Meta-analytic evidence for a robust and positive association between individuals' pro-environmental behaviors and their subjective wellbeing
While it is often suggested that individuals' pro-environmental behaviors may be linked with their subjective wellbeing, the strength and direction (e.g. positive or negative) of this relation is unclear. Because pro-environmental behaviors impact peoples' everyday lives, understanding this relation is critical for promoting long-term environmental solutions. Using a series of meta-analyses, we systematically reviewed the literature on the association between individuals' pro-environmental behaviors and their subjective wellbeing. We hypothesized that the relation between pro-environmental behavior and subjective wellbeing would be positive and strongest among types of behaviors (e.g. sustainable purchase decisions) and indicators of subjective wellbeing which more clearly reflect personal meaning (e.g. warm glow). We sourced studies via PsychINFO, PsychARTICLES, GreenFile, SocINDEX, Web of Science, and Scopus, as well as professional email lists, direct contact with authors who publish in this domain, data from the authorship team, and the European Social Survey (2016). We included studies with quantitative data on the relation between individuals' pro-environmental behavior and their subjective wellbeing, ultimately identifying 78 studies (73 published, 5 unpublished) for synthesis. Across multiple indicators of pro-environmental behaviors and subjective wellbeing, we found a significant, positive relation (overall r = .243), and this relation did not meaningfully differ across study characteristics (e.g. sample, design). As predicted, the relation was particularly strong for indicators of pro-environmental behavior and subjective wellbeing which clearly reflect meaning, such as sustainable purchase decisions (r = .291) and for warm glow (r = .408). We found a robust, positive relation between people's pro-environmental behaviors and subjective wellbeing, and initial evidence that this relation may be stronger the more clearly behaviors and indicators of subjective wellbeing reflect meaning. Our results indicate that program and policy-makers can seek opportunities to design 'win-win' sustainability programs which could positively impact both people and the environment.

Doctors during the COVID-19 pandemic: what are their duties and what is owed to them?
Doctors form an essential part of an effective response to the COVID-19 pandemic. We argue they have a duty to participate in pandemic response due to their special skills, but these skills vary between different doctors, and their duties are constrained by other competing rights. We conclude that while doctors should be encouraged to meet the demand for medical aid in the pandemic, those who make the sacrifices and increased efforts are owed reciprocal obligations in return. When reciprocal obligations are not met, doctors are further justified in opting out of specific tasks, as long as this is proportionate to the unmet obligation.

SEAS5: the new ECMWF seasonal forecast system
In this paper we describe SEAS5, ECMWF's fifth generation seasonal forecast system, which became operational in November 2017. Compared to its predecessor, System 4, SEAS5 is a substantially changed forecast system. It includes upgraded versions of the atmosphere and ocean models at higher resolutions, and adds a prognostic sea-ice model. Here, we describe the configuration of SEAS5 and summarise the most noticeable results from a set of diagnostics including biases, variability, teleconnections and forecast skill.An important improvement in SEAS5 is the reduction of the equatorial Pacific cold tongue bias, which is accompanied by a more realistic El Niño amplitude and an improvement in El Niño prediction skill over the central-west Pacific. Improvements in 2 m temperature skill are also clear over the tropical Pacific. Sea-surface temperature (SST) biases in the northern extratropics change due to increased ocean resolution, especially in regions associated with western boundary currents. The increased ocean resolution exposes a new problem in the northwest Atlantic, where SEAS5 fails to capture decadal variability of the North Atlantic subpolar gyre, resulting in a degradation of DJF 2 m temperature prediction skill in this region. The prognostic sea-ice model improves seasonal predictions of sea-ice cover, although some regions and seasons suffer from biases introduced by employing a fully dynamical model rather than the simple, empirical scheme used in System 4. There are also improvements in 2 m temperature skill in the vicinity of the Arctic sea-ice edge. Cold temperature biases in the troposphere improve, but increase at the tropopause. Biases in the extratropical jets are larger than in System 4: extratropical jets are too strong, and displaced northwards in JJA. In summary, development and added complexity since System 4 has ensured that SEAS5 is a state-of-the-art seasonal forecast system which continues to display a particular strength in the El Niño Southern Oscillation (ENSO) prediction.

The ethics of sequencing infectious disease pathogens for clinical and public health
Using genomic technology to rapidly sequence and analyse pathogens has the potential to deliver a robust, evidence-based approach to the challenge of infectious disease management. The successful implementation of such a response is going to require consideration of the associated ethical, legal and social issues.A genomics-informed response to infectious disease has great potential to improve individual patient treatment as well as public health. This Comment discusses the ethical, legal and social challenges that will need to be overcome if clinical pathogen genomics is to be implemented successfully.

Exploring the ethics of genetic prioritisation for COVID-19 vaccines
There is evidence to suggest that host genomic factors may account for disease response variability in COVID-19 infection. In this paper, we consider if and how host genomics should influence decisions about vaccine allocation. Three potential host genetic factors are explored: vulnerability to infection, resistance to infection, and increased infectivity. We argue for the prioritisation of the genetically vulnerable in vaccination schemes, and evaluate the potential for ethical de-prioritisation of individuals with genetic markers for resistance. Lastly, we discuss ethical prioritisation of individuals with genetic markers for increased infectivity (those more likely to spread COVID-19).

Rethinking the ethical principles of genomic medicine services
Clinical genome and exome sequencing is currently used in only a small fraction of patients, yet large scale genomic initiatives are becoming more embedded in clinical services. This paper examines the ethical principles that should guide regulatory processes regarding consent and data sharing in this context. We argue that a genomic dataset administered by the health system carries substantial societal benefits, and that the collective nature of this initiative means that at least those patients who benefit from genome sequencing have an ethical obligation to share their health information. This obligation is grounded in considerations of fairness. Furthermore, we argue that the use of genomic data for the advancement of medical knowledge should be permitted without explicit consent and that international and other bodies should be granted access to these data, provided certain conditions are satisfied.

Transcriptomic analysis of Sorghum bicolor responding to combined heat and drought stress
Background
Abiotic stresses which include drought and heat are amongst the main limiting factors for plant growth and crop productivity. In the field, these stress types are rarely presented individually and plants are often subjected to a combination of stress types.
Sorghum bicolor
is a cereal crop which is grown in arid and semi-arid regions and is particularly well adapted to the hot and dry conditions in which it originates and is now grown as a crop. In order to better understand the mechanisms underlying combined stress tolerance in this important crop, we have used microarrays to investigate the transcriptional response of
Sorghum
subjected to heat and drought stresses imposed both individually and in combination.
Results
Microarrays consisting of 28585 gene probes identified gene expression changes equating to ~4% and 18% of genes on the chip following drought and heat stresses respectively. In response to combined stress ~20% of probes were differentially expressed. Whilst many of these transcript changes were in common with those changed in response to heat or drought alone, the levels of 2043 specific transcripts (representing 7% of all gene probes) were found to
only
be changed following the combined stress treatment. Ontological analysis of these ‘unique’ transcripts identified a potential role for specific transcription factors including MYB78 and ATAF1, chaperones including unique heat shock proteins (HSPs) and metabolic pathways including polyamine biosynthesis in the
Sorghum
combined stress response.
Conclusions
These results show evidence for both cross-talk and specificity in the
Sorghum
response to combined heat and drought stress. It is clear that some aspects of the combined stress response are unique compared to those of individual stresses. A functional characterization of the genes and pathways identified here could lead to new targets for the enhancement of plant stress tolerance, which will be particularly important in the face of climate change and the increasing prevalence of these abiotic stress types.
