EDITORIAL
Gregory E Kaebnick
This issue of the Hastings Center Report (May-June 2017) features a couple of interesting takes on the governance challenges of emerging technologies. In an essay on the National Academies of Science, Engineering, and Medicine report published this February on human germ-line gene editing, Eric Juengst, a philosopher at the University of North Carolina, argues that the NASEM committee did not manage to rethink the rules. Juengst reaches what he calls an "eccentric conclusion": "The committee's 2017 consensus report has been widely interpreted as 'opening the door' to inheritable human genetic modification and holding a line against enhancement interventions...

In 2015, a flourish of "alarums and excursions" by the scientific community propelled CRISPR/Cas9 and other new gene-editing techniques into public attention. At issue were two kinds of potential gene-editing experiments in humans: those making inheritable germ-line modifications and those designed to enhance human traits beyond what is necessary for health and healing. The scientific consensus seemed to be that while research to develop safe and effective human gene editing should continue, society's moral uncertainties about these two kinds of experiments needed to be better resolved before clinical trials of either type should be attempted...

What does it take to convert a heap of sequencing data into a publishable result? First, common tools are employed to reduce primary data (sequencing reads) to a form suitable for further analyses (i.e., the list of variable sites). The subsequent exploratory stage is much more ad hoc and requires the development of custom scripts and pipelines, making it problematic for biomedical researchers. Here, we describe a hybrid platform combining common analysis pathways with the ability to explore data interactively...

BACKGROUND: Glioblastoma represents an archetypal example of a heterogeneous malignancy. To understand the diverse molecular consequences of this complex tumor ecology, we analyzed RNA-seq data generated from commonly identified intra-tumoral structures in glioblastoma enriched using laser capture microdissection. METHODS: Raw gene-level fragments per kilobase of transcript per million reads mapped (FPKM) values and the associated clinical data were acquired from the publically available Ivy GAP database and analyzed using MetaboAnalyst (v...

OBJECTIVE: As obesity rates continue to climb in America, much of the blame has fallen on the high-calorie meals at popular chain restaurants. Many restaurants have responded by offering "healthy" menu options. Yet menus' descriptions of healthy options may be less attractive than their descriptions of less healthy, standard options. This study examined the hypothesis that the words describing items in healthy menu sections are less appealing than the words describing items in standard menu sections...

A quantitative content analysis examined the portrayal of schizophrenia in eight of the most read online news publications in the United States. The analysis documented the prevalence of stigma frames, which communicate stereotypes concerning schizophrenia, and stigma-challenge frames, which contradict stereotypes, in 558 articles related to schizophrenia. The study also examined the relationship between media framing and reader commentary, including the likelihood of readers posting stigmatizing comments, stigma-challenging comments, and comments in which they disclosed personal experience with mental illness...

BACKGROUND: Watercress (Nasturtium officinale R. Br.) is an aquatic herb species that is a rich source of secondary metabolites such as glucosinolates. Among these glucosinolates, watercress contains high amounts of gluconasturtiin (2-phenethyl glucosinolate) and its hydrolysis product, 2-phennethyl isothiocyanate, which plays a role in suppressing tumor growth. However, the use of N. officinale as a source of herbal medicines is currently limited due to insufficient genomic and physiological information...

In a 1986 article (Am J Epidemiol. 1986;124(6):903-915), Keys et al. described and discussed 15-year findings from 15 cohorts of the Seven Countries Study (SCS), the first systematic study of diet, risk characteristics, disease-specific death rates, and their ecologic and individual associations both among and within whole populations of working men in regions with contrasting traditional diets. The SCS findings included 30-fold cohort differences in rates of death from coronary heart disease and 3-fold differences in rates of death from all causes, along with strong ecologic associations among diet, risk factors, and disease rates...

