From 2D to 3D: Strain- and elongation-free topological transformations of optoelectronic circuits [Engineering]
Optoelectronic circuits in 3D shapes with large deformations can offer additional functionalities inaccessible to conventional planar electronics based on 2D geometries constrained by conventional photolithographic patterning processes. A light-sensing focal plane array (FPA) used in imagers is one example of a system that can benefit from fabrication on curved surfaces….

Crystal structure of MICU2 and comparison with MICU1 reveal insights into the uniporter gating mechanism [Biochemistry]
The mitochondrial uniporter is a Ca2+-channel complex resident within the organelle’s inner membrane. In mammalian cells the uniporter’s activity is regulated by Ca2+ due to concerted action of MICU1 and MICU2, two paralogous, but functionally distinct, EF-hand Ca2+-binding proteins. Here we present the X-ray structure of the apo form of…

Dynamically stiffened matrix promotes malignant transformation of mammary epithelial cells via collective mechanical signaling [Engineering]
Breast cancer development is associated with increasing tissue stiffness over years. To more accurately mimic the onset of gradual matrix stiffening, which is not feasible with conventional static hydrogels, mammary epithelial cells (MECs) were cultured on methacrylated hyaluronic acid hydrogels whose stiffness can be dynamically modulated from “normal” (<150 Pascals)…

Inhibition of EZH2 prevents fibrosis and restores normal angiogenesis in scleroderma [Medical Sciences]
Scleroderma (SSc) is a complex disease that involves activation of the immune system, vascular complications, and tissue fibrosis. The histone methyltransferase enhancer of zeste homolog 2 (EZH2) mediates trimethylation of lysine 27 of histone 3 (H3K27me3), which acts as a repressive epigenetic mark. Both EZH2 and H3K27me3 were elevated in…
