An intermediate-depth (1751 m) ice core was drilled at the South Pole between 2014 and 2016 using the newly designed US Intermediate Depth Drill. The South Pole ice core is the highest-resolution interior East Antarctic ice core record that extends into the glacial period. The methods used at the South Pole to handle and log the drilled ice, the procedures used to safely retrograde the ice back to the National Science Foundation Ice Core Facility (NSF-ICF), and the methods used to process and sample the ice at the NSF-ICF are described. The South Pole ice core exhibited minimal brittle ice, which was likely due to site characteristics and, to a lesser extent, to drill technology and core handling procedures.

The emergence of punk in Britain (1976–1978) is recalled and documented as a moment of rebellion, one in which youth culture was seen to challenge accepted values and forms of behaviour, and to set in motion a new kind of cultural politics. In this article we do two things. First, we ask how far punk's challenge extended. Did it penetrate those political, cultural and social elites against which it set itself? And second, we reflect on the problem of recovering the history and politics of moments such as punk, and on the value of archives to such exercises in recuperation. In pursuit of both tasks, we make use of a wide range of historical sources, relying on these rather than on retrospective oral or autobiographical accounts. We set our findings against the narratives offered by both subcultural and mainstream histories of punk. We show how punk's impact on elites can be detected in the rhetoric of the popular media, and in aspects of the practice of local government and the police. Its impact on other elites (e.g. central government or the monarchy) is much harder to discern. These insights are important both for enriching our understanding of the political significance of punk and for how we approach the historical record left by popular music.

In this paper, we consider the Leveson inquiry's use of a narrative device – the policy cycle – to justify the need for a break with the past. We challenge that narrative, which runs through much of the literature, and posit a more nuanced and complex account of the politics and history of press inquiries, drawing upon the political science literature. We then reflect upon the implications of our findings for the future of press regulation.

Tucked away on the b-side of the Sex Pistols’ third single, ‘Pretty Vacant’ (1977), is a cover version of The Stooges’ ‘No Fun’. The song had long been a staple of the Pistols’ live set; on record, however, Johnny Rotten chose to open the track with a diatribe against those attempting to imbue the punk culture he helped instigate with broader socio-economic, cultural or political implications. ‘Here we go now’, he snarled, ‘a sociology lecture, with a bit of psychology, a bit of neurology, a bit of fuckology’.

Electoral rules have the potential to affect the size and composition of the voting public. Yet scholars disagree over whether requiring voters to register well in advance of Election Day reduces turnout. We present a new approach, using web searches for “voter registration” to measure interest in registering, both before and after registration deadlines for the 2012 U.S. presidential election. Many Americans sought information on “voter registration” even after the deadline in their state had passed. Combining web search data with evidence on the timing of registration for 80 million Americans, we model the relationship between search and registration. Extrapolating this relationship to the post-deadline period, we estimate that an additional 3–4 million Americans would have registered in time to vote, if deadlines had been extended to Election Day. We test our approach by predicting out of sample and with historical data. Web search data provide new opportunities to measure and study information-seeking behavior.

Four accelerator mass spectrometry (AMS) facilities undertook an interlaboratory exercise designed to examine the reliability and reproducibility of radiocarbon determinations on bone by dating a sample of elk (Alces alces) from Miesenheim IV. This specimen is derived from a secure geological context directly beneath the Laacher See tephra, which provides a precise terminus ante quern of ∼11,060 yr BP (∼13,050 cal yr BP). Regrettably, the results of the intercomparison exercise were complicated by evident contamination of the bone sample by exogenous organic material. This contaminant, probably humic acid, resulted in a wide span of ages (10,010 ± 30 to 11,100 ± 45 BP). The only method that yielded an accurate determination, consistent with the age of the tephra, was Oxford's single amino acid technique, which targets hydroxyproline. An acid hydrolysis step seems to have been crucial in breaking the bonds between the bone collagen and the contaminant.
