  • Ridges and valleys in many landscapes are uniformly spaced, but no theory has predicted this fundamental topographic wavelength. A characteristic length scale is now derived from equations of mass conservation and sediment transport; it is found to be directly proportional to the valley spacing in models of landform evolution, and to the measured valley spacing at five study sites in the USA.

  • The surface of Mars has a set of features that ring the plains for thousands of kilometres, which have been interpreted as a series of former shorelines. But topographic profiles along the putative shorelines contain long-wavelength trends in elevation that have been taken as an argument against the shoreline (and ocean) hypothesis. This paper demonstrates that true polar wander could bring the elevations of the proposed shorelines into line, reviving the ocean hypothesis.

  • Flowing water shapes most of Earth's canyons, obscuring the contributions of other erosional mechanisms. A comparison of adjacent canyons with and without wind shielding shows that wind can amplify canyon incision on windblown Earth and Mars.

  • A fresh look at the Channeled Scablands of North America shows that the ancient floods that scarred that landscape were smaller than is commonly assumed. This result could revise estimates of similar floods on Mars. See Letter p.229

  • Meta-regression of trials using carotid intima–media thickness (CIMT) as a surrogate end point leads to unreliable results owing to heterogeneity in methods, interventions, and outcomes of pooled trials. CIMT will continue to be a worthwhile surrogate trial end point supported by two decades of technical progress and clinical atherosclerosis research.

  • Topographic analyses and numerical modelling of canyon formation across the Hawaiian island of Kaua‘i show that rivers erode into bedrock more efficiently where precipitation rates are higher.

  • Models and field measurements together show that the branching patterns of fine-scale river networks are the result of coupled instabilities in the erosional processes that drive valley incision.

  • Autophagy is a ubiquitous cellular catabolic process responsive to energy stress. Activation of autophagy is cardioprotective in some settings (ischaemia and ischaemic preconditioning), but sustained autophagy has been linked with cardiopathology in other settings (prolonged pressure overload and heart failure). In this Review, induction of autophagy associated with cardiac benefit or detriment is considered, and prospects for pharmacological intervention are discussed.
