A direct comparison of stability data of perovskite solar cells is challenging due to widely different measurement conditions and reporting standards. Here, the authors propose a single indicator to assess the stability under different environmental stress and analyse the data of over 7000 devices.

While metal halide perovskite solar cells are extensively investigated in the lab their performance and degradation in real-world outdoor conditions are still poorly understood. Now, researchers propose a method to analyse field data to identify how and why the outdoor device performance changes over time.

Targeting neurons that regulate energy balance may offer new approaches for obesity treatment. Here, authors show that chemogenetic and pharmacological manipulation of GABAergic neurons in the DRN/vlPAG increases adaptive thermogenesis and reduces weight gain in mice fed a highfat diet.

Analysis of soundscape data from 139 globally distributed sites reveals that sounds of biological origin exhibit predictable rhythms depending on location and season, whereas sounds of anthropogenic origin are less predictable. Comparisons between paired urban–rural sites show that urban green spaces are noisier and dominated by sounds of technological origin.

A combination of measurements from the Solar Dynamics Observatory and radiospectroscopy data from the Nançay Radioheliograph now details the mechanism that connects coronal mass ejections from the sun and the acceleration of particles to relativistic speeds. A spatial and temporal correlation between a coronal ‘bright front’ and radio emissions associated with electron acceleration demonstrates the fundamental relationship between the two.

A black hole’s Hawking radiation inevitably deposits records of its location in the environment, making isolation fundamentally impossible. Here, the authors investigate the decoherence of a black hole in a superposition of two positions due to its Hawking radiation and give the rate of this process.

A combination of clonal expansion and DNA amplification is used to sequence genetic material from individual melanocytes, shedding light on the mutational landscape of these cells and the development of melanomas.

The magnetic flux rope is a crucial structure in astrophysical and space plasmas. Here, the authors show how this structure rapidly contracts/expands and consequently how it accelerates/decelerates electrons, by using an advanced analysis technique.

Multiple high-precision measurement campaigns at CERN of the antiproton-to-proton charge-to-mass ratio—to a precision of 16 parts per trillion—in a cryogenic multi-Penning trap offer no evidence of charge–parity–time violation, and set stringent limits on the clock-weak-equivalence principle.

The quark structure of the f₀(980) hadron is still unknown after 50 years of its discovery. Here, the CMS Collaboration reports a measurement of the elliptic flow of the f₀(980) state in proton-lead collisions at a nucleon-nucleon centre-of-mass energy of 8.16 TeV, providing strong evidence that the state is an ordinary meson.

Spin-flip resonance data are used to place direct constraints on the interaction of ultralight axion-like particles with antiprotons, improving the sensitivity to the corresponding coupling coefficient by five orders of magnitude.

The overlap between different phases has hindered the understanding of how each phase affects superconductivity in FeSe. Here, Matsuura et al. achieve a complete separation of non-magnetic nematic and antiferromagnetic phases for FeSe_1-x S _x , observing a tetragonal phase in between with a strikingly enhanced T _c.

Carbon materials are promising for perovskite solar cells but suffer from poor interfacial energy level alignment. Now, Zhang et al. show that Ti atomically dispersed in reduced graphene reduces energy losses improving device performance.

Tissue co-regulation score regression (TCSC) infers causal tissues and partitions trait heritability into tissue-specific components using a transcriptome-wide association study framework. Applying TCSC to 78 complex traits and diseases identifies biologically plausible tissue–trait relationships.

Metabolite signatures were identified for subtypes of dietary carbohydrate, including added sugar, whole grain and refined grain, and showed different associations with type 2 diabetes, providing an objective measure of dietary risk.

Trained and validated on multimodal data from 14.5 million images from multicountry datasets, a foundation model is shown to increase diagnostic and referral accuracy of clinicians when used as an assistant in a trial involving 16 ophthalmologists and 668 patients.

Electrocatalytic CO₂ reduction is typically studied at laboratory scale under ambient conditions; however, temperature and pressure may have a profound impact on the mechanism of this reaction and on its relevance to industrial applications. This study uses a custom temperature- and pressure-adjustable cell to reveal a chain growth mechanism emerging on copper electrodes at elevated temperatures and pressures.

Circadian dysfunction is a potential driver of eye aging. Here the authors report that in conjunction with the core molecular clock transcription factor Clock, dietary restriction promotes rhythmic homeostatic mechanisms within photoreceptors to delay visual senescence and extend lifespan in Drosophila Melanogaster.

Efficient voltage-controlled regulation of water and ion transport was achieved in stable Zr₄-Ti₃C₂T_x membranes. Under negative voltage, water diffusion was enhanced while ion transport was suppressed. This provides a promising strategy to overcome the intrinsic permeability– selectivity trade-off.

Long-term Doppler imaging of star spots can provide information about stellar dynamos. Here, the authors show 16 years of Doppler imaging of star XX Trianguli, which indicates chaotic nonperiodic dynamo.

Psoriasis is a partially heritable skin disorder, the genetic basis of which is not fully understood. Here, the authors use genome-wide association meta-analysis to discover psoriasis susceptibility loci and genes, which encode existing and potential new drug targets.

Quantifying recombination in halide perovskites is crucial, but quantitative analysis remains rare. Here the authors observe a long-lived and continuously changing photoluminescence decay time due to the high density of shallow defects and substantial rates of charge carrier trapping.

R9AP is a key receptor for entry of Epstein–Barr virus into human epithelial and B cells, and interacts directly with the viral glycoprotein gH/gL complex to mediate virus–host membrane fusion.

There is an abundance of solar observational data taken by various instrumentation with different quality and resolutions. Here, the authors provide a deep learning framework for instrument-to-instrument translation of solar observation data, enabling homogenized data series of multi-instrument data sets.

Barcoding aids in the optimization of lipid nanoparticles. Here, the authors report on multiplexed mRNA barcoding that enables high-resolution spatiotemporal profiling of lipid nanoparticles, linking accumulation kinetics to functional delivery and revealing zonal liver targeting.

As the Solar Orbiter spacecraft is scheduled for launch this month, European Space Agency (ESA) and NASA Project Scientists provide an overview of this major ESA–NASA mission to the Sun.

Unconventional oil and gas production has increased drastically in the US, but its environmental impacts are not well known. Here, the authors show that these wells can be associated with elevated levels of airborne particle radioactivity in downwind locations.

The NASA MESSENGER mission collected a rich dataset enabling determination of Mercury’s ephemeris. Here, the authors analyse MESSENGER data obtained over an extended period of time to quantify parameters related to General Relativity.

Here, authors study boulders’ fractures on S-type asteroid, Dimorphos, and show that their size-frequency distribution and orientation are consistent with formation through thermal fatigue. Such fractures seem to propagate horizontally much faster (~kyr) than normal to the boulder’s surface (~Myr).

The discovery of 2023 KQ₁₄, a Sedna-like object with a perihelion of 66 au, fills a gap in the known population. Its orbit does not align with other Sedna-like objects, shedding light on the diversity and dynamical history of the outer Solar System.