First impressions based on facial appearance predict many important social outcomes. We investigated whether such impressions also influence the communication of scientific findings to lay audiences, a process that shapes public beliefs, opinion, and policy. First, we investigated the traits that engender interest in a scientist's work, and those that create the impression of a "good scientist" who does high-quality research. Apparent competence and morality were positively related to both interest and quality judgments, whereas attractiveness boosted interest but decreased perceived quality...

BACKGROUND: Despite the economic importance of sugarcane in sugar and bioenergy production, there is not yet a reference genome available. Most of the sugarcane transcriptomic studies have been based on Saccharum officinarum gene indices (SoGI), expressed sequence tags (ESTs) and de novo assembled transcript contigs from short-reads; hence knowledge of the sugarcane transcriptome is limited in relation to transcript length and number of transcript isoforms. RESULTS: The sugarcane transcriptome was sequenced using PacBio isoform sequencing (Iso-Seq) of a pooled RNA sample derived from leaf, internode and root tissues, of different developmental stages, from 22 varieties, to explore the potential for capturing full-length transcript isoforms...

Two models of attention deficit hyperactivity disorder (ADHD) coexist: the biomedical and the psychosocial. We identified in nine French newspapers 159 articles giving facts and opinions about ADHD from 1995 to 2015. We classified them according to the model they mainly supported and on the basis of what argument. Two thirds (104/159) mainly supported the biomedical model. The others either defended the psychodynamic understanding of ADHD or voiced both models. Neurological dysfunctions and genetic risk factors were mentioned in support of the biomedical model in only 26 and eight articles, respectively...

Computer-aided reading (CAR) of medical images is becoming increasingly common, but few studies exist for CAR in tuberculosis (TB). We designed a prospective study evaluating CAR for chest radiography (CXR) as a triage tool before Xpert MTB/RIF (Xpert).Consecutively enrolled adults in Dhaka, Bangladesh, with TB symptoms received CXR and Xpert. Each image was scored by CAR and graded by a radiologist. We compared CAR with the radiologist for sensitivity and specificity, area under the receiver operating characteristic curve (AUC), and calculated the potential Xpert tests saved...

Comparing lifestyle of people remaining sedentary during longer periods of their life with those favourably changing their behaviour can provide cues to optimize interventions targeting sedentary behaviour. The objective of this study was to determine lifestyle predictors of sustained leisure time sedentary behaviour and assess whether these predictors were dependent on gender, age, socioeconomic position and occupational sedentary behaviour. Data from a large longitudinal population-based cohort of adults (aged 18-97years) in Stockholm responding to public health surveys in 2010 and 2014 were analysed (n=49,133)...

Over the past two decades, quality of life has become an essential preoccupation in the care of patients. Many measuring instruments are available to assess physical, psychological and social quality of life. These tools allow healthcare professionals to determine the best quality of their patients. However, the quality of life for the pregnant woman seems to be little studied. This article presents the results of a bibliographic review of publications between 2005 and 2015 - referenced in PUBMED and COCHRANE - on the quality of life of pregnant women giving birth after the 22nd week of amenorrhea...

The first stable version of the Proteomics Standards Initiative mzIdentML open data standard (version 1.1) was published in 2012 - capturing the outputs of peptide and protein identification software. In the intervening years, the standard has become well supported in both commercial and open software, as well as a submission and download format for public repositories. Here we report a new release of mzIdentML (version 1.2) that is required to keep pace with emerging practice in proteome informatics. New features have been added to support: (i) scores associated with localization of modifications on peptides; (ii) statistics performed at the level of peptides; (iii) identification of cross-linked peptides; and (iv) support for proteogenomics approaches...

Influenza A virus mRNAs are transcribed by the viral RNA-dependent RNA polymerase in the cell nucleus before being exported to the cytoplasm for translation. Segment 7 produces two major transcripts: an unspliced mRNA that encodes the M1 matrix protein and a spliced transcript that encodes the M2 ion channel. Export of both mRNAs is dependent on the cellular NXF1/TAP pathway but it is unclear how they are recruited to the export machinery or how the intron-containing but unspliced M1 mRNA bypasses the normal quality control checkpoints...
