A study published in the October issue of the American Journal of Psychiatry by an Italian group of investigators headed by Professor Giovanni A. Fava (University of Bologna) suggests, that with appropriate psychosocial interventions, half of the patients with recurrent depression could be still well and drug free six years after termination of treatment, instead of being linked to long term drug treatment.
A number of controlled trials have suggested that cognitive behavior strategies may decrease the risk of relapse in major depressive disorders. The risk of relapse in depression is strongly related to the number of depressive episodes and to the amount of residual symptoms. There is a paucity of studies use nonpharmacological strategies for preventing recurrence in depression. In one of this study, cognitive behavior treatment of residual symptoms was found to yield a significantly lower relapse rate than clinical management in recurrent depression at a 2-year follow-up.
The objective of this investigation was to provide a 6-year follow-up of cognitive behavior treatment versus clinical management. Forty patients with recurrent major depression who had been successfully treated with antidepressant drugs were randomly assigned to either cognitive behavior treatment of residual symptoms (supplemented by lifestyle modification and well-being therapy) or clinical management. In both groups, antidepressant drugs were tapered and discontinued. A 6-year follow-up was undertaken. During this period, no antidepressant drugs were used unless a relapse ensued. Cognitive behavior treatment resulted in a significantly lower relapse rate (40%) at a 6-year follow-up than did clinical management (90%). When multiple recurrences were considered, the group that received cognitive behavior treatment had a significantly lower number of relapses in comparison with the clinical management group. Cognitive behavior treatment was found to be effective in decreasing the residual symptoms of depression. By deferring the psychotherapeutic intervention until after pharmacotherapy, psychotherapy could concentrate only on the symptoms that did not abate after pharmacotherapy. The fact that most of the residual symptoms of depression are also prodromal and that prodromal symptoms of relapse tend to mirror those of the initial episode provides explanation for the protective effect of this targeted treatment. Cognitive behavior treatment may act on those residual symptoms of major depression that progress to become prodromal symptoms of relapse.

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...
