Functional roles of interneurons in regulating the gain of place-tuned neurons are not fully understood. Here, the authors show that VIP neurons fine-tune brain circuits like amplifiers in electronics, using gain modulation to boost spatial signals. This effect enhances navigation signals in the neocortex but not the hippocampus, revealing region-specific control of information flow.

Ossenkoppele, Coomans and colleagues analyzed the tau PET data of 12,048 individuals from 42 cohorts worldwide. They found that age, amyloid-β status, presence of an APOE ε4 allele and female sex are key contributors to tau PET positivity, which should aid clinical decision-making and trial designs.

Active devices such as modulators made of silicon nitride still lack performance. Here, the authors demonstrate electro-optic modulators based on ferroelectric lead zirconate titanate films on silicon nitride, in both the O- and the C-band with a modulation bandwidth beyond 33 GHz and with data rates of 40 Gbps.

A neoadjuvant treatment regimen of anti-PD-L1 monotherapy followed by anti-PD-L1 plus chemotherapy was well tolerated and led to a major pathologic response rate of 70% in patients with resectable gastric or gastroesophageal junction adenocarcinoma.

Joris Veltman and colleagues apply exome sequencing to identify heterozygous de novo mutations in SETBP1 as the cause of Schinzel-Giedion syndrome, a rare sporadic disorder characterized by severe intellectual disability and multiple congenital malformations.

The device’s electroluminescence efficiency is vital to reduce non-radiative voltage losses and boost organic solar cell performance. Here, the authors demonstrate that this efficiency is influenced not only by the decay of charge transfer states but also by the dissociation of singlet states.

A manufacturable platform for quantum computing with photons is introduced and a set of monolithically integrated silicon-photonics-based modules is benchmarked, demonstrating dual-rail photonic qubits with performance close to thresholds required for operation.

From 1980 to 2018, the levels of total and non-high-density lipoprotein cholesterol increased in low- and middle-income countries, especially in east and southeast Asia, and decreased in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe.

Iatrogenic injury of the ureters is a feared complication of laparoscopic abdominal surgery. Here the authors present the NIR fluorophore ZW800-1 as an intraoperative imaging agent for ureter mapping, showing its safety, pharmacokinetic properties, and efficacy in healthy volunteers and patients undergoing abdominopelvic surgery.

Genome-wide analysis identifies variants associated with the volume of seven different subcortical brain regions defined by magnetic resonance imaging. Implicated genes are involved in neurodevelopmental and synaptic signaling pathways.

Environmental influences during prenatal development may have implications for health and disease later in life. Here, Czamara et al. assess DNA methylation in cord blood from new-born under various models including environmental and genetic effects individually and their additive or interaction effects.

Post-traumatic stress disorder (PTSD) is a common mental health problem. Here, the authors report a GWAS from the Psychiatric Genomics Consortium in which they identify two risk loci in European ancestry and one locus in African ancestry individuals and find that PTSD is genetically correlated with several other psychiatric traits.

Chromodomain Helicase DNA-binding (CHD) proteins have been implicated in neurodevelopmental processes. Here, the authors identify missense variants in CHD3 that disturb its chromatin remodeling activities and cause a neurodevelopmental disorder with macrocephaly and speech and language impairment.

Podosomes are actin-based protrusions used by cells for invasion and local degradation but the structure underlying their protrusiveness and mechanosensitivity is unclear. Here, the authors report that podosomes have a modular actin nano-architecture whose organization differs on stiff or soft substrates.

Catalytic iron is associated with intensive care unit mortality and is known to cause free radical-mediated cellular toxicity. Here the authors show that a soluble ferrostatin-analogue (a ferroptosis inhibitor) protects mice from injury and death in experimental iron overload induced and genetic models of organ dysfunction, but not sepsis-induced multiorgan dysfunction.

Copper-based catalysts are promising for electroreduction of carbon monoxide to multi-carbon products, yet further improvements in selectivity, productivity and stability are still needed. Here the authors show that doping copper with silver and ruthenium boosts its performance towards synthesis of n-propanol—a useful fuel.

The electroreduction of CO₂ offers a promising approach to produce carbon-neutral methane using renewable electricity. This study shows that the introduction of Au in Cu enables selective methane production from CO₂ by regulating *CO availability.

The performance of organic semiconductor devices depends heavily on molecular parameters. Here, Schwarze et al. point out that the molecular quadrupole moment largely influences device energy levels and show how quadrupole moments can reduce the energy barrier for charge generation in solar cells.

The majority of skeletal dysplasia are caused by pathogenic variants in genes required for glycosaminoglycan (GAG) metabolism. Here, Dubail et al. identify genetic variants in the solute carrier family protein SLC10A7 in families with skeletal dysplasia and amelogenesis imperfecta that disrupt GAG synthesis.

MADS-box genes regulate flowering plant development, but their evolutionary origins are unclear. Here, Ruelens et al.show that three major, apparently flowering plant-specific, MADS-box gene clades are derived from a single ancestral tandem duplication, and identify FLOWERING LOCUS C-like genes in cereals.

The neurotransmitter noradrenaline can regulate cellular processes that contribute to cancer progression, but the underlying mechanisms remain largely unknown. Here the authors identify Src as a key mediator of noradrenaline signalling networks in tumour metastasis.

The effective control of chirality on surfaces is crucial for applications such as enantioselective heterogeneous catalysis and nonlinear optics. Here, the authors study the on-surface synthesis of organometallic polymers and their chiral expression on Ag(110), demonstrating that kinetic effects play an important role in determining polymer chirality.

Contrary to the view that urbanization is a major driver of the global rise in obesity, the global increase in body-mass index is shown to be mostly due to increases in the body-mass indexes of rural populations.
