Like Fish on Waves: Electrons Go Surfing

Published: September 22, 2011.

Physicists at the RUB, working in collaboration with researchers from Grenoble and Tokyo, have succeeded in taking a decisive step towards the development of more powerful computers. They were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them using a sound wave, and then to transport it to the neighbouring QD. A single electron "surfs" thus from one quantum dot to the next like a fish on a…

Susceptibility for Relapsing Major Depressive Disorder Can Be Calculated
Selver Demic and his colleagues from the Mercator Research Group have set out to find out more about the causes of depression. "Approx. 20 per cent of the population will suffer a de-pressive episode in the course of their lives," says Demic. "This cohort of 20 per cent includes people who will never again experience any problems after that one-time episode is over. The others, however, will suffer repeatedly or chronically under the disorder, despite taking appropriate medication. We want to use our…

A Glimpse into the 3-D Brain: How Memories Form
The way neurons are interconnected in the brain is very complicated. This holds especially true for the cells of the hippocampus. It is one of the oldest brain regions and its form resembles a see horse (hippocampus in Latin). The hippocampus enables us to navigate space securely and to form personal memories. So far, the anatomic knowledge of the networks inside the hippocampus and its connection to the rest of the brain has left scientists guessing which information arrived where and when.

Low-birth-weight Children Are Particularly Vulnerable to Environmental Influences
Low birth weight children are more vulnerable to environmental influences than infants born with normal weight. When brought up with a great deal of sensitivity, they will be able to catch up in school, but on average they will not become better students than normal birth weight children. This result, provided by an international psychologist team, has confirmed the so-called diathesis-stress model of development for low birth weight populations. The researchers report their findings in the Journal of Child Psychology and Psychiatry. …

Green Light for Clever Algae
The researchers headed by Prof Dr Nicole Frankenberg-Dinkel have been the first ones to reveal similarities and differences in the assembly of the light-harvesting machinery of the cryptophyte Guillardia theta compared to cyanobacteria and red algae. The publication of their results in the current issue of "The Journal of Biological Chemistry" is among the two per cent of the publications that were selected as "Paper of the week".
