The Krüppel-like factors Klf4 and Klf5 have wide roles in cell biology including the regulation of pluripotency. In this study, Aksoy et al. demonstrate that Klf4 preferentially blocks the expression of endodermal markers in embryonic stem cells, whereas Klf5 negatively regulates mesodermal factors.

UDP-glucuronic acid is a component of the extracellular matrix. Here, the authors report biallelic variants in the gene encoding UDP-Glucose 6-Dehydrogenase (UGDH) in individuals affected by developmental epileptic encephalopathies that impair UGDH stability, oligomerization, or enzymatic activity in vitro.

Safety and efficacy remain important challenges for non-antiretroviral-based microbicides. Here, Derby et al. show that a Griffithsin-Carrageenan fast dissolving vaginal insert provides on-demand protection against SHIV infections in macaques, paving the way for the development of pre-exposure prophylaxis on-demand products.

The Large Hadron Collider beauty collaboration reports a test of lepton flavour universality in decays of bottom mesons into strange mesons and a charged lepton pair, finding evidence of a violation of this principle postulated in the standard model.

Antiviral nanoparticle-formulated mimics of heparan sulfate proteoglycans were developed and shown to permit strong viral association as well as inhibition of a range of viruses on in vitro and in vivo models of infection.

A Middle–Late Triassic tetrapod assemblage from South America reveals a series of faunal turnovers prior to the rise of dinosaurs in the region.

Chronic myeloid leukaemia is characterized by the genetic translocation t(9;22) encoding for BCR-ABL oncogene; however, the molecular mechanisms of disease progression are poorly understood. Here Amabile et al. show that aberrant methylation is promoted by BCR-ABL, driving the evolution of the disease.

This is an issue edsumm for ng1939. Identification of the Palaeocene/Eocene thermal maximum in a marine sedimentary sequence. It shows that sea surface temperatures near the North Pole increased from roughly 18 degrees Celsius to over 23 degrees Celsius — such warm values imply the absence of ice and thus exclude the influence of ice-albedo feedbacks on this Arctic warming.

A genome-wide association study including 22,389 cases of multiple sclerosis finds an association with disease progression at the DYSF–ZNF638 and DNM3–PIGC loci and identifies a potential of higher educational attainment in slowing disease progression.

Ten years after the discovery of the Higgs boson, the ATLAS  experiment at CERN probes its kinematic properties with a significantly larger dataset from 2015–2018 and provides further insights on its interaction with other known particles.

The existence and properties of tetraquark states with two heavy quarks and two light antiquarks have been widely debated. Here, the authors use a unitarized model to study the properties of an exotic narrow state compatible with a doubly charmed tetraquark.

The LHCb collaboration reports an improved measurement of the oscillation frequency of mesons consisting of a bottom quark and strange quark, which is then combined with previous results.

Power exhaust is one of the biggest challenges stopping fusion energy. This article shows experimental evidence for strategically shaping the power exhaust region as a solution to this challenge, utilising physics understanding to strike a balance between engineering complexity and power exhaust benefits, consistent with reduced models and simulations.

Genome-wide analysis of self-reported dyslexia identifies 42 associated loci, including 27 not previously associated with cognitive traits. Dyslexia shows genetic correlation with ambidexterity but not neuroanatomical measures of language-related circuitry.

Wave mixing in optical resonators suffers from strong bandwidth constraints, hindering practical implementation. Morichettiet al. report travelling-wave four-wavemixing in coupled ring resonators, which combines the efficiency enhancement of resonant propagation with a wide-band conversion process.

Spin orbit coupling (SOC) is a feature crucial to many interesting physics phenomena ranging from Mott insulators to topological insulators. Here, the authors use resonant inelastic X-ray scattering to study the low-energy excitations of the Mott insulator, Ca2RuO4, and reveal the orbital character of the magnetic properties of the system.

Genome-wide association studies (GWAS) have so far uncovered more than 200 loci for multiple sclerosis (MS). Here, the authors integrate data from various sources for a cell type-specific pathway analysis of MS GWAS results that specifically highlights the involvement of the immune system in disease pathogenesis.

Hechenleitner et al. describe two new titanosaurians and the finding of numerous accumulations of titanosaurian eggs in La Rioja, Argentina. This study suggests nesting site philopatry among Titanosauria and that this clade was spread throughout southern South America at the end of the Late Cretaceous.

The accurate determination of quark mixing parameters is essential for the understanding of the Standard Model. The LHCb collaboration now reports the coupling strength of the b quark to the u quark through the measurement of a baryonic decay mode.

CP violation has deep implications for particle physics and cosmology. Previously observed only in meson decays, signs of CP violation have now been spotted in baryon decays by analysing the proton–proton collision data from the LHCb detector.

Neurexins are essential presynaptic cell-adhesion molecules whose biological significance is poorly understood. Here, the authors interrogate Nrxn3 function in two brain regions, using two types of preparations and in three mutant mouse lines, and find that Nrxn3 plays mechanistically distinct, brain region-specific functions to regulate either presynaptic release or AMPA receptor stability.

Biofouling, or the unwanted growth of biological organisms, is a particular problem in marine environments. This review considers recent advances in the development of environmentally friendly coatings to combat biofouling of submerged surfaces.

Carbon dioxide (CO₂) capture and conversion provide an alternative approach to synthesis of useful fuels and chemicals. Here, Ye et al. give a comprehensive perspective on the current state of the art and outlook of CO₂ catalytic hydrogenation to the synthesis of light olefins, dimethyl ether, liquid fuels, and alcohols.

Deep-Manager is a software platform that enables efficient selection of features with lower sensitivity to unspecified disturbances across sets of similar experiments in bioimaging.
