Solvent engineering by the addition of 1,4-butane sultone in a perovskite precursor solution simultaneously enhances the crystallization of the perovskite and passivates defects, resulting in a power conversion efficiency of 26.5%.

Liver endothelial cells respond differentially to various insults, influencing the liver’s niche and disease outcomes. Here the authors show that in response to bile acid chenodeoxycholic acid during cholestasis, endothelial Myc activation triggers P-selectin expression, promoting neutrophil infiltration and liver damage.

The synthesis of giant molecule acceptors with more than two subunits was challenging. Here, the authors present a stepwise precise synthetic method for acceptors of this type, explore and compare their photovoltaic performance to those of polymerized small molecule acceptor for organic solar cells.

High-pressure diamond anvil cell experiments reveal that compression strengthening of nanocrystalline nickel increases as its grain sizes decrease to 3 nanometres, owing to dislocation hardening and suppression of grain boundary plasticity.

Minimizing the non-radiative energy loss without sacrificing the charge collection efficiency is the key to improve the performance of organic solar cells. Here, the authors develop hybrid side chain-based asymmetric small molecule acceptors and achieve maximum power conversion efficiency of 19.76%.

Achieving efficient photoelectrochemical cells requires insights into the ion kinetics at the surface of photoelectrode. Here, the authors show a new platform for investigating strong coupling between hydroxide ions and surface charge carriers by using monolayer InSe as the anode with high photocurrent density.

Evolution of accretion disk and corona during outbursts in black hole binary systems is still unclear. Here, the authors show spectral analysis of MAXI J1820+070 and propose a scenario of a dynamical corona to explain the evolution of the reflection fraction observed by Insight-HXMT.

Catalytic and enantioselective construction of chiral α,α-dialkyl indoles represents an important yet challenging objective to be developed. Herein the authors describe a cobalt catalyzed enantioselective anti-Markovnikov alkene hydroalkylation via the remote stereocontrol for the synthesis of α,α-dialkyl indoles and other N-heterocycles.

The seas of the Mesozoic were populated by marine reptiles, yet their modes of locomotion remain unknown. Here, Zhang et al. describe seabed tracks made by the paddles of Middle Triassic nothosaurs in southwestern China, which shows that these marine reptiles used their forelimbs for propulsion.

Molecular level control is required to capture the folding and supramolecular assembly of collagen in mimetic materials. Here, the authors report on the creation of a synthetic collagen which assembles into banded fibers, recaptures structural properties of natural collagen and which can act as a testbed for design and experimentation

Continuous monitoring of intraocular pressure remains a grand challenge in glaucoma care. Here the authors develop smart soft contact lenses for continuous 24-hour monitoring of intraocular pressure in human eyes, even during sleep.

Human pan-genomics are increasing our knowledge of genomic diversity and genetic factors in disease. Here, the authors built a gastric cancer pan-genome that included the sequences of Chinese Han patients, and predicted putative and previously unaligned genes associated with gastric cancer.

The host blood-type-associated ABO genotype affects the abundance of specific bacteria in the pig intestine.

A new surface passivator cyclohexane 1,4-diammonium diiodide naturally contains two isomeric structures with ammonium groups on the same or opposite sides of the hexane ring, and the two isomers demonstrate completely different surface interaction behaviours.

The modification of small molecule acceptor building block and π−bridge linker is effective to improve photovoltaic performance. Here, the authors replace linear with branched alkyl chains and introduce difluorene-substituted linker to realise all-polymer solar cells with efficiency of 17.24%.

How to facilitate the transcription of plant-specific RNA Pol V is largely unknown. Liu et al. find that a conserved RNA Pol II elongator, SPT6L, mediates DNA methylation by its association with Pol V and promoting the production of scaffold RNA.

Whether a polymorphic transition exists in high entropy alloys or not remains unclear since discovery of these alloys more than a decade ago. Here authors report an irreversible polymorphic transition fromfcc to hcp in the prototype FeCoCrMnNi high entropy alloy and provide evidence for fccphase being more stable than hcp phase only at high temperatures.

Through development of non-fullerene acceptors, OPVs have reached efficiencies of 18%, yet the inadequate operational lifetime still poses a challenge for the commercialisation. Here, the authors investigate the origin of instability of NFA solar cells, and propose some strategies to mitigate this issue.

Analyses of genetic variation and population structure based on over 3,000 cultivated rice (Oryza sativa) genomes reveal subpopulations that correlate with geographic ___location and patterns of introgression consistent with multiple rice domestication events.

Development of tandem organic solar cells has been limited by the choice of near-infrared absorbing materials for the rear cell. Here, the authors report a simple strategy to extend the conjugation length of acceptor Y6 and broaden its absorption range to near-infrared region. A tandem organic solar cell with efficiency of 16.4% was achieved.

This study demonstrates that lipopolysaccharide promotes activation of the JNK signaling pathway and endogenous TNF-α secretion in pulmonary macrophages, which facilitates lung fibroblast aerobic glycolysis and lactate production through PFKFB3 activation. These findings suggests that inflammation-metabolism interactions between lung macrophages and fibroblasts might play an essential role in lipopolysaccharide-induced pulmonary fibrosis.

A major problem in the clinical management of patients with brain tumors is distinguishing tumor recurrence from radiation-induced necrosis after brain tumor therapy. Zhou et al. use an MRI technique called amide proton transfer imaging to noninvasively differentiate between these two pathologies. The approach is successfully evaluated by comparing two orthotopic glioma models with a radiation necrosis model in rats.
