Forest canopy openings may be caused by planned human intervention or by drivers such as fire, wind disturbance and pest outbreaks. Here, the authors present a high-resolution map and attribution analysis showing that planned and unplanned canopy openings often co-occur in European forests.
Classical photochemistry requires nanosecond excited-state lifetimes for diffusion-controlled reactions. Here the authors provide direct evidence for the elusive pre-association between radical ions and substrate molecules, enabling photoinduced electron transfer beyond the diffusion limit.
Developing mild photocatalytic bromination strategies using sustainable bromo source has been attracting intense interests, but there is still much room for improvement. Here, the authors report heterogenous organophotocatalytic HBr oxidation coupled with oxygen reduction to furnish Br2 and H2O2 for effective bromination of arenes.
Transition metal perovskite oxide membranes are promising platforms for infrared polaritonics. Here, the authors experimentally demonstrate highly confined epsilon-near-zero modes and propagating surface phonon polaritons in high-quality SrTiO3 membranes with deep subwavelength thickness.
The reduction in geometrical fill factor in stretchable organic light-emitting diodes (OLEDs) limits their potential for applications. Here, authors report a 3D architecture adopting a hidden active area as both emitting area and interconnector, realizing OLEDs with high post-stretch fill factor.
Mycoviruses are obligate parasites of fungi. Here, Hai et al. show that mycoviruses can induce hypovirulence in the fungus Sclerotinia, and plants infected by Sclerotinia facilitate the transmission of these mycoviruses, thereby helping the plants defend against Sclerotinia.
Due to the abundance of pathogenic variants in Peripherin-2, causing peripherin-2-associated inherited retinal disorders, and the lack of any approved treatment, it is imperative to identify an effective therapeutic strategy. Here the authors show that reducing rhodopsin levels improves retinal function and structure and decreases inflammatory responses.
Intracellular potassium (K+) homeostasis is achieved by activity of both ion channels and transporters. Here, the authors report structures of E. coli glutathione (GSH)-gated K+ efflux transporter KefC with bound K+ and conclude that the ion-binding site is adapted for binding a dehydrated ion.
Recognition on sources of hexachlorobutadiene is needed for their global control. This study clarifies hexachlorobutadiene emission factors from 121 industrial plants assigned to 12 industries and establishes their global emission inventory.
Network memory impacts dynamical processes emerging in real-world social systems, however little is known about memory of temporal networks beyond pairwise interactions. The authors develop a framework to characterize the temporal organization of higher-order networks and propose a model of temporal hypergraphs with higher-order memory to reproduce the patterns emerging in real-world complex systems.
Via specific acid etching, the authors report the production of spatially differentiated Bi4Ti3O12 nanosheets to accelerate photogenerated charge transfer and separation for effective water splitting in a one-step excitation system with a solar-to-hydrogen efficiency of 0.1%.
Halogen bond is desired for tuning electronic properties by external stimuli. Here, authors reveal a sequential activation of spin crossover and dimer softening, unveiling a key transient state in a prototypical halogen-bonded material.
Ultrasound neuromodulation overcomes limitations of electrode-based stimulation through improved
targeting and long-term stability for treating neurological disorders. Here, authors present a hair-thin, implantable piezoelectric stimulator that selectively modulates neurons in the deep brain.
The overexpression of the ecotropic viral integration site-1 gene (EVI1/MECOM) marks the most lethal acute myeloid leukemia subgroup carrying 3q26 abnormalities. Here, pan-histone deacetylase inhibitors are identified as potent repressors of EVI1 and PA2G4 as a druggable target.
Biased medical artificial intelligence systems pose significant potential risks to achieving fair and equitable healthcare. Here, we demonstrate a fairer ophthalmology AI that mitigates sexism and ageism through implicit fairness learning.
This study reveals that in the alpha-proteobacterium, Caulobacter crescent, a two-tier regulation by transcriptional activation and anti-termination coordinates the synthesis of phage-like Gene Transfer Agents (GTA) particles.
The effects of different choices on preprocessing pipelines for functional connectomics remain unclear. Here, the authors systematically evaluate a multitude of pipelines on resting-state fMRI, revealing a number of optimal pipelines for functional brain network analysis.
Fractured long bones regenerate through osteo-angiogenic coupling, but how calvarial bone healing occurs is not yet clear. Here they show that regenerating blood vessels separate from co-migrating progenitors in calvarial bones, resulting in osteoblasts mineralizing a previously vascularized lesion.
