Visually Provoked Seizures a National Health Problem
The Epilepsy Foundation today issued new recommendations for families on how to limit the risk of seizures triggered by flashing images and certain patterns on television, videogames, computers and other video screens. The recommendations are based upon guidelines in the UK and Japan and are the first published in the US to be based on an expert review of research on photosensitivity (the susceptibility to visual stimulation). The report by Graham Harding of the Clinical Neurophysiology Unit, Aston University, Birmingham, England, and his colleagues, appears in the September issue of the journal Epilepsia, the official journal of the International League Against Epilepsy.
The consensus recommendations, which are published in full on the Epilepsy Foundation website, cover factors such as light intensity, flicker, contrast, duration and pattern, and the technical parameters within these factors that are most likely to provoke seizures in susceptible individuals. Accompanying the report in Epilepsia is an article on the literature and data review conducted for the working group as part of its analysis and recommendations development.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
