Fission and reconfiguration of bilobate comets as revealed by 67P/Churyumov–Gerasimenko

The solid, central part of a comet—its nucleus—is subject to destructive processes, which cause nuclei to split at a rate of about 0.01 per year per comet. These destructive events are due to a range of possible thermophysical effects; however, the geophysical expressions of these effects are unknown. Separately, over two-thirds of comet nuclei that have been imaged at high resolution show bilobate shapes,...

A mechanism of viral immune evasion revealed by cryo-EM analysis of the TAP transporter

Cellular immunity against viral infection and tumour cells depends on antigen presentation by major histocompatibility complex class I (MHC I) molecules. Intracellular antigenic peptides are transported into the endoplasmic reticulum by the transporter associated with antigen processing (TAP) and then loaded onto the nascent MHC I molecules, which are exported to the cell surface and present peptides to the immune system. Cytotoxic T lymphocytes...

Final Fantasy VII Remake gameplay revealed at PlayStation Experience keynote

SAN FRANCISCO—Last year's inaugural PlayStation Experience closed 2014 with a surprising number of game and product announcements, and Sony appeared ready to double-down on this new end-of-year tradition with a follow-up, fan-focused convention full of playable demos and new products, and its two-hour keynote led off with the big Final Fantasy remaster that Sony announced at this past summer's Electronic Entertainment...
