Today, digital traces are widely exploited by social networks and online commerce on the Internet. In this work we show that in a non-competitive context, the use of digital traces favors the emergence of cooperation in a group of individuals performing an information search task. On the contrary, when the context becomes competitive, their use favors individualistic behavior and the exchange of unreliable or misleading information between individuals.
From 28 to 30 August, the CRCA-CBI hosted the 31st conference of the French section of the International Union for the Study of Social Insects.

In a new study, Audrey Dussutour, Angèle Rolland, Emilie Pasquier, Paul Malvezin, Cassandra Craig and Mathilde Dumas (CRCA-CBI) studied how the behavior of the slime mold Physarum Polycephalum, a unicellular organism, varies over the lifetime of individuals, and they showed that aging in the blob might be partially reversible.
