A multiphase hydrodynamic theory reveals that the dynamics of colony expansion in microbial swarms and biofilms are limited by the constraints of water and nutrient availability.
A human psychopharmacology study reveals that a drug that affects the dopamine and noradrenaline systems enhances people's ability to adapt their learning rate to suit the volatility of the environment.
Motivational coupling of action to reward and inhibition to punishment is subserved by dissociable learning and choice processes, and is modulated by dopamine/noradrenaline transporter blockade.
Killer T cells swarm around tumour targets by accelerating the recruitment of distant T cells, which upon arrival and target engagement augment the chemotactic signal in a positive feedback loop.
Two seemingly distinct behaviors in social C. elegans worms, namely aggregating into groups and swarming over food, are driven by the same underlying mechanisms.
The machinery that carries out programmed DNA rearrangements is composed of domesticated transposases. One is catalytically active, five play architectural function essential for the accuracy of the process.
Female mosquitoes are exquisitely sensitive to human body heat, and the TRPA1 gene is required to focus their attraction toward thermal stimuli resembling warm-blooded hosts.
Standing genetic variation for disease resistance may be continuously lost during recurring warm water episodes because of widespread susceptibility of disease-resistant genotypes to bleaching and the independence between these two traits.
