A new interdisciplinary Stanford University initiative called NeuroCircuit aims to find the specific brain circuits that are responsible for mental-health conditions and then develop ways of noninvasively stimulate those circuits to potentially lead to improved treatments for depression, anxiety, and post-traumatic stress disorder. "You see things activated in brain images but you can't tell just

As we age, we have an increasingly harder time ignoring distractions. But by learning to discriminate a sound amidst progressively more disruptive distractions, we can diminish our distractibility, new research in Cell Press journal Neuron reveals. A similar strategy might also help children with attention deficits or individuals with other mental challenges. Distractibility (the inability to

(Forschungszentrum Juelich) Scientists in Jülich have, with the help of computer simulations, discovered a combination of materials that strengthens the so-called Friedel oscillations and bundles them, as if with a lens, in different directions. With a range of 50 nanometers, these 'giant anisotropic charge density oscillations' are many times greater than normal and open up new possibilities in the field of nanoelectronics to exchange or filter ...

(Forschungszentrum Juelich) Van der Waals forces act like a sort of quantum glue on all types of matter. Scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. They demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast. Their findings could help to improve simulation methods... More

(Vienna University of Technology) Particles or waves traveling through disordered media are scattered at small impurities. Surprisingly, the density of these impurities does not affect the overall dwell time the particle -- or wave -- spends inside the medium. This remarkable finding applies not only to particles and waves, but also to crawling ants or drunken sailors hitting streetlamps.

(Institute of Physical Chemistry of the Polish Academy of Sciences) For several years, it has been known that superfluid helium housed in reservoirs located next to each other acts collectively, even when the channels connecting the reservoirs are too narrow and too long to allow for substantial flow. A new theoretical model reveals that the phenomenon of mysterious communication 'at a distance' between fluid reservoirs is much more common than pr... More

Put rats in an IMAX-like surround virtual world limited to vision only, and the neurons in their hippocampi* seem to fire completely randomly — and more than half of those neurons shut down — as if the neurons had no idea where the rat was, UCLA neurophysicists found in a recent experiment. Put another group

Imagine an electronic implant that delivers a drug when triggered by a remote wireless signal — then harmlessly dissolves (no post-surgical infection concerns, no fuss, no muss) within minutes or weeks. That's what researchers at Tufts University and the  University of Illinois at Champaign-Urbana have demonstrated* in mice, using a resistor (as a source of

Activated through permanent stress, immune cells in the brain can cause changes to the brain, resulting in mental disorders, a research team headed by professor Georg Juckel, Medical Director of the Ruhr-Universität Bochum (RUB) LWL university clinic, has found. The research was based on psychoneuroimmunology, the study of the interaction between psychological processes and the nervous

(University College London) The structure of pores found in cell nuclei has been uncovered by a UCL-led team of scientists, revealing how they selectively block certain molecules from entering, protecting genetic material and normal cell functions. The discovery could lead to the development of new drugs against viruses that target the cell nucleus and new ways of delivering gene therapies, say the scientists behind the study.

(Technische Universitaet Muenchen) Ultra-short and extremely strong X-ray flashes, as produced by free-electron lasers, are opening the door to a hitherto unknown world. Scientists are using these flashes to take 'snapshots' of the geometry of tiniest structures, for example the arrangement of atoms in molecules. To improve not only spatial but also temporal resolution further requires knowledge about the precise duration and intensity of the X-ra... More
