    Generating electricity by low-grade thermal harvesting requires a low-cost technology. Here, by chemically treating wood, aligned cellulose molecular chains form that confine sodium ions in the sub-nanometre channels and enhance selective diffusion, generating differential thermal voltage of 24 mV K–1.

    Crosstalk between microtubules and the actin cytoskeleton of cells is important in elucidating integrin-mediated adhesion and mechanotransduction. It is now shown that microtubule-mediated control of focal adhesions and podosomes occurs via KANK family proteins.
