NASA helicopter's mission ends after three years on Mars

NASA's Ingenuity Mars helicopter, which made history by achieving the first powered flight on another world, has officially ended its nearly three-year mission after sustaining rotor damage during its last outing, the space ...

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 ...
