Addressing a persistent debate in the field of dyslexia research, scientists at the University of Wisconsin-Madison and the University of Southern California (USC) have disproved the popular theory that deficits in certain visual processes cause the spelling and reading woes commonly suffered by dyslexics.
Rather, a more general problem in basic sensory perception may be at the root of the learning disorder, the scientists report today (May 29, 2005) in the journal Nature Neuroscience. The work suggests new ways to identify dyslexics and to assess the many unevaluated techniques teachers use to help dyslexics in the classroom.
Misfiring neurons perhaps make it difficult for dyslexics to pick out relevant visual and auditory cues from the expanse of surrounding sounds and patterns, or "noise"; it is this inability that may bear heavily on how easily a child can read, says lead author Anne Sperling, who conducted the research as a USC graduate student, alongside co-author Mark Seidenberg, a UW-Madison psychology professor who left USC in 2001.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
