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.

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.

Division of labour is seen in many social organisms. A study based on a theoretical model and published in the journal Nature Communications shows that resource sharing is sufficient for the emergence of the division of labour within a group of initially identical individuals.

Sheep in the field alternate graphing phases when they are static or moving slowly and phases when they are moving, at a higher speed, in most cases collectively in a single file. We investigate the rules that could explain these intermittent file movements.
