A recent study demonstrated the existence of mutations that facilitate access to efficient evolutionary solutions. Here I discuss the implications of this finding and the potential to open a new chapter in the study of evolvability.

Climate extremes threaten the land carbon sink and it is important to understand their impact in a changing climate. A recent study provides new insights on reduced forest carbon uptake during the severe 2022 drought and heatwave across Europe.

The availability of maker resources such as 3D printers, makerspaces, and public repositories enable researchers to share information with research peers, educators, industry, and the general public. This broadens the impact of research and inspires its extension and application.

The commercialization of DNA tagging is a growing trend that demonstrates the increasing practicality of this novel approach. This interdisciplinary technology is based on the distinctive characteristics of DNA as a molecule that can remain stable in varying environmental conditions and store data following appropriate preparation. Moreover, newly developed technologies could simplify DNA synthesis and the encoding of data within DNA. The implementation of DNA tagging presents distinctive benefits in comparison to conventional labelling techniques, including universal product code (UPC) barcoding, radio-frequency identification (RFID), quick response (QR) codes, and Bluetooth technologies, by surmounting the limitations encountered by these systems. The discourse pertains to extant DNA-tagging mechanisms along with prospective implementations in a wide range of domains, including but not limited to art, the metaverse, forensics, wildlife monitoring, and the military. The potential of DNA labelling in various contexts underscores the importance of continued research and development in this rapidly evolving field.

Seismological advances are presented and summarized to study the Earth’s core.

We propose the use of the terms natural gene drive (NGD) and engineered gene drive (EGD) arguing against James et al.¹, who think both should be included within the term “gene drive”, based on their mechanistic similarities.

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.

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.

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.

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.
