An update on pacemaking in the myometrium

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The spread of multiple electrical signals (panel A, blue‐to‐red indicates increasing electrical excitability) that are spatiotemporally distinct, yet in‐phase with the excitatory episode, determines action potential shape and form (panel B, as recorded by single cell microelectrodes) and ensures contractile amplitude and duration

The Development and Failure of Social Norms in Second Life [PDF]

open access: yes, 2008
This Note analyzes the development and efficacy of social norms in maximizing the welfare of participants in the virtual community of Second Life. Although some of these norms developed appropriately in response to the objectives and purposes of this ...

A machine-learning approach to assign species to ‘unidentified’ entangled whales

open access: yesEndangered Species Research, 2018
Whale entanglements in US west coast fishing gear are largely represented by opportunistic sightings, and some reports lack species identifications due to rough seas, distance from whales, or a lack of cetacean identification expertise.

A NEW RECORD OF PHYSETEROIDEA FROM THE UPPER MIOCENE OF THE PIETRA LECCESE (SOUTHERN ITALY): SYSTEMATICS, PALEOECOLOGY AND TAPHONOMY OF A FOSSIL MACRORAPTORIAL SPERM WHALE

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2020
We report on a partial skeleton of sperm whale (Cetacea, Odontoceti, Physeteroidea) from the Pietra leccese, a Miocene limestone widely exposed in the Salento Peninsula (southern Italy).

Toward a Species Search Engine: KISSE Offers a Rigorous Statistical Framework for Bone Collagen Tandem Mass Spectrometry Data

open access: yesAdvanced Science, Volume 12, Issue 40, October 27, 2025.
The Species Search Engine (KISSE) is a novel statistical approach for identifying species from collagen peptides, using a curated library of sequences and their relative abundances derived from shotgun proteomics. Abstract DNA and bone collagen are two key sources of resilient molecular markers used to identify species from their remains.

Transatlantic Surveys of Seabirds, Cetaceans and Turtles, July 2013 and July 2018 [PDF]

open access: yes, 2018
Analysis of multi-species tracking data suggest that an area of the deep northwest Atlantic bounded by Flemish Cap, Charlie-Gibbs Fracture Zone and Mid-Atlantic Ridge (MAR) has a relatively high abundance and diversity of pelagic seabirds.

Genetic Diversity and Inter‐Specific Phylogeny of Three Sympatric Cetacean Species (Stenella spp.) in Thai Territorial Waters Based on Mitochondrial and Nuclear DNA Markers

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study investigated the genetic diversity, population structure, and hybridization among three Stenella dolphin species (S. longirostris, S. attenuata, S. coeruleoalba) in Thailand's Andaman Sea using microsatellite loci and mitochondrial DNA from 113 stranded specimens.

The Evil of Banality: Moby Dick vs. the Extreme Machine [PDF]

open access: yes, 2004
In this article I am suggesting that Feidelson’s approach be appropriated for the contemplation and understanding of extra-literary phenomena like the extreme machine. As Russell Reising points out, Feidelson’s “historical premise—that symbolism arose at

Leveraging Synteny to Generate Reference Genomes for Conservation: Assembling the Genomes of Hector's and Māui Dolphins

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT Escalating concern regarding the impacts of reduced genetic diversity on the conservation of endangered species has spurred efforts to obtain chromosome‐level genomes through consortia such as the Vertebrate Genomes Project. However, assembling reference genomes for many threatened species remains challenging due to difficulties obtaining ...
