25 January 2024 An oval light blue shape. In the central part, there is a smaller a red object, from which stem many highly branched smaller canals that cover a significant part of the blue surface. The whole sponge image is in placed in a circle. The background around the circle is blue-green.

Ancient ‘relaxant-inflammatory’ response gets sponges moving

Sponges lack muscles and neurons. Yet, they make coordinated movements. Scientists at EMBL Heidelberg have discovered that sponge movement is controlled by an ancient ‘relaxant-inflammatory’ response that is also present in vertebrate blood vessels. The findings shed light on sponge physiology…

More than a gut reaction

What can sponges tell us about the evolution of the brain? Sponges have the genes involved in neuronal function in higher animals. But if sponges don’t have brains, what is the role of these? EMBL scientists imaged the sponge digestive chamber to find out.

A cellular atlas of an entire worm

EMBL scientists and colleagues have developed an interactive atlas of the entire marine worm Platynereis dumerilii in its larval stage. The PlatyBrowser resource combines high-resolution gene expression data with volume electron microscopy images.

Brainy worms: Evolution of the cerebral cortex

Our cerebral cortex, or pallium, is a big part of what makes us human: art, literature and science would not exist had this most fascinating part of our brain not emerged in some less intelligent ancestor in prehistoric times. But when did this occur and what were these ancestors? Unexpectedly,…

MicroRNA: a glimpse into the past

The last ancestor we shared with worms, which roamed the seas around 600 million years ago, may already have had a sophisticated brain that released hormones into the blood and was connected to various sensory organs. The evidence comes not from a newly found fossil but from the study of microRNAs…
