Anti-Kasha processes have potential in organic luminogens, but design of materials with these characteristics is challenging. Here, the authors report the development of a host-guest system with anti-Kasha behaviour and triplet energy transfer.

“Cycloparaphenylenes consisting of are cyclic π-conjugated structures presetting interesting physical properties upon functionalization. However, the ring strain and steric hindrance of the substituents hamper the functionalization of small sized cycloparaphenylenes. Here, the authors describe a [6]cycloparaphenylene with twelve methoxy units employed to form a rotaxane with in-plane aromaticity upon oxidation.”

Contact electrification triggers gas breakdown. Using Coulomb force to estimate voltage, this work provides experimental evidence for the Paschen curves that govern such discharge.

W. X. Zhao et al. study the higher-order topological insulator candidate Bi₄Br₄ by angle-resolved photoemission spectroscopy (ARPES) and ab-initio calculation. They provide strong evidence for the higher-order topological insulator phase, including a signature of the hinge states inside the (100) surface gap.

Designing stable Ru-based catalysts for acidic oxygen evolution remains a challenge. Here, the authors propose an oxyanion protection strategy to prevent the formation of oxygen vacancies on the RuO₂ surface by creating coordination-saturated lattice oxygen, thereby greatly enhancing the stability.

The coal chemical sector uses coal to produce chemicals and emits substantial greenhouse gases, which are hard to abate by electrification alone. Deploying green H₂ for China’s coal chemical plants can reduce ~50% of emissions at a low cost.

Deciphering the relationship between prolonged topographic growth and temporary earthquake uplift is challenging due to the mismatch in their deformation patterns. Zhang et al. introduce a novel model to address this highly hotly-debated discrepancy.

Ecological restoration success may depend on interactions between multiple trophic levels. Here, the authors show that top-down control of crab grazers by shorebirds could help rebuild wetland multifunctionality after invasive cordgrass eradication.

A characteristic of costal-pelagic fishes is their large population size fluctuations, yet the drivers remain elusive. Here, the authors analyze a 45-year timeseries of nitrogen stable isotopes measured in larvae of Northern Anchovy and find that high energy transfer efficiency from the base of the food web up to young larvae confers high survival and recruitment to the adult population.

Forecasting ecology can support proactive decision-making in the face of uncertain environmental conditions. Using case studies on whale entanglement and sea turtle bycatch, this study showcases the capacity for existing management tools to transition to a forecast configuration and provide skilful forecasts up to 12 months in advance.

Here the authors report a new approach to profile RNA-RNA interactions in live bacterial cells. The charted RNA interaction networks unveil a key mRNA regulatory hub targeted by twelve small RNAs, including a novel RNA involved in fatty acid metabolism.

The expansion of cells with TET2 mutations within the blood is associated with increased risk for all-cause mortality, development of leukemia and cardiovascular disease. Here authors show IL1 promotes the clonal expansion TET2 knockout cells, enhancing their self-renewal, promoting their myeloid bias and impairing an IL1 driven loss of methylation at lymphoid and erythroid regulatory elements.

Previous work has identified cells in L2/3 of auditory cortex which strongly respond with bursting to a specific learned chord, but not to single component tones in an auditory task. Here the authors show that these cells correlate with the behavioral relevance of the learned composite sounds.

It has been proposed that the amygdala is required for the familiarity aspect of item recognition. By studying the performance of monkeys with selective amygdala lesions on four converging memory paradigms, the authors demonstrate that the amygdala is not necessary for familiarity memory, but confirm its role in reward processing.

Here, authors report demineralized bone paper-based in vitro osteogenic culture and assay platforms that replicate essential bone tissue complexity, osteoclast processes, and drug responses with high fidelity and predictive power.

A systemically administered peptide (CARSKNKDC) that homes to injured tissues, has inherent ability to promote wound healing. Here, the authors show that this peptide binds to syndecan-4 and activates ARF6 to trigger re-epithelialisation and the naturally occurring wound repair pathway.

The mechanism underlying thyroid follicle formation is not well understood. Here, the authors show that a subgroup of NF-κB-activated thyrocytes, through interactions with myeloid cells, exhibit increased migration capacity to generate new follicles.

Gene editing strategies for cystic fibrosis are challenging. Here the authors improve on their previously reported shuttle peptide noncovalently combined with Cas ribonucleoprotein (RNP), and derive the S315 peptide for delivery: they show base editing in the respiratory tract of the rhesus macaques.

In patients with CKD, there is an unmet need for biomarkers that reliably track kidney injury. Here, in a series of prospective studies, the authors show that retinal OCT metrics reflect kidney injury, are modified by treatments for kidney disease and can predict future decline of kidney function.

The emissions pathways of most publicly traded companies in high-emitting sectors are not aligned with the climate targets of the Paris Agreement. An extensive analysis of companies’ sustainability behaviour offers insights into why this is the case.

Most inhabited areas in the US have more mass in buildings and mobility networks than in plant biomass. Cities are comparably resource efficient, while high material intensity is found in rural areas. Migration reinforces this phenomenon as people leave while built structures remain.

Risk of isolation is expected to disproportionately affect racial minority populations in the U.S. as sea level rise increases. Communities with more renters, older adults, and lower-income populations will also be impacted.

A new study explores the global feasible supply of steel and cement within Paris-compliant carbon budgets, explicitly considering uncertainties in the deployment of infrastructure and it shows that feasible supply may fall short of expected global demand.

Social networks often segregate based on political identities. We show that such segregation is reduced when people know how others behave towards those from their outgroup and ingroup
