TL;DR: This review outlines several studies and data concerning the genetics and other important factors in the susceptibility risk to develop obesity, and focuses in the evolutionary hypotheses that have been proposed trying to explain how natural selection favored the spread of genes that increase the risk for an obese phenotype and how this predisposition to obesity evolved.
Abstract: It is well-known that obesity is a complex multifactorial and heterogeneous condition with an important genetic component. Recently, major advances in obesity research emerged concerning the molecular mechanisms contributing to the obese condition. This review outlines several studies and data concerning the genetics and other important factors in the susceptibility risk to develop obesity. Based in the genetic etiology three main categories of obesity are considered: monogenic, syndromic, and common obesity. For the monogenic forms of obesity, the gene causing the phenotype is clearly identified, whereas for the common obesity the loci architecture underlying the phenotype is still being characterized. Given that, in this review we focus mainly in this obesity form, reviewing loci found until now by genome-wide association studies related with the susceptibility risk to develop obesity. Moreover, we also detail the obesity-related loci identified in children and in different ethnic groups, trying to highlight the complexity of the genetics underlying the common obese phenotype. Importantly, we also focus in the evolutionary hypotheses that have been proposed trying to explain how natural selection favored the spread of genes that increase the risk for an obese phenotype and how this predisposition to obesity evolved. Other factors are important in the obesity condition, and thus, we also discuss the epigenetic mechanisms involved in the susceptibility and development of obesity. Covering all these topics we expect to provide a complete and recent perspective about the underlying mechanisms involved in the development and origin of obesity. Only with a full understanding of the factors and mechanisms contributing to obesity, it will be possible to provide and allow the development of new therapeutic approaches to this condition.

TL;DR: Findings showed that both men and women with sexual dysfunction had significantly less positive emotional reactions to automatic thoughts during sexual activity, congruent with recent studies indicating that emotions related to depressed affect as opposed to negative emotions were stronger correlates of sexual dysfunction.
Abstract: The present study investigated the differences in emotional response to automatic thoughts presented during sexual activity between sexually functional and dysfunctional men and women. A total of 376 participants (160 women and 120 men without sexual problems and 47 women and 49 men with a DSM-IV-TR diagnosis of sexual dysfunction) completed the Sexual Modes Questionnaire (SMQ male and female versions; P. J. Nobre & J. Pinto-Gouveia, 2000) and measures of sexual functioning: The International Index of Sexual Function (IIEF; R. C. Rosen et al., 1997), and The Female Sexual Function Index (FSFI; R. C. Rosen et al., 2000). The SMQ is a combined measure constituted by three interdependent subscales: Automatic Thought subscale (AT), Emotional Response subscale (ER), and Sexual Response subscale (SR). Emotions were assessed by the ER subscale, where participants endorsed emotional reactions (worry, sadness, disillusion, fear, guilt, shame, anger, hurt, pleasure, satisfaction) to a list of automatic thoughts (AT subscale) that may occur during sexual activity. Results showed that both men and women with sexual dysfunction had significantly less positive emotional reactions to automatic thoughts during sexual activity. Sexually dysfunctional men had significantly more emotions of sadness, disillusion, and fear, and less pleasure and satisfaction, compared to men without sexual problems. Women with sexual dysfunction had significantly less pleasure and satisfaction, and more sadness, disillusion, guilt, and anger. Findings were congruent with recent studies indicating that emotions related to depressed affect (sadness, disillusion, lack of pleasure) as opposed to negative emotions (mostly related to anxiety) were stronger correlates of sexual dysfunction.

TL;DR: A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139 fb^{-1} of proton-proton collisions at sqrt[s]=13TeV recorded with the ATLAS detector.
Abstract: A search for heavy neutral Higgs bosons is performed using the LHC Run 2 data, corresponding to an integrated luminosity of 139 fb^{-1} of proton-proton collisions at sqrt[s]=13 TeV recorded with the ATLAS detector. The search for heavy resonances is performed over the mass range 0.2-2.5 TeV for the τ^{+}τ^{-} decay with at least one τ-lepton decaying into final states with hadrons. The data are in good agreement with the background prediction of the standard model. In the M_{h}^{125} scenario of the minimal supersymmetric standard model, values of tanβ>8 and tanβ>21 are excluded at the 95% confidence level for neutral Higgs boson masses of 1.0 and 1.5 TeV, respectively, where tanβ is the ratio of the vacuum expectation values of the two Higgs doublets.
