Nature Communications is an open access, multidisciplinary journal that is dedicated to publishing high-quality research from all areas of the natural sciences, including solid-state electronics and photonics. This presentation will include an overview of publishing in Nature Communications as well as other Nature journals. Recent publications on self-powered devices, triboelectric nanogenerators, energy harvesting, wearable devices, etc. will be highlighted.
On November 17, 2020, Nature Communications published a paper on the role of informal mentorship in the future careers of mentees (AlShebli et al., 2020AlShebli B. Makovi K. Rahwan T. Retraction Note.Nat. Commun. 2020; 11: 6446https://doi.org/10.1038/s41467-020-20617-yCrossref PubMed Scopus (10) Google Scholar). The authors analyzed millions of senior-junior author pairs in millions of papers across ten different disciplines over a century of research. "Informal mentorship" was defined as shared authorship in papers, with the junior scientist (mentee) being less than 7 years from first publication, the senior scientist (mentor) as more, and the two scientists sharing a discipline and belonging to the same US-based institution. Male or female gender was defined based on name. Mentors were identified as either a "Big-shot" or "Hub" based on citation or collaboration strength, respectively. Impact was measured by citation rate. After their analysis, the authors concluded that, "female protégés who remain in academia reap more benefits when mentored by males rather than equally-impactful females." Further, they note, "our findings also suggest that mentors benefit more when working with male protégés rather than working with comparable female protégés, especially if the mentor is female." The authors then raised concern about diversity policies that promote female-female mentorships, on the grounds that not only would they negatively affect the career of the junior scientist, but they would also be detrimental to the later success of the senior. A major shortcoming of the paper is the inadequate definition of mentoring. Mentoring is a multifactorial process that cannot be measured solely on number of publications, order of authorship, or number of future collaborators. Informal mentoring is particularly difficult to measure and can have variable impacts depending upon how often the informal mentoring occurs and its substance. This point was clearly raised in the reviewers' critique. The authors defended their use of "mentorship" by adding a survey (that can only be described as cursory) to provide evidence that they had indeed successfully identified mentees. Notably, fewer than half of the 179 respondents self-identified as student mentees of co-authors. Hence the main topic of the paper is misrepresented; it is not about "mentorship" but "co-publication." The authors examined the impact of female co-publication on mentee success measured by publication citation, an easily obtained metric that can be misleading when considering there is strong evidence for gender discrimination in science. Success in science depends on complex factors that are not considered in this number; we ask, hidden within the millions of datapoints, how many of these women took time off to have children? Or changed their names? How many came to the US on a visa? How many had the choice of "Big-shot" mentors or were selected against in favor of men? How many were hired and promoted by major institutions? How many were subject to either explicit or implicit gender bias? In an egregious oversight, the paper also did not acknowledge that over the century in which the publications were evaluated, women were and are underrepresented in the majority of scientific disciplines, and even fewer held leadership roles. The paper should have acknowledged this historical fact, while also noting that women receive smaller grants and less start-up funding than male peers (Oliveira et al., 2019Oliveira D.F.M. Ma Y. Woodruff T.K. Uzzi B.

Nykiel-Bub L. Selk S.

