Perspectives

Synthetic biology engineering principles enable two-way communication between living and inanimate substrates. Here the authors consider the development of this bio-informational exchange and propose cyber-physical architectures and applications.

Ketamine is associated with rapid antidepressant effects and temporary dissociative experiences, and this review examines whether these dissociative symptoms are necessary for antidepressant efficacy. Although the current literature does not support this relationship, further work is needed to explore possible associations at the molecular, biomarker, and psychological levels.

A key security challenge with biosecurity threats is determining the responsible actor. In this Perspective, the authors review recent developments in using genetic sequence to assign a lab-of-origin and the potential protection it provides against misuse of synthetic biology.

Many fluid biomarker findings have had low reproducibility despite initially promising results. Here, the authors review possible sources for low reproducibility of studies on fluid biomarkers for neurodegenerative diseases and suggest guidelines for the biomarker community to agree on and implement.

Maria Antfolk and Kim Jensen discuss how to model intestinal epithelial cell function in the dish and how various physiologically important environmental conditions, for example, extracellular matrix, pressure and flow, can be modelled and how this is applicable to clinical work.

Advances in our ability to manipulate genetics leads to deeper understanding of biological systems. In this Perspective, the authors argue that synthetic genomics facilitates complex modifications that open up new areas of research.

The IMEx consortium provides one of the largest resources of curated, experimentally verified molecular interaction data. Here, the authors review how IMEx evolved into a fundamental resource for life scientists and describe how IMEx data can support biomedical research.

Marine aquaculture is widely proposed as compatible with ocean sustainability, biodiversity conservation, and human nutrition goals. In this Perspective, Belton and colleagues dispute the empirical validity of such claims and contend that the potential of marine aquaculture has been much exaggerated.

Marine microbial activities fuel biogeochemical cycles that impact the climate, but global models do not account for the myriad physiological processes that microbes perform. Here the authors argue for a model framework that reinterprets the ocean as physics coupled to biologically-driven redox chemistry.

Discovering a sustainable route to ammonia as a fertiliser and as an energy carrier is critically important, but many recent reports on the electrochemical nitrogen reduction are false positives. Here the authors uncover the emerging experimental traps and detail protocols to reliably avoid them.

The accurate representation of data is essential in science communication, however, colour maps that visually distort data through uneven colour gradients or are unreadable to those with colour vision deficiency remain prevalent. Here, the authors present a simple guide for the scientific use of colour and highlight ways for the scientific community to identify and prevent the misuse of colour in science.

Oncogenic signalling has been historically associated with sustained cancer cell-intrinsic proliferation, however its role in promoting tumour immunoresistance has also become evident. Here, Hamarsheh and colleagues review and discuss the preclinical work on the immune modulatory effects of oncogenic KRAS and the potential clinical application.

Reducing soil degradation and improving soil management could make an important contribute to climate change mitigation. Here the authors discuss opportunities and challenges towards implementing a global climate mitigation strategy focused on carbon sequestration in agricultural soils, and propose a framework for guiding region- and soil-specific management options.

Plastic pollution is recognized as a global threat, but policy hurdles and a lack of effective plastic substitutes contribute to the problem. In this Perspective, the authors argue that an effective and sustainable path forward must rely on key restrictions and regulations optimized for impact and efficacy.

Non-model bacteria offer unique and versatile metabolisms for synthetic biology. In this Perspective, the authors explore the limited availability of well-characterised biological parts in these species and argue that bacteriophages represent a diverse trove of orthogonal parts.

The Human Proteome Project (HPP) was launched in 2010 to enhance accurate annotation of the genome-encoded proteome. Ten years later, the HPP releases its first blueprint of the human proteome, annotating 90% of all known proteins at high-stringency and discussing the implications of proteomics for precision medicine.

Biofortification is an effective means to reduce micronutrient malnutrition. Here, the authors review recent advances in biofortification and propose stacking multiple micronutrient traits into high-yielding varieties through the combination of conventional breeding and genetic engineering approaches.

The social intelligence hypothesis predicts that social organisms tend to be more intelligent because within-group interactions drive cognitive evolution. Here, authors propose that conspecific outsiders can be just as important in selecting for sophisticated cognitive adaptations.

In this Perspective, the authors review the different applications for mobile phone data to support COVID-19 pandemic response, the relevance of these applications for infectious disease transmission and control, and potential sources and implications of selection bias in mobile phone data.
