When active filaments are exposed to localized illumination, they accumulate into stable structures along the boundaries of the illuminated area. Based on this fact, researchers developed a model that can be used to simulate the self-organization of thread-like living matter.
This model provides important insights for potential technical applications in the formation of structures.
Filamentous cyanobacteria aggregate in areas with favorable light conditions and use the light energy for photosynthesis. Typically, these microorganisms form long filaments consisting of many cells. However, the thread-like structures can only move forward or backward -- when leaving the illuminated area, they reverse their movement and thus remain in the light. Scientists at MPI-DS have investigated the resulting organizational structures.
The insights gained from the scientists' experiments and the resulting model can also be applied to living matter with comparable morphology."The model does not include any specific details regarding the biology of the bacteria," says Leila Abbaspour, joint first author of the study together with Maximilian Kurjahn.

Evolution in real time | ScienceDailySnails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population of the same snail species, these evolved to strikingly resemble the population lost over 30 years prior.
