A team headed by scientists at Northwestern University, using functional magnetic resonance imaging (fMRI), has shown how to visualize the human brain as a massive, interacting, complex network governed by a few underlying dynamic principles.
The research opens fascinating possibilities for future basic and applied studies to investigate the dynamics of brain states, particularly in cases of dysfunction -- such as schizophrenia, Alzheimers disease and chronic pain -- without requiring external markers.
Dante R. Chialvo, research associate professor of physiology at Northwestern University Feinberg School of Medicine, led the study, which appeared in the Dec. 31 online issue of the journal Physical Review Letters. The research group included scientists from the IBM T.J. Watson Research Center, Yorktown Heights, N.Y., and the University of Islas Baleares, Mallorca, Spain.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
