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.)Close Modal - PDF Icon PDF LinkTable of contents

Sharpshooting archerfish brake to overcome recoil
Archerfish are exceptional snipers and now it turns out that they use their fins as brakes to counteract the recoil that would submerge them when taking out a target with a jet of water.
Responses of terrestrial polar arthropods to high and increasing temperatures
In a Review of thermal adaptation of polar terrestrial arthropods to high temperatures, Bahrndorff et al. conclude that a large variation in upper thermal limits exists across polar regions, habitats and species.