Scientists' salary data highlight US$18,000 gender pay gap.Nature. 2019; 565: 527Google Scholar), are promoted with reduced frequency, and hold fewer positions of power or influence (Niemeier and González, 2004Niemeier D.A. González C. Breaking into the Guildmasters' Club: What We Know about Women Science and Engineering Department Chairs at AAU Universities.NWSA Journal. 2004; 16: 157-171Crossref Google Scholar). While there are now efforts to redress this imbalance, the paper merely highlights and confirms the long-existing gender disparity problem. Rather than using their analysis as a call for change, the paper is reactionary in its evaluation and response. This fuels the very prejudices that we must fight against. An insight into the biased conceptual framework of the paper is shown by the authors' note, "A Closer Look at the Protégés' Innate Ability," in which they write, "mentors with higher prior impact are more capable of selecting talented protégés, especially since these mentors are more likely to be good judges of innate ability in their area of expertise." That the authors believe a successful scientist will be born with scientific ability, and consider that successful mentors can recognize it, should make us all question the premises of the study. Within hours of publication, reactions erupted on the internet, most expressing concerns about the validity of the conclusions. Many also criticized the editorial process that had apparently ignored valid critique from the reviewers that had not resulted in significant revision of the conclusions. Some responders were reminded of Harvard University president Larry Summers who in 2005 suggested that differences in innate aptitude rather than discrimination were more likely to be to blame for the failure of women to advance in scientific careers. In 2006 in a Commentary in Nature (Vol 442|13 July 2006) the (late) brilliant transgender neuroscientist Ben Barres refuted Summers' position and said, "It was only [through] changing sex at the age of 40 and experiencing life from the vantage of a man that I finally came to be fully aware of these barriers." Barres documented with careful data analysis the prejudice that has led to the dearth of women in science. This paper disappointingly demonstrates how much there is still to improve. That the authors had the hubris to suggest policy changes because of this study is quite astonishing, and that the editors published it without regard to consequences is a grave misstep. It was irresponsible to use this flawed paper to make recommendations about organizational policy changes without broader consideration of different findings and disciplinary viewpoints and the time context. Following through on policy changes recommended by the authors should be considered harmful to women in science and their advancement. The paper was retracted by the authors on December 21, 2020 (AlShebli et al., 2020AlShebli B. Makovi K. Rahwan T. Retraction Note.Nat. Commun. 2020; 11: 6446https://doi.org/10.1038/s41467-020-20617-yCrossref PubMed Scopus (10) Google Scholar), acknowledging criticisms in relation to the use of co-authorship as a measure of mentorship while stating nevertheless that they "believe that all the key findings of the paper with regards to co-authorship between junior and senior researchers are still valid." We find this response unacceptable: the reasons for authorship positions on papers are also extremely complex and often disadvantage women who are not prepared or not able to dispute the decision of the senior author. Moreover, their retraction did not acknowledge their unjustified conclusions relating female gender to career success and policy suggestions. Given our leadership roles in the International Society for Stem Cell Research, we are speaking out about the importance of eliminating inequities that young scientists face throughout their careers. Valuing and recognizing the unique career paths of a diverse talent pool combined with an institutional culture that supports and rewards inclusive excellence in mentoring practices and career advancement should be the core focus of institutional policies. This paper should be a call to arms to redress bias against women in science that has been systemic for decades, not used to insinuate that women mentors are detrimental to scientific progress and career advancement. We need to stop blaming the victim and do all we can to make significant changes for gender equality.

