A screenshot of the PDF of the article titled 'Navigating in clutter: how bumblebees optimize flight behaviour through experience' by Manon Jeschke, Maximilian Stahlsmeier, Martin Egelhaaf and Olivier J. N. Bertrand. The publishing information states, '© 2025. Published by The Company of Biologists | Journal of Experimental Biology (2025) 228, jeb250514. doi:10.1242/jeb.250514'. The first line of the Abstract reads 'Bumblebees are excellent navigators that travel long distances while following paths to known locations.'

Even after travelling 5km from their hive, bumblebees navigate back without getting lost. In their recent article, Jeschke & co show that the bees fly home more quickly if they've had experience, avoiding obstacles and taking a straighter path back

A photo taken with a transmission electron microscope showing a slice through the small intestine of a Burmese python and depicts the apical crypt and calcium-containing spheroid in a specialized enterocyte. In the centre is an irregularly shaped spheroid which contains rings of calcium deposited over time, much like the rings of a tree. Underneath the spheroid are the small microvilli characteristic of these specialized cells. The grey cells to the right and left of the cell containing the spheroid are normal enterocytes which have the long microvilli normally found in pythons as they are digesting a meal.

In their Integrative Biology of the Gut SI article, Lignot & co report on a new type of cell found in the small intestine of pythons which allow the snakes to get rid of the excess calcium they absorb from digesting the skeletons of their large meals

A screenshot of the Commentary titled 'Bridging digestive physiology and ecology for a more integrative understanding of invertebrate predators' by Shawn Wilder, Colton Herzog, Jamie Reeves, Olivia Knowles and Jordan Cuff.

In their Commentary for the Integrative Biology of the Gut Special Issue, Wilder & co show the connections between the digestive physiology and ecology of invertebrate predators and suggest avenues for future study in this area

A graph depicting the contractile amplitude on the y-axis and the contraction frequency on the x-axis of the stomach muscles of a shortfin sculpin. In blue on the left, the graph shows the contractions at 4 degrees Celsius which show high amplitude, but low frequency. On the right, in red, the graph shows contractions of the muscle at 14 degrees Celsius which are more frequent, but have a lower amplitude. In the top right hand corner is a depiction of a shortfin sculpin.

In their Review for the Integrative Biology of the Gut Special Issue, Olsson & co discuss why understanding gut motility and how it changes in response to climate change is crucial for predicting if a species will survive in changing environments

On the left is the subheading 'WT atp4a +/+ with a depiction of a fish called Astyanax mexicanus beneath the subheading. Below this is the subheading 'WT atp4a -/- with the same a depiction an Astyanax mexicanus beneath the subheading. In the middle is a bracket connecting the two fish depictions leading to the words 'Reduced confounding factors' showing that there are advantages to using gene editing rather than comparing different species.

In their Commentary, Ferreira & co explore the repeated evolutionary loss of the stomach in fishes, describe how this affects their digestion, discuss our current understanding of how the stomach helps digest proteins and highlight unresolved questions
