Announcing the 2024 JEB Outstanding Paper Prize shortlist and winner

Every year JEB celebrates early-career researchers through the Outstanding Paper Prize. We recognise the shortlisted ECRS that contributed to 11 remarkable studies published in 2024 and congratulate the winner, Elise Laetz, from University of Groningen. See how else JEB supports and promotes ECRs.

Inside the Intergovernmental Panel on Climate Change with Hans-Otto Pörtner

During the past two decades, Hans-Otto Pörtner has steered climate change policy as a co-Chair of IPCC Working Group II. He tells us about the experience in this Perspective.

Photosynthesis turns symbiotic sea anemone's tentacles toward sun

Snakelocks sea anemones point their tentacles, packed with symbiotic algae, toward the sun so their lodgers can photosynthesize, and now Vengamanaidu Modepalli & colleagues have discovered that photosynthesis by the algae guides their host's tentacles towards the sun.

History of our journals

As our publisher, The Company of Biologists, turns 100 years old, read about JEB’s history and explore the journey of each of our sister journals: Development, Journal of Cell Science, Disease Models & Mechanisms and Biology Open.
