As the cost of sequencing continues to decrease and the amount of sequence data generated grows, new paradigms for data storage and analysis are increasingly important. The relative scaling behavior of these evolving technologies will impact genomics research moving forward.

The relationship between treatment progress (as rated by both clients and therapists) and real relationship (also rated by both clients and therapists) was decomposed into between-therapist and within-therapist (between-client) effects and analyzed using the actor-partner interdependence model. We reanalyzed a subset of the data, 12 therapists and 32 clients, from Gelso et al.’s (2012) study of brief, theoretically diverse outpatient treatment. Consistent with and extending previous research, clients whose therapists provided higher average levels of client-perceived real relationship across the clients treated by a given therapist had better progress ratings from both themselves and their therapists. Within each therapist’s caseload, differences between clients in client- or therapist-rated real relationship were unrelated to either client- or therapist-rated outcome. Clients whose therapists provided higher average levels of therapist-perceived real relationship, across the clients treated by the therapist, had worse progress ratings from the therapists. The results provide additional evidence for the importance of between-therapist differences in therapeutic relationship qualities, both client and therapist rated.

Self-deception is widespread in humans even though it can lead to disastrous consequences such as airplane crashes and financial meltdowns. Why is this potentially harmful trait so common? A controversial theory proposes that self-deception evolved to facilitate the deception of others. We test this hypothesis in the real world and find support for it: Overconfident individuals are overrated by observers and underconfident individuals are judged by observers to be worse than they actually are. Our findings suggest that people may not always reward the more accomplished individual but rather the more self-deceived. Moreover, if overconfident individuals are more likely to be risk-prone then by promoting them we may be creating institutions, including banks and armies, which are more vulnerable to risk. Our results reveal practical solutions for assessing individuals that circumvent the influence of self-deception and can be implemented in a range of organizations including educational institutions.

Non-celiac wheat sensitivity (WS) is considered a new clinical entity. An increasing percentage of the general population avoids gluten ingestion. However, the real existence of this condition is debated and specific markers are lacking. Our aim was thus to demonstrate the existence of WS and define its clinical, serologic, and histological markers.

Rising global demand for meat will result in increased environmental pollution, energy consumption, and animal suffering. Cultured meat, produced in an animal-cell cultivation process, is a technically feasible alternative lacking these disadvantages, provided that an animal-component-free growth medium can be developed. Small-scale production looks particularly promising, not only technologically but also for societal acceptance. Economic feasibility, however, emerges as the real obstacle.

Objectives. We examined the association between state-level foreclosure and suicide rates from 2005 to 2010 and considered variation in the effect of foreclosure on suicide by age. Methods. We used hybrid random- and fixed-effects models to examine the relation between state foreclosure rates and total and age-specific suicide rates from 2005 to 2010 (n = 306 state-years). Results. Net of other factors, an increase in the within-state total foreclosure rate was associated with a within-state increase in the crude suicide rates (b = 0.04; P < .1), and effects were stronger for the real estate-owned foreclosure rate (b = 0.16; P < .05). Analysis of age-specific suicide rates indicated that the effects were strongest among the middle-aged (46-64 years: total foreclosure rate, b = 0.21; P < .001; real estate-owned foreclosure rate, b = 0.83; P < .001). Rising home foreclosure rates explained 18% of the variance in the middle-aged suicide rate between 2005 and 2010. Conclusions. The foreclosure crisis has likely contributed to increased suicides, independent of other economic factors associated with the recession. Rising foreclosure rates may be partially responsible for the recent uptick in suicide among middle-aged adults.

Muscle lesions account for one-third of sport-related injuries, thus representing a substantial problem for both players and their teams. The use of platelet-rich plasma (PRP) injections is rapidly growing in clinical practice, prompted by an unmet clinical need with a large commercial market. However, after early reports of positive preliminary experience, higher quality studies recently questioned the real benefit provided by PRP injections to promote muscle healing and return to sport.

Placebo analgesia, reductions in pain following administration of an inert treatment, is a well-documented phenomenon. We report the first demonstration that placebo analgesia can be experienced when a sham analgesic is applied onto a rubber hand. The effect was obtained by exploiting the rubber hand illusion, in which ownership is felt over a rubber arm that is unattached to the body. Under conditions of both synchronous and asynchronous visuo-tactile stimulation, a thermal pain stimulus was delivered on the real arm of twenty participants and seemingly also on the rubber arm, before and after applying a sham analgesic and a control cream only to the rubber arm. During synchronous visuo-tactile stimulation, pain was experienced on the rubber arm, and the application of the sham analgesic to the rubber arm significantly decreased the severity of reported pain. This demonstrates that experience of the body can modulate expectations and the induction of placebo analgesia.

In complex materials various interactions have important roles in determining electronic properties. Angle-resolved photoelectron spectroscopy (ARPES) is used to study these processes by resolving the complex single-particle self-energy and quantifying how quantum interactions modify bare electronic states. However, ambiguities in the measurement of the real part of the self-energy and an intrinsic inability to disentangle various contributions to the imaginary part of the self-energy can leave the implications of such measurements open to debate. Here we employ a combined theoretical and experimental treatment of femtosecond time-resolved ARPES (tr-ARPES) show how population dynamics measured using tr-ARPES can be used to separate electron-boson interactions from electron-electron interactions. We demonstrate a quantitative analysis of a well-defined electron-boson interaction in the unoccupied spectrum of the cuprate Bi2Sr2CaCu2O8+x characterized by an excited population decay time that maps directly to a discrete component of the equilibrium self-energy not readily isolated by static ARPES experiments.

It is thought that improving water, sanitation, and hygiene (WASH) might reduce the transmission of schistosomes and soil-transmitted helminths, owing to their life cycles. However, few large-scale studies have yet assessed the real extent of associations between WASH and these parasites.
