Both sides of the brain play a role in processing emotional communication, with the right side stepping in when we focus not on the "what" of an emotional message but rather on how it feels.
By studying blood flow velocity to each side of the brain, Belgian psychologists have opened a window onto the richness and complexity of human emotional communication. Their research appears in the January 2003 issue of Neuropsychology, published by the American Psychological Association (APA).
At Ghent University, Guy Vingerhoets, Ph.D., Celine Berckmoes, M.S., and Nathalie Stroobant, M.S., knew that the left brain is dominant for language, and the right brain is dominant for emotion. But what happens when the brain is faced with emotional language? To find out, the researchers used Transcranial Doppler Ultrasonography (ultrasound), an inexpensive, non-invasive and patient-friendly way to measure blood-flow velocity in the brains left and right middle cerebral arteries -- an indicator of activity level because neurons, to work, need blood-borne glucose and oxygen.

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...
