Metabolic "dark matter" describes currently unknown metabolic processes, which form a blind spot in our general understanding of metabolism and slow down the development of biosynthetic cell factories and naturally derived pharmaceuticals. Mapping the dark matter of metabolism remains an open challenge that can be addressed globally and systematically by existing computational solutions. In this work, we use 489 generalized enzymatic reaction rules to map both known and unknown metabolic processes around a biochemical database of 1.5 million biological compounds. We predict over 5 million reactions and integrate nearly 2 million naturally and synthetically-derived compounds into the global network of biochemical knowledge, named ATLASx. ATLASx is available to researchers as a powerful online platform that supports the prediction and analysis of biochemical pathways and evaluates the biochemical vicinity of molecule classes (https://lcsb-databases.epfl.ch/Atlas2).

The technological innovation systems (TIS) framework is one of the dominant perspectives in transitions studies to analyze success conditions and system failures of newly emerging technologies and industries. So far, TIS studies mostly adopted a rather harmonious view on the values of actors and by this were unable to address competition, conflicts and, in particular, battles over diverging directionalities within the system. To empirically assess this potential “harmony fallacy”, we identify values as part of underlying institutional logics of major organizations in the field of modular water technologies in Switzerland by means of 26 expert interviews. We show how logics may condition collaboration patterns and technological preferences. This analysis inspires key conceptual tasks of innovation system analysis, like the identification of system failures, the setting of appropriate system boundaries and the formulation of better policy recommendations.

The journal Environmental Innovation and Societal Transitions (EIST) recently celebrated its tenth anniversary. Its development represents a great success, contributing substantially to the consolidation and maturation of the research field of sustainability transitions. However, being content with past successes will not be sufficient for tackling emerging challenges. In this perspective paper, we take stock of recent dynamics in the field by analyzing the evolving knowledge structure of the papers published in the journal. Based on these insights, we share the editorial priorities of the new editorial team and elaborate how we want to position the journal in the rapidly changing landscape of academic publishing. This is in the hope to align expectations with future authors and readers and to serve our quickly growing research field even better as it increasingly gains academic recognition and policy relevance.

Complex environmental and public policy decisions profit from structured procedures such as multi-criteria decision analysis (MCDA). To support such decisions, the new open source application ValueDecisions provides advanced analysis and visualization with no programming expected from users. Based on multi-attribute value theory (MAVT), it offers analysis for decisions with conflicting and interacting objectives, multiple stakeholders, and uncertain consequences of options. Programmed in R, the shiny web framework makes it accessible via a graphical user interface in the browser. We exemplify using ValueDecisions for a wastewater infrastructure planning case in the Paris region. We surveyed preferences of 655 citizens and conducted sensitivity analysis of preference parameters. The best management options were robust across a range of preference profiles and assumptions. To evaluate the app, we developed a novel usability test based on the ISO standard for software quality and surveyed students using ValueDecisions for case studies.
