Plants, fungi and oomycetes: a 400-million year affair that shapes the biosphere

Abstract: 10 New Phytologist Workshop on the ‘Origin and evolution of plants and their interactions with fungi’, London, UK, September 2014 In a rare gathering, genomics met palaeontology at the 10 New Phytologist Workshop on the ‘Origin and evolution of plants and their interactions with fungi’. An eclectic group of 17 expertsmet at The Natural History Museum (London, UK) on 9–10 September 2014 to discuss the latest findings on plant interactions with fungi (Eumycota) and oomycetes (Oomycota = Peronosporomycota), with topics ranging from the fossil record and comparative genomics to symbiosis and phytopathology. The discussions were largely disseminated via socialmedia (Box 1).Highly diverse plant– fungal interactions have formed the backbone of land ecosystems and biogeochemical cycles since the Palaeozoic (see Fig. 1 for geological timeframe). As summarized by Christine StrulluDerrien andPaulKenrick (TheNaturalHistoryMuseum,London, UK) the first land plants arose c. 470 million years (Myr) ago (Kenrick et al., 2012; Edwards et al., 2014), at which time fungi and oomycetes had already colonized terrestrial ecosystems. Following their terrestrialization, these microbes began to abound within plant fossils (Taylor et al., 2014, and references therein). Ultimately, biological interactions sculpted the genomes of plants, fungi and oomycetes (e.g. Schmidt & Panstruga, 2011; Kohler et al., 2015). Here we illustrate the picture that has emerged from the discussions at the 10 New Phytologist Workshop, and point to some pending questions.

Chronic Pain and PTSD: Evolving Views on Their Comorbidity

Abstract: Purpose This paper presents a literature review of post-traumatic stress disorder (PTSD) and its link to chronic pain. Design and Methods Twenty-four papers are reviewed (included research and reviews), with the goal of improving and updating our understanding on this issue and its theoretical and clinical repercussions. Findings The tight interdependence of symptoms that can be observed in both PTSD and chronic pain syndromes lends support to the idea that these disorders both constitute a reactive disorder. Practice Implications Various forms of therapy and treatment focus on PTSD, but chronic pain symptoms must also be assessed.

Teacher satisfaction with school and psychological well-being affects their readiness to help children with mental health problems

Abstract: Objective: In support of a whole-school approach to mental health promotion, this study was conducted to find out whether and how significantly teachers’ satisfaction with school and their subjective psychological well-being are related to the belief that they can help pupils with mental health problems.

Flexible Regenerated Cellulose/Boron Nitride Nanosheet High-Temperature Dielectric Nanocomposite Films with High Energy Density and Breakdown Strength

Abstract: Traditional dielectric polymers are nonbiodegradable and nonrenewable petroleum-derived synthetic ones. Here, we report on flexible and 2D nanolayer-structured nanocomposite dielectric films which ...

Flux rectification in the quantum X X Z chain

Abstract: Thermal rectification is the phenomenon by which the flux of heat depends on the direction of the flow. It has attracted much interest in recent years due to the possibility of devising thermal diodes. In this paper, we consider the rectification phenomenon in the quantum XXZ chain subject to an inhomogeneous field. The chain is driven out of equilibrium by the contact at its boundaries with two different reservoirs, leading to a constant flow of magnetization from one bath to the other. The nonunitary dynamics of this system, which is modeled by a Lindblad master equation, is treated exactly for small sizes and numerically for larger ones. The functional dependence of the rectification coefficient on the model parameters (anisotropy, field amplitude, and out of equilibrium driving strength) is investigated in full detail. Close to the XX point and at small inhomogeneity and low driving, we have found an explicit expression for the rectification coefficient that is valid at all system sizes. In particular, it shows that the phenomenon of rectification persists even in the thermodynamic limit. Finally, we prove that in the case of the XX chain, there is no rectification.
