Ovarian and endometrial cancers with CCNE1-amplification are often resistant to standard treatment. Here, the authors identify that CCNE1-amplified gynecological cancer is sensitive to combined PKMYT1 and ATR inhibition via CDK1 activation, resulting in premature mitosis, DNA damage, cell apoptosis and reduced tumour growth and metastasis.

Stress can increase the consumption of rewarding food, which contributes to obesity and binge eating disorders. Here the authors show that stress eating depends on a strengthened connection between the lateral hypothalamus and the dopamine system.

Pollinator loss is a concern but data on their status is lacking. Here Powney et al. use occupancy modelling to estimate the degree of loss in wild bee and hoverfly species across Great Britain, and report a 55% decline in upland species and a 12% increase in dominant crop pollinators.

Isoprene emissions are commonly estimated using satellite measurements and model simulations. Here, using eddy covariance, the authors report higher emission rates over the Amazon forest than those estimated with these techniques and a relationship between terrain elevation and isoprene emissions.

In a single-arm phase 2 trial evaluating intravesical delivery of the oncolytic adenovirus cretostimogene grenadenorepvec with systemic anti-PD-1 in patients with BCG-unresponsive non-muscle-invasive bladder cancer with carcinoma in situ, the complete response rate at 12 months was 57.1%, meeting the primary endpoint.

Unimolecular integration of NMDA receptor antagonism with GLP-1 receptor agonism effectively reverses obesity, hyperglycaemia and dyslipidaemia in rodent models of metabolic disease.

Knowing the age of malaria-transmitting mosquitoes is important to understand transmission risk as only old mosquitoes can transmit the disease. Here, the authors develop a method based on mid-infrared spectra of mosquito cuticle that can rapidly identify the species and age class of main malaria vectors.

BRAF inhibitors often show skin-hyperproliferative side effects in melanoma patients. Here, the authors demonstrate that BRAF inhibitors can be used to enhance skin wound healing through the MAPK- ERK pathway activation that positively regulates the proliferation of keratinocytes.

Time-series data from tropical forests tracking weather and declines in arthropod diversity and function show that fluctuations in species were largely dependent on their El Niño sensitivity and ecological specialization.

In this study, Marlin et al. provide insights into the potential use of subunit vaccines that induce a high level of protection against SARS-CoV-2 in animal models.

Parity induces an accumulation of CD8⁺ T cells, including cells with a tissue-resident-memory-like phenotype within human normal breast tissue, offering long-term protection against triple-negative breast cancer.

Llorente, Blasco, Espuny and colleagues show that MAF regulates the genomic distribution of ERα and modulates the expression of metastasis genes via KDM1A, thereby driving metastatic spread in breast cancer.

HER2-enriched breast cancers within the HER2-positive subtype are addicted to the HER2 pathway. Here, the authors analyse gene expression before, during, and after treatment with anti-HER2-based therapies in the phase II PAMELA clinical trial, finding phenotypic changes induced by treatment.

This study uses a novel vascular model with human induced pluripotent stem cell-derived endothelial cells, pericytes, and smooth muscle cells to explore the vascular complications associated with SARS-CoV-2. It reveals that smooth muscle cells as the primary sites of infection and inflammation.

There is a requirement for improved adjuvants to improve responses to vaccines, including adjuvants that induce Th17 cells. Here, the authors use a MINCLE and TLR9 agonist-based vaccine adjuvant and show induction of Th17 and mucosal immune responses to vaccine recall antigens in mice and non-human primate models of vaccination.

Hydroxychloroquine did not confer protection against SARS-CoV-2 infection or reduce the viral load after infection in macaques; these findings do not support the use of hydroxychloroquine as an antiviral drug treatment of COVID-19 in humans.

Increasing evidence point to a dysfunction of the nucleus accumbens (NAc) in eating disorders. Here, the authors provide evidence that dysregulation of the activity of NAc dopaminoceptive neuronal subpopulations is sufficient to alter energy balance.

Variants of the 3′−5′ exonuclease TREX1 can cause retinal vasculopathy with cerebral leukoencephalopathy (RVCL). Here, the authors show that RVCL-associated TREX1 variants trigger DNA damage in humans, mice, and Drosophila, and render cells more vulnerable to DNA damage inducing agents.

A comprehensive multi-omics reference atlas of prenatal human skin shows that innate immune cells crosstalk with non-immune cells to perform pivotal roles in skin morphogenesis, including the formation of hair follicles.

Ancient DNA reveals genetic differences between stone-tool users and people associated with ceramic technology in the Caribbean and provides substantially lower estimates of population sizes in the region before European contact.

It remains unclear how rapid antibiotic switching affects the evolution of antibiotic resistance in individual patients. Here, Chung et al. combine short- and long-read sequencing and resistance phenotyping of 420 serial isolates of Pseudomonas aeruginosa collected from the onset of respiratory infection, and show that rare resistance mutations can increase by nearly 40-fold over 5–12 days in response to antibiotic changes, while mutations conferring resistance to antibiotics not administered diminish and even go to extinction.

On the anniversary of the Boyden et al. (2005) paper that introduced the use of channelrhodopsin in neurons, Nature Neuroscience asks selected members of the community to comment on the utility, impact and future of this important technique.

Diversity within terrestrial tetrapod communities has risen by at most threefold over the last 300 million years, consistent with a constrained model of diversification.

LKB1 is frequently mutated in lung squamous cell carcinomas. Here, the authors show that sole LKB1 depletion is sufficient to drive the development of this cancer, where downstream defective MKK7-JNK1/2 signalling activates the ∆Np63/p63 pathway to induce subsequent epithelial cells transformation and tumour progression.
