A Collective CRISPR-Cas12a Biosensing Platform for Effect-Based Screening of Pesticide Residues ↗
The simultaneous screening of multicomponent pesticide residues, rather than a single specific compound, remains a critical yet challenging frontier in safety surveillance, largely due to the inherent one-to-one recognition bottleneck in conventional aptamer- or antibody-based biosensors. Herein, we develop a collective CRISPR-Cas12a biosensing platform for effect-based screening of pesticide residues by integrating effect-based enzymatic recognition with PAM-independent CRISPR signal amplification. Rather than employing a dedicated aptamer or antibody for each pesticide, the proposed strategy…

Biomolecules under Pressure: Protein Phase Transitions from Folding to Misfolding, Aggregation, and Condensation ↗
Abstract High hydrostatic pressure provides a unique and sensitive perturbation to protein structure, enabling direct measurement of volume changes associated with folding, misfolding, and assembly. Because pressure perturbs noncovalent forces while preserving covalent integrity, it reveals conformational intermediates that often remain hidden from thermal or chemical denaturation. Over the past decade, advances in high-pressure NMR, fluorescence spectroscopy, time-resolved crystallography, and single-molecule spectroscopy have transformed pressure into a high-resolution probe of folding lands…

A conserved archaeal protein with evolutionary links to bacterial ribosome hibernation and eukaryotic energy sensing ↗
Ribosome hibernation helps cells survive stress by reversibly silencing translation and preserving ribosomal complexes. Although well characterized in bacteria and eukaryotes, archaeal hibernation remains poorly understood. Using cryoEM of archaeal lysates, we identified AHA (AMPKγ-HPF from Archaea), a broadly conserved ribosome-associated factor composed of two modules. AHA bound across ribosomal subunits, occluding the mRNA channel and tRNA binding sites, supporting its role in ribosome hibernation. ΔAHA cells displayed reduced viability, loss of ribosomal proteins in the stationary phase, a…

The uplift of the Qinghai-Tibetan Plateau reshaped genome architecture and diversification of Asian torrent catfishes ↗
Tectonic uplift and mountain building are major drivers of species diversification and adaptation, yet how they reshape genome architecture and promote evolutionary innovation remains poorly understood. Here, we generated multiple chromosome-level genomes for Asian torrent catfishes (Sisoridae) and performed phylogenomic and comparative genomic analyses. Our results support an Asian origin of Sisoridae and provide a refined phylogenetic topology for catfishes. Comparative analyses revealed extensive chromosomal rearrangements during sisorid evolution, indicating highly dynamic genome architect

A bifunctional RNase H protein supports DNA replication and transcription in nucleus-forming Chimalliviridae phages ↗
Jumbo bacteriophages of the Chimalliviridae family replicate their genomes within a proteinaceous phage nucleus that spatially segregates viral DNA replication and transcription from translation. While the phage nucleus protects viral DNA from host defenses, it also imposes unique constraints on genome replication and gene expression. Here we identify the phage-encoded protein Rhc (RNase H-clamp) as a central mediator of genome transactions within the phage nucleus. Using the Escherichia coli infecting bacteriophage Goslar, we show that Rhc functions as an essential component of a non-canonica

Genome-wide mapping of endogenous topoisomerase cleavage complexes reveals TOP1 at the interface of DNA topological regulation and genome instability ↗
Topoisomerase cleavage complexes (TOPcc) are covalent protein-DNA intermediates formed transiently during topoisomerase catalysis and constitute a major class of DNA-protein crosslinks in human cells, yet their endogenous genomic distributions remain difficult to resolve. Here, we developed protein-DNA adduct immunoprecipitation followed by sequencing (pDAIP-seq), a highly sensitive method for detecting endogenous TOPcc that enables their genome-wide profiling under normal physiological conditions without stabilization by topoisomerase poisons. Using pDAIP-seq, we found that camptothecin treat

Corallimorpharian genome supports the monophyly of Scleractinia and illuminates the cellular evolution of coral calcification ↗
The production of calcified skeletons by stony corals is the cornerstone of reef ecosystems and the persistence of marine biodiversity. Corallimorpharians, sometimes described as naked corals, resemble stony corals in many respects but lack hardened skeletons. However, whether they are stony corals that secondarily lost their skeletons has been a subject of much debate. Here, we present a chromosome-level genome of the corallimorpharian Ricordea yuma and show that macrosynteny and microsynteny analyses provide strong support for corallimorpharians as the sister group to stony corals. This phyl

X-Y divergence of house fly (Musca domestica) proto-sex chromosomes follows distinct evolutionary trajectories despite residing in the same genome ↗
Sex determination systems and sex chromosomes frequently differ between species. One cause of these differences is new sex determining genes that drive evolutionary turnover of sex chromosomes. At the earliest stages of this turnover, X and Y (or Z and W) chromosomes start out as nearly identical homologs, and they can diverge via chromosomal rearrangements (e.g., inversions) that suppress X-Y recombination. However, multiple examples from across animals and plants provide exceptions to this canonical model of sex chromosome evolution. For example, some X-Y pairs remain undifferentiated for lo

Epigenetic regulators partition the genome by evolutionary and developmental constraint ↗
Many epigenetic regulators play essential roles in animal development, but precisely how they function across different cell types without clear sequence preferences remains a foundational challenge. Here, we employed single-cell RNA sequencing to survey the mutant phenotypes of 30 essential regulatory pathways across over 450 gastrulation stage mouse embryo replicates, including essential factors associated with repressive chromatin states, RNA surveillance/processing, and other genomic roles. We then use this integrated manifold to partition mutant responses into a developmentally-resolved i

Cis-meQTL mapping reveals genetic architecture of DNA methylation in a giga-genome species ↗
Abstract Whether variation in plant DNA methylation is mostly under genetic control (and therefore heritable and accessible to selection) or driven by environmental cues remains unsolved, which has consequences for epigenetic breeding and for understanding heritable phenotypic plasticity. We addressed this question by running cis-methylation quantitative trait locus (cis-meQTL) mapping across all three methylation contexts (CpG, CHG, and CHH) in 602 Norway spruce ( Picea abies (L.) H. Karst.) seedlings, pairing exome capture sequencing and targeted enzymatic methylation sequencing across the s

How to assess evidence about Biotechnology
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
