Crystallization in one-step solution deposition of perovskite films: Upward or downward?
3hDespite the fast progress of perovskite photovoltaic performances, understanding the crystallization and growth of perovskite films is still lagging. One unanswered fundamental question is whether the perovskite films are grown from top (air side) to bottom (substrate side) or from bottom to top despite 10 years of development. Here, by using grazing incidence x-ray diffraction and morphology cha
Making climate projections conditional on historical observations
3hMany studies have sought to constrain climate projections based on recent observations. Until recently, these constraints had limited impact, and projected warming ranges were driven primarily by model outputs. Here, we use the newest climate model ensemble, improved observations, and a new statistical method to narrow uncertainty on estimates of past and future human-induced warming. Cross-valid
Confinement-induced self-organization in growing bacterial colonies
3hWe investigate the emergence of global alignment in colonies of dividing rod-shaped cells under confinement.

This behavior crucially relies on the co
Molecular design of stapled pentapeptides as building blocks of self-assembled coiled coil-like fibers
3hPeptide self-assembly inspired by natural superhelical coiled coils has been actively pursued but remains challenging due to limited helicity of short peptides.

Here, we demonstrate the feasibility of this desi
Exosomal delivery of NF-{kappa}B inhibitor delays LPS-induced preterm birth and modulates fetal immune cell profile in mouse models
3hAccumulation of immune cells and activation of the pro-inflammatory transcription factor NF-B in feto-maternal uterine tissues is a key feature of preterm birth (PTB) pathophysiology. Reduction of the fetal inflammatory response and NF-B activation are key strategies to minimize infection-associated PTB. Therefore, we engineered extracellular vesicles (exosomes) to contain an NF-B inhibitor, term
Reconciling atmospheric CO2, weathering, and calcite compensation depth across the Cenozoic
