New findings from researchers at Georgetown University Medical Center in collaboration with Wake Forest University School of Medicine have shown that there is hope for individuals suffering a life-long history of reading problems. Using brain imaging technology the research group showed how the adult dyslexic brain responds to a specific phonological-based reading intervention program responsible for reading skill improvement. Published in the October 28 issue of the Journal Neuron, this is the first research study to examine the brain systems related to successful phonological-based instruction in dyslexic adults.
"Reading is one of the most important skills we learn – it affects virtually every aspect of a persons life," said Dr. Guinevere Eden, associate professor of pediatrics, director of Georgetown Universitys Center for the Study of Learning, and lead author of the study. "Despite the fact that the majority of individuals with dyslexia are adults, little is known about the biological basis of how they can improve their reading skills. We need to understand the neural mechanisms behind these research-based reading instructions so that we can achieve a deeper understanding of precisely how these interventions work. Our findings suggest that the brain mechanisms used by adult dyslexics might be different from those observed when young children undergo remediation, a strong indication that there will never be a one size fits all approach to helping dyslexics become proficient readers."
Using functional magnetic resonance imaging (fMRI), nineteen dyslexic adults underwent brain imaging twice. Half of the group completed an eight-week, phonological intervention program between the two scans, with the rest of the dyslexics serving as a comparison group.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
