Cellular Wonders Coming Into Focus

At higher magnifications, the cell’s nano machines become even more spectacular.

[Note: CEH is taking a break this week. These news items are presented for those who wish to follow up on them.]

Energy powerhouses of cells come into focus (Science Magazine).

Elastic coupling power stroke mechanism of the F1-ATPase molecular motor (PNAS).

Structure, mechanism, and regulation of the chloroplast ATP synthase (Science Magazine).

High-resolution cryo-EM analysis of the yeast ATP synthase in a lipid membrane (Science Magazine).

Efficient coding explains the universal law of generalization in human perception (Science Magazine).

Ion-triggered selectivity in bacterial sodium channels (PNAS).

Laterally confined growth of cells induces nuclear reprogramming in the absence of exogenous biochemical factors (PNAS).

Stomata—the plant pores that give us life—arise thanks to a gene called MUTE (Phys.org).

Physics of lumen growth (PNAS). “The development of intercellular cavities (lumens) is a ubiquitous mechanism to form complex tissue structures in organisms.”

Fractal-like hierarchical organization of bone begins at the nanoscale (Science Magazine). “The components of bone assemble hierarchically to provide stiffness and toughness.”

We hope to return to our regular reporting shortly. Thank you for your patience.
