The study of Prebiotic Chemistry, and the closely related study of Astrobiology, is ultimately the study of our own point(s) of origin. Aiming to answer the questions of how, when, and where did the building blocks of life—i.e. biologically relevant organic molecules—form? With the imminent analysis of samples successfully returned from the near-Earth asteroid Bennu, and continuing discoveries from the Ryugu asteroid samples, the answers to some of these questions may be in sight.

Progress in treatment for glioblastoma is hindered by the blood-brain barrier (BBB). In genetic mouse models recapitulating brain invasion and abnormal angiogenesis of human glioblastoma, Cai and colleagues demonstrate that optical modulation of the BBB with nanoparticles boosts intratumoural chemotherapy concentration, prolonging survival. We discuss prospects for clinical translation of exemplary innovative techniques.

WHO guidelines for classification of malaria elimination in a country require that the risk of human infection from zoonotic, as well as nonzoonotic, malaria parasites is negligible. In this Comment, the authors discuss the implications of this policy for countries, such as Malaysia, with no recent reported nonzoonotic cases but ongoing zoonotic transmission.

Rapid Arctic warming may increase erosion and stream channel formation, which alters the flux of sediments, carbon, and nutrients in these sensitive ecosystems. Yet, understanding landscape change is hampered by a lack of predictive tools applicable to permafrost settings.

The authors comment that maximizing product concentration is a more meaningful target for CO2 electrolyzers than maximizing single-pass conversion.

Adopting standardized and reliable methodologies to accurately measure particle removal efficiency when developing fibrous materials for controlling airborne contamination is crucial. Here, the authors recommend best practices for experimental assessments and reporting to ensure a reliable evaluation of new airborne particle filtration media and technologies.

Molecular chaperones establish essential protein-protein interaction networks. Modified versions of these assemblies are generally enriched in certain maladies. A study published in Nature Communications used epichaperomics to identify unique changes occurring in chaperone-formed protein networks during mitosis in cancer cells.

The current gap between computing algorithms and neuromorphic hardware to emulate brains is an outstanding bottleneck in developing neural computing technologies. Aimone and Parekh discuss the possibility of bridging this gap using theoretical computing frameworks from a neuroscience perspective.

The response of aquatic and terrestrial organisms to climate change can depend on biological sex. A key challenge is to unravel the interactive effects of sex and climate change at the individual and population levels and the cascading effects on communities. This new understanding is essential to improve climate adaptation and mitigation strategies.

One Health refers to the interconnectedness of the health of humans, animals, and the environment. It recognises that coordination across sectors is needed for effective prevention, detection, and management of infectious disease threats. Although the concept of One Health is not new, it has gained increased prominence following the COVID-19 pandemic, prompting national and international institutions to adopt One Health policies aimed at preventing disease spillover^1–4. At Nature Communications, we have launched a Collection and call for papers in recognition of the need for better scientific evidence to support One Health policy ambitions.

Urea, a crucial nitrogen fertilizer, plays a vital role in meeting global food demand. However, its current production method is energy-intensive and environmentally unfriendly. In this commentary article, the authors propose strategies to address and overcome these challenges.

Resveratrol (REV) is a natural polyphenol with anti-obesity effects. However, the mechanisms remain unclear due to its low bioavailability and the lack of defined membrane-bound or nuclear receptors. Pang and colleagues reported that REV intervention (REV-I) alters gut microbiota and bile acid profile, leading to the inhibition of farnesoid X receptor (FXR) and attenuation of scavenger receptor class B type 1 (SR-B1)-mediated chylomicron secretion. This highlights a therapeutic potential of targeting gut microbiome and intestinal SR-B1 for obesity and diabetes treatment.

Medicinal chemistry is a fast-evolving interdisciplinary research area which aims to improve human life by developing drugs to combat diseases. Nature Communications interviewed three scientists, Daniele Castagnolo (Associate Professor at University College London), Paramita Sarkar (postdoctoral researcher at University of Würzburg) and Dani Schulz (Director, Discovery Process Chemistry at Merck), about their careers and the past and future in medicinal chemistry research. We asked the researchers what medicinal chemistry means to them, and their opinions on the current relevance of the Rule of Five and new chemical modalities beyond the Rule of Five. We also discuss the differences between academic and industry research in medicinal chemistry and how Open Science can support collaborations for drug development.

Protein lysine methylation plays important biological roles but its experimental characterization is limited by the lack of suitable mimetics of methylated and unmethylated lysine among the natural amino acids. Here, we summarize the consequent challenges and discuss alternative approaches for biochemical and cellular lysine methylation studies.

Terrestrial freshwater environments are both affected by and contribute to climate change, with highly complex feedback mechanisms. We must look to the records these environments preserve of past periods of climactic upheaval to be able to prepare for an uncertain future.

A new study sheds light on the impact of bimetallic interfaces in nanomaterials for heat generation using single-particle thermometry. Moving from nanoparticle ensembles to single particles is key to developing consistent knowledge of material performance and nanoscale processes, but also involves assumptions and definitions that require careful consideration.

In an alpha-synuclein (α-syn) model of Parkinson’s disease (PD), Schonhoff and colleagues have shown that central nervous system (CNS)-associated macrophages (CAMs), but not microglia, potentially orchestrate CD4⁺ T cell recruitment and mediate an α-syn-induced inflammatory makeup.

Topological electronics is an emerging field aiming at exploiting the topological properties of matter in devices with extended functionalities. Recent experiments demonstrate a topological current divider, a key circuit element for this emerging technology.

Here, we provide a brief overview of the approaches and strategies underlying bacteria-based cancer immunotherapy (BCiT). We also describe and summarize research in the field of synthetic biology, which aims to regulate bacterial growth and gene expression for immunotherapeutic use. Finally, we discuss the current clinical status and limitations of BCiT.

Whole genome sequencing has enabled new insights into the genetic architecture of complex traits, especially through access to low-frequency and rare variation. This Comment highlights the key contributions from this technology and discusses considerations for its use and future perspectives.
