Light-controlled gearbox for nanomachines

Rewarded with a Nobel Prize in Chemistry in 2016, nanomachines provide mechanical work on the smallest of scales. Yet at such small dimensions, molecular motors can complete this work in only one direction. Researchers from ...

Mystery of the dark solitons

When your heart beats, blood courses through your arteries in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such ...

Destabilized solitons perform a disappearing act

When your heart beats, blood courses through your veins in waves of pressure. These pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. Scientists call such robust ...

Video: The universe in a cup of coffee

Reactions, the ACS YouTube channel that covers the chemistry of everyday life, is joining PBS Digital Studios, a network of original web series from PBS that explore science, arts, culture and more. To celebrate, the Reactions ...

Physicists observe diffusion of individual atoms in light bath

In a combination of experiments and theory the diffusion of individual atoms in periodic systems was understood for the first time. The interaction of individual atoms with light at ultralow temperatures close to the absolute ...

Formation of swarms in nanosystems

One of the striking features of self-organization in biomolecular systems is the capacity of assemblies of filamentous particles for synchronous motion. Physicists of Ludwig Maximilian University of Munich now provide new ...

High-precision control of nanoparticles for digital applications

For the first time ever, researchers have succeeded in creating arrangements of colloids – tiny particles suspended in a solution – and, importantly, they have managed to control their motion with high precision and speed. ...
