Using the Living CV to help students take ownership of their learning gain

There is an increasing emphasis on embedding employability skills and experience within the higher education curriculum to address new concepts of ‘learning gain’ and the perceived student demand for a value for money experience. An exploratory study, at a southern university in the UK, found that students articulated an improved work readiness when they were presented the ‘Living CV’, an initiative that connects programme learning outcomes into CV outputs. During 2018, a larger, mixed methods study (n=127) was conducted across all three years of fashion degrees. Students completed a pre and post questionnaire before and after a presentation on the Living CV and their views were further explored in a focus group and interviews. Results found that the Living CV presentation heightened students’ awareness of the applicability of their programme learning to their future employability and how they could use their academic learning outcomes on their CV as a tool to achieve this. The study recommends that personalised and explicit coaching on ‘work literacy’ should be integrated into university programmes at all levels to include the Living CV, discussion about and experience in the world of work, increased employer engagement and preparation for interview

Localization and broadband follow-up of the gravitational-wave transient GW150914

A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially designated G184098 and later given the name GW150914, is described in detail elsewhere. By prior arrangement, preliminary estimates of the time, significance, and sky location of the event were shared with 63 teams of observers covering radio, optical, near-infrared, X-ray, and gamma-ray wavelengths with ground- and space-based facilities. In this Letter we describe the low-latency analysis of the GW data and present the sky localization of the first observed compact binary merger. We summarize the follow-up observations reported by 25 teams via private Gamma-ray Coordinates Network circulars, giving an overview of the participating facilities, the GW sky localization coverage, the timeline, and depth of the observations. As this event turned out to be a binary black hole merger, there is little expectation of a detectable electromagnetic (EM) signature. Nevertheless, this first broadband campaign to search for a counterpart of an Advanced LIGO source represents a milestone and highlights the broad capabilities of the transient astronomy community and the observing strategies that have been developed to pursue neutron star binary merger events. Detailed investigations of the EM data and results of the EM follow-up campaign are being disseminated in papers by the individual teams

Pan-cancer analysis of whole genomes

Cancer is driven by genetic change, and the advent of massively parallel sequencing has enabled systematic documentation of this variation at the whole-genome scale(1-3). Here we report the integrative analysis of 2,658 whole-cancer genomes and their matching normal tissues across 38 tumour types from the Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium of the International Cancer Genome Consortium (ICGC) and The Cancer Genome Atlas (TCGA). We describe the generation of the PCAWG resource, facilitated by international data sharing using compute clouds. On average, cancer genomes contained 4-5 driver mutations when combining coding and non-coding genomic elements; however, in around 5% of cases no drivers were identified, suggesting that cancer driver discovery is not yet complete. Chromothripsis, in which many clustered structural variants arise in a single catastrophic event, is frequently an early event in tumour evolution; in acral melanoma, for example, these events precede most somatic point mutations and affect several cancer-associated genes simultaneously. Cancers with abnormal telomere maintenance often originate from tissues with low replicative activity and show several mechanisms of preventing telomere attrition to critical levels. Common and rare germline variants affect patterns of somatic mutation, including point mutations, structural variants and somatic retrotransposition. A collection of papers from the PCAWG Consortium describes non-coding mutations that drive cancer beyond those in the TERT promoter(4); identifies new signatures of mutational processes that cause base substitutions, small insertions and deletions and structural variation(5,6); analyses timings and patterns of tumour evolution(7); describes the diverse transcriptional consequences of somatic mutation on splicing, expression levels, fusion genes and promoter activity(8,9); and evaluates a range of more-specialized features of cancer genomes(8,10-18).Peer reviewe

Tumor Delivery of Ultrasound Contrast Agents Using Shiga Toxin B Subunit

The present study demonstrates the targeting of ultrasound contrast agents to human xenograft tumors by exploiting the overexpression of the glycolipid Gb3 in neovasculature. To this end, microbubbles were functionalized with a natural Gb3 ligand, the B subunit of the Shiga toxin (STxB). The targeting of Gb3-expressing tumor cells by STxB microbubbles was first shown by flow cytometry and fluorescence microscopy. A significantly higher proportion of STxB microbubbles were associated with Gb3-expressing tumor cells compared to cells in which Gb3 expression was inhibited. Moreover, ultrasonic imaging of culture plates showed a 12 dB contrast enhancement in average backscattered acoustic intensity on the surface of Gb3-expressing cells compared to Gb3-negative cells. Also, a 18 dB contrast enhancement was found in favor of STxB microbubbles compared to unspecific microbubbles. Microbubble signal intensity in subcutaneous tumors in mice was more than twice as high after the injection of STxB-functionalized microbubbles compared to the injection of unspecific microbubbles. These in vitro and in vivo experiments demonstrated that STxB-functionalized microbubbles bind specifically to cells expressing the Gb3 glycolipid. The cell-binding moieties of toxins thus appear as a new group of ligands for angiogenesis imaging with ultrasound
