A longer birdsong-learning window evolves in response to sexual selection for song complexity and is associated with faster evolution of song performance characteristics.

An NMR-based structural study of sperm proteins reveals a novel protein packaging/dispersion system embedded in a coevolutionary arms race.

The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

A new pipeline of electron microscopy techniques reduces the time required to visualize genetically targeted neurons and their connections by two orders of magnitude.

Nematode sperm respond to competitive environments by modulating cellular pathways involved in migration and storage to ensure their access to oocytes.

Gaining genetic control over neural modules that drive the grooming of each Drosophila body part reveals how mechanisms for selecting among competing behavioral choices are used to generate sequences of actions.

Three-dimensional electron microscopy (3DEM) demonstrates the dependence on presynaptic mitochondria for vesicle mobilization as dendritic spines are silently added at P15 or synapses are silently enlarged in adults after long-term potentiation.

A broadly applicable method that faithfully preserves genetically labeled cellular structures for 3D electron microscopy (EM) and correlated light and electron microscopy (CLEM).

The discovery of a biological switching valve provides an example of a mechanism that evolved in nature long before its invention by man and could inspire alternative valve technologies.
