Consistent negative response of US crops to high temperatures in observations and crop models

High temperatures are detrimental to crop yields and could lead to global warming-driven reductions in agricultural productivity. To assess future threats, the majority of studies used process-based crop models, but their ability to represent effects of high temperature has been questioned. Here we show that an ensemble of nine crop models reproduces the observed average temperature responses of U

A Lagrangian model of air-mass photochemistry and mixing using a trajectory ensemble : The Cambridge Tropospheric Trajectory model of Chemistry And Transport (CiTTyCAT) version 4.2

A Lagrangian model of photochemistry and mixing is described (CiTTyCAT,stemming from the Cambridge Tropospheric Trajectory model of Chemistry AndTransport), which is suitable for transport and chemistry studies throughoutthe troposphere. Over the last five years, the model has been developed inparallel at several different institutions and here those developments havebeen incorporated into one "co

The influence of small-scale variations in isoprene concentrations on atmospheric chemistry over a tropical rainforest

Biogenic volatile organic compounds (BVOCs) such as isoprene constitute a large proportion of the global atmospheric oxidant sink. Their reactions in the atmosphere contribute to processes such as ozone production and secondary organic aerosol formation. However, over the tropical rainforest, where 50 % of the global emissions of BVOCs are believed to occur, atmospheric chemistry models have been

Retrospective study of maternal and neonatal outcomes after induction compared to spontaneous start of labour in women with one previous birth in uncomplicated pregnancies ≥ 41+3

To study the association between induction and outcome among two-parous women in uncomplicated pregnancies ≥ 41+3, stratified by first labour delivery mode and conditions present at first delivery. The Swedish Medical Birth Register was used to identify 58,964 uncomplicated singleton pregnancies among women with one previous birth between 1998 and 2014. Women with any registered pregnancy complica

Towards unravelling Wolbachia global exchange : a contribution from the Bicyclus and Mylothris butterflies in the Afrotropics

Background: Phylogenetically closely related strains of maternally inherited endosymbiotic bacteria are often found in phylogenetically divergent, and geographically distant insect host species. The interspecies transfer of the symbiont Wolbachia has been thought to have occurred repeatedly, facilitating its observed global pandemic. Few ecological interactions have been proposed as potential rout

Preference for supernormal stimuli tends to override initially learned associations for conspicuous prey traits : implications from a laboratory study

How predators select on conspicuous prey traits is not well understood. We used a laboratory setup to investigate the role of learning in predator choice of conspicuous visual traits. We used a generalist predator, the great tit, and coloured wings of males of two species of damselflies as prey. Wing pigmentation differs between the species in colour (green vs. blue) and size (large vs. small). Wi

Navigating in a Misty Landscape–Perceptions of Supporting a Relative Residing in Supported Housing for People with a Psychiatric Disability

The aim was to explore informal carers’ perceptions of supporting the everyday life of a relative who has a psychiatric disability and resides in supported housing (SH). A qualitative study based on interviews with 12 informal carers was performed, and the data was analyzed with qualitative content analysis. The theme “Navigating in a misty landscape when striving to support a relative with a psyc

Cuban socialism at 60 : Old aspirations and new realities

Few revolutions have had such an impact in modern times as the Cuban Revolution in 1959. Numerous publications (books, articles, and dissertations) have been written about it. Opinions about it have diverged. The revolution has been an inspiration for many, contested and even detested by others. In 1961, the Cuban Revolution took a radical turn when Fidel Castro declared that the revolution was so

Differences in self-perceived general health, pain, and depression 1 to 5 years post-stroke related to work status at 1 year

Stroke is one of the most common diseases and has several potential consequences, such as psychological problems and pain. Return to work (RTW) after stroke in working-age individuals is incomplete. The present study aimed to investigate differences in self-perceived general health, pain, and depression between 1 and 5 years post-stroke related to RTW status. The study was nationwide, registry-bas

Fine-tuning the metabolic rewiring and adaptation of translational machinery during an epithelial-mesenchymal transition in breast cancer cells

Abstract: Background: During breast cancer progression, the epithelial to mesenchymal transition has been associated with metastasis and endocrine therapy resistance; however, the underlying mechanisms remain elusive. To gain insight into this process, we studied the transition undergone by MCF7-derived cells, which is driven by the constitutive nuclear expression of a MKL1 variant devoid of the a

Prediction of neurological outcome after cardiac arrest and targeted temperature management

Background: Prediction of neurological outcome in unconscious patients after cardiac arrest (CA) forms the basis for decisions on further level-of-care based on results from clinical neurological examinations, neuroimaging (CT or MRI), neurophysiology (EEG or SSEP) and blood biomarkers of brain injury. Methods must be highly specific to avoid misclassifying patients with possibilities of a good ou
