  • Micro Capture-C applied to single alleles links noncoding variants to target genes and allelic expression. Across 405 immune-disease regulatory elements in CD4+ T cells it found a risk variant that creates a new CTCF motif, blocking super-enhancer contact with SESN3, which senses tryptophan to regulate mTOR.

  • Screening 94 dietary components in synthetic gut communities showed Segatella copri outcompetes Bacteroidaceae on polysaccharides such as arabinan only when Enterobacteriaceae are present. Global metagenomes show the same pairing in non-industrialized microbiomes.

  • H3K4 methylation primes MYC for amplification by the demethylase KDM4C, while SETD2 restrains it. Losing SETD2 drives stepwise copy gains, and blocking apoptosis or losing TP53 lets them progress to extrachromosomal DNA; KDM4C inhibition suppresses amplification.

  • uRARE-seq, a urine cell-free RNA assay tested on 683 samples, detected localized bladder cancer with 95% sensitivity at 90% specificity, outperformed urine tumour DNA, and distinguished complete responses after surgery from those after BCG.

  • In Arabidopsis, DNA methylation can either block or promote Polycomb H3K27me3 at transposable elements depending on the locus; at one newly inserted TE, H3K27me3 needs the de novo methyltransferase DRM2.

  • Membranes matching the lipid make-up of the minimal cell JCVI-syn3A rely on cholesterol and sphingomyelin to stay ordered but fluid, shown with cryo-EM, monolayer, permeability and simulation experiments.

  • High salt concentration in the renal medulla drives maturation of kidney collecting ducts through NFAT5. Used with hormones, it gave mature human collecting-duct organoids that model nephrogenic diabetes insipidus.

  • Matching a foam-cell gene regulatory network to drug expression profiles identified auranofin, a gold salt for rheumatoid arthritis, which reduced atherosclerosis in mice and rabbits and was associated with lower cardiovascular risk in a retrospective patient analysis.

Statistics and methods_

  • DeCoRE uses nanopore direct RNA sequencing to separate alternative RNA structures on individual transcripts at single-nucleotide resolution, recovering known riboswitch conformations.

  • A two-step model predicts liquid chromatography retention order first, then maps it to retention time, giving retention-time prediction on a new system without training data from that system.

Adjacent biology_

  • Across 4,351 timing estimates for 549 bird species, migration advanced 13.86 days from 1970 to 2019. Earlier spring migration helped populations; earlier autumn migration was associated with declines.

Agriculture and breeding_

  • A meta-analysis plus greenhouse and decade-long field trials found that maize cultivars with high or low nitrogen-use efficiency differ in how their arbuscular mycorrhizal fungi respond to nitrogen fertiliser.
