A novel single-objective light-sheet microscope with unparalleled spatiotemporal resolution enables imaging and optical manipulation of diverse biological specimens and processes.
Nuclear pores assemble asymmetrically, by an inside-out evagination of the inner nuclear membrane that grows in diameter and depth until it fuses with the flat outer nuclear membrane.
Organoids developed from matched human placental tissue define differences in antiviral signaling between cell types comprising the maternal-fetal interface.

While the transcription factor c-Myc explores the space in the nucleus in an unrestricted manner, the elongation factor P-TEFb's sampling of the nucleus is constrained to a complex domain with fractal characteristics.
SIMC1 and SLF1 bind exclusively to SLF2 to form two separate complexes that direct the human SMC5/6 complex to its antiviral defense or DNA lesion repair activities.
A key cellular stress granule protein, G3BP1, is critical for efficient norovirus infection, representing the first pan-norovirus, pro-viral factor identified to date.
