Cover: Northern elephant seal (Mirounga angustirostris) pups naturally endure a 2−3?month post-weaning fast that is associated with insulin resistance (IR)-like conditions. Suzuki et al. (pp.?3215−3221) assessed the effects of this post-weaning fast on systemic and local renin−angiotensin systems (RAS) because inappropriate activation of RAS is known to contribute to the development of IR, possibly through RAS-mediated overexpression of cytokines. They showed that prolonged fasting resulted in systemic RAS activation, an increase in muscle TNF-α and suppression of adipose adiponectin, which are coordinated events that likely contribute synergistically to the development of IR-like conditions, independent of local RAS activity. - PDF Icon PDF LinkTable of contents

Ecophysiological responses to heat waves in the marine intertidal zone

Heat waves are intensifying with climate change and intertidal zones are the only ecosystem to experience both atmospheric and marine heat waves. In this Review, Jonathon Stillman and colleagues highlight the physiological impacts of heat waves on intertidal organisms, including effects on mortality, plasticity and adaptation.
Snakes require super-stretchy neck skin to consume massive mouthfuls

Some snakes are capable of gulping down meals that are far larger than their heads in a single mouthful and now Jarrod Petersen, Lucy Campbell and Thomas Roberts show that super-stretchy neck skin is likely one of the key factors that allowed boa constrictors and egg-eating snakes to evolve this extraordinary feat.
