Field-effect transistors based on semiconductor nanocrystals are promising candidates for low-cost, flexible electronics. This work demonstrates fabrication on flexible substrates and low-voltage operations of integrated circuits based on nanocrystal transistors, including amplifiers and ring oscillators.

DNA as a high density storage medium is receiving increasing attention, but long term physical storage is an unsolved problem. Here the authors show that up to 1 TB of data stored as dehydrated DNA spots on a glass cartridge can be retrieved in a spot of water using digital microfluidics with minimal data loss and contamination.

Factors controlling the transfer of microbes from the ocean to the atmosphere are unclear. Here, Michaud et al. study this process in an enclosed ocean-atmosphere facility, and show that the degree of aerosolization of bacteria and viruses is taxon-specific.

How ocean acidification will impact coastal biogenic habitats is unclear. This study predicts that indirect effects on habitat-forming organisms, combined with direct effects on biodiversity, will cause changes in structural complexity and extent of these habitats.

Inadequate processing characteristics and performance are major obstacles to the broader adoption of sustainable polymer materials. Here, the authors show that co-assembly of oligopeptide-based polymer end groups and a corresponding low molar mass additive leads to a hierarchical structure, resulting in materials with improved processability and mechanical properties.

The mechanisms underlying gut microbial metabolite (GMM) contribution towards alcohol-mediated cardiovascular disease (CVD) are unknown. Herein, the authors reveal that alcohol-induced microbial reorganization and resultant elevation in GMM phenylacetylglutamine, directly contributes to CVD.

Uroz et al. report that the distinct mechanical properties of brain vasculature versus parenchyma drive cancer cell migration through a talin-dependent mechanism, enabling vessel co-option and metastatic invasion in the brain.

Multifilament surgical sutures functionalized with a conductive polymer and incorporating pledgets with capacitive sensors operated via radiofrequency identification can be used to monitor physicochemical states of deep surgical sites.

Skeletal muscles are impressive as they can achieve reversible, macroscopic, anisotropic motion in soft materials. Here the authors show a bottom-up design of macroscopic hydrogel tubes containing supramolecular nanofibers that can undergo anisotropic actuation by thermal stimuli.

By utilizing spatially resolved fluorescence (-lifetime) measurements and high precision X-ray nanodiffraction, the authors correlate the influence of structural misalignment and fluorescence (-lifetime) properties of all-inorganic CsPbX₃ (X^– = Br^–, Cl^–) perovskite superlattices.

Openshaw and colleagues find myeloid inflammation and complement activation signatures in patients with long COVID who were previously hospitalized.

Structural characterization of the bifunctional enzyme linalool dehydratase isomerase and exploration of its substrate scope demonstrate its potential for catalyzing desirable transformations of various tertiary alcohols.

Grant Stewart, Andrew Jackson, Christopher Mathew, Fowzan Alkuraya and colleagues identify a novel replication fork protein, DONSON, which is important for maintaining genome stability. Mutations in DONSON cause microcephalic dwarfism and lead to stalled replication forks and DNA damage.

A range of plastic semiconductors have been developed that have the combination of physical and chemical properties required to enable printable electronic circuitry, but these are almost exclusively 'hole transporting' materials. If an electron-transporting equivalent could be found, it could be combined with the existing classes of materials to produce yet more powerful devices. This paper reports the development of a such a material: the electron-transporting plastic semiconductor exhibits unprecedented device performance, and is compatible with a broad range of printing and processing technologies.

A non-stick surface coating makes medical devices anti-thrombogenic and resistant to biofilm growth.

Algae hold great promise for biofuel and chemical production but their use as model systems is hampered by the absence of suitable genetic tools. Here Karas et al. present a nuclear episomal vector for diatoms that is maintained in the absence of antibiotics, and a plasmid delivery method via conjugation with E. coli.

Candida glabrata bloodstream infections are thought to be mostly caused by a single strain. Here, the authors describe genotypic and phenotypic diversity of Candida glabrata in ten individual blood cultures, and find diversity in drug susceptibility and virulence within patients.

Loss of muscle satellite cells during aging has been thought to contribute to sarcopenia, but experimentally induced depletion of these cells in adult mice does not result in this condition.

Macrocycles are well represented in natural product structures but have been challenging to access for inclusion in synthetic libraries. A new method uses ring expansion to convert fused small rings into macrolactones and macrolactams that occupy natural product–like chemical space.

The authors use morphometric and brain lesion data to identify a convergent brain network shared by psychiatric disorders.

Marine records indicate a greenhouse to icehouse climate transition at ~34 million years ago, but how the climate changed within continental interiors at this time is less well known. Here, the authors show an orbital climate response shift with aridification on the northeastern Tibetan Plateau during this time.

How telomere dysfunction is directly linked to inflammation in humans is currently unclear. Here the authors reveal that telomere dysfunction drives activation of the YAP1 transcription factor, up-regulating the pro inflammatory factor, pro-IL-18 thus revealing a link between telomere dysfunction and initiation of intestinal inflammation.

This Resource describes genetic tools for microbial eukaryotes, providing a roadmap for developing genetically tractable organisms.

Global warming drove ‘wet gets wetter and dry gets drier’ climate shifts in Asia ~5.3 million years ago with monsoon pacing by ~400,000 and ~ 100,000 year cycles. This could be a template for future Asian climate response to anthropogenic warming.

Zachary Lippman and colleagues report mutations in the tomato ortholog of CLV1 and a gene encoding a hydroxyproline O-arabinosyltransferase enzyme that modifies CLV3, both of which cause fasciated flowers and fruits owing to increased meristem size. They also find that a natural mutation in CLV3 was a major target of selection during tomato domestication.

Using newly derived genome sequences of 137 marine microbial isolates as well as previously obtained genome and metagenome data, this study presents a functional analysis of picoplankton residing in the ocean's surface layer.

Katherine Siminovitch and colleagues show that mice expressing the autoimmune disease–associated Ptpn22 coding variant show thymic and splenic enlargement and lymphocyte and dendritic cell hyperresponsiveness. They further show that the variant promotes degradation of the protein, suggesting that it enhances autoimmune disease risk through a loss-of-function mechanism.

DNA can be amplified and sequenced from a single cell, but unevenness of the sequence coverage complicates efforts to assemble a high-quality genome. Chitsaz et al. devise an algorithm to address this problem and apply it to assemble a genome draft of an uncultured single-cell marine organism from one lane of Illumina sequence data.
