Live blogs, sources, and objectivity: The contradictions of real-time online reporting

Live blogs, also known as live pages or streams, allow journalists to report on events, including breaking news stories, as they happen. Their prevalence and popularity make them an important format, through which many of the developments in contemporary journalism can be observed and analysed. Using the Egyptian revolution of 2011 as a case study, we carried out a large-scale content analysis across six national UK news publishers, to analyse the differences and similarities between live blogs (n=75), traditional online news articles (n=842), and print articles (n=148). The findings reveal significant differences, for example the extent to which live blogs quote their sources directly and, also, rely on previously-published media reports as a source. The findings demonstrate how, with the expansion of real-time online reporting, journalism may be becoming more transparent yet also more reflexive; prompting, perhaps, reassessments and even redefinitions of media plurality and journalistic objectivity

PSAT: University Amateur Radio Satellite Success Story - Mission Review and Lessons Learned from 18 Months on Orbit

PSAT is the 6th U.S. Naval Academy student engineering Amateur Satellite project since 2001. It remains fully operational and successful for over 18 months in space since the launch in May 2015. PSAT is an example of the academy’s student satellite development projects, designed specifically for the Amateur Satellite Service for the student’s education and self-training at the undergraduate level in the radio/satellite technology. PSAT uses passive radiometric torque from a differential black/white color scheme to induce spacecraft spin on-orbit for passive thermal balancing and consistent charging (in parallel) of individual battery cells which are then used in series to provide appropriate spacecraft bus voltage. This paper summarizes the first 18 months of 58,000 telemetry and 22,000 user downlink packets collected by the worldwide network of volunteer, internet-linked ground stations that all feed the live downlink web page: http://pcsat.findu.com. This summary yields statistics on various telemetry and data types, the total number of users and their worldwide distribution, the total number of ground stations, as well as any satellite-to-satellite link data. The telemetry also reveals the success of the passive spin stabilized attitude and thermal control system including the spacecraft response to the mission loads and the space environment

A Comparative Encyclopedia of DNA Elements in the Mouse Genome

Summary As the premier model organism in biomedical research, the laboratory mouse shares the majority of protein-coding genes with humans, yet the two mammals differ in significant ways. To gain greater insights into both shared and species-specific transcriptional and cellular regulatory programs in the mouse, the Mouse ENCODE Consortium has mapped transcription, DNase I hypersensitivity, transcription factor binding, chromatin modifications, and replication domains throughout the mouse genome in diverse cell and tissue types. By comparing with the human genome, we not only confirm substantial conservation in the newly annotated potential functional sequences, but also find a large degree of divergence of other sequences involved in transcriptional regulation, chromatin state and higher order chromatin organization. Our results illuminate the wide range of evolutionary forces acting on genes and their regulatory regions, and provide a general resource for research into mammalian biology and mechanisms of human diseases
