Recordings from serotonin-producing neurons in the brain reveal that these neurons are highly activated by sudden changes in previously familiar environments, potentially explaining why serotonin is important for learning to adapt to such changes.

Conserved contacts on cognate ligands trigger an induced fit pathway that confers selective promiscuity to PD-1, a flexible regulatory protein and promising anticancer target.

Harbor porpoises dynamically control biosonar field of view as they track and capture prey, focusing the beam through deformations to the melon.

The amination network for the distribution of assimilated ammonium throughout metabolism is defined by promiscuous transaminases, allowing a high flexibility of the network that supported engineering novel connections and even alternative ammonium assimilation entry points.

Oxytocin was found to significantly improve non-social decision making in a healthy sample, suggesting a domain-general function of the hormone, in contrast to its previously hypothesized social domain specificity.

Individual performance in rhythm perception and production is maximized within a range of domain-specific rates and is adversely affected by temporal context, and this effect is amplified with age.

The core of histone acetyltransferase complex, NuA4, flexibly tethers various histone recognition modules, including the HAT module which is capable of binding nucleosomes marked by H3K4me3 and H3 acetylation.

An automated touchscreen cognitive testing system for rats reduces the length of training required to learn tasks, making it possible to assess cognitive profiles in adolescent animals to more appropriately capture cognitive deficits in adolescent pathologies, such as anorexia nervosa.

Lab-evolved 'super Spy' chaperones show enhanced flexibility, which allows them to bind to and stabilize proteins more effectively than natural chaperones.

The courtship master gene fruitless tunes functional flexibility of courtship circuitry during development instead of switching on its function as conventionally viewed.
