'Water wires' may play bigger role in cellular function

Each of our cells is surrounded by a complex membrane that functions as a biological border, letting ions and nutrients such as salt, potassium and sugar in and out. The guards are membrane proteins, which do the hard work ...

Scientists develop inexpensive method to produce E-sail tethers

Thin metallic tethers for Coulomb drag devices that tow satellites and spacecraft can now be produced more easily than before. Scientists of the Finnish Meteorological Institute have developed a method to produce multi-wire ...

Solitonics in molecular wires could benefit electronics

Soliton descriptions for the conducting polymers polyacetylene—descriptions based around a type of solitary wave—caused great excitement when they first broke in the seminal reports by Su, Schrieffer, Heeger (SSH) and ...

An all-electric magnetic logic gate

A team of researchers from ETH Zurich and the Paul Scherrer Institute has developed a way to build an all-electric magnetic logic gate. In their paper published in the journal Nature, the group describes their device and ...

Researchers make world's fastest molecular shuttle

Thanks to a clever chemical design, researchers at the University of Amsterdam's Van 't Hoff Institute for Molecular Sciences (HIMS) have succeeded in making a very fast molecular machine. The moving parts shift more than ...

The nano-guitar string that plays itself

Scientists at Lancaster University and the University of Oxford have created a nano-electronic circuit which vibrates without any external force.

2-D topological physics from shaking a 1-D wire

Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong ...
