Cover: The mechanism of absorption of sugars by Egyptian fruit bats (Rousettus aegyptiacus) has been enigmatic because early tests for glucose transport through enterocytes and against a concentration gradient were all negative, despite the high efficiency of uptake by these bats. Thus, it had been hypothesized that glucose transport in the intestine of these bats must occur via a paracellular route between enterocytes, rather than through the cells. Measurements of sugar transport by these two alternate pathways suggest that, unlike most mammals measured to date, most sugar transport in these bats is paracellular (see article by C. R. Tracy et al., pp. 1726−1734). (Photo credit: Amram Zabari, Midreshet Ben-Gurion, Israel.) - PDF Icon PDF LinkTable of contents

Extraordinary creatures: mantis shrimp
In our new Conversation series focusing on extraordinary creatures, Tom Cronin and Sheila Patek tell us about the incredible biology of mantis shrimp, from their complex vision to their powerful striking abilities.
Behaviour as a physiological process
In this Commentary, Shamil Debaere & colleagues argue the case for integration of behaviour into animal physiology, and advocate for behaviour to be considered as a physiological process.
Tiny ring-necked snakes keep warm heads despite their size
Some ectotherms are able to raise the temperature of certain body parts above the temperature of other regions & now Christian Fox and Albert Chung, with undergraduates from the University of Virginia, reveal that the heads of tiny ring-necked snakes can be 2.1C warmer than their tails, even though they are only 20cm long.
