An international research team led by Drs. Berge Minassian and Stephen Scherer of The Hospital for Sick Children (HSC) and the University of Toronto (U of T) has identified a gene responsible for the most severe form of teenage-onset epilepsy, known as Lafora disease (LD). The discovery is reported in the September issue of the scientific journal Nature Genetics.
"Epilepsy is one of the most common neurological disorders affecting over 40 million people worldwide," said Dr. Berge Minassian, one of the studys senior authors, an HSC neurologist and scientist, and an assistant professor in the Department of Paediatrics at U of T. "Lafora disease is one form of epilepsy that occurs during early adolescence and is characterized by seizures and progressive neurological degeneration. Death usually occurs within a decade of the first symptoms."
Fifty years of investigation led doctors to suspect that Lafora disease was caused by problems with carbohydrate metabolism in the brain. Beyond this, however, the fundamental defect triggering the malfunction was unknown. In 1998, the HSC team identified the first gene implicated in Lafora disease, called EPM2A.

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,...
