Paradigm shift of the plasma membrane concept from the two-dimensional continuum fluid to the partitioned fluid: high-speed single-molecule tracking of membrane molecules.
TLDR
The high-speed single-molecule tracking methods are described, and a new model of a partitioned fluid plasma membrane and the involvement of the actin-based membrane-skeleton "fences" and anchored-transmembrane protein "pickets" in the formation of compartment boundaries are critically reviewed.

Detection of non-Brownian diffusion in the cell membrane in single molecule tracking.
TLDR
Using Monte Carlo simulations of particles undergoing short-term confined diffusion within a compartment and long-term hop diffusion between these compartments, the intricate relationships of these time-related experimental parameters with the intrinsic diffusion parameters have been clarified and indicated that by systematically varying the frame time and rate, the anomalous diffusion can be clearly detected and characterized.

From nestling calls to fledgling silence: adaptive timing of change in response to aerial alarm calls
TLDR
Supporting the authors' prediction, recently fledged white-browed scrubwrens, Sericornis frontalis, fell silent immediately after playback of their parents' aerial alarm call, whereas nestlings continued to calling despite hearing the playback, suggesting that Young scrub wrens are exquisitely adapted to the changing risks faced during development.

Recent Physical Encounters Affect Chemically Mediated Retreat-Site Selection in a Gecko
TLDR
The notion that recent physical social encounters can affect the way that animals respond to chemical information from potential competitors is supported. Expand
