Patterns created by the brain’s grid cells, which are believed to guide navigation, are modified by the shape of the environment, according to UCL researchers. This means grid patterns aren’t a universal metric for the brain’s GPS system to measure distance, as previously thought. (more…)
Entry of site in a community tied to 16% increase in HIV
Craigslist’s entry into a market results in a 15.9 percent increase in reported HIV cases, according to research from the University of Minnesota published in the December issue of MIS Quarterly. When mapped at the national level, more than 6,000 HIV cases annually and treatment costs estimated between $62 million and $65.3 million can be linked to the popular website. (more…)
Beyond managing domain names and associated IP addresses, the Internet does not have much governance. Technical experts from around the world met recently in Berlin to discuss options. John Savage, the An Wang Professor of Computer Science at Brown, presented a working paper on approaches to the Internet governance question. (more…)
ANN ARBOR — Facebook remains the most popular social media site, by far, with 71 percent of online adults using the platform, according to a new survey by the Pew Research Center that involves researchers from the University of Michigan School of Information. (more…)
ANN ARBOR — Middle managers often know best when certain practices or products are ripe for change in an organization, but can struggle selling their ideas up the chain of command.
Sue Ashford, professor of management and organizations at the University of Michigan Ross School of Business, details smart steps managers can take to get their ideas considered and implemented in a new Harvard Business Review article. (more…)
Ein Quantennetzwerk benötigt effiziente Schnittstellen, über die Information von Materie auf Licht und umgekehrt übertragen werden kann. Wie dieser Informationstransfer unter Ausnutzung eines kollektiven Quantenphänomens optimiert werden kann, zeigen Innsbrucker Physiker um Rainer Blatt und Tracy Northup nun in der Fachzeitschrift Physical Review Letters.

Google Glass Explorers are using the novel wearable computers for applications ranging from wildlife preservation and museum tours to precision sports training and on-the-go language translation.
For the University of Delaware’s Jingyi Yu, Google Glass is one more device in a “smart health” toolkit that has the potential to profoundly change medical training, diagnostics and treatment. (more…)
Ein Forschungsteam der Universität Kassel entwickelt einen Baustoff, der zugleich eine Solarzelle ist. Wichtige Bestandteile sind leitfähiger Beton und Flüssigkeiten wie beispielsweise Fruchtsäfte. „DysCrete“ soll künftig unter anderem zum Bau von Fassaden dienen und zugleich Sonnenenergie in Strom umwandeln.
„DysCrete“ besteht aus einem speziellen leitfähigen Beton, der mit Lagen aus Titandioxid, einer organischen Flüssigkeit, einem Elektrolyt, Graphit und einer transparenten Oberfläche beschichtet ist. Das Ergebnis ist eine sogenannte Farbstoffsolarzelle, der Beton selber übernimmt dabei die Funktion einer Elektrode. Die Umwandlung der Sonnenenergie in Strom folgt dem Prinzip der Photosynthese. Das Materialsystem ist besonders umweltfreundlich. (more…)
