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.

In spiders, social isolation is responsible for the development of aggressive behaviour. In a study published in the Journal of Experimental Biology, Emilie Mauduit and Raphael Jeanson show that social tolerance can be restored if spiders are exposed to siblings after moulting.
