Two decades of three-dimensional movement data from adult female northern elephant seals.

Northern elephant seals (Mirounga angustirostris) have been integral to the development and progress of biologging technology and movement data analysis, which continue to improve our understanding of this and other species. Adult female elephant seals at Año Nuevo Reserve and other colonies along the west coast of North America were tracked annually from 2004 to 2020, resulting in a total of 653 instrument deployments. This paper outlines the compilation and curation process of these high-resolution diving and location data, now accessible in two Dryad repositories.

Coyotes can do 'puppy dog eyes' too: comparing interspecific variation in facial expression muscles.

Facial expressions are critical for non-verbal communication. The genus epitomizes the interplay between behaviour and morphology in the evolution of non-verbal communication. Recent work suggests that the levator anguli oculi medialis (LAOM) muscle is unique to dogs () within the genus and evolved due to domestication.

Biochemical and Structural Consequences of NEDD8 Acetylation.

Similar to ubiquitin, the ubiquitin-like protein NEDD8 is not only conjugated to other proteins but is itself subject to posttranslational modifications including lysine acetylation. Yet, compared to ubiquitin, only little is known about the biochemical and structural consequences of site-specific NEDD8 acetylation. Here, we generated site-specifically mono-acetylated NEDD8 variants for each known acetylation site by genetic code expansion.

Using COVID-19 online learning modules to examine concerns of university students returning to in-person learning: a mixed-methods study.

Objective: Understand student concerns with returning to in-person instruction during the COVID-19 pandemic using an e-learning module.

Participants: 925 undergraduate and graduate students returning to in-person instruction in Fall 2021.

Methods: Five modules educated students about COVID and the transition to in-person learning and collected quantitative and qualitative data related to concerns about COVID and in-person learning.

Electrostatic and steric effects underlie acetylation-induced changes in ubiquitin structure and function.

Covalent attachment of ubiquitin (Ub) to proteins is a highly versatile posttranslational modification. Moreover, Ub is not only a modifier but itself is modified by phosphorylation and lysine acetylation. However, the functional consequences of Ub acetylation are poorly understood.
