2,000 meters per second undergoes a phase change and sticks to a surface (video 2) that it would otherwise bounce off (video 1).
The microscopic vorticella, a single-celled organism shown here in slow motion, is one of the strongest biological engines in terms of specific power in the natural world.
A ceramic plate never "unshatters" even though it does not violate Newton’s laws of mechanics. Why not?
The electrical current running between two nanowires attracts an amoeba, which allows researchers to study the creature reducing the risk of damaging it.
Artificial cilia that mimic the tiny hairs that propel cells in water help study the chaotic fluid movements around the surface of a cell.
