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 ...

NASA delays Mars copter flight for tech check

NASA has delayed by at least several days the first flight of its mini-helicopter on Mars after a possible tech issue emerged while testing its rotors, the US space agency said Saturday.

NASA space copter ready for first Mars flight

The helicopter that NASA has placed on Mars could make its first flight over the Red Planet within two days after a successful initial test of its rotors, the US space agency said Friday.

The smallest motor in the world

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor ...

Intelligently recovering and recycling balsa wood

There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, ...
