Summary

In this conference, Audrey Dussutour, a CNRS research director, presents the fascinating biology of the blob (Physarum polycephalum), a single-celled organism that challenges our understanding of intelligence. She begins with an anecdote about a Texas woman who discovered a mysterious yellow creature in her garden, which turned out to be a blob. She explains that the blob is not an animal, plant, or fungus, but belongs to the Amoebozoa group, specifically the Myxomycetes class. The blob has a single cell but contains multiple nuclei, allowing it to regenerate and fuse with other blobs. It moves, feeds on bacteria and fungi, and has a complex life cycle involving spores and sexual reproduction. Dussutour highlights the blob’s remarkable abilities: it can learn, memorize, and solve problems, despite lacking a brain. She describes experiments showing habituation and memory transfer, and mentions the blob’s journey to the ISS. The talk also covers the blob’s role in education and its potential for inspiring new materials. Dussutour emphasizes that the blob is a model organism for studying cognition and decision-making, and she encourages the audience to observe and experiment with blobs at home.