PURPOSE: To examine the frequency and nature of postinterview communications between programs and applicants during the National Resident Matching Program (NRMP) Main Residency Match. METHOD: The authors surveyed senior medical students at seven U.S. medical schools about postinterview communications with residency programs during the 2010 Match and analyzed the data. RESULTS: The response rate was 68.2% (564/827). Among respondents, 86.4% reported communicating with residency programs. Most (59.9%) reported telling more than one program they would rank it highly; 1.1% reported telling more than one they would rank it first. Students reported that programs told them they would be "ranked to match" (34.6%), be "ranked highly" (52.8%), or "fit well" (76.2%). Almost one-fifth (18.6 %) reported feeling assured by a program that they would match there but did not despite ranking that program first; 23.4% reported altering their rank order list based on communications with programs. In multivariate analysis, applicants to more competitive specialties were less likely to report being told they would be "ranked to match" (relative risk [RR] 0.72, 95% confidence interval [CI] 0.52-0.99). Applicants were more likely to report being told that they would be "ranked to match" if they received honors in the specialty clerkship (RR 1.39, 95% CI 1.10-1.77) or were members of Alpha Omega Alpha (RR 1.72, 95% CI 1.37-2.17). CONCLUSIONS: Reports of nonbinding communications with programs were frequent. Students should be advised to interpret any comments made by programs cautiously. Reported violations of the NRMP's Match Participation Agreement were uncommon.
Abstract The numerous policy changes taking place following the passage of the Telecommunications Act of 1996 necessitate an examination of the nature of communications regulation. Specifically, it is necessary to reexamine whether the prevailing analytic perspective adequately accounts for the fundamental differences between communications regulation and the regulation of other industries. This article outlines three fundamental differences and discusses their implications for effective communications policy analysis.
Scientists have zoomed in on how phosphoric acid moves electrical charges so efficiently in both biology and technology。 By freezing a key molecular pair to extremely low temperatures, they found it forms just one stable structure—contrary to predictions。 This structure relies on a specific hydrogen-bond network that may be universal in similar sys
Six of 85 patients (7%) with alcoholic liver disease undergoing transhepatic portal pressure measurement had either stagnant (3 patients) or reversed (3 patients) portal blood flow documented by gentle hand injection of 1 to 2 ml of angiographic contrast. Portal blood flow was uniformly hepatopetal in 24 patients with nonalcoholic liver disease. Recurrent spontaneous hepatic encephalopathy and sodium retention occurred in 4 of 6 patients with stagnant or reversed portal flow; gastrointestinal bleeding was not seen. Standard laboratory tests of liver function were widely variable. Net portal pressure was lower in this group than in patients with alcoholic liver disease and forward portal flow (9.2 +/- 2.6 vs. 15.6 +/- 4.1 mm Hg, p less than 0.001). Wedged hepatic vein pressure was 1 to 7 mm Hg higher than portal vein pressure in patients with reversed portal flow. The arterioportal extraction of bile acid was calculated from the difference in concentration between artery and portal vein, and total functional hepatic blood flow was calculated from the hepatic extraction and systemic clearance of indocyanine green. Extraction was 0%, and hepatic blood flow was 0.469 liter per min in a patient with hepatofugal portal flow and recurrent encephalopathy. Extraction was 20%, and hepatic blood flow was 4.014 liters per min in a patient who had never had encephalopathy. These data indicate that arterioportal communications may be sinusoidal or presinusoidal in patients who lose forward portal flow and that the amount of flow in the arterioportal circuit, together with its efficiency, largely determine the clinical outcome.

The promotional mix has been used for many years by a vast number of teachers and authors in order to help explain the promotional activities undertaken by organisations. Considered to be one the 4Ps of the marketing mix, promotion has remained a central element in the way this part of the marketing syllabus is taught. Drawing on the literature and developments in professional practise, this paper explores developments in marketing theory, examines some of the changes in the ways audiences and organisations communicate and considers the impact these have had on the promotional mix. In order to assess these changes two underpinning concepts, relational theory and the resource based view of the firm, are utilised. The paper argues that the promotional mix is no longer a viable interpretation and teaching tool. A new marketing communications mix, MCM 2 , based on two key elements, is presented. The first considers message content and refers primarily to the presentation of the message. The second concerns the media mix, one that incorporates a revised classification of direct and indirect media. It is argued that the new mix is a more accurate reflection of contemporary practise, and more suitable for teaching and educational purposes.

After two centuries of failed attempts, scientists have finally grown dolomite in the lab, cracking a long-standing geological puzzle。 They discovered that the mineral’s growth stalls because of tiny defects—but in nature, those flaws get washed away over time。 By mimicking this process with precise simulations and electron beam pulses, the team ac
Scientists have proposed a surprising new way to detect gravitational waves—by observing how they change the light emitted by atoms。 These waves can subtly shift photon frequencies in different directions, leaving behind a detectable signature。 The effect doesn’t change how much light atoms emit, which is why it’s gone unnoticed until now
Physicists have taken a major step toward using AI not just to analyze data, but to uncover entirely new laws of nature。 By combining a specially designed neural network with precise 3D tracking of particles in a dusty plasma—a strange “fourth state of matter” found from space to wildfires—the team revealed hidden patterns in how particles interact
