Benefits and problems are related to developmental stages, family context
A consortium of researchers has reported that very young children’s interactions with TV and computers are a mixed bag of opportunities and cautions, while teenagers’ Internet use has changed so much that the myths of several years ago need to be debunked. Said Amy Sussman, program manager for the National Science Foundation (NSF), which funds the five-site Children’s Digital Media Center (CDMC), "Reaping the benefits of various media while avoiding pitfalls is no easy task. Parents and policymakers need to inform their decisions about whether and how to guide their children’s media use through scientific knowledge. Different developmental stages call for different strategies. These and other research studies can help create needed guidance for children at all ages."
Scientists affiliated with five locations of the center reported the results of 14 research studies in special issues of The American Behavioral Scientist and the Journal of Applied Developmental Psychology. Editors for the special issues included Sandra L. Calvert from Georgetown University, who heads up the CDMC; Patricia M. Greenfield, who leads the research at UCLA; Elizabeth A. Vandewater, who heads the research at the University of Texas-Austin, and Ellen Wartella, who leads the research at the University of California-Riverside. Barbara J. O’Keefe, who heads the research at Northwestern University, contributed to the research articles.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
