In recent years, omics sciences have experienced rapid global growth, and Brazil, with its increasing scientific relevance, has actively participated in this process. Among the various definitions of omics sciences, the concept of integrated approaches aiming the comprehensive and systematic characterization of different biomolecules in biological systems is particularly familiar from a chemical perspective. Understanding chemical composition enables a broad comprehension of the organization, dynamics, and interactions among molecular components, allowing the investigation of complex biological processes, environmental responses, and regulatory mechanisms at multiple levels, from cells to ecosystems.

Scientific journals are foundational to the modern research ecosystem. They are the primary formal medium by which empirical results, theoretical developments, and methodological advances are communicated and validated. Their relevance to innovation arises from their core functions: codifying and communicating new knowledge, facilitating systematic dissemination of original research. The peer review system is designed to ensure that claims are supported by evidence, that methods are described in sufficient detail to allow replication, and that conclusions flow logically from data, enabling other researchers to build upon validated findings rather than merely speculative claims. Chemical journals maintain high standards for experimental description (e.g., detailed synthetic procedures, analytical data, proof of structure), serving as gatekeepers and quality filters.

As a fallible process since its origins, peer review continues to be a widely debated aspect of modern science. Most scientists, if not all, are familiar with the infamous “reviewer #2” (R#2), synonymous with the “bad” reviewer, notorious for excessive or nonsensical demands. The internet is filled with jokes and sketches about R#2, and most readers have likely encountered a few. While it is not always R#2, this reviewer is often blamed and, interestingly, commonly perceived as male. Even the most diligent and competent reviewers have likely been labeled as R#2 at some point.
