  • This study presents evidence that siRNAs or miRNAs with seed sequences that overlap RBP motifs have extended biological effects by perturbing RBP activity. Seed-to-RBP crosstalk contributes to off-target activity and growth phenotype modulation.

  • Electrochemical CO reduction to multi-carbon products offers a carbon-negative approach to produce chemicals, but the intricate reaction pathways lead to a broad spectrum of products. Now it has been shown that alkali cations alter the mechanistic pathways that govern the reaction selectivity involved in the formation of hydrocarbons versus oxygenates.

  • Selective catalytic oxidation (SCO) of NH3 to N2 is a highly effective approach for reducing NH3 emissions, though achieving high conversion across a broad temperature range without over-oxidation to NOx remains challenging. Here, the authors introduce a bi-metallic surficial Pt-Cu catalyst that effectively removes NH3 from both stationary and mobile exhaust sources via SCO.

  • Ethylene glycol is a commodity chemical with an annual consumption of 20 million tonnes. Its production generates 1.6 tonnes of CO2 per tonne of ethylene glycol.

  • Au/C single-site catalysts have been validated commercially for acetylene hydrochlorination, but they have previously been prepared using highly oxidizing acidic solvents or additional ligands. It has now been shown that they can be made by impregnation of a metal salt from an acetone solution—generating catalysts with comparable activity to those synthesized by the other methods.

  • LKB1 tumour suppressor gene is frequently mutated in lung adenocarcinoma. Here the authors show that in genetically engineered mouse models of lung cancer Lkb1 restoration induces growth arrest and drives neoplastic cells toward a more differentiated and less proliferative alveolar type II cell-like state via C/EBP-mediated reprogramming.

  • This large-scale analysis of copy number alterations (CNAs) in patient-derived xenografts (PDXs) across 24 cancer types shows that new CNAs accumulate quickly and that the specific CNAs acquired during passaging differ from those acquired during tumor evolution in patients, suggesting that PDX tumors are under distinct selection pressures from tumors in human hosts.

  • RNA silencing through small RNAs is a major antiviral immunity system in plants. Recent findings are uncovering the roles of RNA silencing in immunity against non-viral pathogens, which is mediated by trans-kingdom RNA movements in vesicles or as extracellular nucleoproteins. RNA silencing also enables the crosstalk between other plant immunity systems.
