A recent study published in Epilepsia, the official journal of the International League Against Epilepsy (ILAE), indicates that people who have uncontrolled seizures on the left side of their brains are more likely to have learning disabilities, in comparison to people who have seizures on the right side of their brains. Epilepsy, a neurological disorder associated with recurrent seizures, affects 0.5% to 1% of the population. In theU.S., about 2.5 million people have this disorder and about 9% of Americans will have at least one seizure during their lives.
In the study conducted at the LSU Epilepsy Center of Excellence, adult patients of normal intelligence with either left temporal lobe epilepsy (TLE) or right TLE were evaluated with reading comprehension, written language, and calculation tests. The Center researchers found that 75% of patients with left TLE had one or more learning disabilities. This was found in only 10% of those with right TLE. Additionally, those with left TLE reported higher rates of literacy and/or career development problems, such as a history of special education, repeating grades, or disrupted educational progress.
According to author Grant Butterbaugh, Ph.D., Director of the LSU Epilepsy Center’s Neuropsychology Program, and his colleagues, left temporal lobe seizure onset was associated with higher risk of learning disabilities, consistent with the disruptive impact of medically well treated but uncontrolled seizures in the "language dominant" side of the brain.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
