CXCL4 is an inflammatory chemokine signaling through CXCR3 receptor. Here the authors show a CXCR3-independent function of CXCL4: it forms liquid crystals with DNA, potentiating mammalian and bacterial DNA recognition by TLR9, thereby amplifying interferon-a production in systemic sclerosis.

A diet–microorganism pathway involving conjugated linoleic acid, interleukin-18, intraepithelial lymphocytes and the transcription factor hepatocyte nuclear factor  4γ modulates the host mucosal immune system.

Microbes play key roles in wastewater treatment.

A microfluidics approach that links short sequence reads enables haplotype construction and complex variation identification from tiny amounts of input DNA.

In this new study the Authors demonstrated that the IGFBP3/TMEM219 pathway is a physiological regulator of pancreatic beta cell homeostasis and it is dysregulated in diabetes. IGFBP3/TMEM219 targeting may therefore serve as a therapeutic option in diabetes.

D’Adda di Fagagna and colleagues observe that, after genotoxic treatment of cells and mice, unrepaired DNA-damage foci and DNA-damage signalling persist at telomeres. They show that introducing the telomeric protein TRF2 near a double-strand break elsewhere on the chromosomes prevents repair. Unrepaired foci are also observed at telomeres of ageing animals, suggesting a role for TRF2 in senescence establishment.

Volatile aldehydes can be enriched in esophageal adenocarcinoma patients’ breath. Here, the authors reveal corresponding metabolic changes in EAC tumours, which may be caused by impaired detoxification of endogenous metabolites.

Agricultural soil C dynamics under climate change are difficult to predict. Here, the authors report that experimental warming increases soil organic C stocks in conservation agriculture but not in conventional agriculture, which appears driven by soil microbial responses to no tillage and C inputs from the crops.

The Late Cretaceous experienced significant cooling, yet a lack of low-latitude records mean the regional extent of this cooling is poorly constrained. Linnert et al. present a TEX₈₆sea surface temperature record from a palaeolatitude of ~35 °N and show that Late Cretaceous cooling was global in nature.

Cupedo and colleagues show that neutrophils promote a tumor-supportive microenvironment via a self-amplifying interaction between neutrophils and bone marrow stromal cells. This scenario creates a promyeloma niche that is difficult to treat despite targeted therapies directed at the myeloma cells.

Cells exert tight control over the size of their compartments in order to regulate their function. Here, nuclear fluorescence exclusion microscopy is able to measure the nuclear and cytoplasmic volumes of live cells in a high-throughput way.

E217 is a Myoviridae used in an experimental phage cocktail to eradicate Pseudomonas aeruginosa. Here, the authors utilize cryo-EM and functional analysis to delineate E217 structural proteins, tail dynamics, and mechanisms of host recognition.

A second hit to Brca1 in heterozygous mice leads to accelerated tumor development compared to wild-type mice in which both alleles are simultaneously deleted. This is because of an epigenetic state associated with Brca1 haploinsufficiency that impacts AP-1 and Wnt10a.

Here, the authors report that exhausted HCV-specific CD8+ T cells are marked by upregulation of p53 signaling already detectable in an early phase of chronic HCV infection and by a later development of a repressive chromatin state, and show that chemical targeting of these pathways improves CD8+ T cell metabolism and antiviral function.

Laser spectroscopy measurements of the fermium isotopic chain show a smooth trend in the nuclear size of heavy actinide elements, and diminishing shell effects on the size evolution compared with lighter nuclei.

ALT cells use an alternative lengthening mechanism of telomeres and bear telomeric DNA damage with increased levels of damage-induced long non-coding RNA. Here the AUs show that antisense oligonucleotides (ASO) targeting such RNAs can induce ALT cancer cells selective cell death.

Although ageing is the most important risk factor for chronic ailments, effective interventions remain rare. Here, the authors identify the flavonoid 4,4’-dimethoxychalcone and demonstrate that it extends lifespan and promotes health in multiple organisms by inducing autophagy.

Response to immune checkpoint inhibitors (ICIs) in patients with non-small cell lung cancer (NSCLC) remains suboptimal, even for tumors with elevated tumor mutational burden. Here the authors generate a model of NSCLC with enhanced mutational load, showing that, while still resistant to ICIs, hypermutated tumors become sensitive to dendritic cell-targeted therapy.

Bacterial cell growth and division require the coordinated action of enzymes that synthesize and degrade cell wall polymers. Here, the authors identify enzymes that cleave the D-arabinan core of arabinogalactan, an unusual component of the cell wall of Mycobacterium tuberculosis and other mycobacteria.

The X-ray source M33 X-7 hosts a rapidly spinning, 15.65M_¤ black hole orbiting an underluminous, 70M_¤ main-sequence companion in a slightly eccentric 3.45-day orbit. Hitherto, there has been no satisfactory explanation for the observed properties. These authors report simulations of evolutionary tracks which reveal that if M33 X-7 started as a primary body of 85M_¤–99M_¤ and a secondary body of 28M_¤–32M_¤, in a 2.8–3.1-day orbit, its properties can be consistently explained.
