Animal survival depends on effective attack and defense strategies, yet how these behaviors arise remains unclear. Addressing this question, a recent study shows that predator and prey behaviors emerge naturally as stable patterns shaped by simple sensory abilities and motor rules. These patterns correspond to Nash equilibria—states in which neither predator nor prey can improve its outcome by unilaterally changing behavior—providing a theoretical framework for understanding predator–prey interactions.

A new opinion paper argues that proprioception should be redefined beyond a fixed biological feedback loop. The authors propose that proprioception should be better understood as a dynamic, interpretable interface that can be edited, augmented, and potentially surpassed through engineered signals—an idea that could reshape rehabilitation strategies and open new directions for performance enhancement in elite athletes.

Chemotherapy exerts systemic effects that extend beyond direct tumor cell killing, according to a new study led by Tatiana Petrova, professor at the Faculty of Biology and Medicine at the University of Lausanne, and published in Nature Communications.
