While over 99% of coastal arctic rivers drain small catchments, future projections of land-ocean fluxes are based on data from large rivers. We encourage inclusion of and increased focus on smaller catchments to support representative assessments of arctic ecosystem change.
In this Comment, the authors discuss the current status, the challenges, and potential technological impact of exciton transport in transition metal dichalcogenide (TMD) monolayers, lateral and vertical heterostructures as well as moiré excitons in twisted TMD heterostacks.
The Tara Pacific program and expedition focused on coral reefs across the Pacific Ocean and used a coordinated sampling effort to address questions at multiple scales using a common suite of samples. Here, we highlight some of the Tara Pacific achievements, discussing the benefits of long-duration sea expeditions for investigating a wide array of research questions within a selected ecosystem.
The samples returned from near-Earth asteroid (162173) Ryugu provide a pristine record of the 4.6 billion years since the birth of the Solar System. The Hayabusa2 initial analysis team has integrated a range of analytical techniques to investigate Ryugu’s organic chemistry. Here, we highlight their latest findings, the potential questions which may be answered, and provide an overview of new prospects in the decade to come.
On September 26th 2022, LICIACube monitored Double Asteroid Redirection Test (DART) mission impact on asteroid Dimorphos, which is the smaller component of a binary asteroid system. These close observations revealed the impact ejecta features of the first planetary defence test with a kinetic impactor.
Identifying topological defects in disordered materials has a profound effect on predicting when and where the material will break. Matteo Baggioli comments a recent publication in Nature Communications, which confirms the existence of defects in glasses and their crucial role for plasticity.
Early detection of immunotherapy-induced tumor response is of major benefit for patients but can be complicated by therapy-induced pseudoprogression. A consensus guideline-iRECIST- was developed as a modification of Response Evaluation Criteria in Solid Tumours (RECIST version 1.1). Here we describe which next steps are required to test its validity and how novel approaches for response criteria might be developed and included.
Issues with data reuse have been recognized in synthetic biology and the broader scientific community. Policies and standards fall short as machine reasoning is not emphasised and enforcement is lacking. We discuss the progress, remaining challenges, and possible solutions.
Progress to reduce plastic pollution has been painfully slow and the consequent damage to the natural environment and to human health is likely to increase further. This has been because the views and ways of working of four distinct stakeholder communities are not sufficiently well integrated. (1) Scientists, (2) industry, (3) society at large and (4) those making policy and legislation must in future find ways to work together.
This Comment discusses the complexity of how ocean acidification and phosphate limitation affect phytoplankton physiologies, as well as what future research is needed to address remaining crucial questions.
Genetic modification is a cornerstone of modern plant biology research and has the potential to transform agriculture. To have the greatest impact, it is essential that the characteristics of new plant genotypes and the methodology used to produce them are accurately reported in the scientific literature. Nature Communications is therefore asking for specific methodological details regarding the production of novel plant genotypes to improve transparency and reporting in plant biology.
This comment explores ethical aspects in developing and testing minimal-risk devices, such as wearables and biomedical sensors. Authors outline the process of independent review, emphasizing the different levels of review depending on the research design and risk level. They also share examples of practical scenarios, highlighting key ethical considerations.
A long-standing issue in astrobiology is whether planets orbiting the most abundant type of stars, M-dwarfs, can support liquid water and eventually life. A new study shows that subglacial melting may provide an answer, significantly extending the habitability region, in particular around M-dwarf stars, which are also the most promising for biosignature detection with the present and near-future technology.
Despite worldwide prevalence, post-agricultural landscapes remain one of the least constrained human-induced land carbon sinks. To appraise their role in rebuilding the planet’s natural carbon stocks through ecosystem restoration, we need to better understand their spatial and temporal legacies.
Cell division critically requires amplification of microtubules (MTs) in the bipolar mitotic spindle. This relies on the filamentous augmin complex that enables MT branching. Studies by Gabel et al., Zupa et al. and Travis et al. describe consistent integrated atomic models of the extraordinarily flexible augmin complex. Their work prompts the question: what is this flexibility really needed for?
The early Hadean eon (>4Ga) may have had a periodically ice-covered global ocean and limited subaerial landmass, and this could have resulted in infrequent lightning occurrence. This infrequency of lightning may have limited the synthesis of prebiotic compounds necessary for life’s origins. Here I present a hypothesis that lightning associated with volcanic island eruptions created focal points for the generation of prebiotic ingredients and ultimately the origin of life.
The type three secretion system (T3SS) is a membrane-anchored nano-machine utilized by many pathogenic bacteria to inject effector proteins and thus take control of host cells. In a recent article, Kaval et al. reveal a striking colocalization of a T3SS-encoding locus, its transcriptional activators, protein products, and the complete structure at the cell membrane, which they claim provides evidence for a mechanism known as ‘transertion’.
Detecting and quantifying the causal relations of ecosystem functioning is a challenging endeavor. This Comment discusses a global study on grasslands and illustrates how reasoning about underlying assumptions is key to modern causal inference approaches in ecology.
Lack of information on authors’ contribution to specific aspects of a study hampers reproducibility and replicability. Here, the authors propose a new, easily implemented reporting system to clarify contributor roles in the Methods section of an article.
