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.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
