Cover ImageCover: In Amphimedon queenslandica larvae, phototaxis is conferred by posterior, concentric rings of pigmented and ciliated cells. This image is artificially colored to highlight ciliated cells (purple) that act as light-responsive 'rudders' to steer the living larvae. Because sponges are not known to possess nervous systems or opsins, the molecular components of sponge phototaxis must differ from other animals. Rivera et al. (pp. 1278−1286) characterize two cryptochrome genes in A. queenslandica. One is expressed near the pigment ring, and its protein contains a co-factor responsive to wavelengths of light that also mediate photic behavior, suggesting a cryptochome may act in the aneural, opsin-less eye of a sponge.

The Forest of Biologists
We are excited to announce the launch of The Forest of Biologists, a new biodiversity initiative created with support from the Woodland Trust, aiming to counteract nature loss and safeguard some of the most critically endangered ecosystems for future generations. Do take a look around our virtual forest. For every Research Article and Review/Commentary article that is published in JEB, a native tree is planted in a forest in the UK.
Celebrating 100 years of discovery
We are proud to be celebrating 100 years of discovery in Journal of Experimental Biology. Visit our centenary webpage to find out more about how we are marking this historic milestone.
Looking back on the first issue of JEB
Journal of Experimental Biology launched in 1923 as The British Journal of Experimental Biology. As we celebrate our centenary, we look back at that first issue and the zoologists publishing their work in the new journal.
In our new Conversation series JEB@100, JEB Editor-in-Chief Craig Franklin talks about the big outstanding questions in the field of physiological plasticity and why he thinks a sense of community is key to the journal's success. Find out more here.
Deer mice overheat and struggle to run in high temperatures
Matthew Eizenga and colleagues show that deer mice run comfortably at 25C, but as the temperature rises the tiny rodents start to struggle and they begin overheating at air temperatures of 38C, which could be a big problem for the animals in future climate scenarios.
Propose new workshop for 2025
Do you have an idea for a Workshop? We are now accepting proposals for our 2025 Biologists Workshops programme. As the scientific organiser, your involvement will be focused on the science. We'll take care of all the logistics. In 2025 we'll continue our efforts to diversify our Workshop programme and will be reserving one of our Workshops for an application from a Global South (GS) country to host an event overseas.
