Are our thoughts made of electricity? Not the familiar kind of electrical signals that travel up and down wires in our computer or nerves in our brain, but the distributed kind of electromagnetic field that permeates space and carries the broadcast signal to the TV or radio.
Professor Johnjoe McFadden from the School of Biomedical and Life Sciences at the University of Surrey believes our conscious mind could be an electromagnetic field. “The theory solves many previously intractable problems of consciousness and could have profound implications for our concepts of mind, free will, spirituality, the design of artificial intelligence, and even life and death,” he said.
Most people consider ‘mind’ to be all the conscious things that we are aware of. But much, if not most, mental activity goes on without awareness. Actions like walking, changing gear in your car or peddling a bicycle can become as automatic as breathing. The biggest puzzle in neuroscience is how the brain activity that we’re aware of (consciousness) differs from the brain activity driving all of those unconscious actions.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
