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

After 15 years with the journal, Julian Dow from University of Glasgow, UK, is stepping down as a Monitoring Editor. We wish Julian all the best for the future and welcome John Terblanche, Stellenbosch University, South Africa, who is joining the team. Julian talks about his long association with The Company of Biologists and the journal and John tells us about his life and career in this News article.
Ecotourism affecting iguana glucose tolerance
-Iguanas.jpg?versionId=3667)
Ecotourists feeding grapes on skewers to north Bahamian rock iguanas may be doing the reptiles more harm than good as the sugar charged diet is giving the animals high blood sugar.
Evolution of metabolic plasticity
-MetabolicPlasticity.png?versionId=3667)
In their Commentary, Frank Seebacher and Julian Beaman propose that metabolic plasticity originated in prebiotic protocells and that it was a pre-requisite for effective transfer of genetic material across generations – the hallmark of Darwinian evolution.
