In a study of third graders, children with a television in their bedrooms had lower scores on standardized tests while children with access to a home computer had higher scores, researchers report in the July issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.
U.S. households with children have an average of 2.8 television sets and 97 percent of those households have at least one video cassette recorder (VCR) or DVD player, according to background information in the article. More than two thirds of households with children have at least one computer and more than half (53 percent) have home Internet access. While substantial evidence exists to show that people who use media more heavily are at greater risk for obesity and aggressive behavior, the relationship between media and academic achievement is less clear, the researchers suggest.
Dina L. G. Borzekowski, Ed.D., of the Johns Hopkins Bloomberg School of Public Health, Baltimore, and Thomas N. Robinson, M.D., M.P.H., of Stanford University, Stanford, Calif., compared students’ third grade tests scores on the Stanford Achievement Test (mathematics, reading and language arts sections) in the spring of 2000 with data on television and computer use collected through student surveys and telephone interviews with parents for children in six elementary schools in the fall of 1999 and the spring of 2000. Three hundred forty-eight students completed the survey. The children had an average age of 8.5 years, were ethnically diverse and evenly divided between the sexes (53 percent girls).

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
