The emerging pathogenic coronavirus hCoV-EMC, first identified in September 2012, has been fatal in about half of the few humans infected so far. Bart Haagmans and colleagues have now identified the receptor that this virus uses to infect cells. In contrast to the related virus SARS-CoV, which uses angiotensin converting enzyme 2, the functional receptor for hCoV-EMC is dipeptidyl peptidase 4 (DPP4, also known as CD26), an exopeptidase found on non-ciliated cells in the lower respiratory tract. This enzyme is highly conserved across different species, and hCoV-EMC can also use bat DPP4 as a functional receptor a possible clue as to the host range and epidemiological history of this new virus. The findings may also be important for the development of intervention strategies. The cover represents dipeptidyl peptidase 4 (red), the functional coronavirus-EMC receptor, on non-ciliated cells but not on ciliated cells (yellow) in primary bronchiolar epithelial cell cultures.

    Intracellular membrane potential changes are measured directly in mouse grid cells during navigation along linear tracks in virtual reality; the recordings reveal that slow ramps of depolarization are the sub-threshold signatures of firing fields, as in attractor network models of grid cells, whereas theta oscillations pace action potential timing.

    Gold

    Prized since antiquity for its beauty and stability, gold is becoming a darling of the nanotechnology age. Gold nanoparticles can help pinpoint a tumour — and then carry drugs to it. It also holds promise for making extremely efficient solar cells, among other photonic applications. Nature Outlook: Goldreports on what's driving the twenty-first-century gold rush.
