A new approach measures the respective participations of elementary cell behaviors – such as cell division, intercalation, shape change and death – in the shaping of animal tissues.

Sequencing and counting RNAs from single cells can create a misleading picture of alternative splicing if too many mRNAs are lost in the process.

The nearly universal nature of scaled cell shape variability in an epithelial monolayer is unavoidable, irrespective of health or disease, as it comes from a mathematical property.

Through mathematical analysis and computer simulations, the neuronal underpinnings of feasible models of sequence learning are delineated.

Computational and theoretical analyses offer novel and unexpected insight into how complex, naturally occurring odor mixtures are parsed and normalized at the very first stage of olfaction.

The motor protein kinesin utilizes its fuel molecule by active and concerted motions of its subdomains, while it rapidly interacts with the microtubule track by forming a wet and dynamic interface.

Learning to reach in the sensorimotor loop, and the required neural dynamics, can be potentially explained by simple principles.

The organization of olfactory projection neurons and their synaptic connectivity with third-order neurons studied along with olfactory responses suggest that the labeled-line design is partially at work in the Drosophila olfactory system.

Bacteria can exhibit herd immunity protection against phages, which may play a significant role in their ecology and evolution.

Topographic maps can gradually increase the fidelity of sensory representations and improve signal-to-noise ratio across multiple cortical circuits, a generic architectural feature that depends solely on the modularity of topographic projections and recurrent inhibition.
