It’s hard to keep a straight face, and especially difficult if you meet someone who looks angry or happy. This the conclusion drawn from experiments carried out by Ulf Dimberg, professor of psychology at Uppsala University, Sweden, and his associates. The results, which are presented in the journal Cognition and Emotion, show that we are not in full control of our facial muscles: their reactions are controlled by unconscious mechanisms.
It is well known that emotions find direct expression in our body language, gestures, and facial appearances, and these expressions of feeling are anchored in special, biologically given, so-called “affective programs.” One question facing researchers is to what extent these reactions are conscious and can be controlled or whether they are tied to unconscious mechanisms.
In his research Ulf Dimberg has studied the association of facial expressions to emotional reactions and has published acclaimed results showing that even if pictures of, say, angry or happy faces are exposed so quickly that they cannot be consciously perceived, people being tested react in the form of rapid responses in their own facial muscles that mirror the expressions they have been unconsciously exposed to.

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...
