Cover ImageCover: In situ hybridization of the vegetal region of an 8-cell stage Xenopus laevis embryo using a probe for Wnt11 mRNA, showing that Wnt11 mRNA is localized in dorsal vegetal blastomeres. Depletion of Wnt11, or of its receptor LRP6, leads to loss of axis formation. (In situ by Stephanie Lang.) See research article by Kofron et al. on p. 503

The Forest of Biologists
The Forest of Biologists is a biodiversity initiative created by The Company of Biologists, with support from the Woodland Trust. For every Research and Review article published in Development a native tree is planted in a UK forest. In addition to this we are protecting and restoring ancient woodland and are dedicating these trees to our peer reviewers. Visit our virtual forest to learn more.
Propose a 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.
Development presents… Outstanding Paper Prize Finalists
On Wednesday 19 April, Development hosted a webinar celebrating the finalists for Development’s Inaugural Outstanding Paper Prize. The talks and Q&As were hosted by our Deputy Editor, Steve Wilson (UCL).

Keeping up with the Node
Thirteen years on from its launch, the Node continues to be a place to share research stories, opinions, job adverts and event listings. Development have published a recent Editorial reviewing some of our most popular features, as well as introducing some new initiatives.
