Study reveals structures of six states of a rotary sodium ion pump

Six structures exhibited by the rotating sodium ion pump were reconstructed in 3D using cryo-electron microscopy. This analysis revealed that the rotor exhibits non-uniform rotation behavior due to partial structural interference ...

Perfection: The enemy of evolution

Scientists are often trained to seek out the absolute best solution to a given problem. On a chalk board, this might look something like drawing a graph to find a function's minimum or maximum point. When designing a turbojet ...

First electric nanomotor made from DNA material

A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles ...

Universal optothermal micro/nanoscale rotors

The fundamental rotation of micro and nano-objects is crucial for the functionality of micro and nanorobotics, as well as three-dimensional imaging and lab-on-a-chip systems. These optical rotation methods can function fuel-free ...

Boxing up molecular machines

Machines that are confined inside a cage or casing exhibit interesting properties by converting input energy into programmed functions. One such system is the mechanical gyroscope or gyrotop, a fascinating toy that amuses ...
